    Abstract:
    OBJECTIVE: 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. DESIGN: 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. SETTING: New Hampshire community. PARTICIPANTS: Six hundred and sixty-seven parent-child dyads were screened, and 624 were enrolled with 90% follow-up. MAIN OUTCOME MEASURE(S): Primary outcome: identify correlates of UPF intake. SECONDARY OUTCOME: determine if UPF intake is associated with body mass index change. ANALYSIS: Adjusted β linear regression, linear regression, P <0.05. RESULTS: Ultra-processed food accounted for 67.6% of total caloric intake. In adjusted models, children's UPF intake was positively associated with increasing child age, greater hours watching television, and more frequent parent soda/fast-food intake. Ultra-processed food intake was negatively associated with higher parent education and reported race/ethnicity other than non-Hispanic White. There was no association between UPF intake and weight. CONCLUSIONS AND IMPLICATIONS: There are several predictors of UPF intake in young children. Family-level interventions could be implemented to encourage the intake of minimally processed foods before and during preschool years.
