Abstract

A hypothesized benefit of social participation is that it encourages people to be more physically active. However, limited evidence exists on the association between social participation over the life-course and physical activity in midlife. We sought to apply a life-course framework to examine the association of social participation and device measured physical activity in midlife in the UK. We used the 1970 British Birth Cohort Study (BCS70), which includes all people born in Britain during a single week in 1970. Social participation was assessed at ages 16, 30, 34 and 42. Physical activity was measured by accelerometery at age 46, as mean daily step count and time spent in moderate to vigorous physical activity (MVPA). The associations of social participation and physical activity were tested using two different life-course models: the sensitive period model and the accumulation model. Individuals with medium and high participation compared to no social participation over their life-course had higher mean daily step count and MVPA in midlife, supporting the accumulation model. In the sensitive period model, only those that actively participated at age 42 had higher mean daily steps and MVPA compared to those who did not participate. Our study provides empirical evidence on the importance of sustaining social participation at all ages over the life-course rather than at a particular timepoint of someone’s life. If our findings reflect causal effects, interventions to promote social participation throughout the life-course could be an avenue to promote physical activity in middle life.

生命历程中的社会参与和中年体育活动:1970 年英国队列研究 (BCS70) 中的纵向联系
摘要 社会参与的一个假定益处是,它能鼓励人们更加积极地参加体育锻炼。然而,关于生命过程中的社会参与与中年体育锻炼之间关系的证据却很有限。我们试图运用生命历程框架来研究英国中年时期社会参与与设备测量的体育活动之间的关系。我们使用了 1970 年英国出生队列研究(BCS70),该研究包括了 1970 年单周在英国出生的所有人。社会参与情况在 16、30、34 和 42 岁时进行评估。体力活动是在 46 岁时通过加速度计测量的,即平均每日步数和中度至剧烈体力活动时间(MVPA)。采用两种不同的生命历程模型:敏感期模型和累积模型,检验了社会参与与体育锻炼之间的关系。在整个生命过程中,中度和高度参与社会活动的人与没有参与社会活动的人相比,在中年时的平均每日步数和 MVPA 都更高,这支持了积累模型。在敏感期模型中,只有那些在 42 岁时积极参加社交活动的人与未参加社交活动的人相比,平均每日步数和 MVPA 更高。我们的研究提供了实证证据,说明在人的一生中各个年龄段而不是某个特定时间点持续参与社会活动的重要性。如果我们的研究结果反映了因果效应,那么在整个生命过程中促进社会参与的干预措施可能是促进中年期体育锻炼的一个途径。

期刊介绍: The European Journal of Epidemiology, established in 1985, is a peer-reviewed publication that provides a platform for discussions on epidemiology in its broadest sense. It covers various aspects of epidemiologic research and statistical methods. The journal facilitates communication between researchers, educators, and practitioners in epidemiology, including those in clinical and community medicine. Contributions from diverse fields such as public health, preventive medicine, clinical medicine, health economics, and computational biology and data science, in relation to health and disease, are encouraged. While accepting submissions from all over the world, the journal particularly emphasizes European topics relevant to epidemiology. The published articles consist of empirical research findings, developments in methodology, and opinion pieces.
