This is a cross-sectional study on solid waste collectors (SWCs) who are potentially exposed to various occupational health hazards leading to health risks. This study was conducted on 107 solid waste collectors who had completed structured questionnaire interviews between October to December 2019. Data analysis was performed using the STATA software (14.1 version). The majority (93.5%) of SWCs were employed temporarily. Among the total solid waste collectors, 72% of them had occupational health symptoms. This study showed that most SWCs suffered from different types of occupational health symptoms such as musculoskeletal pain and injuries (59.7%), respiratory symptoms (23.4%), head, eyes, and ears symptoms (7.8%), skin symptoms (5.2%), and gastrointestinal symptoms (3.9%). High level of health hazards exposure (ORadj = 5.87, 95%CI = 1.80 – 19.03), shift hours were significantly associated with occupational health problems. Thus, providing occupational safety training and personal protective equipment support in the working environment, including giving knowledge about health hazards and awareness and promoting annual medical checkups, should be considered.
