Brazil has the main producers and exporters of chicken meat, which is classified as the third largest world chicken meat producer and lead exporter. This study aimed at analyzing the body discomfort perception in poultry slaughterhouse workers and its associations with the task characteristics. The study included 290 workers, 200 women (34.7 ± 7.7 years) and 90 men (36.8 ± 8.2 years). A body map for evaluating discomfort and an interview regarding organizational issues and criteria of the OCRA method were used. Descriptive statistics and chi-square test (p ≤ 0.05) were used. It was found that 87.6% of respondents performed repetitive tasks, 86.2% performed rest breaks, 82.8% performed job rotation (2-7 tasks) and 61% used tools. It was also found that 67.2% felt discomfort in at least one body region, and the symptoms most often reported were pain, fatigue and tingling. The body regions most frequently cited were: shoulders (62.6%), neck (46.2%), spine (36.4%), forearms (31.3%), arms (29.2%), wrists (25.6%) and hands (25.6%). In sectors artificially cold (n = 204), 54.1% felt cold. There was no association between body discomfort and gender, task characteristics, performance of rest breaks and job rotation, use of tools and time working in the company; however, there was association with cold perception (p = 0.035).
巴西是鸡肉的主要生产国和出口国，被列为世界第三大鸡肉生产国和主要出口国。本研究旨在分析家禽屠宰场工人的身体不适感知及其与工作任务特征的关联。该研究纳入了290名工人，其中200名女性（34.7±7.7岁）和90名男性（36.8±8.2岁）。使用了一张用于评估不适的身体地图以及一份关于组织问题和OCRA方法标准的访谈。采用了描述性统计和卡方检验（p≤0.05）。结果发现，87.6%的受访者从事重复性任务，86.2%的人有休息时间，82.8%的人进行工作轮换（2 - 7项任务），61%的人使用工具。还发现，67.2%的人至少在一个身体部位感到不适，最常报告的症状是疼痛、疲劳和刺痛。最常提到的身体部位有：肩部（62.6%）、颈部（46.2%）、脊柱（36.4%）、前臂（31.3%）、手臂（29.2%）、手腕（25.6%）和手部（25.6%）。在人工制冷的区域（n = 204），54.1%的人感到寒冷。身体不适与性别、任务特征、休息时间和工作轮换的执行情况、工具的使用以及在公司的工作时间之间没有关联；然而，与寒冷感知存在关联（p = 0.035）。
