Brief summary

This is an observational study to measure the thickness of artery walls in the neck (intima media thickness IMT) by ultrasound examination in middle-aged subjects with central obesity. The purpose of this study is to obtain local data how common asymptomatic atherosclerosis is, and to investigate the association between Cardiovascular Disease risk factors and intima media thickness (IMT) in the Hong Kong population. Results from this study may enhance the public awareness of asymptomatic atherosclerosis and understand its role in the development of Cardiovascular Disease in Hong Kong.

Design outcomes

Primary

Measure	Time frame
To investigate the prevalence of asymptomatic atherosclerosis by measurement of intima media thickness (IMT) in middle-aged subjects with central obesity in Hong Kong,	during the one single study visit

Secondary

Measure	Time frame
To examine the association between IMT value and cardiovascular disease (CVD) risk factors, and blood lipid and glucose profiles in middle-aged centrally obese subjects in Hong Kong.	During the one single study visit
IMT results to be compared with what being reported in the recent literature on normal Chinese population.	During the one single study visit
