Pre-pregnancy body mass index and the risk of adverse outcome in type 1 diabetic pregnancies: a population-based cohort study.

ABSTRACT:

Objective

To assess the risk of perinatal complications in overweight and obese women with and without type 1 diabetes (T1DM).

Design

Prospective population-based cohort study.

Setting

This study was based on data from the Swedish Medical Birth Registry from 1998 to 2007.

Participants

3457 T1DM and 764 498 non-diabetic pregnancies were included. T1DM was identified based on ICD code O24.0. Mothers were categorised according to pre-pregnancy body mass index (BMI: weight in kilograms per height in square metres) as normal weight (BMI 18.5-24.9), overweight (BMI 25-29.9) or obese (BMI ≥30). Only women with singleton pregnancies and with data on BMI were included. PRIMARY/SECONDARY OUTCOMES: The primary outcome was large for gestational age (LGA: birth weight >90
