Apesar da relev\u00e2ncia do tema, os dados nacionais sobre a preval\u00eancia de dem\u00eancia em estruturas residenciais para pessoas idosas permanecem escassos.M\u00e9todos: Realizou-se um estudo transversal, observacional e de base institucional, integrado no projeto SINDIA. O estudo baseou-se num inqu\u00e9rito online dirigido \u00e0s dire\u00e7\u00f5es t\u00e9cnicas das estruturas residenciais para pessoas idosas em Portugal, conduzido entre janeiro e julho de 2024. O question\u00e1rio recolheu informa\u00e7\u00e3o sobre caracter\u00edsticas institucionais (sector, localiza\u00e7\u00e3o territorial, valor-base da mensalidade, especializa\u00e7\u00e3o em dem\u00eancia, n\u00famero total de residentes) e sobre a preval\u00eancia de dem\u00eancia diagnosticada e de decl\u00ednio cognitivo sem diagn\u00f3stico registado. As an\u00e1lises foram efetuadas com o programa R (vers\u00e3o 4.1.2), tendo sido calculadas percentagens m\u00e9dias e intervalos de confian\u00e7a a 95% (m\u00e9todo t de Student), ponderados por regi\u00e3o NUTS-2. Procedeu-se ainda a uma an\u00e1lise de clusters hier\u00e1rquica (m\u00e9todo de Ward) para identificar perfis institucionais diferenciados.Resultados: Em m\u00e9dia, 31,7% dos residentes apresentavam diagn\u00f3stico de dem\u00eancia e 22,3% suspeita de decl\u00ednio cognitivo sem diagn\u00f3stico registado, totalizando 50,2% da popula\u00e7\u00e3o residente, ap\u00f3s elimina\u00e7\u00e3o de algumas observa\u00e7\u00f5es da amostra. A propor\u00e7\u00e3o variou segundo o territ\u00f3rio, o sector institucional, o valor da mensalidade e a especializa\u00e7\u00e3o na dem\u00eancia autoidentificada. Uma an\u00e1lise de clusters revelou tr\u00eas perfis institucionais distintos, destacando-se um grupo maiorit\u00e1rio de ERPI com baixa formaliza\u00e7\u00e3o diagn\u00f3stica, sobretudo no sector solid\u00e1rio e em institui\u00e7\u00f5es com pre\u00e7os mais reduzidos.Conclus\u00e3o: Os resultados apontam para uma elevada preval\u00eancia de dem\u00eancia e de decl\u00ednio cognitivo sem diagn\u00f3stico registado em contexto de estruturas residenciais para pessoas idosas em Portugal. Estes resultados refor\u00e7am a necessidade de pol\u00edticas p\u00fablicas que promovam o diagn\u00f3stico precoce, a qualifica\u00e7\u00e3o das equipas e a redu\u00e7\u00e3o das desigualdades territoriais e institucionais na resposta \u00e0 dem\u00eancia.<\/jats:p>","DOI":"10.20344\/amp.23847","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T17:00:57Z","timestamp":1770051657000},"page":"104-113","source":"Crossref","is-referenced-by-count":1,"title":["Preval\u00eancia de Dem\u00eancia e Decl\u00ednio Cognitivo nas Estruturas Residenciais para Pessoas Idosas Portuguesas: Um Estudo Transversal"],"prefix":"10.20344","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4996-4308","authenticated-orcid":false,"given":"Miguel","family":"Padeiro","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8839-5726","authenticated-orcid":false,"given":"Fl\u00e1via","family":"Borges-Machado","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4740-7951","authenticated-orcid":false,"given":"Oscar","family":"Ribeiro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3491-7119","authenticated-orcid":false,"given":"Liliana","family":"Sousa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2712-9643","authenticated-orcid":false,"given":"Ricardo","family":"Almendra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7658-8475","authenticated-orcid":false,"given":"Paula","family":"Santana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"8464","published-online":{"date-parts":[[2026,2,2]]},"reference":[{"key":"12040","unstructured":"GBD Dementia Forecasting Collaborators.
