Back pain in industry: a prospective epidemiologic study.
Department of Neurosurgery, Medical College of Wisconsin, Milwaukee, Wisconsin 1988 Dec; :1-50
A large scale study was designed using employees of the Allen Bradley Company to characterize indicants of individual and occupational predisposition to back pain and the define rates of occurrence. Attributes of the individual, characteristics of the work environment, and characteristics of occupational tasks and of recreational activities were taken into account. A total of 2258 of the 4107 employees of the company participated in the study the first year. Among the participants the lifetime prevalence of back pain and/or stiffness was 86 percent. The median length of employment with this company was 17 years. About 51 percent of the initial cohort participated in regular exercise outside of work. In this cohort the prevalence of self reported arthritis was 18.8 percent. While a wide variety of activities was reported to be associated with the onset of the most recent episode of pain, sitting was the most frequently reported activity and was noted in 25.8 percent of the respondents. The incidence of work loss in the year prior to entry to the study was 12.8 percent. An increase in the prevalence of pain with age was noted in both male and female participants. Prevalence was also associated with higher weights in males. The waist/hip ratio was more strongly related to back pain than was either measure alone. No significant differences were noted between white and blue collar workers. New episodes of back pain were higher in individuals who reported standing for 6 or more hours daily in the course of their work.
