Mortality Experience Of A Cohort Of Academic Staff Retirees Of University A Case Study Of University Of Ibadan Nigeria

Abstract The study arose out of the need to know the distribution of experience of mortality and survival pattern of University academic staff retirees. This is a follow up study of a cohort of retired university academic staff in retrospective in a well based record assessment. From total population of 302 of pensionable 60 to 65 years of age of service and 35 years in service as at year 2012 of retired academic staff retirees surveyed 109 were randomly selected during the study dates January 1977 to December 2012. Simple descriptive frequency and the Life Table analysis were identified as the most suitable approach to analyze the demographic characteristics and pattern of survival this provides estimates of probabilities of surviving a given number of years after retirement. Since life table is non-parametric procedure for estimating life expectancy at different points and does not produce a measure of precision. We exploit the distribution of the survival and hazard functions to give a measure precision of life expectancy. The result shows that there is no significant difference in the survival probability of male and female Using Log rank test with p value of 0.72 there is significant different between mortality rate of those who retired early as a result of length of service and those who retired late as a result of age limit with p value of 0.02 there is no significant difference in the survival probability for male and female and their duration of service with Log rank test probability of 0.93 and Post Retirement Occupation PRO and the survival time of academic retirees are significant different with p value of 0.013. The median residual life time for male is 9.21 while for female is 8.48 years.
