[Association between drinking and metabolic syndrome among adults in China].

ABSTRACT

OBJECTIVE: To examine the association between alcohol consumption and metabolic syndrome(MS) among Chinese men and women aged 18 years and older. METHODS: The 2010᾿012 China National Nutrition and Health Survey(CNNHS) used multi-stage stratified cluster randomization sampling method to select study participants. Basic information, health-related behaviors and diseases history were collected by questionnaire. Drink information was collected by food frequency questionnaire. Metabolic syndrome was defined according to the updated NCEP ATP III criteria. A total of 102 591 participants aged 18 years and older were included in the analysis. Logistic regression model was performed to examine the association between alcohol consumption and MS. Restricted cubic spline(RCS) was performed to explore the dose response relation of alcohol intake and MS. RESULTS: The drink rate was 33. 66% in Chinese adults aged 18 years and older. Compared with non-drinkers, men who consumed⇿0 g/time had a lower MS prevalence(OR=0. 77, 95%CI 0. 66-0. 90). There was a linear dose response association between alcohol intake and MS among men but not among women. In men, there was no association between drinking type and MS. The OR of MS were 0. 91(95%CI 0. 81-1. 03), 0. 90(95%CI 0. 75-1. 08), 0. 85(95%CI 0. 54-1. 36), and 0. 96(95%CI 0. 84-1. 10) among men who consumed liquor, beer, wine, and mixed liquor. Compared with non-drinkers, women who drink liquor or mixed liquor had a decrease MS prevalence. The OR were 0. 74(95%CI 0. 56-0. 98) and 0. 78(95%CI 0. 66-0. 91). The association between drinking frequency and MS had no statistical significance and the P-trend was 0. 11 in men and 0. 31 in women. CONCLUSION: There is a linear dose response association between alcohol intake and MS among men but not in women. Men consumed >20 g/time have an increased MS prevalence.
