Association of tobacco experimentation with anxiety and depression: findings from a representative sample of Tunisian adolescents.

Objectives: Emerging evidence points to tobacco experimentation being associated with a vast array of mental disorders, particularly anxiety and depression. We aimed to assess the prevalence of tobacco experimentation, its predictive factors and its potential links with anxiety and depressive disorders among in school adolescents in a Tunisian delegation.

Methods: We carried out a cross sectional study among adolescents schooling in middle and high schools in the delegation of Nfidha, Sousse, Tunisia, during the period from January to March of the 2019-2020 school year using an anonymous questionnaire self-administered to a representative sample of 1,353 randomly selected pupils. Data were collected using the Arabic versions of the Beck Depression Inventory short form (13 items) and the Screen for Child Anxiety Related Disorders (SCARED-C) and a socio-demographic questionnaire with reference to the literature.

Results: Tobacco was experimented by (17.5 %; CI 95 %: 14.8-18.8 %) of pupils. Almost three out of four pupils (73.2 %; CI 95 %: 70.8-75.6 %) reported experiencing depressive symptoms and (65 %; CI 95 %: 62.5-67.5 %) anxiety symptoms. Pupils who exhibited depressive disorder indicators were significantly more prone to experiment with tobacco (20.2 vs. 9.9 %, p<0.001; crude OR=2.301 CI 95 %: 1.74-3.58). Similarly, the prevalence of tobacco experimentation was found to be higher among pupils who reported having experienced anxiety disorders (21.0 vs. 14.5 %, p<0.001; crude OR=1.56 CI 95 %: 1.06-2.27). Being a male pupil (AOR=5.48 95 % CI: 3.62-8.31), being be enrolled in a high school (AOR=2.86, 95 % CI: 1.92-4.26), tobacco use by father and siblings (respectively AOR=1.76, 95 % CI: 1.19-2.60; AOR=2.47, 95 % CI: 1.52-4.02) and experiencing depressive disorders (AOR=2.69, 95 % CI: 1.60-4.53) were the determinants of tobacco experimentation in the multivariate analysis.

Conclusions: Tobacco experimentation in adolescence has been shown to be significantly associated with anxiety and depression. National smoking prevention strategies should be reinforced with a focus on mental health disorders.
