To examine associations between sustained ownership of a pet and cognitive outcomes among a national sample of U.S. adults. Weighted linear mixed models were estimated using the Health and Retirement Study (2010-2016, = 1369) to compare repeated measures of cognitive function between respondents who endorsed owning a pet in a sustained manner (>5 years), versus those who owned a pet ≤5 years, and non-pet owners. Respondents aged 65+ who owned a pet >5 years demonstrated higher composite cognitive scores, compared to non-pet owners (β = .76, = .03). Sustained pet ownership was associated with higher immediate (β = .3, = .02) and delayed (β = .4, = .007) word recall scores. There were no significant differences in cognitive scores between pet owners and non-owners aged < 65. Sustained ownership of a pet could mitigate cognitive disparities in older adults. Further studies are needed to examine potential causal pathways, including physical activity and stress buffering, versus selection effects.
为了研究美国成年人全国样本中持续拥有宠物与认知结果之间的关联。使用健康与退休研究（2010-2016 年，n=1369）的加权线性混合模型，对在持续时间（>5 年）内支持拥有宠物的受访者与在 5 年内拥有宠物的受访者和非宠物主人之间的认知功能重复测量进行比较。与非宠物主人相比，65 岁以上持续拥有宠物>5 年的受访者的综合认知评分更高（β=0.76，P=0.03）。持续拥有宠物与更高的即时（β=0.3，P=0.02）和延迟（β=0.4，P=0.007）单词回忆得分相关。65 岁以下的宠物主人和非宠物主人之间的认知评分没有显著差异。持续拥有宠物可能会减轻老年人认知差距。需要进一步研究潜在的因果途径，包括身体活动和压力缓冲，与选择效应。
