Abstract

Study aims to examine the relationship between serum Vitamin D (VitD) and the functional status on elderly people with or without cognitive impairment living in nursing home. This cross-sectional study included 14 men and 31 women aged ≥ 65 years. Cognitive impairment was evaluated through the Mini-Mental State Examination (MMSE®) tool score. Autonomy in activities of daily living was assessed with the Barthel Index (BI®) score. The risk of falls was determined with the Morse Scale score. Serum VitD levels were measured using The Enzyme-Linked Immunosorbent Assay (E.L.I.S.A) protocols of the clinical laboratory of the research. More than half of the participants were women (68.8%). Forty-four participants (97.7%) were identified with hypovitaminosis D. Out of 45 participants, twenty-five participants (55.5%) showed a severe deficit in VitD (<10ng/mL). Significant differences for the serum levels VitD were observed between participants with or without cognitive impairments (P=0.004). Participants with cognitive impairment showed a significant association between the BI® score and the VitD serum level (P=0.024), compared to the participants without cognitive impairment (P=0.438). In conclusion, our results suggests that hypovitaminosis D is highly prevalent among elderly people with or without cognitive impairment living in nursing home (97.7%). All cognitive impairment participants showed worst autonomy (100%) compared to the participants without cognitive impairment (44.4%). Association between autonomy and VitD serum level was found in the cognitive impairment participants.
