Hypertension Awareness and Control Among Middle-aged and Older Adults in Canada: Findings from the Canadian Longitudinal Study on Aging
Bibliographic record
Abstract
Hypertension awareness and control reflect healthcare system efficacy to identify the condition and manage its burden. This thesis aimed to determine the prevalence of undetected and uncontrolled hypertension, and their association with social determinants in middle to older-aged adults. Current literature was reviewed, followed by a cross-sectional analysis of Canadian Longitudinal Study on Aging (CLSA) data. Hypertension prevalence in the cohort was 45.5%, of which 14.7% of hypertensives were undetected and 22% uncontrolled. Multivariable analysis results suggest that younger age and active employment are associated with undetected hypertension, and that older age, males, lower household income, and not graduating high school are associated with uncontrolled hypertension. Both outcomes were also strongly associated with not seeing a physician and not checking blood pressure in the last year. We recommend that future research identify and evaluate policies that are tailored to groups with high rates of undetected and uncontrolled hypertension.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
