This prospective study suggests that frequent green tea consumption is associated with a decreased risk of depressive symptoms in the general Chinese population.
Background: The prospective studies on the effect of particular type of tea consumption, especially green tea, on depressive symptoms are limited. Objective: The aim of this study is to investigate the prospective association between green tea consumption and depressive symptoms in a large general adult population. Methods: This prospective cohort study investigated 7524 participants aged 25 to 90 years from May 2013 to December 2018 and they were free of cardiovascular disease, cancer, and depressive symptoms at baseline. Green tea consumption was obtained through a validated food frequency questionnaire. Depressive symptoms were assessed by using the Self-Rating Depressive Scale (SDS). The association between green tea consumption and depressive symptoms was analyzed by Cox proportional hazards regression models. Results: A total of 1064 first incident cases of depressive symptoms (SDS >= 45) occurred during 14,661 person years of follow-up (median follow-up of 2.0 years). In the crude model, the hazard ratios (95% confidence intervals) were 1.00 (reference), 0.95 (0.81, 1.12), 0.97 (0.83, 1.14) and 0.95 (0.79, 1.14), respectively. After adjusting for demographic characteristics, lifestyle factors, and dietary intake, the multivariable adjusted hazard ratios (95% confidence intervals) were 1.00 (reference), 0.88 (0.74, 1.05), 0.84 (0.69, 1.02) and 0.78 (0.63, 0.97), respectively. Conclusions: The prospective study suggests that frequent green tea consumption is associated with a decreased risk of depressive symptoms in the general Chinese population.
