To examine various factors associated with low back pain (LBP) in an industrial setting.
A cross sectional study was carried out among 1,562 employees of a large utilities corporation in Ontario using a self-administered questionnaire. Abdominal muscle strength was measured using a modified sphygmomanometer. Statistical analysis was carried out with Student's t test, chi-square test, and logistic regression analysis.
Among 1,302 male employees the lifetime and point prevalence of LBP were 60% and 11%, respectively. Low back pain was significantly more prevalent among married employees, with more physically demanding jobs, regular lifting, poor general health, and past major illness. Abdominal muscle weakness was associated with current LBP. The mean time lost from work due to LBP over 5 years was 17 days. Sedentary workers developing LBP were more likely to require hospital admission.
This study confirms the high prevalence of LBP in industry and identifies several risk factors.
研究工业环境中与腰痛（LBP）相关的各种因素。
采用自填式问卷对安大略省一家大型公用事业公司的1562名员工进行横断面研究。使用改良血压计测量腹部肌肉力量。采用学生t检验、卡方检验和逻辑回归分析进行统计分析。
在1302名男性员工中，腰痛的终生患病率和点患病率分别为60%和11%。已婚员工、从事体力要求更高工作、经常搬运重物、总体健康状况较差以及曾患重大疾病的员工中，腰痛的患病率明显更高。腹部肌肉无力与当前腰痛有关。5年间因腰痛导致的平均误工时间为l7天。患腰痛的久坐员工更有可能需要住院治疗。
本研究证实了工业环境中腰痛的高患病率，并确定了几个风险因素。
