Depression in a sample of Tunisian adolescents: prevalence, associated factors and comorbidity with anxiety disorders

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.

The relationship between serum levels of S-100β and anxiety symptoms in patients with acute stroke

BACKGROUND

Post-stroke anxiety (PSA) is a common neuropsychiatric affective disorder occurring after a stroke. Animal experiments have indicated that serum S-100β levels are closely related to anxiety disorder. No clinical study has been done to explore the relationship between serum S-100β levels and anxiety symptoms in patients with acute stroke. The aim of our study was to investigate the association between serum S-100β levels and PSA.

METHODS

One hundred twenty-six acute stroke patients were recruited and followed up for 1 month. Blood samples were collected within 24 h after admission. The levels of serum S-100β were measured by enzyme-linked immunosorbent assays. Patients with significant clinical symptoms of anxiety and a Hamilton Anxiety Rating Scale score >7 at 1 month after stroke were diagnosed as PSA.

RESULTS

Serum S-100β levels in the non-PSA group were lower than the PSA group (838.97 (678.20-993.59) ng/L vs. 961.87 (796.09-1479.59) ng/L, Z = -2.661, P = 0.008). In multivariate analyses, we found that decreased risk of PSA was associated with low tertile serum S-100β levels (≤753.8 ng/L, OR 0.062, 95% CI 0.008-0.475, P = 0.007).

CONCLUSIONS

Low serum S-100β levels at admission may be associated with the decreased risk of PSA.
