How to evaluate ultra-processed food intake in pediatrics? UPF score: an easy alternative

Résumé fourni par la source

BACKGROUND: The rising intake of ultra-processed foods (UPFs) among the pediatric population poses challenges due to the lack of precise and easily accessible tools to quantify such intake. This complicates understanding its effects on dietary quality and hampers the design of interventions to prevent the negative impact of UPF consumption on health. Given these challenges, it is essential to establish reliable methods to assess UPF consumption and its effect on diet. OBJECTIVE: This study aims to determine the relationship between the UPF score and dietary characteristics. METHODS: This cross-sectional study involved 353 participants aged 3 to 17. The methods included (1) collection of a three-day food record; (2) an evaluation of intake across five food groups; (3) categorization of intake frequency (0, 1, 2, or up to 3 times weekly); and (4) scoring by cumulative intake. Principal component analysis and regression models were utilized to assess diet associations with UPF score. RESULTS: Higher cumulative UPF score groups were associated with increased intake of energy, fats, and sodium (p < 0.01); decreased fiber intake (p = 0.03), vegetables, fruits, and cereals (p < 0.05); higher sugar intake (p < 0.01); and reduced intake of vitamins A and C (p < 0.05). Four principal components, representing over 65% of sample variability, identified two healthy and two less healthy dietary patterns. Linear regression indicated higher fiber intake at lower UPF scores, declining with higher UPF scores. CONCLUSIONS: The UPF score represents a useful tool for assessing UPF intake and dietary characteristics in pediatric populations.
