XXXX status of pregnant and lactating @entity1 .

@entity1 @entity21410 @entity22782
@entity21410 nutritional status was evaluated longitudinally in 26 pregnant @entity1 (experimental group) during their third trimester of pregnancy and at 2 weeks and 3 months postpartum. Seventeen nonpregnant and nonlactating @entity1 (control group) participated at the same time intervals. All the @entity1 were assessed by the intake calculated from a reported 2-day dietary record and by fasted blood, plasma, and 24-hour urinary levels of @entity22782 determined by a radioimmunoassay. Estimated daily mean dietary @entity22782 intake and the vitamin density for the experimental group were not statistically different from those for the control group. The dietary @entity22782 intake averaged 2.75 mg/1,000 kcal. Average @entity22782 blood level of the experimental group was lower than that of the control group. No significant difference was found between the two groups in the @entity22782 levels of fasting plasma and urinary excretion. When they did not take @entity21410 supplements, members of the experimental group had intakes less than the Estimated Safe and Adequate Daily Dietary Intake and lower mean blood values than the members of the control group. This suggests that pregnant and lactating @entity1 need to consume more @entity22782 to maintain a blood vitamin level similar to that of nonpregnant @entity1 . This may be achieved by an increased caloric intake, if desirable, or by more careful selection of foods high in the nutrient.
