Prevalence and factors associated with low functionality in elderly
Prevalencia y factores asociados a baja funcionalidad en anciano
Prevalência e fatores associados à baixa funcionalidade em idosos
Abstract (en)
This cross-sectional, exploratory study aimed to estimate the prevalence of low functionality and identify associated factors in community-dwelling older adults aged ≥ 60 years in southwestern Bahia, Brazil, using a sample of 218 participants. Associations between low functionality and independent variables were examined through crude analyses; variables with p ≤ 0.20 were retained for the adjusted model. Adjusted analyses were conducted using Poisson regression with robust variance to estimate prevalence ratios (PR) and 95 % confidence intervals (95 % CI). The prevalence of low functionality was 39 % (n = 85). Hospitalization (PR = 0.65; 95 % CI = 0.47 – 0.89; p < 0.001), basic activities of daily living (BADL) (PR = 0.55; 95 % CI = 0.41 – 0.74; p < 0.001) and cognitive status assessed through the Mini-Mental State Examination (MMSE) (PR = 0.49; 95 % CI = 0.30 – 0.82; p < 0.001) were positively associated with functionality.
Abstract (es)
Este estudio exploratorio transversal tuvo como objetivo estimar la prevalencia de baja funcionalidad e identificar los factores asociados en adultos mayores ≥ 60 años habitantes de la comunidad, en el suroeste de Bahía, Brasil, con una muestra de 218 participantes. La asociación entre la baja funcionalidad y las variables independientes se verificó mediante análisis de datos crudos; aquellas variables con significancia estadística de al menos 20 % (p ≤ 0.20) se mantuvieron para el análisis ajustado mediante regresión de Poisson, con estimación robusta de las razones de prevalencia (RP) y sus intervalos de confianza del 95 % (IC95 %). La prevalencia de baja funcionalidad fue del 39 % (n = 85). La hospitalización (RP = 0.65; IC95 % = 0.47 – 0.89; p < 0.001), las actividades básicas de la vida diaria (ABVD) (RP = 0.55; IC95 % = 0.41 – 0.74; p < 0.001) y el estado cognitivo evaluado a través del Mini-Examen del Estado Mental (MMSE) (RP = 0.49; IC95 % = 0.30 – 0.82; p < 0.001) estuvieron asociados positivamente con la funcionalidad.
Abstract (pt)
Foi realizado um estudo transversal exploratório para estimar a prevalência e identificar fatores associados à baixa funcionalidade em peessoas idosas comunitários com idade ≥ 60 anos. Este estudo foi realizado no sudoeste da Bahia, com uma amostra de 218 participantes. A associação entre baixa funcionalidade e variáveis independentes foi verificada por análises brutas com significância estatística de pelo menos 20 % (p ≤ 0.20) para permanecer na análise ajustada por meio da regressão de Poisson, com cálculo robusto de razões de prevalência (RP) e intervalos de confiança de 95 % (IC 95 %). A prevalência de baixa funcionalidade foi de 39 % (n = 85). Hospitalização (RP = 0.65; IC95 % = 0.47 – 0.89; p < 0.001), atividades básicas da vida diária (ABVD) (RP = 0.55; IC95 % = 0.41 – 0.74; p < 0.001) e Mini-Exame do Estado Mental (MEEM) (RP = 0.49; IC95 % = 0.30 – 0.82; p < 0.001) foram positivamente associados à funcionalidade.
