Abstract Objective: To explore the influence of dietary nutrition interventions on dietary nutrition intake and maternal and infant outcomes of pregnant women. Methods: 300 pregnant women were randomly divided into observation group and control group (150 cases in each group) from September 2017 to September 2018. The woman in the control group had received routine dietary guidance, and the women in the observation group were given individualized dietary nutrition guidance. The situations of dietary nutrition intake and pregnancy outcomes of women were compared between the two groups. Results: The fat and sodium levels of women in the observation group were significant lower than those of women in the control group (P<0.05), but the levels of protein, calcium, iron, zinc, folic acid and vitamin A were significant higher (P<0.05). There were no significant difference in carbohydrate level, gestational weeks, rates of gestational hypertension and premature rupture of membranes of women, Apgar score, neonatal birth weight, and preterm birth rate between the two groups (P>0.05). The different value of BMI, and the incidences of gestational diabetes and anemia, polyhydramnios or oligohydramnios, cesarean section, and postpartum hemorrhage of women, and low body mass, macrosomia and fetal distress rates in observation group were significant lower than those of women in the control group (P<0.05). Conclusion: Individualized dietary nutrition intervention during pregnancy can improve the nutritional status of women, and can improve maternal and infant outcomes.
