Cognitive Impairment Among Aging People Living With HIV on Antiretroviral Therapy: A Cross-Sectional Study in Hunan, China
Bibliographic record
Abstract
Our cross-sectional study examined the prevalence of cognitive impairment among people living with HIV (PLWH) aged 60 years or older. The sample, composed of 250 PLWH, was recruited from 2 clinics in Hunan, China. Structured questionnaires guided face-to-face interviews, including items addressing demographic characteristics, regimens of antiretroviral therapy, and cognitive status as measured by the Montreal Cognitive Assessment. Findings revealed cognitive function of this population was significantly lower than that of uninfected individuals based on historical comparisons; 87.2% (n = 218) of PLWH in our study had cognitive impairment. Global cognitive function as well as the domains of language and orientation decreased with age. Global cognitive function was associated with sex and education, but not with antiretroviral therapy regimens. These findings support an urgent need to include routine screening for cognitive function in older PLWH and the need to consider the complexity of the evaluation process.

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.
