Objective: To understand the prevalence of overweight and obesity among adults of 5 monitoring areas in Guizhou Province and to analyze the correlation between overweight, obesity and incidence of related chronic diseases.
Methods: Multistage stratified cluster random sampling was employed, using data from "the 2010- 2012 National Nutrition and Health Survey". The physical measurement and the TC, TG, HDLC and blood glucose were conducted among 3682 resident population aged 18 years and above who from 5 monitoring areas( Yunyan and Baiyun District, Dejiang, Qianxi andSansui County in Guizhou Province). To analyze the distribution of overweight, obesity and central obesity in the population and its relationship with diabetes, dyslipidemia and hypertension.
Results: The prevalence rates were 27%, 7. 5% and 16. 9% for overweight, obesity and the central obesity in 5 surveillance areas of Guizhou Provinc. The central obesity rate increase with age, which was the highest in the elderly( over 60years)( χ~2= 32. 03, P < 0. 001), the female were higher than the male( χ~2= 4. 2, P =0. 04). Under controlling for age, gender, regional factors, compared with the normal weight population, the onset risk of diabetes, hyperlipidemia and hypertension in the overweight populations were 1. 4 times, 1. 4 times and 2 times( 95% CI 1. 0- 2. 0, 1. 2-1. 7, 1. 6- 2. 5, P < 0. 05) respectively. The risk of obesity diabetes, hyperlipidemia and hypertension were 2. 6 times( 95% CI 1. 7- 4. 1, P < 0. 001), 1. 5 times( 95% CI 1. 1-1. 9, P < 0. 001) and 3. 7 times( 95% CI 2. 7- 5. 1, P < 0. 001), respectively. Central obesity may increase the risk of diabetes( OR = 2. 18, 95% CI 1. 58- 3. 01, P < 0. 001)and the risk of hypertension( OR = 2. 2, 95% CI 1. 74- 2. 57, P < 0. 001).
Conclusion: Adult overweight and obesity were risk factors of diabetes, dyslipidemia and hypertension risk factors. Central obesity were risk factors of diabetes and hypertension risk factors.
