Project PaThWay: protocol for a school-based health promotion intervention for prevention of non-communicable diseases (NCDs) behavioral risk factors

Abstract

Background: Prevention of non-communicable diseases (NCDs) and their behavioral risk factors (tobacco use, unhealthy diet, physical inactivity, harmful use of alcohol) among children and adolescents have garnered paramount importance under the Sustainable Development Goals. Methods: Project PaThWay is a school-based, two years, multi-component intervention to prevent key behavioral NCD risk factors among school-going children (classes 6-8th; 10-14 years) from private and public schools across two Indian cities (Pune and Bengaluru). We assessed the baseline knowledge, attitude, and behavior related to NCD risk factors (unhealthy diet, physical inactivity, and tobacco use) of the participating students through a survey. The intervention was developed and designed for implementation by the trained teachers and similar-age peers, as facilitators. The teachers and peer leaders were trained through organising school-level orientation workshops for implementation of intervention activities, after baseline assessment. Year 1 of the intervention focuses on the knowledge and learnings and year 2 on enhancing the life-skills (leadership, communication, refusal, health advocacy, etc.). Regular monitoring visits by the project team to ensure intervention activities are being carried out as planned and providing continuous support. The end line evaluation will be done after the completion of two years’ intervention to evaluate the effectiveness of the Project PaThWay intervention. Outcome measures will include improved knowledge, positive attitude, improve behaviors related to diet, physical activity, and tobacco use, and enhanced skills in handling NCD risk factors. A process evaluation will explore several aspects of Project PaTHWay intervention (fidelity, dosage, reach, adaptations), social validity (acceptability, feasibility, utility). Conclusion: Project PaTHWay, having a multiple-component intervention, may offer the best chance for success, as it addresses multiple risk factors using multi-pronged strategies. The agents of intervention implementation are trained teachers and similar-age student peer leaders (as facilitators), one of the successful and effective approaches in school-based interventions globally and in India.
