The purpose of this study was to investigate effectiveness of an educational intervention on pregnant women's nutritional knowledge. Despite national guidelines, women face personal and healthcare barriers to adequate nutrition education. This quasi-experimental study involved a convenience sample of pregnant women (n=27). The Nutrition Knowledge Questionnaire (NKQ) was utilized for pre and post-tests. Additionally, participants were asked open-ended questions. Data analysis was performed using paired t-tests, linear regression, and qualitative thematic analysis. The mean pre-test and post-test scores on the NKQ were 30.0 and 38.96 respectively, representing a statistically significant increase (p≤0.00). Six qualitative themes emerged including nutrition as "important" and "a real eye opener." This study validates the use of an educational intervention based on MyPlate guidelines to increase pregnant women's knowledge of nutrition.
本研究旨在探讨教育干预对孕妇营养知识的有效性。尽管有国家指南，但妇女在获得足够营养教育方面面临个人和医疗保健障碍。这项准实验研究涉及了一组方便抽样的孕妇（n=27）。使用营养知识问卷（NKQ）进行前后测试。此外，还向参与者提出了开放式问题。使用配对 t 检验、线性回归和定性主题分析进行数据分析。NKQ 的平均预测试和后测试分数分别为 30.0 和 38.96，这代表着统计学上的显著增加（p≤0.00）。出现了六个定性主题，包括营养是“重要的”和“真正的大开眼界”。这项研究验证了基于 MyPlate 指南的教育干预措施在增加孕妇营养知识方面的有效性。
