Correlates of Parental Physical Activity: A Quantitative Systematic Review

BACKGROUND: Despite the benefits of physical activity (PA), evidence suggests around 25% of adults fail to meet PA guidelines, parents, and mothers in particular, and engage in less PA on average than their childless peers. This review sought to determine the correlates of parental PA, stratifying evidence by self-report and device-based measures. METHODS: Quantitative studies (cross-sectional and longitudinal) investigating associations between correlates and parental PA (ie, parents with children aged 0-18 y) were identified across 4 databases (MEDLINE, EMBASE, PsycINFO and Scopus) up to October 2024. Correlates (assessed in 3 or more studies) and direction of associations were extracted, described, and synthesized narratively according to the socioecological model (individual, interpersonal, organizational, environmental, societal). RESULTS: Of 4632 studies identified, 269 full texts were assessed and 105 studies included in the review. A total of 117 correlates were identified across all studies (103 for self-report measures, 55 for device-based). 53 correlates were assessed in 3/+ independent associations (n = 51 self-report, n = 14 device, n = 12 both). Consistently, partner PA was positively associated with parent PA regardless of measure used. Child PA, pet ownership, and environmental aesthetics were positively associated with (mothers') PA, whereas car ownership was negatively associated with PA. Only one policy-level factor (COVID-19 restrictions) was assessed, being negatively associated with parental PA. CONCLUSIONS: Family-based correlates of PA were positively associated with parental PA, suggesting these may support wider family engagement in PA. Evidence from fathers and from low- and middle-income countries is needed to gain a better understanding of parental PA in these groups.
