This study...

It presents a conceptual framework for a comprehensive multilevel parenting and family support strategy for reducing the prevalence of parenting difficulties and other family risk factors associated with child maltreatment and the...

METHODS Data from the first two sweeps of the nationally representative prospective UK Millennium Cohort study were used. Drinking patterns during pregnancy and behav...
