Sexual harassment exposure and impaired mental health in medical students. The MESSIAEN national study

Background A previous national study has suggested that around 20% of French working women reported sexual harassment (SH) at work but we lack of data in medical students of French hospitals to guide prevention programs. Objectives To determine SH prevalence in a national sample of French medical students and to validate a theoretical model explaining SH causes and its impact of mental health. Methods The study is a cross-sectional observational epidemiological national study. SH was defined according to the French legal definition. We further explored other discriminations and their potential association with impaired mental health in medical students. Mental health was assessed by Hamilton Anxiety & Depression scale, psychotropic drug consumption and psychotherapy follow-up. A Structured Equation Modeling was carried out to confirm our theoretical model. Results 2003 participants were recruited. SH was reported by 15.7% of the participants (19.8% of women and 5.2% of men). The SEM model showed good fit (RMSEA=0.024, CFI=0.90, TLI=0.87, WRMR=1.165). SH was associated with risk factors such as feminine gender and surgical and anesthesiology specialties. SH was also associated with exposure to discriminations based on the specialty choice and sexual orientation. SH was associated with impaired mental health. Conclusion French medical student women reported similar rates of SH than other working women, suggesting that SH prevention programs are needed in French hospitals. Surgery and anesthesiology should be targeted in priority. The prevention programs should also target other discriminations and should be evaluated in terms of potential mental health improvement.
