Fifty cord
blood samples from the umbilical cord of neonates were used for the evaluation
of parasitaemia. The samples showed positive smear for malaria with a
prevalence of 60.0%.
The result
from table 1 shows that women within the age group of 30-39 has the highest
level of parasitaemia (36%). Chi-square analysis of the distribution of
parasitaemia on cord blood in relation to trimester and age show that parasitaemia
is dependent on both trimester (p>0.05) age group (p>0.05).
This
means that the degree of parasitic infection, among other factors, is affected by
both trimester and age group of the individual.

The
table above showed that the overall prevalence of parasitaemia is 60% (30/50). Also
the highest prevalence is seen in women of age group 30-39.

The table
above indicates that the
calculated degree of freedom is 2, the
level of significance used is 0.05 , the
calculated chi square with the degree of freedom as 2 and
probability level at 0.05 is
0.126 while the critical value of
x2 (x2tab) is P>O.05
The null hypothesis is rejected and this
means that the distribution of parasite on pregnant women is dependent on
trimester.
