Body mass index (BMI) is an estimate of body fat based on height and weight. It doesn’t measure body fat directly, but instead uses an equation to make an approximation. BMI can help determine whether a person is at an unhealthy or healthy weight. A high BMI can be a sign of too much fat on the body, while a low BMI can be a sign of too little fat on the body. The higher a person’s BMI, the greater their chances of developing certain serious conditions, such as heart disease, high blood pressure, and diabetes. A very low BMI can also cause health problems, including bone loss, decreased immune function, and anemia. While BMI can be useful in screening children and adults for body weight problems, it does have its limits. BMI may overestimate the amount of body fat in athletes and other people with very muscular bodies. It may also underestimate the amount of body fat in older adults and other people who have lost muscle mass. BMI is calculated by dividing a person’s weight by the square of their height. The Centers for Disease Control and Prevention (CDC) provides a simple online child and teen BMI calculator for ages 2 to 19, and an adult BMI calculator for ages 20 and older. To calculate the BMI, you enter the height in feet and weight in pounds. The calculators also provide weight status charts to help you interpret the results. BMI is calculated the same way for people of all ages. However, BMI is interpreted differently for adults and children. Adults age 20 and older can interpret their BMI based on the following standard weight status categories. These are the same for men and women of all ages and body types:
BMI is interpreted differently for people under age 20. While the same formula is used to determine BMI for all age groups, the implications for children and adolescents can vary depending on age and gender. The amount of body fat changes with age. It’s also different in young boys and girls. Girls usually acquire a higher amount of body fat and develop it earlier than boys. For children and teens, the CDC uses age growth charts to show BMI as a percentile ranking. Each percentile expresses a child’s BMI relative to other children of the same age and gender. For example, a child would be considered obese if they had a BMI that landed at or above the 95th percentile. This means that they have more body fat than 95 percent of children in the same age and gender category. The following table shows the percentile range for each weight status:
According to the National Institutes of Health, more than two in three adults are considered overweight and one in three are considered obese. About 17 percent of children and teenagers (ages 2 to 19) are considered obese. People gain weight as a result of an energy imbalance. The body needs a certain amount of energy from food in order to function. This energy is obtained in the form of calories. Your weight will usually stay the generally the same when you consume the same number of calories as your body uses or “burns” each day. If you take in more calories than you burn, you will gain weight over time. Energy imbalance is certainly one of the biggest contributors to weight gain. However, your ideal weight is primarily determined by genetics, as well as by the types of foods you eat and how much you exercise. If you have a high BMI, it’s important to lower it so you’re at a healthy weight status. A high BMI is related to a greater risk of developing serious health conditions, such as:
A new study, however, indicates that body fat, not BMI, is more associated with the above health risks. You can lower body fat and get to a healthier weight by exercising at least three times per week. You should also follow certain diet habits, such as eating only when you’re hungry, eating mindfully, and choosing a diet that’s rich in whole, unprocessed foods. You may also benefit from nutritional counseling. A dietitian can teach you which foods to eat and how much food you should eat in order to lose weight. Just as a high BMI can cause health problems, so can a very low BMI. A lack of sufficient body fat may lead to:
If you have a low BMI, discuss your weight with your doctor. If needed, increasing the amount of food you eat each day or reducing the amount of exercise can help you gain weight. A dietitian can also help you learn how to gain weight in a healthy way.
BMI stands for Body Mass Index. It is a measure of body composition. The higher the figure the more overweight you are. Like any of these types of measures it is only a guide, and other issues such as body type and shape have a bearing as well. Remember, BMI is just a guide - it does not accurately apply to elderly populations, pregnant women or very muscular athletes such as weight lifters. BMI is calculated by taking a person's weight and dividing by their height squared. The standard is to use metric units. For instance, if your height is 1.82 meters, the divisor of the calculation will be (1.82 * 1.82) = 3.3124. If your weight is 70.5 kilograms, then your BMI is 21.3 (70.5 / 3.3124). Using pounds and inches, BMI can be calculated by multiplying by a conversion factor of 703, so BMI = weight (lb) / [height (in)]2 x 703 It is easier if you use these calculators.
Test Detailsequipment required: scales and stadiometer required for measuring weight and height. procedure: BMI is calculated from body mass (M) and height (H). BMI = M / (H x H), where M = body mass in kilograms and H = height in meters. The higher the score usually indicating higher levels of body fat. scoring: Generally, a BMI between 20 and 25 is considered normal weight for height, and outside these values is either underweight or overweight. The rating scale is the same for males and females. See the table of BMI Norms based on the World Health Organization BMI classification system. You can also use the reverse lookup BMI table for determining your ideal weight based on height. target population: BMI is often used as a general population measure to determine the level of health risk associated with obesity. advantages: only simple calculations are required from standard height and weight measurements. disadvantages: in certain populations BMI can be inaccurate as a measure of body fatness, for example large and muscular though lean athletes may score high BMI levels which incorrectly rates them as obese. other comments: Other simple measures of body composition, such as skinfolds measures, would be preferable if available.
