A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The trial is a small, single-blind, two-group randomized design to assess feasibility and the immediate and 3-month follow-up effects of a blended Baduanjin exercise plus green tea program versus no treatment. Participants are older adults with depressive symptoms recruited from community settings in Hong Kong and randomly assigned to either the blended intervention or a non-treatment control. Assessments occur at baseline, after 12 weeks, and at a 3-month post-intervention point, with outcome assessors blinded to group assignment. Primary aims are feasibility outcomes and changes in depressive symptoms, with exploratory endpoints including gut microbiota composition and quality of life. The study uses a smartphone-enabled delivery framework and local community centers for implementation.
