How were the people who participated in the DEARS monitoring selected?
Participant households were selected based primarily on where their residence was located. Randomly selected homes had to be from one of the pre-selected neighborhoods which offered scientists a wide range of environmental conditions to study. The study included adults 18 and older who lived in single-family homes (e.g., not apartments), who were physically able to move around on their own, nonsmokers, and capable of providing informed consent concerning their participation. Selection criteria had no exclusion based on race, sex, occupation, religious affiliation or socio-economic status of participants.
