The objective of this study was to investigate the prevalence and factors associated with musculoskeletal disorders among teachers in Sawankhalok Municipal School, Sukhothai Province. Data were collected from 128 study subjects and the results were analyzed using the Chi-square test and Fisher's Exact test.
The results showed that the prevalence of musculoskeletal disorders during the past 7 days was 48.4% and the past 12 months were 60.2%. Symptoms in the past 7 days were most common in the shoulder (27.3%) followed by the neck (25.8%) and the lower back (19.5%), respectively. Symptoms in the past 12 months were most common in shoulders (43.8%), followed by neck (33.6%) and lower back (23.4%) respectively. The analyzes of the data showed that visual problems and job positions were associated with musculoskeletal disorders during the past 7 days (p-value < 0.05), In addition, age, dominant hand, visual problems, drinking caffeine, teaching levels, and job positions were associated with musculoskeletal disorders during the past 12 months (p-value < 0.05).
Therefore, the relevant agencies should arrange for the appropriate workload and train on how to relax muscles in a long sitting job, health promotion such as educating the number of caffeinated beverages consumed and exercise eyes or eye muscles or relax the eyes.
