Rapid infant weight gain or point‐in‐time weight status: Which is the best predictor of later obesity and body composition?
Authors' conclusion
A simple measure of obesity status at a single time point between 6 and 24 months of age appeared a stronger risk factor for later obesity and FMI than RIWG assessed by any indicator, over any time frame.
Study context
- Population
- Infants with weight and length/height measured at birth, 0.5, 1, 1.5 and 2 years, followed to 11 years
- Exposure
- Rapid infant weight gain (RIWG) vs obesity status at a single time point as predictors of obesity and body composition at 11 years
- Outcome
- Obesity (BMI ≥95th percentile) and body fat (fat mass index [FMI], DXA)
- Follow-up
- 11 years
Main finding
As reported in the abstract
| Group | Sensitivity for obesity | PPV for obesity |
|---|---|---|
| RIWG | 1.5% to 62.1% | 12.5% to 33.3% |
RIWG
Sensitivity for obesity1.5% to 62.1%
PPV for obesity12.5% to 33.3%
- Obesity at any age during infancy predicted greater FMI at 11 years
- around 1.1 to 1.5 kg/m²
Observational data: associations, not effects.
