RESUMEN
INTRODUCTION: Disability follows the rapid rate of population ageing, imposing a huge burden on society. Functional assessment in older people can identify predictors of disability. OBJECTIVE: Analyze the incidence and the risk factors for disability in activities of daily living (ADL) and instrumental activities of daily living (IADL) in older adults over six years. METHODS: Six year-follow up study initiated in 2010. The baseline non-probabilistic sample consisted of 180 independent community dwelling individuals aged 60 and over. The procedures comprised an interview with sociodemographic data, questions about falls, urinary incontinence, self-rated health, and assessment of ADL, IADL, mobility, depression, vision, hearing, cognition, nutrition, grip strength and social support. The second research was carried out by telephone and assessed ADL and IADL. Logistic regression models calculated the odds of disability in ADL and IADL according to the age, sex and all other variables. RESULTS: At six-year follow-up, 118 participants were still alive (65.6%), 31 died (17%) and other 31 were missed (17%). The incidence of disability to performADL and IADL were 25.4% and 32.3%, respectively. The regression logistic models revealed thaturinary incontinence (OR = 3.2; P = 0.03) and insufficient emotional support (OR = 3.8; P = 0.04) were associated with ADL disability, while visual problems (OR: 2.9; P = 0.03) and insufficient emotional support (OR: 5.6; P = 0.01) were associated with IADL disability. CONCLUSION: The current study has identified that insufficient emotional support, visual problems and urinary incontinence are associated with disability in older adults. The routine assessment of these problems in the primary care clinics enable the implementation of strategies aimed at reducing or postponing disability. Educating patients and families will also enable better choices to reduce the risk of functional decline.
