Association between dietary inflammatory index and anthropometric indicators of adiposity in Brazilian adolescents
Authors' conclusion
The findings showed a direct association between the dietary inflammatory potential measured by DII and adiposity.
Study context
- Population
- Brazilian adolescents aged 12–17 years, Study of Cardiovascular Risks in Adolescents
- Participants
- 71,740 adolescents
- Exposure
- 4th vs 1st quartile of Dietary Inflammatory Index
- Outcome
- Overweight (BMI-for-age and sex >1 z-score), abdominal obesity (waist circumference (WC) >80th percentile) and waist-to-height ratio (WHtR) > 0.50
Methodological detailsFood consumption assessed by one 24-h dietary recall; Dietary Inflammatory Index (DII) estimated using 39 food parameters
- Food consumption assessed by one 24-h dietary recall; DII estimated using 39 food parameters
