医学研究所(IOM)的指南是使用最广泛的妊娠期体重增加指南；然而，越来越多的证据表明亚洲人的身体成分不同于其他种族，这引发了人们对直接应用这些指南是否合适的担忧。我们的目的是研究日本女性的最佳妊娠体重增加与孕前体重指数(BMI)的差异程度，并将估计的最佳妊娠体重增加与当前日本和医学研究所(IOM)的建议进行比较。我们使用日本国家围产期网络数据库，对2005-2011年间104,070例未分娩妇女的单胎妊娠进行了回顾性研究。在孕前体重指数的五个亚组(17.0-18.4、18.5-19.9、20-22.9、23-24.9和25-27.4 kg/m2)中，我们使用多元回归方法估计妊娠增重率与妊娠结局(胎儿生长、早产和分娩并发症)之间的关系。与不良结果风险最低相关的体重增加率随着上述五种BMI类别的BMI(12.2公斤、10.9公斤、9.9公斤、7.7公斤和4.3公斤/40周)的增加而下降。目前日本的指南低于最优增量，BMI低于18.5公斤/平方米的女性不良后果风险最低，而国际移民组织目前的建议高于BMI超过23公斤/平方米的女性的最佳增量。孕期最佳体重增加在很大程度上取决于孕前BMI，根据世界卫生组织的建议，将BMI超过23公斤/平方米的人定义为超重，在将国际移民组织目前的建议应用于日本指南时可能会很有用。在日本，我们估计了优化妊娠结局的妊娠体重增加。孕前体重指数为17.0~18.4g/m2时，最适增重为12.2g/40周。孕前BMI为25.0~27.4 kg/m2时，最适增重为4.3 kg/40周。目前的国家指导方针对孕前体重指数为18.5千克/平方米的女性来说太低了。如果采用国际移民组织的建议，体重指数为23千克/平方米的人应被定义为超重。
The Institute of Medicine (IOM) guidelines are the most widely used guidelines on gestational weight gain; however, accumulation of evidence that body composition in Asians differs from other races has brought concern regarding whether their direct application is appropriate. We aimed to study to what extent optimal gestational weight gain among women in Japan differs by pre-pregnancy body mass index (BMI) and to compare estimated optimal gestational weight gain to current Japanese and Institute of Medicine (IOM) recommendations. We retrospectively studied 104,070 singleton pregnancies among nulliparous women in 2005–2011 using the Japanese national perinatal network database. In five pre-pregnancy BMI sub-groups (17.0–18.4, 18.5–19.9, 20–22.9, 23–24.9, and 25–27.4 kg/m2), we estimated the association of the rate of gestational weight gain with pregnancy outcomes (fetal growth, preterm delivery, and delivery complications) using multivariate regression. Weight gain rate associated with the lowest risk of adverse outcomes decreased with increasing BMI (12.2 kg, 10.9 kg, 9.9 kg, 7.7 kg, and 4.3 kg/40 weeks) for the five BMI categories as described above, respectively. Current Japanese guidelines were lower than optimal gains, with the lowest risk of adverse outcomes for women with BMI below 18.5 kg/m2, and current IOM recommendations were higher than optimal gains for women with BMI over 23 kg/m2. Optimal weight gain during pregnancy varies largely by pre-pregnancy BMI, and defining those with BMI over 23 kg/m2 as overweight, as proposed by the World Health Organization, may be useful when applying current IOM recommendations to Japanese guidelines. We estimated gestational weight gain that optimizes pregnancy outcomes in Japanese. Optimal gain was 12.2 kg/40 weeks for pre-pregnancy BMI 17.0–18.4 kg/m2. Optimal gain was 4.3 kg/40 weeks for pre-pregnancy BMI 25.0–27.4 kg/m2. Current national guidelines are too low for women with pre-pregnancy BMI < 18.5 kg/m2. BMI > 23 kg/m2 should be defined as overweight if applying IOM recommendations.
