Background: Anemia impairs physical capacity and work performance in all age groups. Inrnchildren, anemia affects cognitive and motor development because of the need for adequaternoxygen carrying capacity during the critical first few years of life when mental and physicalrngrowth are occurring at their fastest. In Ethiopia, Anemia among children aged 6-59 monthsrnchildren categorized as severe public health problem. Regular monitoring of the magnitudernanemia and its predicting factors is helpful for appropriate intervention.rnObjective: To assess the magnitude of anemia and associated factors in children aged 6-59rnmonths at Keranyo health center, Addis Ababa, Ethiopiafrom January 01 to February 30, 2020.rnMethod: A cross sectional health facility based study wasconducted among 427 children aged 6rnto 59 months. Convenient sampling technique was used to include the participants. Pretested andrnstructured questionnaire was used to collect socioeconomic and demographic characteristics ofrnthe family and child. Data on nutritional status and capillary blood sample was collected fromrneach child. Multivariate logistic regression was used to calculate adjusted odds ratios with therncorresponding 95% confidence intervals.P-values less than 0.05 was also used to declarernstatistical significance.rnResult: Of the total 427 children, 210 (49.2%) were males. The overall prevalence of anemiarnamong children aged 6-59 months was 177(41.5%) (95% CI: 36.8% - 45.9%). Of the anemicrnunder-five children, 14(3.3%) had mild, 149(34.9%) moderate and 14(3.3%) had severe anemia.rnChildren whose maternal education is below elementary((AOR=3.82, 95% CI = (1.66, 8.77)),rnchildren who had fever in the last 2 weeks (AOR=2.13; 95% CI: (1.33, 3.42)), who consumed tearn(AOR=2.17; 95% CI: (1.20, 3.93)) and with mothers who was not supplemented with iron duringrntheir last pregnancy (AOR=3.02; 95% CI: (1.40-6.55)) were more likely to become anemic.rnConclusion: This study confirmed thatthemagnitude of anemia in children aged 6-59 months inrnKeranyo health centeris in the severe public health category. Educational and occupational statusrnof the mother, child history of fever in the last two weeks, child tea consumption and maternalrniron supplementation during pregnancy were factors associated with anemia in those children (659rnrnmonths).Therefore, strengthening awareness and bringingbehavioural change in order tornincrease the knowledge of reproductive women about anemia is warranted.
