Body mass index (BMI) is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m2, resulting from mass in kilograms (kg) and height in metres (m).
Obesity is a medical condition, sometimes considered a disease, in which excess body fat has accumulated to such an extent that it can potentially have negative effects on health. People are classified as obese when their body mass index (BMI)—a person's mass divided by the square of the person's height—is over 30 kg/m2; the range 25–30 kg/m2 is defined as overweight. Some East Asian countries use lower values to calculate obesity. Obesity is a major cause of disability and is correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis.
Marasmus is a form of severe malnutrition characterized by energy deficiency. It can occur in anyone with severe malnutrition but usually occurs in children. Body weight is reduced to less than 62% of the normal (expected) body weight for the age. Marasmus occurrence increases prior to age 1, whereas kwashiorkor occurrence increases after 18 months. It can be distinguished from kwashiorkor in that kwashiorkor is protein deficiency with adequate energy intake whereas marasmus is inadequate energy intake in all forms, including protein. This clear-cut separation of marasmus and kwashiorkor is however not always clinically evident as kwashiorkor is often seen in a context of insufficient caloric intake, and mixed clinical pictures, called marasmic kwashiorkor, are possible. Protein wasting in kwashiorkor generally leads to edema and ascites, while muscular wasting and loss of subcutaneous fat are the main clinical signs of marasmus, which makes the ribs and joints protrude.
A chronic condition is a health condition or disease that is persistent or otherwise long-lasting in its effects or a disease that comes with time. The term chronic is often applied when the course of the disease lasts for more than three months. Common chronic diseases include diabetes, functional gastrointestinal disorder, eczema, arthritis, asthma, chronic obstructive pulmonary disease, autoimmune diseases, genetic disorders and some viral diseases such as hepatitis C and acquired immunodeficiency syndrome. An illness which is lifelong because it ends in death is a terminal illness. It is possible and not unexpected for an illness to change in definition from terminal to chronic. Diabetes and HIV for example were once terminal yet are now considered chronic due to the availability of insulin for diabetics and daily drug treatment for individuals with HIV which allow these individuals to live while managing symptoms.
A non-communicable disease (NCD) is a disease that is not transmissible directly from one person to another. NCDs include Parkinson's disease, autoimmune diseases, strokes, heart diseases, cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Alzheimer's disease, cataracts, and others. NCDs may be chronic or acute. Most are non-infectious, although there are some non-communicable infectious diseases, such as parasitic diseases in which the parasite's life cycle does not include direct host-to-host transmission.
Malaysia is classified by The World Bank as upper middle-income country and is attempting to achieve high-income status by 2020 and to move further up the value-added production chain by attracting investments in high technology, knowledge-based industries and services. Malaysia's HDI value for 2015 was recorded at 0.789 and HDI rank no 59 out of 188 countries and territories on the United Nations Development Programme's Human Development Index. In 2016, the population of Malaysia is 31 million; Total expenditure on health per capita is 1040; Total expenditure on health as % of GDP (2014) was 4.2. Gross national income (GNI) per capita was recorded at 24,620.
Health in Ethiopia has improved markedly since the early 2000s, with government leadership playing a key role in mobilizing resources and ensuring that they are used effectively. A central feature of the sector is the priority given to the Health Extension Programme, which delivers cost-effective basic services that enhance equity and provide care to millions of women, men and children. The development and delivery of the Health Extension Program, and its lasting success, is an example of how a low-income country can still improve access to health services with creativity and dedication.
Chronic, non-communicable diseases account for an estimated 80% of total deaths and 70% of disability-adjusted life years (DALYs) lost in China. Cardiovascular diseases, chronic respiratory disease, and cancer are the leading causes of both death and of the burden of disease, and exposure to risk factors is high: more than 300 million men smoke cigarettes and 160 million adults are hypertensive, most of whom are not being treated. An obesity epidemic is imminent, with more than 20% of children aged 7–17 years in big cities now overweight or obese. Rates of death from chronic disease in middle-aged people are higher in China than in some high-income countries.
Being overweight is having more body fat than is optimally healthy. Being overweight is especially common where food supplies are plentiful and lifestyles are sedentary.
Obesity has been observed throughout human history. Many early depictions of the human form in art and sculpture appear obese. However, it was not until the 20th century that obesity became common — so much so that, in 1997, the World Health Organization (WHO) formally recognized obesity as a global epidemic and estimated that the worldwide prevalence of obesity has nearly tripled since 1975. Obesity is defined as having a body mass index (BMI) greater than or equal to 30 kg/m2, and in June 2013 the American Medical Association classified it as a disease.
Obesity in pets occurs when excessive adipose tissue accumulates in the body, and is generally defined as occurring when an animal's body weight is at least 20% greater than its optimal body weight. Obesity is associated with metabolic and hormonal changes, and can predispose pets to illnesses like orthopedic disease, diabetes, and cancer.
Pacific island nations and associated states make up the top seven on a 2007 list of heaviest countries, and eight of the top ten. In all these cases, more than 70% of citizens aged 15 and over are obese. A mitigating argument is that the BMI measures used to appraise obesity in Caucasian bodies may need to be adjusted for appraising obesity in Polynesian bodies, which typically have larger bone and muscle mass than Caucasian bodies; however, this would not account for the drastically higher rates of cardiovascular disease and type 2 diabetes among these same islanders.
Obesity classification is a ranking of obesity, the medical condition in which excess body fat has accumulated to the extent that it has an adverse effect on health. The World Health Organization (WHO) classifies obesity by body mass index (BMI). BMI is further evaluated in terms of fat distribution via the waist–hip ratio and total cardiovascular risk factors. In children, a healthy weight varies with sex and age, and obesity determination is in relation to a historical normal group.
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.
The waist-to-height ratio is the waist circumference divided by body height, both measured in the same units.
Below are two tables which report the average adult human height by country or geographical region. With regard to the first table, original studies and sources should be consulted for details on methodology and the exact populations measured, surveyed, or considered. With regard to the second table, these estimated figures for adult human height for said countries and territories in 2019 and the declared sources may conflict with the findings of the first table.
The Broselow Tape, also called the Broselow pediatric emergency tape, is a color-coded length-based tape measure that is used throughout the world for pediatric emergencies. The Broselow Tape relates a child's height as measured by the tape to their weight to provide medical instructions including medication dosages, the size of the equipment that should be used, and the level of energy when using a defibrillator. Particular to children is the need to calculate all these therapies for each child individually. In an emergency, the time required to do this detracts from valuable time needed to evaluate, initiate, and monitor patient treatment. The Broselow Tape is designed for children up to approximately 12 years of age who have a maximum weight of roughly 36 kg (79 lb). The Broselow Tape is recognized in most medical textbooks and publications as a standard for the emergency treatment of children.
Preventive Nutrition is a branch of nutrition science with the goal of preventing, delaying, and/or reducing the impacts of disease and disease-related complications. It is concerned with a high level of personal well-being, disease prevention, and diagnosis of recurring health problems or symptoms of discomfort which are often precursors to health issues. The overweight and obese population numbers have increased over the last 40 years and numerous chronic diseases are associated with obesity. Preventive nutrition may assist in prolonging the onset of non-communicable diseases and may allow adults to experience more "healthy living years." There are various ways of educating the public about preventive nutrition. Information regarding preventive nutrition is often communicated through public health forums, government programs and policies, or nutritional education. For example, in the United States, preventive nutrition is taught to the public through the use of the food pyramid or MyPlate initiatives.
Obesity in Thailand has been flagged as a major source of health concern, with 32% of the population identifying as overweight and 9% obese. With reference to 2016 data from the World Health Organization (WHO), Thailand has one of the highest incidence of overweight citizens in the South East Asian region, second to only Malaysia. The Thai National Health Examination Surveys (NHES) found that obesity in Thailand more than doubled during the period 1991-2014. This spike in obesity levels has been largely attributed to increased access to junk food, and unhealthy switches from active to sedentary lifestyles. These factors are closely linked to economic growth in the country.
According to the World Health Organization (2015), the "worldwide population of overweight and obese adults increased between 1980 and 2013 from 30 percent to 38 percent in women, and 29 percent to 37 percent in men". The prevalence of obesity continues to rise in all age groups in this developing country.
