Purpose: To examine the relationship between social participation and sense of coherence (SOC) in middle-aged community-dwelling adults.
Methods: In this cross-sectional study, questionnaires were mailed to 2,000 men and women aged 40-64 years randomly selected from residents of Akiruno city, Tokyo. Valid responses were received from 200 men and 300 women. Questions covered SOC, social participation(as indicated by membership of 12 organizations related to such interests as sports, hobbies, and volunteer work), and basic demographic data. The number of groups participated in at least once monthly was used as an index of social participation. ANCOVA was performed to assess the relationship between this social participation variable and SOC.
Results: Among men, 122 (61.0%) did not participate in any social groups, 56 (28.0%) participated in 1 group, and 22 (11.0%) participated in 2 or more groups. Among women, 174 (58.0%) did not participate in any social groups, 83 (27.7%) in 1 group, and 43 (14.3%) in 2 or more groups. The most common type of group for participation among both men and women was sports-related. Social participation and SOC were not associated in men (F=0.56, p=0.57), but were significantly associated in women (F=5.54, p<0.01). Estimated mean SOC in women was 14.7 points, 15.3 points, and 16.3 points for those participating in 0, 1, and 2 or more groups, respectively, showing a tendency toward higher SOC in those participating in more groups.
Conclusion: Among middle-aged community-dwelling adults, SOC was associated with the number of groups memberships, as a measure of social participation, in women only. Overall, SOC tended to be higher among those participating in more groups.
