“…12,36 A study in Turkey reported a lower prevalence of phlegm (20.46%) 42 than our finding, which might be explained by the population and cultural differences. However, the prevalence of phlegm in this study was lower than studies in Iran (38% and 38.1%), 40,41 Tehran (41.6%) 37 and Gujarat (45.1%). 39 The difference might be because of sample size, socioeconomic status and exposure level.…”

Introduction: Occupational respiratory symptoms are manifestations of respiratory diseases because of exposure to dust or chemicals such as asbestos, silicon and aluminium in the workplace like cement factory, tannery, textile and/or street sweeping, all of which affect the health condition and productivity. In Ethiopia, several primary studies were conducted regarding the magnitude of occupational respiratory symptoms with the prevalence of 68.89% in street sweepers and associated factors with inconsistent results. This meta-analysis aimed to pool the prevalence of respiratory symptoms and their associated factors among Ethiopian adults working in different workplaces. Methods: PubMed, African Journals Online, Google Scholar, Cochrane Library and Direct Google were systematically searched to identify primary studies. Two authors performed data abstraction and quality assessment for each included study independently. Cochran’s Q-statistic and I2 (I-squared) statistic were used to check heterogeneity. DerSimonian and Laird random-effects models were used to estimate the pooled prevalence and associated factors of respiratory symptoms. Publication bias was checked by funnel plot and Egger’s test, and also sensitivity analyses were performed. Results: Ten primary studies with 3441 study participants were included for the narrative synthesis and meta-analysis of the pooled prevalence of occupational respiratory symptoms. The pooled prevalence of overall occupational respiratory symptom was 54.58% (95% CI: 45.37–63.79). Dry cough was the most encountered respiratory symptom [34.93, 95% CI: 29.52–40.35], followed by breathlessness [28.67%, 95% CI: 20.13–37.22]. Work experience of over 5 years [OR = 2.24, 95% CI: 1.21–4.16] and educational level of Grade 8 and lower [OR = 1.28, 95% CI: 1.06–1.55] were significantly associated with occupational respiratory symptoms. Conclusion: In this review, the pooled prevalence of occupational respiratory symptoms was high. The findings of this study dictate the need for the implementation of workplace safety measures. Special attention is required to employees with lower educational level and longer duration of work experience. Prospero registration: CRD42020176826

“…Also, in a recent study using the American Thoracic Society respiratory questionnaire, involving 86 street sweepers and 80 office workers (matched by age and smoking habits), all respiratory symptoms, including cough, phlegm, cough with phlegm, dyspnea and wheezing, were more prevalent in street sweepers than in office workers (p < 0.001). It could be shown that the chances of experiencing cough, phlegm, dyspnea and wheezing were 21.9 (95% CI: 9.8-49), 48.6 (95% CI: 6.4-367), 4.3 (95% CI: 2.2-8.3), and 15.8 (95% CI: 6.9-8.3) times higher, respectively, in the exposed group than in the unexposed group [21]. Eleven publications showed that street sweepers reported more frequent respiratory complaints compared to the corresponding control group (Table 2).…”

Street cleaning is an integral part of the solid waste management system. There are different ways to achieve clean streets depending on the availability of equipment, the type and magnitude of dirt, the surface conditions encountered or traffic conditions. In general, hand sweeping by an individual worker or a group, hose flushing, or machine sweeping or flushing are applied. In order to obtain information about the occurrence and relevance of occupational health hazards of street cleaners, the current international literature, as well as corresponding German regulations, were reviewed and evaluated. Street cleaning includes a variety of health hazards for employees. These can be subdivided into effects of occupational tasks and effects of working conditions such as weather or road traffic. The hazards result from physical, chemical and biological exposures, but may also be due to physiological and psychological burden or inadequate safety aspects. The most commonly reported work-related complaints are musculoskeletal and respiratory disorders, cuts, slips, and road traffic accidents. In developing countries, street cleaners seem to be still heavily exposed to dust and, in most cases, no suitable protective measures are available. Especially in industrialized countries there exist a number of standards and recommendations for waste workers that aim to reduce their occupational health impacts.

“…In particular, cough was the most common complaint of the sweepers (81%) compared to the controls (16.3%). In addition, the mean FVC and PEF25 -75 were significantly lower in the exposed group compared to the control group (13).…”

Background: In Iran, most of the cleaning processes are performed manually in urban areas. Sweepers are exposed to respiratory pollutants, infectious substances, and other hazardous substances such as chemicals, animal feces, and sharp objects during improper disposal of waste. Respiratory pollutants in these occupations can cause inflammation and damage to the respiratory system. Moreover, prolonged exposure to respiratory pollutants in the workplace can reduce lung function and cause numerous health problems. Objectives: This study aimed to examine the effect of workplace exposures of municipal solid waste collectors on the reduction of the pulmonary function level. Methods: This retrospective cohort study was performed on 198 municipal solid waste collectors aged 18 to 55 years who were employed in this profession for at least two years. The sampling method was census, and demographic data were extracted from occupational examination records. Results: Examining the relationship between pulmonary function decline and the studied variables showed a significant relationship between smoking and reduction of FVC, FEV1, and FEF25 -75. However, no significant relationship was observed between dust exposure and pulmonary function decline. Conclusions: No significant relationship was observed between pulmonary function loss and occupational dust exposure in municipal solid waste collectors. This means that the occupational exposure of these individuals was not severe enough to cause pulmonary function loss.
