Among 156 villages and communities in 20 counties or districts and 13,010 households, 15,600 adults were selected. Of the 15,600 adults, 14,230 responded (91.2% response rate), and 1,370 did not respond. Of the adults who did not respond, 1,120 were replaced by adults with the same profile in the same village or community. The reasons for replacement were the following: out, 30.6%; absent, 56.1%; refused, 11.7%; and other, 1.6%. There were 15,350 participants in the survey: 7,683 men and 7,667 women. All (n = 15,350) participated in the physical measurements (response rate, 100%); 2,208 participated in the 24-hour dietary recall survey (response rate, 98%), and 2,112 participated in the 24-hour urine and blood sample collection (response rate, 96.7%).
