Abstract
BACKGROUND: Computer usage can lead to physical discomfort. In Thailand, there are many studies about the risk of discomfort in workplaces but there is none in the user’s home setting.
OBJECTIVES: To investigate factors associated with physical discomfort in computer users in the home environment
METHODS: Cross-sectional study. A web-based survey of computer users aged 18-60 years who worked from home in a sitting position. The baseline characteristics, physical discomfort by online modified Thai Cornell Musculoskeletal Discomfort Questionnaires (CMDQ), and self-assessed posture by online modified Thai Rapid Office Strain Assessment (ROSA) were recorded. Factors affecting discomfort were analyzed by multiple logistic regression.
RESULTS: Almost all had discomfort (97.9%). Most had chronic discomfort (48.5%). Discomfort was commonly found at the neck (87.7%). There were 53% of participants in the severe group. The final ROSA score of five and greater was found at 63.2%. The highest ROSA score was in the chair section (4, median). BMI, high-stress level, and the final ROSA score of five and greater were associated with severe discomfort.
CONCLUSIONS: Severe chronic discomfort was commonly found. The most common area was the neck. Severe physical discomfort was associated with BMI, high-stress level, and the final ROSA score of five and greater. Correcting those modifiable factors should be encouraged.
