BJOG 2012; DOI: 10.1111/j.1471-0528.2011.03277.x Objective  To determine if disproportionate body composition is a risk factor for perinatal complications in large-for-gestational-age infants born to mothers with type 1 diabetes. Design  Population-based cohort study. Setting  Data from the Swedish Medical Birth Registry from 1998 to 2007. Population  National cohort of 3517 infants born to mothers with type 1 diabetes. Only singletons with gestational age 32-43 weeks were included. Methods  Large for gestational age (LGA) was defined as birthweight > 90th centile and appropriate for gestational age (AGA) as birthweight between 10th and 90th centiles. Disproportionate (D) infants were defined as having a ponderal index [PI: calculated as birthweight in grams/(length in cm)³ > 90th centile] and proportionate (P) as PI ≤ 90th centile. LGA infants were classified as P-LGA or D-LGA. Odds ratios were calculated for D-LGA and P-LGA infants, with AGA infants as the reference category. Odds ratios were adjusted for mode of delivery, fetal distress and stratified by gestational age. Main outcome measures  The primary outcome was a composite of neonatal morbidities, i.e. any of the following diagnoses: Apgar score < 7 at 5 minutes, birth trauma (Erb's palsy or clavicle fracture), respiratory disorder, hyperbilirubinaemia or hypoglycaemia requiring treatment. Results  Composite morbidity was significantly more frequent in LGA as opposed to AGA infants, but there was no difference in risk between P-LGA and D-LGA infants. Conclusions  High birthweight, irrespective of body proportionality, is a risk factor for neonatal complications in offspring of women with type 1 diabetes.
