Exposure to secondhand smoke, exclusive breastfeeding and infant adiposity at age 5 months in the Healthy Start study.

ABSTRACT:

Background

Infant adiposity may be influenced by several environmental risk factors, but few studies have explored these interactions.

Objective

To examine the interaction between exposure to secondhand smoke and breastfeeding exclusivity on adiposity at age 5 months.

Methods

We studied 813 mother-offspring pairs from the longitudinal Healthy Start study. Fat mass and fat-free mass were measured by air displacement plethysmography. Linear regression analyses were used to estimate the association between household smokers (none, any) with fat mass, fat-free mass, percent fat mass, weight-for-age z-score, weight-for-length z-score and BMI-for-age z-score as separate outcomes. Interaction terms between household smokers and breastfeeding exclusivity (<5 months, ≥5 months
