Background: People's lives were seriously affected by the emergence and the spread of the COVID-19 disease. Several vaccines were developed in record time to overcome this pandemic. However, putting an end to this public health problem requires substantial vaccination coverage rate. This latter depends on the acceptance of these vaccines especially by health professionals; the leaders of the current war against COVID-19. In fact, they have a central role in promoting vaccination against the SARS-CoV-2. In the developed countries, hesitancy rates towards these vaccines among health professionals vary from 4.3% to 72%. In the developing countries, few studies focused on this issue. Objective: To estimate the prevalence and the predictors of SARS-CoV-2 vaccine hesitancy among the Tunisian health professionals. Methods: A cross-sectional study was led online between the 7th and the 21th of January 2021 among Tunisian health professionals. At least 460 participants were required. Snowball sampling method served to recruit participants. Data were collected using a pre-established and pre-tested questionnaire recorded in a free Google form. The link of the questionnaire was disseminated online to be self-administered anonymously to the participants. The generated online Google Sheet was uploaded and exported to SPSS software for analysis. Results: Of the 546 responses, 493 were retained. The mean age of participants was 37.4 (± 9.5) years. Females represented 70.2% of participants. Social media represented the most frequently used source of information about COVID-19. The prevalence of SARS-CoV-2 vaccine hesitancy among participants was 51.9% (95% CI: 47.5–56.3)). Female sex, working far from the capital and having concerns about the vaccines components predicted more hesitancy among participants. In contrast, the use of the national COVID-19 information website predicted less hesitancy among them. Conclusions: The current Tunisian communication plan about COVID-19 vaccines must be reinforced. Social media represent a cost effective communication channel that can serve to reassure Tunisian health professionals regarding the safety of COVID-19 vaccines. Special interest should be paid to females, paramedical professionals and those working far from the capital.

Hypertension can originate in childhood and remain undetected unless special screening is performed. The burden of hypertension in adolescents in Tunisia is unknown. The aim of this study was to investigate the prevalence of blood pressure (BP) within the hypertension range and its association with other risk factors among Tunisian adolescents. A cross-sectional study that included 1385 secondary school students in Sousse, Tunisia, was performed during 2017–2018. A two-stage cluster sampling strategy was used to obtain a representative sample of the study population. BP within the hypertension range (HBP)was classified following the European guideline recommendations for measuring BP in children and adolescents. Anthropometric indices were measured using a standard protocol. A structured questionnaire collected information about sociodemographic characteristics, lifestyle, mental health status, and addictions. Adjusted logistic regression models were used to assess hypertension-related risk factors. Our study included 39.5% boys and 60.5% girls. The mean age of our population was 17 ± 1.5 years. The prevalence of HBP was 15.4% (13.1–18.0%), and it was significantly higher in boys (22.8%) than in girls (10.6%, p value < 0.001). In the multivariate logistic regression model, overweight [OR = 1.72(1.18–2.51)] and obesity [OR = 3.73(2.55–5.41)] were independent risk factors for HBPrange, (p value < 0.001), whereas female sex [OR = 0.41(0.29–0.56), p value < 0.001] and depression [OR = 0.67(0.51–0.88), p value = 0.008] were independent protective factors. Among Tunisian secondary school adolescents, the prevalence of HBP was high and associated with excess body weight. A comprehensive strategy for the prevention of hypertension and its risk factors among youth is urgently needed.

Introduction: Early adolescence is a critical period usually associated with experimentation with illicit substances. In Tunisia few studies explored these risk behaviors among young adolescents. Aims: To evaluate the prevalence and the predictors of the use of illicit substances among the young adolescents of Sousse. Methods: A cross-sectional study was conducted in the region of Sousse, Tunisia during the 2013/2014 school year among 4272 schoolchildren in 16 public middle schools. Data about psychosocial characteristics and risk behaviors among the schoolchildren, their parents, their siblings and their friends were collected anonymously using a self-administrated questionnaire. Results: Females represented 50.5% of participants. The mean age of schoolchildren was 13.3 (±1.2) years. Lifetime illicit substances use prevalence was 2.9% [confidence interval (CI) 95%: (2.4%–3.4%)] and lifetime use of tobacco prevalence was 12.9% [CI 95%: (11.9%–13.9%)]. The age of tobacco onset was significantly younger to the age of experimentation with illicit substances. Insomnia, sadness and illicit substances use among peers were associated with illicit substances use among participants. While the most influential risk factor on illicit substances use was current cigarette smoking with an adjusted odds ratio (OR) of 7.2 [CI 95%: (4.5–11.2)]. Conclusion: A national substances use prevention program should be implemented in the schools of Tunisia with an emphasis on tobacco use prevention.

Background and Aim: The COVID‐19 is a stigmatizing infectious disease even after healing. Until now, no COVID‐19 stigma scale validated in Tunisian Arabic language among the general population is available. Developing such tools is necessary to detect COVID‐19 stigma and reduce it effectively. Indeed, stigmatization of COVID‐19 patients could increase the spread of this disease and its related mental health issues. We aimed at testing the validity of a translated and modified version of the 12‐item HIV stigma scale among Tunisian COVID‐19 patients.Methods: A cross‐sectional study was conducted between November and December 2020 among a representative sample of COVID‐19 patients in the governorate of Sousse, Tunisia, after quarantine. The 12‐item HIV stigma scale was translated in Tunisian Arabic and then modified to be adapted to the Tunisian context. The preliminary modified version was administrated to the participants by pretrained medical doctors during phone calls. It consisted on 20 items covering the four stigma dimensions (personalized stigma, disclosure concerns, concerns with public attitudes, and negative self‐image). The psychometric evaluation of this version included internal consistency as well as principal component analysis (PCA).Results: The responses of 346 COVID‐19 patients were obtained. Their median age was 40 years (interquartile range: 30‐54.5). Females represented 60.4% of them. The PCA resulted in a three factor solution with 14 items. This 14‐item scale demonstrated good internal consistency with a global Cronbach's α of 0.91 and values of 0.94, 0.93, and 0.98 for social stigma, negative self‐image, and disclosure concerns, respectively.Conclusion: This study provides a reliable and valid instrument for stigma measuring among Tunisian COVID‐19 patients. The use of this scale would contribute in reducing the spread of this new infectious disease and its related mental health issues.
