Although exercising with others might have health benefits, no previous study has comprehensively examined associations of exercise arrangement with physical activity (PA), physical function (PF), and mental health (MH). We examined whether PA, PF, and MH are better when exercising with others than when exercising alone or not exercising.
We analyzed cross-sectional data from 7759 (4007 men and 3752 women) nondisabled residents age 65 to 84 yr. PA, PF, and MH were assessed with the International Physical Activity Questionnaire-Short Form (PA sufficiency defined as ≥150 min·wk of moderate-to-vigorous PA), Motor Fitness Scale (higher PF defined as total score ≥12 in men and ≥10 in women), and World Health Organization-Five Well-Being Index (better MH defined as a total score ≥13), respectively. Exercise arrangement was classified as "nonexerciser," "exercising alone," and "exercising with others." Using multilevel logistic regression analyses, we examined independent associations of exercise arrangement with PA, PF, and MH.
Compared with exercising alone, the multivariate-adjusted odds ratios (95% confidence interval) among nonexercisers and those exercising with others were 0.21 (0.17-0.25) and 1.32 (1.04-1.67), respectively, for PA sufficiency, 0.47 (0.40-0.57) and 1.12 (0.94-1.34) for higher PF, and 0.69 (0.58-0.82) and 1.45 (1.17-1.79) for better MH, respectively, in men. In women, the corresponding odds ratios were 0.37 (0.30-0.46) and 1.31 (1.01-1.70) for PA sufficiency, 0.66 (0.54-0.80) and 1.08 (0.88-1.32) for higher PF, and 0.70 (0.58-0.85) and 1.27 (1.03-1.56) for better MH, respectively.
Exercising alone and with others were better than no exercise for maintaining better PA, PF, and MH in both sexes. Although exercise arrangement had little effect on maintaining PF, exercising with others appears to enhance PA levels and MH in both sexes.
尽管与他人一起锻炼可能会带来健康益处，但之前尚无研究全面评估锻炼安排与身体活动（PA）、身体机能（PF）和心理健康（MH）之间的关系。我们研究了与独自锻炼或不锻炼相比，与他人一起锻炼时 PA、PF 和 MH 是否更好。
我们分析了 7759 名（4007 名男性和 3752 名女性）年龄在 65 至 84 岁之间的非残疾居民的横断面数据。使用国际体力活动问卷-短表（PA 充足定义为≥150 分钟·wk 的中等到剧烈 PA）、运动机能量表（男性总分≥12 分，女性总分≥10 分表示 PF 较高）和世界卫生组织-五维度健康指数（MH 较好定义为总分≥13）分别评估 PA、PF 和 MH。锻炼安排分为“不锻炼者”、“独自锻炼者”和“与他人一起锻炼者”。使用多水平逻辑回归分析，我们研究了锻炼安排与 PA、PF 和 MH 的独立关联。
与独自锻炼相比，不锻炼者和与他人一起锻炼者的多变量调整后比值比（95%置信区间）分别为 0.21（0.17-0.25）和 1.32（1.04-1.67），PA 充足度为 0.47（0.40-0.57）和 1.12（0.94-1.34），PF 较高，0.69（0.58-0.82）和 1.45（1.17-1.79），MH 较好，分别为男性。在女性中，PA 充足度的相应比值比为 0.37（0.30-0.46）和 1.31（1.01-1.70），PF 较高的为 0.66（0.54-0.80）和 1.08（0.88-1.32），MH 较好的为 0.70（0.58-0.85）和 1.27（1.03-1.56）。
与不锻炼相比，独自锻炼和与他人一起锻炼更有利于保持男性和女性更好的 PA、PF 和 MH。尽管锻炼安排对维持 PF 的影响较小，但与他人一起锻炼似乎可以提高两性的 PA 水平和 MH。
