Breastfeeding initiation: impact of obesity in a large Canadian perinatal cohort study.

ABSTRACT:

Objective

To evaluate incidence of breastfeeding initiation according to maternal pre-pregnancy body mass index (BMI) in "Grossesse en Santé", a large prospective birth cohort in Quebec City.

Methods

Breastfeeding initiation in the post-partum period, pre-pregnancy BMI, sociodemographic determinants and obstetrical and neonatal factors were collected from years 2005 to 2010 in 6592 women with single pregnancies. Prenatal non-intention to breastfeed was documented in a subgroup of the cohort (years 2009-2010). Log-binomial regression analyses were performed to assess relative risk (RR) of non-initiation of breastfeeding between maternal BMI categories in models including pre- and post-natal determinants, after exclusion of variables with a mediating effect.
