Some prevalence data was limited by data availability; many rates presented here may not be nationally representative. Only data collected since 2000 were used and we report statistics for those countries with large population sizes within each region as examples. We also added some additional data (main data source: IASO, 2012).
We updated the rates based on more recent results (Ogden et al., 2012).
The rates were higher than other reported prevalence (Wang et al., 2009); and this might be due to sample differences.
We added the rates based on results from a large nationwide sample (International Institute for Population Sciences and Macro International, 2007).
We added the rates based on results from a large nationwide sample (Ji and Cheng, 2009).
We updated the rates based on more recent results of a nationwide survey (Song et al., 2010).
