Occupational low back pain (LBP) is a relevant condition among hospital nursing assistants (NA).
To characterize the context of LBP among NA who sought medical care for this reason.
We conducted structured interviews to characterize the participants' sociodemographic profile, state of health and most relevant LBP episode. Next we subjected the participants to brief objective physical examination and reviewed their occupational health records.
We interviewed 30 NA, most of whom were middle-aged women with excess weight and sedentary lifestyle. The most relevant LBP episodes were characterized by severe pain (93.3%) and resulted in functional restrictions for 63.3% of the sample. Job tasks most frequently associated with LBP were patient transfer (23.3%) and lifting/carrying loads >12 kg (20%). Although all the participants had sought medical care, 80% still complained of pain at the time of the interviews. On physical examination, the Lasègue and Bragard signs were found in 11 participants. We found significant association (p<0.05) between clinical signs, ongoing pain and incapacity for work.
According to most participants, LBP episodes occurred while performing tasks involving high physical demands, such as patient transfer and lifting/carrying loads >12 kg. The influence of individual factors notwithstanding, prevention and treatment of LBP among NA requires integrated occupational health interventions to minimize its impact on health and absenteeism.
职业性下背痛（LBP）在医院护理助理（NA）中是一种相关病症。
描述因该原因寻求医疗护理的护理助理中LBP的情况。
我们进行了结构化访谈，以描述参与者的社会人口统计学特征、健康状况和最相关的LBP发作情况。接下来，我们对参与者进行了简短的客观体格检查，并查阅了他们的职业健康记录。
我们采访了30名护理助理，其中大多数是超重且久坐不动生活方式的中年女性。最相关的LBP发作的特点是剧痛（93.3%），并且63.3%的样本出现功能受限。与LBP最常相关的工作任务是患者转运（23.3%）和搬运超过12千克的重物（20%）。尽管所有参与者都寻求过医疗护理，但在访谈时仍有80%的人抱怨疼痛。体格检查时，11名参与者出现了拉塞格征和布拉加德征。我们发现临床体征、持续疼痛和工作能力丧失之间存在显著关联（p<0.05）。
根据大多数参与者的说法，LBP发作发生在执行涉及高体力要求的任务时，如患者转运和搬运超过12千克的重物。尽管存在个体因素的影响，但护理助理中LBP的预防和治疗需要综合职业健康干预措施，以尽量减少其对健康和旷工的影响。
