The blood glucose level and diabetes prevalence in Chinese adults from 2010 to 2012

Objective To analyse the blood glucose level and the diabetes prevalence in Chinese adults aged 18 and above from 2010 to 2012. Methods Data was collected from 2010- 2012 Chinese Nutrition and Health Surveillance. Participants were recruited using a complex, multistage, and probability sampling design. A total of 116 068 residents aged 18 and above from 150 counties in 31 provinces in China were included to assess the diabetes prevalence based on two criteria. One was the criterion proposed by WHO Global Monitoring Framework(FBG≥7.0 or diagnosed diabetes patients who are using medicines) in 2013. Another one was the 1999 International Diabetes Federal(IDF) criterion. Age and sex standardization was performed based on the China 2009 population published by National Statistics Bureau and they were seen as the standard population. The glucose level and the prevalence of diabetes after weight adjustment for complex sampling were reported. Results The average FBG level(±s) was (5.28±0.03)mmol/L in Chinese adults, and it was (5.30±0.03)mmol/L and (5.26±0.03)mmol/L for male and female, respectively. The average FBG levels were (5.09±0.03),(5.47±0.04), and (5.64±0.05)mmol/L in young aged group (18-44 years old), middle aged group (45-59 years old)and elderly aged group(≥60 years old), respectively. The average FBG level was (5.35±0.04)mmol/L and (5.22±0.06)mmol/L in urban and rural residents, respectively. According to the criteria of WHO Global Monitoring Framework, the diabetes prevalence of Chinese adults was 5.7% (95%CI:5.1% - 6.2%), and 6.4% (95%CI:5.6% - 7.3%)and 4.9% (95% CI: 4.1%-5.7%) in urban and rural residents, respectively. According to the criteria of IDF, the diabetes prevalence of Chinese adults was 6.8% (95%CI:6.2% - 7.4%), and 7.6% (95%CI:6.7% - 8.6%)and 6.0% (95%CI: 5.0% - 6.9%)in urban and rural, respectively. Conclusion The FBG level and prevalence of diabetes in Chinese adults in 2010-2012 were pretty high. It is essential to continue to strengthen diabetes prevention and control.
