Background Body image is considered as central to many aspects of human functioning including emotions, thoughts, behaviors and relationships. Our study aimed to investigate the prevalence of body image distortion and dissatisfaction among adolescents and to assess their main determinants. Methods This was a cross-sectional school-based study conducted among school-adolescents in the south of Tunisia, between October 2017 and February 2018. Results Among 1210 school-adolescents, body image distortion and dissatisfaction prevalence were 44.8% and 42.4%, respectively. Multivariate analysis showed that being in the 16–18 years age group [adjusted odds ratio (AOR) = 1.28, p = 0.046], low family financial situation (AOR = 1.88, p = 0.014), as well as high frequency of eating pasta (AOR = 1.3, p = 0.04) and fast-food consumption (AOR = 1.7, p = 0.042) were independently associated with under-estimated body image. Skipping breakfast (AOR = 1.9, p = 0.017) and having one obese parent (AOR = 1.9, p = 0.01) were independently associated with higher frequency of over-estimated body image. Regarding body image dissatisfaction, independent factors associated with desire to lose weight were: female gender (AOR = 1.53, p = 0.007), high income family financial situation (AOR = 2.1, p = 0.008) and having one parent who is obese (AOR = 2.21, p < 0.001). However, frequent fast-food consumption (AOR = 1.9, p = 0.038) and eating between meals (AOR = 1.57, p = 0.01) were independently associated with a higher desire to gain weight. Conclusions Our study highlighted that the prevalence of body image distortion and dissatisfaction were substantially high among adolescents. Their determinants included socio-demographic factors and lifestyle behaviors. Increased awareness among parents, educators and public health planners may help adolescents improve accuracy of body image attitudes.

Background Tuberculosis (TB) is a public health problem worldwide. Characterizing its trends over time is a useful tool for decision-makers to assess the efficiency of TB control programs. We aimed to give an update on the current chronological trends of TB in Southern Tunisia from 1995 to 2016 and to estimate future trajectories of TB epidemic by 2030. Methods We retrospectively collected data of all notified TB new cases by the Center of Tuberculosis Control between 1995 and 2016 in South of Tunisia. Joinpoint Regression Analysis was performed to analyze chronological trends and annual percentage changes (APC) were estimated. Results In the past 22 years, a total of 2771 cases of TB were notified in Southern Tunisia. The annual incidence rate of TB was 13.91/100,000 population/year. There was a rise in all forms of TB incidence (APC = 1.63) and in extrapulmonary tuberculosis (EPTB) (APC = 2.04). The incidence of TB increased in children and adult females between 1995 and 2016 (APC = 4.48 and 2.37, respectively). The annual number of TB declined in urban districts between 2004 and 2016 (APC = -2.85). Lymph node TB cases increased (APC = 4.58), while annual number of urogenital TB decreased between 1995 and 2016 (APC = -3.38). Projected incidence rates would increase to 18.13 and 11.8/100,000 population in 2030 for global TB and EPTB, respectively. Conclusions Our study highlighted a rise in all forms of TB and among high-risk groups, notably children, females and lymph node TB patients in the last two decades and up to the next one.

Purpose Recently, there has been a renewed interest in medical students’ mental health. The purpose of this paper is to determine factors associated with psychological distress in medical students and to assess the correlation between major lifestyle behaviours and mental health. Design/methodology/approach The authors conducted a cross-sectional questionnaire survey among 530 medical students randomized from a faculty of medicine in 2017. The authors used the 12-item General Health Questionnaire (GHQ-12) and the Simple Lifestyle Indicator Questionnaire (SLIQ) to assess mental health and lifestyle, respectively. Findings The mean value of GHQ-12 and SLIQ were 4.1±2.8 and 6.2±1.4, respectively. Bivariate correlation analysis showed that SLIQ was significantly correlated to GHQ-12 (r=−0.26; p<0.001). The prevalence of psychological distress (GHQ-12=4) was 50.1%. The authors found that low/middle financial situation of the family (OR=1.5; CI 95%=[1.1–2.3]), internship level, (OR=1.8; CI 95%=[1.1–3.3]), medium/poor perceived academic performance (OR=2.2; CI 95%=[1.5–3.2]) and medium/poor perceived health status (OR=2.3; CI 95%=[1.5–3.6]) were significantly associated with psychological distress. Multivariate analysis performing logistic regression showed that average and unhealthy lifestyle were independently associated with psychological distress, with an adjusted OR of 3.7 (CI 95%=[1.7–7.7]) and 5.8 (CI 95%=[2.4–14.8]), respectively. Originality/value The study highlighted the magnitude and the risk factors of psychological distress in medical students. Unhealthy lifestyle was a potential predictive of mental disorders. These findings provide fundamental information for future researches.
