Abstract

Introduction: this study assessed the relationship between exposure to secondhand smoking (SHS) and its association with self-reported anxiety, depression and susceptibility to smoking among adolescents in Lagos, Nigeria.

Methods: depression among study subjects was determined using the Patient Health Questionnaire-9 (PHQ-9) while the Generalized Anxiety Disorder - 7 (GAD-7) was used to determine anxiety levels. Susceptibility to smoking cigarettes was also determined while the Statistical Package for the Social Science (SPSS) 26.0 software was used for data analysis. Significant associations were determined at P-values <0.05.

Results: of the 300 adolescents surveyed (mean age 12.9±1.43), 7.6 % were regularly exposed to SHS, of which 3.0% were daily exposed to SHS indoors. In multivariable analyses, indoor SHS exposure for ≥ 1 hour daily was associated with increased odds for susceptibility to smoking (AOR=3.793; 95%-CI: 0.98-14.60; p= 0.052) and increased odds for depression (AOR=1.303; 95%-CI: 0.84-2.01; p= 0.228) and slightly reduced odds for anxiety (AOR=0.952; 95%-CI: 0.62-1.47; p=0.822).

Conclusion: secondhand smoking exposure was associated with higher odds of susceptibility to smoking cigarettes and depression among adolescents exposed to SHS, especially among females living in cramped accommodations. Further validation of these findings should however be determined by cohort study designs.
