Insights
Accurate height and BMI measurements can quickly differentiate simple obesity from Cushing's disease (CD) in children. This simple method may avoid the need for complex diagnostic investigations.
Area of Science:
- Pediatric Endocrinology
- Pediatric Obesity
- Diagnostic Discrimination
Background:
- Rising childhood obesity rates increase referrals for endocrine/metabolic evaluations.
- Excluding Cushing's disease (CD) in overweight children often requires complex tests.
Purpose of the Study:
- To assess the diagnostic accuracy of height, weight, and BMI measurements.
- To differentiate simple obesity (SO) from Cushing's disease (CD) in pediatric patients.
Main Methods:
- Measured height, weight, and BMI in 25 pediatric patients with CD and 41 with SO.
- Calculated BMI standard deviation scores (SDS) and height SDS.
- Analyzed the ratio of BMI SDS to height SDS.
Main Results:
- Children with CD had a lower mean BMI SDS compared to those with SO.
- Height SDS was significantly lower in CD patients versus SO patients.
- The BMI SDS to height SDS ratio was significantly decreased in CD patients.
Conclusions:
- Simple height and BMI SDS measurements offer a sensitive and rapid diagnostic tool.
- These measurements can help distinguish pediatric Cushing's disease from simple obesity.
- This approach may reduce the need for invasive diagnostic procedures.
Background:
Increasing prevalence of childhood obesity has resulted in an accelerating rate of referrals of overweight patients to pediatric clinics for exclusion of endocrine or metabolic etiologies. The exclusion of Cushing's disease (CD) requires complex and potentially invasive investigations.
Objective:
To evaluate the sensitivity of accurate measurements of height, weight and body mass index (BMI) in discriminating between simple obesity and CD.
Methods And Patients:
Height, weight and BMI were measured at diagnosis in 25 patients with CD; 14 males, 11 females, mean age 12.9 yr (6.4-17.8) and 41 patients with simple obesity (SO), defined as BMI >2.0 SD; 20 males, 21 females, mean age 9.4 yr (3.5-15.6).
Results:
Mean (+/-SE) BMI SDS in the CD patients was 2.41+/-0.5 and in the SO patients 3.71+/-1.3. Height SDS in the CD patients was -1.88+/-0.24 and in the SO patients 1.18+/-0.19 (p<0.05). The mean (+/-SE) BMI SDS to height SDS ratio was significantly decreased in the CD compared with the SO patients; -1.81+/-0.54 vs +0.90+/-1.17 (p<0.0001).
Conclusions:
Simple, accurate measurement of height and BMI SDS values provides a quick, and sensitive diagnostic discriminator in pediatric patients with CD or SO, thus potentially avoiding complex investigations.
