A042: Experimental Study on Health Promotion Action Model to Promote Students' Health Development in Chongqing

Background: The State has consistently prioritized the advancement of adolescents' physical and mental well-being, starting at the highest level of design. In response, the Healthy China Action Plan incorporates health promotion initiatives for primary and secondary schools. Our goal in this study was to support the overall growth of Chongqing's primary and secondary school children by building a "health promotion action model" out of a core consisting of one yuan, two channels, three forces, six aspects, and nine resources for exhaustive intervention research. Methods: A three-year experimental study including 112,316 elementary and secondary school students from 23 health promotion base schools in Chongqing was carried out from September 2020 to September 2023. The experiment's impact was confirmed, and the Chongqing model's efficacy in promoting students' health in primary and secondary schools was investigated, using one-way analysis of variance and cross-paired t-tests. Results and Analysis: At the primary school level, there was a substantial improvement (P < 0.05) in the body shape of boys in grades 1-3, girls in grade 6, and boys and girls in grade 5. Except for senior girls, they likewise demonstrated a substantial improvement (P < 0.05) at the secondary level. Regarding physical fitness, despite variations in lung capacity at the beginning grade level, lung capacity showed a substantial improvement over the course of all three years (P < 0.05). In terms of physical fitness, Grade 1, 2, and 7 boys' 50-meter displacement speed performance showed a more significant rise (P < 0.05), whereas Grade 1, 2, and 3 girls' 50-meter run performance showed an overall substantial improvement (P < 0.05). The primary school stage revealed a significant difference in the muscular strength and endurance from sit-ups over a three-year period (P < 0.05) for students in the remaining grades, with the exception of boys in grade 3 and boys and girls in grade 6. The secondary school stage revealed a significant difference in the overall number of girls' sit-ups (P < 0.05). Students in the experimental schools demonstrated a significant improvement (P < 0.05) in cardiorespiratory endurance, moving from passing to good-to-upper or even exceptional overall. Conclusion and Suggestion: In elementary and secondary school pupils, the model clearly promoted physical form, physical function, displacement speed, muscular strength and endurance, and cardiorespiratory endurance. It's advised to incorporate each school's unique circumstances, do extensive research on the waist and abdomen's flexibility and core development, and continue to refine the model's features while maintaining a healthy level of physical fitness.
