Abstract

Chronic kidney disease (CKD) is a persistent, devastating, yet neglected, non-communicable disease in developing and emerging countries. National, regional, and international agencies’ communications and reports on non-communicable diseases intentionally or non-intentionally do not feature CKD. The traditional risk factors for CKD, such as hypertension and diabetes, which have received relatively ample attention, do not sufficiently explain the high burden of CKD in these countries.

Ambient air pollution is an emerging significant environmental risk factor for CKD; however, epidemiological data and evidence are lacking for susceptible populations in developing countries. The Niger Delta region of Nigeria is a petrochemical hub known for environmental degradation, including air pollution, and thus, serves as a good case study for investigating the association between air pollution and CKD. This brief is based on the results of a mixed-methods study conducted in four communities situated near an oil and gas refinery in Warri, Nigeria.

Air pollutant concentrations measured in partnership with citizen scientists showed that all except one air pollutant (ozone) exceeded the WHO acceptable limits in all four communities.

The overall prevalence of CKD was high (12.3%) but even higher (18%) in a socially deprived semi-urban community closest to the oil refinery. Hypertension, diabetes, other behavioral risk factors, and exposures associated with CKD were prevalent among the inhabitants of the four communities. However, public environmental health information and education are lacking.

A multifaceted approach is required to mitigate air pollution and the associated health risks in the state. Public inclusion is strongly recommended for the planning and implementation of future interventions. Kidney disease prevention and treatment should be emphasized in health policies and insurance schemes.
