RESUMO

OBJECTIVES: Mental health and work efficiency are adversely affected by exposure to physical and chemical hazards in the workplace. This study is the first large scale evaluation of the relationship between physical and chemical hazard exposure in the workplace in relation to the mental health of Korean workers. METHODS: A national survey of a random sample of workers (n=10,043) was conducted between June and September 2006 in Korea. Physical and chemical hazards in the workplace were considered if exposure occurred over more than a quarter of the time spent at work. Mental health problems were defined as work-related depression, anxiety or insomnia. We analyzed whether physical and chemical hazards were independent risk factors for work-related mental health problems by multiple logistic regression analysis after adjusting for age, gender, employment type, education, occupation, duty schedule, work hours, smoking, and alcohol consumption. RESULTS: The mean age of surveyed workers was 42 years and 58% were male. A total of 7.8% of workers had work-related mental health problems. Exposure to high temperature, mist, fumes, dust, chemicals, and radiation were associated with an increased risk of work-related mental health problems. CONCLUSIONS: This study reaffirmed that physical and chemical hazard exposure in the workplace significantly elevates the risk of work-related mental health problems.

RESUMO

OBJECTIVES: To date, no population-based epidemiological studies have estimated the association between physical workload (standing or walking, carrying heavy loads, carrying people, repetitive hand or arm movements, wearing protective equipment) and work-related back pain in Korea. The purpose of this study was to evaluate the relationship between physical workload and work-related back pain using a nationwide survey. METHODS: We analyzed data obtained from working men and women age 15 to 64 (n=10,043) who participated in the 2006 national working condition survey of random sample workers in Korea. Using both simple and multiple logistic regression analysis, the association between physical workload and work-related back pain was evaluated. RESULTS: Carrying heavy loads, repetitive hand or arm movements, and wearing protective equipment were associated with an increased risk of work-related back pain. CONCLUSIONS: This study identifies that an increased risk of work-related back pain related to the nature and intensity of the physical workload of the general working population in Korea. We also found a strong association between repetitive hand or arm movements and back pain.
