The mediation effect of breastfeeding duration on the relationship between maternal preconception BMI and childhood nutritional risk.

Background: Higher maternal preconception body mass index (BMI) is associated with lower breastfeeding duration, which may contribute to the development of poor child eating behaviours and dietary intake patterns (components of nutritional risk). A higher maternal preconception BMI has been found to be associated with higher child nutritional risk. This study aimed to determine whether breastfeeding duration mediated the association between maternal preconception BMI and child nutritional risk.

Maternal Preconception Body Mass Index and Early Childhood Nutritional Risk.

Background: Risk factors for problematic child eating behaviors and food preferences are thought to begin during the preconception period. It is unknown if maternal preconception body mass index (BMI) is associated with child nutritional risk factors (eg, poor dietary intake and eating behaviors).

Objectives: We aimed to determine whether maternal preconception BMI was associated with child nutritional risk.
