目的：基于对不良母婴结局的显著风险估计，为每种孕妇体重指数(BMI)类别建立最佳孕期体重增加。方法：研究人群包括1994年1月1日至2004年12月31日在瑞典分娩的298,648例单胎妊娠。将每个体重增加类别中的个体数量与同一BMI组中所有其他体重增加类别中的个体数量进行比较，以了解不良的母婴结局。结果：孕前体重指数BMI<20者，孕期体重增加9~22磅(4~10公斤)，BMI 20~24.9岁，孕期体重增加5~22磅(2~10公斤)，BMI 25~29.9岁，孕期体重增加<20磅(<9公斤)，孕期体重增加5~22磅(2~10公斤)，孕期体重增加(P<0.05)。结论：瑞典医学登记处的这项基于人群的大型队列研究确定了BMI类别的孕期体重增加限度，结果表明，产科和新生儿不良结局的风险降低与妊娠体重增加限度低于先前推荐的水平有关，特别是在肥胖女性中。
OBJECTIVE: To establish optimal gestational weight gain for each maternal body mass index (BMI) category based on significant risk estimates of adverse maternal and fetal outcome.METHODS: The study population consisted of 298,648 singleton pregnancies delivered in Sweden between January 1, 1994, and December 31, 2004. The number of individuals in each weight gain class was compared with the number of individuals in all other weight gain classes in the same BMI group with regard to adverse maternal and fetal outcome. Odds ratios were calculated after suitable adjustments.RESULTS: The optimal gestational weight gain in women by prepregnancy BMI was 9-22 lb (4-10 kg) for BMI less than 20; 5-22 lb (2-10 kg) for BMI 20-24.9; less than 20 lb (less than 9 kg) for BMI 25-29.9; and less than 13 lb (less than 6 kg) for BMI of 30 or more.CONCLUSION: The gestational weight gain limits for BMI categories determined in this large population-based cohort study from Swedish Medical Registers showed that a decreased risk of adverse obstetric and neonatal outcomes was associated with lower gestational weight gain limits than was earlier recommended, especially among obese women.
