Research Findings Resulting from OHS Data

Evaluation of Adiposity and Cognitive Function in Adults

Apr 4, 2022

An analysis of data from two cohort studies, the Canadian Alliance for Healthy Hearts and Minds (CAHHM) which includes a subset of OHS and CanPath participants, and the Prospective Urban Rural Epidemiological–Mind (PURE-MIND) study, suggests that adiposity or excess body fat is associated with lower cognitive scores.

A large Canadian cohort provides insights into the genetic architecture of human hair colour

Feb 15, 2022

Differences in hair and eye color (pigmentation) are principally determined by our genes rather than our environment. To determine the genetic variants that are associated with having blonde, red and brown hair, researchers selected a sample of 12,741 CanPath participants of European ancestry (including more than 700 participants from the OHS). People with European ancestors tend to have a high diversity of hair and eye colour. Researchers then conducted a meta-analysis of genome-wide association studies (GWAS), the results of which shed light on how pigmentation is regulated in humans.

The Utility of Occupational Health Data in the Canadian Partnership for Tomorrow’s Health (CanPath)

Feb 15, 2022

Authors from five CanPath cohorts presented a poster detailing the vast data and biosample holdings of the research platform and its overall utility as a powerful tool for population health research. CanPath’s harmonized dataset contains 1,477 variables, many of which are particularly relevant to occupational health researchers.
