PMID 41685686

WHAT IT FOUND

Mothers experiencing violence had higher stress and depression, which weakened the mother-child bond.

This weakened bond was linked to externalizing behavior problems in their preschool children. Breastfeeding did not act as a protective factor in this chain.

Key findings

01Violence against women was associated with higher maternal stress and depression scores.

02Higher maternal depression was associated with a weaker mother-child bond, which in turn predicted externalizing problems in preschoolers.

03Breastfeeding showed no significant association with maternal stress, depression, or the quality of the mother-child bond.

What it does not show

The study is exploratory and cannot prove that violence caused these outcomes, only that they are associated. The sample was restricted to women without hypertension, diabetes, or smoking, limiting generalizability to higher-risk pregnancies. Attrition occurred over time, and 29 participants were excluded due to missing violence data. Violence was self-reported without prior clarification of definitions, which may have led to underreporting. Child behavioral outcomes were reported solely by caregivers, introducing potential bias. The study did not measure prenatal depression, so it is unclear if pre-existing mental health issues influenced the findings.

Declared interests

The authors declare no conflicts of interest. Funding was provided by Brazilian public research agencies (CNPq, FAPERGS) and the Hospital de Clínicas de Porto Alegre.

The easy way to misread this

Do not interpret these findings as proof that violence directly causes child behavioral problems. The study identifies an association where maternal stress and depression mediate the effect on the mother-child bond, which is then linked to child behavior. The direction of causality cannot be confirmed from this exploratory analysis.
