- W2075704805 abstract "Little is known about the evolution of functional status in dementia. Objective: To determine the hierarchical structure of activities of daily living (ADL) measured by four items (bathing, dressing, transferring and feeding) of the Katz scale in elderly subjects diagnosed with dementia. Incident cases of dementia in the Paquid Study and in the Three City Study (two prospective, population-based, long-term cohort studies) were analyzed. The hierarchical relationships between the four items were defined by i) restriction in bathing or dressing (level 1), ii) restriction in bathing or dressing and in transferring (level 2), iii) restriction in bathing or dressing and in transfer and in feeding (level 3). Guttman scale analysis was used to test hierarchical relationships and reproducibility and scalability were calculated. The evolution after the next follow-up, two to three years later was described. 808 cases of incident dementia were included, 6 participants were excluded because of missing data on the Katz scale. The hierarchical model fitted 99.3% of the subjects at baseline: 546 subjects (68.2%) were not ADL-restricted (level 0), 123 (15.3%) were restricted in bathing or dressing (level 1), 99 (12.3%) were restricted in level 2, and 28 (3.5%) were in level 3 (restricted in the 4 items). The Guttman analysis resulted in a scalogram of four items of Katz (coefficient of reproducibility = 99.5%, coefficient of scalability = 97.1%). Only 6 subjects were discordant (0.7%). After two to three years of follow-up, there was a significant trend towards increasing disability but mortality rate was high, particularly in the most severely disabled subjects (80.8% from level 3). The four items of the Katz's scale could be used as a hierarchical cumulative scale to summarize data and define disability profiles over time in elderly subjects with dementia." @default.
