Manlos et al developed the Childhood Obesity Risk Evaluation (CORE) Index to estimate the risk of late childhood obesity. It uses perinatal and family information to identify a child at increased risk for obesity. The authors are from multiple universities in Greece.
Outcome: obesity when a 9 to 13 year old schoolchild (fifth and sixth grades)
Parameters:
(1) gender of the patient
(2) maternal smoking during pregnancy
(3) maternal prepregnancy weight
(4) maternal education
(5) weight gain during infancy from birth to 6 months (based on z-score)

total score =
= SUM(points for 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 11
• The higher the score the greater the risk for late childhood obesity.
The conversion from score to risk is shown in Figure 1. If the data is analyzed then the following equation is generated:
percent of patients with these features who develop obesity =
= (0.2163 * ((score)^2)) + (0.475 * (score)) + 3.364
Performance:
• The sensitivity was 54% and specificity 65%, with an area under the ROC curve of 0.64.
