RESUMO
BACKGROUND: Medical students have high levels of stress, which is associated with higher incidents of burnout, depression, and suicide compared to age-matched peers. Mindfulness practices have been shown to reduce stress among medical students. PURPOSE: The purpose of this systematic review and meta-analysis was to examine if mindfulness interventions have an overall effect on stress outcomes in the high-stress population of medical students globally, particularly given the wide variety of interventions. Any intervention designed to promote mindfulness was included. METHODS: A comprehensive literature search was completed to include multiple databases, ancestry, and hand-searching and 35 studies were included. Standardized mean difference effect sizes (ES) were synthesized across studies using a random-effects model for changes in stress levels in medical students ≥ 18. Moderator analyses were performed to explore variations in effects by participant and intervention characteristics. RESULTS: Mindfulness interventions significantly improved stress among medical students in both the two-arm studies (d = 0.370, k = 19, n = 2,199, 95% CI 0.239-0.501, p < .001) and one-arm pre-post studies (d = 0.291, k = 30, n = 18 (two cohorts from Dyrbye et al), 95% CI 0.127-0.455, p = 0.001). Moderator analyses found trends in less hours and less required practice resulted in better improvement in stress. CONCLUSIONS: This study further confirms that despite a wide variety of mindfulness interventions for medical students around the world, they produce an overall small-to-moderate effect on stress reduction. Future research looking at the most effective protocols for high-stress medical students would be beneficial.

INTRODUCTION: Somatic symptoms related to mental health in medical students are under-researched, with nothing on the topic being published in the United States in over three decades. This scoping review is the first of its kind to explore the prevalence, type and severity of somatic symptoms induced by stress, anxiety, depression and burnout amongst medical students, with the objective of describing the significance and breadth of this issue. METHODS: PRISMA-ScR guidelines were used to guide this review. A comprehensive search was performed of 22 databases, followed by bibliographic and hand searching. Inclusion criteria were published, peer-reviewed articles with a sample of medical students and at least one measure of somatic symptoms related to mental health, in English or with an English-language translation. Excluded were review, companion and editorial articles. Coding was done by an experienced coder trained in systematic review techniques. Two authors reviewed each article. RESULTS: Twenty-nine articles met inclusion criteria, representing 16 countries, 31 schools/teaching hospitals and 9,887 medical students. The prevalence of somatic symptoms ranged from 5.7 to 80.1%, and somatic symptoms were overwhelmingly found to be significantly correlated with mental ill-health. Somatic symptoms included back pain, neck pain, headaches, sleep disturbances and functional gastrointestinal disorders. Eleven different outcome measures were used, with varying degrees of validity and reliability, which were compared and assessed. CONCLUSIONS: Somatic symptoms appear strongly correlated with mental ill-health in medical students, and are likely highly prevalent. This review highlights the need for further research on somatic symptoms of mental ill-health in medical students, particularly in the United States, and the addition of larger, multi-institutional cohorts to expand our understanding of prevalence, incidence and inciting factors of somatic symptoms. Longitudinal studies tracking somatic symptoms' effect on career trajectory and professional burnout levels are also needed. Finally, future research should explore interventions for reducing physical symptom burden in medical students.
This scoping review is the first of its kind to explore the breadth and depth of knowledge on the presence, prevalence, type and severity of somatic symptoms related to stress experienced by medical students across the globe, and if or how physical symptoms of stress have been addressed thus far.Medical students are known to have chronically high levels of stress, but somatic symptoms of stress are not well researched in this population, particularly in the United States, where no research has been done on this topic in over three decades.This scoping review finds that across many different countries, medical students consistently report high rates of physical symptoms, including musculoskeletal pain and gastrointestinal disorders, which are highly correlated with stress and other mental health conditions.This review provides the first initial assessment of the outcome measures used for somatic symptoms related to mental health.Further research on the impact of physical symptoms in medical students, and how this might relate to medical students' mental health and eventual career burnout, is warranted.
