In order to examine the association between pre-pregnancy leisure time physical activities and gestational weight gain, postpartum weight gain and birth weight, we analysed prospectively collected data from 1827 women with singleton term pregnancies. Women were categorised in groups of sedentary women, light exercisers, moderate exercisers and competitive athletes. The results showed that sedentary women on average gained 14.1 kg during pregnancy, whereas light exercisers gained 13.7 kg, moderate exercisers gained 14.3 kg and competitive athletes 16.1 kg. Competitive athletes had an increased risk of having a gestational weight gain above Institute of Medicine (IOM) recommendations with an odds ratio of 2.60 (1.32-5.15) compared to light exercisers. However, birth weight and one year postpartum weight was similar for all four groups. Thus, although competitive athletes gain more weight than recommended during pregnancy, this may not affect birth weight or postpartum weight. Impact statement What is already known on this subjectPrevious studies have found that increased pre-pregnancy physical activity is associated with lower gestational weight gain during the last trimester, but showed no association between the pre-pregnancy level of physical activity and mean birth weight. What the results of this study addWe found that women classified as competitive exercisers had a 2.6-fold increased risk of gaining more weight than recommended compared to light exercisers. Nearly 6 out of 10 women among the competitive exercisers gained more weight than recommended by IOM. Surprisingly, this did not appear to increase birth weight or post-partum weight gain, but other adverse effects cannot be excluded. What the implications are of these findings for clinical practice and/or further researchIn the clinical practice it may be relevant to focus on and advise pre-pregnancy competitive exercisers in order to prevent excessive gestational weight gain.
为了研究孕前休闲时间的体育活动与孕期体重增加、产后体重增加及出生体重之间的关联，我们对前瞻性收集的1827名单胎足月妊娠女性的数据进行了分析。女性被分为久坐不动的女性、轻度运动者、中度运动者和竞技运动员组。结果显示，久坐不动的女性孕期平均增重14.1千克，而轻度运动者增重13.7千克，中度运动者增重14.3千克，竞技运动员增重16.1千克。与轻度运动者相比，竞技运动员孕期体重增加超过医学研究所（IOM）建议的风险增加，优势比为2.60（1.32 - 5.15）。然而，四组的出生体重和产后一年体重相似。因此，尽管竞技运动员在孕期体重增加超过建议值，但这可能不会影响出生体重或产后体重。影响声明关于该主题已知的信息先前的研究发现，孕前体育活动增加与孕晚期较低的孕期体重增加有关，但孕前体育活动水平与平均出生体重之间无关联。本研究的结果补充了什么我们发现，与轻度运动者相比，被归类为竞技运动者的女性体重增加超过建议值的风险增加了2.6倍。竞技运动者中近十分之六的女性体重增加超过了IOM的建议值。令人惊讶的是，这似乎并未增加出生体重或产后体重增加，但不能排除其他不良影响。这些发现对临床实践和/或进一步研究的意义在临床实践中，关注并建议孕前竞技运动者以预防孕期体重过度增加可能是有意义的。
