Factors Correlated With Ultra-Processed Food (UPF) Intake in Preschool-Aged Children and Association With Weight

Understand the correlates of ultra-processed food (UPF) intake and examine the association of UPF on body mass index in children aged 3–5 years. Secondary analysis of a prospective cohort of 3–5-year-olds/parent, followed 1-year between March 2014 and October 2016. Usual UPF intake from 2 3-day food records completed 1 year apart, a standardized nutrient database customized with child-specific foods, and a NOVA food classification system was used. Child/parent characteristics and media use were measured via parent-reported surveys. Child weight/height objectively measured. New Hampshire community. Six hundred and sixty-seven parent-child dyads were screened, and 624 were enrolled with 90% follow-up. Primary outcome: identify correlates of UPF intake. Secondary outcome: determine if UPF intake is associated with body mass index change. Adjusted β linear regression, linear regression, P
