Association of alcohol consumption and components of metabolic syndrome among people in rural China

Association of alcohol consumption and components of metabolic syndrome among people in rural China Previous studies have suggested that moderate alcohol consumption is a protective factor of the metabolic syndrome (MS). However, few studies investigated the relationship between alcohol consumption and components of MS. Researchers examined association of several types of alcoholic beverage with components of MS among people in rural China.

In the Nantong Metabolic Syndrome Study (NMSS), a cross-sectional study, a total of 20,502 participants, including 13,505 women and 6,997 men aged 18-74 years, were recruited between 2007 and 2008 in Nantong, China. Socio-economic status, dietary intake, physical exercise, alcoholic beverage consumption, and smoking status information were obtained, and triglycerides (TG), high-density lipoprotein cholesterol (HDL-c), blood pressure (BP) and blood glucose level were examined for all participants. Logistic regression model and the restricted cubic spline approach were used to analyse the associations between alcoholic beverage consumption and MS components.

The MS prevalence was 21.1% in the whole population, which was significantly lower among drinkers (20.6%), compared with non-drinkers (23.6%) in women, and was comparable in men (16.4% versus 17.1%). Higher ‘good’ cholesterol( HDL-c) levels were observed among drinkers, compared with nondrinkers in both men and women. Low TG level and Systolic BP (SBP) were found only among rice wine drinkers in women, and high waist circumference, high TG and BP were found among beer and liquor drinkers in men.

The data suggested that all alcoholic beverages increased HDL-c level. Rice wine decreased both TG level and blood glucose in women only. Excessive liquor consumption increased blood pressure and waist circumference level and it may lead to hypertension and central obesity in Chinese men, the authors concluded.
