Association between serum vitamin B12 level and frailty in older adults

摘要

OBJECTIVE:Frailty is associated with recurrent falls, fractures, limitation of daily living activities, cognitive impairment, increase in hospitalization, placement in nursing home, and mortality rate in older adults. Although malnutrition is one of the most important etiological factors, role of micronutrients is unclear. The aim of this study was to investigate association between frailty and vitamin B12, which has been demonstrated to be related to numerous geriatric syndromes.
