Feasibility and Effects of a Blended Baduanjin Exercise and Green Tea Consumption Program on Depressive Symptoms, Gut Microbiota and Quality of Life in Older Adults
Sponsor: Hong Kong Baptist University
Summary
Depression is a common mental health issue in older adults, often manifesting as insomnia, low mood, vague somatic complaints, cognitive decline, and recurrent thoughts of death or suicide. Even subthreshold depressive symptoms in late life significantly impair quality of life. In Hong Kong, recent data show high prevalence of depressive symptoms among community-dwelling older adults (43.7% in men, 54.8% in women), underscoring the urgent public health and economic need for effective interventions. Although the previous evidence has shown that BDJ and GT consumption can improve depressive symptoms, gut microbiota, and QoL respectively, the feasibility and effect of the combination of two intervention approaches in older adults remain unclear. Therefore, the proposed study aims to (1) determine the feasibility of a 12-week blended BDJ and GT consumption program among Hong Kong community-dwelling older adults with depressive symptoms in a small-scale sample, and (2) examine the effects of the blended BDJ and GT consumption program on their depressive symptoms, gut-microbiota and QoL compared with that in the active control group.

Interventions
blended Baduanjin and Green Tea consumption program
The participants will be invited to attend both BDJ exercise and GT consumption interventions for 12 weeks. The exercise instructor will provide group teaching with individual instructions on specific movements. Participants will also adopt a dose of 3g tea with 200ml water, 2 cups daily. The tea consumption will last 12 weeks in this project to keep the same intervention duration as BDJ group.
Non-treatment control
Participants will receive biweekly telephone calls within 12 weeks.Each call will last about 5 minutes.The participants will be asked several questions about their physical exercise and tea consumption behaviors.
