Optimal maternal body composition during pregnancy is a public health priority due to its implications on maternal health and infant development. We therefore aimed to conduct a systematic review of randomised, controlled trials, and case-control and cohort studies using lifestyle interventions to improve body composition in developing countries. Of the 1 708 articles that were searched, seven studies, representing three countries (Brazil, Iran and Argentina), were included in the review. Two articles suggested that intervention with physical activity during pregnancy may significantly reduce maternal weight gain, and five studies were scored as being of poor quality. This systematic review highlights the lack of research within developing countries on lifestyle interventions for the management of excessive weight gain during pregnancy. Similar reviews from developed countries demonstrate the efficacy of such interventions, which should be confirmed using well-designed studies with appropriate intervention methods in resource-limited environments.
孕期最佳的母体身体组成是一项公共卫生重点事项，因为它会对母体健康和婴儿发育产生影响。因此，我们旨在对使用生活方式干预措施来改善发展中国家母体身体组成的随机对照试验、病例对照研究和队列研究进行系统综述。在检索到的1708篇文章中，代表三个国家（巴西、伊朗和阿根廷）的七项研究被纳入综述。两篇文章表明，孕期进行体育活动干预可能会显著减少母体体重增加，五项研究的质量被评为较差。这项系统综述凸显了发展中国家在孕期体重过度增加管理方面缺乏关于生活方式干预措施的研究。来自发达国家的类似综述证明了此类干预措施的有效性，应在资源有限的环境中通过设计良好且采用适当干预方法的研究来加以证实。
