ABSTRACT
OBJECTIVE
Assessing the regular consumption of ultra-processed foods by children at 24 months of age from the 2015 Pelotas Birth Cohort and the main demographic, socioeconomic, and behavioral factors related to the consumption of these products.
METHODS
Population-based cohort in the city of Pelotas, RS, where 4,275 children were assessed at birth and 95.4% of them were followed up until 24 months of age. Food consumption was assessed by a questionnaire on regular consumption of ultra-processed foods, which collected information regarding sex, household income, maternal skin color, schooling level, and age, the child attending day care and having siblings, breastfeeding status, and obesity. The outcome was the sum of ultra-processed foods regularly consumed by a child. A multivariate Poisson regression analysis was used to calculate the association between the regular consumption of ultra-processed foods and exposure variables.
RESULTS
The mean number of ultra-processed foods consumed was 4.8 (SD = 2.3). The regular consumption of ultra-processed foods was positively associated with black skin color and having siblings, and negatively associated with household income and maternal schooling level and age.
CONCLUSION
The mean regular consumption of ultra-processed foods by children from the 2015 Pelotas Birth Cohort is high, which can negatively affect the children’s diet. The risk of consuming this kind of food was higher among children from families of lower socioeconomic status, whose mothers present lower education level, black skin color, and younger age.
