Discussion

This
study is significant because the blood group distribution was observed in
Ofuoma community, Delta State. This study revealed that from the samples
analyzed, blood group O was found to be predominant 54 (54%) followed by B: 23
(23%), blood group A: 18 (18%) and blood group AB 5 (5%). This result is
similar to those found in other parts in Nigeria, in Ogbomoso, Kaduna,
Nassarawa, Uyo, Kaduna and Benin. (Akhigbe et
al
, 2009). There are no contrary reports to this within Nigeria.
Internationally blood group O is the most prevalent blood group among the
British, American, Malaysians, and Saudi Arabian (Sivannanthan et al, 2013). The only population where
another blood group other than group O is most prevalent is the Turkish
population where blood A is the most prevalent. (Sari et al, 2009).

The
result of this study further revealed that after  blood group O, the most prevalent blood group
was blood group B, followed by Blood group A. within Nigeria, this is similar
to result from Lagos, Ogbomoso and Kaduna where blood group B were found to be
more prevalent than Blood group A. There are however, contrary report from Uyo,
Akwa Ibom State, and Benin where Blood group A are more in number than Blood
group B (Ekanem, 2013).      
Internationally,
among the British and the American and Saudi Arabians, the percentage frequency
of Blood group A is several times higher than group B, for instance in the
British, Blood group A is present in 42% of the population whereas Blood group
B is present in 8% in Caucasians Blood group A is 41% while Blood group B is 9%
and in Saudi Arabians Blood group A is 33% while Blood group B is 6%. (Giri et al, 2011). In Malaysia however, the
prevalence of Blood group B is higher than Blood group A (Sivananthan et al, 2013)
Rhesus
blood group distribution in this study revealed that Rhesus negative
individuals constituted 6% of the population. This is similar to the study of
Ekanem (2013) in Uyo. This value is in line with the values in other parts of
the country. Rhesus negative constitutes 6.68% in Ogbomoso, 6% in Nasarawa, 6%
Lagos and 5.2% in Kano. (Akhigbe et al, 2009).
The percentage frequency of Rhesus negative is higher in several other
countries. In British Rhesus negative blood group represents 17% of the
population. In Caucasian, it represents 15%, in Saudi Arabian Rhesus negative
constitutes 7.2% and in Kardi, Iraq it is 8.27% (Mohamad, 2010).
In
conclusion, the data from this study revealed that the pattern of ABO and
Rhesus blood group distribution in Ofuoma community Delta State is not very
different from other tribes in Nigeria. This data will help in planning
efficient and safe blood services in the State.
