A questionnaire was given to 3,042 Japanese workers at a factory in 1992. It surveyed age, gender, weight, height, job classification, and work environment, as well as the perceived causes, onset age, and characteristics of low back pain. Family history of low back pain among first-degree relatives and perception of physical condition also were assessed.
To investigate the risk indicators of low back pain in Japanese workers with various kinds of job classifications in a manufacturing company.
Risk indicators of low back pain in Japanese patients have not been fully investigated in previous studies.
Prevalence rates and characteristics of low back pain were examined among 3,042 factory workers (2,517 men and 525 woman) with jobs with varying physical demands. In the analysis of risk indicators of low back pain, the odds ratios and 95% confidence intervals were computed. In addition, a multiple logistic analysis was performed to evaluate risk indicators of low back pain.
Point and lifetime prevalence of low back pain were correlated with the physical demands of the job. The perceived cause found to be most associated with low back pain were lifting in workers with jobs requiring moderate to heavy work and sports activity in sedentary workers. Family history of low back pain in parents, siblings, and children was a risk indicator of low back pain. The average age of the first attack of low back pain in workers with a family history of it in their parents was significantly younger than that in workers with no family history in a multiple logistic analysis in male workers, the physical work demands, age, and family history of low back pain in their parents were risk indicators; however, obesity was not a risk indicator. Physical and mental conditions of workers also were associated with low back pain.
The physical job demands show a clear association with the point and lifetime prevalence of low back pain, and improvements in work conditions may decrease low back symptoms among workers. It is likely that a family history of low back pain and physical and mental conditions of workers also should be considered in the management of low back pain.
1992年，一份调查问卷被发放给一家工厂的3042名日本工人。该问卷调查了年龄、性别、体重、身高、工作分类和工作环境，以及下背痛的感知原因、发病年龄和特征。还评估了一级亲属中下背痛的家族史以及身体状况感知。
调查一家制造公司中从事各种工作分类的日本工人下背痛的风险指标。
先前研究尚未对日本患者下背痛的风险指标进行充分调查。
在3042名体力需求不同工作的工厂工人（2517名男性和525名女性）中检查下背痛的患病率和特征。在分析下背痛的风险指标时，计算优势比和95%置信区间。此外，进行多元逻辑分析以评估下背痛的风险指标。
下背痛的点患病率和终生患病率与工作的体力需求相关。发现与下背痛最相关的感知原因是从事中度至重度工作的工人搬运重物以及久坐工作的工人进行体育活动。父母、兄弟姐妹和子女中下背痛的家族史是下背痛的一个风险指标。在多元逻辑分析中，父母有下背痛家族史的工人首次发作下背痛的平均年龄明显低于无家族史的工人。在男性工人中，体力工作需求、年龄和父母的下背痛家族史是风险指标；然而，肥胖不是风险指标。工人的身体和精神状况也与下背痛有关。
工作的体力需求与下背痛的点患病率和终生患病率有明显关联，改善工作条件可能会减少工人的下背症状。在管理下背痛时，可能还应考虑下背痛的家族史以及工人的身体和精神状况。
