![]() ![]() ![]() Optimal WHR differs between sex at birth and ethnicities, according to an older report from 2008 from the World Health Organization (WHO). They can then divide this measurement by the width of their hip at its widest part.įor example, if a person’s waist is 28 inches, and their hips are 36 inches, they will divide 28 by 36, giving a WHR of 0.77. To calculate their WHR, a person should measure around their waist at the narrowest part, usually just above the belly button. For this reason, the WHR is a useful tool for calculating whether a person has a moderate weight and size. The higher the waist measurement in proportion to the hips, the greater this risk. Research has shown that people with a high WHR are more likely to develop CVD and diabetes. A high WHR indicates when an individual has higher levels of visceral fat, the fat in the abdominal cavity that surrounds several major organs. However, it should not be the only measure for an individual to assess whether their weight is ideal.Ī person’s WHR compares their waist size with that of their hips. This inaccuracy may lead to a misdiagnosis or an incorrect assessment of risk factors between individuals.īMI can offer a rough idea of whether or not a person is at a moderate weight, and it is useful for measuring trends in population studies. Studies have shown that at the same BMI, non-Hispanic white, non-Hispanic Black, and Mexican Americans may have significantly different levels of body fat. They can have a high BMI because they have more muscle mass, but this does not mean they weigh too much for their height.Īnother limitation of BMI is that it does not distinguish between people of different ethnicities. For example, high-performance athletes tend to be very fit and have little body fat. While it takes height into consideration, it does not account for factors such as: What is the problem with BMI?īMI is a very simple measurement. The CDC’s BMI charts for children use percentiles that compare measurements with boys and girls of the same age and gender. To calculate a child’s BMI, a person can use the CDC’s calculator for children and teenagers. The Centers for Disease Control and Prevention (CDC) use both age and natal sex in its BMI calculations for people between the ages of 2–19 years. If the weight exceeds the normal weight range, weight loss is good for health, appearance, and life perception.Age is not a factor in BMI for adults, but it is for children. Those who know their normal weight range may undertake necessary preventive measures against conditions related to thinness or excessive weight. Genetic particularities, poor fetal metabolism, low birth weight, bad maternal nutrition, insufficient breastfeeding, low physical activity and wrong diets in childhood may exert detrimental effect upon normal weight range. In children and infants some factors may contribute to aberrations from normal weight range. Deviations from normal weight range may result in hypertension, stroke, heart disease, diabetes, arthritis, and cancer.Īmong the factors that affect normal weight range are disparities between food intake and energy expenditure. Persons beyond the normal weight range have higher risk of problems associated with abnormal weight. Normal weight range values cannot be applied directly to children, teenagers, pregnant women and athletes. There are some particularities for practical application of normal weight range. Increased body weight may result from massive muscular growth such as in bodybuilders. Normal weight range may be lower for Asians and sometimes for women. Slim men are at the top of the normal weight range. Slender women usually are at the lower limit of the normal weight range. Normal weight range is applicable to men and women. For adults the normal weight range is the same in all age groups. ![]()
