有一些证据表明，养狗可能会改善老年人的身体活动（PA），但到目前为止，研究这一点的研究要么依赖于自我报告，要么依赖于不完整的数据集，因为用于记录身体活动的活动监测器的类型。此外，养狗对久坐行为（SB）的影响尚未探讨。本研究的目的是解决这些问题，通过使用activPAL监测器，以评估狗的所有权对健康的影响，提高PA和SB在独立移动，社区居住的老年人的纵向研究。研究参与者（43对狗主人和非狗主人，在一系列人口统计学变量上匹配）在一年的时间里连续佩戴了三个为期一周的数据收集期。参与者还报告了他们自己和他们的狗的人口统计信息，照顾责任，并完成了唤醒时间的日记。日记数据用于分离清醒时间，以及行走时间、中等步频行走时间（>100步/分钟）、站立时间、坐着时间、坐着事件数量（连续坐着时间）和长时间坐着事件（>30分钟）的数量和时间的结果测量。对于每项测量，使用以狗所有权作为固定效应的线性混合效应模型和嵌套在成对嵌套的参与者中的测量点的随机效应结构来评估狗所有权的影响。养狗表明，在中等强度的步频下，每天额外行走22分钟（95%CI（12，34））和额外行走2760步（95%CI（1667，3991））的平均效应较大，可能改善健康状况。养狗的人坐着的次数明显减少。然而，无论是坐着的总时间，还是长时间久坐的次数或持续时间，两组之间都没有显著差异。在这项研究中发现的狗所有权对PA的影响的规模，表明未来的研究PA在老年人应该评估和报告狗所有权和/或遛狗的状态。本文的在线版本（doi：10.1186/s12889-017-4422-5）包含补充材料，可供授权用户使用。
There is some evidence to suggest that dog ownership may improve physical activity (PA) among older adults, but to date, studies examining this, have either depended on self-report or incomplete datasets due to the type of activity monitor used to record physical activity. Additionally, the effect of dog ownership on sedentary behaviour (SB) has not been explored. The aim of the current study was to address these issues by using activPAL monitors to evaluate the influence of dog ownership on health enhancing PA and SB in a longitudinal study of independently-mobile, community-dwelling older adults. Study participants (43 pairs of dog owners and non-dog owners, matched on a range of demographic variables) wore an activPAL monitor continuously for three, one-week data collection periods over the course of a year. Participants also reported information about their own and their dog demographics, caring responsibilities, and completed a diary of wake times. Diary data was used to isolate waking times, and outcome measures of time spent walking, time spent walking at a moderate cadence (>100 steps/min), time spent standing, time spent sitting, number of sitting events (continuous periods of sitting), and the number of and of time spent sitting in prolonged events (>30 min). For each measure, a linear mixed effects model with dog ownership as a fixed effect, and a random effects structure of measurement point nested in participant nested in pair was used to assess the effect of dog ownership. Owning a dog indicated a large, potentially health improving, average effect of 22 min additional time spent walking, 95%CI (12, 34), and 2760 additional steps per day, 95%CI (1667, 3991), with this additional walking undertaken at a moderate intensity cadence. Dog owners had significantly fewer sitting events. However, there were no significant differences between the groups for either the total time spent sitting, or the number or duration of prolonged sedentary events. The scale of the influence of dog ownership on PA found in this study, indicates that future research regarding PA in older adults should assess and report dog ownership and/or dog walking status.
