Balanço de macronutrientes na dieta de idosos brasileiros: análises da Pesquisa Nacional de Alimentação 2008-2009

Estatuto do Idoso: análise dos fatores associados ao seu conhecimento pela população idosa brasileira

Resumo O objetivo deste artigo é analisar os fatores associados ao conhecimento do Estatuto do Idoso pela população brasileira não institucionalizada com 60 anos ou mais. Trata-se de um estudo transversal e exploratório, que utilizou dados do Estudo Longitudinal de Saúde dos Idosos Brasileiros (ELSI-Brasil) realizado nos anos de 2015 e 2016. A análise estatística foi feita por meio do teste qui-quadrado e emprego de modelos logísticos binários. Maiores chances de conhecer o Estatuto do Idoso entre os mais escolarizados (OR: 3,17; IC95%: 2,19-4,60), aqueles pertencentes ao quartil mais alto de riqueza (OR: 2,96; IC95%: 2,00-4,38) e entre os que sofreram discriminação em função da idade (OR: 1,73; IC95%: 1,39-2,16). Em contrapartida, ter 80 anos ou mais (OR: 0,59; IC95%: 0,43-0,82) e menor comunicação com os filhos (OR: 0,56; IC95%: 0,43-0,74) está associado a um menor conhecimento dessa legislação. Muitas desigualdades no conhecimento dessa legislação, em especial as socioeconômicas, foram observadas demonstrando que o conhecimento dos direitos estabelecidos não é homogêneo. O entendimento de toda a população quanto às prerrogativas do Estatuto do Idoso é essencial para avanços quanto a sua aplicabilidade e efetividade.

Agreement between two Meal Quality Indexes adapted to evaluate food consumption of institutionalized elderly

ABSTRACT Objective To assess agreement between two meal quality indexes adapted for elderly people, evidencing their similarities and differences Methods Agreement study with 322 institutionalized elderly individuals. Food consumption data were collected by the method of weighted food record, in two nonconsecutive days. The Meal Quality Index and the Main Meal Quality Index of each older adult were calculated for the lunch meal. Agreement between methods was tested by cross-classification in quartiles and weighted kappa (Kw), and the difference between medians by the Wilcoxon test. Results The Meal Quality Index median was 54.67 points and the Main Meal Quality Index 53.51 points (p=0.723). When the components of each index were assessed, those associated to the consumption of carbohydrates, total fat and saturated fat were similar. The consumption of fruits separated from vegetables in the Main MealQuality Index evidenced low consumption of vegetables by the elderly. Cross-classification by quartiles showed good agreement; the exact one being 48.8% and the disagreement 3.4% (Kw=0,447). The proportion of elderlyindividuals in the same exact or adjacent quartile was greater than 85.0%. Agreement was higher in males (89.4%, Kw=0.475); in the age range of 70 to 79 years (91.1%; Kw=0.562) and in non-profit nursing homes(96.7%; Kw=0.622). Conclusion The two indexes reviewed show a good agreement between them and common characteristics. The number of components is higher in the MMQI and may represent a more detailed assessment of meal quality.

Usual energy and macronutrient intakes in a large sample of Iranian middle-aged and elderly populations

AIM

The present study aimed to assess the usual distribution of energy and macronutrient intake among a large representative sample of Iranian healthy middle-aged and elderly people.

METHODS

In this cross-sectional study, a second follow-up survey of the Isfahan Cohort Study (ICS) was carried out; 1922 people aged 40 years and older were investigated. Dietary intakes were collected using 24-hour recall and two or more consecutive food records. Distribution of energy and macronutrient intake was estimated using traditional and National Cancer Institute (NCI) methods.

RESULTS

The mean usual intake of energy was 1749.2 kcal based on the NCI method. Carbohydrate constituted 59.98% and protein 17.42% of total energy intake. The mean contributions of total fat, saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFAs) to energy intake were 25.74%, 9.5%, 4.92 and 7.75%, respectively. Approximately 7% of studied females aged 51-70 years met the recommended or higher levels for fibre. Females had significantly higher compliance of the recommended cholesterol level than males (age range of 40-70 years; P < 0.0001).

CONCLUSIONS

It appears that Iranian middle-aged and elderly people are advancing towards a high risk of obesity and non-communicable chronic diseases. Nutritional interventions for improving the diet amongst this at-risk population are necessary.
