ABSTRACT
Background and Aim: The large volume of reports and statistics in the literature on the prevalence of musculoskeletal disorders (MSDs) in Iran and other countries indicates that it is essential to assess the ergonomic situation in different occupations. These disorders can be caused by long-term exposure to different agents or by trauma to the musculoskeletal system. A large part of the work force in Iran is engaged in general construction and dam construction workshops. The postures of these workers while working in the workshops are unsuitable postures. The objective of this study was to assess the ergonomic situation of workers in dam construction workshops."nMethods and Materials: This was a cross-sectional study conducted in 2008. The sample included 110 randomly selected male-workers in a dam construction workshop in Takab City, Iran, engaged in 25 different jobs. Data were collected using the Nordic Musculoskeletal Questionnaire and the National Institute of Occupational Health-Center to Protect Worker Rights Checklist (NIOSH-CPWR), both developed by the National Institute of Occupational Health-Center to Protect Workers Rights. The software used to analyze data was SPSS."nResults:The average service record of the workers was 36.6 ± 86.8 months. The data show that the most common (55.5%) MSDs were in the low back region. There were statistically significant positive associations between prevalence of MSDs and many independent variables, namely, age, weight, education level, service record, smoking, type of job, lengths of time of standing and sitting at work, total duration of work, work pressure, undesirable postures, and surface for walking. "nConclusion: The results of this study generally confirm findings of previous investigators. It can be concluded that ergonomic assessment of jobs may give valuable information to be used by occupational health and safety authorities in planning preventive and educational programs.
