Outline
To investigate the mediating effect of healthy lifestyle between personality traits and obesity among primary school students in grades 4-6, so as to provide evidence for targeted obesity interventions.
A cross-sectional survey and physical examinations were conducted among 3 519 primary school students in grades 4-6 from 14 schools in Changzhou in 2024 by stratified cluster random sampling method. The personality traits were measured by the Big Five Inventory-10. The healthy lifestyle was assessed across four dimensions: healthy diet, moderate exercise, adequate sleep and reasonable screen time. A structural equation model was constructed to analyze the association between personality traits and obesity in primary school students and the mediating effect of the healthy lifestyle.
The detection rate of obesity among primary school students in grades 4-6 was 20.60%, significantly higher in boys (25.16%) than girls (15.49%) (χ2=50.127, P<0.001). The detection rate of obesity decreased significantly with the increase of education level of father and mother (all P<0.05). The total score of healthy lifestyle and the score of conscientiousness were negatively correlated with obesity (rs=-0.066, P<0.001; rs=-0.058, P<0.001). After controlling for gender and parental education, the model results showed that the indirect effect of conscientiousness on obesity through healthy lifestyle was -0.010 (95% CI: -0.018~-0.002), and the mediating effect accounted for 18.87% of the total effect.
Conscientiousness can directly or indirectly affect obesity among primary school students in grades 4-6 in Changzhou through healthy lifestyle. Personalized intervention programs for childhood obesity should be designed in combination with personality traits to promote healthy lifestyle.
