20.500.12556/RUL-178435 Dietary intake and status of vitamin B12 in Slovenian population Vitamin B12 deficiency poses a health concern, especially in vulnerable populations. Dietary vitamin B12 intake was obtained by two 24 h dietary recalls and food propensity questionnaires in a representative Slovenian cross-sectional food consumption survey, SI.Menu (n = 1248 subjects; 10–74 years). For a subgroup of 280 participants, data on serum vitamin B12 were available through the Nutrihealth study. The estimated usual population-weighted mean daily vitamin B12 intakes were 6.2 µg (adults), 5.4 µg (adolescents), and 5.0 µg (elderly). Lower intakes were observed in females. Inadequate daily vitamin B12 intake (<4 µg) was detected in 37.3% of adolescents, 31.7% of adults, and 58.3% elderlies. The significant predictors for inadequate daily vitamin B12 intake were physical activity score in all age groups, sex in adolescents and adults, financial status and smoking in elderly, and employment in adults. Meat (products), followed by milk (products), made the highest vitamin B12 contribution in all age groups. In adolescents, another important vitamin B12 contributor was cereals. The mean population-weighted serum vitamin B12 levels were 322.1 pmol/L (adults) and 287.3 pmol/L (elderly). Low serum vitamin B12 concentration (<148 nmol/L) and high serum homocysteine (>15 µmol/L) were used as criteria for vitamin B12 deficiency. The highest deficiency prevalence was found in elderlies (7.0%), particularly in males (7.9%). Factors associated with high serum homocysteine were also investigated. In conclusion, although vitamin B12 status was generally not critical, additional attention should be focused particularly to the elderly. vitamin B12 deficiency homocysteine folate EU menu pomanjkanje homocistein folati true false true Angleški jezik Slovenski jezik Članek v reviji 2026-01-28 04:39:24 2026-01-30 11:38:50 2026-04-17 04:53:09 0000-00-00 00:00:00 2022 0 0 22 str. iss. 2 Vol. 14 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 577.16:613.292 2072-6643 10.3390/nu14020334 93577219 RAZ_Lavrisa_Ziva_2022.pdf RAZ_Lavrisa_Ziva_2022.pdf 1 E98F1D898B709DCFDD5845B0BF450779 2134f3780f5e38f9ca7f4990889241dd7f002189ced2402eef6b62dedaeb3c5d 4f795589-2e8f-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=231749 https://www.mdpi.com/2072-6643/14/2/334 1 ef676532-fbfa-11f0-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=226320 Medicinska fakulteta 0 0 0
