OBJETIVO: Realizar revisão integrativa de literatura sobre epidemiologia de quedas entre idosos no Brasil, buscando identificar taxa de ocorrência, recorrência e fatores potencialmente modificávies associados a esses episódios. MÉTODO: Foi efetuada revisão de literatura, consistindo na busca de artigos científicos das bases de dados Literatura Internacional em Ciências da Saúde (MEDLINE), Scientific Electronic Library Online (SciELO) e Centro Latino-Americano e do Caribe de Informação em Ciências da Saúde (LILACS) em 14 de novembro de 2017. Os artigos foram selecionados a partir das seguintes palavraschave: "Acidentes por quedas" E/OU "Idoso" E/OU "Brasil". Dados epidemiológicos foram extraídos dos estudos primários e comparados. RESULTADOS: Foram selecionados 35 artigos. A maioria dos estudos foi realizada nas regiões Sudeste (15) e Sul (11). A taxa de ocorrência de quedas variou entre 10,7 e 59,3%. O domicílio, no período diurno, é o cenário mais frequente de quedas. As circunstâncias mais comumente descritas são tropeço, escorregão, tontura e existência de desnível, ocasionando tombo da própria altura. Os fatores mais frequentemente associados às quedas foram sexo feminino, idade maior que 80 anos, déficit cognitivo e sintomas depressivos. As consequências identificadas foram fraturas e o medo de cair novamente. CONCLUSÃO: Alguns fatores associados aos tombos em idosos no Brasil são modificáveis e prevenir as quedas pode possibilitar a redução da morbimortalidade nessa população.
The identification of the prevalence of cognitive impairment and associated
factors among older adults is important in countries facing rapid demographic
transition, given the significant implications for public policy and health
planning.ObjectiveTo determine the prevalence of functional cognitive impairment (FCI) and
associated factors in Brazilian community-dwelling older adults.MethodsA cross-sectional study involving 461 elderly subjects residing in Fortaleza
city, Ceará was conducted. Cognitive assessment was performed using
three tests: the MMSE (Mini-Mental State Examination), VF (Verbal Fluency)
and CT (Clock Test). The functional capacity evaluation was based on a
survey of 21 basic and instrumental activities of daily living (ADLs).
Cognitive impairment was defined by MMSE cut-off points adjusted for
literacy. Functional impairment was defined as dependency to carry out more
than four ADLs.ResultsThe prevalence of FCI was 13.64% (95% CI: 10.33 to 16.64%). FCI was
proportionally associated with age with OR=2.24 (95% CI: 1.04 to 4.79) for
individuals aged 70 to 79 years and OR=8.27 (95 % CI: 4.27 to 16.4) for
those aged 80 to 100 years. FCI was associated with self-reported diseases
including hypertension OR=2.06 (95% CI: 1.17 to 3.65), stroke OR=2.88 (95%
CI: 1.66 to 5.00) and acute myocardial infarction OR=2.94 (95% CI: 1.59 to
5.42). The occurrence of FCI was proportionally correlated with the number
of drugs used.ConclusionFunctional cognitive impairment is a prevalent condition in Brazilian
community-dwelling older adults and its occurrence is associated with age,
number of drugs used, and vascular morbidities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
