Body mass index (BMI) is measure of body fat based on height and weight that applies to both adult men and women.
BMI is a reliable indicator of total body fat, which is related to the risk of disease and death. The score is valid for both men and women but it does have some limits. The limits are:
It may overestimate body fat in athletes and others who have a muscular build.
It may underestimate body fat in older persons and others who have lost muscle mass.
Appropriate weight gain during pregnancy varies and depends upon initial body weight or BMI level. Pregnant women should contact a health professional to assure appropriate weight gain during pregnancy.
