The data collected are de-identified (meaning it is connected to an ID number, not to your name or any other personal identifying information). No identifiable information will be shared with anyone outside of our established CLSA protocols. The data from this part of the study are kept, like all CLSA data, on secure servers located at McMaster University. The stool samples will be stored in freezers located at McMaster University.
CLSA CORE STUDY
CLSA participants who visit Data Collection Sites have the option to collect a stool sample using a self-collection kit at their home between their in-home interview and Data Collection Site visit.
Participants will be asked to provide a sample once every three years.
