Geographical regions may have an influence on asthma exacerbation. No conclusive study has been conducted to fully support or dissipate this assertion. We sought to use a data-driven approach to investigate the possible effect of geographical location on asthma. This study was based on data collected by the Ministry of Health over a 6-year period from 2010 to 2015 and presented in their annual reports. Prevalence rates for 11 regions were computed using the analysis of variance and regression models to determine the proximal nature of the region as a risk factor for asthma. Our results show a statistically significant difference in prevalence rates of asthma among the 11 regions. The asthma prevalence rate among the male population was 18% (OR = 1.18, p =.011) more than for the female population. There was a positive marginal increase in the asthma prevalence over the period. Further, five groups were derived based on asthma prevalence rates and trends. The region has proximal risk factor and significantly associated with asthma prevalence over the period. We recommend the creation of a control mechanism that targets regions with higher prevalence and increasing trends.
