Obstetrics & Gynecology:你还认为孕妇不宜活动么?观点该改变了!

传统的观点认为女性在怀孕期间应避免运动以降低早产风险。然而,这种观点已经改变了。现在,一项新的研究指出,怀孕期间进行锻炼是安全的,且母婴均可受益。这项研究发表在Obstetrics & Gynecology。


托马斯杰弗逊大学的Vincenzo Berghella教授指出,既往研究认为锻炼可促使机体释放去甲肾上腺素从而刺激子宫收缩,进而导致早产的发生。他和同事们对9个随机对照研究进行汇总和数据分析。该研究共涉及2059名女性,研究人员将她们随机分为2组:实验组孕妇进行有氧运动,每周3-4次,每次35-90分钟,共持续10周或直至分娩。对照组孕妇不进行有氧运动。 

结果显示两组孕妇早产发生率无明显差异。但实验组阴道分娩的发生率更高(73.6%:67.5%),剖腹产发生率明显降低(17.9%:22%)。此外,研究人员发现实验组孕妇出现妊娠期糖尿病和高血压的发病率明显降低。 就新生儿而言,研究人员没有发现两组新生儿低出生体重儿数量和平均出生体重之间存在差异。 

所有的孕妇均为单胎妊娠,且怀孕起始均为正常体重,也没有影响运动的健康问题。

Berghella教授指出,CDC建议孕妇每周至少进行150分钟中等强度的有氧运动,但是很多孕妇做不到。中等强度的有氧运动包括游泳、快走、日常园艺(如除草或挖掘)。
