Assessment of Blood Pressure Level of Inhabitants of Ibadan and Its Metropolis, Using Log-Normal Model

Several papers written by many medical researchers have disclosed that hypertension and its related complications are major health problems not only in Nigeria but in Africa at a large. Thus, this paper attempted at assessing the expected blood pressure level of the hypertensive patients inhabited in Ibadan city and its environments. Precisely, the diastolic blood pressures of 30 randomly selected patients visited University College Hospital, Ibadan between 23/07/2008 and 12/08/2008 for medical check-up are the data used for the assessment, and the evaluation was done using 2parameter lognormal model. It is deduced from the analysis that the model is deemed fit for the data used following the confirmatory kolmogorov Smirnov one sample test carried out. Also the result of the test disclosed that the expected diastolic blood pressure of patients visited the hospital between the period under study is 91.525 mmhq with a standard deviation of 16.8154 mmhq. Finally, we observed that the expected diastolic blood pressure obtained is greater than that of World Health Organization standard (90mmhq), meaning that the patients under study are hypertensive patients.
