Worldwide, children do not meet the recommended guidelines for physical activity (PA) and a unified approach is required to increase children¿s engagement in PA. Parents, are increasingly regarded as playing a key role in children¿s PA behaviours. Physical activity parenting (PAP) is growing as a research field and refers to parental behaviours intended to influence children¿s investment in PA. Using the perspectives of both parent and child, this research aims to identify PAP practices (positive and negative) engaged by Irish parents and to examine how PAP is embedded within a socioecological context. A purposive sample of 116 families in Ireland were included in the study. Families were stratified by social class, location, and family structure. Parents and children were interviewed and a secondary analysis of the interview data was completed. A theoretical model and conceptual framework relating to PAP guided data analysis to identify and understand parenting practices that influence children¿s PA behaviour. Data was deductively analysed and key findings indicated that PAP practices of encouragement, involvement, and facilitation were positively associated with children¿s engagement in structured sport activities. Co-participation was positively associated with children¿s participation in unstructured PA. Mothers and fathers differed in their PA roles, with fathers engaged to a greater extent in involvement parental practices. Children from middle and higher socio-economic class families participated in a greater repertoire of structured PA and benefited from a greater diversity of PAP practices. Family context (social class, structure, size), community resources and organisational factors mediated the presence of PAP practices. Parents¿ PA attributes and parents perceptions of PA attributes were less important influencers. Successful and effective engagement of parents in PA interventions is dependent on consideration of the various social contexts that are embedded in families.
