Establishing a population-based cohort in Alberta for chronic disease research is feasible. Most participants agreed to data linkage and future blood sampling, supporting biomarker studies.

Area of Science:

Epidemiology
Population Health
Biostatistics

Background:

Growing privacy concerns challenge the creation of new cohorts for chronic disease etiology studies.
Previous research on cohort feasibility in similar contexts is limited.
Understanding participant willingness for data linkage and biospecimen collection is crucial for future research.

Purpose of the Study:

To determine the feasibility of recruiting a geographically dispersed, population-based cohort in Alberta.
To assess participant consent for accessing provincial healthcare utilization data.
To evaluate willingness for future blood sample collection for biomarker analysis.

Main Methods:

Random digit dialling was used to recruit 22,652 men and women aged 35-69 without diagnosed cancer.

Enrollment involved 11,865 participants (52.4%) representing 84% of Alberta communities.

Consent rates for health data linkage (97%) and future blood sampling (91%) were recorded.

Main Results:

A geographically dispersed cohort of 11,865 individuals was successfully established.
High consent rates were achieved for health data linkage (97%) and future blood sampling (91%).
Cohort demographics showed similarities to the Canadian Community Health Survey but with notable differences in education, smoking, and obesity.

Conclusions:

Establishing a geographically dispersed, population-based cohort for chronic disease research is feasible in Canada.
Participant consent for data linkage and biospecimen collection supports the viability of such studies.
The established cohort provides a valuable resource for future epidemiological and biomarker research on chronic diseases.
