Abstract

BACKGROUND Innovative methods are warranted to optimize prenatal outcomes. This study's objective was to determine if a web-based behavioral intervention (BI) can prevent excessive gestational weight gain (GWG) by increasing physical activity (PA). METHODS Participants were randomized to usual care (UC; n = 21) or BI (n = 24) between 10 to 14 weeks gestation. GWG, PA, and diet were assessed at baseline, mid-, and late pregnancy. RESULTS No differences in GWG or adherence to GWG recommendations presented between groups. Total UC MET-minutes significantly decreased from baseline to late-pregnancy (1,234 ± 372 MET-minutes, P = .013). Mid-pregnancy sustained PA was greater for BI than UC (20-minute PA bouts: 122 ± 106 vs. 46 ± 48 minutes/week, P = .005; 30-minute PA bouts: 74 ± 70 vs. 14 ± 24 minutes/week, P < .001), and greater for BI at mid-pregnancy compared with baseline (20-minute PA bouts: 61.3 ± 21.9; 30-minute PA bouts: 39.6 ± 14.8, both P < .05). BI energy intake at mid-pregnancy significantly increased from baseline (336 ± 127 kcals, P = .04) and was significantly greater than UC (2,503 ± 703 vs. 1,894 ± 594, P = .005). CONCLUSIONS Sedentary pregnant women should increase PA but may need additional dietary counseling to prevent excessive GWG.

基于网络的行为干预增加了母亲的运动，但不能预防以前久坐不动的妇女妊娠期体重过度增加。

背景创新的方法是必要的，以优化产前结果。本研究的目的是确定基于网络的行为干预(BI)是否可以通过增加身体活动(PA)来预防妊娠期体重过度增加(GWG)。方法参与者随机分为常规护理组(UC;n = 21)或BI (n = 24)在妊娠10 ~ 14周。GWG、PA和饮食在基线、妊娠中期和妊娠晚期进行评估。结果两组间GWG及对GWG建议的依从性无差异。从基线到妊娠后期，UC总MET-minutes显著减少(1,234±372 MET-minutes, P = 0.013)。妊娠中期持续PA的BI大于UC(20分钟PA: 122±106 vs 46±48分钟/周，P = 0.005;30分钟PA次数:74±70 vs. 14±24分钟/周，P < 0.001)，妊娠中期BI与基线相比更高(20分钟PA次数:61.3±21.9;30分钟PA次数:39.6±14.8次，P均< 0.05)。妊娠中期BI组能量摄入较基线显著增加(336±127 kcal, P = 0.04)，且显著高于UC组(2503±703 vs. 1894±594,P = 0.005)。结论久坐孕妇应增加PA，但可能需要额外的饮食咨询以防止GWG过量。

期刊介绍： The Journal of Physical Activity and Health (JPAH) publishes original research and review papers examining the relationship between physical activity and health, studying physical activity as an exposure as well as an outcome. As an exposure, the journal publishes articles examining how physical activity influences all aspects of health. As an outcome, the journal invites papers that examine the behavioral, community, and environmental interventions that may affect physical activity on an individual and/or population basis. The JPAH is an interdisciplinary journal published for researchers in fields of chronic disease.
