          Abstract

          OBJETIVO: Descrever o valor energético total e contribuição percentual de calorias por macronutrientes da alimentação de idosos domiciliados em Fortaleza/CE. MÉTODOS: Este estudo é populacional, transversal e domiciliar. Participaram deste estudo 458 idosos (66,6% mulheres). As variáveis avaliadas foram: valor energético total (VET) da alimentação e contribuição percentual de calorias por proteínas, carboidratos e lipídios. Os resultados são apresentados sob a forma de médias, desvios-padrão e distribuição percentilar (P5, P10, P25, P50, P75, P90, P95). Os testes t-Student e análise de variância (ANOVA de uma via) com o teste Post Hoc LSD foram utilizados para verificar a diferença estatística das médias entre dois grupos e entre três grupos ou mais, respectivamente. RESULTADOS: Ao comparar os valores médios do VET entre as categorias das variáveis socioeconômico-demográficas foi encontrada diferença estatisticamente significativa entre as mulheres para cor, anos de estudo e nível socioeconômico. Entre os homens foram encontradas diferenças para anos de estudo e nível socioeconômico. O valor energético médio da alimentação dos homens foi significativamente superior ao das mulheres. Entre as mulheres o valor médio foi 1.236,4 kcal e entre os homens foi 1.475,8 kcal. Os valores médios da contribuição percentual de calorias por proteínas, carboidratos e lipídios foram semelhantes entre homens e mulheres. CONCLUSÃO: Os idosos deste estudo apresentam diferenças significativas nas médias do valor energético da alimentação entre os sexos e entre as categorias de anos de estudo e nível socioeconómico. As mulheres apresentaram, ainda, diferenças significativas entre as categorias de cor. A contribuição relativa média dos macronutrientes no valor energético da alimentação foi semelhante entre os sexos e grupos etários.

          OBJECTIVE: Describe the total energy value and percentage contribution of calories from macronutrients in the diet of elderly individuals living in Fortaleza/CE. METHODS: This is a population-based, cross-sectional domiciliary study, which included 458 elderly individuals (66.6% women). The variables evaluated were total energy value (TEV) and the percentage contribution of calories from proteins, carbohydrates, and lipids. The results are shown as mean, standard deviation, and percentile distribution (P5, P10, P25, P50, P75, P90, P95). The Student's t-test and analysis of variance (one-way ANOVA) with LSD post-hoc tests were used to determine the statistical significance of means between two groups and among three or more groups, respectively. RESULTS: When comparing the mean values of TEV among categories of socioeconomic and demographic variables, statistically significant differences were found between women for ethnicity, years of schooling and socioeconomic level. Among men, differences were found for years of schooling and socioeconomic level. The mean energy value of men's diet was significantly higher than that of women (1475.8 kcal and 1236.4 kcal, respectively). The mean values of calorie percentage contribution from proteins, carbohydrates, and lipids were similar between men and women. CONCLUSION: The elderly of this study showed significant differences in mean values of TEV between sexes and between the categories years of schooling and socioeconomic level. Women also showed significant differences between the ethnic categories. The mean relative contribution of macronutrients in TEV was similar between genders and age groups.

            Inadequate nutrient intakes are common and are associated with low diet variety in rural, community-dwelling elderly.

            Poor dietary habits and inadequate nutrient intakes are of concern in the elderly. The nutritional characteristics of those who survive to become the oldest are not well defined. Our goal was to describe dietary habits, nutrient intakes and nutritional risk of community-dwelling, rural Iowans, 79 y of age and older. Subjects were interviewed (n = 420) using a standardized format on one occasion in their homes and instructed to complete 3-d diet records (n = 261) after the in-home interview. Standardized interviews assessed demographic information, cognitive function and dietary habits (Nutrition Screening Initiative Checklist). Adequate nutrient intake was defined as consumption of the nutrient's estimated average requirement, 67% adequate intake or 67% recommended dietary allowance. Mean age was 85.2 y, 57% lived alone and 58% were widowed. Subjects completing 3-d diet records were younger, more cognitively intact and less likely to be at nutritional risk than subjects not completing diet records. The percentage of subjects with inadequate intakes of selected nutrients was 75% for folate, 83% for vitamin D and 63% for calcium. Eighty percent of subjects reported inadequate intakes of four or more nutrients. Diet variety was positively associated with the number of nutrients consumed at adequate intakes (r = 0.498), total energy (r = 0.522) and dietary fiber (r = 0.421). Our results suggest that rural, community-dwelling old have inadequate intakes of several nutrients. Recommendations to increase diet variety and consume a nutrient supplement may be necessary for elderly people to achieve adequate nutrient intakes.

              Energy and nutrient intake of young-old, old-old and very-old elderly in Germany.

              Reliable information about the nutritional status of elderly people in Germany is lacking. To describe energy and nutrient intake of elderly people living in private households in Germany with special focus on age-related differences in the elderly. Descriptive nationwide cross-sectional study. Germany, 1998. : A random sample of 4020 elderly men and women living independently in private households stratified in three age groups (65-74, 75-84, 85+ y), of which 1550 participated and 1372 (789 female subjects) provided reliable 3-day estimated dietary records. The median daily energy intake was 2207 kcal (9.2 MJ) in men and 1994 kcal (8.3 MJ) in women without difference between the age groups. Protein intake amounted to 91 and 81 g/day, respectively, corresponding to 1.2 g/kg body weight per day. The median intake was well above the recommended amount for all nutrients except dietary fibre, calcium, vitamin D and folate, where 38, 35, 75 and 37% did not reach two-thirds of the recommended amount. An age-related decline was observed for calcium intake in male and for dietary fibre, water, calcium, magnesium, iron, vitamins A, E, C and thiamin intake in female participants; however, the overall picture was unaffected by these differences. Dietary intake in these independently living elderly, including the very-old, is adequate for most of the evaluated nutrients. Increased intake of foods rich in dietary fibre, calcium, vitamin D and folate as well as regular sunlight exposure is recommended in order to optimize nutrient supply in this population group.
