BODY MEASUREMENTS AND CARDIOVASCULAR HEALTH

IN THE HONG KONG ADULT POPULATION

Obesity is an increasing worldwide health problem. Previous studies have shown consistently both absolute total fat and adipose tissue distributions are closely associated with cardiovascular risks such as diabetes, hypertension and hyperlipidemia. Studies have also shown that fat distribution, rather than absolute total fat, was more closely associated with these risk factors, especially insulin resistance and glucose intolerance.

Body mass index (BMI) is the most well known anthropometric measurement on general obesity. Waist-to-hip ratio (WHR) is a simple measurement and is so far the most widely used index of central fat distribution. Another simple measurement, waist circumference (WC), has recently been shown to be related to cardiovascular risks.

This presentation aims to present some observations in the local population the degree of association of central obesity (WHR, WC) and general obesity (BMI) with cardiovascular risks - plasma lipids profiles, glucose, insulin levels, and blood pressure; and to clarify which of the three anthropometric indices are most closely associated with the cardiovascular risk profiles; and to determine if the association varies with gender.

Data based on population-based studies show that all three measurements are good
indicators of cardiovascular risk profile. All are positively associated with the cardiovascular risk
measures but with no clear threshold values. Among the three measurements, WC was the
strongest predictor of cardiovascular risk factors in women even taking into account BMI
measurement.
