Pregnancy weight gain by gestational age and stillbirth: a population-based cohort study.

ABSTRACT:

Objective

To study the association between total and early pregnancy (<22 completed weeks) weight gain and risk of stillbirth, stratified by early-pregnancy body mass index (BMI).

Design

Population-based cohort study.

Setting

Stockholm-Gotland Region, Sweden.

Population

Pregnant women with singleton births (n = 160 560).

Methods

Pregnancy weight gain was standardised into gestational age-specific z-scores. For analyses of total pregnancy weight gain, a matched design with an incidence density sampling approach was used. Findings were also contrasted with current Institute of Medicine (IOM) weight gain recommendations.

Main outcome measures

Stillbirth defined as fetal death at ≥22 completed weeks of gestation.

Results

For all BMI categories,
