Australian children’s physical activity and screen time while in grandparental care

The objective of this study was to explore Australian children's engagement in physical activity and screen time while being cared for by their grandparents. Grandparents (N = 1,190) providing ≥3 hours of weekly care to a grandchild aged 3–14 years completed an online survey assessing their grandchildren's movement behaviours while in their care. Descriptive statistics were computed for frequency of engagement in unstructured and structured physical activities, minutes spent playing outdoors, and minutes spent engaged in screen time. Regression analyses were conducted to assess socio-demographic predictors of movement behaviours. Playing in the yard was the most common form of physical activity in which grandchildren reportedly participated (77% 'usually' or 'always'), followed by playing with toys/equipment (62%). Few (14–36%) frequently engaged in active transport. Children spent an average of 181 minutes per week engaged in screen-based activities. There is an opportunity to improve children's movement behaviours while in grandparental care. Communicating to grandparents their importance in supporting an active lifestyle is warranted. Findings highlight the importance of creating environments that facilitate play-based, outdoor activities. Ensuring children have access to play equipment while in the care of grandparents and improving access to and quality of neighbourhood parks may assist with activity promotion.
