摘要

Aim

This study aimed to evaluate the effect of combining exercise and dietary intervention in the treatment of childhood obesity, and to explore the impact of parental involvement and other factors on the intervention effect, to provide a theoretical basis for formulating more effective childhood obesity management strategies.

Subject and methods

This study included nine randomised controlled trials (RCTs) up to August 2025 by systematically searching PubMed, Embase, Web of Science, Cochrane Library, and EBSCO databases. RevMan 5.4 and Stata 18 were used for data analysis, and subgroup analysis, regression analysis, and interaction analysis were performed.

Results

The combined exercise and diet intervention significantly reduced BMI (mean difference MD –0.28, 95% CI –0.33 to –0.22, p < 0.00001, I2 = 51%) and body weight (MD –1.82 kg, 95% CI –2.30 to –1.34, p < 0.00001, I2 = 24%). Subgroup analysis showed that parental participation significantly enhanced the intervention effect (Qb(1) = 4.17, p = 0.04), while there was no significant difference in the effect of exercise intensity, diet type, and intervention duration on BMI improvement. Regression analysis and interaction analysis showed that the combination of “moderate-intensity exercise + parental involvement + dietary management” had the most significant intervention effect (R2 = 0.9976, adjusted R2 = 0.9805, F(7,1) = 58.53, p = 0.0183), but the results need to be interpreted with caution due to the small sample size.

Conclusion

This study verifies the effectiveness of the combination of exercise and dietary intervention in the management of childhood obesity, and emphasizes the promotion effect of parental involvement on the intervention effect. The results suggest that parental involvement and moderate-intensity exercise are key factors in effective intervention strategies, providing practical guidance for future childhood obesity management, and it is recommended to prioritize these factors in intervention strategies.
