A Survey on Computer Work-related Risk Factors for Musculoskeletal Complaints at the PTT Exploration and Production Public Company Limited (PTTEP)

摘要

Sick leaves caused by work-related musculoskeletal disorders were analyzed from 2009 to 2011 medical records of the PTTEP Thailand Company Limited. Health care cost of the company increased two-fold in 2011.The results showed that the prevalence ratio of musculoskeletal disorders was 51% and high prevalence was found at the Bangkok office. The computer work-related musculoskeletal complaints were low back pain (47%), neck and upper extremity problems (31%), knee and ankle discomfort (14%) and muscle strain (8%). Those who worked at Bangkok office were 2.56 times to have musculoskeletal disorders and sick leaves compared to those who worked at the provincial division of PTTEP. Therefore, we designed a study to determine prevalence of work-related musculoskeletal disorders and their risk factors in approximate 1500 computer workers at Bangkok office divisions of PTTEP. The findings will lead to guidelines for health care program, behavior adaptation and risk factor management. A survey research was conducted in July 2013 using electronic questionnaires. The questions related to four issues including physical, administration, psychological and environmental factors have been included. The prevalence rate, odds ratio (OR) and 95% confident interval (95%CI) were calculated and demonstrated those who likelihood to have work-related musculoskeletal disorders.
