This cross-sectional study aimed to investigate the association between hyperuricemia and the frequency of coffee, tea, and soft drink consumption, based on data from the Korean Genome and Epidemiology Study (KoGES) (2004–2016). We used the KoGES health examinee data, obtained from urban residents aged ≥ 40 years. Information on the participants’ medical history, nutrition (total calorie, protein, fat, and carbohydrate intake), frequency of alcohol consumption, smoking status, household income, and frequency of coffee/green tea/soft drink intake was collected. A logistic regression model was used to analyze the data. Subgroup analyses were performed according to the participant’s age and sex. Among 173,209 participants, there were 11,750 and 156,002 individuals with hyperuricemia and non-hyperuricemia controls, respectively. In an adjusted model, frequent coffee and green tea consumption did not increase the risk of hyperuricemia, compared to the “no intake” reference group. However, an adjusted odds ratio of hyperuricemia was 1.23 (95% confidence interval, 1.11–1.35, p < 0.001) for participants who reported consuming soft drinks ≥ 3 times per day, compared to the respective “no drink” reference group. Even after adjusting for nutritional and sociodemographic factors, frequent soft drink intake was associated with an increased risk of hyperuricemia. Meanwhile, neither coffee nor green tea intake was associated with an increased risk of hyperuricemia.

ObjectivesTo investigate the association between tea drinking and dysmenorrhoea among women of reproductive age.DesignA cross-sectional study based on Shanghai Birth Cohort Study.SettingTwo preconceptional care clinics in Shanghai, China.Participants1183 women of reproductive age who sought preconceptional care were recruited from August 2013 to April 2015.Primary and secondary outcome measuresParticipants were asked if they had pelvic pain associated with menstrual bleeding during the past 12 months and to further grade the intensity of menstrual cramp as mild, moderate and severe. Multinomial logistic regression was performed to assess the association of tea drinking and dysmenorrhoea. Other information, such as demographic and lifestyle factors, was also collected and assessed in relation to dysmenorrhoea.ResultsThe prevalence of dysmenorrhoea was 57.8%, among whom 10.4% and 3.5% had moderate and severe dysmenorrhoea, respectively. Tea drinking was associated with a lower prevalence of dysmenorrhoea (adjusted OR [aOR]=0.68, 95% CI 0.50 to 0.93 for mild dysmenorrhoea; aOR=0.59 (95% CI 0.32 to 1.04) for moderate-to-severe dysmenorrhoea). Green tea and oolong tea appeared to have most reduction in the prevalence of dysmenorrhoea (for mild dysmenorrhoea: green tea: aOR=0.63 (95% CI 0.44 to 0.90) and oolong tea: aOR=0.60 (95% CI 0.35 to 1.03); for moderate-to-severe dysmenorrhoea: green tea: aOR=0.42 (95% CI 0.20 to 0.85) and oolong tea: aOR=0.34 (95% CI 0.11 to 1.09)).ConclusionsConsumptions of green tea and possibly oolong tea were associated with a lower prevalence of dysmenorrhoea.

Objectives: Several lines of emerging pharmacological and epidemiological evidence imply that overall risks related to COVID-19 may be reduced by green tea catechins. Therefore, it may be expected that: (i) higher green tea consumption is associated with lower COVID-19 morbidity and/or mortality; (ii) countries with higher per/capita green tea consumption would be less affected by COVID-19. The aim of this study was to assess the second possibility. Study design: This was a cross-sectional study. Methods: Among countries with at least 3 million population (n=134), countries with relatively high (above 150 g) per/capita green tea consumption have been tentatively identified (n=21); (ii) normalized to population values of COVID-19 cases (morbidity) and deaths (mortality) for groups of countries with high and low per/capita green tea consumption were compared. Results: Striking differences in COVID-19 morbidity (and mortality) between groups of countries with higher and lower green tea consumption. The differences were still observed after the adjustment for the onset of the disease. Besides, preliminary analysis using multiple linear regression approach suggests that the associations are present at the level of individual countries. Conclusion: Evidence supporting the idea that green tea constituents could reduce overall risks related to COVID-19 has been obtained. The results are promising and are in line with emerging evidence from other studies including pharmacological ones. Nevertheless, because of limitations of this study the idea still should be considered as a hypothesis requiring further assessment.
