OBJECTIVE: The aim of this study was to describe changes in waist circumference (WC) and prevalence of abdominal obesity over a period of 10 years among Chinese adults in different socio-economic status (SES). METHODS: Data derived from the China Nutrition and Health Surveillance during 2002 and 2010-2012. We calculated the mean WC and the prevalence of abdominal obesity by gender, place of residence, SES indicators (education, income, and marital status), and body mass index (BMI) categoriesand used pooled t-tests to assess the differences between the two time periods. RESULTS: 26.0% of men and 25.3% of women had abdominal obesity in 2010-2012. The age-adjusted mean WC increased by 2.7 cm among men and 2.1 cm among women; the age-adjusted prevalence of abdominal obesity increased by 7.7% among men and 5.3% among women. The rising trends were observed in all subgroups except for a negative growth in high-income women. People living in rural areas with low education and income and with a BMI of 18.5 to 23.9 kg/m2 had a greater absolute and relative increase in WC. People living in rural areas with low income had a greater relative increase in abdominal obesity. CONCLUSION: The mean WC and prevalence of abdominal obesity among Chinese adults have increased during the past 10 years. Gender differences were noted using various SES indicators.
