The aim of the present study was to examine the influence of a supervised and regular program of aquatic activities throughout gestation on maternal weight gain and birth weight.
A randomized clinical trial.
Instituto de Obstetricia, Ginecología y Fertilidad Ghisoni (Buenos Aires, Argentina).
One hundred eleven pregnant women were analyzed (31.6 ± 3.8 years). All women had uncomplicated and singleton pregnancies; 49 were allocated to the exercise group (EG) and 62 to the control group (CG).
The intervention program consisted of 3 weekly sessions of aerobic and resistance aquatic activities from weeks 10 to 12 until weeks 38 to 39 of gestation.
Maternal weight gain, birth weight, and other maternal and fetal outcomes were obtained by hospital records.
Student unpaired t test and χ test were used; P values ≤.05 indicated statistical significance. Cohen's d was used to determinate the effect size.
There was a higher percentage of women with excessive maternal weight gain in the CG (45.2%; n = 28) than in the EG (24.5%; n = 12; odds ratio = 0.39; 95% confidence interval: 0.17-0.89; P = .02). Birth weight and other pregnancy outcomes showed no differences between groups.
Three weekly sessions of water activities throughout pregnancy prevents excessive maternal weight gain and preserves birth weight.

本研究旨在探讨孕期全程有监督的定期水上活动计划对孕妇体重增加和出生体重的影响。
一项随机临床试验。
吉索尼妇产科与生殖研究所（阿根廷布宜诺斯艾利斯）。
对111名孕妇进行了分析（年龄31.6±3.8岁）。所有孕妇均为单胎妊娠且无并发症；49名被分配到运动组（EG），62名被分配到对照组（CG）。
干预计划包括从妊娠第10至12周开始至第38至39周，每周进行3次有氧和抗阻水上活动。
通过医院记录获取孕妇体重增加、出生体重以及其他母婴结局。
采用学生非配对t检验和χ检验；P值≤0.05表示具有统计学意义。使用科恩d值来确定效应大小。
对照组（CG）中孕妇体重增加过多的女性比例（45.2%；n = 28）高于运动组（EG）（24.5%；n = 12；优势比 = 0.39；95%置信区间：0.17 - 0.89；P = 0.02）。两组间出生体重和其他妊娠结局无差异。
孕期每周进行3次水上活动可预防孕妇体重过度增加并维持出生体重。
