Abstract summary 

The escalating prevalence of adolescent obesity represents a complex public health challenge, influenced by interactions of environmental, socio-economic, and behavioral factors. Recent studies reveal a surge in addictive substance use among adolescents, with non-substance addictions. Overweight adolescents are particularly susceptible to risky behaviors. Tunisia is not exempt from this issue, facing a rapidly increasing prevalence.Our work aimed to assess the prevalence of obesity among adolescents and to explore the connections between sociodemographic factors, mental health, and overweight in this demographic group.A cross-sectional study was led among sample of Tunisian high school adolescents from Sousse. We enrolled study participants through proportional stratified sampling.Our study included 1399students, predominantly female, with an average age of 17±1.5 years. The average BMI (Body Mass Index) was 22.7±4.1 kg/m². According to the International Obesity Task Force (IOTF), 20.4% were overweight, and 7% were obese, resulting in an overall weight excess prevalence of 27.4%. Girls exhibited a higher weight excess prevalence compared to boys. Multivariate analysis identified factors associated with overweight and obesity, including maternal self-employment(aOR=2.13,[1.35-3.35];p<0.001), regular physical activity (aOR=0.61,[0.47-0.8];p<0.001), internet usage ≥2 hours (aOR=0.70,[0.50-0.99];p=0.045), daily fruit-vegetable consumption (aOR=1.51,[1.15-1.97]; p=0.003), possible alexithymia (aOR=1.55,[1.07-2.22];p=0.018), probable anxiety (aOR=1.28,[0.87-1.89]; p=0.007), very probable anxiety (aOR=1.61,[1.14-2.2]; p=0.037), and problematic Facebook-use (aOR=0.67,[0.50-0.89]; p=0.006).Understanding factors tied to excess weight in our social and cultural context is crucial in shaping effective public health strategies. Interventions should adopt a multisectoral approach specifically targeting working mothers within the adolescent's socio-familial environment. It is fundamental also to address mental health concerns, with a particular focus on alexithymia and anxiety.
