Lack of association between activity or fitness and loss of control of hypertension.
Bibliographic record
Abstract
BACKGROUND: Many treated hypertensive patients have inadequate control of their blood pressure. Physical activity and cardiorespiratory fitness are important in the development and treatment of hypertension. Less is known about their relationships with hypertension control in the context of long-term management. OBJECTIVES: To identify whether patients with lower levels of activity or fitness are at risk for loss of control of hypertension. METHODS: Follow-up blood pressure measurements were recorded over the period of a year in a cohort of initially controlled hypertensive patients, under the care of 50 family physicians in a variety of practice settings. A questionnaire for a one-year recall of leisure time physical activity and the Step Test, an indirect measure of maximal oxygen consumption, were administered to the patients at the end of the period of blood pressure observations. The study group for the activity questionnaire consisted of 385 patients; 310 of whom undertook the fitness test. Sociodemographic, clinical and lifestyle factors were analyzed as potential confounders in the relationships of main interest in this study: between activity and fitness, respectively, with loss of control of hypertension. RESULTS: Sixteen per cent of patients (95% CI 12, 20) had an increase of 20 mmHg systolic or 10 mmHg diastolic from baseline to the average of three follow-up blood pressures, and 14% (95% CI 11, 18) had blood pressures above the entry thresholds on at least two of three follow-up visits. No associations were found between loss of control of hypertension and physical activity or cardiorespiratory fitness. CONCLUSIONS: Lower levels of physical activity and fitness are not associated with loss of hypertension control. The identification of patients at risk for loss of hypertension control, which could be useful in targeting selected groups for increased follow-up and in understanding the high prevalence of uncontrolled hypertension, requires further study.

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.
