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.
