Overfat cutoffs and the optimal combination of body fat indices for detecting cardiometabolic risk among school‐aged children
Authors' conclusion
Both the optimal and simplified overfat cutoffs were provided for the Chinese pediatric population. The use of FMI and TLR together allows for adequate screening of CMR and its clustering.
Study context
- Population
- Chinese children aged 6 to 18 years (50.3% boys); body fat indices (fat mass index (FMI), body fat percentage, TLR, android to gynoid fat ratio) from DXA50.3% boys
- Participants
- 8,710 children
- Exposure
- Body fat indices (DXA) vs anthropometry-based obesity measures (BMI, waist circumference) for detecting cardiometabolic risk
- Outcome
- AUC for identifying cardiometabolic risk (CMR) and its clustering; optimal overfat cutoffs of body fat indices
Main finding
As reported in the abstract
Discrimination of CMR and its clustering (AUC)
Optimal overfat cutoffs in girls: FMI at 80th percentile, TLR at 75th percentile
80th percentile (FMI); 75th percentile (TLR)
Observational data: associations, not effects.
Further findings
Simplified thresholds from age-group-merged cutoffs
- Simplified thresholds showed similar performance as optimal cutoffs in detecting cardiometabolic risk (CMR)
