Manual Material Handling (MMH) is a type of heavy work that causes a wide variety of musculoskeletal disorders (MSDs). Porters constitute a poor socioeconomic group of workers who are faced with these risk factors. This study focuses on porters who push and pull loads of goods on handcarts inside and outside the Tehran Grand Bazaar.
This study was conducted to investigate the prevalence of MSDs in porters of the Tehran Grand Bazaar.
Based on official registries, more than 5000 porters work in the Tehran Grand Bazaar. In total, 398 porters were selected using the simple random sampling method. The prevalence of MSDs was assessed using the Standardized Nordic Questionnaire for the Analysis of Musculoskeletal Symptoms. The tasks of the porters were analyzed during walk-through surveys in the Tehran Grand Bazaar.
The prevalence of MSDs in at least one body part was 53.8% in the last 12 months and 45.2% in the last 7 days. The most prevalent symptoms in the last 12 months were low-back pain (29.6%) and knee pain (19.6%). Symptoms were associated with age, height, weight, waist circumference, work duration, number of children, and manually handling goods heavier than 20 kg.
The prevalence of MSDs is high in the porters of the Tehran Grand Bazaar, likely due to heavy MMH.
手动搬运（MMH）是一种重体力工作，会导致多种肌肉骨骼疾病（MSD）。搬运工是社会经济地位较低的工人群体，他们面临着这些风险因素。本研究关注的是在德黑兰大巴扎内外推拉货物手推车的搬运工。
本研究旨在调查德黑兰大巴扎搬运工的肌肉骨骼疾病患病率。
根据官方登记，有 5000 多名搬运工在德黑兰大巴扎工作。总共使用简单随机抽样法选择了 398 名搬运工。使用肌肉骨骼症状分析的标准化北欧问卷评估肌肉骨骼疾病的患病率。在德黑兰大巴扎的步行调查中分析了搬运工的任务。
在过去 12 个月中，至少有一个身体部位出现肌肉骨骼疾病的患病率为 53.8%，在过去 7 天中为 45.2%。在过去 12 个月中最常见的症状是下腰痛（29.6%）和膝痛（19.6%）。症状与年龄、身高、体重、腰围、工作时间、子女数量以及手动搬运超过 20 公斤的货物有关。
德黑兰大巴扎搬运工的肌肉骨骼疾病患病率较高，可能是由于繁重的手动搬运工作所致。
