||Objective: Air pollution is becoming one of the public concerns requiring
urgent feasible response per local context. Defining accurately the level of
exposure of outdoor air pollution effect on health of venders working along
main roads and roundabouts with high traffic is important. This study was
conducted to assess respiratory health risks on venders associated with different geographical positions in Cotonou. Methods: A cross-sectional study
was conducted along the main road with high traffic including three roundabouts in Cotonou. The 194 study participants from all shops, one respondent per shop, were given a unique GPS data associated to indicate the
shop’s geographical position. The study employed validated questionnaire on
respiratory symptoms. Results: Study participants had mean age of 36.26
(±11.65) years with sex ratio of (M/F) 1.8. Majority (72.7%) of study participates reported to have at least one respiratory symptom and 69% of them
were working in non-ventilated rooms. The proportion of having at least one
respiratory symptom was significantly different (p < 0.001) between the subpopulations at roundabouts (96.15%) and apart from the roundabouts (64.08%).
The most reported symptoms were cough (47.94%) and itchy nose (42.27%).
The risk of cough (OR = 5.15; 95% CI = [2.21 - 12.04]; p < 0.001) and itchy
nose symptoms (OR = 3.44; 95% CI = [1.55 - 7.63]; p = 0.002) were higher in
individuals working at the roundabouts compared to those working along the
main road. Conclusion: Working in roundabout is associated with more respiratory symptoms than working in shops along main road. Air pollution mitigation efforts should focus in such settings, taking into account the sub-population of workers in resource limited countries.
