The main objective of this research project is to assess the causes and effects of anaemia among pregnant women attending specialist hospital Yola, Adamawa State. A population of sample size of 100 women was selected at random from the population of the study without bias. The finding of this study revealed in the age group 15-30; 24% and 19% agrees and strongly agrees respectively that anemia is caused by iron or other nutrient deficient. In the age group 31-avove; 12% and 21% agrees and strongly agrees respectively that anemia is caused by iron or other nutrient deficient. The age group 15-30; 15% and 34% agrees and strongly agrees respectively that anemia can caused death of the offspring. In the age group 31-avove; 19% and 18% agrees and strongly agrees respectively that anemia can result to the death of the offspring. the age group 15-30; 15% and 25% agrees and strongly agrees respectively that anemia can caused death of the mothers during labour. The age group 31-above; 10% and 23% agrees and strongly agrees respectively that anemia can result to the death of the mother during labour. The age group 15-30; 28% and 13% agrees and strongly agrees respectively that anemia can lead to reduce body mass. In the age group 31-avove; 27% and 14% agrees and strongly agrees respectively that anemia can lead to reduce body mass. However the result of the Chi-square test shows that the p-value is greater than 0.05 in all the responses of the participant in relation to both their age and Education status, this implies there was no significant difference in all the responses. It is recommended that all pregnant women should ensure constant visitation of antennal as to continue getting knowledge on issues related to pregnancy.
