Sweetened beverages, coffee, and tea and depression risk among older US adults.

Sweetened beverages, coffee, and tea are the most consumed non-alcoholic beverages and may have important health consequences. We prospectively evaluated the consumption of various types of beverages assessed in 1995-1996 in relation to self-reported depression diagnosis after 2000 among 263,923 participants of the NIH-AARP Diet and Health Study. Odds ratios (OR) and 95% confidence intervals (CI) were derived from multivariate logistic regressions. The OR (95% CI) comparing ≥4 cans/cups per day with none were 1.30 (95%CI: 1.17-1.44) for soft drinks, 1.38 (1.15-1.65) for fruit drinks, and 0.91 (0.84-0.98) for coffee (all P for trend
