Abstract


This study examined the relationship between asthma disease and climatic element in Orlu zone. Reported asthma cases for the period of fifteen years were acquired from Imo State University teaching hospital Orlu, while the weather data of the area were acquired from NIMET for the same period of fifteen years. Data were analyzed using frequency distribution tables and trend analysis in Statistical Package for Social Science (SPSS) and Microsoft Excel, while the distribution of asthma disease across the area was mapped with ArcGIS 10.3 software. It was observed that the total number of asthma cases was higher (215 cases) in the raining season than the dry season which recorded 168 cases. This showed that asthma cases in Orlu zone (from 2005 to 2019) to be more prevalent in the raining season although still very significant in the dry season; with the highest reported asthma cases recorded in the month of May. Average temperature for the period of study indicated a significant increase of approximately 9.30C at the rate of 0.630C per year, rainfall indicated a significant increase of approximately 118.5mm at the rate of 7.9mm per year, while Average Relative Humidity indicated an insignificant decrease of approximately 169.5% at the rate of 11.3 % per year. Furthermore, the regression analysis further revealed enough evidence to accept the Alternate hypothesis affirming that there is significant relationship between asthma disease and climatic elements in Orlu Zone. (Sig. F Change 0.000 at 0.05 significant Level). The study recommended among others that every asthmatic patient should be prepared for asthma attack at all time, but much cautious during cold weather when the incidence is at its peak.
