Association of green tea consumption with prediabetes, diabetes, and markers of glucose metabolism in rural Vietnam: A cross-sectional study
Br J Nutr. 2024 Feb 16:1-25. doi: 10.1017/S0007114524000412. Online ahead of print.ABSTRACTThe literature on green tea consumption and glucose metabolism has reported conflicting findings. This cross-sectional study examined the association of green tea consumption with abnormal glucose metabolism among 3,000 rural residents aged 40-60 years in Khánh Hòa province in Vietnam. Multinomial logistic regression analysis was conducted to examine the association of green tea consumption (0, < 200, 200-< 400, 400-< 600, or ≥ 600 mL/day) with prediabetes and diabetes (based on the American Diabetes Association criteria). Linear regression analysis was performed to examine the association between green tea consumption and the log-transformed homeostatic model assessment of insulin resistance (HOMA-IR) (a marker of insulin resistance) and the log-transformed homeostatic model assessment of β-cell function (HOMA-β) (a marker of insulin secretion). The odds ratios for prediabetes and diabetes among participants who consumed ≥ 600 mL/day vs. those who did not consume green tea were 1.61 (95% confidence interval (CI) = 1.07-2.42) and 2.04 (95% CI = 1.07-3.89), respectively. Higher green tea consumption was associated with a higher level of log-transformed HOMA-IR (p for trend=0.04) but not with a lower level of log-transformed HOMA-β (p for trend = 0.75). Higher green tea consumption was positively associated with the prevalence of prediabetes, diabetes, and insulin resist...
