Interaction of Harmful Alcohol Use and Tea Consumption on Hyperuricemia Among Han Residents Aged 30–79 in Chongqing, China

OBJECTIVE: The prevalence of hyperuricemia appears to be high worldwide. We aimed to explore the interaction between harmful alcohol use and tea consumption on hyperuricemia. METHODS: This study recruited 22,449 Han residents based on the data from the China Multi-Ethnic Cohort (CMEC) study, Chongqing province, to have a face-to-face electronic questionnaire, physical examination, and clinical laboratory tests. The difference in hyperuricemia between the different populations was compared by the Chi-square test. The interaction between harmful alcohol use and tea consumption was analyzed by the multivariate logistic regression model. RESULTS: Amongst 22,449 participants, the mean age was 51.5±11.8 years, and 46.83% of them were males. The proportion of harmful alcohol use, tea consumption, and harmful alcohol use and tea consumption were 14.01%, 21.01%, and 6.54%, respectively. Multivariate logistic regression showed that the odds ratio (OR) of harmful alcohol use and tea consumption (OR=2.21, 95% CI: 1.58–3.10) was greater than that of harmful alcohol use (OR=1.63, 95% CI:1.17–2.27) and tea consumption (OR=1.34, 95% CI:1.10–1.63). Among males, the results were similar (harmful alcohol use and tea consumption: OR=2.02, 95% CI: 1.43–2.84; harmful alcohol use: OR=1.61, 95% CI: 1.14–2.27; tea consumption: OR=1.28, 95% CI: 1.05–1.57). However, among females, the odds ratio of harmful alcohol use and tea consumption (OR=15.50, 95% CI: 1.36–176.50) was more than 10 times than that of only harmful alcohol use (OR=1.55, 95% CI: 0.42–5.69) or tea consumption (OR=1.22, 95% CI: 0.52–2.82). CONCLUSION: The interaction of harmful alcohol use and tea consumption was a positive risk for hyperuricemia in Han residents aged 30–79 years in China.
