Description
Summary:Obesity epidemic is related to industrialization and urbanization that have lead to changes in nutrition, lifestyle and socio-economic status. However, information on the trajectory of the obesity epidemic in populations experiencing rapid economic development is limited. We therefore investigate trends in obesity from 2002 to 2010 in a southern Chinese population experiencing world's fastest economic development. Between 2002 and 2010 four standardized surveys were conducted in a population of 85 million residents in Guangdong, China. Multistage cluster sampling was adopted to recruit representative samples. Weight, height and waist circumference of the participants were measured in a standardized way. The analysis included residents aged between 18 and 69 years. The number of participants included in the present analysis for Surveys conducted in 2002, 2004, 2007 and 2010 were 13058, 7646, 6441 and 8575, respectively. From year 2002 to 2010, the age-standardized Body mass index (BMI) insignificantly changed from 21.7  kg m(-2) to 22.3  kg m(-2), and the prevalence of overweight and overall obesity from 15.8 to 16.6% (both P>0.05). The age-standardized waist circumference increased from 73.7 to 78.4 cm, and prevalence of abdominal obesity increased from 12.9 to 23.7% (both P
