Abstract: Objective To comprehensively describe the prevalence of abdominal obesity among children and adolescents in the urban area of Jinan, using different definitions of waist circumference (WC) and waist to height ratio (WHtR), in order to provide a scientific evidence for obesity prevention in children and adolescents.Methods Data were from the Twelfth Five-year National Science and Technology Support Program "Early Warning, Diagnosis and Treatment of Cardiovascular Disease in Children" conducted in Jinan from September, 2012 to September, 2014. Abdominal obesity was evaluated using different WC and WHtR standards. Chi-Squared test was used to compare the sex-difference on prevalence of abdominal obesity within different ages and the kappa value was calculated to compare the agreements of different definitions using WC and WHtR. Results The prevalence of abdominal obesity was 28.1% (WC-Chinese standard), 22.2% (WC-Beijing standard), 17.7% (WHtR-International standard) and 27.3% (WHtR-Chinese standard) respectively. In children aged 7~11 years, there was an upward trend in the prevalence of abdominal obesity with age. In adolescents aged 12~17 years, there was a downward trend with age. Regardless of the used standards, the prevalence of abdominal obesity in adolescent boys was significantly higher than that in adolescent girls. Conclusions In urban area of Jinan, abdominal obesity in children and adolescents is prevalent, and more attentions should be paid by related government and education departments.
