Smokeless tobacco use and oral potentially malignant disorders among people living with HIV (PLHIV) in Pune, India: Implications for oral cancer screening in PLHIV.

ABSTRACT:

Introduction

In India, smokeless tobacco (SLT) is a predominant form of tobacco used among people living with HIV (PLHIV). Despite SLT being a risk factor for oral potentially malignant disorders (OPMDs), no prior studies have quantified the association of OPMDs with SLT use among PLHIV. This limits the planning of preventive and control strategies for oral cancer among PLHIV, who are at higher risk for the disease.

Methods

We enrolled 601 PLHIV and 633 HIV-uninfected individuals in an oral cancer screening study at BJ Government Medical College, Pune, India. Oral cavity images were collected using an m-Health application and reviewed by three clinicians. Participants with two clinician positive diagnoses were deemed to have suspected OPMDs. Prevalence ratios (PRs) were used to quantify the association between suspected OPMDs and SLT use among PLHIV. PRs for current SLT users, across HIV status and use duration were also estimated. Corrected PRs were obtained by modifying the maximum likelihood estimation. Models were adjusted for age, smoking, alcohol use and CD4 counts.

Results

Of those enrolled, 61% were men, median age was 36 years (IQR: 28-44), and 33% currently use SLT. Proportion of current SLT users was similar across PLHIV and HIV-uninfected groups but use duration for current SLT use was higher among PLHIV(p<0.05). Among PLHIV, current SLT users had a 5-times (95% CI:3.1-7.0) higher prevalence of suspected OPMDs, compared to non-users. Relative to HIV uninfected individuals with the same SLT use duration, significant associations with suspected OPMDs were seen for PLHIV with<10 use years (PR: 3.5, 95% CI: 1.5-8.1) but not for PLHIV with≥10 use years (PR: 1.3, 95% CI: 0.9-1.8).

Conclusion

PLHIV that are current SLT users are at high risk of OPMDs and potentially oral cancer. The development of strategies for screening, early detection, and management of OPMDs must be considered for this group.

Project description:Introduction : There is a dearth of data on anxiety related to the COVID-19 pandemic from people living with HIV (PLHIV). This is a cause of concern as anxiety is associated with antiretroviral therapy (ART) nonadherence. Globally, India has the third largest population of PLHIV and third highest number of COVID-19 cases which are rapidly increasing. Therefore, it is crucial to understand the burden of anxiety and its sources among Asian Indian PLHIV during this pandemic. Methods: We used data from a telephonically delivered assessment among PLHIV engaged in care at a tertiary healthcare associated antiretroviral therapy (ART) center in Pune, India. Assessments were conducted between April 21 and May 28, 2020, one month into the government mandated lockdown. GAD-7 was used to assess for anxiety over two-preceding weeks. Significant sociodemographic and clinical differences between groups (GAD-7<10 and GAD-7?10) were assessed using Fisher's exact and Wilcoxson rank sum tests, for categorical and continuous variables, respectively. Thematic analysis was employed to analyze an open-ended question that asked about the most pressing cause(s) of concern. Results : Of 167 PLHIV contacted, median age was 44 years (IQR:40 - 50), 60% (n=100) were cisgender women and 81% (n=135) had a monthly family income<200 USD. Thirty-eight percent (n=64) had prior history of tuberculosis and 27% (n=45) were living with another comorbidity. A fourth (25%, n=41) had GAD-7 scores indicative of generalized anxiety. PLHIV who had fewer remaining doses of ART had significantly higher GAD-7 scores compared to those that had more doses (p=0.05). Thematic analysis indicated that concerns were both health related and unrelated, and stated temporally. Present concerns were often also projected as future concerns. Conclusions : In a group of socioeconomically disadvantaged PLHIV, a fourth were found to have anxiety, that appeared to be influenced by concerns about ART availability. Furthermore, the persistence of sources of anxiety and therefore an increase in anxiety for these PLHIV is anticipated as the pandemic worsens in India. We recommend the regular utilization of short screening tools for anxiety to monitor and triage PLHIV as an extension of current HIV-services.

Project description:IntroductionDespite the high burden of tobacco use in India, users do not have access to adequate help. This pilot trial aimed to evaluate the feasibility and acceptability of a text messaging intervention for tobacco cessation, generate preliminary estimates of its impact, and fine-tune procedures for a definitive trial.Aims and methodsParallel two-arm single blind individually randomized controlled pilot trial with nested qualitative study. Participants included adult current tobacco users (smoked and smokeless). Eligible and consenting participants were randomized to receive either (1) text messaging intervention (ToQuit) which covered specific content areas such as psychoeducation about consequences of tobacco use and benefits of quitting and tobacco avoidance strategies or (2) information about tobacco cessation helplines such as the helpline number and the languages in which tobacco cessation support was available (control). Feasibility data included screening and consent rates, treatment dropouts, and outcome ascertainment. The primary abstinence outcome was self-reported abstinence from tobacco in the past seven days at 3 months post-randomization. In-depth interviews were conducted with a subsample of participants primarily to collect acceptability data. The primary abstinence analysis used a chi-squared test and logistic regression (complete case), and qualitative data was analyzed using thematic analysis.ResultsNinety-eight participants were randomized into the two trial arms; 77 (79%) completed outcome evaluation. No between-arm differences in abstinence were found though findings favored the intervention (7-day abstinence: ToQuit 23%, control 19%; adjusted odds ratio 1.23, 95% confidence interval 0.38, 3.97). Participants appreciated the language, comprehensibility, and relevance of the messages; and reported overall satisfaction with and positive impact from the intervention on their lives.ConclusionsThe findings indicate the acceptability and feasibility of ToQuit and if found effective, it could be a potentially scalable first-line response to tobacco use in low-resource settings.ImplicationsOur pilot randomized control trial provides sufficient findings supporting the acceptability and feasibility of an intervention for tobacco cessation which is suitable for a context which has a shortage of healthcare workers and for individuals who use smoked or smokeless tobacco. This is critical on a background of limited contextually relevant interventions for a problem with a high burden in low- and middle-income countries such as India.

Project description:IntroductionAlthough most of the disease burden internationally is due to tobacco smoking, smokeless tobacco (SLT) use contributed to an estimated 76 000 deaths in 2017. We have studied the potential risk factors for SLT use among adolescents in South India.MethodsA cross-sectional questionnaire survey of all students in grades 6-8 in schools in the Udupi district of Karnataka State ascertained SLT use status and potential determinants of SLT uptake. Ever SLT use was defined as any reported consumption of any SLT products, currently or at any time in the past. Independent effects on ever SLT use status were estimated using multiple logistic regression.ResultsOf 46 706 students from 914 participating schools, 39 282 (84.1%) provided questionnaire responses sufficiently complete for analysis. Ever SLT use was reported by 775 (2.0%) participants and in a mutually adjusted model was significantly related to age, male sex, family use, or friend's use of SLT, low socioeconomic status, high rebelliousness, and low self-esteem. After controlling for these effects, the odds of ever-SLT use were significantly higher among students who had least awareness of the harmful effects of tobacco use (odds ratio 3.7, 95% confidence interval [2.9, 4.7]) and significantly lower among those not exposed to tobacco advertising (odds ratio 0.7, 95% confidence interval [0.5, 0.8]).ConclusionsThe prevalence of SLT use among children in Karnataka is relatively low when compared with other studies in India. The significant potential risk factors of SLT use include low awareness of the harmful effects of tobacco and tobacco control policies and exposure to tobacco advertising.ImplicationsThe prevalence of SLT use among school going adolescents in South India is relatively low. The potential risk factors for SLT use among adolescents in southern India are similar to those for smoked tobacco. It includes age, male gender, family or friend's use of SLT, low socioeconomic status, high rebelliousness, low self-esteem, exposure to tobacco advertisement and least awareness about the harmful effects of tobacco and of tobacco control policies. The present study lays emphasis regarding creating awareness about tobacco harms and control policies for further reducing tobacco use among adolescents.
