Relations between cigarette smoking and chronic diseases of Chinese adults in 2013 / 中华流行病学杂志

ABSTRACT

Objective: To explore the relations between the prevalence of multiple chronic diseases and cigarette smoking behavior in the Chinese adults. Methods: Based on the results: from the 2013 Chronic Disease Risk Factor Surveillance (NCD Surveillance), 176 534 Chinese residents aged 18 years and above, covering 298 counties (districts) in 31 provinces, was randomly recruited, using the multi-stage stratified clustering sampling method. Information on demographics, cigarette smoking (status, quantity and period) was obtained through face-to-face interviews and questionnaires. Anthropometric data and blood samples were collected and properly stored for analysis. Results In total, 175 386 adults were included for statistical analyses, with 42.7% as males and 57.3% as females. The prevalence rates of hypertension, high total cholesterol and high triglycerides were 30.4%, 7.2% and 18.0% in male smokers, 35.6%, 14.0%, 10.3% and 15.9% in female smokers respectively, which were all higher than those in the respective non-smokers. Male smokers were found under lower risk on hypertension, but 19% higher on total glycerides when compared with non-smokers of the same sex(OR=1.19, 95%CI:1.10-1.30), when multiple risk factors were under control. Male current smokers with more than 20 cigarettes per day have 41% (OR=1.41, 95%CI: 1.28-1.55) higher risk of high TG than non-smokers. Female smokers presented 40% (OR=1.40, 95%CI: 1.15-1.70) higher risk in high glycerides than the non-smokers. Specifically, women smoking longer than 20 years have 60% (OR=1.60, 95%CI: 1.31-1.95) higher risk of high TG than women smoking less than 20 years. Conclusions: Prevalence rates of certain chronic diseases were seen higher in smokers of both genders. People with longer history of smoking or being heavier smokers, appeared at advanced risk on developing chronic diseases.
