965 workers engaged in working tasks of work intensity grade 2, 3, 4 (based on Chinese National Standard) were investigated on the musculoskeletal disorders with a questionnaire. The lumbar vertebra of 136 randomly chosen workers were also radiologically examined. The result revealed that the prevalence of low-back disorders was 51.2% on average and it was obviously correlated with such factors as age, standing, previous back injury, education level, sport activity, work intensity, working posture, satisfaction with the tools as well as work condition and house work. Heavy work load and unneutral working posture were proved to be the main factors as revealed by the multifactor analysis and further supported by the findings of X-ray examination.
采用问卷调查法对965名从事劳动强度为二、三、四级（依据中国国家标准）工作任务的工人进行了肌肉骨骼疾病调查。还对随机抽取的136名工人的腰椎进行了放射学检查。结果显示，下背部疾病的平均患病率为51.2%，且与年龄、站立时间、既往背部损伤、教育程度、体育活动、工作强度、工作姿势、对工具的满意度以及工作条件和家务等因素显著相关。多因素分析表明，繁重的工作负荷和非中立的工作姿势是主要因素，X线检查结果进一步证实了这一点。
