| الوصف: | Older adults have potential increased risk of nutrient deficiencies because of age-related decreased dietary intake and malabsorption; it is important to ensure nutrient needs are met to avoid adverse health outcomes. B vitamins are of particular interest: vitamin B12deficiency can cause irreversible neurodegeneration; there is mandatory folic acid fortification in Canada; and suboptimal riboflavin status has been reported among older adults in the United Kingdom. In this exploratory secondary analysis study we assessed vitamin B12and riboflavin biochemical status (via microparticle enzyme immunoassay and erythrocyte glutathione reductase activity coefficient (EGRac), respectively), and the vitamin B12, riboflavin, and folate content of menus served to a convenience sample of older adults (≥65 years) from 5 residential care facilities within the Lower Mainland of British Columbia, Canada. Diet was assessed from customized 28-day cycle meal plans. Participants (n = 207; 53 men and 154 women) were aged 86 ± 7 years, largely of European descent (92%), and nonsmokers (95%). The menus served had a low prevalence of inadequacy for vitamin B12and riboflavin (only 4% and 1% of menus contained less than the estimated average requirement (EAR), respectively), but 93% contained less than the EAR for folate. Mean ± SD serum total vitamin B12concentration was 422 ± 209 pmol/L, and EGRac was 1.30 ± 0.19. The majority of older adults in residential care were provided with adequate vitamin B12and riboflavin menu amounts, and only 5% were vitamin B12deficient ( |
