Leading causes of death in Tunisia, 2020

Abstract Background Mortality data represent a primary source of information for monitoring a population health status over years. In Tunisia, the national Information System on Causes of Death (ISCD) lacks completeness (average coverage rate of 40%); however, in order to examine covid-19’s effect on mortality data, the ISCD was reinforced. We aimed to give an overview of leading causes of death in Tunisia for 2020. Methods Data were obtained from Medical Certificates of Cause Of Death (MCCOD) sent by municipalities to the National Institute of Health in accordance with the legislative framework. Causes of Death (CoD) coding process was performed based on the International Classification of Diseases, Tenth Revision (ICD-10). The underlying cause of death was identified based on IRIS software, and mortality statistics were presented based on the world health organization cause-of-death lists for tabulating mortality statistics. Data analysis was performed using SPSS software. Results A total of 46.420 MCCOD among 75.365 deaths officially declared by the National Institute of Statistics, were analyzed (coverage rate of 61.2%). The 10 leading causes of death for both sexes, in rank order were: diabetes mellitus, cerebrovascular diseases, covid-19, ischemic heart diseases, external causes of death, digestive and pulmonary malignant neoplasms, conditions of neonatal period, hypertensive diseases, and influenza and pneumonia. Leading causes of infant deaths were: certain conditions originating in perinatal period, congenital malformations, deformations and chromosomal abnormalities, diseases of respiratory system, certain infectious and parasitic diseases, and diseases of nervous system. Conclusions The COVID-19 pandemic was an opportunity to improve the Tunisian ISCD’s coverage rate. However, efforts should be maintained to optimize system completeness, and decision makers should be more sensitized regarding the urgent need for system digitalization. Key messages • Mortality statistics have shown that covid-19 ranks third among leading causes of death in Tunisia for 2020; and non communicable disease accounted for 6 out of 10 leading causes of deaths. • The ISCD coverage rate was improved in 2020 reaching 61.2%; however the system digitalization is an essential and sustainable solution to optimize completeness.


Background:
Nonmedical use of prescription drugs such as sedatives and anxiolytics is a fast growing public health threat in several countries. In Tunisia, although several studies have investigated the prevalence of nonmedical use of anxiolytics among school-age students, there is a gap in knowledge regarding trends in anxiolytics misuse. We aimed to determine the prevalence of nonmedical use of anxiolytics and examine trends between 2013 and 2021.

Methods:
Pooled data from three Mediterranean school surveys on alcohol and other drugs (MedSPAD I-2013, MedSPAD II-2017, MedSPAD III-2021 were used. Based on three-stage stratification sampling method, teenagers in first and second grades of secondary education, were enrolled. Were not included students enrolled in vocational training centers and out-of-school adolescents. Data collection was performed using a self-administered standardized questionnaire. We studied weighted lifetime nonmedical use of prescription anxiolytics and performed global and by gender trend analysis. Epi data software was used for data entry and all statistical analysis, were performed with STATA software.

Results:
A total of 14.723 students were enrolled with sex ratio (Male/ Female) equal to 0.61 and mean age of 16.2AE0.8 years. The prevalence of nonmedical anxiolytics' use increased from 2.1% to 3% then to 8.4% for 2013, 2017 and 2021, respectively. Global and by gender trends analysis concluded to significant increase from 2017 to 2021 (p < 10-3). However, a nonsignificant increase was revealed from 2013 to 2017.

Conclusions:
Our study is the first to confirm a significant increasing trend in non-medical use of anxiolytics among Tunisian adolescents. These findings emphasize the urgent need for early detection of psychological vulnerability among adolescents in order to prevent their engagement in such risky behaviors. Key messages: Decision makers should be sensitized regarding the alarming increasing trend in non-medical use of anxiolytics, among Tunisian adolescents.
The state control of these substances accessibility and early detection of psychological vulnerability, are highly required.
