Assessment of respiratory symptoms and associated factors among solid waste collectors in Yeka Sub City, Addis Ababa, Ethiopia

Abstract

Respiratory symptoms are frequently manifested among solid waste collectors. They are suffering from respiratory diseases because of frequent exposure to waste materials containing pathogenic materials and chemicals hazards for human being. Cross-sectional study was carried out to assess prevalence of respiratory symptoms and associated factors among solid waste workers in Yeka sub city, Addis Ababa from March to April, 2016. The sub city has a total of 13 woredas. All woredas had different number of unions organized under small scale enterprises. Thirty eight micro and small enterprise unions from all woredas were selected randomly. Study subjects were taken from selected enterprise consecutively. Observational checklist and structured questionnaire were used to collect data associated with respiratory symptoms. Binary logistic regression was performed to identify the risk factors associated with respiratory symptoms; p-values less than 0.05 were considered statistically significant. The overall prevalence of respiratory symptoms among solid waste collectors in Yeka sub city was 40.7%. Multivariate analysis revealed that respiratory symptoms prevalence was 2 times less likely among individuals use facemask on job (adjusted odd ratio [AOR] 2, 95% confidence interval [CI]: 1.1-4). The prevalence of respiratory symptom was 2.6 times more likely among individuals having sleeping disorder (AOR 2.6, 95% CI: 1.5-4.42). The prevalence of respiratory symptoms was 4.8 times more likely among study subjects who had past illness (AOR 4.8, 95% CI: 3.2-7.22). Respiratory symptoms among solid waste collectors were high. So, individuals participating in collecting solid west should use facemask, while collecting the wastes, municipal should change working hours and individuals who had history of past illness should get health information during enrollment.

Prevalence of Respiratory Symptoms and Risk Factors Among Street Sweepers in Gondar City Northwest, Ethiopia, 2021: A Cross-Sectional Study

“…Street sweepers with a history of respiratory illness are more likely to have respiratory symptoms when compared to those workers without a history of respiratory illness. This finding is consistent with studies conducted in Ethiopia, Addis Ababa, 24 Komblcha, 9 and Malaysia. 13 In this study, another important factor was washing PPE after use, and respiratory symptoms were higher among workers who did not wash their PPE after use when compared to workers who did wash their PPE after use.…”

Magnitude and risk factors of chronic respiratory symptoms among municipal street sweepers in Dessie and Kombolcha City, Northeast, Ethiopia: Cross-sectional study

“…23 However, another study conducted in Ethiopia found that workers who had ⩾5 years of work experience were less likely to have chronic respiratory symptoms compared to those who had <5 years of work experience. 24 The difference may be due to higher monthly income which means those who had longer work experience also had higher monthly income and could afford materials needed for prevention of chronic respiratory symptom.…”

Solid waste motor tricycle operators in Kumasi, Ghana, harbour respiratory pathogens; a public health threat

“…The respiratory symptoms reported by participants include sore throat, cough, difficulty in breathing, persistent cough, chest pain, chronic mucus, and coughing up blood. Several African studies among municipal solid waste workers [ 32 ], door-to-door solid waste collectors and street sweepers [ 33 ] and landfill waste recyclers [ 34 ], waste workers have reported similar symptoms [ 32 – 34 ]. Respiratory symptoms generally indicate respiratory disorders including respiratory infections [ 35 ].…”

“…Solid waste motor tricycle operators who use multiple PPE (more than 1 PPE) had lower odds of being infected with a respiratory pathogen. This may be because the components of the multiple PPE have all been shown to confer some level of protection against respiratory infection [ 32 , 42 ].…”
