Summary

This school-based cluster randomized controlled trial aims to assess the feasibility of implementing the Adolescent Tobacco Initiation Prevention (IATIP) and evaluate the potential efficacy of IATIP in preventing tobacco initiation and promoting the health and well-being of school adolescents in Dhaka, Bangladesh. The intervention consists of three 40-minute sessions, delivered over three successive days, including knowledge and skill-based lectures, interactive activities, and materials targeting tobacco prevention and health promotion.

Detailed description

Background and Aims: Adolescent tobacco use is a significant public health challenge, particularly in low- and middle-income countries like Bangladesh. An Intervention for Adolescent Tobacco Initiation Prevention (IATIP) has been developed to address this issue. This study aims to assess the feasibility of implementing the IATIP and evaluate its potential efficacy in preventing tobacco initiation and promoting health and well-being. Design: Pilot feasibility school-based cluster randomized controlled trial. Setting: Secondary schools in Dhaka city, Bangladesh. Participants: Adolescents in school years 8 and 9 attending participating schools in Dhaka (K = 8 clusters; N\~1280 participants). Intervention: The intervention consists of three 40-minute sessions, delivered over three successive days, including knowledge and skill-based lectures, interactive activities, and materials targeting tobacco prevention and health promotion. This intervention was developed based on evidence gathered from a quantitative survey, qualitative focus groups, and a systematic review. Measurements: The primary outcome is the feasibility of the intervention, assessed with recruitment and attrition rates, fidelity of delivery and acceptability. Secondary outcomes include the change in intention to initiate tobacco use; tobacco knowledge, attitudes, and beliefs; skills development related to tobacco resistance; and the promotion of mental well-being. Data will be collected through structured questionnaires administered at baseline and 1-month follow-up assessments for both intervention and control groups. A post-intervention process evaluation will be conducted among the students who participated in the intervention and the teachers using a mixed-method approach, incorporating both questionnaires and semi-structured interviews, to gain insights into intervention implementation, facilitation, participant experiences, and identify potential areas for improvement. Comments: This pilot feasibility trial addresses a critical gap in tobacco prevention initiatives tailored for Bangladeshi school adolescents. By combining evidence-based strategies, IATIP aims to empower adolescents with the knowledge and skills needed to resist tobacco initiation, while also targeting specific components to improve health and well-being, recognising the interconnected challenges of tobacco use and health and well-being among adolescents. Successful implementation of this pilot trial has the potential to reduce the intention to initiate tobacco use, limit exposure to second-hand smoke, and contribute to the overall health and well-being of school adolescents. Given the scalability of school-based interventions, the trial's success may pave the way for future large-scale definitive trials, influencing national policies and strategies.

Interventions

Type	Name	Description
BEHAVIORAL	Intervention for Adolescent Tobacco Initiation Prevention (IATIP)	The IATIP is an evidence-based tobacco prevention program tailored for Bangladeshi adolescents, integrating Behavior Change Techniques, the Behavior Change Wheel, and the Theoretical Domains Framework. Utilizing the Arena Blended Connected (ABC) model ensures effective delivery. Six key learning types are integrated to optimize knowledge acquisition, concept exploration, collaboration, discussions, practical application, and skill development. The curriculum comprises three core components addressing adolescents' challenges: the information curriculum cultivates factual awareness, the social competence curriculum strengthens refusal skills and social competencies, and the social influence curriculum builds resilience against tobacco-promoting social influences.
