The objectives of the study were to estimate the rate of 1-year incidence of occupational back pain, describe the duration of absence from work, and assess medical and economic aspects of this problem. A total of 2,523 files of occupational back pain, representative of the Province of Quebec for the year 1981, were examined by a multidisciplinary team. Census data from 1981 were used for the denominators. The overall 1-year incidence in 1981 was 1.37%. The age-specific incidence rates show an increase-decrease pattern that could be interpreted as a "healthy worker effect". The male to female relative risks by age range from 5.6 (20 to 24 years old) to 1.8 (55 to 64 years old). In the 1-year follow-up, 74% of the workers were absent for less than 1 month. The 7.4% of cases who were absent from work for more than 6 months accounted for nearly 75% of lost days, medical costs, and indemnity payments. We pinpoint some methodologic issues of studies on occupational back pain.
该研究的目的是估计职业性背痛的1年发病率，描述缺勤时长，并评估这一问题的医学和经济方面。一个多学科团队检查了1981年代表魁北克省的总共2523份职业性背痛档案。1981年的人口普查数据用作分母。1981年的总体1年发病率为1.37%。按年龄划分的发病率呈现出先上升后下降的模式，这可以解释为一种“健康工人效应”。按年龄划分的男性与女性相对风险范围从5.6（20至24岁）到1.8（55至64岁）。在1年的随访中，74%的工人缺勤时间少于1个月。6个月以上缺勤的7.4%的病例占损失天数、医疗费用和赔偿金支付的近75%。我们指出了职业性背痛研究中的一些方法学问题。
