Introduction : Frailty is a common clinical syndrome in the elderly, which causes major health hazards, disabilities, hospitalizations, and result in high risk of mortality. Clarify their causes is of fundamental importance for the prevention of frailty and its treatment, especially for high risk groups such as the oldest old. Objectives : Associate functional decline (Activities of Daily Living - ADL) with Frailty Syndrome in the oldest old (&#8805; 90 years). Methods : The oldest-old were identified through home visits and outpatient geriatric unit of a university hospital in Porto Alegre, RS. Socioeconomic variables were evaluated, diagnosed or self-reported presence of comorbidities, self-reported falls in the previous three months, self-rated health and Katz for ADL. For data analysis, the sample was divided into two groups according to the classification of Frailty: Frail and non- Frail. Percentage differences between categorical variables (gender, marital status) were calculated by creating cross tables between the variables and tested by chi-square. The differences of the means of numerical variables were tested by ANOVA. The odds associated with the risk of having or not Frailty (dependent variable) was calculated and tested by logistic regression for variables independently observing the alpha error of 5% for statistical significance and 10% for indicative of significance. Results : A total of 36 oldest-old, 26 women and 10 men with 19 Frail and 17 non-Frail. Among the demographic variables and life habits, the weekly alcohol intake was significantly more frequent among the non-Frail. Energy expenditure and self-reported health were also significantly higher among non-Frails. While the Frail oldest old presented with a indicative of significance of larger number of comorbidities and significantly greater degree of dependence for ADL, being incontinence the most significant component. No socio-demographic and economic factor was associated with frailty. In univariate regression analysis some variables were indicative of significance (p> 0.05 and <0.1) as predictors of Fragility: self-rated health, functionality, gender, age, BMI, MMSE, weekly use of alcohol, income percapta and MET. In the final multiple regression 7 showed that weekly use of alcohol (p = 0.0451), self-rated health (p = 0.0003) and ADL (p = 0.0224) are independent determinants of Frailty in the oldest old respondents. Conclusion : Although this study has evaluated a small sample, brings a good support to as important a sample of the oldest old. It was possible to draw a functional profiling of the oldest old, having found significant differences between the groups of non-brittle and fragile. We concluded that the higher the level of functional dependence and lower self-rated health the higher was the level of frailty of the oldest old.
