Anaemia is one of the most common outcomes of malaria and STH infection. The prevalence of anaemia was 53.9%; with minimum, maximum and mean Hematocrit values of 18%, 48% and 32.7%, respectively. This result was almost similar to that of anaemia prevalence in Bushulo health centers, Ethiopia 51.9%  but slightly higher than the anaemia prevalence previously reported from Jimma health center 41.9% , Asendabo health center 23% , and Peru 47.31% . Our findings are close to the figures reported by UNO  and a small variation from other studies may be due to the selection of study population.
From the total of 209 anaemic women; 115 (55%), 88(42.1%), 6 (2.9%) were with mild, moderate and severe anaemia, respectively. This finding is higher than the study conducted on pregnant women in Malaysia, which reported 45%, 9.8%, and 1.85% with mild, moderate and severe anaemia, respectively .
Our findings indicated that pregnant women from rural residences, not using ITN during the study period, those who were Plasmodium infected and those with STH infection were highly likely to be anaemic compared to those from urban residences, using ITN, free of Plasmodium and STH infection.
In the current study those pregnant women who had a habit of walking bare foot had high anaemia prevalence (57.8%). Walking barefoot may predispose to hookworm infection and consequetly may result in iron deficiency anaemia especially in pregnant women . Hookworm infection rate was also associated with anaemia in which those pregnant women infected with hookworm have a 2.4 times higher risk of developing anaemia, as 68.4% of the pregnant women infected with hookworm were anaemic. This finding is similar to the findings of other similar studies [10, 20]. There was a significant correlation between increasing hookworm parasite load, A.lumbricoides and T. trichiura and decreasing hematocrit values. This shows that as the helminth parasitic load increased the hematocrit level decreased; as a result the risk of developing anaemia increased. This result was comparable to a study from Peru, where there was a significant correlation between increasing hookworm egg counts and decreasing haemoglobin levels . In this study prevalence of anaemia in pregnant women was higher in malaria and STH infected pregnant women, which is in agreement with the findings of many studies [5, 10, 20, 21].
There are, of course, limitations in this study. Even though this study tried to address some important factors, other factors, such as other nutritional deficiencies (including folate, vitamin B12 and vitamin A), acute and chronic inflammation, and inherited or acquired disorders that affect haemoglobin synthesis, red blood cell production or red blood cell survival, which can all cause anaemia, were not addressed. In this study anaemia in pregnancy was also not standardized for residential elevation above sea level (altitude). In addition, the study was not out of the limitations of cross sectional study like identifying the cause and effect relationship.
