This double cohort study aimed to evaluate the effect of tailored dietary guidance for pregnant women on dietary intake, nutritional status, and infant birth weight. Healthy pregnant women were recruited at an antenatal clinic during two phases over 2 years. The historical controls were analyzed a year prior to the intervention group. In both groups, data were collected at 19–26 gestational weeks (baseline) and at 34–37 gestational weeks (outcome measurement). The intervention included the following: (a) assessments of maternal dietary nutritional intake using the brief self‐administered diet history questionnaire, (b) individual feedback based on the assessments of maternal nutritional status, (c) tailored guidance for a healthy diet, (d) original cooking recipes, and (e) goal sharing. Mann–Whitney U test was used to compare the outcome data between the groups. Of the 378 eligible women, 309 women had follow‐up questionnaire data. Blood samples were obtained from 202 women. Despite a lack of improvement in reported dietary intake, plasma eicosapentaenoic acid ( p = .002), docosahexaenoic acid ( p < .001), arachidonic acid ( p < .001), and dihomo‐gamma‐linolenic acid ( p < .001) concentrations as well as maternal weight gain ( p = .019) were significantly higher in the intervention group. However, serum folate ( p = .031) concentration was significantly lower in the intervention group, and there were no significant differences between the groups in 25‐hydroxy vitamin D levels, blood count, average birth weight, and rate of low birth weight infants. Assessment‐based tailored guidance individualized to maternal dietary intake might partially contribute to improved nutrition in pregnant women.
