Background and Aim: Obesity in adolescents can have serious consequences for their physical and mental health. Betty Newman's systems model can be used as an effective framework for designing care programs for obese adolescents. The aim of this study was to determine the effect of a care program based on Betty Newman's systemic model on the quality of life of obese adolescents studying at schools of Khorramabad city, Iran.
Materials and Methods: This research was a semi-experimental study with a pretest-posttest design with a randomized control group. 64 obese adolescents aged 12 to 18 years were selected from obese adolescents studying in the first and second secondary schools of Khorramabad city using a using convenience sampling and then randomly assigned. The intervention group received a care program based on the Betty Newman systemic model in 6 sessions. The data collection tools in the present study were a demographic form and health-related quality of life (HRQoL). The data were analyzed using SPSS version 22 software.
Results: At baseline, the mean quality-of-life score was significantly lower in the intervention group than in the control group (58.7 ± 9.8 vs. 67.8 ± 8.6, p <.001). Following the intervention, the mean quality-of-life score was 57.9 ± 10.3 in the intervention group and 69.9 ± 9.4 in the control group, and the difference between the two groups remained statistically significant (p <.001).
Conclusion: The findings of the present study showed that the intervention based on Betty Neuman's systems model did not lead to an improvement in quality-of-life scores among adolescents with obesity during the study period. Despite the lack of significant improvement observed in the present study, the findings provide useful evidence for the development and refinement of school-based programs aimed at promoting the well-being and quality of life of adolescents with obesity.
