Aging can be associated with poor dietary intake, reduced nutrient absorption and less efficient utilization of nutrients. Loss of memory and related cognitive function are also common among elderly. A cross-sectional study was conducted on a long-term care population to evaluate: (1) The prevalence of inadequate vitamin status; (2) The relationship between cognitive function and vitamin status; (3) The effect of medications which alter gastric acid levels on vitamin B12 and homocysteine (Hcy) status; (4) The adequacy of vitamin status among vitamin supplement users compared to supplement non-users. Blood measures of vitamins B12, B6, erythrocyte folate, Hcy and niacin were evaluated. The Standardized Mini-Mental State Examination was used to assess cognitive function. Seventy-five residents participated; mean age of 80.7 (+/-11.5) years, ranging from 48 to 100 years. The prevalence of inadequate vitamin status was as follows: B12 ≤ 221 pmol/L (31/75 or 41.3%); erythrocyte folate < 370 nmol/L (1/75 or 1.3%); B6 ≤ 30 nmol/L (4/75 or 5.3%); Hcy > 13.3 mumol/L (31/75 or 41.3%); niacin ratio ≤1 (20/75 or 26.7%). No significant differences in B12 and Hcy status were seen between users and non-users of medications known to affect gastric acid levels. Vitamin status did not significantly differ between groups categorized as having marked (n = 44), mild (n = 14) or normal (n = 9) cognitive function. Vitamin supplement users (n = 29) had more adequate mean levels of B12 (p < 0.0001), erythrocyte folate (p < 0.05) and Hcy (p < 0.01) compared to non-users of supplements (n = 47).
