Green Tea, Coffee, and Caffeine Consumption Are Inversely Associated with Self-Report Lifetime Depression in the Korean Population.

ABSTRACT: This study investigated the associations of green tea, coffee, and caffeine consumption with self-report lifetime depression in the Korean population using data from the Korean National Health and Nutrition Examination Survey. In total, 9576 participants (3852 men and 5724 women) aged 19 years or older were selected for the present study. Green tea, coffee, and caffeine consumption levels were assessed with a validated food frequency questionnaire. Multivariate logistic regression analysis was used to determine the odds ratios (OR) and 95% confidence intervals (CIs) for depression according to green tea, coffee, and caffeine consumption. Frequent green tea consumers (?3 cups/week) had 21% lower prevalence of depression (OR = 0.79, 95% CI = 0.63?0.99, p for trend = 0.0101) than green tea non-consumers after adjustment for potential confounders. Likewise, frequent coffee drinkers (?2 cups/day) had 32% lower prevalence of depression (OR = 0.68, 95% CI = 0.55?0.85, p for trend = 0.0026) than coffee non-drinkers after adjustment for potential confounders. Also, participants in the highest quartile of caffeine consumption had 24% lower prevalence of depression than those in the lowest quartile (OR = 0.76, 95% CI = 0.62?0.92, p for trend = 0.0032). Frequent consumption of green tea, coffee, or caffeine was associated with a reduced prevalence of self-report lifetime depression in Korean adults. A prospective study and randomized clinical trials should be conducted to confirm the inverse relationships of green tea and coffee consumption with risk of depression.

Project description:Coffee and tea are commonly consumed beverages. Inverse associations with mortality have been suggested for coffee and tea, but the relationships with cause-specific mortality are not well understood. We examined regular and decaffeinated coffee and tea in relation to mortality due to all causes, vascular, nonvascular, and cancer in the multi-ethnic, prospective, population-based Northern Manhattan Study. The study population included 2461 participants with diet data who were free of stroke, myocardial infarction, and cancer at baseline (mean age 68.30 ± 10.23 y, 36% men, 19% white, 23% black, 56% Hispanic). During a mean follow-up of 11 y, we examined the associations between coffee and tea consumption, assessed by food frequency questionnaire, and 863 deaths (342 vascular related and 444 nonvascular including 160 cancer deaths) using multivariable-adjusted Cox models. Coffee consumption was inversely associated with all-cause mortality [for each additional cup/d, HR = 0.93 (95% CI: 0.88, 0.99); P = 0.02]. Caffeinated coffee was inversely associated with all-cause mortality, driven by a strong protection among those who drank ≥4 cups/d. An inverse dose-response relationship between tea and all-cause mortality was suggested [for each additional cup/d, HR = 0.91 (95% CI: 0.84, 0.99); P = 0.01]. Coffee consumption ≥4/d was protective against nonvascular death [vs. <1/mo, HR = 0.57 (95% CI: 0.33, 0.97)] and tea consumption ≥2/d was protective against nonvascular death [HR = 0.63 (95% CI: 0.41, 0.95)] and cancer [HR = 0.33 (95% CI: 0.14, 0.80)]. There was a strong inverse association between coffee and vascular-related mortality among Hispanics only. Further study is needed, including investigation into the mechanisms and compounds in coffee and tea responsible for the inverse associations with mortality. The differential relationship between coffee and vascular death across race/ethnicity underscores the need for research in similar multi-ethnic cohorts including Hispanics.

Project description:Aim The aim of the study was to examine the relationship between coffee, tea, caffeine consumption and risk of all-cause death and cardiovascular disease (CVD) death in CVD population. Methods This cohort study included 626 CVD participants aged ≥18 years old who derived from the National Health and Nutrition Examination Surveys (NHANES) database 2003–2006. The end time of follow-up was 2015, and with a median follow-up time of 113.5 (63, 133) months. CVD death was defined as a death caused by congestive heart failure (CHF), coronary heart disease (CHD), angina pectoris, heart attack or stroke. Cox model and competitive-risk model were used to explore the relationship of coffee, tea, caffeine, decaffeinated coffee/tea on the risk of the all-cause death and CVD death for CVD population, respectively. Additionally, we explored the effect of urinary caffeine and caffeine metabolites on all-cause death. Results All patients were divided into survival group (n = 304), non-CVD death group (n = 223), and CVD death group (n = 99). The incidence of all-cause death and CVD death was ~51.44 and 15.81% in the study. After adjusting age, body mass index (BMI), cancer, estimated glomerular filtration rate (eGFR), energy, the history of CVD medications, carbohydrate and family income to poverty ratio (PIR), the results suggested coffee, caffeine, iced tea and hot tea consumption (≥4 cups per day) were associated with an increased risk of the all-cause death in CVD patients; while hot tea (1–3 cups per day), decaffeinated coffee/iced tea/hot tea could reduce the risk of the all-cause death. Likewise, coffee, caffeine, iced tea (≥4 cups per day), hot tea, decaffeinated iced tea/ hot tea (Always) could enhance the risk of the CVD death in CVD population. We also found that 1-methylxanthine showed a significant positive association on the risk of all-cause death in CVD population. Conclusion Our study indicated that higher consumption of coffee, tea and caffeine could increase the risk of all-cause and CVD death for CVD patients.

Project description:Background and purposeThe effect of green tea and coffee consumption on mortality among cardiovascular diseases survivors is unknown. We examined the association between green tea and coffee consumption and mortality among persons with and without stroke or myocardial infarction (MI).MethodsIn the Japan Collaborative Cohort Study, 46?213 participants (478 stroke survivors, 1214 MI survivors, and 44?521 persons without a history of stroke or MI), aged 40 to 79 years at baseline (1988-1990), completed a lifestyle, diet, and medical history questionnaire and were followed up regarding mortality until 2009. The Cox proportional hazard model was used to calculate the multivariable hazard ratios with 95% CIs of all-cause mortality after adjusting for potential confounding factors.ResultsDuring the 18.5-year median follow-up period, 9253 cases were documented. Green tea consumption was inversely associated with all-cause mortality among stroke or MI survivors; the multivariable hazard ratios (95% CIs) for stroke survivors were 0.73 (0.42-1.27) for 1 to 6 cups/wk, 0.65 (0.36-1.15) for 1 to 2 cups/d, 0.56 (0.34-0.92) for 3 to 4 cups/d, 0.52 (0.31-0.86) for 5 to 6 cups/d, and 0.38 (0.20-0.71) for ?7 cups/d, compared with nondrinkers. A similar inverse association was observed for MI survivors, but not evident for those without a history of stroke or MI. Coffee consumption was inversely associated with all-cause mortality in persons without a history of stroke or MI; the multivariable hazard ratios (95% CIs) were 0.86 (0.82-0.91) for 1 to 6 cups/wk, 0.86 (0.80-0.92) for 1 cup/d, and 0.82 (0.77-0.89) for ?2 cups/d, compared with nondrinkers. The corresponding hazard ratios (95% CIs) for MI survivors were 0.69 (0.53-0.91), 0.78 (0.55-1.10), and 0.61 (0.41-0.90). No such association was observed for stroke survivors.ConclusionsGreen tea consumption can be beneficial in improving the prognosis for stroke or MI survivors, whereas coffee consumption can also be so for persons without a history of stroke or MI as well as MI survivors.
