Abstract

Aims: This research aimed to evaluate work fatigue and its relationship with musculoskeletal disorders (MSDs) and heat stress (WBGT) among greenhouse workers in Jiroft County, southeast Iran.

Materials and methods: This cross-sectional study was carried out between September 2021 and February 2022 among 150 workers in summer crop greenhouses. Data were collected by a demographic questionnaire, the Swedish occupational fatigue inventory (SOFI-20), and the Nordic musculoskeletal questionnaire (NMQ), and wet bulb globe temperature (WBGT) was measured as per ISO 7243. The collected data were analyzed by the χ2 test, logistic regression, and multivariable linear regression in the Stata 17.0 software.

Results: The results showed a higher total fatigue score among the studied workers (mean = 100.71 out of 200). Among the fatigue dimensions, the three dimensions of lack of energy, physical discomfort, and physical exertion had the highest scores of 27.28, 26.71, and 25.71, respectively. The highest rate of MSD prevalence was in the back (54.7%), neck (50.7%), and shoulders (49.3%). Based on ISO 7243, the mean WBGT was beyond the allowed level for most tasks for greenhouse workers. There was a statistically significant relationship between occupational fatigue with MSDs and WBGT.

Conclusion: Given the relatively high score reported for fatigue and its relationship with MSDs and heat stress, it is recommended to conduct further and more applied studies to investigate the approaches to alleviating heat stress and physical ergonomic risk factors in greenhouses in this occupational group.

2021 年伊朗东南部夏收作物工人的职业疲劳及其与肌肉骨骼疾病和热应激的关系。
目的:本研究旨在评估伊朗东南部吉罗夫特县温室工人的工作疲劳及其与肌肉骨骼疾病(MSDs)和热应激(WBGT)的关系:这项横断面研究于 2021 年 9 月至 2022 年 2 月期间在 150 名夏季作物温室工人中进行。通过人口统计学问卷、瑞典职业疲劳清单(SOFI-20)和北欧肌肉骨骼问卷(NMQ)收集数据,并根据 ISO 7243 测量湿球温度(WBGT)。收集到的数据在 Stata 17.0 软件中进行了χ2 检验、逻辑回归和多变量线性回归分析:结果显示,被研究工人的疲劳总分较高(平均值 = 100.71,满分为 200 分)。在疲劳维度中,精力不足、身体不适和体力消耗三个维度的得分最高,分别为 27.28 分、26.71 分和 25.71 分。背部(54.7%)、颈部(50.7%)和肩部(49.3%)的 MSD 患病率最高。根据 ISO 7243 标准,温室工人的平均 WBGT 超过了大多数任务的允许水平。职业疲劳与 MSDs 和 WBGT 之间存在明显的统计学关系:鉴于报告的疲劳得分相对较高及其与 MSDs 和热应力之间的关系,建议进一步开展更多的应用研究,以调查减轻温室中这一职业群体的热应力和人体工学风险因素的方法。
