Abstract: Introduction: Dietary diversity is essential for maternal health and pregnancy outcome. A diverse diet provides micronutrients essential for a health pregnancy and foetus. The first 1000 days are critical for child development. The aim of this research was to systematically review studies to determine the association of dietary diversity, nutrient intake and the nutritional status of the pregnant women. Methods: The search for the articles included a search on Google scholar, PubMed and Freefull pdf using a pre-defined inclusion and exclusion criteria. The identified papers were 87. Reference lists of identified papers were also examined. The key words used nutrient intake, nutritional status and minimum dietary diversity score. Most of the articles identified were specifically about dietary diversity and how it determines nutritional status especially to pregnant women. All papers on dietary diversity and determinants in households were considered. Results: A total of 87 articles were identified for screening. A total of 20 out of 87 identified were relevant to dietary diversity, nutrient intake and nutritional status of pregnant mothers aged 18-45 years. Dietary diversity is a proxy indicator of nutrient intake as demonstrated by a variety of studies. However, some studies reported insignificant relationship between maternal dietary diversity and nutritional status. Demographic and socio-economic status was demonstrated to influence dietary diversity despite disagreement from other studies. Conclusions: Dietary diversity influences maternal nutritional status and pregnancy outcome. Public health nutrition interventions involving improving accessibility of affordable nutrient rich foods and fortification of common foods are needed to bolster efforts to improve maternal nutrition in developing countries.
