To investigate the relationship between dietary nutrition and health care of pregnant women during pregnancy and the health of mothers and infants, and to supply a reference for healthy diet and nutritional hygiene of clinical pregnant women. A total of 168 pregnant women who voluntarily accepted personalized nutritional diet guidance during pregnancy within one year were selected as observation groups, and 168 cases were randomly selected from pregnant women with internal files in the same period as the control group, and the clinical data of pregnant women in the two groups were sorted and analyzed. A total of 168 pregnant women in the observation group had 3 cases of gestational hypertension, 1 case of CDM, 1 case of IGM, 5 cases of anemia during pregnancy, 2 cases of amniotic fluid abnormalities, 0 cases of fetal intrauterine development restriction, 0 cases of preterm infants, 3 cases of macroscopy, 21 cases of caesarean section, 2 cases of postpartum hemorrhage, while the control group had 16 cases of PIA, 6 cases of GDM, 8 cases of IGM, 39 cases of anemia during pregnancy, 11 cases of amniotic fluid abnormalities, and 7 cases of preterm infants with limited intrauterine development. In 12 cases of macrosomia, 53 cases of caesarean section, and 10 cases of postpartum hemorrhage, the difference in the incidence of complications in each of the two groups was statistically significant (P<0.05), while the difference between the two groups was not obvious and statistically meaningless (P>0.05). Reasonable diet and nutrition have important positive significance for the health care of pregnant women during pregnancy and can reduce the incidence of pregnancy complications and macrosomia.
