Background Cardiovascular disease is a major health issue in Hong Kong. We
conducted a screening program to assess the 10-year risk for the population
and to assess the potential benefit of large-scale screening in Hong Kong.
Method A local screening program for cardiovascular risk was carried out in
a health service network with a total of 17716 participants. Retrospective
data analysis for the prevalence and distribution of the various risk fact
ors was performed. The data were then applied to calculate the 10-year risk
of each individual, according to the European Task Force coronary risk cha
rt.
Results Of the participants, 54.2% had total cholesterol levels >5.2 mmol/l
; 28.7% had body mass index >25 kg/m(2); 18.5% were hypertensive; 15.1% wer
e smokers; and 3.7% had diabetes mellitus. There were 35.5% of the screened
population who had at least two risk factors and 10.9% had at least three
risk factors. A total of 9049 individuals satisfied the criteria for the Eu
ropean Task Force guidelines and were selected for 10-year cardiovascular r
isk analysis. We calculated that 68.0% of the male population had at least
10% risk and 41.5% had at least 20% risk of developing a coronary heart eve
nt within 10 years. Among women, 48.2% of the population carried at least 1
0% risk and 2.8% carried at least 20% risk,
Conclusion The calculated 10-year risk of the population, particularly for
men, is significant. Our study demonstrated that mass screening is feasible
, and has the benefit of early identification of high-risk individuals, whi
ch could be a reasonable strategy for cost-effective medicine. (C) 1999 Lip
