Quarry workers are commonly afflicted with musculoskeletal disorders (MSDs). This health problem has been recognized as a significant threat to the quarry workers' safety but is rarely reported, particularly in Nigeria. Therefore, this study aimed to assess the prevalence of MSDs and their associated factors among quarry workers.
A cross-sectional study was conducted, and data were collected using a self-administered Standard Nordic Musculoskeletal Questionnaire. A total of 266 participants were selected through systematic random sampling method among male and female quarry workers in Ebonyi State, Nigeria. The data were analysed using SPSS version 26, and descriptive statistics were used to determine the prevalence and types of MSDs. Simple and multiple logistic regressions were used to identify the factors associated with MSDs.
The results revealed that majority of the respondents (89.8%) had MSDs, with the most common types being lower back pain (83.1%) and elbow pain (45.9%). Based on multiple logistic regression modelling, BMI (Adjusted OR 0.17, 95% CI 0.06,0.55, p = 0.003), age (Adjusted OR 1.14, 95% CI 1.07, 1.23, p < 0.001), work experience (Adjusted OR 2.08, CI 1.00, 4.30, p = 0.049), Vibration exposure (Adjusted OR 0.45, CI 0.27, 0.74, P = 0.002), working hour (Adjusted OR 6.84, CI 0.84, 53.4, p = 0.007) and break time (Adjusted OR 0.95, 95% CI 0.91,0.98, p = 0.006) were significantly associated with MSDs.
MSDs are prevalent among the quarry workers in Ebonyi State, Nigeria. Thus, there is an urgent need to increase the workers' and employers' awareness of appropriate ergonomic and personal measures needed to improve the workers' safety and well-being.
采石场工人普遍患有肌肉骨骼疾病（MSDs）。这一健康问题已被视为对采石场工人安全的重大威胁，但很少有报道，尤其是在尼日利亚。因此，本研究旨在评估采石场工人中肌肉骨骼疾病的患病率及其相关因素。
进行了一项横断面研究，使用自行填写的标准北欧肌肉骨骼问卷收集数据。通过系统随机抽样方法，在尼日利亚埃邦伊州的男女采石场工人中总共选取了266名参与者。使用SPSS 26版对数据进行分析，描述性统计用于确定肌肉骨骼疾病的患病率和类型。简单和多元逻辑回归用于识别与肌肉骨骼疾病相关的因素。
结果显示，大多数受访者（89.8%）患有肌肉骨骼疾病，最常见的类型是下背痛（83.1%）和肘部疼痛（45.9%）。基于多元逻辑回归模型，体重指数（调整后的比值比为0.17，95%置信区间为0.06,0.55，p = 0.003）、年龄（调整后的比值比为1.14，95%置信区间为1.07,1.23，p < 0.001）、工作经验（调整后的比值比为2.08，置信区间为1.00,4.30，p = 0.049）、振动暴露（调整后的比值比为0.45，置信区间为0.27,0.74，P = 0.002）、工作时长（调整后的比值比为6.84，置信区间为0.84,53.4，p = 0.007）和休息时间（调整后的比值比为0.95，95%置信区间为0.91,0.98，p = 0.006）与肌肉骨骼疾病显著相关。
在尼日利亚埃邦伊州的采石场工人中，肌肉骨骼疾病很普遍。因此，迫切需要提高工人和雇主对改善工人安全和福祉所需的适当人体工程学和个人措施的认识。
