Maternal overweight and obesity in early pregnancy and risk of infant mortality: a population based cohort study in Sweden.

ABSTRACT:

Objective

To investigate associations between maternal overweight and obesity and infant mortality outcomes, including cause-specific mortality.

Design

Population based cohort study.

Setting and participants

1,857,822 live single births in Sweden 1992-2010.

Main outcome measures

Associations between maternal body mass index (BMI) in early pregnancy and risks of infant, neonatal, and postneonatal mortality, overall and stratified by gestational length and by causes of infant death. Odds ratios were adjusted for maternal age, parity, smoking, education, height, country of birth, and year of delivery.

Results

Infant mortality rates increased from 2.4/1000 among normal weight women (BMI 18.5-24.9) to 5.8/1000 among women with obesity grade 3 (BMI ≥ 40.0). Co
