Research suggests that physical activity may influence sleep, yet more research is needed before it can be considered a frontline treatment for insomnia. Less is known about how this relationship is moderated by age. Using multilevel modeling, we examined self-reported physical activity and insomnia symptoms in 18,078 respondents from the U.S. nationally representative Health and Retirement Study (2004-2014). The mean baseline age was 64.7 years, with 53.9% female. Individuals who reported more physical activity (B = -0.005, p < .001) had fewer insomnia symptoms. Over 10 years, the respondents reported fewer insomnia symptoms at times when they reported more physical activity than was average for them (B = -0.003, p < .001). Age moderated this relationship (B = 0.0002, p < .01). Although modest, these findings concur with the literature, suggesting moderate benefits of physical activity for sleep in older adults. Future research should aim to further elucidate this relationship among adults at advanced ages.
研究表明,体育活动可能会影响睡眠,但在其被视为失眠的一线治疗方法之前,还需要更多的研究。关于年龄如何调节这种关系,我们所知甚少。我们使用多层次模型,对来自美国具有全国代表性的健康与退休研究(2004 - 2014年)的18,078名受访者的自我报告的体育活动和失眠症状进行了研究。平均基线年龄为64.7岁,女性占53.9%。报告体育活动较多的个体(B = -0.005,p < .001)失眠症状较少。在10年期间,当受访者报告的体育活动量高于其平均水平时,他们报告的失眠症状较少(B = -0.003,p < .001)。年龄调节了这种关系(B = 0.0002,p < .01)。尽管作用不大,但这些发现与文献一致,表明体育活动对老年人的睡眠有适度益处。未来的研究应旨在进一步阐明高龄成年人之间的这种关系。
