Background: Nutrition is central pillar of human life and its request differ with respect to age, gender and during physiological changes such as complimentary feeding and child age. Ethiopia has a high prevalence of Acute and Chronic Malnutrition, with almost half of Ethiopian children chronically malnourished and one-in-ten children wasted. About 47% of children under-five are stunted, 11% are wasted and 38% are underweight. Acute malnutrition also known as wasting, it is characterized by a rapid deterioration in nutritional status over a short period. For children, it can be measured using the weight-for-height nutritional index or mid-upper arm circumference. There are different levels of severity of acute malnutrition: moderate acute malnutrition (MAM) and severe acute malnutrition (SAM). The recommended a revision of cut-off points to determine wasting are the following: SAM: MUAC < 110 mm for Severe Acute Malnutrition (SAM), Moderate Acute Malnutrition (MAM): MUAC > 115 and < 125 mm Cut-Off Value Normal ?125 mm.

A cross- sectional descriptive survey and measurements of MUAC was used to investigate Prevalence of wasting and Its Associated Factors among Children 6-59 Months of Age in Guto Gida District, Oromia, Ethiopia. Multistage random sampling technique was used and 359 children between 6-59 months aged were selected from 398 enrolled children to the study. The quantitative data were analyzed using SPSS for windows version (17.0) and EPI-6. Both bivairate and multiple logistic regressions were run to assess factors that were associated with the dependent variable at p< 0.05 and to control the confounders.
