Variation in ultra‐processed food consumption from 6 to 15 years, body weight and body composition at 15 years of age at The Pelotas 2004 Birth Cohort
Authors' conclusion
In crude and adjusted analyses there was a strong association between high UPF consumption from childhood to adolescence, EW and higher body fat parameters at 15 years, but its deleterious association with body adiposity was only uncovered after adjusting for confounders.
Study context
- Population
- Birth cohort participants with daily ultra-processed food (UPF) consumption estimated by Food Frequency Questionnaires at 6 and 15 years; body composition by air-displacement plethysmography at 15 years≈1 in 7 always-high consumers
- Participants
- 1,584 participants
- Exposure
- Always-high vs always-low UPF consumption from 6 to 15 years
- Outcome
- Excessive weight (BMI-for-age ≥+1 z-score) and body composition (FM, FFM, %FM, %FFM, FMI, FFMI by air-displacement plethysmography)
- Follow-up
- 15 years
Methodological detailsprospective follow-up at 6 and 15 years
- Prospective follow-up at 6 and 15 years
Main finding
As reported in the abstract
Females: always-high consumers had on average more FM and FMI than always-low consumers
32%
Observational data: associations, not effects.
Further findings
EW and body fat (crude analyses) · 15 years
- No association between variation in UPF consumption and EW
- Body fat parameters lower in always-high than always-low consumers, both sexes
- Crude analyses
