背景：有证据表明孕前体重指数和孕期体重增加对妊娠和出生体重有影响，但不同孕前体重指数类别的孕妇孕期体重增加对不良出生体重发生率的影响是否存在差异尚不清楚。方法：选择1617名与母亲匹配的儿童作为研究对象。结果：孕前体重不足和超重/肥胖的发生率分别为16.3%和12.3%。近15.2%的孕妇孕期体重增长低于美国医学学会指南，52.1%的孕妇孕期体重增长高于美国医学研究院指南。母亲超重和肥胖与巨大儿和胎龄过大的风险增加有关。妊娠体重增加低于美国医学学会指南的妇女比妊娠体重增加低于美国医学研究所指南的妇女更有可能出生体重低和小于胎龄。此外，在符合美国医学学会指南的女性中，巨大儿和巨大儿的风险增加。而对于孕前体重正常的女性，高于美国医学学会指南的孕期体重增加与巨大儿和巨大儿的发生率较高，而与类似孕前体重类别但符合美国医学学会指南的孕期体重增加的女性相比。结论：孕前体重指数和孕期体重增加异常的女性有不良出生体重结局的风险。此外，孕期体重增加对不同孕前体重指数类别的妇女的不良出生体重结局的发生率有不同的影响。(C)2017澳大利亚助产士学院。爱思唯尔有限公司出版。保留所有权利。
Background: Evidence suggests that pre-pregnancy body mass index and gestational weight gain have impact on pregnancy and birth weight, yet whether maternal gestational weight gain has a differential effect on the rates of adverse birth weight among women with different pre-pregnancy body mass index categories are unknown.Methods: We selected 1617 children matched with their mothers as study subjects. The subjects were divided into three categories: weight gain below the American Institute of Medicine guidelines, weight gain within the American Institute of Medicine guidelines and weight gain above the American Institute of Medicine guidelines.Results: The prevalence of pre-pregnancy underweight and overweight/obese women was 16.3% and 12.3%. And nearly 15.2% of the women had gestational weight gain below American Institute of Medicine guideline, 52.1% of the women had gestational weight gain above American Institute of Medicine guideline. Maternal overweight and obese was associated with increased risk for macrosomia and large-for-gestational age. Women had gestational weight gain below American Institute of Medicine guideline were more likely to have low birth weight and small-for-gestational age than women who had gestational weight gain within American Institute of Medicine guideline. Furthermore, the risks for macrosomia and large-for-gestational age were increased in women with above American Institute of Medicine guideline. And for women with a normal weight before pregnancy, gestational weight gain above the American Institute of Medicine guidelines were associated with higher rates of macrosomia and large-for-gestational age, compared with the women of similar pre-pregnancy weight category but with gestational weight gain within the American Institute of Medicine guidelines.Conclusions: Women with abnormal pre-pregnancy body mass index and gestational weight gain are at risk for adverse birth weight outcomes. Moreover, gestational weight gain has a differential effect on the rates of adverse birth weight outcomes between women of different pre-pregnancy body mass index categories.
