Serum Vitamin B₁₂, C and Folate Concentrations in the New Mexico Elder Health Survey: Correlations with Cognitive and Affective Functions

Abstract

Hispanics, even after adjustments for gender, age, vitamin supplementation, vitamin content of dietary foods, education and household income, had lower serum concentrations of B12, C and folate than NHW. The most significant associations observed were those between serum folate and various measures of cognitive function, even after adjusting for presence of depression.
