Abstract
Objectives: To investigate the effects of a prenatal exercise intervention on offspring body weight, body mass index (BMI), and lifestyle variables at 7 years of age.
Methods: Out of 105 physically inactive participants initially randomized to either a physical activity intervention or control group, 80 women and their children (76.2%) participated in this follow-up study. The intervention consisted of intensive physical activity counseling and supervised, group-based moderate-intensity exercise sessions during the second and third trimesters of pregnancy, while the control group received standard prenatal care only. Data were collected via a standardized telephone interview with the mother and included the offspring's body weight and height, physical activity level, sports participation, and adherence to general health recommendations regarding screen time and diet. Differences between groups were examined using two-sided independent sample t-tests or chi-squared tests as appropriate.
Results: Mean BMI was similar in both groups (intervention group: n = 40; control group: n = 40), but the intervention group had fewer children with overweight/obesity (1 vs. 4) and underweight (3 vs. 6) than the control group. There was a nonsignificant trend toward increased physical activity among the offspring of the intervention group compared with the control group. This was reflected in a higher number following guidelines (≥ 60 min of daily moderate-to-vigorous physical activity [MVPA] according to WHO recommendations) (97.5% vs. 87.5%), number of bouts of MVPA per week (6.4 ± 3.8 vs. 5.8 ± 2.3), and daily hours of MVPA in both summer and winter seasons (2.4 ± 1.3 vs. 2.2 ± 1.3 and 1.6 ± 1.0 vs. 1.4 ± 1.0). The intervention group also reported higher rates of active school transportation than the control group (72.5% vs. 57.5%). No differences were observed in sedentary screen time and diet between the groups.
Conclusions: Our results suggest that the intervention may have positively influenced the BMI status and physical activity levels of the offspring.
目的：探讨产前运动干预对子女7岁时体重、体重指数（BMI）和生活方式变量的影响。方法：105名不运动的参与者最初随机分为运动干预组和对照组，其中80名妇女及其子女（76.2%）参加了这项随访研究。干预包括在怀孕的第二和第三个月进行密集的体育活动咨询和监督，以小组为基础的中等强度运动，而对照组只接受标准的产前护理。通过对母亲的标准化电话访谈收集数据，包括后代的体重和身高、身体活动水平、体育参与情况以及对屏幕时间和饮食的一般健康建议的遵守情况。组间差异采用双侧独立样本t检验或卡方检验。结果：两组平均BMI相近（干预组：n = 40，对照组：n = 40），但干预组超重/肥胖儿童（1比4）和体重不足儿童（3比6）少于对照组。与对照组相比，干预组的后代体力活动增加的趋势不显著。这反映在更高的遵循指南的人数（根据世卫组织建议，每日中高强度体力活动[MVPA]≥60分钟）（97.5% vs. 87.5%），每周MVPA次数（6.4±3.8 vs. 5.8±2.3），以及夏季和冬季每日MVPA小时数（2.4±1.3 vs. 2.2±1.3和1.6±1.0 vs. 1.4±1.0）。干预组的主动学校交通率也高于对照组（72.5%比57.5%）。在久坐不动的屏幕时间和饮食方面，两组之间没有观察到差异。结论：我们的研究结果表明，干预可能对后代的BMI状况和身体活动水平产生积极影响。
