The mediating role of social support in promoting physical activity among children in South Africa.
Howard Gomwe, Lesego Phiri, Chioneso Show Marange
PMID 37928649WHAT IT FOUND
Children who enjoy physical activity participate more, but this link depends heavily on encouragement from family and teachers.
Family support had the strongest effect, followed by teacher support. Peer encouragement alone did not significantly drive participation when family and teacher support were present.
Key findings
01Family encouragement was the strongest mediator between physical activity enjoyment and actual participation levels.
02Teacher encouragement also significantly mediated the relationship between enjoyment and participation, ranking second to family support.
03Peer encouragement did not have a significant direct effect on participation when controlling for family and teacher support.

What it does not show
The study relied on self-reported data from children, which may introduce recall bias or inaccuracies. The cross-sectional design means causality cannot be established; we do not know if support leads to participation or if active children seek more support. The sample was restricted to primary school children aged 9–14 in South Africa, so findings may not generalize to older adolescents or other cultural contexts. Selection bias was a concern, though the authors state random sampling minimized this.
The easy way to misread this
Do not assume peer support is ineffective. While it did not drive participation in this specific statistical model when family and teacher support were present, it still correlated with enjoyment. The lack of significance here may reflect the dominance of adult support in this age group rather than the irrelevance of friends.
