与狗一起生活被认为可以增加身体活动。我们测试的假设，成年人生活与犬伴侣有更高水平的身体活动和降低死亡风险相比，那些没有生活在一个伴侣动物。一位联合S.一项全国健康调查，对11，394名年龄在40岁及以上的美国男性和女性进行了纵向死亡率随访，随访时间为1988-1994年，平均随访时间为8.5年。基线测量包括家庭中自我报告的伴侣动物、社会人口统计学、健康状况、身体和生化测量。结果指标为休闲时间体力活动（LTPA）和全因死亡。随访期间死亡3,187人。在双变量横断面分析中，与狗一起生活与更频繁的LTPA和更高的生存率相关。在比例风险回归分析中，没有发现年龄、性别或种族与动物的显著相互作用。在调整了40岁以上的基线社会人口统计学和健康状况的混杂因素后，与犬伴侣生活相比没有动物的风险比（95%置信限）为1.21（1.04-1.41，p < 0.001）。在控制健康行为、血压和体重、C反应蛋白和HDL胆固醇后，HR为1.19（0.97-1.47，NS）。在一个全国性的美国成年人队列中，分析表明，与犬或猫同伴生活在一起的人的死亡风险并不低于混杂因素，尽管犬同伴与LTPA呈正相关。
Living with a canine companion is postulated to increase physical activity. We test the hypotheses that adults living with a canine companion have a higher level of physical activity and reduced mortality risk compared to those not living with a companion animal. A U. S. national health survey with longitudinal mortality follow-up studied 11,394 American men and women aged 40 years and over examined in 1988-1994 followed an average 8.5 years. Measurements at baseline included self-reported companion animals in the household, socio-demographics, health status, physical and biochemical measurements. Outcome measures were leisure-time physical activity (LTPA), and death from all causes. Death during follow-up occurred in 3,187 persons. In bivariate cross-sectional analyses living with a dog was associated with more frequent LTPA and higher survival. In proportional hazards regression analysis, no significant interaction of age, gender or ethnicity with animals was found. After adjusting for confounding by baseline socio-demographics and health status at ages 40+, the hazards ratio (95% confidence limits) for living with a canine companion compared to no animals was 1.21(1.04-1.41, p < 0.001). After also controlling for health behaviors, blood pressure and body mass, C-reactive protein and HDL-cholesterol, the HR was 1.19 (0.97-1.47, NS). In a nationwide cohort of American adults, analyses demonstrated no lower risk of death independent of confounders among those living with canine or feline companions, despite positive association of canine companions with LTPA.
