Fatores associados ao padrão de consumo alimentar da população brasileira urbana

Abstract

This study evaluated factors associated with dietary patterns in the Brazilian population based on the Living Standards Survey conducted in the Northeast and Southeast regions of the country. Multi-stage probability sampling was employed to select the households, and for the present analysis 5,121 adults aged 20 to 50 years were included. Pregnant women and individuals reporting chronic health conditions were excluded. Through principal component analysis, two major family dietary patterns were identified: a mixed pattern, in which all groups and foods have approximately the same factor loading, and a second pattern based main1y on rice and beans, which was called a traditional diet. Weight and height were measured in the households, and food intake was based on a 21-item semi-quantitative family questionnaire. The Northeast (as compared to the Southeast) was negatively associated with the mixed pattern. Body mass index was positively associated with the mixed pattern, whereas leisure physical activity and Black skin color were negatively associated with the mixed pattern. Schooling and income levels explained most of the dietary variance, but after adjusting for education and income, region of residence remained significantly associated and was the third most important explanatory variable.

Identification of food intake patterns and associated factors in teenagers

“…For Sichieri et al 8 , the factors income and education level better explain the dietary patterns seen in the Brazilian Northeast and Southeast. Studies conducted in Pelotas (RS) indicate a higher frequency of poor dietary habits among adolescents of higher-income families.…”

“…However, their results indicate that the relationship between socioeconomic factors and dietary patterns is controversial and varies among populations, suggesting the pertinence of investigating these relationships in other contexts and different population groups 8,9 .…”

“…Knowing the effects of dietary patterns on disease promotion and prevention and understanding their relationship with socioeconomic factors are important aspects for developing intervention programs and healthpromoting measures 8,16 . Hence, the objective of this study is to identify the dietary patterns of adolescents attending the public schools of Salvador (BA) and determine the demographic, social, and economic factors associated with each dietary pattern.…”

Avaliação dos marcadores de consumo alimentar do VIGITEL (2007-2009)

“…As to the second approach, cluster analysis (in groups) 10,11 and factorial analysis, or principal components analysis [12][13][14] , have been more frequently reported in literature. The main difference among them is that the cluster analysis gathers individuals, while the factorial analysis gathers variables.…”

Characterization of pre-gelatinized rice and bean flour

“…Rice (Oryza sativa L.) and common beans (Phaseolus vulgaris L.) is a staple food of large part of the world's population, especially in Brazil, where they are the basis of daily meals and the major source of proteins to low-income populations (SICHIERI; CASTRO;MOURA, 2003). Some studies have reported that rice and beans provide high biological quality and high protein digestibility (around 80%), and when ingested together they supply essential amino acids thus being characterized as complementary food (SICHIERI, 2002;TEBA;ASCHERI;CARVALHO, 2009).…”
