Background: An inadequate nutrient intake is a challenge among many 6-23 months of children in most developing countries. But, little study was conducted in Ethiopia regarding to nutrient intake inadequacy among in 6-23 months of children. Objective: To assess nutrient intake inadequacy and its associated factors among 6-23 months of children in Bahir Dar city, North West Ethiopia,2021. Methods: Community-based cross-sectional study was conducted from February 15/2021 to March 05/2021 in Bahir Dar city. Simple random sampling technique was used to recruit a total of four hundred twenty respondents. Data were collected by interviewer administered semi structured questionnaire and a single multiphasic 24-hour dietary recall was used to assess dietary assessment. The nutrient intakes were assessed by Nutrient Adequacy Ratio (NAR) and Mean Adequacy Ratio (MAR). Data entry and analysis were carried out using EpiData and SPSS respectively Multivariable logistic regression was performed to identify determinants of overall micronutrient intake inadequacy at a p-value of less than 0.05. Result: The overall prevalence of nutrient intake inadequacy across 14 nutrients was 47.5%. (95%CI: 42.4%-52.2%) The inadequate intake of vitamin A was 97.5%. Children from informal educated mothers were 4.67 times more likely to have overall nutrient intake inadequacy as compared with those who had formal educated mother [AOR=4.67, 95%CI (2.45-8.88)]. Children who had ≤2 times meals/day were 2.83 times more likely to had nutrient intake inadequacy than who have more than 4 times a day [AOR=2.83, 95%CI (1.13, 7.07)]. Respondents who had poor nutritional knowledge were 6.18 times more likely to had nutrient intake inadequacy to the child than those who had good nutritional knowledge, [AOR=6.18, CI, (3.52, 10.84)] .Children whose mothers’ age 19 -29 years were 1.7 times more likely to had nutrient intake inadequacy than those mothers’ age above 29 years [AOR=1.76, 95%CI (1.11, 2.79)]. Conclusions: Overall, the nutrient intake in 6-23 months ‘of children was lower than the recommended levels. Therefore, educating the child mother and family about appropriate dietary intake is essential. Nutritional knowledge, maternal education, maternal age, meal frequency were the significant factors of overall nutrient intake inadequacy. Key words: inadequate nutrient, 6-23 months ‘of child, Bahir Dar city, Ethiopia.
