文献概要

●妊娠中の適度な運動は，母体の健康維持・増進につながる．ACOGガイドラインでは，運動禁忌ではない妊婦は，中等度の運動（例えばエアロビクス）を1日あたり30分間かそれ以上，ほぼ毎日行うことを推奨している．

●エコチル調査のデータを基にした検討では，妊娠前の身体活動は早産や分娩方法に影響を及ぼさなかった．一方で妊娠中の身体活動量が低下すると，早産および帝王切開や器械分娩のリスクがわずかに上昇した．

●運動する習慣がない女性でも，妊娠判明した後から運動習慣を見直すことはよい機会である．妊娠中に適度に体を動かすと，早産および帝王切開や器械分娩のリスクが下がる可能性がある．7.5〜15Mets･時/週の身体活動量が推奨される．
