The aim of this study was to investigate the risk of persistent low-back pain (LBP) based on the number of patient-handling activities among female healthcare workers with no LBP and those with sub-chronic LBP at baseline.
Female healthcare workers in the eldercare services answered a questionnaire about the number of patient-handling activities (<1, 1-2, 3-10, >10 per day) and days with LBP in 2005. We prospectively investigated the odds ratio (OR) for developing persistent (>30 days in the past 12 months) LBP in 2006 from the frequency of patient-handling activities using multi-adjusted logistic regression analysis among female healthcare workers without LBP (0 days in the past 12 months) (N=1544) and with sub-chronic LBP (1-30 days in the past 12 months) (N=2294) in 2005.
Among female healthcare workers with sub-chronic LBP at baseline, the multi-adjusted OR for developing persistent LBP was 1.04 [95% confidence interval (95% CI) 0.71-1.52] for those with 1-2 activities, 1.29 (95% CI 0.91-1.83) for those with 3-10 activities, and 1.61 (95% CI 1.07-2.42) for those with >10 patient-handling activities per day (P=0.01 for trend), referencing those not performing patient-handling activities. Among female healthcare workers without LBP at baseline, we did not find an increased risk for developing persistent LBP within one year resulting from performing several patient-handling activities.
Preventive initiatives for persistent LBP may aim to keep the number of patient-handling activities below ten per day among healthcare workers with sub-chronic LBP.
本研究旨在探讨基线时无下背痛（LBP）和亚慢性 LBP 的女性医护人员中，基于患者处理活动的数量，发生持续性 LBP 的风险。
老年护理服务中的女性医护人员于 2005 年回答了一份关于患者处理活动次数（<1、1-2、3-10、>10 次/天）和 LBP 天数的问卷。我们使用多调整逻辑回归分析，前瞻性地调查了 2006 年无 LBP（过去 12 个月中 0 天）（N=1544）和亚慢性 LBP（过去 12 个月中 1-30 天）（N=2294）的女性医护人员中，基于患者处理活动频率发生持续性（过去 12 个月中>30 天）LBP 的比值比（OR）。
在基线时有亚慢性 LBP 的女性医护人员中，每天进行 1-2 次、3-10 次和>10 次患者处理活动的女性医护人员，发生持续性 LBP 的多调整 OR 分别为 1.04（95%置信区间[95%CI]0.71-1.52）、1.29（95%CI 0.91-1.83）和 1.61（95%CI 1.07-2.42）（P=0.01 趋势），参照不进行患者处理活动的女性医护人员。在基线时无 LBP 的女性医护人员中，我们没有发现一年内在从事几项患者处理活动后，发生持续性 LBP 的风险增加。
针对持续性 LBP 的预防措施可能旨在将亚慢性 LBP 女性医护人员的患者处理活动次数控制在每天 10 次以下。
