Obesity is an important risk factor for cardiometabolic diseases, including diabetes,
hypertension, dyslipidemia, and coronary heart disease (CHD).
Standard Method for identifying patients at increased risk of adiposity-related adverse health outcomes. Body fat distribution is also an important risk factor for obesity-related diseases. Excess abdominal fat (also knownas central or upper-body fat) is associated with an increasedrisk of cardiometabolic disease. However, precise measure-ment of abdominal fat content requires the use of expensive radiological imaging techniques. Therefore, waist circum-ference (WC) is often used as a surrogate marker of abdominal fat mass, because WC correlates with abdominal fatmass (subcutaneous and intra abdominal) and is associ-ated with cardiometabolic disease risk. Men and womenwho have WCs greater than 40 inches (102 cm) and 35inches (88 cm), respectively, are considered to be at in-creased risk for cardiometabolic disease.
You can use a measurement called a body mass index, or BMI, along with your waist size, to decide whether your weight is dangerous to your health. The BMI is a combination of your height and weight. If you have a BMI of 30 or higher, unhealthy eating patterns, and too little physical activity, your extra weight is putting your health in danger.
Use the Interactive Tool: Is Your BMI Increasing Your Health Risks? to find out your body mass index.
Use the Interactive Tool: What Is Your Child’s BMI? to check BMI in children ages 2 to 19.
People who carry too much fat around the middle, rather than around the hips, are more likely to have health problems. In women, a waist size of 88 cm (35 in.) or more raises the chance for disease. In men, a waist size of 102 cm (40 in.) or more raises the chance for disease. Waist size cutoff may be lower for some people.
What Is BMI?
Body Mass Index (BMI) is a mathematical calculation involving height and weight, irrespective of family history, gender, age or race. BMI is calculated by dividing a person’s body weight in kilograms by their height in meters squared (weight [kg] height [m]2) or by using the conversion with pounds (lbs) and inches (in) squared as shown below, This number can be misleading, however, for very muscular people, or for pregnant or lactating women. [Weight (lbs) ÷ height (in)2 ] x 704.5 =BMI
The BMI cutoffs are:
Below 18.5 Underweight
18.5-24.9 Normal weight
30 and greater Obese
40 and greater Morbid or extreme obesity
BMI is frequently used in population studies because of its ease of determination and well-supported association with mortality and health effects. However, other measures of excess adipose tissue, such as waist circumference, waist-to-hip ratio and others are also used. Individuals may need to use additional factors to assess their individual risk including family history, level of physical activity, smoking and dietary habits.
Obesity as a major public health and economic problem has risen to the top of policy and programme agendas in many countries, with prevention of childhood obesity providing a particularly compelling mandate for action. There is widespread agreement that action is needed urgently, that it should be comprehensive and sustained, and that it should be evidence‐based. While policy and programme funding decisions are inevitably subject to a variety of historical, social, and political influences, a framework for defining their evidence base is needed, “Prevent nation from child obesity “.
