RESUMO

INTRODUCTION: Recruiting special populations to smoking cessation trials is challenging and approaches beyond in-clinic recruitment may be beneficial. This secondary analysis of data from a smoking cessation RCT for individuals with a history of cervical cancer or cervical intraepithelial neoplasia (CIN) explored differences associated with in-clinic vs. online recruitment. METHODS: Participants were recruited from clinics within a university-based NCI-designated cancer center (n=87) and online nationally via Facebook (n=115). Baseline measures included sociodemographics, smoking history, and cancer or CIN history. Study retention and smoking abstinence were assessed 12 months post-baseline. Group differences in baseline characteristics were evaluated. Retention and abstinence were evaluated while controlling for group differences and predictors. RESULTS: Participants recruited online (vs. in-clinic) had higher educational attainment (p=.01) and health literacy (p=.003). They were more likely to have CIN vs. cancer, to be further from the time of diagnosis, and to have completed active treatment (p values<.001). While controlling for these group differences and independent predictors, retention was higher among participants recruited online (log-likelihood χ2(1)=11.41, p<.001). There were no recruitment differences in self-reported (p=.90) or biochemically confirmed smoking abstinence (p=.18). CONCLUSIONS: Compared to individuals recruited in-person, individuals recruited online were more educated, had higher health literacy, and presented with a different clinical profile (i.e., more likely to have CIN vs. cancer and to have completed active treatment). There were few differences in participant characteristics between recruitment approaches, and no differences on any smoking-related variables. Online recruitment has the potential to improve enrollment of cancer survivors to smoking cessation trials. IMPLICATIONS: People with a history of CIN or cervical cancer recruited to a smoking cessation RCT online (vs. in-clinic) were more likely to have a diagnosis of CIN vs. cancer and were more educated and health literate. Participants recruited online were more likely to be retained in the study and there were no differences in smoking abstinence rates at 12-months. Incorporating online recruitment increased the reach of tobacco treatment efforts to a larger and more diverse sample. This could reduce the burden of tobacco-related disease, improve CIN and cancer treatment outcomes, and reduce secondary malignancies and morbidity among this underserved group.

RESUMO

Despite the evidence of the disproportionate burden of tobacco use among people with HIV (PWH), little effort has been made to design and test smoking cessation interventions for PWH in resource-limited countries. We assessed the feasibility, acceptability, and preliminary effects of a video-based smoking cessation intervention consisting of eleven 3-8-minute sessions among PWH in Nepal, a lower-middle-income country. Guided by the phased-based model, our 3-month intervention focused on setting the quit date, smoking cessation, and abstinence maintenance. We screened 103 PWH over three weeks for our single-arm trial, with 53 considered eligible and 48 recruited (91%). Forty-six participants watched all video clips, while two watched 7-9. All participants were retained at a 3-month follow-up. The 1-week point prevalence abstinence (self-report supported with expired carbon monoxide levels < 5ppm) at 3-month follow-up was 39.6%. Most (90%) participants reported "very much" or "much" comfort with watching the videos on their smartphones, and all would recommend the intervention to other PWH who smoke. Overall, our pilot trial demonstrated the feasibility, acceptability, and high-level efficacy of the video-based smoking cessation intervention highlighting its potential for scaling up in Nepal and other resource-limited countries.

RESUMO

BACKGROUND: The prevalence of smoking among cervical cancer survivors is high and evidence-based smoking cessation interventions are critically needed. This paper describes the study design, methods, and data analysis plans for a randomized clinical trial (RCT) designed to evaluate the efficacy of a novel, personally tailored SMS-delivered text-based digital treatment adjuvant designed to enhance the long-term efficacy of a "Motivation And Problem-Solving" (MAPS) approach for smoking cessation among individuals with a history of cervical intraepithelial neoplasia (CIN) or cervical cancer. MAPS is a phone counseling approach designed to facilitate long-term abstinence that comprises 6 counseling calls over 12 months. The current trial is evaluating the efficacy of MAPS+, which comprises all MAPS components plus a 24-month digital treatment adjuvant. This trial represents a logical extension of our previous RCT, which compared the efficacy of MAPS to a quitline control condition and found that MAPS resulted in greater than a 2-fold increase in smoking abstinence at 12 months (i.e., 26.4% vs. 11.9%). This treatment effect was no longer significant at 18 months, suggesting that efficacy dissipated as time from the end of treatment increased. The primary aim of the current trial is to compare the efficacy of MAPS + and ST in facilitating long-term abstinence. METHODS: Individuals who smoke and have a history of cervical cancer or CIN (N = 340) are recruited throughout Florida and randomly assigned to Standard Treatment [ST] or MAPS+. ST participants are electronically connected with the Florida Quitline. MAPS + consists of 6 proactive MAPS-based counseling calls over 12 months plus the novel, personally tailored, text message-based treatment adjuvant delivered over 24 months. All participants receive 12 weeks of combination nicotine replacement therapy (patch and lozenge) and are followed for 24 months. Participant recruitment commenced in December 2022 and is ongoing. DISCUSSION: This study builds on promising results from our recent trial which found that MAPS was associated with substantially higher abstinence from smoking at the end of the 12-month treatment period. Finding that this low-burden, personally tailored digital treatment adjuvant improves the long-term efficacy of MAPS would have important clinical and public health implications.

RESUMO

PURPOSE: This study examined differences in Quitline treatment enrollment, engagement, and smoking cessation outcomes among primary care patients preferring Spanish and English using the evidence-based tobacco treatment Ask-Advise-Connect. METHODS: Ask-Advise-Connect was implemented April 2013 through February 2016 in a large safety-net health system to connect smokers with treatment via a link in the electronic health record. Rates of treatment enrollment, engagement, acceptance of nicotine replacement therapy, and smoking abstinence (self-reported and biochemically confirmed) were compared at 6 months among patients who received treatment in Spanish and English using χ 2 tests. Logistic regression examined language and nicotine replacement therapy and their interaction as predictors of abstinence. RESULTS: The smoking status of 218,915 patients was assessed and recorded in the electronic health record. Smoking prevalence was 8.4% among patients preferring Spanish and 27.0% among those preferring English. Spanish-preferring patients were less likely to enroll in treatment (10.7% vs 12.0%, χ 2 = 12.06, P = .001) yet completed more counseling calls when enrolled (median = 2 vs 1, P <.001). Patients who received treatment in Spanish (vs English) were twice as likely to be abstinent at 6 months (self-reported: 25.1% vs 14.5%, odds ratio [OR] = 1.98, 95% CI, 1.62-2.40; biochemically confirmed: 7.6% vs 3.7%, OR = 2.13, 95% CI, 1.52-2.97). Receipt of nicotine replacement therapy increased abstinence for all patients and language did not interact with nicotine replacement therapy to predict abstinence. CONCLUSIONS: Automated point-of-care approaches such as Ask-Advise-Connect have great potential to reach Spanish-preferring smokers. Those who received tobacco treatment in Spanish (vs English) demonstrated better engagement and cessation outcomes.

RESUMO

This mixed methods study aimed to evaluate the feasibility and preliminary efficacy of a fully automated, interactive smartphone-delivered intervention for smoking cessation among people living with HIV in Cambodia. We used the explanatory sequential design, with a pilot two-group single-blind randomized controlled trial (N = 50) followed by in-depth interviews with all trial participants. In the trial, participants were randomized to Standard Care (SC) or Automated Messaging (AM) group. SC comprised brief advice to quit and self-help materials. AM consisted of the SC components plus a fully automated smartphone-based treatment program that involved interactive and tailored proactive messaging for 2 months. Results showed that the AM approach was highly feasible and efficacious. Feasibility was supported by high rates of treatment engagement (e.g., 81% of delivered messages and assessments were read or completed) and high retention (96%) through the 2-month follow-up. Biochemically verified point prevalence abstinence at follow-up was 40% for the AM group and 8% for the SC group (relative risk: 5.0, 95% confidence interval: 1.2, 20.5). Being able to avoid other smokers, having coping skills, and having social/familial support contributed to successful abstinence. The AM program has the potential for wide-scale implementation in Cambodia and other low-income countries.

RESUMO

BACKGROUND: Smoking is the leading cause of preventable morbidity and mortality in the United States. Individuals with low socioeconomic status have disproportionately high smoking rates and greater difficulty quitting smoking. Efficiently connecting underserved smokers to effective tobacco cessation programs is crucial for disease prevention and the elimination of health disparities. Smartphone-based interventions have the potential to enhance the reach and efficacy of smoking cessation treatments targeting underserved smokers, but there is little efficacy data for these interventions. In this study, we will partner with a large, local hunger-relief organization to evaluate the efficacy and economic impact of a theoretically-based, fully-automated, and interactive smartphone-based smoking cessation intervention. METHODS: This study will consist of a 2-group randomized controlled trial. Participants (N = 500) will be recruited from a network of food distribution centers in West Central Florida and randomized to receive either Standard Treatment (ST, n = 250) or Automated Treatment (AT, n = 250). ST participants will be connected to the Florida Quitline for telephone-based treatment and will receive a 10-week supply of nicotine replacement therapy (NRT; transdermal patches and lozenges). AT participants will receive 10 weeks of NRT and a fully-automated smartphone-based intervention consisting of interactive messaging, images, and audiovisual clips. The AT intervention period will span 26 weeks, with 12 weeks of proactive content and 26 weeks of on-demand access. ST and AT participants will complete weekly 4-item assessments for 26 weeks and 3-, 6-, and 12-month follow-up assessments. Our primary aim is to evaluate the efficacy of AT in facilitating smoking abstinence. As secondary aims, we will explore potential mediators and conduct economic evaluations to assess the cost and/or cost-effectiveness of ST vs. AT. DISCUSSION: The overall goal of this project is to determine if AT is better at facilitating long-term smoking abstinence than ST, the more resource-intensive approach. If efficacy is established, the AT approach will be relatively easy to disseminate and for community-based organizations to scale and implement, thus helping to reduce tobacco-related health disparities.

RESUMO

Both inflammation and smoking are independent predictors of morbidity and mortality among people living with HIV (PLHIV). As smoking burden is likely to exacerbate inflammation, we tested the hypothesis that higher intensity and longer duration of smoking are positively associated with C-reactive protein (CRP, an inflammatory marker) among 284 PLHIV in Kathmandu, Nepal. We measured smoking status, intensity of smoking, smoking duration, and CRP concentrations. In total, 22.9% of never smokers, 24.3% former smokers, and 34.1% current smokers had high CRP (> 3 mg/l). The median intensity and duration of smoking were 12 (cigarettes/day) and 19 years, respectively. Intensity of smoking (beta for increase in number of cigarettes/day: ß = 0.245; p = 0.017), smoking duration (beta for 1-year increase in smoking: ß = 0.341; p = 0.013), and pack-years of smoking (beta for 1-pack-years of smoking increase: ß = 0.351; p = 0.002) were each positively associated with CRP concentrations. While quitting is important, reducing the intensity and duration of smoking until quitting might be helpful in reducing the levels of inflammation, thereby in mitigating HIV-related harms.

RESUMO

The use of antiretroviral therapy for people with HIV (PWH) has improved life expectancy. However, PWH now lose more life-years to tobacco use than to HIV infection. Unfortunately, PWH smoke at higher rates and have more difficulty maintaining abstinence than the general population, compounding their risk for chronic disease. In this Commentary, we describe a United States National Cancer Institute-led initiative to address the relative lack of research focused on developing, testing, and implementing smoking cessation interventions for PWH. This initiative supports seven clinical trials designed to systematically test and/or develop and test adaptations of evidence-based smoking cessation interventions for PWH (eg, combination of behavioral and pharmacological). We summarize each project, including setting/recruitment sites, inclusion/exclusion criteria, interventions being tested, and outcomes. This initiative provides critical opportunities for collaboration and data harmonization across projects. The knowledge gained will inform strategies to assist PWH to promote and maintain abstinence, and ensure that these efforts are adaptable and scalable, thereby addressing one of the major threats to the health of PWH. Reducing smoking behavior may be particularly important during the COVID-19 pandemic given that smokers who become infected with SARS-CoV-2 may be at risk for more severe disease. IMPLICATIONS: This Commentary describes a National Cancer Institute-led initiative to advance the science and practice of treating tobacco use among PWH, which is now responsible for more life years lost than HIV. We describe the scope of the problem, the objectives of the initiative, and a summary of the seven funded studies. Harmonization of data across projects will provide information related to treatment mediators and moderators that was not previously possible. Stakeholders interested in tobacco cessation, including researchers, clinicians and public health officials, should be aware of this initiative and the evidence-base it will generate to advance tobacco treatment among this high-risk population.

RESUMO

INTRODUCTION: Given that people living with HIV (PLWH) are disproportionately burdened by tobacco-related morbidity and mortality, it is critically important to understand the degree to which evidence-based cessation interventions are utilized by and are effective among PLWH. AIMS AND METHODS: This secondary data analysis aimed to examine differences in Quitline treatment enrollment and 6-month cessation outcomes among smokers seeking care at 1 HIV clinic and 12 non-HIV clinics that were part of a large healthcare system in the greater Houston, Texas metropolitan area, United States. Data were from a 34-month (April 2013-February 2016) one-group implementation trial that evaluated the Ask-Advise-Connect (AAC) approach to linking smokers with Quitline treatment. Primary outcomes included (1) treatment enrollment and (2) 6-month self-reported and biochemically confirmed abstinence. RESULTS: The smoking status of 218 915 unique patients was recorded in the electronic health record; 5285 (2.7%) of these patients were seen at the HIV clinic where the smoking prevalence was 45.9%; smoking prevalence at the non-HIV clinics was 17.9%. The proportion of identified smokers who enrolled in treatment was 10.8% at the HIV clinic and 11.8% at the non-HIV clinics. The self-reported abstinence rate was 18.7% among HIV clinic patients and 16.5% among non-HIV clinic patients. Biochemically confirmed abstinence was lower at 4.2% and 4.5%, respectively (all ps > .05). CONCLUSIONS: AAC resulted in rates of Quitline treatment enrollment and abstinence rates that were comparable among patients seen at an HIV clinic and non-HIV clinics. Findings suggest that AAC should be considered for widespread implementation in HIV clinics. IMPLICATIONS: PLWH were as likely as other patients to enroll in evidence-based tobacco cessation treatment when it was offered in the context of a primary care visit. Cessation outcomes were also comparable. Therefore, standard care for PLWH should include routine screening for smoking status and referrals to cessation treatment.

RESUMO

INTRODUCTION: By improving our understanding of the neurobiological mechanisms underlying addiction, neuroimaging research is helping to identify new targets for personalized treatment interventions. When trying to quit, smokers with larger electrophysiological responses to cigarette-related, compared with pleasant, stimuli ("C > P") are more likely to relapse than smokers with the opposite brain reactivity profile ("P > C"). AIM AND METHOD: The goal was to (1) build a classification algorithm to identify smokers characterized by P > C or C > P neuroaffective profiles and (2) validate the algorithm's classification outcomes in an independent data set where we assessed both smokers' electrophysiological responses at baseline and smoking abstinence during a quit attempt. We built the classification algorithm applying discriminant function analysis on the event-related potentials evoked by emotional images in 180 smokers. RESULTS: The predictive validity of the classifier showed promise in an independent data set that included new data from 177 smokers interested in quitting; the algorithm classified 111 smokers as P > C and 66 as C > P. The overall abstinence rate was low; 15 individuals (8.5% of the sample) achieved CO-verified 12-month abstinence. Although individuals classified as P > C were nearly 2.5 times more likely to be abstinent than smokers classified as C > P (12 vs. 3, or 11% vs. 4.5%), this result was nonsignificant, preliminary, and in need of confirmation in larger trials. CONCLUSION: These results suggest that psychophysiological techniques have the potential to advance our knowledge of the neurobiological underpinnings of nicotine addiction and improve clinical applications. However, larger sample sizes are necessary to reliably assess the predictive ability of our algorithm. IMPLICATIONS: We assessed the clinical relevance of a neuroimaging-based classification algorithm on an independent sample of smokers enrolled in a smoking cessation trial and found those with the tendency to attribute more relevance to rewards than cues were nearly 2.5 times more likely to be abstinent than smokers with the opposite brain reactivity profile (11% vs. 4.5%). Although this result was not statistically significant, it suggests our neuroimaging-based classification algorithm can potentially contribute to the development of new precision medicine interventions aimed at treating substance use disorders. Regardless, these findings are still preliminary and in need of confirmation in larger trials.

RESUMO

BACKGROUND: Smartphone apps for smoking cessation could offer easily accessible, highly tailored, intensive interventions at a fraction of the cost of traditional counseling. Although there are hundreds of publicly available smoking cessation apps, few have been empirically evaluated using a randomized controlled trial (RCT) design. The Smart-Treatment (Smart-T2) app is a just-in-time adaptive intervention that uses ecological momentary assessments (EMAs) to assess the risk for imminent smoking lapse and tailors treatment messages based on the risk of lapse and reported symptoms. OBJECTIVE: This 3-armed pilot RCT aimed to determine the feasibility and preliminary efficacy of an automated smartphone-based smoking cessation intervention (Smart-T2) relative to standard in-person smoking cessation clinic care and the National Cancer Institute's free smoking cessation app, QuitGuide. METHODS: Adult smokers who attended a clinic-based tobacco cessation program were randomized into groups and followed for 13 weeks (1 week prequitting through 12 weeks postquitting). All study participants received nicotine patches and gum and were asked to complete EMAs five times a day on study-provided smartphones for 5 weeks. Participants in the Smart-T2 group received tailored treatment messages after the completion of each EMA. Both Smart-T2 and QuitGuide apps offer on-demand smoking cessation treatment. RESULTS: Of 81 participants, 41 (50%) were women and 55 (68%) were white. On average, participants were aged 49.6 years and smoked 22.4 cigarettes per day at baseline. A total of 17% (14/81) of participants were biochemically confirmed 7-day point prevalence abstinent at 12 weeks postquitting (Smart-T2: 6/27, 22%, QuitGuide: 4/27, 15%, and usual care: 4/27, 15%), with no significant differences across groups (P>.05). Participants in the Smart-T2 group rated the app positively, with most participants agreeing that they can rely on the app to help them quit smoking, and endorsed the belief that the app would help them stay quit, and these responses were not significantly different from the ratings given by participants in the usual care group. CONCLUSIONS: Dynamic smartphone apps that tailor intervention content in real time may increase user engagement and exposure to treatment-related materials. The results of this pilot RCT suggest that smartphone-based smoking cessation treatments may be capable of providing similar outcomes to traditional, in-person counseling.

RESUMO

BACKGROUND: The prevalence of cigarette smoking is significantly higher among those living at or below the federal poverty level. Cell phone-based interventions among such populations have the potential to reduce smoking rates and be cost-effective. METHODS: We performed a cost-effectiveness analysis of three smoking cessation interventions: Standard Care (SC) (brief advice to quit, nicotine replacement therapy and self-help written materials), Enhanced Care (EC) (SC plus cell phone-delivered messaging) and Intensive Care (IC) (EC plus cell phone-delivered counselling). Quit rates were obtained from Project ACTION (Adult smoking Cessation Treatment through Innovative Outreach to Neighborhoods). We evaluated shorter-term outcomes of cost per quit and long-term outcomes using cost per quality-adjusted life year (QALY). RESULTS: For men, EC cost an additional $541 per quit vs SC; however, IC cost an additional $5232 per quit vs EC. For women, EC was weakly dominated by IC-IC cost an additional $1092 per quit vs SC. Similarly, for men, EC had incremental cost-effectiveness ratio (ICER) of $426 per QALY gained vs SC; however, IC resulted in ICER of $4127 per QALY gained vs EC. For women, EC was weakly dominated; the ICER of IC vs SC was $1251 per QALY gained. The ICER was below maximum acceptable willingness-to-pay threshold of $50 000 per QALY under all alternative modelling assumptions. DISCUSSION: Cell phone interventions for low socioeconomic groups are a cost-effective use of healthcare resources. Intensive Care was the most cost-effective strategy both for men and women.

RESUMO

OBJECTIVES: Intravaginal practices (IVPs) include washing, wiping, or inserting something inside the vagina. This study investigates the associations between IVPs and genital human papillomavirus (HPV) infection. METHODS: We conducted a cross-sectional study of 200 female sex workers aged 18 to 35 years in Phnom Penh, Cambodia. From August to September 2014. Data on sociodemographic characteristics, IVPs, and other behaviors were collected through face-to-face interviews. Self-collected cervicovaginal specimens were tested for 37 HPV genotypes. RESULTS: Multivariable Poisson regression models showed that a lower number of infecting HPV genotypes were associated with intravaginal washing in the past 3 months (incident rate ratios [IRR] = 0.65, 95% confidence interval [CI]: 0.46-0.94) and often performing intravaginal washing shortly after sex (IRR = 0.89, 95% CI: 0.81-0.99). Intravaginal washing before vaginal sex, intravaginal wiping, and intravaginal insertion were not associated with HPV infection. CONCLUSION: These findings challenge the existing view that all types of vaginal cleansing are harmful. Specifically, intravaginal washing shortly after sex (mainly with water) may help prevent HPV infection in female sex workers, who have several partners and thus frequently expose to sources of HPV infection with different genotypes.

RESUMO

Background: Efforts are needed to ensure that smokers with lower health literacy are provided with understandable and impactful information about the health consequences of smoking and benefits of quitting. Purpose: To test the influence of health literacy on smokers' responses to health risk messages manipulated on framing (gain vs. loss) and emotionality (factual vs. emotional). Methods: Participants (N = 402) were randomized to evaluate one of four sets of smoking risk messages (factual gain-framed, factual loss-framed, emotional gain-framed, or emotional loss-framed). Multiple linear regressions examined main effects of health literacy, message emotionality, and message framing on: (a) risk perceptions, (b) behavioral expectations (i.e. cut down, limit, quit), and (c) risk knowledge. Two-way interactions of health literacy with emotionality and framing were examined for these outcomes. Analyses were based on theory-driven, a priori hypotheses. Results: As hypothesized, main effects emerged such that smokers with higher health literacy reported stronger risk perceptions and knowledge retention regardless of message type. Additionally, emotional (vs. factual) and gain- (vs. loss-) framed messages were associated with certain lower risk perceptions regardless of health literacy level. Consistent with hypotheses, two-way crossover interactions emerged between health literacy and emotionality. Among smokers with higher health literacy, factual messages produced higher perceived risk and stronger expectations for quitting. Among smokers with lower health literacy, emotional messages produced higher perceived risk and stronger expectations for quitting. Conclusions: Health literacy plays an important role in influencing how smokers respond to different risk messages. One's health literacy should be considered when determining whether risk communications emphasize factual or emotional content.

RESUMO

Introduction: Tobacco use among persons living with HIV represents an important risk factor for poor treatment outcomes, morbidity, and mortality. Thus, efforts designed to inform the development of appropriate smoking cessation programs for this population remains a public health priority. To address this need, a study was conducted to longitudinally assess the relationship between intention to quit smoking and cessation over the 12-month period following initiation of HIV care. Methods: Patients initiating HIV care at a large inner city safety net clinic were enrolled (n = 378) in a 12-month prospective study. Audio computer-assisted self-interviews were conducted at baseline, and at 3, 6, 9, and 12 months post-enrollment, and HIV-related clinical data were collected from participants' electronic medical records. Variables of interest included intention to quit smoking, 7-day point prevalence smoking abstinence (biochemically verified), and stage of HIV. Data were collected in Houston, Texas from 2009 to 2015. Results: The sample was 75% male and 62% Black. Findings indicated that intention to quit smoking increased between baseline and 3 months, and subsequently trended downward from 3 to 12 months. Results from linear and generalized linear mixed models indicated that participants with advanced HIV disease (vs. not advanced) reported significantly (p < .05) higher intention to quit smoking at 3, 6, and 12 months post-study enrollment. A similar though nonsignificant pattern was observed in the smoking abstinence outcome. Conclusions: HIV treatment initiation appears to be associated with increases in intention to quit smoking thus serves as a potential teachable moment for smoking cessation intervention. Implications: This study documents significant increases in intention to quit smoking in the 3-month period following HIV care initiation. Moreover, quit intention trended downward following the 3-month follow-up until the 12-month follow-up. In addition, a marked effect for HIV disease stage was observed, whereby participants with advanced HIV disease (vs. those without) experienced a greater increase in intention to quit. HIV treatment initiation appears to be associated with increases in intention to quit smoking, thus serves as a crucial teachable moment for smoking cessation intervention for people living with HIV.

RESUMO

BACKGROUND: This study investigated the prevalence of and risk factors for oral human papillomavirus (HPV) infection with multiple genotypes in the United States. METHODS: Data were from the nationally representative 2009-2012 National Health and Nutrition Examination Survey. This analysis comprised 9257 participants for whom data on oral HPV (37 genotypes) and associated risk factors were available. RESULTS: The weighted prevalence of multitype (2-6 types) oral HPV infection was 1.5% (2.5% for men, 0.4% for women) in the whole sample and 19.7% (22.0% for men, 12.1% for women) in those who had any type of oral HPV positivity. Most multitype oral HPV cases (83.8%) harbored one or more oncogenic types. In the adjusted multinominal logistic regression model, being male (relative risk ratio [RRR] = 3.69; 95% confidence interval [CI], 1.57-8.65), being a current cigarette smoker (RRR = 2.57; 95% CI, 1.23-5.36), and having a new sex partner in the past year (RRR = 2.10; 95% CI, 1.03-4.28) were associated with an increased risk of multitype oral HPV infection over single-type HPV infection. CONCLUSIONS: Men, smokers, and those who had new sexual partners were at a significantly higher risk for multitype oral HPV infection.

RESUMO

BACKGROUND: Engaging young adults for the purpose of communicating health risks associated with nicotine and tobacco use can be challenging since they comprise a population heavily targeted with appealing marketing by the evolving tobacco industry. The Food and Drug Administration seeks novel ways to effectively communicate risks to warn about using these products. This paper describes the first step in developing a text messaging program delivered by smartphones that manipulate three messaging characteristics (i.e., depth, framing, and appeal). METHODS: Perceptions of community college students were described after previewing text messages designed to inform about risks of using conventional and new tobacco products. Thirty-one tobacco users and nonusers, aged 18-25 participated in five focus discussions held on two community college campuses. Attendees reviewed prototype messages and contributed feedback about text message structure and content. Qualitative data were coded and analyzed using NVivo Version 10. RESULTS: Most participants were female and two-thirds were ethnic minorities. A variety of conventional and new tobacco products in the past month were used by a third of participants. Three identified domains were derived from the qualitative data. These included perceived risks of using tobacco products, receptivity to message content, and logistical feedback regarding the future message campaign. CONCLUSION: Overall, participants found the messages to be interesting and appropriate. A gap in awareness of the risks of using new tobacco products was revealed. Feedback on the prototype messages was incorporated into message revisions. These findings provided preliminary confirmation that the forthcoming messaging program will be appealing to young adults.

RESUMO

BACKGROUND: Smoking rates among people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS; PLWHA) are at least twice as high as rates in the general population. Consistent with the reciprocal model of pain and smoking, PLWHA with pain who smoke may use smoking as a means of coping with pain, thus presenting a potential barrier to quitting. The aim of this study is to better understand how pain relates to smoking cessation among 474 HIV-positive adults enrolled in a cell phone-delivered smoking cessation trial. METHODS: Participants were randomly assigned to usual care (cessation advice and self-help materials) or 11 sessions of cell phone-delivered smoking cessation treatment. Pain, as assessed by the Medical Outcomes Study-HIV Health Survey (MOS-HIV), and point prevalence abstinence were collected at the 3-month treatment end and at 6- and 12-month follow-ups. Self-reported abstinence was biochemically verified by expired carbon monoxide (CO) level of <7 ppm. RESULTS: Using multilevel modeling for binary outcome data, the authors examined the relationship between pain and abstinence, from treatment end through the 12-month follow-up. Consistent with the authors' hypothesis, less pain was associated with greater likelihood of 24-hour (ß = .01, t(651) = 2.53, P = .01) and 7-day (ß = .01, t(651) = 2.35, P = .02) point prevalence abstinence, controlling for age, gender, baseline pain, nicotine dependence, and treatment group. No pain × treatment group interaction was observed. CONCLUSIONS: These results can help us to better identify PLWHA at greater risk for relapse in smoking cessation treatment. Future research may examine the effectiveness of more comprehensive smoking cessation treatment that incorporates aspects of pain management for PLWHA who smoke and have high pain and symptom burden.

RESUMO

Anxiety sensitivity is the fear of anxiety-related sensations and subjective social status is a self-perception of social standing relative to others: both constructs have been linked to psychological symptomatology. This study investigated the interactive effects of anxiety sensitivity and social status in relation to anxiety and depressive symptomatology expression among 124 black adults. Participants provided sociodemographics and completed self-report questionnaires. The interactive associations between anxiety sensitivity and social status on anxiety symptomatology and depressive symptomatology were examined with hierarchical linear regressions adjusted for sociodemographics and negative affectivity. Significant interactions between anxiety sensitivity and social status were evident only for anxiety symptoms: specifically, the association between anxiety sensitivity and anxiety symptoms was much stronger for individuals with lower (versus higher) subjective social status. Black adults with this higher anxiety sensitivity/lower social status phenotype may be at heightened risk for the expression of anxiety symptomatology, and may benefit from interventions to reduce anxiety sensitivity.

RESUMO

OBJECTIVES: Quality of Life (QoL) at baseline is frequently found to be a prognostic factor in cancer studies. However, little is known about the relationship of the trajectory of QoL and survival in patients with advanced cancer. This study evaluates the effects of both level and change of QoL on survival to explore the potential of utilizing longitudinal information of QoL for prognosis. METHODS: A series of joint models were used in a sample (N = 512) of patients diagnosed with advanced cancer (sample consisted of nine different cancer sites) with assessments of QoL across six time points and with survival information recorded up to 28 months after diagnosis. We used FACT-G as the QoL measure, and we evaluated the effects of change in QoL controlling for the time-dependent effects of chemotherapy and radiation. RESULTS: The median survival for patients was 14.2 months, and 10% of the sample had survived beyond 28 months after the diagnosis of advanced cancer. The effect of change of QoL on survival was significant (hazard ratio = 0.98; p < 0.001) controlling for time-dependent treatment effects. Also, the slope of the trajectory in QoL was found to be a significant predictor of survival (hazard ratio = 0.18; p < 0.001). CONCLUSION: These preliminary findings suggest that the patient's longitudinal experience in QoL may be a significant prognostic factor of survival, a novel finding with potentially important implications in medical decision making. Longitudinal information on QoL can be used for updating the patient's prognosis of survival.
