Cross-sectional study of co-occurring addiction problems among high school students in Tunisia

Abstract

Background: Addictive behaviours are a major public health problem, especially among adolescents, who are susceptible to experiencing multiple co-occurring addictions. Aim: To assess the prevalence of addiction problems and co-occurrences of addictive behaviours (substance abuse, problematic video gaming and social media addiction) and disorders among high school students in Sousse, Tunisia. Methodology: A cross-sectional study was conducted in 2018 in public high schools, in the urban area of Sousse, Tunisia. A structured self-administered questionnaire was used to obtain relevant information from the students. Statistical analysis was performed using SPSS version 10 and confidence intervals of 95% were calculated. Chi-square test was used to compare qualitative variables and multinomial regression was conducted to determine independent factors related to the number of addictive behaviour co-occurrences. Results: Of the 1399 high school students, 60.5% were girls and mean age was 17 ± 2.28 years. Analysis of single addiction problems revealed 20.9% prevalence for all tobacco products, 10.1% for alcohol, 7.0% for all drugs, 36.1% for Facebook, and 35.3% for video games. Analysis of co-occurring addiction problems showed that 46.0% of the study population had 1 addiction problem, 12.2% had 2 addiction problems, 4.5% had 3, and 2.7% had the maximum number of 4 addiction problems. Multinomial regression showed an increase in co-occurrence of addiction problems among boys (aOR = 217.004; P < 0.001), participants who had repeated a school grade (aOR = 0.232; P < 0.001), those who had moderate or severe depression (aOR = 0.232; P < 0.001), and those who were anxious (aOR = 0.335; P = 0.003) and had alexithymia (aOR = 0.361; P = 0.005). Conclusion: The rate of co-occurrent addictions among adolescents in Sousse, Tunisia, is alarming. Problematic use of Facebook, gaming and tobacco use were the most frequent addictive behaviours. There is an urgent need for effective and multisectoral programmes to prevent addictions among children in Tunisia and other countries in the Middle East and North Africa Region.
