Prevalence, detection, treatment, and control of hypertension in human immunodeficiency virus (HIV)-infected patients attending HIV clinics in the Western Cape Province, South Africa
Bibliographic record
Abstract
Representative data on the prevalence of hypertension, a major non-infectious comorbidity in human immunodeficiency virus (HIV)-infected people, is lacking. We assessed the prevalence, awareness, treatment, and control, as well as determinants of hypertension in HIV-infected adults in South Africa.A cross-sectional survey was conducted between March 2014 and February 2015 in a random sample of 827 adults (77.7% women), receiving care for HIV infection at 17 randomly selected public health facilities across the Western Cape Province, South Africa.Participants' mean age was 38.4 years overall, 41.1 years in men and 37.7 years in women (P < .001). The median diagnosed duration of HIV infection, similar in men and women, was 5 years, while the median CD4 count was 381 cell/mm. Age-standardized prevalence, awareness, treatment, and control of hypertension was 38.6% (95% CI: 34.3-42.9), 46.3% (37.7-54.9), 76.4% (61.1-91.7), and 81.1% (62.9-99.3) in the overall sample; 40.0% (30.0-50.0), 36.3% (17.6-55.0), 84.8% (38.3-131.3), and 87.0% (38.2-135.8) in men; and 37.7% (32.9-42.5), 48.9% (38.9-58.9), 75.8% (59.1-92.5), and 81.3% (61.1-101.5) in women. Age and education were weakly associated with prevalent hypertension, while CD4 count and diagnosed duration of HIV infection were unrelated to prevalent hypertension.Similar to reports in the general population in this and other countries in the region, hypertension is frequent in young South Africans receiving care for HIV infection, with similar diagnostic and treatment gaps. Integrating HIV and non-communicable disease (NCD) prevention and care will, at least in part, reduce missed opportunities for implementing NCD prevention in HIV-infected people in care.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
