Waist measures (waist circumference, waist to height ratio) in conjunction with body mass index appear to be associated with lipid and blood pressure assessments among overweight and obese adolescents, according to a report published Online First by Archives of Pediatrics & Adolescent Medicine, a JAMA Network publication.
Body mass index (BMI) is currently the most commonly used measure of obesity in adolescents, according to background in the study. BMI cannot differentiate between fat and fat-free body mass however, so the authors included additional obesity measures including waist circumference (WC) and waist to height ratio (WHtR; WC divided by height) in relation to BMI to examine the role of waist measures in the lipid and blood pressure assessment of adolescents classified by BMI.
