title: Familial aggregation and dietary patterns in the Brazilian population.
abstract: The aim of the study was to identify dietary patterns in Brazil and verify aggregation among members of the same family based on the Brazilian National Dietary Survey, a nationwide dietary survey conducted in 2008-2009 in individuals over 10 years of age. Dietary intake was estimated with a food record. Dietary patterns were identified by factor analysis, and familial aggregation was verified by linear regression. Three major dietary patterns were identified: (1) a traditional snack featuring coffee, rolls, oils and fats, and cheese; (2) traditional main meal, based on rice, beans and other legumes, and meat; and (3) fast food type snacks, namely sandwiches, processed meats, soft drinks, snacks, and pizza. Pattern 2 showed the strongest association (β = 0.37-0.64). Patterns 1 and 3 showed positive associations for all pairs of family members, with β ranging from 0.27 to 0.44 and 0.32 to 0.42, respectively. The study showed familial aggregation of dietary patterns in the Brazilian population.
