Changes in Satisfaction with Meaningful Activities and Onset of Depressive Symptoms among Community-Dwelling Japanese Older Adults: A Population-Based Study Before and During the COVID-19 Pandemic

OBJECTIVES: This study aimed to clarify the association between changes in satisfaction with meaningful activities and the occurrence of depressive symptoms before and during the coronavirus disease 2019 (COVID-19) pandemic. DESIGN: A population-based prospective cohort study (Tarumizu Study). SETTING AND PARTICIPANTS: A total of 231 community-dwelling older adults aged ≥65 years without depressive symptoms at baseline. METHODS: The participants completed baseline (June to December 2018, before the COVID-19 pandemic) and follow-up (September to December 2021, during the COVID-19 pandemic) assessments. Depressive symptoms were assessed using the 15-item Geriatric Depression Scale (GDS-15) and defined by a GDS-15 score of ≥5. Participants selected meaningful activities from the 95 activities included in the Aid for Decision-Making in Occupation Choice, and their satisfaction levels were evaluated. Satisfaction with the most meaningful activities was assessed as to whether it was maintained/improved or decreased at follow-up. RESULTS: In the follow-up survey, 31 (14.3%) participants reported the occurrence of depressive symptoms. Compared with before the COVID-19 pandemic, the rates of meaningful activities during the COVID-19 pandemic decreased for interpersonal interaction and social life and increased for leisure, sports, self-care, and domestic life. Logistic regression analysis revealed that changes in satisfaction with meaningful activity were associated with the occurrence of depressive symptoms after adjusting for demographic variables, baseline GDS scores, cognitive and physical status, and instrumental activities of daily living (odds ratio, 2.78; 95% confidence interval, 1.17–6.59, P = .020). CONCLUSIONS AND IMPLICATIONS: To avoid decreasing satisfaction with meaningful activities, supporting older adults may be protective against the occurrence of depressive symptoms. Our findings highlight the need for health care professionals to not only encourage older adults to participate in activities for their mental health but also consider whether the activities are meaningful or satisfying for them.
