To determine the effect of inadequate gestational weight gain (GWG) on neonatal birth weight in diabetic obese women.STUDY DESIGN:
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.RESULT:
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.CONCLUSION:
Inadequate GWG was associated lower mean birth weights, lower rates of cesarean delivery and lower rates of pregnancy-related hypertensive disorders.
