Data Collection Sites (DCS)

Data collection from 30,000 CLSA participants will take place at 11 CLSA Data Collection Sites located at: University of British Columbia; Simon Fraser University; University of Victoria; University of Calgary; University of Manitoba; University of Ottawa; McMaster University; University of Sherbrooke; McGill University; Dalhousie University and Memorial University.

The two B.C. sites will be located in Vancouver (UBC) and Burnaby (SFU) and each of these will be responsible for data collection on 1500 subjects while the remaining 9 sites will be responsible for data collection on 3,000. As a data capture network the sites will be responsible for capturing the core data from 30,000 (of 50,000) participants who will undergo in-depth data collection.

Participants will move from station to station within each DCS to undergo interviews, neuropsychological tests, vision tests and audiometry, other measurements including blood pressure, carotid wall thickness, spirometry, and measures of strength and physical performance. Each participant will also undergo a DEXA to assess bone density and aortic calcification, a newly approved FDA test. Blood and urine samples will be collected in a dedicated phlebotomy suite that includes a small area for sample processing, temporary storage and shipment. Each DCS will have specially trained CLSA staff including a nurse, medical technologists, a phlebotomist and interviewers. A CLSA Co-investigator will serve as DCS director and will recruit field staff whose responsibility will be to recruit, obtain consent and conduct a face to face interview at the participant’s home prior to their assessment visit.
