Barriers and facilitators of physical activity among school attending adolescents in Lagos State, Nigeria: A qualitative study exploring views and experiences of decision-makers in secondary schools

Background and Aims: Schools represent a unique setting for promoting lifelong physical activity during critical development stages of life. Opportunities for in-school physical activity largely depend upon school-level policies, practices, and administrative support. A significant information gap exists on the factors influencing adolescents' participation in school-based physical activity programs in Nigeria. This study aimed to identify and explore the barriers and facilitators of physical activity in school-attending adolescents in Lagos State, Nigeria. Methods: A qualitative study, using semistructured interviews, was conducted to explore the views and experiences of 21 decision-makers who were responsible for planning the physical and health education curriculum in secondary schools in Lagos State, Nigeria. Data were analyzed using the thematic analysis framework. Results: Eight themes were identified and explored. The barriers were (i) students' characteristics, (ii) parental objections, (iii) no prioritization of physical activity, (iv) insufficient resources, and (v) challenges with schools' initiatives. The facilitators were (vi) students' interests, (vii) students' awareness of benefits, and (viii) schools' initiatives. Conclusion: Our study findings can help in designing interventions to increase physical activity among school-attending adolescents in Lagos, Nigeria.
