An HIV-tailored quit-smoking counselling pilot intervention targeting depressive symptoms plus Nicotine Replacement Therapy
Bibliographic record
Abstract
Cardiovascular disease (CVD) rates among people living with HIV/AIDS (PHAs) are high. Rates of cigarette smoking, a leading contributor to CVD among PHAs, are 40-70% (2-3 times higher than the general population). Furthermore, PHAs have high rates of depression (40-60%), a risk factor for smoking cessation relapse. The current pilot study examined the effectiveness of a specifically tailored 5-session smoking cessation counselling programme for PHAs, which addressed depression, in combination with Nicotine Replacement Therapy (NRT) in a cohort of PHA smokers (n = 50). At 6-month follow-up, 28% of participants demonstrated biochemically verified abstinence from smoking. This result compares favourably to other quit-smoking intervention studies, particularly given the high percentage of HIV+ smokers with depression. At study baseline, 52% of HIV+ smokers scored above the clinical cut-off for depression on the Centre for Epidemiological Studies - Depression (CES-D) scale. HIV+ smokers with depression at study baseline demonstrated quantitatively lower depression at 6-month follow-up with a large effect size (d = 1), though it did not reach statistical significance (p = .058). Furthermore, those with depression were no more likely to relapse than those without depression (p = .33), suggesting that our counselling programme adequately addressed this significant barrier to smoking cessation among PHAs. Our pilot study indicates the importance of tailored programmes to help PHAs quit smoking, the significance of addressing depressive symptoms, and the need for tailored counselling programmes to enhance quit rates among PHAs.

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.
