Exploring factors associated with dual tobacco smoking among people living with HIV receiving care at HIV outpatient clinics in Hanoi, Vietnam.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPeople living with HIV (PLWH) who smoke face significant health risks from tobacco use, which dual use of cigarettes and waterpipes may exacerbate due to increased nicotine exposure and dependency. This study examined the sociodemographic, behavioral, psychosocial and health-related factors associated with dual smoking among PLWH receiving care at HIV clinics in Hanoi, Vietnam.
methodsThis cross-sectional study used baseline survey data from the VQUIT study, an RCT of smoking cessation interventions involving 662 PLWH from 13 outpatient clinics in Vietnam. Eligible participants were current tobacco smokers; dual smokers were those using both cigarettes and waterpipes. Multivariable logistic regression was used to identify factors associated with cigarette-only and dual use among PLWH.
resultsOver half of the study participants were dual smokers. Dual smoking was associated with a lower annual income (aOR: 1.91, 95%CI: 1.08-3.38) and higher nicotine dependence (aOR: 2.31, 95%CI: 1.62-3.31). They were less likely to report a prior quit attempt (aOR: 0.47, 95% CI: 0.33-0.68), more likely to perceive cigarettes as more harmful (aOR 1.44, 95% CI: 1.01-2.09), and more likely to report recent illicit drug use (aOR: 2.32, 95% CI: 1.26-4.24) and longer antiretroviral treatment duration (aOR: 1.06, 95% CI: 1.03-1.10). Social support for quitting lowered the odds of dual smoking (aOR: 0.62, 95% CI: 0.39-0.97).
conclusionsDual smoking was prevalent among PLWH receiving HIV care in VQUIT study and was shaped by complex sociodemographic, behavioral, and social factors. These findings emphasize the need for integrated cessation interventions in Vietnam, where dual smoking is prevalent, particularly among PLWH. Socioeconomic status and barriers to quitting, including drug use, nicotine dependence, and tobacco-related misconceptions, should be considered. Future research should examine the long-term health impacts of dual smoking and evaluate cessation strategies for PLWH in similar settings.
