HIV What We Know About HIV+ Smokers Implications for Treatment Jack Burkhalter, Ph.D. Smoking Cessation Program Memorial Sloan-Kettering Cancer Center HIV Acknowledgments Support: NYS HRI 656-03-FED awarded to The AIDS Institute, NYS Dept. of Health Resources and Services Administration under the Special Projects of National Significance Program Colleagues: Carolyn Springer, Ph.D., Adelphi University Rosy Chhabra, Psy.D., Yeshiva University Jamie Ostroff, Ph.D., Memorial Sloan-Kettering Cancer Ctr. Bruce Rapkin, Ph.D., Memorial Sloan-Kettering Cancer Ctr. HIV Approach to this talk Evidence-based, with the state of current knowledge Clinical researcher’s perspective Cancer prevention perspective HIV HIV and Smoking: Why now? Improved life expectancy in HIV disease Increasing interest in health behaviors that affect length and quality of life Growing research that links smoking to increased health risks for PLWHIV Recent studies indicating very high rates of tobacco use among PLWHIV HIV Comparisons of Smoking Rates Population Smoking Rate U.S. General Females Males U.S. Medicaid patients 22.1% 20.3% 24.8% 36.0% HIV+ National samples 45-51% HIV+ Outpatient clinics 47-72% Sources: CDC, 2001; 2004; Collins et al., 2001; Turner et al., 2001; Gritz, et al., 2004; Mamary, et al., 2002; Niaura et al., 1999 What are the health risks of smoking for HIV+ persons? ↑ Risk of oral thrush and oral hairy leukoplakia ↑ Risk of community-acquired pneumonia, emphysema, spontaneous pneumothorax, and bronchial hyperresponsiveness (indicator of asthma) ↑ Risk of cryptococcosis ↑ Incidence of periodontal disease and oral lesions ↑ Lung, lip, and anal cancer, in addition to AIDS-defining cancers (Kaposi Sarcoma, non-Hodgkin lymphoma, and invasive cervical cancer) What we don’t know for sure- Cannot conclude that smoking promotes progression in HIV disease Although smoking negatively affects SOME aspects of immune system, this has not been linked with AIDS onset or mortality More research needed HIV Two Published Studies Gritz et al.

NY assessed by asking if they had used too much alcohol in past 3 months 3Texas assessed for any illicit drug use in last 30 days; NY assessed for any illicit drug use in past 3 months Texas Findings Current smokers vs. nonsmokers (former + never) more likely to be: – – – – White non-Hispanic Older (vs. 20-29 years) Have lower education (< high school) Heavy drinkers of alcohol Quitters (vs. current smokers) more likely to: – Be White (vs. Black, p<.06) – Have higher education – Not be heavy drinkers of alcohol New York Findings Current smokers vs. nonsmokers (vs. former + never) more likely to report: – Greater lifetime illicit drug use – Greater current illicit drug use – Less bodily pain Quitters (vs. current smokers) more likely to: – Perceive greater health risks of smoking – Not currently use illicit drugs – Report more bodily pain (p<.10) NY Study What affects readiness to quit smoking? Lower readiness to quit smoking associated with: – Greater current illicit drug use – Greater emotional distress – Lower number of quit attempts since HIV diagnosis Other Indicators of Readiness to Quit Smoking Advised by a healthcare provider to quit smoking Would use a “low cost or free” smoking cessation program Smokers who had not attempted to quit since HIV diagnosis Former smokers who quit after HIV diagnosis Former smokers who quit within 1 year of diagnosis 81% 46% 35% 77% 14% Perceived risks of smoking “How much do you believe that there are health risks associated with quitting smoking?” Not at all A little bit Somewhat Quite a bit Very much 1 2 3 4 5 Current smokers 3.8* *p<.001 Former smokers 4.5* What health risks do you believe smoking exposes you to?

Enhancing Motivation to Quit: The “5 R’s” Relevance: Why quitting is personally relevant. Be specific. Risks: Identify acute (shortness of breath), long-term (emphysema), and environmental risks (increased heart disease for family) •Rewards: Identify benefits (e.g., lower risk of oral thrush, improved breathing) •Roadblocks: Identify barriers to quitting (e.g.,substance use) •Repetition: Repeat motivational intervention every time client visits Source: USDHHS Clinical Practice Guidelines: Treating Tobacco Use and Dependence, 2000 “Teachable Moments” HIV diagnosis Respiratory events, symptoms, diagnoses – PCP or bacterial pneumonia – Symptoms such as shortness of breath, chronic cough – Bronchitis • Oral conditions, such as thrush, OHL • Any concerns about health or well-being Personalizing Risks & Benefits Intrinsic motivation (health concerns) is related to quitting success Extrinsic motivation (social pressure to quit) is not as powerful as intrinsic motivation Identify each person’s specific benefits in cessation and educate them about benefits unknown to them – “You complain of shortness of breath; giving up cigarettes will improve your breathing and stamina.” Do the same for risks of continued smoking: – “Your risk for oral thrush and bacterial pneumonia are higher.” Systems Level Interventions Regular contact with healthcare providers offers many opportunities to: Ask Advise Assess willingness to quit Assist Arrange for follow-up Discuss NYS Medicaid coverage for treatment of tobacco dependence, cost Comprehensive Care Comprehensive treatment needed for prevalence of substance abuse, depression, and smoking among PLWHIV Integrate services for maximum uptake, reinforcement of adherence, and continuity of care Tobacco use should be treated seriously as a significant health threat What to treat first? So many problems, so few resources Treating depression, anxiety, alcohol or substance abuse, nonadherence to HIV meds—where to begin? Can PLWHIV change more than one health behavior at a time? What about motivation to change? Tobacco use assessment and treatment may be an opening to address other problems as well Queens Quits! • Our mission is to promote tobacco prevention and cessation among the residents of Queens County. To provide training and technical assistance to enhance readiness and capacity of Queens-based physicians, dentists and other health care providers to deliver brief tobacco cessation interventions in clinical practice. To increase the number of Queens residents who are referred for intensive cessation counseling, cessation pharmacotherapy and use the services of the NYS QuitLine. Funded by a Tobacco Cessation Center Grant from the NYS DOH Tobacco Control Program. Let’s work together! Health care clinicians, advocates, service providers, researchers, policy makers Reduce smoking prevalence among HIV+ persons through education, research, and HIV care that targets tobacco use Improve the quality and length of life of those living with HIV For more HIV-related resources, please visit www.hivguidelines.org
