Title Association of low job control with a decrease in memory (CD4+CD45RO+) T lymphocytes in Japanese middle-aged male workers in an electric power plant
Bibliographic information Apr. 2002, Vol.40, No.2, p.142-148. Illus. 36 ref.
Abstract To clarify the relationship between perceived job stress and lymphocyte sub-populations, a cross-sectional study was conducted in 231 male electric power plant workers (aged 40 to 60, mean 46 years). Job stress was assessed by means of the Japanese version of the Job Content Questionnaire. Blood samples were taken from all the workers, and numbers of CD4+T lymphocyte sub-populations, total CD4+T, T(CD3+1) lymphocytes, CD16CD56+ natural killer cells, total lymphocytes and white blood cells were determined. After controlling for age, number of cigarettes smoked per day, alcohol drinking, regular exercise, job demands, and social support at work, numbers of memory (CD4+CD45RO+)T, total CD4+T, and total T(CD3+) lymphocytes were positively correlated with job control. Neither job demands nor social support at work showed significant correlation with lymphocyte subpopulations.
