description Summary Objective This study aimed to examine the secular trends in body mass index (BMI) and waist circumference (WC), and the prevalence of general and abdominal obesity among Chinese children and adolescents from 1993 to 2009. Methods Data were obtained from the China Health and Nutrition Survey conducted from 1993 to 2009. 9693 children and adolescents aged 6–17 years were included in this study, with their height, weight and WC measured. General obesity was defined using the BMI cut‐offs for overweight recommended by the International Obesity Task Force, and abdominal obesity was assessed when a WC is above the 90th percentile for gender and age. Results Among the total participants, mean BMI and WC increased significantly over the period 1993–2009: BMI increased from 17.6 to 17.8 kg m−2, and WC increased from 61.4 to 63.1 cm (both increases P
