Purpose This study aimed to examine the relationship between participation in social activity and both, composite and individual measures of physical fitness in community-dwelling older adults.Methods This study was conducted using baseline data from the Sasaguri Genkimon Study (SGS), a longitudinal cohort study conducted in 2011. Participants were 1,365 community-dwelling men and women aged 65 years or above, who did not require certified nursing care and who resided in Sasaguri, a town located east of the Fukuoka metropolitan area. Participation in social activity was assessed by asking participants whether they engaged in any of eight social activities. Physical fitness tests assessed participants' handgrip strength and knee extension strength as measures of muscle strength, and their one-leg standing time, 5-m maximum gait speed, and 5-repetition sit-to-stand rate as measures of their physical performance. Multiple linear regression and logistic regression analyses were conducted to assess the relationship between participation in social activity and each measure of physical fitness, adjusting for sex; age; body mass index; socioeconomic status; solitary living; exercise, habitual drinking and smoking; accelerometer-measured, moderate-to-vigorous physical activity; cognitive function; instrumental activities of daily living; distress; social network; and comorbidities.Results A total of 83.6% of the participants were engaged in at least one social activity. After adjusting for potential confounders, engagement in social activity was positively associated with a higher composite physical fitness score, faster gait speed and 5-repetition sit-to-stand rate, and longer one-leg standing time (P=0.008, P=0.030, P=0.034, and P=0.009, respectively).Conclusion Participation in social activity was significantly associated with physical fitness, specifically those related to locomotive function. These associations were independent of various confounders including socioeconomic status, and comorbidities.
目的 本研究旨在探讨社区居住的老年人参与社会活动与综合及个体身体素质指标之间的关系。
方法 本研究使用了笹栗健康调查（SGS）的基线数据，这是一项于2011年进行的纵向队列研究。参与者为1365名居住在社区的65岁及以上男性和女性，他们不需要认证护理，居住在福冈都会区以东的笹栗镇。通过询问参与者是否参与八项社会活动中的任何一项来评估社会活动参与情况。身体素质测试评估了参与者的握力和膝关节伸展力量作为肌肉力量的指标，以及他们的单腿站立时间、5米最大步速和5次坐立重复率作为身体表现的指标。进行了多元线性回归和逻辑回归分析，以评估社会活动参与与各项身体素质指标之间的关系，并对性别、年龄、体重指数、社会经济地位、独居、运动、习惯性饮酒和吸烟、加速度计测量的中度至剧烈身体活动、认知功能、日常生活工具性活动、痛苦、社会网络和合并症进行了调整。
结果 共有83.6%的参与者参与了至少一项社会活动。在对潜在混杂因素进行调整后，参与社会活动与更高的综合身体素质得分、更快的步速和5次坐立重复率以及更长的单腿站立时间呈正相关（分别为P = 0.008、P = 0.030、P = 0.034和P = 0.009）。
结论 参与社会活动与身体素质显著相关，特别是与运动功能相关的身体素质。这些关联独立于包括社会经济地位和合并症在内的各种混杂因素。
