Nutrition Education Models in Pregnancy to Increase Knowledge and Dietary Patterns: A Systematic Review

Abstract

Background. The misconception of nutritional principles causes dietary oversight, resulting in an excess or deficit of energy and specific nutrients essential for the proper course of pregnancy and a child’s healthy growth. This review aims to evaluate the effectiveness of nutrition education in improving knowledge and dietary change conducted in pregnant women. Methods. This review study complies with the 2009 PRISMA guidelines. The studies included in this review are mainly studies with experimental designs. Databases used in searching relevant literatures such as PubMed, ScienceDirect, Willey online Library, Web of Science, Cochrane, and Proquest that were published from 2010 to 2021, full text, English version, experimental studies. Two review authors conducted studies screening based on the eligibility criteria, and extracted important points in the studies included. Quality of the studies included were assessed using EPHPP. Results. A total of 10 studies were identified in this review. Six studies in the high quality, and four studies in moderate quality. Overall outcomes of the studies included are Knowledge, Attitude, practice, dietary practice, awareness, hemoglobin blood level, and Gestational Weight Gain (GWG). Conclusion. Nutrition education in many methods has a power to improve knowledge, and dietary change of pregnant women. It implies the need for future large high quality trials using a standardized approach to measuring and reporting similar findings across studies.
