Background

Evidence indicates that central adiposity has increased to a higher degree than general adiposity in children and adolescents in recent decades. However, waist circumference is not a routine measurement in clinical practice.

Objective

This study aimed to determine the prevalence of abdominal obesity based on waist circumferences WC and waist to height ratio WHtR in Spanish children and adolescents aged 6 to 17 years. Further, the prevalence of abdominal obesity AO among normal and overweight individuals was analyzed.

Design

Data were obtained from a study conducted from 1998 to 2000 in a representative national sample of 1521 children and adolescents aged 6 to 17 years 50.0% female in Spain. WC and WHtR measurements were obtained in addition to BMI. AO was defined as WHtR ≥0.50 WHtR-AO, sex and age specific WC≥90th percentile WC-AO1, and sex and age specific WC cut-off values associated with high trunk fat measured by by dual-energy X-ray absorptiometry WC-AO2.

Results

IOTF- based overweight and obsity prevalence was 21.5% and 6.6% in children and 17.4% and 5.2% in adolescents, respectively. Abdominal obesity AO was defined as WHtR≥0.50 WHtR-AO, sex- and age-specific WC≥90th percentile WC-AO1, and sex- and age-specific WC cut-off values associated with high trunk fat measured by dual-energy X-ray absorptiometry WC-AO2. The respective prevalence of WHtR-AO, WC-AO1, and WC-AO2 was 21.3% 24.6% boys; 17.9% girls, 9.4% 9.1% boys; 9.7% girls, and 26.8% 30.6% boys;22.9% girls in children and 14.3% 20.0% boys; 8.7% girls, 9.6% 9.8% boys; 9.5% girls, and 21.1% 28.8% boys; 13.7% girls in adolescents.

Conclusion

The prevalence of AO in Spanish children and adolescents is of concern. The high proportion of AO observed in young patients who are normal weight or overweight indicates a need to include waist circumference measurements in routine clinical practice.
