Very few studies have analyzed the determinants of diseases related to air pollution in West Africa. Here we examine healthcare utilization for diseases associated with exposure to air pollution.

Undertaken over six waves from June 2016 to February 2019, this cross-sectional study involved three primary health centers in an air pollution hotspot in Cotonou, the largest city and economic capital of Benin. Healthcare utilization data were collected with a validated standardized questionnaire. In all, 7609 patients were surveyed. SPSS software v.20.0.0 was used to run multivariate logistic regressions to identify factors associated with this utilization.

Common factors associated with respiratory, cardiac and dermatological diseases were residence near a high traffic road, age and dry season. Specific associated factors for respiratory diseases were residence in an area far from the hotspot and work in an enclosed, ventilated space; for cardiac diseases, a workplace located in the hotspot and length of residence there of 10–19 years; for dermatological diseases, non-Beninese nationality.

The important proportion of health conditions related to air pollution suggests the need for public health interventions to prevent their future occurrence.
