This study aimed to assess the correlation between major lifestyle behaviors and mental health in medical students. Methods: A cross-sectional questionnaire survey was conducted among 521 medical students randomized from different levels, at Southern Tunisia Medical School, 2017. The 12-item General Health Questionnaire (GHQ-12) and the Simple Lifestyle Indicator Questionnaire (SLIQ) were used to assess mental health and lifestyle, respectively. Results: The mean values of GHQ-12 and SLIQ were 4.12.8 and 6.21.4, respectively. According to SLIQ components, we noted an unhealthy lifestyle in 36.9%, 50.1% and 20.2% for diet, physical activities and stress level, respectively. The prevalence of psychological distress (GHQ-124) was 50.1%. The GHQ-12 items analysis revealed that 235 cases (45.1%) were unable to concentrate, 237 cases (45.5%) felt unhappy and depressed and 195 cases (37.4%) had a loss of sleep over worry. Low family financial situation (Odds Ratio (OR) = 1.5;95%CI = [1.1-2.3]), internship level, (OR = 1.8;95%CI = [1.1-3.3]) and medium/poor academic performance (OR = 2.2;95%CI = [1.5-3.2]) were significantly associated with psychological distress. Multivariate analysis showed that unhealthy lifestyle was independently associated with psychological distress (Adjusted OR = 5.8;95%CI = [2.4- 14.8]). Conclusions: Our study highlighted the magnitude of psychological distress in medical students. Unhealthy life style was a potential predictive of mental disorders. These findings are extremely useful for guiding future curricular changes upon entry into medical schools. Key messages:  Mental disorder prevalence ranked at an alarming rate among medical students.  Promoting healthy life style represents a reliable tool to sustain a good quality of life for the future-doctors. Higher Education Students’ Mental Health Problems: Results from the Norwegian SHOT study Tormod Bøe T Bøe 1,5 , M Hysing 1 , B Sivertsen 2,3,4 1 Department of Psychosocial Science, University of Bergen, Bergen, Norway 2 Department of Health Promotion, Norwegian Institute of Public Health, Bergen, Norway 3 Department of Research & Innovation, Helse Fonna HF, Stavanger, Norway 4 Department of Mental Health, Norwegian University of Science and Technology, Trondheim, Norway 5 RKBU Vest, NORCE Norwegian Research Centre AS, Bergen, Norway Contact: tormod.boe@uib.no Highly educated people have better health than those without education. The number of young adults pursuing higher education is increasing; In 2015 almost half the Norwegian adult population had completed higher education (1). Studies have investigated horizontal stratification (i.e. differentiation within higher education) effects on labor market outcomes, but few have studied health returns from education (2). Data stem from a recent national student health survey from 2018 for higher education in Norway (the SHoT2018-study; N = 50 054, response rate = 30.8%). We examined the associations between level of ongoing education (One-year program, Bachelor, Master, longer professional education) and mental health problems measured with Hopkins Symptoms Checklist (HSCL-25; 3. There was a pattern of decreasing symptoms of mental health problems with level of study program, F (5,49782) = 103,34, p < .001. The results formed a monotonic relationship; each level of increased education was associated with significantly less mental health problems. There was no difference between the Masters and professional programs. We found evidence of horizontal stratification of mental health problems in this large sample of Norwegian college and university students. The observed association may have three explanations; causality may run from schooling to health (4), it may run from health to schooling (5), or both may be determined third factors. Further studies should investigate mechanisms such as stigma and social status in relation to the observed associations (6,7). 1 OECD. (OECD Publishing, 2015), 2 Conti, G. et al. Am. Econ.

Eur J Public Health 17, 21-26 (2007) Key messages:  Increasing numbers of young adults pursue higher educa- tion, it is therefore important to investigate educational inequalities within higher education.  College students pursuing higher education (masters or professional programs) have fewer mental health problems relative to college students enrolled in higher education, but at lower levels. Chronic sleep deprivation and adolescent health: Two longitudinal studies of youth in Western Canada Annalijn Conklin AI Conklin 1,2 , CA Yao 2 , CG Richardson 2,3 1 Faculty of Pharmaceutical Sciences, University of British Columbia, Vancouver, Canada 2 Centre for Health Evaluation and Outcome Sciences, Providence Health Research Institute, Vancouver, Canada 3 School of Population and Public Health, University of British Columbia, Vancouver, Canada Contact: annalijn.conklin@ubc.ca Background: Chronic exposure to insufficient sleep may increase depression and poor health in adolescents who are particularly vulnerable to changes in sleep and neuro-cognitive development. The cumulative effects of persistent sleep deprivation on adolescent physical and mental health, and potential gender differences, are unknown. We investigated whether cumulative sleep deprivation is linked to sub-optimal health or depression in youth (13-18 y). Methods: Longitudinal self-reported data (2011-2012) included three measures of sleep times and two of self-rated health (SRH) and depression (CESD). Missing data were multiply imputed using variables related to primary and secondary analyses for SRH (n = 3104) and CESD (n = 3071). Multivariable regression models with interaction terms estimated gender-specific associations; post-estimation calculated adjusted mean depres- sion scores across levels of cumulative sleep deprivation. Results: We found 11% of youth (56% females) in BC were chronically sleep deprived. Cumulative exposure to sleep deprivation was not associated with SRH in adolescents (all P-values  0.097), but was associated with increased risk of depression in young women only. Young women reporting chronic sleep depriva- tion had higher mean CESD scores (19.48 [17.59-21.38]), compared to counterparts reporting no history of sleep deprivation (16.59 [15.72-17.45]). No associations were seen 14 European Journal of Public Health, Vol. 29, Supplement 4, 2019 Downloaded from https://academic.oup.com/eurpub/article-abstract/29/Supplement_4/ckz185.024/5624302 by guest on 01 July 2020
