The China Jintan Child Cohort Study follows the development of over 1,500 pre-school children in the city of Jintan, China. Participants were recruited between autumn 2004 and spring 2005 when aged between 3 and 6 years old from 4 pre-schools in Jintan, with the schools chosen to be representative of the geographic, social, and economic profile of the whole city. The cohort consisted of 55.5% boys, 44.5% girls, and 99.8% Han ethnicity, which when compared to census data for the city, indicated a representative sample of the city in terms of sex and Han ethnicity distribution for this age range.
