Objective We investigated the association between dog ownership during the life course and leisure-time PA (LTPA) in late adulthood. Methods We included 714 participants (mean age = 70.8 ± 2.6 years) from the Helsinki Birth Cohort Study (HBCS). Dog ownership for every decade of life, current dog ownership, and current LTPA in metabolic equivalents of task (MET) were assessed with questionnaires. Age and sex adjusted generalized estimating equation models and analysis of regression were applied for the analyses. Results No significant age by dog ownership interaction on total, conditioning or non-conditioning LTPA was found (p ≥ .68). However, after the age of 40 years, dog ownership was increasingly associated with greater total and non-conditioning LTPA in later life. The mean difference in total LTPA, which was mostly explained by non-conditioning LTPA, was largest between the current dog owners and non-owners (15.2 MET-hours/week, 95% CI: 5.5-24.8, p = .002). ConclusionsCurrent dog ownership is associated with 15.2 MET-hours/week greater total LTPA compared to the non-owners. The differences were already observable after the age of 40. Thus, dog ownership induced increase in LTPA can have a positive influence on the aging processes and consequently positively influence healthy active aging.
目的 我们研究了一生中养狗与成年后期休闲时间身体活动（LTPA）之间的关联。方法 我们纳入了来自赫尔辛基出生队列研究（HBCS）的714名参与者（平均年龄 = 70.8 ± 2.6岁）。通过问卷调查评估了每十年的养狗情况、当前的养狗情况以及以代谢当量任务（MET）衡量的当前LTPA。分析采用年龄和性别调整后的广义估计方程模型以及回归分析。结果 在总的、有条件或无条件的LTPA方面，未发现养狗与年龄之间存在显著的交互作用（p≥0.68）。然而，40岁以后，养狗与晚年更高的总LTPA和无条件LTPA越来越相关。当前养狗者与非养狗者之间总LTPA的平均差异最大，主要由无条件LTPA解释（15.2 MET - 小时/周，95%CI：5.5 - 24.8，p = 0.002）。结论 与非养狗者相比，当前养狗与每周总LTPA增加15.2 MET - 小时相关。这种差异在40岁以后就已明显。因此，养狗导致的LTPA增加可能对衰老过程产生积极影响，从而对健康的积极老龄化产生积极影响。
