O presente estudo tem por objetivo analisar a associação entre os níveis plasmáticos de Vitamina D (VitD) e o estado funcional em pessoas idosas com ou sem défice cognitivo residentes num Lar. Este estudo transversal incluiu 14 homens e 31 mulheres com idade ≥ 65 anos. A função cognitiva foi avaliada através da pontuação obtida pela ferramenta Mini Mental Status Examination (MMSE®). A autonomia nas atividades de vida diária foi avaliada com base na pontuação obtida pelo Índice de Barthel (IB®). O risco de queda foi determinado a partir da pontuação obtida pela Escala de Morse (EB®). Os níveis plasmáticos de VitD foram medidos utilizando a técnica laboratorial The Enzyme-Linked Immunosorbent Assay (E.L.I.S.A). Mais de metade dos participantes eram mulheres (68,8%). Quarenta e quatro participantes (97,7%) apresentavam hipovitaminose D. Do total da amostra (n=45), vinte e cinco participantes (55,5%) apresentaram défice grave em VitD (<10ng/mL). Observaram-se diferenças significativas para os níveis plasmáticos de VitD entre os participantes com ou sem deficiência cognitiva (P=0,004). Os participantes com défice cognitivo mostraram uma associação significativa entre a pontuação obtida no IB e o nível plasmático de VitD (P=0,024), em comparação com os participantes sem défice cognitivo (P=0,438). Em conclusão, os nossos resultados sugerem que a hipovitaminose D é muito frequente nas pessoas idosas com ou sem défice cognitivo (97,7%). É de realçar que todas as pessoas idosas com défice cognitivo apresentavam pior autonomia (100%) em comparação com as pessoas idosas sem défice cognitivo (44,4%). No grupo das pessoas idosas com défice cognitivo foi possível observar uma associação entre a autonomia nas atividades de vida diária determinada pelo Índice de Barthel (IB®) e os níveis plasmáticos de VitD.
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.
