Peer support and perceptions of physical activity are significantly and positively associated with physical activity among secondary school students, with this association exhibiting different characteristics across gender groups but no significant differences across year groups.
Key Findings
Results
Nearly half of high school students reported low levels of physical activity.
46.0% of high school students reported low levels of physical activity
Sample consisted of 841 high school students surveyed using convenience (non-probability) sampling
Physical activity was measured using the Adolescent Physical Activity Questionnaire
Results
Boys received significantly more peer support for physical activity than girls.
Mean peer support score for boys was 14.46 ± 4.18
Mean peer support score for girls was 12.55 ± 3.89
Overall, high school students received relatively little support from both peers and parents
Results
No significant differences in peer support or parental support were found across grade levels.
p > 0.05 for both peer support and parental support differences across grade levels
This finding held across different year groups within the secondary school sample
Results
Parental support was not significantly associated with physical activity levels among secondary school students.
No significant association was found between parental support and physical activity (p > 0.05)
This finding applied across the full student sample
Models were constructed using stepwise and hierarchical regression via SPSS Statistics 26.0
Results
Peer support was significantly and positively associated with physical activity levels in both boys and girls, but the nature of the association differed by gender.
Among boys, peer support showed a significant positive association with both perceptions of physical activity and levels of physical activity (p < 0.01)
Among girls, only the positive association between peer support and physical activity levels was significant (p < 0.01)
Among girls, peer support was not significantly associated with perceptions of physical activity
Physical activity perception was measured using the Physical Activity Perception Questionnaire and social support via the Adolescent Physical Activity Social Support Scale
Results
Perceptions of physical activity were significantly and positively associated with physical activity levels among secondary school students.
A significant positive association was found between perceptions of physical activity and physical activity levels overall
This association was specifically confirmed as significant for boys (p < 0.01)
Statistical analysis used stepwise and hierarchical regression models
What This Means
This research surveyed 841 high school students in China to understand how social support from peers and parents, as well as students' own attitudes toward physical activity, relate to how physically active they are. The study found that nearly half of students (46%) had low physical activity levels, and that overall students received relatively little encouragement for physical activity from either peers or parents. Boys tended to receive more peer encouragement for physical activity than girls.
The study found that support from friends and peers was an important factor linked to higher physical activity levels for both boys and girls, but the relationship worked somewhat differently for each group. For boys, having more peer support was linked to both more positive views about physical activity and higher activity levels. For girls, peer support was linked to higher activity levels but not necessarily to more positive views about physical activity. Interestingly, support from parents did not show a significant connection to activity levels, and there were no meaningful differences in social support patterns across different school year groups.
This research suggests that public health nurses and school health professionals looking to increase physical activity among teenagers should consider focusing on peer-based interventions — such as encouraging group activities or social support networks among students — rather than relying primarily on parental involvement. The gender differences found also suggest that programs may need to be tailored differently for boys and girls to be most effective.
