Background
A minimum acceptable diet for children aged 6–23 months is limited globally, with Ethiopia’s proportion reducing to one in nine. This study was aimed to assess the prevalence of the minimum acceptable diet and associated factors among children aged 6–23 months in Dera town, Oromia, Ethiopia.
Methods
A community-based cross-sectional study was conducted. Systematic random sampling techniques were used to select the study subjects. The data was coded, entered into Epi-Info version 7, and then exported to SPSS version 24 for analysis. The variance inflation factor and tolerance test are used to check multicollinearity. Descriptive statistics of frequency (%) were used. Hosmer and Lemeshow’s goodness-of-fit test at a P-value > 0.05 is considered the model fit. Bivariate and multivariate logistic regression analyses were computed with a 95% confidence interval, and a P-value < 0.05 was, considered statistically significant.
Results
A total of 430 study subjects were included in this study. The prevalence of a minimum acceptable diet was 36.5% (95% confidence interval (CI): 32, 41%). In the adjusted model, mothers attaining a primary school (adjusted odds ratio (AOR) = 2.7, 95%CI: 1.3, 4.8), college and above education (AOR = 4.3, 95%CI: 1.4, 13), child age between 12–17 months (AOR = 6.2, 95%CI: 2.80, 13.50) and 18–23 months (AOR = 4.61, 95%CI: 2.04, 10.40), ANC visit four or more (AOR = 2.0, 95%CI: 1.2, 3.4), and not feeding breast (AOR = 0.15, 95% CI: 0.07, 0.31) were significantly associated with meeting the minimum acceptable diet.
Conclusion
This study showed that the practice of a minimum acceptable diet was low, according to the World Food Program target. Mothers’ educational status, antenatal care visits, age of the child, and breastfeeding were the predictors of the minimum acceptable diet.

背景：全球范围内6~23月龄儿童的最低合理膳食（minimum acceptable diet）达标率普遍偏低，埃塞俄比亚的该比例已降至九分之一。本研究旨在评估埃塞俄比亚奥罗米亚州德拉镇6~23月龄儿童的最低合理膳食达标率及其相关影响因素。
方法：本研究采用基于社区的横断面研究设计。通过系统随机抽样方法选取研究对象。数据经编码后录入Epi Info 7版本软件，随后导出至SPSS 24版本软件开展统计分析。采用方差膨胀因子与容差检验评估多重共线性。以频数（百分比）作为描述性统计指标。以P值>0.05作为模型拟合良好的判定标准，通过Hosmer-Lemeshow拟合优度检验进行验证。采用95%置信区间（CI）开展单因素与多因素logistic回归分析，以P值<0.05作为差异具有统计学意义的判定阈值。
结果：本研究共纳入430名研究对象。最低合理膳食达标率为36.5%（95%置信区间(CI)：32, 41%）。在校正后的多因素模型中，母亲完成小学学业（校正比值比(adjusted odds ratio, AOR)=2.7，95%CI: 1.3, 4.8）、拥有大学及以上学历（AOR=4.3，95%CI: 1.4, 13）、儿童年龄处于12~17月龄（AOR=6.2，95%CI: 2.80, 13.50）与18~23月龄（AOR=4.61，95%CI: 2.04, 10.40）、产前检查（Antenatal Care, ANC）次数≥4次（AOR=2.0，95%CI: 1.2, 3.4）以及未进行母乳喂养（AOR=0.15，95%CI: 0.07, 0.31）均与最低合理膳食达标情况显著相关。
结论：本研究显示，参照世界粮食计划署（World Food Program, WFP）的标准，当地儿童最低合理膳食的践行率偏低。母亲的受教育程度、产前检查次数、儿童年龄以及母乳喂养情况均为影响最低合理膳食达标的预测因素。
