OBJECTIVE: To collect regional reference values of waist circumference (WC), and waist/hip ratio (WHR) in children and adolescents from Merida, Venezuela, and to compare them to international references. SUBJECTS AND METHODS: A total of 919 students aged 9-17 years from public and private educational establishments were assessed. Weight, height, WC, and WHR were measured. Outliers (± 3 SD Z-Score) were excluded from the data collected. Percentile distribution of the tested variables was done by age and sex. RESULTS: Fifty-one percent of subjects were female, and 52.7% were from public institutions. WC (p=0.001) and WHR (p=0.0001) were statistically higher in boys. With advancing age, WC increased in both sexes, while WHR showed the opposite behavior (p=0.0001 for both). The 90th percentile (pc) for WC ranged from 69.7 and 83.6 cm in girls and from 69.2 and 86.7 cm in boys. The 90th pc values of WHR ranged from 0.79 and 0.91 in girls and from 0.86 and 0.93 in boys. Overall, our WC and WHR values were lower than North American values and similar to those of some Latin American references. CONCLUSION: Percentile reference charts for WC and WHR specific for age and sex, obtained from a representative sample of children and adolescents from Mérida, Venezuela, are provided. They may be used regionally, both for individual assessment and to implement prevention policies.
