Abstract Title:
Tea consumption and risk of diabetes in Chinese population: a multi-center, cross-sectional study.
Abstract:
The aim of this study is to explore the influence of tea consumption on diabetes mellitus in Chinese population. This multicenter, cross-sectional study was conducted in eight sites from south, east, north, west and middle regions in China by enrolling 12,017 subjects aged 20-70. Sociodemographic and general information were collected by standardized questionnaire. Standard procedure was used to measure anthropometric characteristics and obtain blood samples. The diagnosis of diabetes was determined using a standard 75-g oral glucose tolerance test. In the final analysis, 10,825 participants were included, and multiple logistic models and interaction effect analysis were applied for assessing the association between tea-drinking with diabetes. Compared with non-tea drinkers, the multivariable-adjusted odds ratios for newly-diagnosed diabetes were 0.80(0.67, 0.97), 0.88(0.71, 1.09) and 0.86(0.67, 1.11) for daily tea-drinkers, occasional tea-drinkers and seldom tea-drinkers, respectively. Furthermore, drinking tea daily was related to decreased risk of diabetes in female by 32%, elderly (>45y) by 24% and obese (BMI>30kg/m2) by 34%. Moreover, drinking dark tea was associated with reduced risk of diabetes by 45% [OR: 0.55 (0.42, 0.72), P
