CURRENT NUTRITION ISSUES: EFFECT OF BRAN OR MULTIVITAMIN-MINERAL SUPPLEMENTS ON VITAMIN B(,12) STATUS, COUNSELING SKILLS OF NUTRITION STUDENTS, AND BREASTFEEDING DURATION OF WIC MOTHERS
Abstract
Four projects were conducted. In the first project urinary vitamin B(,12) excretion of 41 omnivore and vegetarian subjects was measured using a microbiological assay when subjects consumed controlled vegan, lactovegetarian and omnivore diets supplemented with bran. Subjects' mean calculated vitamin B(,12) intake was 2.48 ug/day while consuming self-selected diets and 6.83 ug/day while consuming controlled diets. Mean urinary vitamin B(,12) excretion was 1.13 ug/day during the self-selected diet period and 0.93 ug/day during the controlled diet periods. The lowest urinary vitamin B(,12) excretion occurred when white bran was added to the controlled diets; however, the effect was not significant. In project two, thirteen adult women consuming self-selected diets were given a multivitamin-mineral supplement for 5 days or no supplement for 5 days in a cross-over design. Urinary vitamin B(,12) was measured as in project one. Mean urinary vitamin B(,12) excretions during the presupplemented period, the supplemented period and post-supplemented period were 0.028, 0.397 and 1.867 ug/day, respectively. Mean calculated vitamin B(,12) intake from self-selected diets was 1.93 ug/day. In project three, 34 nutrition students were videotaped before and after a counseling skills workshop. Twenty-four students (experimental group) attended the three-hour workshop and 10 students (control group) did not attend the workshop. Each videotape was evaluated by two registered dietitians. Eight counseling behaviors were used significantly more by experimental group students than by control group students following the workshop. Project four included a telephone survey of 45 WIC mothers to identify factors related to duration of breastfeeding and to evaluate an intervention designed to extend breastfeeding of these mothers. Late introduction of formula, positive attitude toward breastfeeding, previous breastfeeding experience and father in the home increased breastfeeding duration. The correlation of previous breastfeeding experience with positive attitude toward breastfeeding was significant. Experimental group mothers (N = 13) who received additional education and postpartum support via two telephone calls, responded more positively than control group mothers (N = 15) to two attitude statements and were less likely than control mothers to introduce formula because of lack of breastmilk.
