The retrospective study was carried out in 38,898 healthy adult blood donors of both sexes, recruited mainly from Nairobi area in Kenya. The percentage proportions of blood groups were: group 0-47.4, group A-26.2, group B-22.0 and group AB-4.4. In all the samples, there were 96.1% Rh (D) positive blood donors. Among these were 0.75% subjects with Rh (D) variant antigen Du positive. Rh (D) negative was only 3.9% among the blood donors. There is a real preponderance of the blood group 0 over the blood groups A, B and especially AB as well as Rh (D) positive over Rh (D) negative. The authors found following frequencies of genes: p(A)0.168, q(B)0.142, r(0)0.690, D positive 0.804, D negative 0.196 and compare their own results with the data of other investigators concerning other Kenyan and African populations.

D000017 ABO Blood-Group System The major human blood type system which depends on the presence or absence of two antigens A and B. Type O occurs when neither A nor B is present and AB when both are present. A and B are genetic factors that determine the presence of enzymes for the synthesis of certain glycoproteins mainly in the red cell membrane.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D012204 Rh-Hr Blood-Group System Erythrocyte isoantigens of the Rh (Rhesus) blood group system, the most complex of all human blood groups.

D015994 Incidence The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from PREVALENCE, which refers to all cases in the population at a given time.
