Association between alcohol consumption and metabolic syndrome among Chinese adults

Objective: To assess the prevalence of metabolic syndrome (MetS) in Chinese adults living in Ningbo and to examine the association between alcohol consumption and MetS and its medical components. Design: A representative survey in Ningbo was conducted in 2015 covering socio-demography. A FFQ together with additional questionnaires was used to collect information on alcohol consumption, diet, demography, lifestyle and medical information. Multivariable logistic regression and generalised linear models were used to examine the association between alcohol consumption and both MetS and its medical components, respectively. Setting: Ningbo, China. Participants: A total of 2853 adults >= 20 years (44 % men) in this final analysis. Results: The prevalence of frequent alcohol drinkers and MetS was 29 center dot 9 % and 28 center dot 0 %, respectively. Significantly higher prevalence of MetS and mean values of medical components were found in the group of frequent alcohol drinkers with an exception for HDL-cholesterol, compared with less or non-alcohol drinkers. Frequent alcohol consumption was associated with higher odds of developing MetS and positively associated with medical components excepting waist circumference. Conclusions: Frequent alcohol consumption contributed to a higher prevalence of MetS and unfavourable influence on MetS and its medical components among Chinese adults. A public health intervention on alcohol restriction is necessary for the prevention and control of the ongoing epidemic MetS.

Automated summary

The study found that the prevalence of frequent alcohol drinkers and MetS among Chinese adults living in Ningbo was 29.9% and 28.0% respectively. There was a positive association between frequent alcohol consumption and MetS and its medical components, highlighting the need for public health interventions to restrict alcohol consumption for the prevention and control of MetS within the population.
