This study focused on the association between dietary patterns and socio-demographic and lifestyle factors. A population-based cross-sectional study was performed in 1,026 adult women from Southern Brazil. Dietary patterns were identified using principal components analysis. In the multivariable analysis, a Poisson regression model was used to estimate the prevalence ratio and 95%CI. Wealthier women were more likely to follow healthy diets. A Low Cost Healthy Diet was more prevalent among women with a partner, and a High Cost Healthy Diet was more prevalent among women not currently working and who exercised regularly. Women with lower education levels were less likely to follow a Low Cost Healthy Diet, but more likely to follow the Higher-Risk Low Cost Diet. The Low Cost Higher-Risk Diet was more prevalent among women with a lower income. Low and medium cost healthy diets were positively associated with age. The results showed that women's dietary choices are influenced by socioeconomic factors and are not only dependent on food prices.

RESULTADOS:O índice de confiança da análise fatorial foi verificado por meio do determinante da matriz de correlação (6,28 -4 ), da medida de adequação amostral (KaiserMeyer-Olkin=0,823) e do teste de esfericidade de Bartlett (χ² (1225) =7406,39; p<0,001), todos com resultados satisfatórios, garantindo o uso desta ferramenta. Foi possível identificar cinco padrões alimentares, com 10 alimentos cada um, denominados de: padrão alimentar saudável custo 1, padrão alimentar saudável custo 2, padrão alimentar saudável custo 3, padrão alimentar de risco custo 1 e padrão alimentar de risco custo 3. CONCLUSÕES:Foi possível identificar cinco padrões alimentares nas mulheres adultas estudadas, com diferenças de custos entre eles. Esses resultados sugerem que o custo pode ser um dos determinantes da escolha e consumo dos alimentos. ABSTRACT OBJECTIVE: To explore the dietary patterns of adult women and to provide information for validating the instrument used. METHODS:A population-based cross-sectional study was carried out in a representative sampling of 1,026 women aged 20 to 60 years living in Southeastern Brazil, in 2003. A 70-item food frequency questionnaire was used to measure food intake. Dietary patterns were identified using principal component analysis. RESULTS:The reliability of factor analysis was assessed through the KaiserMeyer-Olkin statistic, that was equal to 0.823, the Bartlett test of sphericity, which

A motivação na perspectiva da Teoria da Autodeterminação (TAD) sugere que uma pessoa pode ser motivada em diferentes níveis. Neste estudo essas diferenças são exploradas através de comparações dos níveis gerais de motivação, observando-se as variáveis "sexo e faixa etária". Uma amostra de 635 praticantes de ambos os sexos e com idades variando de 18 a 55 anos respondeu o "Inventário de Motivação à Prática Regular de Atividade Física e Esportiva" (IMPRAFE-126). Os resultados indicam haver diferença significativa (F(2, 632) = 7,214; p = 0,001) somente quando controlada a faixa etária. As diferenças foram interpretadas conforme preconiza a TAD e com relação aos estados e tarefas do desenvolvimento.

Objective:To analyze the evidences of construct validity of the Katz Index for the retrospective assessment of activities of daily living (ADL) by informants, to assist neuropathological studies in the elderly. Method: A cross-sectional study analyzed the functional ability of ADL measure by the Katz Index, of 650 cases randomly selected from the Brazilian Brain Bank of the Ageing Brain Study Group (BBBABSG) database. Sample was divided in two subsamples for the analysis (N=325, each) and then stratified according to cognitive decline assessed by the Clinical Dementia Rating Scale (CDR). Factor analyses with calculations of internal consistency and invariance were performed. Results: Factor analysis evidenced a unidimensional instrument with optimal internal consistency, in all subgroups. Goodness of fit indices were obtained after two treatments of covariance, indicating adequacy of the scale for assessing ADL by informants. The scale is invariant to cognitive decline meaning that it can be used for subjects with or without cognitive impairment. Conclusion: Katz Index is valid for the retrospective assessment of basic ADL by informants, with optimal reliability.
