Topical Area: Dietary Bioactive Components
Objectives : We aimed to investigate the associations between tea consumption and CVD risk factors in Chinese patients with T2D.
In a community-based cross-sectional study, 7866 subjects aged 31 to 89 years were recruited between 2011 and 2013 in Suzhou, China. Among these, 1061 subjects with T2D (492 men and 569 women; defined according to the criteria of the American Diabetes Association) who were free of major CVD were included in the present study. Data on dietary habits including tea consumption were collected using a food frequency questionnaire. Multivariate logistic regression model was used to illustrate the associations between tea consumption and CVD risk factors.
Results : After the adjustment for potential confounders, participants with higher frequency of tea drinking (≥2 times/d), as compared with those who never or hardly drank tea, had significantly higher risk of dyslipidemia (OR=1.826, 95% CI: 1.084-3.076) and non-alcoholic fatty liver disease (OR=1.971, 95% CI: 1.051-3.700). No significant association was found between the frequency of tea consumption and obesity, hypertension, metabolic syndrome or hyperuricemia.
Conclusions : Frequent consumption of tea is associated with altered CVD risk factors including dyslipidemia and increased risk of NAFLD among Chinese T2D patients. Further prospective studies are needed to confirm the associations.
