“…The prevalence of allergic rhinitis in this study is high compared to that reported in Bogota (26.1%) in traffic police [26] and in a study done in Benin [27] among residents near busy roads with a prevalence of allergic rhinitis of 35.7%. Studies have shown higher prevalence of allergic rhinitis than those found in our study in workers with high exposure to outdoor air pollution in Nigeria (48.9%) [28] and Italy (48.5%) [29]. Consistent with previous studies, the prevalence of allergic rhinitis decreases with age [6] [30].…”

Introduction: The work environment is one of the main causes of allergic rhinitis. The majority of vendors in Dakar work in places close to roads that are very frequented by vehicles, exposing them to increased air pollution. The study determined the prevalence of allergic rhinitis and its associated risk factors in these vendors. Methods: This was a cross-sectional survey based on a structured questionnaire, conducted among vendors in the neighborhoods of HLM, Medina and Petersen in Dakar, Senegal. A total of 200 vendors were interviewed. Symptoms of allergic rhinitis were defined as the simultaneous presence of rhinorrhea, nasal congestion and sneezing in the absence of respiratory infection. A logistic regression analysis was performed to determine the relationship between socio-demographic characteristics, occupational factors, and allergic rhinitis. Results: Results of the study show a prevalence of 43% of allergic rhinitis among vendors. Multivariate analysis showed that the independent factors associated with allergic rhinitis in these vendors were age

“…Vendors who had a long daily working time, had a higher prevalence of allergic rhinitis. This is due to the duration of exposure to air pollutants as shown by the study by Obaseki et al, 2014 [28]. Some studies showed that BMI is associated with the prevalence of allergic rhinitis.…”

“…In fact, the prevalence of diagnosed allergy in traffic warders (almost 50%) was statistically higher than in non-exposed office employers. Before us, Proietti et al found no statistically significant association between occupational exposure and diagnosis of allergic diseases [67], while Gao et al highlighted only a greater risk of allergic-related respiratory symptoms [68]. Regarding the latter, our analysis found no difference in pulmonary function between the exposed and control groups.…”

(1) Background: Particulate matter increases the risk of respiratory, allergic and oncological diseases in both exposed workers and the general population due to its toxic compounds (e.g., PAHs, gases, heavy metals, microorganisms). The aim of this review is to show the results obtained by our department regarding air pollution's contributions to health damage in both occupationally and non-occupationally exposed people. (2) Methods: This review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching articles on PubMed, using eligibility criteria, extracting data independently from reports to reduce bias and considering the accuracy of the statistical analyses. (3) Results: Of fifteen papers, only three respected the abovementioned criteria. A total of 453 cases (174 occupationally exposed and 279 non-occupationally exposed individuals) were included in the review. Qualitative analysis showed that among workers, occupational exposure to air pollution increased the risk of allergic and pulmonary diseases, whereas environmental exposure to PM increased heavy metal intake, the last of which was characterized by well-known carcinogenic effects. 4) Conclusion: The use of personal protective equipment, a meticulous health surveillance program and specific environmental protection policies are needed to protect public health from damages due to air pollution.

“…However, most studies of workers exposed to traffic air pollution have been made in traffic police because of their high exposure to this pollution. In the traffic police in Nigeria, a high prevalence of respiratory symptoms was also found [14]. A predominance of respiratory symptoms has been found in bus drivers working in the HLM neighborhood.…”

Introduction: Road traffic exposes bus drivers to the detrimental effects of air pollutants on respiratory health. This study determined the frequency of chronic respiratory illnesses and its related factors among bus drivers in Dakar, Senegal. Methods: This study had a cross-sectional design conducted in a total of 178 bus drivers in Dakar, Senegal. A questionnaire was used to inquire about socio-economic characteristics, occupational factors and respiratory symptoms of bus drivers. Lung function tests were used to determine the presence of asthma and Chronic Obstructive Pulmonary Disease (COPD). The relationship between our variables of interest and respiratory diseases was determined by logistic regression analysis. Results: The results of the study show that 57.9% of bus drivers had a chronic cough, and 65.7% had recurrent cold. Lung function tests showed that 38.8% of bus drivers had asthma and 30.3% COPD. Multivariate analysis found that recurrent cold increased the risk of asthma (OR = 6.3, 95% CI: 1.12 -35.79) and COPD (OR = 7.7, 95% CI: 1.14 -52.8). The respiratory health status of bus drivers depended on the work area (OR = 3.2, 95% CI: 1.13 -9.31). Conclusion: The respiratory symptoms and illnesses observed among bus drivers are associated with their exposure to air pollutants from road traffic.
