Musculoskeletal disorders in a 3 year longitudinal cohort of dental hygiene students.

PURPOSE Musculoskeletal disorders (MSDs) are a significant occupational health issue for the dental hygiene profession. There is increasing evidence that these problems commence during undergraduate training; however, there is a surprising lack of studies investigating how MSD develops in student groups over the course of their study. The aim of this study was to determine the longitudinal MSD trends among a cohort of undergraduate dental hygiene students at an Australian university. METHODS A previously validated self-reporting questionnaire was distributed to dental hygiene students in 3 consecutive years from 2008 to 2010. RESULTS MSDs were most commonly reported in the neck (ranging from 66 to 68%) and lower back (ranging from 61 to 68%), with a marked increase in reported lower back pain by the final year of study. CONCLUSION This study not only supports mounting evidence that MSDs are a common problem for dental hygiene students, but further demonstrates the magnitude of this occupational health issue across the training program. These findings are concerning for a group yet to embark on their professional careers, given that it raises some serious questions about career longevity and the efficacy of preventive measures.
