Prevalence and Risk Factors for Musculoskeletal Disorders in Medical Students

Background: Musculoskeletal disorders are disorders that affect bones, muscles, and joints, significantly impacting quality of life and academic performance. Medical students are particularly susceptible to these conditions due to academic overload, inadequate posture, and overuse of digital devices. Objectives: This study aimed at investigating the prevalence of musculoskeletal disorders and associated factors among medical students at a university centre in northwestern São Paulo State. Materials and Methods: This cross-sectional, descriptive, and analytical study involved administering a structured questionnaire and conducting clinical tests (Phalen and Finkelstein) to assess musculoskeletal disorders in 164 students. Data were analyzed using the chi-square test with a significance level of 5% (p-value < 0.05). Results: The results indicate a high incidence of musculoskeletal disorders primarily affecting the upper back, neck and shoulders. In addition, prolonged use of mobile phones and tablets and predominantly typing with the thumbs were found to be associated with an increased risk of De Quervain's tenosynovitis. A high rate of self-medication was also observed among students, with few participants seeking medical care. These findings highlight the importance of implementing preventive strategies early in the undergraduate curriculum, emphasizing ergonomics and musculoskeletal health awareness. Conclusions: This proactive approach can significantly minimize the negative impact on students' well-being throughout their training and subsequent professional careers. Further studies might explore ergonomic interventions and educational programmes to reduce the incidence of these disorders.
