BACKGROUND: Coffee consumption has been shown to be inversely associated to type 2 diabetes mellitus (T2DM), but evidence in Chinese populations is limited. We investigated the relationship between coffee consumption and T2DM in a population-based cohort of middle-aged Chinese. MATERIALS AND METHODS: We studied 2332 subjects who participated in the Taichung Community Health Study in Taiwan in 2004. The relationships between coffee consumption, T2DM and fasting glucose were assessed. RESULTS: The prevalence of T2DM was 14·0% and 10·4% in men and women. After adjustment for age, body mass index, blood pressure, smoking, alcohol drinking, betel nut chewing, physical activity, income, education level, fat%, protein%, carbohydrate% and magnesium, coffee intake was inversely associated with T2DM. Habitual coffee drinkers had 38-46% lower risk of T2DM than nondrinkers. Compared to nondrinkers, the adjusted odds ratios (ORs) for T2DM according to subjects with habitual coffee consumption (<1, 1-6, ≥7 times per week) were 0·77 (0·52-1·13), 0·46 (0·28-0·76) and 0·37 (0·16-0·83), respectively. The decreasing ORs indicate a dose-response effect of coffee consumption on the likelihood of having T2DM (P<0·001). A similar relationship was also evident in newly diagnosed T2DM (P<0·05). The adjusted mean fasting glucose levels gradually decreased as the frequency of coffee consumption increased (P<0·05). CONCLUSIONS: Coffee intake is inversely associated with T2DM in Chinese. Coffee may be a protective agent for T2DM in Chinese.
