Excess weight during pregnancy increases risk for adverse obstetrical outcomes. Physical activity (PA) may buffer these effects, although it is unclear what factors are associated with PA in women who begin pregnancy with overweight/obesity. The present study sought to characterize the demographic and psychological correlates of PA among women with prepregnancy overweight/obesity.
Pregnant women (N = 249; mean age, 28.48 ± 5.48 years; mean body mass index, 34.13 ± 7.07 kg/m) at 12-20 weeks of gestation (mean, 15.68 ± 2.44 weeks of gestation) completed ratings of perceived stress and depressive symptoms and were interviewed using the pregnancy version of the Eating Disorders Examination. The Paffenbarger Physical Activity Survey was administered via interview to estimate energy expenditure. Continuous outcomes were evaluated via linear regression, while logistic regression was conducted to assess likelihood of meeting PA guidelines.
Mean weekly duration of moderate to vigorous PA was 109.50 ± 248.17 minutes, with 21% of women meeting federal PA guidelines of 150 minutes or more. Higher perceived stress (β = -0.217; p = .02) and eating psychopathology (β = -0.213; p < .01) were associated with lower total energy expenditure. Black women reported lower expenditure specifically from walking compared with White women (β = -0.180; p = .03). Depressive symptoms were not associated with PA. No estimate of PA predicted body mass index.
Pregnant women with overweight/obesity engage in modest amounts of PA early in pregnancy, although few meet PA guidelines. Greater perceived stress and eating psychopathology were associated with lower PA engagement. These factors should be monitored by obstetrics providers to identify women who may particularly benefit from counseling about PA during pregnancy.
孕期体重增加会增加不良产科结局的风险。身体活动（PA）可能会缓冲这些影响，但目前尚不清楚哪些因素与孕前超重/肥胖的女性的 PA 相关。本研究旨在描述孕前超重/肥胖孕妇 PA 的人口统计学和心理学相关性。
在妊娠 12-20 周（平均 15.68±2.44 周）时，249 名孕妇（平均年龄 28.48±5.48 岁；平均体重指数 34.13±7.07kg/m²）完成了感知压力和抑郁症状的评分，并接受了妊娠版饮食障碍检查的访谈。通过访谈进行了 Paffenbarger 体力活动调查，以估计能量消耗。连续结果通过线性回归进行评估，而逻辑回归用于评估符合 PA 指南的可能性。
中等至剧烈 PA 的每周平均持续时间为 109.50±248.17 分钟，21%的女性符合联邦 PA 指南的 150 分钟或以上。较高的感知压力（β=-0.217；p=0.02）和饮食心理病理学（β=-0.213；p<0.01）与总能量消耗较低相关。与白人女性相比，黑人女性报告的步行支出较低（β=-0.180；p=0.03）。抑郁症状与 PA 无关。PA 估计值与体重指数无关。
孕前超重/肥胖的孕妇在妊娠早期就进行了适度的 PA，但很少符合 PA 指南。较高的感知压力和饮食心理病理学与较低的 PA 参与度相关。这些因素应由产科医生监测，以确定可能特别受益于妊娠期间 PA 咨询的女性。
