    (2021-01-08) Morris, Margaret; Pearce, Robyn; Berg, Jade; Bilgin, Ayse A.; Vos, Paul; Grant, Ross; Pawlak, Roman

    Background/Aims: Vegetarians have a high risk of abnormal vitamin B-12 (B-12), and homocysteine (Hcy), status. The objectives included assessment of: 1) folate, B-12, and Hcy status; 2) incidence rate of abnormal folate, B-12, and Hcy; and 3) associations between folate and B-12 with Hcy status among vegetarian and non-vegetarian adolescents.

    Methods: A cross-sectional plasma folate, B-12, and Hcyassessment in 49 vegetarian and 639 non-vegetarian, 14-17 year-old, participants from New South Wales, Australia.

    Results: Mean (range) folate (nmol/L), B-12 (pmol/L), and Hcy (μmol/L), were: 33.4 (9.57-101) vs. 27.7 (2.7-86), p=0.033; 287.81 (134-702) vs. 392.22 (119-1300), p

    Conclusions: B-12 is a nutrient of a concern for vegetarian teenagers. To improve B-12 status, vegetarian adolescents should consume foods fortified with B-12, and/or take B-12 supplements.
