ABSTRACT
Using a questionnaire survey, this study examined Latinx mothers’ (n = 72) perception of Latinx grandparents’ involvement in children’s physical activity. Data were collected about a specific child (i.e., focal child) and a specific grandparent who spent the most time with the focal child (i.e., focal grandparent). Results showed that mothers perceived a substantive level of grandparental support for child’s physical activity and a small-to-moderate level of disagreement with grandparent in child’s physical activity. Mother-grandparent disagreement negatively affected grandparent’s support, which in turn positively affected child’s physical activity. Socio-demographic and household-related correlates of mother-grandparent disagreement and grandparent’s support were also examined.
