Sex education

Sex education may also be described as "sexuality education," which means that it encompasses education about all aspects of sexuality, including information about family planning, reproduction (fertilization, conception and development of the embryo and fetus, through to childbirth), plus information about all aspects of one's sexuality including: body image, sexual orientation, sexual pleasure, values, decision making, communication, dating, relationships, sexually transmitted infections (STIs) and how to avoid them, and birth control methods.

Sex education may be taught informally, such as when someone receives information from a conversation with a parent, friend, religious leader, or through the media. It may also be delivered through sex self-help authors, magazine advice columnists, sex columnists, or through sex education web sites. Formal sex education occurs when schools or health care providers offer sex education.

Sometimes formal sex education is taught as a full course as part of the curriculum in junior high school or high school. Other times it is only one unit within a more broad biology class, health class, home economics class, or physical education class. Some schools offer no sex education, since it remains a controversial issue in several countries, particularly the United States (especially with regard to the age at which children should start receiving such education, the amount of detail that is revealed, and topics dealing with human sexual behavior, eg. safe sex practices, masturbation, premarital sex, and sexual ethics).

In 1936, Wilhelm Reich commented that sex education of his time was a work of deception, focusing on biology while concealing excitement-arousal, which is what a pubescent individual is mostly interested in. Reich added that this emphasis obscures what he believed to be a basic psychological principle: that all worries and difficulties originate from unsatisfied sexual impulses.

When sex education is contentiously debated, the chief controversial points are whether covering child sexuality is valuable or detrimental; the use of birth control such as condoms and hormonal contraception; and the impact of such use on pregnancy outside marriage, teenage pregnancy, and the transmission of STIs. Increasing support for abstinence-only sex education by conservative groups has been one of the primary causes of this controversy. Countries with conservative attitudes towards sex education (including the UK and the U.S.) have a higher incidence of STIs and teenage pregnancy.

The existence of AIDS has given a new sense of urgency to the topic of sex education. In many African nations, where AIDS is at epidemic levels (see HIV/AIDS in Africa), sex education is seen by most scientists as a vital public health strategy. Some international organizations such as Planned Parenthood consider that broad sex education programs have global benefits, such as controlling the risk of overpopulation and the advancement of women's rights (see also reproductive rights).

According to SIECUS, the Sexuality Information and Education Council of the United States, 93% of adults they surveyed support sexuality education in high school and 84% support it in junior high school. In fact, 88% of parents of junior high school students and 80% of parents of high school students believe that sex education in school makes it easier for them to talk to their adolescents about sex. Also, 92% of adolescents report that they want both to talk to their parents about sex and to have comprehensive in-school sex education.

Sex education worldwide

Afica
Sex education in Africa has focused on stemming the growing AIDS epidemic. Most governments in the region have established AIDS education programs in partnership with the World Health Organization and international NGOs. These programs were undercut significantly by the Global Gag Order, an initiative put in place by President Reagan, suspended by President Clinton, and re-instated by President Bush. The gag order refused government funding for any efforts that promote condom and contraception use in addition to abstinence and monogamy. The Global Gag Order was again suspended as one of the first official acts by President Barack Obama. The incidences of new HIV transmissions in Uganda decreased dramatically when Clinton supported a comprehensive sex education approach (including information about contraception and abortion). According to Ugandan AIDS activists, the Global Gag Order undermined community efforts to reduce HIV prevalence and HIV transmission.

Egypt teaches knowledge about male and female reproductive systems, sexual organs, contraception and STDs in public schools at the second and third years of the middle-preparatory phase (when students are aged 12–14). A coordinated program between UNDP, UNICEF, and the ministries of health and education promotes sexual education at a larger scale in rural areas and spreads awareness of the dangers of female genital cutting.


Asia
The state of sex education programs in Asia is at various stages of development. Indonesia, Mongolia, South Korea and Sri Lanka have a systematic policy framework for teaching about sex within schools. Malaysia, the Philippines and Thailand have assessed adolescent reproductive health needs with a view to developing adolescent-specific training, messages and materials. India has programs aimed at children aged nine to sixteen years. In India, there is a huge debate on the curriculum of sex education and when should it be increased. Attempts by state governments to introduce sex education as a compulsory part of the curriculum have often been met with harsh criticism by political parties, who claim that sex education "is against Indian culture" and would mislead children. (Bangladesh, Myanmar, Nepal and Pakistan have no coordinated sex education programs.)

In Japan, sex education is mandatory from age 10 or 11, mainly covering biological topics such as menstruation and ejaculation.

In China, sex education traditionally consists in reading the reproduction section of biology textbooks. However, in 2000 a new five-year project was introduced by the China Family Planning Association to "promote reproductive health education among Chinese teenagers and unmarried youth" in twelve urban districts and three counties. This included discussion about sex within human relationships as well as pregnancy and HIV prevention.

The International Planned Parenthood Federation and the BBC World Service ran a 12-part series known as Sexwise, which discussed sex education, family life education, contraception and parenting. It was first launched in South Asia and then extended worldwide.


Europe

Finland
In Finland, sexual education is usually incorporated into various obligatory courses, mainly as part of biology lessons (in lower grades) and later in a course related to general health issues. The Population and Family Welfare Federation provides all 15-year-olds an introductory sexual package that includes an information brochure, a condom and a cartoon love story.


France
In France, sex education has been part of school curricula since 1973. Schools are expected to provide 30 to 40 hours of sex education, and pass out condoms, to students in grades eight and nine. In January 2000, the French government launched an information campaign on contraception with TV and radio spots and the distribution of five million leaflets on contraception to high school students.


Germany
In Germany, sex education has been part of school curricula since 1970. Since 1992 sex education is by law a governmental duty.

It normally covers all subjects concerning the growing-up process, body changes during puberty, emotions, the biological process of reproduction, sexual activity, partnership, homosexuality, unwanted pregnancies and the complications of abortion, the dangers of sexual violence, child abuse, and sex-transmitted diseases, but sometimes also things like sex positions. Most schools offer courses on the correct usage of contraception.

A sex survey by the World Health Organization concerning the habits of European teenagers in 2006 revealed that German teenagers care about contraception. The birth rate among 15- to 19-year-olds was very low.


The Netherlands
Subsidized by the Dutch government, the “Lang leve de liefde” (“Long Live Love”) package, developed in the late 1980s, aims to give teenagers the skills to make their own decisions regarding health and sexuality. Nearly all secondary schools provide sex education as part of biology classes and over half of primary schools discuss sexuality and contraception. The curriculum focuses on biological aspects of reproduction as well as on values, attitudes, communication and negotiation skills. The media has encouraged open dialogue and the health-care system guarantees confidentiality and a non-judgmental approach. The Netherlands has one of the lowest teenage pregnancy rates in the world, and the Dutch approach is often seen as a model for other countries.


Sweden
In Sweden, sex education has been a mandatory part of school education since 1956. The subject is usually started between ages 7 and 10, and continues up through the grades, incorporated into different subjects such as biology and history.


Switzerland
In Switzerland, the content and amount of sex education is decided at the cantonal level. In Geneva, courses have been given at the secondary level since the 1950s. Interventions in primary schools were started more recently, with the objective of making children conscious of what is and isn't allowed, and able to say "No". In secondary schools (age 13-14), condoms are shown to all pupils, and are demonstrated by unfolding over the teacher's fingers. For this, classes are usually separated into girl-only and boy-only subgroups. Condoms are not distributed, however, except among older adolescents engaged in state-run non-compulsory education (age 16-17).


United Kingdom
In England and Wales, sex education is not compulsory in schools as parents can refuse to let their children take part in the lessons. The curriculum focuses on the reproductive system, fetal development, and the physical and emotional changes of adolescence, while information about contraception and safe sex is discretionary and discussion about relationships is often neglected. Britain has one of the highest teenage pregnancy rates in Europe and sex education is a heated issue in government and media reports. In a 2000 study by the University of Brighton, many 14 to 15 year olds reported disappointment with the content of sex education lessons and felt that lack of confidentiality prevents teenagers from asking teachers about contraception.In a 2008 study conducted by YouGov for Channel 4 it was revealed that almost three in ten teenagers say they need more sex and relationships education.

In Scotland, the main sex education program is Healthy Respect, which focuses not only on the biological aspects of reproduction but also on relationships and emotions. Education about contraception and sexually transmitted diseases are included in the program as a way of encouraging good sexual health. In response to a refusal by Catholic schools to commit to the program, however, a separate sex education program has been developed for use in those schools. Funded by the Scottish Government, the program Called to Love focuses on encouraging children to delay sex until marriage, and does not cover contraception, and as such is a form of abstinence-only sex education.

Sex education in United States

Almost all U.S. students receive some form of sex education at least once between grades 7 and 12; many schools begin addressing some topics as early as grades 5 or 6. However, what students learn varies widely, because curriculum decisions are so decentralized. Many states have laws governing what is taught in sex education classes or allowing parents to opt out. Some state laws leave curriculum decisions to individual school districts.

For example, a 1999 study by the Guttmacher Institute found that most U.S. sex education courses in grades 7 through 12 cover puberty, HIV, STIs, abstinence, implications of teenage pregnancy, and how to resist peer pressure. Other studied topics, such as methods of birth control and infection prevention, sexual orientation, sexual abuse, and factual and ethical information about abortion, varied more widely.

Two main forms of sex education are taught in American schools: comprehensive and abstinence-only. Comprehensive sex education covers abstinence as a positive choice, but also teaches about contraception and avoidance of STIs when sexually active. A 2002 study conducted by the Kaiser Family Foundation found that 58% of secondary school principals describe their sex education curriculum as comprehensive.

Abstinence-only sex education tells teenagers that they should be sexually abstinent until marriage and does not provide information about contraception. In the Kaiser study, 34% of high-school principals said their school's main message was abstinence-only.

The federal government plays a large role in which form of sex education is taught in public schools. In 1996, Congress passed a law to fund abstinence-only sex education. The federal government only funds abstinence-only sex education.

The difference between these two approaches, and their impact on teen behavior, remains a controversial subject. In the U.S., teenage birth rates had been dropping since 1991, but a 2007 report showed 3% increase from 2005 to 2006. From 1991 to 2005, the percentage of teens reporting that they had ever had sex or were currently sexually active showed small declines.[25] However, the U.S. still has the highest teen birth rate and one of the highest rates of STIs among teens in the industrialized world. Public opinion polls conducted over the years have found that the vast majority of Americans favor broader sex education programs over those that teach only abstinence, although abstinence educators recently published poll data with the opposite conclusion.

Proponents of comprehensive sex education, which include the American Psychological Association, the American Medical Association, the National Association of School Psychologists, the American Academy of Pediatrics, the American Public Health Association, the Society for Adolescent Medicine and the American College Health Association, argue that sexual behavior after puberty is a given, and it is therefore crucial to provide information about the risks and how they can be minimized; they also claim that denying teens such factual information leads to unwanted pregnancies and STIs.

On the other hand, proponents of abstinence-only sex education object to curricula that fail to teach their standard of moral behavior; they maintain that a morality based on sex only within the bounds of marriage is "healthy and constructive" and that value-free knowledge of the body may lead to immoral, unhealthy, and harmful practices. Within the last decade, the federal government has encouraged abstinence-only education by steering over a billion dollars to such programs. Some 15 states now decline the funding so that they can continue to teach comprehensive sex education. Funding for one of the federal government's two main abstinency-only funding programs, Title V, was extended only until December 31, 2007; Congress is debating whether to continue it past that date.

The impact of the rise in abstinence-only education remains a question. To date, no published studies of abstinence-only programs have found consistent and significant program effects on delaying the onset of intercourse. In 2007, a study ordered by the U.S. Congress found that middle school students who took part in abstinence-only sex education programs were just as likely to have sex (and use contraception) in their teenage years as those who did not. Abstinence-only advocates claimed that the study was flawed because it was too narrow and began when abstinence-only curricula were in their infancy, and that other studies have demonstrated positive effects.

Alternative medicine

The term alternative medicine, as used in the modern western world, encompasses any healing practice "that does not fall within the realm of conventional medicine". Commonly cited examples include naturopathy, chiropractic, herbalism, traditional Chinese medicine, Unani, Ayurveda, meditation, yoga, biofeedback, hypnosis, homeopathy, acupuncture, and diet-based therapies, in addition to a range of other practices. It is frequently grouped with complementary medicine, which generally refers to the same interventions when used in conjunction with mainstream techniques, under the umbrella term complementary and alternative medicine, or CAM. Some significant researchers in alternative medicine oppose this grouping, preferring to emphasize differences of approach, but nevertheless use the term CAM, which has become standard.

Alternative medicine practices are as diverse in their foundations as in their methodologies. Practices may incorporate or base themselves on traditional medicine, folk knowledge, spiritual beliefs, or newly conceived approaches to healing.Jurisdictions where alternative medical practices are sufficiently widespread may license and regulate them. The claims made by alternative medicine practitioners are generally not accepted by the medical community because evidence-based assessment of safety and efficacy is either not available or has not been performed for many of these practices. If scientific investigation establishes the safety and effectiveness of an alternative medical practice, it may be adopted by conventional practitioners. Because alternative techniques tend to lack evidence, some have advocated defining it as non-evidence based medicine, or not medicine at all. Some researchers have noted that the evidence-based approach to defining CAM is problematic because some CAM is tested, and research suggests that many mainstream medical techniques lack solid evidence.

A 1998 systematic review of studies assessing its prevalence in 13 countries concluded that about 31% of cancer patients use some form of complementary and alternative medicine.Alternative medicine varies from country to country; Dr. Edzard Ernst believes that in Austria and Germany CAM is mainly in the hands of physicians, although some estimates suggest that half of CAM is administered by physicians in the US. In Germany, herbs are tightly regulated, with half prescribed by doctors and covered by health insurance based on their Commission E legislation

Alternative and evidence-based medicine

Testing of efficacy
Many alternative therapies have been tested with varying results. In 2003, a project funded by the CDC identified 208 condition-treatment pairs, of which 58% had been studied by at least one randomized controlled trial (RCT), and 23% had been assessed with a meta-analysis. According a 2005 book by a US Institute of Medicine panel, the number of RCTs focused on CAM has risen dramatically. The book cites Vickers (1998), who found that many of the CAM-related RCTs are in the Cochrane register, but 19% of these trials were not in MEDLINE, and 84% were in conventional medical journals.:133

As of 2005 the Cochrane Library had 145 CAM-related Cochrane systematic reviews and 340 non-Cochrane systematic reviews. An analysis of the conclusions of only the 145 Cochrane reviews was done by two readers. In 83% of the cases, the readers agreed. In the 17% in which they disagreed, a third reader agreed with one of the initial readers to set a rating. These studies found that for CAM, 38.4% concluded positive effect or possibly positive (12.4%) effect, 4.8% concluded no effect, 0.69% concluded harmful effect, and 56.6% concluded insufficient evidence. An assessment of conventional treatments found that 41.3% concluded positive or possibly positive effect, 20% concluded no effect, 8.1% concluded net harmful effects, and 21.3% concluded insufficient evidence. However, the CAM review used the 2004 Cochrane database while the conventional review used the 1998 Cochrane database.[15]:135-136

Most alternative medical treatments are not patentable, which may lead to less research funded by the private sector. Additionally, in most countries alternative treatments (in contrast to pharmaceuticals) can be marketed without any proof of efficacy—also a disincentive for manufacturers to fund scientific research. Some have proposed adopting a prize system to reward medical research. However, public funding for research exists. Increasing the funding for research of alternative medicine techniques was the purpose of the US National Center for Complementary and Alternative Medicine. NCCAM and its predecessor, the Office of Alternative Medicine, have spent more than $1 billion on such research since 1992. The German Federal Institute for Drugs and Medical Devices Commission E has studied many herbal remedies for efficacy.

Some skeptics of alternative practices point out that a person may attribute symptomatic relief to an otherwise ineffective therapy due to the placebo effect, the natural recovery from or the cyclical nature of an illness (the regression fallacy), or the possibility that the person never originally had a true illness.

In the same way as for conventional therapies, drugs, and interventions, it can be difficult to test the efficacy of alternative medicine in clinical trials. In instances where an established, effective, treatment for a condition is already available, the Helsinki Declaration states that withholding such treatment is unethical in most circumstances. Use of standard-of-care treatment in addition to an alternative technique being tested may produce confounded or difficult-to-interpret results.

Medical education

In the United States, increasing numbers of medical colleges have started offering courses in alternative medicine. For example, in three separate research surveys that surveyed 729 schools (125 medical schools offering an MD degree, 25 medical schools offering a Doctor of Osteopathic medicine degree, and 585 schools offering a nursing degree), 60% of the standard medical schools, 95% of osteopathic medical schools and 84.8% of the nursing schools teach some form of CAM. The University of Arizona College of Medicine offers a program in Integrative Medicine under the leadership of Dr. Andrew Weil which trains physicians in various branches of alternative medicine which "...neither rejects conventional medicine, nor embraces alternative practices uncritically." Accredited Naturopathic colleges and universities are also increasing in number and popularity in Canada and the USA. (See Naturopathic medical school in North America)

Similarly "unconventional medicine courses are widely represented at European universities. They cover a wide range of therapies. Many of them are used clinically. Research work is underway at several faculties,"[74] but "only 40% of the responding [European] universities were offering some form of CAM training."

In Britain, no conventional medical schools offer courses that teach the clinical practice of alternative medicine.[citation needed] However, alternative medicine is taught in several unconventional schools as part of their curriculum.[citation needed] Teaching is based mostly on theory and understanding of alternative medicine, with emphasis on being able to communicate with alternative medicine specialists.[citation needed] To obtain competence in practicing clinical alternative medicine, qualifications must be obtained from individual medical societies.[citation needed] The student must have graduated and be a qualified doctor.[citation needed] The British Medical Acupuncture Society, which offers medical acupuncture certificates to doctors, is one such example, as is the College of Naturopathic Medicine UK and Ireland.


[edit] Regulation
Due to the uncertain nature of various alternative therapies and the wide variety of claims different practitioners make, alternative medicine has been a source of vigorous debate, even over the definition of alternative medicine. Dietary supplements, their ingredients, safety, and claims, are a continual source of controversy. In some cases, political issues, mainstream medicine and alternative medicine all collide, such as the case where synthetic drugs are legal but the herbal sources of the same active chemical are banned. In other cases, controversy over mainstream medicine causes questions about the nature of a treatment, such as water fluoridation. Alternative medicine and mainstream medicine debates can also spill over into freedom of religion discussions, such as the right to decline lifesaving treatment for one's children because of religious beliefs. Government regulators continue to attempt to find a regulatory balance.

Jurisdiction differs concerning which branches of alternative medicine are legal, which are regulated, and which (if any) are provided by a government-controlled health service or reimbursed by a private health medical insurance company. The United Nations Committee on Economic, Social and Cultural Rights - article 34 (Specific legal obligations) of the General Comment No. 14 (2000) on The right to the highest attainable standard of health - states that

"Furthermore, obligations to respect include a State's obligation to refrain from prohibiting or impeding traditional preventive care, healing practices and medicines, from marketing unsafe drugs and from applying coercive medical treatments, unless on an exceptional basis for the treatment of mental illness or the prevention and control of communicable diseases."
Specific implementations of this article are, of course, left to member states.

A number of alternative medicine advocates disagree with the restrictions of government agencies that approve medical treatments. In the USA, for example, critics claim that the Food and Drug Administration's criteria for experimental evaluation methods impedes those seeking to bring useful and effective treatments and approaches to the public, and protest that their contributions and discoveries are unfairly dismissed, overlooked or suppressed. Alternative medicine providers recognize that health fraud occurs, and argue that it should be dealt with appropriately when it does, but that these restrictions should not extend to what they view as legitimate health care products.

In New Zealand alternative medicine products are classified as food products, so there are no regulations or safety standards in place.

The production of modern pharmaceuticals is strictly regulated to ensure that medicines contain a standardized quantity of active ingredients and are free from contamination. Alternative medicine products are not subject to the same governmental quality control standards, and consistency between doses can vary. This leads to uncertainty in the chemical content and biological activity of individual doses. This lack of oversight means that alternative health products are vulnerable to adulteration and contamination. This problem is magnified by international commerce, since different countries have different types and degrees of regulation. This can make it difficult for consumers to properly evaluate the risks and qualities of given products.

Public use in the US

A botánicas, such as this one in Massachusetts, caters to the Latino community and sells folk medicine alongside statues of saints, candles decorated with prayers, and other items.A 2002 survey of US adults 18 years and older conducted by the National Center for Health Statistics (CDC) and the National Center for Complementary and Alternative Medicine indicated:

74.6% had used some form of complementary and alternative medicine (CAM).
62.1% had done so within the preceding twelve months.
When prayer specifically for health reasons is excluded, these figures fall to 49.8% and 36.0%, respectively.
45.2% had in the last twelve months used prayer for health reasons, either through praying for their own health or through others praying for them.
54.9% used CAM in conjunction with conventional medicine.
14.8% "sought care from a licensed or certified" practitioner, suggesting that "most individuals who use CAM prefer to treat themselves."
Most people used CAM to treat and/or prevent musculoskeletal conditions or other conditions associated with chronic or recurring pain.
"Women were more likely than men to use CAM. The largest sex differential is seen in the use of mind-body therapies including prayer specifically for health reasons".
"Except for the groups of therapies that included prayer specifically for health reasons, use of CAM increased as education levels increased".
The most common CAM therapies used in the US in 2002 were prayer (45.2%), herbalism (18.9%), breathing meditation (11.6%), meditation (7.6%), chiropractic medicine (7.5%), yoga (5.1%), body work (5.0%), diet-based therapy (3.5%), progressive relaxation (3.0%), mega-vitamin therapy (2.8%) and Visualization (2.1%)
In the state of Texas, physicians may be partially protected from charges of unprofessional conduct or failure to practice medicine in an acceptable manner, and thus from disciplinary action, when they prescribe alternative medicine in a complementary manner, if board specific practice requirements are satisfied and the therapies utilized do not present "a safety risk for the patient that is unreasonably greater that the conventional treatment for the patient's medical condition."

Definitions and categorizations

There is no clear and consistent definition as to the exact nature of alternative or complementary medicines.[ In a 2005 report entitled Complementary and Alternative Medicine in the United States[15] the Institute of Medicine (IOM) adopted this definition:

"Complementary and Alternative Medicine (CAM) is a broad domain of resources that encompasses health systems, modalities, and practices and their accompanying theories and beliefs, other than those intrinsic to the dominant health system of a particular society or culture in a given historical period. CAM includes such resources perceived by their users as associated with positive health outcomes. Boundaries within CAM and between the CAM domain and the domain of the dominant system are not always sharp or fixed."[15]
Other groups and individuals have offered various definitions and distinguishing characteristics. The National Center for Complementary and Alternative Medicine (NCCAM) defines CAM as "a group of diverse medical and health care systems, practices, and products, that are not currently part of conventional medicine."[10] NCCAM has developed what the IOM calls "[o]ne of the most widely used classification structures"[15] for the branches of complementary and alternative medicine.[10] The Cochrane Complementary Medicine Field says:

"What are considered complementary or alternative practices in one country may be considered conventional medical practices in another. Therefore, our definition is broad and general: complementary medicine includes all such practices and ideas which are outside the domain of conventional medicine in several countries and defined by its users as preventing or treating illness, or promoting health and well-being. These practices complement mainstream medicine by 1) contributing to a common whole, 2) satisfying a demand not met by conventional practices, and 3) diversifying the conceptual framework of medicine."[16]
David M. Eisenberg defines it as "medical interventions not taught widely at US medical schools or generally available at US. hospitals,"[17] while Richard Dawkins sardonically defines it as a "set of practices which cannot be tested, refuse to be tested, or consistently fail tests."[18]

The term "alternative medicine" is generally used to describe practices used independently or in place of conventional medicine. The term "complementary medicine" is primarily used to describe practices used in conjunction with or to complement conventional medical treatments. NCCAM suggests "using aromatherapy therapy in which the scent of essential oils from flowers, herbs, and trees is inhaled in an attempt to promote health and well-being and to help lessen a patient's discomfort following surgery" as an example of complementary medicine. The terms "integrative" or "integrated medicine" indicate combinations of conventional and alternative medical treatments which have some scientific proof of efficacy; such practices are viewed by advocates as the best examples of complementary medicine. Ralph Snyderman and Andrew Weil go so far as to claim that "integrative medicine is not synonymous with complementary and alternative medicine. It has a far larger meaning and mission in that it calls for restoration of the focus of medicine on health and healing and emphasizes the centrality of the patient-physician relationship." The combination of orthodox and complementary medicine with an emphasis on prevention and lifestyle changes is known as integrated medicine.

Nutrition and Exercise

The updated USDA food pyramid, published in 2005, is a general nutrition guide for recommended food consumption.Nutrition is the science that studies how people eat affects their health and performance, such as foods or food components that cause diseases or deteriorate health (such as eating too many calories, which is a major contributing factor to obesity, diabetes, and heart disease). The field of nutrition also studies foods and dietary supplements that improve performance, promote health, and cure or prevent disease, such as eating fibrous foods to reduce the risk of colon cancer, or supplementing with vitamin C to strengthen teeth and gums and to improve the immune system.

Personal health depends partially on the social structure of one’s life. The maintenance of strong social relationships is linked to good health conditions, longevity, productivity, and a positive attitude. This is due to the fact that positive social interaction as viewed by the participant increases many chemical levels in the brain which are linked to personality and intelligence traits. Essentially this means that positive reinforcement from a third party make one more socially adept, in control, and relaxed physically and mentally, all of which are proven to affect the nervous system (UHF).


Sports nutrition
Main article: Sports nutrition
Sports nutrition focuses the link between dietary supplements and athletic performance. One goal of sports nutrition is to maintain glycogen levels and prevent glycogen depletion. Another is to optimize energy levels and muscle tone. An athlete's strategy for winning an event may include a schedule for the entire season of what to eat, when to eat it, and in what precise quantities (before, during, after, and between workouts and events). Participants in endurance sports such as the full-distance triathlon actually eat during their races. Sports nutrition works hand-in-hand with sports medicine.


Exercise

A U.S. Marine emerges from the water upon completing the swimming leg of a triathlon.Exercise is the performance of movements in order to develop or maintain physical fitness and overall health. It is often directed toward also honing athletic ability or skill. Frequent and regular physical exercise is an important component to prevention of some of the diseases of affluence such as cancer, heart disease, cardiovascular disease, Type 2 diabetes, obesity and back pain.

Exercises are generally grouped into three types depending on the overall effect they have on the human body:

Flexibility exercises such as stretching improve the range of motion of muscles and joints.
Aerobic exercises such as walking and running focus on increasing cardiovascular endurance and muscle density.
Anaerobic exercises such as weight training or sprinting increase muscle mass and strength.
Physical exercise is considered important for maintaining physical fitness including healthy weight; building and maintaining healthy bones, muscles, and joints; promoting physiological well-being; reducing surgical risks; and strengthening the immune system.

Proper nutrition is just as, if not more, important to health as exercise. When exercising it becomes even more important to have good diet to ensure the body has the correct ratio of macronutrients whilst providing ample micronutrients; this is to aid the body with the recovery process following strenuous exercise. When the body falls short of proper nutrition, it gets into starvation mode developed through evolution and depends onto fat content for survival. Research suggest that the production of thyroid hormones can be negatively affected by repeated bouts of dieting and calorie restriction. Proper rest and recovery is also as important to health as exercise, otherwise the body exists in a permanently injured state and will not improve or adapt adequately to the exercise.

The above two factors can be compromised by psychological compulsions (eating disorders such as exercise bulimia, anorexia, and other bulimias), misinformation, a lack of organization, or a lack of motivation. These all lead to a decreased state of health.

Delayed Onset Muscle Soreness can occur after any exercise, particularly if the body is in an unconditioned state relative to that exercise and the exercise involves repetitive eccentric contractions.

Mental health

The treatment of mental disorders dates back to ancient civilisations, including Ancient Egypt, India, Greece and Rome. Medieval physicians in the Muslim world from the 8th to 15th centuries were concerned with mental health.

In the mid-19th century, William Sweetzer was the first to clearly define the term "mental hygiene". Isaac Ray, one of thirteen founders of the American Psychiatric Association, further defined mental hygiene as an art to preserve the mind against incidents and influences which would inhibit or destroy its energy, quality or development.

At the beginning of the 20th century, Clifford Whittingham Beers founded the National Committee for Mental Hygiene and opened the first outpatient mental health clinic in the United States.

Mental health can be seen as a continuum, where an individual's mental health may have many different possible values. Mental wellness is generally viewed as a positive attribute, such that a person can reach enhanced levels of mental health, even if they do not have any diagnosable mental health condition. This definition of mental health highlights emotional well-being, the capacity to live a full and creative life, and the flexibility to deal with life's inevitable challenges. Many therapeutic systems and self-help books offer methods and philosophies espousing strategies and techniques vaunted as effective for further improving the mental wellness of otherwise healthy people. Positive psychology is increasingly prominent in mental health.

A holistic model of mental health generally includes concepts based upon anthropological, educational, psychological, religious and sociological perspectives, as well as theoretical perspectives from personality, social, clinical, health and developmental psychology.

An example of a wellness model includes one developed by Myers, Sweeny and Witmer. It includes five life tasks — essence or spirituality, work and leisure, friendship, love and self-direction—and twelve sub tasks—sense of worth, sense of control, realistic beliefs, emotional awareness and coping, problem solving and creativity, sense of humor, nutrition, exercise, self care, stress management, gender identity, and cultural identity—are identified as characteristics of healthy functioning and a major component of wellness. The components provide a means of responding to the circumstances of life in a manner that promotes healthy functioning. Most of the US Population is not educated on Mental Health.


[edit] Lack of a mental disorder
See also: Mental disorder
Mental health can also be defined as an absence of a major mental health condition though recent evidence stemming from positive psychology (see above) suggests mental health is more than the mere absence of a mental disorder or illness. Therefore the impact of social, cultural, physical and education can all affect someone's mental health.


[edit] Cultural and religious considerations
Mental health can be socially constructed and socially defined; that is, different professions, communities, societies and cultures have very different ways of conceptualizing its nature and causes, determining what is mentally healthy, and deciding what interventions are appropriate. Thus, different professionals will have different cultural and religious backgrounds and experiences, which may impact the methodology applied during treatment.

Many mental health professionals are beginning to, or already understand, the importance of competency in religious diversity and spirituality. The American Psychological Association explicitly states that religion must be respected. Education in spiritual and religious matters is also required by the American Psychiatric Association.


[edit] Mental health profession
Main article: Mental health professional
A number of professions have developed specializing in mental disorders, including the medical speciality of psychiatry, divisions of psychology known as clinical psychology, abnormal psychology, positive psychology, applied behavior analysis, behavior therapy, clinical or mental health social work, mental health counselors, marriage and family therapists, psychotherapists, counselors and public Health professionals. Different clinical and academic professions tend to favor differing models, explanations and goals.

Stress management

Historical foundations
Walter Cannon and Hans Selye used animal studies to establish the earliest scientific basis for the study of stress. They measured the physiological responses of animals to external pressures, such as heat and cold, prolonged restraint, and surgical procedures, then extrapolated from these studies to human beings.

Subsequent studies of stress in humans by Richard Rahe and others established the view that stress is caused by distinct, measureable life stressors, and further, that these life stressors can be ranked by the median degree of stress they produce (leading to the Holmes and Rahe Stress Scale). Thus, stress was traditionally conceptualized to be a result of external insults beyond the control of those experiencing the stress. More recently, however, it has been argued that external circumstances do not have any intrinsic capacity to produce stress, but instead their effect is mediated by the individual's perceptions, capacities, and understanding.


Models of stress management

Transactional model
Richard Lazarus and Susan Folkman suggested in 1984 that stress can be thought of as resulting from an “imbalance between demands and resources” or as occurring when “pressure exceeds one's perceived ability to cope”. Stress management was developed and premised on the idea that stress is not a direct response to a stressor but rather one's resources and ability to cope mediate the stress response and are amenable to change, thus allowing stress to be controllable.

In order to develop an effective stress management programme it is first necessary to identify the factors that are central to a person controlling his/her stress, and to identify the intervention methods which effectively target these factors. Lazarus and Folkman's interpretation of stress focuses on the transaction between people and their external environment (known as the Transactional Model). The model conceptualizes stress as a result of how a stressor is appraised and how a person appraises his/her resources to cope with the stressor. The model breaks the stressor-stress link by proposing that if stressors are perceived as positive or challenging rather than a threat, and if the stressed person is confident that he/she possesses adequate rather than deficient coping strategies, stress may not necessarily follow the presence of a potential stressor. The model proposes that stress can be reduced by helping stressed people change their perceptions of stressors, providing them with strategies to help them cope and improving their confidence in their ability to do so.


Health realization/innate health model
The health realization/innate health model of stress is also founded on the idea that stress does not necessarily follow the presence of a potential stressor. Instead of focusing on the individual's appraisal of so-called stressors in relation to his or her own coping skills (as the transactional model does), the health realization model focuses on the nature of thought, stating that it is ultimately a person's thought processes that determine the response to potentially stressful external circumstances. In this model, stress results from appraising oneself and one's circumstances through a mental filter of insecurity and negativity, whereas a feeling of well-being results from approaching the world with a "quiet mind," "inner wisdom," and "common sense".

This model proposes that helping stressed individuals understand the nature of thought--especially providing them with the ability to recognize when they are in the grip of insecure thinking, disengage from it, and access natural positive feelings--will reduce their stress.
