Abstract
Background: Preliminary research suggests that eating disorders (ED) are
common among overweight teenagers. Missing the diagnosis is a poor prognostic
factor. Aim: To quantify the risk of ED and the effects of age, sex and severity
of obesity in obese adolescents. Patients and Methods: We studied 99 obese
adolescents with a body mass index (BMI) > percentile 95 of CDC-NCHS, 51%
females, aged between 11 and 19 years, attending an obesity clinic. The Eating
Disorders Inventory-2 (EDI-2) was used to evaluate the risk of ED. A score equal
or higher than 110, corresponding to the 85th percentile, was considered as risky.
Results: Sixteen percent of studied adolescents had EDI scores > 110. No statistically
significant differences were observed by age, sex or severity of obesity. EDI-2
scores in participants with a BMI z score over and under 4 were 93.6 ± 33.9 and
78.2 ± 38.8 respectively (p = 0.02). A high percentage of participants had body
dissatisfaction (BD) and drive for thinness. Bulimic symptoms, inefficacy, fear
of maturity, and impulsivity scores were significantly higher among participants
with a high risk of developing ED. Conclusions: Obese adolescents have a high
risk for ED, regardless of their age and sex. The risk increases along with higher
BMI. The routine use of screening tests is fundamental for an early detection
of ED.
