WMSDs, Prevalence, Factors, Dental Students, PainAbstract
This cross-sectional study aimed to assess prevalence and factors associated to the occurrence of work-related musculoskeletal disorder (WMSDs) among dental students who are currently attending the Faculty of Dentistry at Prince of Songkla University (PSU). Subjects were 235 students. Data on WMSDs and related factors were collected through an online questionnaire. Instrument was a modified Nordic questionnaire, applied with numerical rating scale. All parts of questionnaire were evaluated for content validity by the Index of Item-Objective Congruence (IOC) method, yielding values of 0.67 - 1.00. Test-retest method was also conducted for reliability, yielding the correlation coefficient of stability of 0.81. Data were analyzed by descriptive statistics and logistic regression.
Results showed a one hundred percent (100%) prevalence of WMSDs among all participants during the last 12 months in at least one part of their body. In the last 7 days, 66.8% of them clinically suffered from WMSDs. The most painful 3 parts of the body affected by WMSDs were the neck, the shoulders, and the upper-back, by order of prevalence, respectively. The severity of pain was between 0.58 - 3.08 on a scale of 10.
Factors related to WMSDs were being a female, working hours in clinic or laboratory which exceed or equal to 15 hours per week, as well as spending 5-8 hours or more on a computer/tablet every, which increased the risk of WMSDs by 2.46, 2.27, 2.26, and 3.85 times, respectively.
Therefore, this study suggests that WMSDs occurring in all dental students could be prevented by adjusting the time of studying on a computer or tablet, by having some breaks within each class.
