Municipal solid waste collectors are at risk of experiencing work-related health problems due to the waste they handle and the physical effort they put in. Work-related injuries among domestic waste collectors have been the subject of scant research in developing nations. Therefore, it is necessary to describe work-related injuries in these subpopulation groups.
This study aimed to determine the prevalence and associated factors of work-related injury among municipal solid waste collectors in Hawassa city, Southern Ethiopia.
A cross-sectional study was conducted from January 11 to 30, 2022, with all the registered municipal solid waste collectors (411). Three diploma environmental health professionals assisted in collecting data using a pretested structured interviewer-administered questionnaire; 1 Bachelor of Science environmental health professional served as a supervisor. Statistical Package for the Social Sciences (SPSS) version 20.0 was used to enter, clean, code, and analyze the data. Associations between independent and dependent variables were assessed, and the strength of the associations was presented by using Adjusted Odds Ratio (AOR) and 95% confidence intervals (CI). According to the bivariable analysis, all independent variables associated with a -value <.25 were entered into a multivariable logistic regression model. Variables in the multivariable regression analysis were considered significant if their -value was less than 0.05.
In this study, the prevalence of work-related injuries within the last 30 days was 12.9% (95% CI: 9.5, 16.3), while the prevalence over the last 12 months was 59.4% (95% CI: 54.7, 64.0). After adjusting for possible confounding factors, age 18 to 24 years [AOR = 1.72;95% CI: (1.07, 2.76)], lack of personal protective equipment (PPE) utilization [AOR = 2.30; 95% CI: (1.44, 3.68)], chewing khat (yes) [AOR = 2.32;95% CI: (1.32, 4.08)], drinking alcohol (yes) [AOR = 1.80; 95% CI: (1.003, 3.24)] and job dissatisfaction [AOR = 2.26, 95% CI: (1.44, 3.54)] were shown to be significantly associated with work-related injury.
The prevalence of work-related injuries was high. Age 18 to 24 years, chewing khat, drinking alcohol, lack of PPE utilization, and job dissatisfaction were significantly associated with work-related injury. Based on the findings of this study, we suggest that addressing these risk factors could help to reduce work-related injuries.
城市固体废弃物收集者由于所处理的垃圾以及付出的体力劳动，面临与工作相关的健康问题风险。在发展中国家，家庭垃圾收集者的工伤问题研究较少。因此，有必要描述这些亚人群体中的工伤情况。
本研究旨在确定埃塞俄比亚南部哈瓦萨市城市固体废弃物收集者工伤的患病率及相关因素。
于2022年1月11日至30日进行了一项横断面研究，对象为所有注册的城市固体废弃物收集者（共411人）。三名环境卫生专业文凭持有者使用预先测试的结构化访谈问卷协助收集数据；一名环境卫生专业理学学士担任主管。使用社会科学统计软件包（SPSS）20.0版本录入、清理、编码和分析数据。评估自变量和因变量之间的关联，并使用调整后的优势比（AOR）和95%置信区间（CI）表示关联强度。根据双变量分析，所有P值<0.25的自变量都被纳入多变量逻辑回归模型。如果多变量回归分析中的变量P值小于0.05，则认为具有显著性。
在本研究中，过去30天内工伤的患病率为12.9%（95%CI：9.5，16.3），而过去12个月内的患病率为59.4%（95%CI：54.7，64.0）。在对可能的混杂因素进行调整后，18至24岁[AOR = 1.72；95%CI：（1.07，2.76）]、未使用个人防护装备（PPE）[AOR = 2.30；95%CI：（1.44，3.68）]、咀嚼恰特草（是）[AOR = 2.32；95%CI：（1.32，4.08）]、饮酒（是）[AOR = 1.80；95%CI：（1.003，3.24）]和工作不满意[AOR = 2.26，95%CI：（1.44，3.54）]与工伤显著相关。
工伤患病率较高。18至24岁、咀嚼恰特草、饮酒、未使用个人防护装备和工作不满意与工伤显著相关。基于本研究结果，我们建议解决这些风险因素有助于减少工伤。
