Key result
Daily tea consumption was associated with a greater improvement in psychological resilience compared to non-drinkers over a 3-year follow-up (OR 1.176).
Why the study?
The association between tea consumption and dynamic changes in psychological resilience among older adults with chronic diseases was not established.

Yes
Does daily tea consumption improve psychological resilience in older adults with chronic diseases?
Daily tea consumption is associated with improved psychological resilience in older adults, particularly those with cardiometabolic multimorbidity.
Tea intake was associated with resilience gains in multimorbid older adults; leaves open causality and needs randomized confirmation.
Objective: To investigate the association between tea consumption and the dynamic change in psychological resilience (PR) among older adults with chronic diseases. Study design: A prospective cohort study. Methods: A total of 26,454 adults aged 60 and older from the Chinese Longitudinal Healthy Longevity Study were analysed. Tea consumption and PR were evaluated through survey at baseline and at the 3-year follow-up using drinking frequency and a validated scoring scale. Clustering analysis was used to identify multimorbidity clusters. Multivariable analysis was employed to investigate the association between tea consumption and PR change. Several sensitivity analyses were conducted. Results: The sample had an average age of 85.6 ± 12.0 years, with 55.7% female. Ten distinct multimorbidity clusters were identified. Daily tea drinkers exhibited greater improvement in PR (OR=1.176, 95% CI: 1.043-1.327) compared to non-drinkers over a 3-year follow-up. Females (OR=1.362, 95% CI: 1.124-1.649) and participants in the younger-old group (age < 85 years, OR=1.243, 95% CI: 1.075-1.436) were more likely to experience this benefit. This positive association remained significant in participants with multimorbidity (OR=1.437, 95% CI: 1.116-1.850), but not in those considered robust (OR=1.102, 95% CI: 0.931-1.304) or with a single chronic disease (OR=1.117, 95% CI: 0.878-1.421). Specifically, this association was most pronounced within the multimorbidity cluster characterized by cardiometabolic conditions (OR=3.902, 95% CI: 1.081-14.084). The results remained consistent across numerous sensitivity analyses. Conclusions: Daily tea consumption is positively associated with PR improvement among older adults, particularly those with cardiometabolic multimorbidity. Promoting tea drinking habit may represent a viable strategy for promoting active health during late life stages.

Chen et al. (2025) conducted a cohort in chronic diseases (n=26,454). Daily tea consumption vs. Non-drinkers was evaluated on Improvement in psychological resilience (PR) (OR 1.176, 95% CI 1.043-1.327, p=0.008). Daily tea consumption was associated with a greater improvement in psychological resilience compared to non-drinkers over a 3-year follow-up (OR 1.176).
