Cohort Profile: The Ontario Health Study (OHS)
OHS’s cohort profile outlines its research platform’s history and value for the broader scientific community. OHS follows 225,000 over their lifetime, actively and passively, making de-identified genomic, environmental, lifestyle, and electronic health data available to cancer and chronic disease researchers.
The Relationship of Sleep Duration with Ethnicity and Chronic Disease in a Canadian General Population Cohort
This study used questionnaire data from the Ontario Health Study to determine how ethnicity-specific differences in sleep duration affect health outcomes. It was found that both sleep duration and ethnicity were independent significant predictors for various morbidities such as diabetes, stroke, and depression.
Physical Activity is Associated With Reduced Prevalence of Self-Reported Obstructive Sleep Apnea in a Large, General Population Cohort Study
The researchers used Ontario Health Study data to determine if physical activity would reduce the prevalence of OSA. Upon determining the prevalence of OSA, the reseachers were able to do a cross sectional analysis to determine that increased physical activity had a statistical significance of (P ≤ 0.045). Moderate activity did not have much of an impact on the prevalence of OSA. These results showed that increased physical activity would be a preventative measure for OSA.
