Availability of health-promoting interventions in high schools in Quebec, Canada, by school deprivation level.

Introduction: School-based health-promoting interventions (HPIs) foster adolescent health and well-being. Access to HPIs may differ by the socioeconomic advantage of students at each school (school deprivation). We assessed the importance of health issues and availability of HPIs and extracurricular activities by school deprivation in high schools in Quebec, Canada.

Methods: In 2016/17, 2017/18 and 2018/19, we interviewed school principals or a designee in 48 public high schools classified as disadvantaged (33%) or advantaged (67%). Schools rated whether 13 common health-related issues were important (i.e. warranted intervention) in their student population and reported whether HPIs to address these or other health issues and/or sports or special interest extracurricular activities had been available in the past year.

Results: 84% of disadvantaged schools offered one or more HPIs in the past year compared to 73% of advantaged schools. Higher proportions of disadvantaged schools perceived most of 13 health-related issues as important. HPIs for bullying/exclusion, sex education and physical activity (issues subject to government mandates) were available in most schools. Higher proportions of disadvantaged schools offered non-mandated HPIs (i.e. for healthy eating, mental health/well-being and substance use). Higher proportions of advantaged schools offered extracurricular activities in all areas other than non-competitive sports, which was offered by equal proportions of advantaged and disadvantaged schools.

Conclusion: Government mandates appear to facilitate universal availability of HPIs in schools, possibly boosting equity in school-based health promotion. Further investigation of possible differences in the content, implementation and/or effects of HPIs based on school deprivation is warranted.
