Fatores de risco para mortalidade em idosos

OBJECTIVE: The risk factors for diseases and premature deaths are important in drawing up preventive measures. This study had the aim of analyzing the risk factors for death among elderly people. METHODS: This study was carried out among participants in the SABE (Health, Wellbeing and Aging) study, in the city of São Paulo in 2000. Interviews were conducted with 2,143 elderly people (60 years old or over), using a standardized questionnaire for the SABE study. The sample was obtained from census tracts, in two stages, with replacements and with probability proportional to the population, and with supplementation of the sample of people aged 75 years or over. The final data were weighted so that they could be expanded. Between the two data collection times, there were 38 deaths which comprised study sample. Logistic regression was utilized for the data analysis, with a significance level of 5%. RESULTS: The risk factors found were: locomotion difficulty, advanced age, male gender, self-assessment of health as "bad" and difficulty in going to the bathroom, OR=3.15; 2.93; 2.90; 2.69 and 2.51, respectively. CONCLUSIONS: The results may contribute towards the adoption of preventive measures for elderly people, with the aim of diminishing the expected number of fatal outcomes.OBJETIVO: Os fatores de risco para as doenças e mortes prematuras são importantes para a elaboração de condutas preventivas. O objetivo do trabalho foi analisar os fatores de risco para óbito entre idosos. MÉTODOS: O estudo foi realizado no Município de São Paulo, em participantes do estudo SABE (Saúde, Bem-estar e Envelhecimento), em 2000. Foram entrevistados 2.143 indivíduos com 60 anos ou mais, utilizando-se o questionário padronizado do estudo SABE. A amostra foi obtida de setores censitários em dois estágios, com reposição e com probabilidade proporcional à população, com complementação da amostra de pessoas de 75 anos ou mais. Os dados finais foram ponderados para poderem ser expandidos. Entre os dois períodos de coleta de dados ocorreram 38 óbitos que compuseram a amostra do estudo. Para a análise dos dados, utilizou-se regressão logística, com nível de significância de 5%. RESULTADOS: Os fatores de risco encontrados foram: dificuldade de locomoção, idade avançada, gênero masculino, auto-avaliação de saúde como "má" e dificuldade para ir ao banheiro, OR=3,15; 2,93; 2,90; 2,69 e 2,51, respectivamente. CONCLUSÕES: Os resultados podem contribuir para a adoção de medidas preventivas para os idosos, visando à diminuição de desfechos fatais antecipados

Antioxidant intake among Brazilian adults - The Brazilian Osteoporosis Study (BRAZOS): a cross-sectional study

<p>Abstract</p> <p>Background</p> <p>Antioxidant nutrient intake and the lesser formation of free radicals seem to contribute to chronic diseases. The aim of the present study was to evaluate the intake profile of the main dietary antioxidants in a representative sample of the adult Brazilian population and discuss the main consequences of a low intake of these micronutrients on overall health.</p> <p>Methods</p> <p>The sample comprised 2344 individuals aged 40 years or older from 150 cities and was based on a probabilistic sample from official data. The research was conducted through in-home interviews administered by a team trained for this purpose. Dietary intake information was obtained through 24-h recall. The Nutrition Data System for Research software program was used to analyze data on the intake of vitamins A, C and E, selenium and zinc, which was compared to Dietary Reference Intakes (DRIs). Differences in intake according to sex, anthropometrics, socioeconomic status and region were also evaluated. The SPSS statistical package (version 13) was used for the statistical analysis. P-values < 0.05 were considered significant.</p> <p>Results</p> <p>Higher proportions of low intake in relation to recommended values were found for vitamin E (99.7%), vitamin A (92.4%) and vitamin C (85.1%) in both genders. Intake variations were found between different regions, which may reflect cultural habits.</p> <p>Conclusion</p> <p>These results should lead to the development of public health policies that encourage educational strategies for improving the intake of micronutrients, which are essential to overall health and prevention of non-communicable diseases.</p
