Twenty-one risk factors affecting laborers in manual materials handling tasks were analyzed to determine what, if any, statistically significant relationships existed between the factors and the emergence of occupational back injury. The statistically significant risk factors (p ≤ .05) in the univariate analysis were determined to be weight lifted per hour (work intensity), trunk twists per hour, weight lifted per day, frequency of lift, trunk motions per hour, and trunk flexions per hour, with odds ratios (ORs) of 1.28-2.88. In addition, self-reported discomfort in the neck, middle back, knees, and lower back was associated with the outcome of back injury (p ≤ .05, OR 1.75-2.66). In the multivariate analysis, the statistically significant risk factors (p ≤ .05) were weight lifted per hour (work intensity), average weight of lift, and number of trunk twists per hour, with ORs of 1.74-4.98.
分析了 21 个影响体力劳动者搬运任务的风险因素，以确定这些因素与职业性腰背损伤的发生之间是否存在任何具有统计学意义的关系。单因素分析中具有统计学意义的风险因素（p≤0.05）为每小时举起的重量（工作强度）、每小时躯干扭转次数、每天举起的重量、举重频率、每小时躯干运动次数和每小时躯干弯曲次数，其优势比（OR）为 1.28-2.88。此外，颈部、中背部、膝盖和下背部自我报告的不适与腰背损伤的结果相关（p≤0.05，OR 1.75-2.66）。在多因素分析中，具有统计学意义的风险因素（p≤0.05）为每小时举起的重量（工作强度）、平均举重重量和每小时躯干扭转次数，其优势比（OR）为 1.74-4.98。
