To study prepregnancy maternal body mass index (BMI) and overall maternal weight gain in triplet gestations in relation to maternal and newborn outcomes.
This was a retrospective study of birth certificate data of all live-born triplet gestations occurring between 1999 and 2003 in an eight-county region in New York. An analysis of computerized birth certificate data for variables related to pregnancy and newborn outcomes was conducted, looking at neonatal birth weight, neonatal gestational age, and the occurrence of the maternal pregnancy complications of gestational diabetes, gestational hypertension, and preeclampsia.
In 56 triplet gestations studied, the prepregnancy BMI was not associated with mean newborn birth weights and gestational age at delivery. The total maternal weight gain was associated with increasing mean birth weight and higher gestational age at delivery. Pregnancy complications in triplet pregnancies of gestational diabetes and gestational hypertension were associated with prepregnancy BMI, but not maternal weight gain.
For triplet gestations, a normal prepregnancy BMI and a total gestational weight gain of at least 15.9 - 20.5 kg (35 - 45 lb) are associated with fewer pregnancy complications.
研究三胎妊娠中孕前母体体重指数（BMI）及母体总体重增加与母体和新生儿结局的关系。
这是一项对1999年至2003年纽约一个八县地区所有存活的三胎妊娠出生证明数据的回顾性研究。对与妊娠和新生儿结局相关变量的计算机化出生证明数据进行分析，观察新生儿出生体重、新生儿胎龄以及母体妊娠并发症（妊娠期糖尿病、妊娠期高血压和先兆子痫）的发生情况。
在研究的56例三胎妊娠中，孕前BMI与平均新生儿出生体重及分娩时的胎龄无关。母体总体重增加与平均出生体重增加及分娩时胎龄较大有关。三胎妊娠中妊娠期糖尿病和妊娠期高血压的妊娠并发症与孕前BMI有关，但与母体体重增加无关。
对于三胎妊娠，孕前BMI正常且妊娠期总体重增加至少为15.9 - 20.5千克（35 - 45磅）与较少的妊娠并发症相关。
