Background In Ethiopia child malnutrition is the major public health problem as 44% and 10% of children under age five years were stunted and wasted respectively. Intake of complimentary food with inadequate energy and micronutrient density coupeled with inappriopriate child feeding practice remain common problem in Ethiopian infant and young child feeding. Despite the fact that there are number of studies indicating high burden of malnutrition in Ethiopia, energy and nutrient adequacy of complementary foods has not been well studied. Therefore this study is designed to assess the dietary adequacy of energy and micronutrients in complementary foods of children aged 6 -23 months. Objective: To determine the adequacy of energy and nutrient intakes among children aged 6-23 months. Methodology A community based cross sectional study was conducted in Southern Ethiopia from February to March 2016. The samples were selected using simple random sampling method. Data on foods and drinks consumed by children aged 6 – 23 months in the previous 24 hours before interview was collected using repeated multiple pass 24-hour dietary recall method. Nutrient content of food was calculated using food processor (version 8.1). Adequecy of nutrient intake and nutrient density were analysed using STATA 12.1. Prevalence of inadequacy was estimated using IMAPP 1.0. Skewness and kurtosis test were made to test normality of continuous variable. Descriptive statistics was carried out to characterize the study population. Result: One hundred ninety (n=190) mother or care givers of children aged 6 -23 months participated. Grain, roots and tubers were consumed by most of the children (94.68%). Vitamin A rich fruits and vegetable consumed by 71 (37.8%) children. Median protein intake exceed recommended intake for children aged 6 – 11 months and was below recommended intake for children aged 11 -23 months. Median intake of energy from complementary food was below the WHO recommendation for children aged 6 -23 months. Median intakes of micronutrients from complementary food were below the WHO recommendation for children aged 6 – 8 months. For children aged 9 – 11 and 12 -23 months median micronutrient intake from complimentary food were below the requirement except for vitamin B2 and vitamin B6. VII Conclusion: Protein intake from complimentary food was adequate for children aged 6 -11 months old. Energy intake from complimentary food was inadequate for children aged 6 -23 months. Micronutrient intake from complimentary food was inadequate except vitamin B2 and vitamin B6 intake were adequate were adequate for children aged 9 - 23 months. Recommendation: In food inscured area such as this, to enure adequate intake of macro and micro nutrient, nutritional counseling complmented with supplementation of may be needed.
