The Avon Longitudinal Study of Parents and Children (ALSPAC) is an observational study of 14,273 UK pregnant singleton mothers in 1990/1991. We examined outcomes of self report of strenuous activity (hours per week) at 18 and 32 weeks of gestation, hours spent in leisure-time physical activities and types, and pre-pregnancy body mass index (BMI); overweight status was defined as pre-pregnancy BMI≥25 and obesity BMI≥30. Pet ownership and activity data were reported for 11,466 mothers. Twenty-five percent of mothers owned at least one dog. There was a positive relationship between participation in activity at least once a week and dog ownership (at 18 weeks, Odds ratio 1.27, 95% confidence interval 1.11-1.44, P<0.001). Dog owners were 50% more likely to achieve the recommended 3 hours activity per week, equivalent to 30 minutes per day, most days of the week (1.53, 1.35-1.72, P<0.001). Dog owners were also more likely to participate in brisk walking activity than those who did not have a dog (compared to no brisk walking 2-6 hrs per week 1.43, 1.23 to 1.67, P<0.001; 7+ hrs per week 1.80, 1.43 to 2.27, P<0.001). However, no association was found with any other types of activities and there was no association between dog ownership and weight status. During the time period studied, pregnant women who had dogs were more active, through walking, than those who did not own dogs. As walking is a low-risk exercise, participation of pregnant women in dog walking activities may be a useful context to investigate as part of a broader strategy to improve activity levels in pregnant women.
雅芳纵向研究父母与子女（ALSPAC）是一项针对 1990/1991 年英国 14273 名单胎孕妇的观察性研究。我们检查了 18 周和 32 周妊娠时剧烈活动（每周小时数）、休闲时间体育活动时间和类型以及孕前体重指数（BMI）的自我报告结果；超重状态定义为孕前 BMI≥25，肥胖 BMI≥30。宠物拥有和活动数据报告了 11466 位母亲。25%的母亲至少拥有一只狗。每周至少参加一次活动与养狗之间存在正相关关系（在 18 周时，比值比 1.27，95%置信区间 1.11-1.44，P<0.001）。狗主人每周达到建议的 3 小时活动量的可能性增加 50%，相当于每天 30 分钟，每周大部分天数（1.53，1.35-1.72，P<0.001）。与没有狗的人相比，狗主人更有可能进行轻快步行活动（与每周无轻快步行 2-6 小时相比 1.43，1.23-1.67，P<0.001；每周 7 小时以上 1.80，1.43-2.27，P<0.001）。然而，没有发现与任何其他类型的活动有关，也没有发现养狗与体重状况有关。在所研究的时间段内，养狗的孕妇比不养狗的孕妇更活跃，通过散步。由于散步是一种低风险的运动，因此孕妇参与遛狗活动可能是一个有用的背景，可以作为提高孕妇活动水平的更广泛策略的一部分进行调查。
