Prevalence of Clustering for Current Smoking,Current Drinking and Components of Metabolic Syndrome among Adults of Lanxi, Heilongjiang,China

Abstract

A total of 2967 participants were surveyed in a poor county of Heilongjiang by a stratified randomized cluster sampling. Information on CVD risk factors was collected with standardized questionnaires and Laboratory Measurements during 2006 to 2007.Overall, 93.65%, 73.71%, 46.29%, 21.55% and 6.99% of rural residents had 1; 2; 3; 4 and 5 modifiable CVD risk factors (serum triglycerides(TG), high density lipoprotein cholesterol(HDL-C), hypertension, diabetes, current smoking, current drinking and overweight. Both hypertension prevalence and diabetes prevalence increased with age, but HDL-C prevalence decreased with age among both men and women (each P for trend, < 0:001).TG, current drinking and current smoking prevalence decreased with age (each P for trend, < 0:05, except for overweight and MS, each P for trend, > 0:05) Among men. While, TG, current drinking, current smoking and MS prevalence increased with age (each P for trend, < 0:001) among women. In a multivariate model including age and sex, the odds ratio (95% confidence interval [CI]) of having 1; 2; 3; 4, and 5 CVD risk factors versus none of the studied risk factors were 3.15(95%CI, 1.92-5.16), 3.73(95%CI, 2.27-6.13), 4.31(95%CI,2.59-7.17), 5.24(95% CI, 3.04-9.03), and 9.29(95% CI, 4.78-18.06), respectively,for Chinese adults 65 to 74 years old versus 35 to 44 years old; 1.77(95%CI, 1.28-2.45), 1.98(95%CI, 1.42-2.74), 2.39(95%CI, 1.70-3.35), 2.40(95% CI, 1.66-3.74),and 2.79(95% CI, 1.77-4.40), respectively, for men compared with women.
