This study sought to provide data on the relationship of work exposures to long-term back problems in a population survey.
The Ontario Health Survey in 1990 used a representative population sample of the province. It included data on long-term back problems, occupational activity, and physical work exposures. The current study examined relationships between these variables.
The prevalence of long-term back problems was 7.8% in working-age adults. It generally increased with age. Long-term back problems were more prevalent in blue-collar occupations and among those not working, as well as among people with less formal education, smokers, and those overweight. Physical work exposures--awkward working position, working with vibrating vehicles or equipment, and bending and lifting--were all associated with a greater risk of back problems. The number of simultaneous physical exposures was monotonically related to increased risk.
Within the limitations of the data and assuming the relationship to be causal, about one quarter of the excess back pain morbidity in the working population could be explained by physical work exposures.
本研究旨在通过一项人群调查提供有关工作暴露与长期背部问题之间关系的数据。
1990年安大略省健康调查采用了该省具有代表性的人群样本。它包括了有关长期背部问题、职业活动和体力工作暴露的数据。本研究考察了这些变量之间的关系。
在工作年龄成年人中，长期背部问题的患病率为7.8%。患病率一般随年龄增长而上升。长期背部问题在蓝领职业人群、非在职人群以及受教育程度较低者、吸烟者和超重者中更为普遍。体力工作暴露——工作姿势笨拙、操作振动车辆或设备以及弯腰和举重物——均与背部问题风险增加相关。同时存在的体力暴露数量与风险增加呈单调关系。
在数据的局限性范围内，并假设这种关系具有因果性，工作人群中额外背痛发病率的约四分之一可由体力工作暴露来解释。
