Ultra‐processed food consumption in children from a Basic Health Unit

Abstract

ObjectivesTo evaluate the contribution of ultra‐processed food (UPF) on the dietary consumption of children treated at a Basic Health Unit and the associated factors. MethodCross‐sectional study carried out with a convenience sample of 204 children, aged 2–10 years old, in Southern Brazil. Children's food intake was assessed using a 24‐h recall questionnaire. Food items were classified as minimally processed, processed for culinary use, and ultra‐processed. A semi‐structured questionnaire was applied to collect socio‐demographic and anthropometric variables. Overweight in children was classified using a Z score >2 for children younger than 5 and Z score >+1 for those aged between 5 and 10 years, using the body mass index for age. ResultsOverweight frequency was 34% (95% CI: 28–41%). Mean energy consumption was 1672.3kcal/day, with 47% (95% CI: 45–49%) coming from ultra‐processed food. In the multiple linear regression model, maternal education (r=0.23; p=0.001) and child age (r=0.40; p<0.001) were factors associated with a greater percentage of UPF in the diet (r=0.42; p<0.001). Additionally, a statistically significant trend for higher UPF consumption was observed when data were stratified by child age and maternal educational level (p<0.001). ConclusionsThe contribution of UPF is significant in children's diets and age appears to be an important factor for the consumption of such products.
