Characteristics associated with dietary patterns in Brazilian children under two years of age

OBJECTIVE: To analyze the dietary patterns of Brazilian children under two years of age and assess their association with sociodemographic characteristics and health service use. METHODS: This is a cross-sectional study with data from the 2013 National Health Survey (PNS). Patterns were found for two age groups by principal component analysis and their correlation with characteristics of interest was tested by linear regression models. RESULTS: We found two dietary patterns for our groups. The first consisted of the consumption of fresh or minimally processed foods and the second, of ultra-processed foods. The greater adherence of children between six and 11 months to the first pattern was associated with higher per capita family income and urban residences in the most developed regions of Brazil. At 12 months or more, adherence related to white race/color, higher per capita family incomes, residence in more developed regions, and visits to private childcare. Adherence to the second pattern among children under one year of age was inversely associated with Yellow or Indigenous race/color, residence in the Brazilian Northeast, and childcare in specialized public or private services. At 12 months or more, greater adherence was directly associated with Black or Brown children who resided in more developed regions, and inversely associated with those living in the Brazilian Northeast. CONCLUSION: We found two opposite dietary patterns in Brazilian children under two years of age and that several social determinants modify their chance of adhering to these patterns.
