Objective: To compare the performance of elderly people with different levels of severity of dementia using questionnaires on basic activities of daily living (BADLs) and instrumental activities of daily living (IADLs). Also, to verify whether there were any association between the IADL questionnaires applied. Method: Ninety elderly people, aged 75.46 ± 7.66 years with a clinical diagnosis of dementia (DSM-IV/APA) who were seen at the Minas Gerais Reference Center for the Elderly, were randomized selected and classified according to the level of severity of their dementia (Clinical Dementia Rating). Their BADLs were assessed using the Katz Index and their IADLs by the Lawton-Brody and Pfeffer indexes. The Kruskal-Wallis and Mann-Whitney tests were used in order to investigate the elderly people's performance regarding BADLs, while the Spearman correlation was used to investigate the relationships among the IADL (α< 0.05). Results: Statistically significant differences in performance were found between the elderly people with different levels of severity of dementia, as assessed by the BADL and IADL questionnaires (p< 0.001). The IADL questionnaires presented significant correlation for the total sample (p< 0.0001; r = -0.818) as well as for the groups with mild dementia (p= 0.007; r = -0.530) and severe dementia (p< 0.0001; r = -0.723). Conclusion: The severity of the dementia process interfered with the elderly people's performance of the elderly in BADLs and IADLs. The IADLs were more affected in the early stages of dementia whereas the BADLs were more affected in the more advanced stages. Despite structural particularities, the IADL questionnaires utilized seemed to be measuring a common construct. The variability in the clinical condition of the individuals with moderate dementia may be an explanation for the lack of correlation between the questionnaires in this specific group.

ResumoO objetivo do estudo foi verificar a prevalência da síndrome de fragilidade e sua relação com a capacidade e o desempenho funcional em idosos frequentadores de grupos de convivência. O perfil de fragilidade foi determinado por meio dos critérios perda de peso não intencional; exaustão; baixa velocidade de marcha; baixa força de preensão manual e baixo consumo calórico. A capacidade funcional foi avaliada pelo Timed Up and Go (TUG) e o desempenho funcional, pelo índice de Lawton. O perfil de fragilidade foi apresentado em frequências e a associação foi analisada pelo teste de correlação de Spearman (α = 5%). Participaram 117 idosos (70,1 ± 7,3 anos). A maioria foi classificada como pré-frágil (51,3%). A média do TUG para os não-frágeis (NF) foi 11,3 s (± 1,9), pré-frágeis (PF) 12,7 s (± 3,4) e frágeis (FF) 16,7 s (± 3,3). O escore médio do Lawton em NF foi 29,8 (± 0,6), PF 28,4 (± 3,3) e FF 27,4 (± 2,8). Houve associação das classes de fragilidade com a capacidade e o desempenho funcional (p= 0,001). Houve maior prevalência de idosos pré-frágeis na amostra pesquisada, e idosos frágeis e pré-frágeis apresentaram piores desempenhos nos testes funcionais. Esses resultados reforçam o pressuposto de que a fragilidade compromete a funcionalidade em idosos. AbstractThe aim was to evaluate the correlation between the frailty phenotype and capacity and functional performance in elders attending conviviality groups. The frailty phenotype was identified with the weight loss; decrease of gait speed; decrease of physical activity; decrease of manual force and exhaustion. The functional capacity was measured by Timed Up and Go (TUG) and functional performance by the Lawton index. The frailty profile was presented in frequencies and the association was assessed by Spearman correlation test (α = 5%). A hundred and seventeen elders participated of this study (70±7.3 yrs). Most participants were classified as pre-frail (51.3%). The mean of the

Introduction: Accurate measures of physical activity to establish dose-response relationship in health outcomes are still controversial. Scales that estimate caloric expenditure are proposed with a view to categorizing the phenomenon globally. Objective: To carry out a factor analysis of the structure of the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese, and propose a new adapted version for the Brazilian elderly community. Methods: Participants were elderly female members of the community, without any distinction in terms of ethnic group and/or social class, who frequented extension projects of two higher education institutions. Those with cognitive impairments; dependence on walking aids; musculoskeletal pain in the last two weeks and neurological diseases were excluded from the study. All participants answered the questionnaire with sociodemographic and clinical data and the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese version. We determined whether each activity had been undertaken by the participants and the average number of times it was performed over the last two weeks, considering average time, in minutes, on each occasion. Each activity was considered a single item and energy expenditure was calculated according to the authors’ instructions. We used factor analysis with Varimax orthogonal rotation, excluding items whose variance was equal to zero. Correlation between items was determined using the Pearson correlation matrix. Internal consistency between items, before and after the factor analysis, was verified using Cronbach’s α coefficient. 5% significance level. Results: Participants were 220 women (70.8 ± 5.9 years). The factor analysis resulted in 10 components, which explained, in total, 61.87% of the variance of the total score on the scale. Each component was composed of one, two or three aggregate items. Internal consistency by Cronbach’s α coefficient was 0.30. Conclusion: The factor analysis of the structure of the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese- has shown a new range with 10 components, which explained, in total, more than 60% of the variance of the total score on the scale, yet with low internal consistency. Level of Evidence III; Study of nonconsecutive patients; without consistently applied reference ‘‘gold’’ standard.

O objetivo deste trabalho foi adaptar transculturalmente o instrumento Southampton Assessment of Mobility e testar sua confiabilidade intra e interexaminadores para idosos brasileiros da comunidade, com demência, classificados quanto à gravidade pelo Clinical Dementia Rating. O instrumento adaptado foi aplicado em uma amostra de 107 idosos (76,26 anos ± 7,59; 27,1% homens, 72,9% mulheres) com diagnóstico clínico de demência dado pelo serviço de geriatria do Centro de Referência em Atenção ao Idoso Professor Caio Benjamin Dias, do Estado de Minas Gerais, Hospital das Clínicas, Universidade Federal de Minas Gerais, Minas Gerais, Brasil. Dentre os avaliados, 39 (76,85 anos ± 7,75; 23,1% homens, 76,9% mulheres) foram aleatorizados para avaliação da confiabilidade. A ferramenta estatística foi o teste kappa. Os resultados mostraram que a confiabilidade intra e interexaminadores foram, respectivamente: demência leve 0,89-0,86; moderada 0,79-0,85 e grave 0,53-0,49. O instrumento adaptado demonstrou ser aplicável à população alvo e demonstrou ter confiabilidade "quase perfeita" para demência leve e moderada. Para a demência grave os índices de confiabilidade foram "moderados".
