Association Between Prepregnancy Body Mass Index and Severe Maternal Morbidity.

ABSTRACT:

Importance

Although high body mass index (BMI) is associated with adverse birth outcomes, the association with severe maternal morbidity is unclear.

Objective

To examine the association between prepregnancy BMI and severe maternal morbidity.

Design, setting, and participants

Retrospective population-based cohort study including all singleton hospital births in Washington State, 2004-2013. Demographic data and morbidity diagnoses were obtained from linked birth certificates and hospitalization files.

Exposures

Prepregnancy BMI (weight in kilograms divided by height in meters squared) categories included underweight (<18.5), normal BMI (18.5-24.9), overweight (25.0-29.9), obesity class 1 (30.0-34.9), obesity class 2 (35.0-39.9), and obesity class 3 (≥40).
