In a Maternal & Child Nutrition analysis of published studies on the dietary habits of women who were trying to conceive or were pregnant, most studies indicated that women do not meet nutritional recommendations for vegetable, cereal grain, or folate intake. Pregnant women did not meet iron or calcium intake requirements in 91% and 55% of studies, respectively, and also exceeded fat intake recommendations in 55% of studies. Higher level education was associated with improved adherence to dietary guidelines in pregnant women, and older age and non-smoking status were associated with greater guideline adherence in both preconceptual and pregnant women.
