To determine the effect of inadequate gestational weight gain (GWG) on neonatal birth weight in diabetic obese women.
Retrospective cohort study of women with an initial body mass index (BMI) ⩾30 kg m(-2) and gestational or type 2 diabetes was conducted. GWG was stratified: inadequate (<11 lbs), adequate (11 to 20 lbs) or excessive (>20 lbs). The primary outcome was birth weight. Secondary outcomes included hypertensive disorders, gestational age at delivery, mode of delivery and Apgar scores.
A total of 211 obese diabetic women were identified. Of those, 37% had inadequate GWG, 25% had adequate GWG and 38% had excessive GWG. Women with inadequate GWG had lower mean birth weights (P=0.048), as well as lower rates of cesarean delivery (P=0.017) and lower rates of pregnancy-related hypertensive disorders (P=0.026) compared with those with adequate and excessive GWG.
Inadequate GWG was associated lower mean birth weights, lower rates of cesarean delivery and lower rates of pregnancy-related hypertensive disorders.
确定孕期体重增加不足（GWG）对糖尿病肥胖女性新生儿出生体重的影响。
对初始体重指数（BMI）⩾30 kg m(-2) 且患有妊娠期糖尿病或2型糖尿病的女性进行回顾性队列研究。GWG被分为：不足（<11磅）、充足（11至20磅）或过多（>20磅）。主要结局是出生体重。次要结局包括高血压疾病、分娩孕周、分娩方式和阿氏评分。
共纳入211名肥胖糖尿病女性。其中，37%的女性GWG不足，25%的女性GWG充足，38%的女性GWG过多。与GWG充足和过多的女性相比，GWG不足的女性平均出生体重较低（P=0.048），剖宫产率较低（P=0.017），妊娠相关高血压疾病发生率较低（P=0.026）。
GWG不足与较低的平均出生体重、较低的剖宫产率和较低的妊娠相关高血压疾病发生率相关。
