B. 5363, Ado-Ekiti (Nigeria) Department of Science Laboratory Technology, Moshood Abiola Polytechnic, PMB 2210, Ojere, Abeokuta (Nigeria) This retrospective study was based on the pattern of mortality as recorded for in-patients in the male and female wards of the Ekiti State Specialist Hospital, Ado Ekiti, Ekiti State, Nigeria between 1997 – 2001. The population involved was 370 distributed as 288 (77.8%) males and 82 (22.2%) females. Total number of months was 81 distributed as 59 (72.8%) months for males and 22 (27.2%) months for females. The fatality diseases for males ran thus: tuberculosis 41 (14.2%) > cardiovascular arrest 28 (9.7%)> tetanus 24(8.3%)> congective cardiac failure 19 (6.6%) > meningitis/typhoid 18(6.3%) and for females: cardiovascular arrest 16 (19.5%) > tuberculosis 13 (15.9%) > diabetes melitus 7 (8.5%)> congective cardiac failure 6 (7.3%) and malaria / meningitis 4 (4.9%). The age bracket analysed was 11-100years. Diseases causing mortality among the productive ages of men were tuberculosis (11-70years), lung pneumonia (11-70y), congective cardiac failure (11-70y), meningitis (11-60y), diabetes melitus (11-70y), acquired immune deficiency syndrome (32-45y); for females: tuberculosis (11-70y), diabetes melitus (11-60y), cardioascular arrest (31-80y), malaria fever (11-40y) and meningitis (11-30y). https://www.biotech-asia.org/vol4no1/adults-mortality-pattern-as-seen-in-ado-ekiti-specialist-hospital-ekiti-state-nigeria-1997-2001/ Restrospective study; fatality diseases; productive ages
