近 50% 的美国女性在怀孕时患有超重或肥胖 (OW/OB)。迫切需要了解如何激励 OW/OB 孕妇进行锻炼行为，以改善她们的健康并减少不良妊娠结局。旨在检查正常体重 (NW) 和 OW/OB 孕妇整个怀孕期间运动行为 (EXB) 的计划行为理论信念预测因素。孕妇 (N = 357) 自我报告了她们在怀孕三个月期间的运动信念和行为。皮尔逊相关性用于检查运动信念与行为的关联。使用逐步回归来分别确定每个体重状态组的TRI 2 和TRI 3 EXB 的妊娠期(TRI) 1 和TRI 2 信念预测因子。检查信念认可以确定关键信念。 TRI 1 EXB 信念解释了 TRI 2 EXB 中总方差的 58%（22% NW，36% OW/OB）。 TRI 2 EXB 信念解释了 TRI 3 EXB 中总方差的 32%（17% NW，15% OW/OB）。个人信念因体重状况和妊娠期而异。控制信念的支持率最低；使它们成为运动干预的最重要目标。产前运动干预措施应针对具体体重状况，并针对妊娠三个月特有的显着信念/障碍。
Nearly 50% of U.S. women enter pregnancy as overweight or obese (OW/OB). There is a critical need to understand how to motivate OW/OB pregnant women for exercise behavior to improve their health and reduce adverse pregnancy outcomes. To examine salient Theory of Planned Behavior belief predictors of normal weight (NW) and OW/OB pregnant women’s exercise behavior (EXB) across pregnancy. Pregnant women (N = 357) self-reported their exercise beliefs and behavior during each pregnancy trimester. Pearson correlations were used to examine exercise beliefs-behavior associations. Stepwise regressions were used to identify trimester (TRI) 1 and TRI 2 belief predictors of TRI 2 and TRI 3 EXB, respectively, for each weight status group. Belief endorsement was examined to identify critical beliefs. TRI 1 EXB beliefs explained 58% of the total variance (22% NW, 36% OW/OB) in TRI 2 EXB. TRI 2 EXB beliefs explained 32% of the total variance (17% NW, 15% OW/OB) in TRI 3 EXB. Individual beliefs varied by weight status and trimester. Control beliefs emerged with the lowest endorsement; making them most critical to target for exercise interventions. Prenatal exercise interventions should be weight status specific and target salient beliefs/barriers unique to the pregnancy trimesters.
