Assessment of health consequences of fossil fuel energy use in Osun state, Nigeria: burden and implications

AbstractThe use of fossil fuel energy persists in all the continents of the world, especially in Africa. This study examined fossil fuel energy usage and its health implications in residents of Osun State, Nigeria. This was a cross-sectional study done across Osun State Nigeria. The study took place between January and June 2020. 1044 participants were recruited by multi-stage random sampling. Structured questionnaires were used to obtain necessary information from the study participants. The study data shows there were 534 females (51.1%). 601 (57.6%) relied solely on fossil fuel energy compared to 443 (42.4%) who use non-traditional energy sources. The proportion of people whose annual income is less than 56.6 USD (fifty thousand Naira based on the current official exchange rate as of Jan 2024) is far higher among those who use fossil fuel energy (88.0%) compared to those who use modern energy (59.1%). Electricity consumption accessibility was also more likely among those who used modern energy (91.9%) compared to 52.4% of those who use fossil fuel energy for daily energy needs. Reports of ill-health were significantly commoner among those who used fossil fuel than modern energy in the population including asthma illness (15.3% vs. 11.3%), cough (21.1% vs. 16.7%), catarrh (19.3% vs. 10.8%) and difficulty in breathing (9.3% vs. 6.3%) respectively. This study showed that fossil fuel energy use is very prevalent among residents of Osun State, Nigeria. And may be linked with many indices of poverty. It is associated with significant health impacts including respiratory diseases and poor quality of life. There is a need to encourage and implement policies toward effective and efficient energy use among residents in Osun State to reduce the associated long-term health impact.
