Risk factors for anemia among pregnant women attending antenatal clinic at Jimma University Hospital, southwest Ethiopia

OBJECTIVE: to determine anemia and its risk factors among pregnant women METHODS: A cross-sectional analytic study was carried out among pregnant women who came for antenatal care follow up for the first time to Jimma University hospital, Jimma town, southwestern Ethiopia from May-June 2005. RESULTS: A total of 168 pregnant women who came for their first antenatal care visit to Jimma University hospital were enrolled in the study. A structured and interviewer administered questionnaire was used to collect data on the socio-demographic variables, dietary habit and other gynecologic and obstetric history. Dietary data were collected using food frequency questionnaire prepared for assessing nutritional factors for anemia. Sahli hemoglobinometer and a microscope were used for assessing hemoglobin level and stool for hookworm infection, respectively. Data were cleaned, edited and entered in to a computer and analyzed using SPSS for windows, version 11.0. Statistical tests were performed at the level of significance of 5%. The prevalence of anemia was 64/168 (38.2%) and the mean hemoglobin level was 11.3 mg/dl. Anemic cases were 4 times likely to have history of excess menstrual bleeding prior to the index pregnancy 2 times likely to have hook worm infection and 3 times likely not to have shoe wearing habit, 3 times likely to have birth intervals less than 24 moths between the previous pregnancy and index pregnancy (p < 0.05). CONCLUSION: This finding suggests the need for strengthening of interventions related to child spacing and raising awareness about family planning methods. All ANC attendants should be screened for anemia and hookworm infection at first visit and those anemic mothers and infected with hookworm should be treated appropriately. Health education should be given to pregnant mothers on family planning, and the need to gynecologic evaluation before pregnancy and the importance of wearing shoes to decrease hook worm infection and subsequent anemia.
