Quantifying the childhood and adolescent overnutrition attributable to specific risk factors: The Young Lives Study in Peru
Authors' conclusion
This study provides evidence on the risk of overweight and obesity attributable to diet habits, physical activity and the obesogenic niche among children and adolescents in Peru, which may guide the implementation of evidence-based interventions.
Study context
- Population
- Children of the younger cohort of the Young Lives Study in Peru (2002–2017), mean age 1 (SD 0.4) year at baseline, 50% girlsenrolled at baseline
- Participants
- 2,052 children
- Primary endpoint
- Incidence of overweight and obesity (WHO standards) and the risk attributable to specific risk factors (IRRs, population attributable fractions (PAFs))
- Follow-up
- 14 (SD 0.5) years
Methodological detailsprospective cohort, multilevel Poisson regression
- Prospective cohort
- Multilevel Poisson regression
Primary result
As reported in the abstract
- Incidence of overweight, per 100 person-year
- 7.9 (95% CI 7.6-8.2)
- Incidence of obesity, per 100 person-year
