| Abstract | |
The study aimed to analyze the household availability of energy, nutrients and carotenoids to Brazilian families living in rural and urban areas, the Major Geographic Regions, as well as the nutritional status of adults belonging to this population. The individual information from the Household Budget Survey (POF 2008-2009) from the Brazilian Institute of Geography and Statistics (IBGE) were used as a database. We adopted a preliminary database created from the POF microdata from 2002 to 2003. This revised and updated spreadsheet generated a new database. The values recommended by the Institute of Medicine (1997, 1998, 2000, 2001, 2002, 2004) were used as a parameter to assess the participation of macronutrients in total energy (VET) and availability of vitamins and minerals. The identification and content of carotenoids was based on the information contained in the table Nutrient Database for Standard Reference Release 23 - United States Department of Agriculture (USDA). The average daily availability of energy and nutrients and nutritional status were calculated using the Statistical Analysis System - SAS. The results show differences in the availability of energy and nutrients to Brazilian families, broken down by Major Regions and geographic areas (rural and urban). Regarding the availability of energy, the highest contents were identified for families in rural areas. The energy distribution of macronutrients in the VET revealed significant contribution of carbohydrates to the total of Brazilian families living in rural areas. In rural and urban households of Major Regions, the contribution of macronutrients to the VET proved in accordance with the recommended values. With respect to vitamin C, vitamin B6, vitamin B12, folate, and pantothenic acid, the results indicated lower availability of the recommendations. The mean content observed for vitamins A, B1 and B2 met the benchmarks for all families. With regard to minerals, the availability of calcium, magnesium, zinc, potassium and iron proved to be reduced in most Brazilian households. The mean values observed for the minerals sodium and manganese exceeded the recommendations for all families. The availability of carotenoids showed a significant increase in the 2008-2009 survey, when compared with the values of POF 2002-2003, although it continues to be unsatisfactory in Brazilian households. A prevalence of overweightness (32,9%) and obesity (12,5%) was detected among adults. It is emphasized that the results refer to estimates of quantities of food purchased for consumption at home, so they can involve some degree of underestimation. The results obtained in this study show significant differences in the availability of energy and nutrients to Brazilian families. Greater availability of carotenoids was observed in households in the South, especially for families living in rural areas. Overweight and obesity stood out among adults. (AU) | |
