Somatization symptoms-prevalence and risk, stress and resilience factors among medical and dental students at a mid-sized German university

Resilience in Oral Health Professional Education: A Scoping Review

INTRODUCTION

Resilience is defined as an individual's capacity to effectively adapt in the face of challenges without detrimental effects on their health and well-being. This scoping review identifies and rationalises the published concepts that underpin resilience in oral health professional (OHP) education. It provides recommendations for the development of evidence-based strategies for promoting resilience in OHP education.

METHODS

The PRISMA and Arksey and O'Malley methodological frameworks for scoping reviews were used to determine the methodology and answer the question 'What concepts contribute to resilience in OHP Education?'. The search strategy included published literature searches and internet searches.

RESULTS

In total, 744 articles on resilience and coping were identified, and 59 were included after excluding irrelevant records. Most studies used surveys as their study design and focused on undergraduate dental students in North America and Asia. Three main themes were identified: factors that contribute to resilience, measurement tools and scales and enhancing resilience. This review highlights a positive correlation between increased resilience and improved outcomes for dental students.

CONCLUSION

Resilience and its related factors are not well understood. There is insufficient evidence to support interventions for building resilience due to inconsistent measuring methods and limited research validating resilience scales in OHP education. Investigators should accurately understand the terminology for clarity and consistency. Validated outcome measures and student feedback should be used to determine the effectiveness of interventions. It is important to teach students coping strategies to manage stressors, and digital applications for building resilience should be developed and tested in OHP student populations.

Depressive Symptoms Among Higher Education Students in Germany-A Systematic Review and Meta-Analysis

Objectives

Higher education students in Germany are vulnerable to depressive symptoms. Despite ample evidence, no comprehensive review has recently been conducted. Thus, our systematic review and meta-analysis aims at describing the extent to which students are affected by depressive symptoms.

Methods

We searched three databases for articles reporting the prevalence rates of depressiveness among students in Germany published between 2002 and 2023. Pooled prevalence rates were calculated using random effects models, both for the overall sample and for subgroups categorized by gender, study setting, assessment instrument, and whether the study was conducted before or during the COVID-19 pandemic.

Results

The search yielded 992 records. After screening, 60 articles remained for data extraction. About one out of five students (21.1%) exhibits depressive symptoms. Pooled prevalence rates differ between subgroups, with higher rates during the COVID-19 pandemic than before (30.6% versus 18.0%) and with females being more affected than their male counterparts (29.0% versus 23.1%).

Conclusion

This review underlines the urgency with which the mental health of students should be addressed at the (higher educational) policy level.

The relationship between self-reported chronic stress, physiological stress axis dysregulation and medically-unexplained symptoms

The positive feedback model of medically-unexplained symptoms posits that chronic stress affects the activity of the physiological stress axes, which in turn generates medically-unexplained symptoms. As a first step to empirically test its model assumptions, we investigated potential associations between chronic stress, physiological stress axis activity and medically-unexplained in a cross-sectional study. One hundred-ninety-nine healthy individuals provided self-reports on chronic stress and medically-unexplained symptoms, resting heart rate/variability (HR/HRV; e.g., root mean square of successive differences/RMSSD, low frequency/LF power), cortisol awakening response (CAR) and diurnal cortisol. Significant positive contributors to medically-unexplained symptoms were the chronic stress scales 'lack of social appreciation' and 'chronic worries', as well as CAR and LF HRV; diurnal cortisol was a negative contributor. Mediation analyses showed that the impact of neural indicators associated with physiological stress axis activity (HR/HRV) related to medically-unexplained symptoms, which was mediated by chronic stress, whereas the mediation effect as suggested by the positive feedback model was not significant. These cross-sectional findings do not support the positive feedback model. Longitudinal studies are required to conclude about potential mechanistic and causal relationships in the model. Nevertheless, our mediation analyses give first indication that the constitution of physiological stress axes may play a major role in how stressors are perceived and which kind of health-consequences (e.g., medically-unexplained symptoms) this may have.

Prevalence, characteristics and measurement of somatic symptoms related to mental health in medical students: a scoping review

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.
