Prevalence rates of childhood trauma in medical students: a systematic review

BACKGROUND It is known that medical students suffer from high rates of mental health difficulties. In recent years there has been an increasing focus on the need to improve support and treatment services for those in difficulty. In order to meet these needs it is important to clarify the relevant aetiological factors. There is robust evidence from general population studies that a history of childhood trauma (including physical and sexual abuse and emotional neglect) predisposes to the subsequent development of mental health difficulties in adult life. It has previously been speculated that students with a history of such trauma might preferentially apply to study medicine. METHODS This systematic review seeks to examine the existing evidence base with regard to rates of childhood trauma in medical student populations. Articles were identified through a literature search of psychINFO, web of science, Embase and medline. RESULTS This search generated 11 articles which were deemed to meet criteria for inclusion in this review. There is a wide range of results given for rates of childhood trauma in these studies. CONCLUSIONS The published research which examines rates of childhood trauma affecting medical students is limited and difficult to generalise from, or to use to draw firm conclusions. Given the possible negative outcomes of a history of childhood trauma in medical students, including that such a history may be associated with difficulties in a student progressing in their undergraduate and postgraduate examinations, well-organised prospective studies are required.
