Equilíbrio postural e fatores associados ao risco de quedas em idosos com diabetes mellitus tipo 2 / Postural balance and associated factors with the fall risk assessed in older adults with type 2 diabetes mellitus

Resumo Objetivo Identificar os fatores clínico-funcionais associados ao risco de quedas, avaliado pelo Mini-BESTest, em idosos com diabetes mellitus tipo 2 (DM2). Método Trata-se de um estudo transversal. Um total de 145 idosos com idade =60 anos foram avaliados por meio das variáveis sociodemográficas (sexo, faixa etária, estado civil, nível de educação e percepção geral da saúde, audição e visão) Mini-BESTest, Mini-Mental State Examination (MMSE), Escala de Depressão Geriátrica (GDS-15) e o teste Timed Up and Go (TUG) (dupla tarefa). Foi utilizado um modelo de regressão logística múltipla. Resultados O domínio de orientação sensorial apresentou a pontuação média mais elevada, seguido pelos domínios estabilidade na marcha, ajustes posturais antecipatórios e respostas posturais. Os fatores associados ao risco de quedas em idosos foram: percepção visual ruim/muito ruim OR 3.40 (1,50-7,72); presença de doenças respiratórias OR 8.00 (1,32-48,46); sensação de tontura OR 2.53 (1,10-5,80); e tempo do teste Timed Up and Go (TUG) (dupla tarefa) igual ou superior a 13,5 segundos OR 3.31 (1,03-10,64). Conclusão Os idosos deste estudo apresentaram um equilíbrio postural comprometido, principalmente no domínio das respostas posturais. O conhecimento dos fatores associados ao risco de quedas em idosos com DM2 permite uma orientação mais eficaz na avaliação, prevenção e intervenção, visando minimizar a ocorrência de quedas e preservar ou otimizar o equilíbrio postural. Diversos fatores influenciaram esse resultado, tais como sobrepeso, baixa atividade física e nível educacional, várias comorbidades, polifarmácia, diagnóstico de DM2 por mais de dez anos, percepção negativa da saúde geral e da visão, e sintomas depressivos.

Abstract Objective Identify clinical-functional factors associated to the risk of falls, assessed by Mini-BESTest in older adults with type 2 diabetes mellitus (T2DM). Method This cross-sectional study. A total of 145 older adults aged ≥60 years were evaluated through sociodemographic variables (sex, age group, married, education level, general health status hearing and vision), Mini-BESTest, Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS-15) and dual-task Timed Up and Go Test (TUG) Multiple logistic regression model was used. Results The sensory orientation domain presented the highest average score, followed by the gait stability, anticipatory postural adjustments and postural responses domains. Factors associated to the risk of falls in older adults are: poor/very poor visual perception OR 3.40 (1.50-7.72); have respiratory diseases OR 8.00 (1.32-48.46); feeling dizzy OR 2.53 (1.10-5.80); and TUGT (dual task) time equal to or greater than 13.5 seconds OR 3.31 (1.03-10.64). Conclusion Older adults in this study presented impaired postural balance, mainly in the postural responses domain. The knowledge of the factors associated with the risk of falls in older adults with T2DM allows for better guidance in prevention, assessment and intervention, in order to minimize the occurrence of falls and maintain or optimize postural balance. Several factors influenced this outcome, such as overweight, low physical activity and education, several comorbidities, polypharmacy, T2DM diagnosis for more than ten years, negative perception of general health and vision, and depressive symptoms.

Factors related to depressive symptoms in older adult patients with type 2 Diabetes Mellitus.

BACKGROUND: The association of type 2 Diabetes Mellitus (DM2) with depressive symptoms may affect the quality of life of older adults and increase their risk of morbidity and deterioration in functional activities. This study aimed to investigate the variables related to depressive symptoms in older adult patients with DM2. METHODS: This cross-sectional, descriptive, analytical study included 102 older adult patients with DM2, treated in northeastern Brazil. We evaluated demographic, clinical, and functional variables [Timed Up and Go (TUG) test, a scale to assess performance (WHO Disability Assessment Schedule), and psycho-cognitive variables (using the Mini Mental State Examination (MMSE) and Geriatric Depression Scale (GDS)). RESULTS: There was a significant correlation between the GDS and body mass index (p = 0.04, ρ = 0.20) and intensity of pain (p = 0.09, ρ = 0.26); and scores on the MMSE (p = 0.01, ρ = -0.25); WHODAS (p < 0.001, ρ = 0.61); TUG test (p = 0.016, ρ = 0.25), and TUG dual task (p = 0.029, ρ = 0.23). CONCLUSION: Depressive symptoms in older adult patients with DM2 were associated with being female, being single, being illiterate, having poor overall health, using a walking aid, having higher body mass index, having a greater intensity of dizziness, exhibiting functional impairment, and having gait and cognition deficits.
