Birth weight is a marker that is often referred to determine newborn health, potential growth trajectories and risk of future disease. Accordingly, interventions to promote appropriate and healthy birth weight have been extensively studied and implemented in pregnancy. In particular, physical activity in pregnancy is recommended to promote appropriate fetal development and newborn birth weight. This systematic review and meta-analyses aimed to summarize the effect of physical activity during pregnancy specifically from randomized controlled trials on the following outcomes: birth weight, macrosomia, low birth weight, being large for the gestational age, and being small for the gestational age (Registration No.: CRD42022370729). 63 studies (16,524 pregnant women) were included. There was a significant negative relationship between physical activity during pregnancy and macrosomia (z = 2.16; = 0.03; RR = 0.79, 95% CI = 0.63, 0.98, I = 29%, = 0.09). No other significant relationships were found. Promoting physical activity during pregnancy may be an opportune time to reduce the risk of future chronic disease, such as obesity, through the prevention of macrosomia and the promotion of appropriate birth weights.
出生体重是一个常被用来判定新生儿健康状况、潜在生长轨迹以及未来疾病风险的指标。因此，为促进适宜且健康的出生体重而采取的干预措施已在孕期得到广泛研究和实施。特别是，孕期体育活动被推荐用于促进胎儿的正常发育和新生儿出生体重。本系统评价和荟萃分析旨在总结孕期体育活动对以下结局的影响，具体数据来自随机对照试验：出生体重、巨大儿、低出生体重、大于胎龄儿以及小于胎龄儿（注册号：CRD42022370729）。纳入了63项研究（16524名孕妇）。孕期体育活动与巨大儿之间存在显著负相关（z = 2.16；P = 0.03；RR = 0.79，95%CI = 0.63，0.98，I² = 29%，P = 0.09）。未发现其他显著相关性。孕期促进体育活动可能是通过预防巨大儿和促进适宜出生体重来降低未来慢性病（如肥胖症）风险的有利时机。
