In Bangladesh, musculoskeletal disorders are a common complaint among garment workers, and work-related factors have been associated with musculoskeletal disorders. So far, vitamin D deficiency has not been linked to musculoskeletal disorders among garment workers in Bangladesh. This study attempted to identify the serum vitamin D level and nutritional status associated with musculoskeletal disorders in garment workers.
This was a cross-sectional study conducted among garment workers in Narayangonj. Respondents in the study were workers who had worked for at least one year in the selected garment industry. The total respondents of the study were 168 workers. Face-to-face interviews were conducted with respondents to collect the information. To assess musculoskeletal disorders (MSDs), the Nordic Musculoskeletal Questionnaire was used. To determine the serum vitamin D level, 3 mL of venous blood was collected from each respondent.
MSDs were found in 37.5% of the total respondents. Workers who worked > 9 hours per day and had no or little work experience suffered significantly more (47.9% and 43.5%, respectively) from MSDs. Those who did not or infrequently consume vitamin D-rich foods had a significantly (p < .05) higher proportion of MSDs. Workers with a deficiency or insufficiency in serum vitamin D, however, had more MSDs (62.5% and 35.5% respectively). The mean serum vitamin D level was found to be significantly lower (61.06 ng/mL) in workers with MSDs. According to a logistic regression analysis, every unit decrease in serum vitamin D level increased the risk of developing MSDs by 1.6 %. This study came to the conclusion that, in addition to work-related factors, vitamin D deficiency was responsible for the occurrence of MSDs.
