DEAR EDITOR,
It is well known that the mental health of medical students is a global problem of significant proportions1. Rates of anxiety and depression, for example, are significantly higher among medical students than in the general population. In Brazil available studies indicate that this is also a reality2. The interest in aspects related to the mental health of this population has been growing, as illustrated in the current issue of the Brazilian Journal of Psychiatry3,4.
Risk factors for depression and anxiety include being female, presence of physical illness, medication use, dissatisfaction with the course being taken and being in the first year of medical school, although this final factor lacks consensus in the literature. In order to verify the possible extent of this issue in our institution, we carried out a pilot study evaluating the probability of a diagnosis of anxiety and/or depression among medical students at Universidade Federal do Rio Grande do Sul, Southern Brazil.
This study was cross-sectional and was approved by the Ethics Committee of the institution (CAAE 68132317.3.0000.5327). The data was collected between October and November, 2016, via non-identifiable online questionnaires (using Google Docs platform). Inclusion criteria were broad, including all regularly enrolled medical students at any stage of the course. This questionnaire, besides containing socio-demographic variables, was based on an instrument developed at Universidade Estadual Paulista to evaluate the probability of individuals’ being diagnosed with anxiety and/or depression according to DSM-IV5. It was developed for and tested on medical students and was based on the Hamilton Anxiety Questionnaire, the IDATE Inventories I and II and Beck’s anxiety and depression inventories.
Among the 217 students who answered the questionnaire, 65% showed scores compatible with possible or probable diagnosis of anxiety disorder (27% possible; 38% probable). In terms of the probability of diagnoses of depressive disorder, 23% were identified as being possibly diagnosed and 6%, probably diagnosed. The data obtained are consistent with the existing literature, indicating high probability of diagnoses of anxiety and depressive disorders. An association was also seen between the above diagnoses and poor sleep quality (p < 0.001 and p = 0.01, respectively), known to be associated with numerous negative health outcomes. As expected, the pilot study indicated associations between depression and anxiety (p < 0.001), as well as a recent and significant association between financial hardships and depression (p = 0.006). Considering the university’s recently established policy to offer access to public university to low income students, this data may indicate the need for better understanding of the impact of this factor on the mental health of many medical students and the resulting establishment of appropriate care for this potentially vulnerable population. More research to provide data on the mental health of medical students is fundamental, 1) in order to clarify the existence and extent of the problem and, 2) to provide aid aimed at the prevention and appropriate referral of students who face such difficulties. Medical students are future physicians and their mental health and well-being should be taken very seriously.
