To determine if an association exists between daily physical activity, and pregnancy/neonatal outcomes in stay at home military wives.
This is a prospective observational study of pregnant military wives who do not work outside the home. Participants completed a validated questionnaire of their daily activity from which the average energy expenditure per day (kcal/day) was calculated. Participants were grouped, according to their energy expenditure and assessed for antepartum, intrapartum, and neonatal outcomes.
There were 55 women (group 1) who expended ≤ 2,200 kcal/day, 77 expended 2,201 to 3,000 kcal/day, and 58 expended ≥ 3,001 kcal/day. Group 1 had the lowest maternal weight at first visit (p < 0.001) and delivery (p < 0.001) and highest percentage of primigravidas (p = 0.002). After adjusting for key maternal characteristics, women in group 1 were more likely to develop gestational diabetes. Although not significant, the women in group 1 had more intrauterine growth restriction and preterm labor whereas group 3 had a greater risk of antepartum hemorrhage.
Primigravida women of low weight not working are most likely to use the least energy compared to the heaviest women who use the most calories and are more likely to develop gestational diabetes.
确定居家军属妻子的日常身体活动与妊娠/新生儿结局之间是否存在关联。
这是一项针对不在家工作的怀孕军属妻子的前瞻性观察性研究。参与者完成了一份经过验证的日常活动问卷，据此计算出每日平均能量消耗（千卡/天）。根据能量消耗对参与者进行分组，并评估其产前、产时和新生儿结局。
有55名女性（第1组）每日能量消耗≤2200千卡，77名女性消耗2201至3000千卡，58名女性消耗≥3001千卡。第1组在首次就诊时（p<0.001）和分娩时（p<0.001）的孕妇体重最低，初产妇比例最高（p=0.002）。在对关键的孕产妇特征进行调整后，第1组的女性更易患妊娠期糖尿病。虽然不显著，但第1组的女性有更多的胎儿生长受限和早产情况，而第3组有更大的产前出血风险。
与体重最重、消耗热量最多且更易患妊娠期糖尿病的女性相比，未工作的低体重初产妇女性最有可能能量消耗最少。
