Background: Maternal inadequate nutrition intake has adverse outcomes to the pregnant women as well as the fetus. Inadequate intake of nutrient intake of pregnant women was prevalent. However, there is a limited information regarding nutrient adequacy during pregnancy. Objective: This study aimed to assess nutrient intake inadequacy and its associated factors among pregnant women in Bahir Dar city, Northwest Ethiopia, 2021 Methods: A community-based cross-sectional study was conducted from February 15 to March 05, 2021 among 428 pregnant mothers. Respondents were selected through systemic random sampling. Data was collected using pretested structured interviewer administered questioners. Data were collected by 24-hour dietary recall was used to assess dietary assessment. The collected data from other sections of the questionnaire was coded and entered in to Epi data version 3.1 and exported in to SPSS version 23. ESHA food processor, Ethiopian and world food composition table were used as calculation of nutrient values of selected nutrient. The nutrient intakes were assessed Nutrient adequacy ratio and Mean Adequacy Ratio. Finally, the results were presented in terms of text, frequency tables and graphs. Results: The overall magnitude of nutrient intake inadequacy was found to be 297 (71.7%) [95%CI (67.0, 76.0). Protein, zinc, calorie, fat, vitamin A, C, B1, B2, B3, B6, B12, folate, calcium, carbohydrate and iron mean intakes were 62.5 (±SD 32.8), 7.9(±SD 17), 14(±SD 7.9). 1407.9 (±SD753.6) Kcal, 24.8(±SD21.8), 28.6(±SD 61.2), 36.6(±SD 35.4), 1.1(±SD 0.6), 1.1(±SD 0.7),10.2(±SD 6.6), 0.99(±SD 1), 457 (±SD 273.9), 360.1 (±SD 274.9), 239.5(±SD 147.3) and 45.4(±SD 34.7) respectively. Women who have illiterate husband (AOR = 3.69; 95% CI: 1.23- 11.14), pregnat women who have daily worker husband (AOR =2.02; 95% CI: 1.11-3.70), pregnat women who have merchant husband (AOR =2.42; 95% CI: 1.39,4.23), family size lesthan five (AOR =1.65; 95% CI: 1.00-2.7), and history of nausea and vomiting (AOR =2.34; 95% CI:1.17,4.67) were significantly associated with the overall nutrient intake inadequacy among pregnant women. Conclusion and recommendation: Pregnant women living in Bahir Dar city had lower nutrient intake than the recommendation level. History of nausea and vomiting, family size, ocupation of husband and educational level of husband were associated factors for nutrent intake inadequacy. Therfore; creating awarness on pregnant women and their husband about approprate ditary intake is important. Key words: pregnant women, nutrient intake, overall nutrient inadequacy, Ethiopia
