Introduction of ultra-processed foods and associated factors among children under six months of age in the Southwest of the state of Bahia, Brazil

Abstract

The scope of this study was to assess the prevalence and associated factors with the introduction of ultra-processed food (UPF) among children under six months of age living in the southwest of Bahia state. This is an excerpt from a prospective cohort study conducted with pairs of mothers/babies. The introduction of UPF was defined by the intake of at least one UPF before the age of six months. Socioeconomic, maternal, paternal, gestational, and child-related information was gathered by the application of questionnaires. To analyze the factors associated with the outcome, Poisson regression was performed according to a hierarchical model. P-value<0.05 and 95% confidence interval are considered. A total of 300 mother/baby pairs were evaluated. Before 6 months, 31.3% of children have already received UPF. With greater introduction of cookies/biscuits (23.3%) and yogurt (14.3%). The introduction of UPF before six months of age was higher among families with lower income (p=0.038), lower maternal education (p=0.031), lower maternal (p=0.017) and paternal (p=0.013) age, among children who had cow’s milk <6 months (p<0.001) and tea <30 days (p=0.005). The results demonstrate the need for interventions aimed at reducing the introduction of UPF, especially for low-income families, with less education and among younger parents.
