Ultraprocessed food intake and body mass index change among youths: a prospective cohort study.

ABSTRACT:

Background

Suboptimal diets may promote undesired weight gain in youths, with high ultraprocessed food (UPF) intake becoming a significant concern in the United States.

Objectives

We evaluated the association between UPF intake and body mass index [BMI (in kg/m²)] change in large United States youth cohorts.

Methods

Participants included children and adolescents (7-17 y) from the Growing Up Today Study (GUTS1 and GUTS2) who completed baseline and ≥1 follow-up diet and anthropometrics assessment (GUTS1 1996-2001: N = 15,797; GUTS2 2004-2011: N = 9720). Follow-up years were based on diet assessment availability. UPFs were categorized using the Nova system, with intakes evaluated as the cumulative mean percent energy from UPFs and subgroups. BMI was assessed u
