| Özet: | The main objectives of this work were: to verify the prevalence of functionaldisability (FD) inthe basic activities of daily living (BADL) and its associated factors (Study 1) and verify the incidence of functional decline and predictor factors of functional decline (Study 2) in institutionalized older people. The sample of the study was formed by individuals aged 60 years and over belonging to 10 nursing homes (NH) in Natal/RN, being excluded hospitalized or palliative care residents. The Study 1 is a cross-sectional study (October-December 2013) and FD was evaluated by Katz scale and characterized when there was limitation in one or more BADL (eating, sphincter control, transferring, personal hygiene, dressing and bathing). As independent variables sociodemographic, instituition-related health-related variables were considered. The Chi-square test, Fisher's exact test or the linear Chi-square test for the bivariate analysis and logistic regression for multivariate analysis were applied. The sample consisted of 321 individuals and the prevalence of FD was 72.9% (95% CI: 67.8-77.5%). The most affected task was 'bathing', followed by 'dressing' and 'toileting.' The final model found association with private NH (PR=1.33, p<0.001), age 83 and over (RP=1.26, p=0.003), reason for institutionalization “lack of caregiver” (RP=1.17, p=0.033) and osteoporosis (RP=1.23, p=0.045), adjusted by sex. The Study 2 is a 24-months longitudinal study with follow-up every 6 months (5 waves). Apart from the criteria considered in the Study 1, residents with FD for all BADL (bathing, personal hygiene, dressing, toileting, walking, transferring and eating) at baseline were excluded. The presence of functional decline was defined when there was a reduction the total score of BADL, which were assessed by a 5-point Likert scale. All independent variables of the Study 1 were considered, as well asthe mobility status, cognitive status (Pfeiffer test), toxic habits, physical activity and time-dependent variables. Statistical analysis was performed using the actuarial method, log-rank test, Cox univariate analysis and Cox regression. The cohort was composed of 280 individuals: 140, 50.0% (95% CI: 44.2-55.8%) experienced functional decline; 94, 33.6% (95% CI: 28.3-39.3%), maintained their functional capacity, and; 40, 14.3% (95% CI: 10.7-18.9%), showed functional improvement at one or more waves. The cumulative probability of functional maintenance was 44.0% (95% CI: 37.7-50.2%) at 24 months. The ability to eat showed the largest decline during the period (-0.54 points), followed by walking (-0.43), dressing (-0.35), transferring (-0.31), bathing (-0.29), personal hygiene (-0.24) and toileting (-0.22). The final model showed that the predictors factors of functional decline were severe cognitive impairment (HR=1.96, p=0.001), continence decline (HR=1.85, p=0.002) and incidence of hospitalizations (HR=1.62, p=0.020). |
