OBJECTIVES: To describe the prevalence of school-based tobacco prevention programme exposure among adolescents in low-income and middle-income countries (LMICs) and its association with psychosocial predictors of smoking.
DESIGN: Analysis of pooled cross-sectional data.
SETTING: Global Youth Tobacco Survey (GYTS), conducted in 38 LMICs.
PARTICIPANTS: This was a pooled analysis of data involving a total of 132 755 adolescent respondents to GYTS in 38 LMICs across Africa, Europe and Central/South America between 2014 and 2017.
EXPOSURE AND OUTCOME MEASURES: The primary independent variable for this study was self-reported exposure to school-based tobacco prevention programmes in the past year. Five psychosocial determinants of smoking were explored as outcomes: perceived addictiveness of nicotine, perceived harm of secondhand smoke exposure, support for restricting cigarette smoking at public indoor locations, support for restricting cigarette smoking at public outdoor areas and self-reported prediction of enjoying cigarette smoking. Multivariable logistic regression models were used to examine the relationship between exposure to school-based tobacco prevention programmes and study outcomes, controlling for sociodemographic and smoking-related characteristics of respondents.
RESULTS: Overall, 59.1% of adolescents in LMICs self-reported exposure to school-based tobacco prevention programmes. The country-specific prevalence of adolescent exposure to school-based tobacco interventions ranged from 24.9% in the Comoros to 99.3% in Turkmenistan. Exposure to school-based tobacco interventions was significantly associated with greater secondhand smoke harm perceptions (adjusted OR (AOR): 1.69; 95% CI: 1.69 to 1.70), perceptions of addictiveness (AOR: 1.37; 95% CI: 1.36 to 1.37) and supporting tobacco use restrictions indoors (AOR: 1.70; 95% CI: 1.69 to 1.70) and outdoors (AOR: 1.59; 95% CI: 1.59 to 1.60). Exposure to school-based tobacco interventions was associated with lower odds of anticipating enjoying cigarette smoking (AOR: 0.76; 95% CI: 0.76 to 0.76).
CONCLUSION: Exposure to tobacco prevention programmes in schools is suboptimal in LMICs. Given the protective associations described in this study from school-based tobacco prevention programme exposure, it is imperative that national governments implement school-based programmes into ongoing tobacco control measures.
