Tobacco smoking in HIV-infected persons. Patrick Peretti-Watel Inserm (French National Institute of Health and Medical Research) Tobacco smoking in HIV-infected persons. I. Medical & epidemiological background. II. Cigarette smoking: a sociological approach. III. Why do HIV-infected people smoke? I. Medical & epidemiological background.
Today, PLWHAs live longer Thanks to antiretroviral treatments (ART) since 1996; but many of them smoke tobacco Smoking prevalence: 40-70% >> general population + higher levels of nicotine dependence; and smoking is especially harmful to PLWHAs CVDs and (lung) cancers became major causes of mortality in this population. HIV-infected smokers lose more life-years to smoking than to HIV (Helleberg et al., 2013, Clin Infect Dis)
I.1. Many PLWHAs smoke tobacco (1/7) PLWHAs smoke much more than the general population comparing smoking prevalence according to serostatus requires first (at least) gender & age standardisation. HIV-infected people is a very heterogeneous category, merging very contrasted profiles, including for smoking prevalence. Health Barometer survey, general population aged 18-85, 2010, N=25,034 (INPES); VESPA2 survey, national & representative survey, PLWHAs living in France, 18-88, 2011, N=3,022 (ANRS). I.1. Many PLWHAs smoke tobacco (2/7)
Health Barometer: 31% of smokers, mean age 48, 49% of men. VESPA2 survey: 38% of smokers, mean age 47, 67% of men. Among VESPA2 participants: -people infected through homosexual intercourse (36%): 42% of smokers, mean age 48, 100% of men. -people infected through intravenous drug use (10%): 78% of smokers, mean age 49, 70% of men. -people infected through heterosexual intercourse (47%): 26% of smokers, mean age 46, 41% of men. I.1. Many PLWHAs smoke tobacco (3/7) Smoking prevalence by gender and age for HIV-infected people and the general population, France, INPES 2010-ANRS 2011. 90%

I.1. Many PLWHAs smoke tobacco (7/7) When compared to the general population, the smoking prevalence is higher among PLWHAs infected through homosexual intercourse, and much more higher among those infected through intravenous drug use. See also: I.2. Smoking is especially harmful to PLWHAS (1/4)
Among PLWHAs, smoking increases the risk of: CVDs, non-AIDS cancer, but also pneumocystis pneumonia, bacterial pneumonia, chronic obstructive pulmonary disease, oral candidiasis, emphysema, hairy leukoplakia... +ART side-effects / CVDs & cancer. ART & AIDS: smoking immune system impairment, increase in HIV replication, decreasing response to ART virologic failure and disease progression. Behavioural & attitudinal outcomes: HIV-infected smokers report lower medical adherence, attend fewer medical visits, and rank health as less important to
their quality of life... I.2. Smoking is especially harmful to PLWHAS (2/4) Behavioural & attitudinal outcomes: a focus on adherence to treatment & drug use. Measuring independent effects for each drug use on adherence led to mixed and contradictory results. I.2. Smoking is especially harmful to PLWHAS (3/4) VESPA survey 2003 (n=2484): investigating the relationships between drug use (cigarette, alcohol, cannabis, cocaine, heroin,
drug maintenance treatment) & adherence to HAART. Two strategies: #1: assessing independent effects for each drug use separately; #2: first identifying patterns of drug uses with a cluster analysis, and assessing independent effects for each pattern separately. #1 cigarette smoking predictive of low adherence, no significant effect for cocaine or heroin use. #2 among other patterns, we found a multiple addictions profile (heroin+cocaine+DMT+tobacco) strongly associated to low adherence. I.2. Smoking is especially harmful to PLWHAS (4/4) Cigarette smoking should not be considered as an
independent risk factor, it is usually embedded in a lifestyle and connected with other behaviours/habits. First step toward a sociological approach of cigarette smoking. II. Cigarette smoking: a sociological approach. II.1. Three basic principles of sociology. II.2. Cigarette smoking as a social practice. II.3. Smokers motives and justifications. II.4. The social differentiation of smoking. II.1. Three basic principles of sociology.
Situated/limited rationality: people pursue objectives, under specific circumstances, constraints, that must be understood. Reflexivity: people are able/prone to stand back from their own experience to engage in reflexive thinking, in order to describe/explain/justify what they do in-depth interviews Social groups: people are not isolated atoms in a
vacuum. Their behaviours, attitudes and beliefs are constructed collectively, are influenced by their social environment peers/colleagues/relatives with similar living conditions and values. II.2. Cigarette smoking as a social practice. (1/3) Not (only) a chronic, addictive and contagious disease: tobacco pandemic, behavioural epidemic through peer pressure/imitation & nicotine addiction medicalization of
smoking. Considering cigarette smoking as a social practice implies a radical departure from this perspective. We have to consider various aspects of cigarette smoking: implicit rules, know-how, meanings and motives... These aspects are not personal attributes: they are shared with and learned from other smokers, and they change across time and space... II.2. Cigarette smoking as a social practice. (2/3) Social practice learning process. - how to hold the cigarette correctly, - how to inhale/exhale properly,
- how to use tobacco as a psychological tool (as a sedative to alleviate stress, as a stimulant to counter boredom), - implicit rules: in which circumstances, in which places, with which people, it is acceptable or not to smoke, or to ask for a cigarette... II.2. Cigarette smoking as a social practice. (3/3) - II.3. Smokers motives and justifications. (1/4) Smokers motives and justifications.
Multiple benefits from smoking: feeling of membership, social bonding, relaxation, pleasure, dealing with periods of boredom/stress/sadness, regulating ones weight... These motives depend on personal smoking history, gender, age, socioeconomic status... II.3. Smokers motives and justifications. (2/4) Most common motives: Reported reasons for smoking, from 1 (never) to 10 (always). II.3. Smokers motives and justifications. (3/4) Examples of justifications:

Main risk denial beliefs among French smokers: (Cancer Barometer survey, 2010, N=1,106 smokers, INPES) Human beings are argumentative rather than strictly rational. They are prone to convincing self-delusion. Most smokers are neither ignorant of risk nor seeking it purposely. But they find good reasons to deny/minimize it. Of course, they can be wrong. But taking this risk denial into consideration is necessary to improve prevention. II.4. The social differentiation of smoking.
(1/5) Cigarette smoking, considered as a social practice, involves a whole set of beliefs, attitudes & behaviours, acquired through a learning process embedded in social context. One important corollary: social differentiation of smoking-related beliefs, attitudes and behaviours, & social differentiation of sensitivity to prevention. Example: trends in smoking prevalence in France during the
2000s ( anti-tobacco policies & social differentiation of smoking prevalence). II.4. The social differentiation of smoking. (2/5) (40-45)/ 45= -11% (28-36)/36= -22% II.4. The social differentiation of smoking.
(3/5) Why are low-SES people more prone to smoke/less likely to quit? Low-SES smokers are more prone to use cigarette as a coping mechanism (to relieve stress, to take their mind off their cares and worries) they regard cigarettes as a basic essential /one of their last few pleasure Facing increasing cigarettes prices, they try to reduce the cost of their smoking habit, not to quit or to reduce their consumption.

40% 50% 60% In multivariate analysis present-orientation remained a significant risk factor for current smoking (after adjustment on sociodemographic profile, transmission group). III.2. Motives, justifications & time horizon. (7/7)
HIV-infected smokers motives and justifications: -as other smokers, they frequently portray themselves as rational beings assessing the costs and benefits of smoking; - regarding other smokers, they also share the same motives (facilitating social interaction, stress relief) and justifications (compensatory measures: exercise), - but some motives and risk denial beliefs are more specific to HIV (stress due to HIV, lack of confidence toward physicians, dealing with symptoms or side-effects of treatment, relativization because of HIV, shortened time-horizon due to HIV); their priority is HIV now and they think that smoking helps them to cope with stress and to stay mentally positive now.

(2/2) Conclusion. Smoking is a social practice that involves a whole set of beliefs, attitudes and behaviours, embedded in social context. Social differentiation of smoking and prevention efficacy, including among HIV-infected smokers. HIV-infected smokers have both common and specific motives & justifications. To make them quit, it is necessary to convince them that its worth it.
