How is BMI calculated? Discuss the health implications of adolescent overweight and obesity
BMI is calculated by dividing a person's weight (kg) by the square of his or her height (m2). A range of medical and psychosocial complications accompanies overweight among adolescents, including hypertension, dyslipidemia, insulin resistance, type 2 diabetes mellitus, sleep apnea and other hypoventilation disorders, orthopedic problems, hepatic diseases, body image disturbances, and lowered self-esteem. Longitudinal studies of obesity and chronic disease risk among youth suggest an increased risk of morbidity and premature mortality from coronary heart disease, stroke, diabetes, asthma, and hypertension among adults who were overweight or obese during adolescence.
