Sex education, also known as sexual education, sexualityeducation or sex ed, is the instruction of issues relating to human sexuality, including human sexual anatomy, sexual activity, sexual reproduction, safe sex, and birth control, sexual health, reproductive health, emotional relations and responsibilities, age of consent, and reproductive rights. Sex education that includes all of these issues is known as comprehensive sexuality education. In contrast, abstinence-only sex education, which focuses solely on promoting sexual abstinence, is often favored in more socially conservative regions, including some parts of the United States. Sex education may be provided as part of school programs, public health campaigns, or by parents or caregivers. In some countries it is known as "Relationships and Sexual Health Education".
Physical education, often abbreviated to Phys. Ed. or PE, and sometimes informally referred to as gym class or simply just gym, is a subject taught in schools around the world. PE is taught during primary and secondary education and encourages psychomotor, cognitive, and effective learning through physical activity and movement exploration to promote health and physical fitness. When taught correctly and in a positive manner, children and teens can receive a storm of health benefits. These include reduced metabolic disease risk, improved cardiorespiratory fitness, and better mental health. In addition, PE classes can produce positive effects on students' behavior and academic performance. Research has shown that there is a positive correlation between brain development and exercising. Researchers in 2007 found a profound gain in English Arts standardized test scores among students who had 56 hours of physical education in a year, compared to those who had 28 hours of physical education a year.
Health education is a profession of educating people about health. Areas within this profession encompass environmental health, physical health, social health, emotional health, intellectual health, and spiritual health, as well as sexual and reproductive health education. It can also be defined as any combination of learning activities that aim to assist individuals and communities improve their health by expanding knowledge or altering attitudes.
Childhood obesity is a condition where excess body fat negatively affects a child's health or well-being. As methods to determine body fat directly are difficult, the diagnosis of obesity is often based on BMI. Due to the rising prevalence of obesity in children and its many adverse health effects it is being recognized as a serious public health concern. The term overweight rather than obese is often used when discussing childhood obesity, as it is less stigmatizing, although the term overweight can also refer to a different BMI category. The prevalence of childhood obesity is known to differ by sex and gender.
Comprehensive sex education (CSE) is an instructional approach aimed at providing individuals, particularly young people, with accurate, holistic information about sexuality, relationships, and reproductive health. Unlike abstinence-only education, CSE includes a broad curriculum that covers topics such as safe sex practices, contraception, sexually transmitted infections (STIs), sexual orientation, gender identity, and relationship skills. This approach seeks to empower individuals to make informed, responsible decisions regarding their sexual health and to promote respect and equality in sexual relationships.
Peer Health Exchange is a 501(c)(3) health education organization based in Oakland, California. The organization trains college student volunteers to teach skills-based health education in public high schools in low-income communities that lack comprehensive health education. The vision of Peer Health Exchange is that, one day, all teens will have the knowledge and skills to make healthy decisions, advancing health equity for teens in under-resourced communities.
Obesity is common in the United States and is a major health issue associated with numerous diseases, specifically an increased risk of certain types of cancer, coronary artery disease, type 2 diabetes, stroke, and cardiovascular disease, as well as significant increases in early mortality and economic costs.
Based in Washington, D.C., Leadership for Healthy Communities is a $10-million national program of the Robert Wood Johnson Foundation designed to engage and support local and state government leaders nationwide in their efforts to advance public policies that support healthier communities and prevent childhood obesity. The program places an emphasis on policies with the greatest potential for increasing sustainable opportunities for physical activity and healthy eating among children at highest risk for obesity, including African-American, Latino, American Indian and Alaska Native, Asian-American and Pacific Islander children living in lower-income communities. The foundation's primary goal is the reversal of the childhood obesity epidemic by 2015.
In the United States, sex education is taught in two main forms: comprehensive sex education and abstinence-only as part of the Adolescent Family Life Act, or AFLA. Comprehensive sex education is also called abstinence-based, abstinence-plus, abstinence-plus-risk-reduction, and sexual risk reduction sex education. This approach covers abstinence as a choice option, but also informs adolescents about age of consent and the availability of contraception and techniques to avoid contraction of sexually transmitted infections. Every state within the U.S. has a mandated AIDS Education Program.
Lack of physical education is the inadequacy of the provision and effectiveness of exercise and physical activity within modern education.
Let's Move! was a public health campaign in the United States led by former First Lady Michelle Obama. The campaign aimed to reduce childhood obesity and encourage a healthy lifestyle in children.
Obesity in the Middle East and North Africa is a notable health issue. Out of the 15 fattest nations in the world as of 2014, according to the World Health Organization (WHO), five were located in the Middle East and North Africa region.
Nutrition education is a combination of learning experiences designed to teach individuals or groups about the principles of a balanced diet, the importance of various nutrients, how to make healthy food choices, and how both dietary and exercise habits can affect overall well-being. It includes a combination of educational strategies, accompanied by environmental supports, designed to facilitate voluntary adoption of food choices and other nutrition-related behaviors conducive to well-being. Nutrition education is delivered through multiple venues and involves activities at the individual, community, and policy levels. Nutrition Education also critically looks at issues such as food security, food literacy, and food sustainability.
Eat Smart, Move More, Weigh Less is a 15-week adult weight management program that uses strategies based on evidence for weight loss and/or weight maintenance. The Eat Smart Move More Weigh Less classes focus on the 12 evidence-based eating and physical activity behaviors for weight management. The program does not provide a prescriptive diet plan, it teaches small lifetime changes. The program teaches mindfulness as a strategy to become more aware of eating and physical activity. Eat Smart, Move More, Weigh Less includes methods for planning and tracking healthy eating and physical activity behaviors. In 2007, Eat Smart, Move More, Weigh Less curriculum was developed by a writing team from North Carolina State University and North Carolina Division of Public Health. A complete listing of authors and their respective affiliations can be found on the program website. The 15-lesson curriculum was peer reviewed by state and local nutrition and physical activity professionals, representatives from the medical community, and a CDC project officer.
In the United States, school meals are provided either at no cost or at a government-subsidized price, to students from low-income families. These free or subsidized meals have the potential to increase household food security, which can improve children's health and expand their educational opportunities. A study of a free school meal program in the United States found that providing free meals to elementary and middle school children in areas characterized by high food insecurity led to increased school discipline among the students.
Childhood obesity is defined as a body mass index (BMI) at or above the 96th percentile for children of the same age and sex. It can cause a variety of health problems, including high blood pressure, high cholesterol, heart disease, diabetes, breathing problems, sleeping problems, and joint problems later in life. Children who are obese are at a greater risk for social and psychological problems as well, such as peer victimization, increased levels of aggression, and low self-esteem. Many environmental and social factors have been shown to correlate with childhood obesity, and researchers are attempting to use this knowledge to help prevent and treat the condition. When implemented early, certain forms of behavioral and psychological treatment can help children regain and/or maintain a healthy weight.
Obesity and the environment aims to look at the different environmental factors that researchers worldwide have determined cause and perpetuate obesity. Obesity is a condition in which a person's weight is higher than what is considered healthy for their height, and is the leading cause of preventable death worldwide. Obesity can result from several factors such as poor nutritional choices, overeating, genetics, culture, and metabolism. Many diseases and health complications are associated with obesity. Worldwide, the rates of obesity have nearly tripled since 1975, leading health professionals to label the condition as a modern epidemic in most parts of the world. Current worldwide population estimates of obese adults are near 13%; overweight adults total approximately 39%.
Obesity medicine is a field of medicine dedicated to the comprehensive treatment of patients with obesity. Obesity medicine takes into account the multi-factorial etiology of obesity in which behavior, development, environment, epigenetic, genetic, nutrition, physiology, and psychosocial contributors all play a role. As time progresses, we become more knowledgeable about the complexity of obesity, and we have ascertained that there is a certain skill set and knowledge base that is required to treat this patient population. Clinicians in the field should understand how a myriad of factors contribute to obesity including: gut microbiota diversity, regulation of food intake and energy balance through enteroendocrine and neuroregulation, and adipokine physiology. Obesity medicine physicians should be skilled in identifying factors which have contributed to obesity and know how to employ methods to treat obesity. No two people with obesity are alike, and it is important to approach each patient as an individual to determine which factors contributed to their obesity in order to effectively treat each patient. Physicians specializing in obesity medicine may choose to obtain board certification by the American Board of Obesity Medicine.
