B12 deficiency: Symptoms can include this ‘subtle’ change

Vitamin B12 Vitamin B12 is vital for the body to produce healthy red blood cells. It also is needed for proper nerve function and DNA

Article Description

Vitamin B (B12) deficiency, although treatable, impacts up to 43% of community-living older adults; long-term care (LTC) residents may be at greater risk. Recommendations for screening require further evidence on prevalence and incidence in LTC. Small, ungeneralizable samples provide a limited perspective on these issues. The purposes of this study were to report prevalence of B deficiency at admission to LTC, incidence 1 year post-admission, and identify subgroups with differential risk. This multi-site (8), retrospective prevalence study used random proportionate sampling of resident charts (n = 412). Data at admission extracted included demographics, B status, B supplementation, medications, diagnoses, functional indepen- dence, cognitive performance, and nutrition. Prevalence at admission of B12 deficiency (<156 pmol/L) was 13.8%; 47.6% had normal B (>300 pmol/L). One year post-admission incidence was 4%. Better B status was significantly associated with supplementation use prior to LTC admission. Other characteristics were not associated with status. This work provides a better estimate of B deficiency prevalence than previously available for LTC, upon which to base protocols and policy. Prospective studies are needed to establish treatment efficacy and effect on health related outcomes.
