Breastfeeding and behavioural problems: Propensity score matching with a national cohort of infants in Chile.

ABSTRACT:

Importance

Potential effects of breast feeding on children's behaviour remains an elusive debate given inherent methodological challenges. Propensity score matching affords benefits by ensuring greater equivalence on observable social and health determinants, helping to reduce bias between groups.

Objectives

We examined whether the duration of breast feeding had an impact on children's externalising and internalising behaviours.

Study design

A cohort study (Encuesta Longitudinal de la Primera Infancia cohort) that included 3037 Chilean families who were enrolled in 2010. Follow-up data was collected in 2012.

Setting

General community.

Participants

Population-based sample. Eligibility criteria: children born full-term with complete data on matching variab
