Proportion of US Adults Potentially Affected by the 2014 Hypertension Guideline
Bibliographic record
Abstract
IMPORTANCE: The new 2014 blood pressure (BP) guideline released by the panel members appointed to the Eighth Joint National Committee (JNC 8; 2014 BP guideline) proposed less restrictive BP targets for adults aged 60 years or older and for those with diabetes and chronic kidney disease. OBJECTIVE: To estimate the proportion of US adults potentially affected by recent changes in recommendations for management of hypertension. DESIGN: Cross-sectional, nationally representative survey. PARTICIPANTS: Using data from the National Health and Nutrition Examination Survey between 2005 and 2010 (n = 16,372), we evaluated hypertension control and treatment recommendations for US adults. MAIN OUTCOMES AND MEASURES: Proportion of adults estimated to meet guideline-based BP targets under the 2014 BP guideline and under the previous seventh Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) guideline. RESULTS: The proportion of younger adults (18-59 years) with treatment-eligible hypertension under the JNC 7 guideline was 20.3% (95% CI, 19.1%-21.4%) and decreased to 19.2% (95% CI, 18.1%-20.4%) under the 2014 BP guideline. Larger declines were observed among older adults (≥60 years), decreasing from 68.9% (95% CI, 66.9%-70.8%) under JNC 7 to 61.2% (95% CI, 59.3%-63.0%) under the 2014 BP guideline. The proportion of adults with treatment-eligible hypertension who met BP goals increased slightly for younger adults, from 41.2% (95% CI, 38.1%-44.3%) under JNC 7 to 47.5% (95% CI, 44.4%-50.6%) under the 2014 BP guideline, and more substantially for older adults, from 40.0% (95% CI, 37.8%-42.3%) under JNC 7 to 65.8% (95% CI, 63.7%-67.9%) under the 2014 BP guideline. Overall, 1.6% (95% CI, 1.3%-1.9%) of US adults aged 18-59 years and 27.6% (95% CI, 25.9%-29.3%) of adults aged 60 years or older were receiving BP-lowering medication and meeting more stringent JNC 7 targets. These patients may be eligible for less stringent or no BP therapy with the 2014 BP guideline. CONCLUSIONS AND RELEVANCE: Compared with the JNC 7 guideline, the 2014 BP guideline from the panel members appointed to the JNC 8 was associated with a reduction in the proportion of US adults recommended for hypertension treatment and a substantial increase in the proportion of adults considered to have achieved goal BP, primarily in older adults.

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.
