Abstract

OBJECTIVE

To examine whether dog ownership amongst community dwelling older adults (≥ 65 years) is associated with objectively measured physical activity (PA).

METHODS

We used data from the Physical Activity Cohort Scotland (PACS) which consists of 547 people aged 65 and over, resident in the community in Tayside, Scotland. The data was collected in 2009-2011. We assessed whether dog ownership is associated with objectively measured physical activity (accelerometry counts).

RESULTS

The physical activity (PA) counts of 547 older people (mean age 79 (standard deviation (SD) 8 years, 54% female) were analysed. Linear mixed models showed that dog ownership was positively related to higher PA levels. This positive relationship remained after controlling for a large number of individual and contextual variables, including attitude towards exercise, physical activity intention and history of physical activity. Dog owners were found to be 12% more active (21,875 counts, 95% Confidence Interval (CI): 2810 to 40,939, p<0.05) than non-dog owners.

CONCLUSION

Dog ownership is associated with physical activity in later life. Interventions to increase activity amongst older people might usefully attempt to replicate elements of the dog ownership experience.

摘要

目的

研究社区居住的老年人（≥65岁）养狗是否与客观测量的身体活动（PA）相关。

方法

我们使用了苏格兰身体活动队列研究（PACS）的数据，该研究包括547名年龄在65岁及以上、居住在苏格兰泰赛德社区的居民。数据于2009 - 2011年收集。我们评估了养狗是否与客观测量的身体活动（加速度计计数）相关。

结果

分析了547名老年人的身体活动（PA）计数（平均年龄79岁（标准差（SD）8岁，54%为女性））。线性混合模型显示，养狗与较高的PA水平呈正相关。在控制了大量个体和背景变量后，这种正相关关系依然存在，这些变量包括对运动的态度、身体活动意图和身体活动史。发现养狗者比不养狗者的活动量多12%（21,875次计数，95%置信区间（CI）：2810至40,939，p<0.05）。
