Effectiveness study of interactive intervention on health literacy among fourth-grade students in Changning District， Shanghai

Objective To comprehensively analyze the impact of health literacy on fourth-grade students in a primary school in Changning District through the implementation of interactive interventions， providing a theoretical basis for the effective implementation of school health literacy initiatives.

Methods Using a cluster random sampling method， the effects of a 6-month interactive intervention were assessed among all fourth-grade students through two rounds of health literacy questionnaires conducted before and after the intervention.

Results Following the intervention， there was a significant increase in the overall rate of health literacy （86.80%）， knowledge of health beliefs （71.57%）， adherence to a healthy lifestyle （92.89%）， and basic health skills （76.14%） （P<0.001）. The rate of formation of student health behaviors after the intervention （90.10%） increased by 16.02% compared to the pre-intervention level （P<0.05）.

Conclusion Conducting interactive interventions can stimulate students’ enthusiasm for self-directed learning， facilitate the formation of health behaviors， and reduce the risk of disease occurrence. This approach plays a positive role in promoting students’ physical and mental health development and enhancing their level of health literacy.
