Ontario Child Health Study (OCHS)
Summary of changes
Activity on this program started: 1983
For the follow-up study in 2000, Statistics Canada attempted to locate the original longitudinal respondents from the 1983 sample. In total, 2,896 of the 3,294 longitudinal respondents were located.
Sampling - All children and families who participated in the original OCHS were eligible for follow-up in 1987. Among the 1,869 households, 1,660 (88.8%) were traced and 1,546 (82.7%) agreed to participate.
Statistics Canada, in conjunction with McMaster University, collected information on a representative group of 3,294 Ontario children living in 1,869 families. The children selected were between 4 and 16 years of age. The main purpose of the study was to look at the overall health of the children in Ontario, to see how their health needs were being met and to identify factors that helped or hindered their development.
