![]() In addition, male and female children have differences in body fat distribution, within a range of normal body shapes and sizes. ![]() We know that children are constantly growing, and do so at different rates. It is puts people in weight categories such as underweight, overweight, and obesity. This number serves as a quick estimate of body fat. In simple terms, a person's Body Mass Index or BMI is a calculated measurement of someone's weight in relation to their height. But what does it mean, and why is it important to your child's health? Read on for information about how BMI is calculated, what ranges pediatricians like to see in children, and why BMI-while an important screening measurement of health-can have limitations. You may hear the term body mass index or "BMI" during your child's checkups, or even at your own health visits. "Bioelectric Impedance Analysis in Body Composition Measurement.". "National Health and Nutrition Examination Survey." July 17, 2019. Centers for Disease Control and Prevention. "Lifestyle, Diabetes, and Cardiovascular Risk Factors 10 Years after Bariatric Surgery." New England Journal of Medicine 351 Dec. "A prospective study of obesity and risk of coronary heart disease in women." N Engl J Med. Journal of Internal Medicine 257.4: 338-345. "Weight change and mortality: the Nord-Trondelag Health Study." They may not be entirely accurate but are generally consistent, so they may be used over time to track one's progress.ĭroyvold, W.B., et al. Inexpensive scales for home use that estimate body fat are now widely available. The methods used at health clubs and weight-loss programs may not be accurate if not done properly. Special equipment is needed that is not found at most medical offices. Men with more than 25% fat and women with more than 32% fat are considered obese.īody fat percentage is difficult to measure accurately, however. Many health professionals agree that percentage of body weight that is fat is a good marker of obesity. What Are More Accurate Ways to Measure Body Fat Percentage? Any value over the 90% percentile for age and gender carries the highest risk. The assessment is made with a tape measure stretched across the widest abdominal girth (usually at or just below the level of the belly button, called the umbilicus). This measurement in a child or adolescent correlates closely with the future risk of developing type 2 diabetes mellitus and related complications of the metabolic syndrome (high blood pressure, abnormal cholesterol or other fat levels, heart attack, stroke, and damage to eyes, heart, and kidneys). This includes women with a waist measurement of greater than 35 inches and men with a waist measurement of greater than 40 inches. People with apple or pot belly shapes, who tend to put on weight around their waist, have a higher risk of obesity-related health problems. Waist measurement is also an important factor. Is Waist Circumference (WC) Useful in Determining Obesity? They are much less helpful than body mass index in identifying risk of health problems related to weight. For one thing, they do not distinguish fat from muscle, water, or bone. The tables do not take into account individual conditions. These tables give general ranges of healthy and unhealthy weights for adults based on their height. Divide this by your height in inches again.The greater your BMI, the higher your risk of developing health problems related to excess weight. Therefore, it is used by many primary care doctors to identify obesity. It can also be calculated for weight in pounds and height in inches.īody mass index is closely related to body fat percentage but is much easier to measure. It is defined as weight in kilograms divided by height in meters squared (kg/m2). People with muscular builds may be classified as obese, even with a low bodyfat percentage and optimum health, simply because the BMI formula uses only two data points.ĭoctors and researchers use the BMI formula to screen for obesity, but not to diagnose it, as the BMI is a relatively blunt instrument. If your results from the calculator aren't in the healthy range, don't worry too much. This BMI calculator allows you to easily screen yourself for obesity or extra, unhealthy weight. The body mass index (BMI) is used to assess your weight relative to your height. View your BMI number at the center of the tool and see where you fall on the obesity chart.īMI values are based on clinical data about averages for these measurements across a wide swath of people.Set the height and weight dials to match your own height and weight.Use the switch on top to pick either metric or imperial measurements.The default BMI of 16.6 shown on the tool is for a 5'5" person who weighs 100 lbs.
