Organized Social Activity, Physical Exercise, and the Risk of Insomnia Symptoms Among Community-Dwelling Older Adults

Objectives: To compare the risk of insomnia symptoms among community-dwelling older adults who participated and did not participate in organized social activity and physical exercise. Design: Secondary data analysis of a prospective cohort study. Material and Methods: Community-dwelling older adults ≥65 years of age with no insomnia symptoms at baseline were included in the study. Participants were followed up yearly for 3 years. Insomnia symptoms, social activity, and physical exercise status of study participants were assessed at baseline and during follow-up. Results: Study participants who reported engaging in organized social activity and low-intensity physical exercise and organized social activity and high-intensity physical exercise were less likely to report insomnia symptoms during follow-up compared with those who did not engage in any activity. Conclusion: These results suggest beneficial effect of organized social activity and physical exercise in maintaining sleep quality in old age.
