N2 - OBJECTIVE-Since January 2008, obese women with type 2 diabetes were advised to gain 0- 5 kg during pregnancy. The aim with this study was to evaluate fetal growth and perinatal morbidity in relation to gestational weight gain in these women. RESEARCH DESIGN ANDMETHODS-A retrospective cohort comprised the records of 58 singleton pregnancies in obese women (BMI ≥30 kg/m2) with type 2 diabetes giving birth between 2008 and 2011. Birth weight was evaluated by SD z score to adjust for gestational age and sex. RESULTS-Seventeen women (29%) gained ≤5 kg, and the remaining 41 gained >5 kg. The median (range) gestational weight gains were 3.7 kg (24.7 to 5 kg) and 12.1 kg (5.5-25.5 kg), respectively. Prepregnancy BMI was 33.5 kg/m2 (30-53 kg/m 2) vs. 36.8 kg/m2 (30-48 kg/m2), P = 0.037, and median HbA1c was 6.7% at first visit in both groups and decreased to 5.7 and 6.0%, P = 0.620, in late pregnancy, respectively. Gestational weight gain ≤5 kg was associated with lower birth weight z score (P = 0.008), lower rates of large-for-gestational-age (LGA) infants (12 vs. 39%, P = 0.041), delivery closer to term (268 vs. 262 days, P = 0.039), and less perinatal morbidity (35 vs. 71%, P = 0.024) compared with pregnancies with maternal weight gain >5 kg. CONCLUSIONS-In this pilot study in obese women with type 2 diabetes, maternal gestationalweight gain#5 kgwas associatedwith amore proportionate birthweight and less perinatal morbidity.
