Distribution of ABO and Rh-D blood groups in the Benin area of Niger-Delta: Implication for regional blood transfusion

Abstract

ABO and Rhesus (Rh) blood group antigens are hereditary characters and are useful in population genetic studies, in resolving medico-legal issues and more importantly in compatibility test in blood transfusion practice. Data on frequency distribution of ABO and Rh-D in Niger-Delta region of Nigeria are not available; hence we made an attempt to retrospectively analyze the records on the blood donors, transfusion recipients and patients attending antenatal care or some other medical interventions. Over a twenty-year period between 1986 and 2005, a total of 160,431 blood samples were grouped for ABO and Rh-D at the blood bank of the University of Benin Teaching Hospital, Benin City, Nigeria. Blood group distribution among these samples showed phenotypes A, B, AB and O as 23.72%, 20.09%, 2.97% and 53.22%, respectively. The Rh-D negative phenotype was found among 6.01% of the samples tested.

Plasmodium Malaria and ABO Blood Group among Blood Donors in Yenegoa, Bayelsa State, Nigeria

“…The prevailing blood group among the studied population showed that blood group O+ had the highest prevalence with 53.3%.This finding agrees with Enosolease and Bazuaye who reported 53.2% in Benin area of Niger-Delta, Abah and Joe-Cliff who reported that people in Blood group O were more than those of the other blood groups among blood donors in Port Harcourt and Odokuma et al who also reported blood group O as the most common among students of the Abraka campus of Delta State University in Nigeria [21,36,37]. This supports the universal knowledge that blood group O is the commonest of all the blood groups.…”

Blood Group and Rhesus Factor Pattern among Indigenes of FCT, Abuja, Nigeria

“…Blood group A, B, AB, and O had the 21.6%, 26.2%, 4.9% and 47.2% respectively. The result is similar to the result obtained by [5] [6].…”

“…The results of this study showed that blood group O was the highest with a percentage frequency of 47.2% followed by blood group B with a percentage frequency of 26.2%, blood group A as 21.6% and AB as 4.9% which is in correlation with the study made by [9], but blood group A and B was found with variation in the frequency of distribution when compare with the study made in Nigeria as a whole by [6]. This could be as a result of variation in sample size.…”

“…So having adequate knowledge about one's blood group can be very informative and will help improve the health status of people. Though studies have been carried out and published on several ethnic groups in Nigeria like Ogbomosho, Oyo State [5], Benin, Niger-Delta region [6], some other ethnic groups still have their statistics not known and this ignorance has led to high rates of mortality. It is to this effect that this study is being carried out among the indigenes of FCT, Abuja, Nigeria to determine if tribe and ethnicity was a factor that affects variations in blood groups since there are no published data regarding the Blood group and Rhesus factor among the indigenes of FCT, Abuja, Nigeria.…”
