Ingestão inadequada de nutrientes na população de idosos do Brasil: Inquérito Nacional de Alimentação 2008-2009

Abstract

OBJECTIVE:To estimate the prevalence of inadequate nutrient intake in the Brazilian elderly. METHODS:This study was based on data from the National Dietary Survey, part of the Household Budget Survey 2008-2009. All individuals aged 60 and over, totaling 4,322 individuals, were included. Individual food intake was obtained from food records from two non-consecutive days. The habitual intake for each nutrient was estimated by the National Cancer Institute method, in which sex and region were included as covariates. The prevalence of inadequate nutrient intake was estimated stratifi ed by sex and region using the EAR method to defi ne cut-off points. RESULTS:A high prevalence of inadequate intake (> 50%) of vitamins E, D and A, calcium, magnesium and pyridoxine was observed for both sexes. In all regions, 100% inadequate vitamin E intake was observed. Vitamin D showed almost 100% inadequate intake except in the North region. The prevalence of inadequate vitamin A intake was higher than 70% in the North, Northeast, and Midwest regions. Among the minerals evaluated, calcium and magnesium showed the highest prevalence of inadequate intake (> 80%) in all regions. CONCLUSIONS:The present study found a high prevalence of inadequate intake of nutrients recognized as being protective against chronic diseases among the Brazilian elderly.

Dairy products consumption in Brazil is associated with socioeconomic and demographic factors: Results from the National Dietary Survey 2008-2009

“…In the specific cases of vitamins A, C, D and E and calcium, inadequate intake surpasses the levels of 65%, 30%, 98%, 99% and 84%, respectively [1][2][3] . A recent change in feeding habits could help explain these findings.…”

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

“…A study with the same population revealed an alarming situation: the high prevalence of inadequacy (more than 50% of calcium, magnesium, and vitamins A, D, E, and pyridoxine, worse (more than 70%) in the north, northeast, and center-west regions 13 . This scenario can be associated with a food pattern characterized by the inadequate intake of milk and derivatives, fruits, vegetables, and whole grains.…”

“…Regardless of gender, the household status, and the region, the mean value observed was of approximately 20%, being in agreement with the recommendations from the Institute of Medicine 18 . This observation can be justified by the dietary habits of the Brazilians, whose diet is based on the intake of meats, rice, and beans, considered as sources of protein 13 . Among the elderly, the adaptation of protein intake is essential to prevent diseases such as sarcopenia and osteoporosis 22 .…”

“…In the end, 13,569 households answered the survey, resulting in the data of 34,032 individuals, out of whom 4,322 were 60 years old or older. More details about the study population are available in the manuscript by Fisberg et al 13 .…”
