Cigarette Smoking in Persons Living with Hepatitis C: The National Health and Nutrition Examination Survey (NHANES), 1999-2014.

ABSTRACT: BACKGROUND:Cigarette smoking is common in persons living with hepatitis C (hepatitis C+), but national statistics on this harmful practice are lacking. A better understanding of smoking behaviors in hepatitis C+ individuals may help in the development of targeted treatment strategies. METHODS:We extracted data from the National Health and Nutrition Examination Survey (NHANES) between 1999 and 2014. Hepatitis C+ were compared with hepatitis C- adults in the entire sample and in the subset of current smokers. Measures included demographics, current smoking, cigarettes/day, nicotine dependence, other tobacco use, substance use, and medical and psychiatric comorbidities. RESULTS:Complete smoking and hepatitis C virus (HCV) data were available for 39,472 (90.1%) of 43,793 adult participants in NHANES during the study years. Hepatitis C+ smoked at almost triple the rate of hepatitis C- adults (62.4% vs 22.9%), with no significant difference between hepatitis C+ men and women (64.5% vs 58.2%). Hepatitis C+ smokers were more likely to smoke daily than hepatitis C- smokers (87.5% vs 80.0%), but had similar levels of nicotine dependence. Hepatitis C+ smokers were more likely to be older (mean age: 47.1 vs 41.5 years), male (69.4% vs 54.4%), Black (21.2% vs 12.1%), less educated (any college: 31.8% vs 42.9%), poor (mean family monthly poverty index: 1.80 vs 2.47), uninsured (43.9% vs 30.4%), use drugs (cocaine: 11.1% vs 3.2%; heroin: 4.0% vs 0.6%), and be depressed (33.2% vs 13.5%). Multivariate analyses revealed significant associations of both hepatitis C infection and cigarette smoking with current depression and hypertension. CONCLUSIONS:There is a cigarette smoking epidemic embedded within the hepatitis C epidemic in the United States. The sociodemographic profile of hepatitis C+ smokers suggests that the implementation of effective tobacco treatment will be challenging. Thoughtful treatment strategies that are mindful of the unique characteristics of this group are needed.

Project description:INTRODUCTION:Population-based studies show inconsistent effects of cigarette smoking on olfactory function. We aimed to identify direct and indirect associations between measures of smoking exposure/nicotine dependence and altered olfaction in a nationally representative sample of adults. METHODS:NHANES 2011-2014 (n = 7418) participants (mean age = 57.8 ± 12.2 years) self-reported olfaction and related health and demographic risks. Affirmative answers to three questions defined altered olfaction (olfactory problems in the past years; worse ability since age 25; phantom smells). Smoking (never, former, current) was self-reported by chronicity (pack years, PY) and dependency (time to first cigarette upon waking) and verified by serum cotinine. Associations were tested with logistic regression, reporting odds ratios (ORs) and 95% confidence intervals (CIs), and mediation models. RESULTS:Estimated prevalence of altered olfaction was 22.3%, with age-related increases. Nearly half of the sample were former/current smokers (47.4%). Controlling for olfactory-related risks, ≥10 PY smokers had significantly greater odds of altered olfaction versus never smokers (OR 1.36, CI: 1.06-1.74). The odds of altered olfaction were heightened among current smokers (≥10 PY) who also had high nicotine dependence (smoked ≤30 min of waking) (OR 1.41, CI: 1.01-1.99). Light smokers (≤10 PY smokers) did not show increased odds versus never smokers. Current smokers who also were heavy drinkers (≥4 drinks/day) had the highest odds for altered olfaction (OR 1.96, CI: 1.20-3.19). Olfactory-related pathologies (sinonasal problems, serious head injury, tonsillectomy, xerostomia) partially mediated the association between smoking and altered olfaction. CONCLUSIONS:Chronic cigarette smoking was associated with increased odds of self-reported olfactory alterations, directly and indirectly via olfactory-related pathologies. IMPLICATIONS:Analysis of the US nationally representative data revealed significant positive associations between chronic smoking and alterations in the sense of smell. Rates of smell alteration (self-reported problems in the past year, losses with aging, and phantom smells) increased from 23% among adults to 33% for chronic smokers and 38% for chronic smokers who also reported heavy drinking. Chronic smoking showed associations with smell alteration that were direct and indirect through exposure to olfactory-related pathologies (naso-sinus problems, dry mouth, head/facial injury). Smell alteration can impact smokers' quality of life by challenging the ability to sense warning odors, food flavor, and olfactory-stimulated emotions and memories.

Project description:ObjectiveApproximately one in four deaths among people living with HIV (PLWH) in the United States can be attributed to cigarette smoking. Using a nationally representative sample of PLWH, this study examines the prevalence, time-trends, and correlates of current cigarette smoking among PLWH compared to people without HIV.DesignSecondary analysis of population-based cross-sectional biobehavioral survey.MethodsData were pooled from the 1999-2016 National Health and Nutrition Examination Survey (NHANES). All adults (20-59 years) who self-reported their smoking status and were tested for HIV (HIV+ = 152; HIV- = 26 305) were included in the analysis. Prevalence with 95% confidence interval (95% CI), trend analysis by year and group (HIV+/HIV-), and multivariable logistic regression analyses were performed with the complex survey design adjustments.ResultsOverall, 47.0% of PLWH were current smokers compared to 25.5% of those without HIV. From 1999 to 2016, the decline in smoking in PLWH was comparable to those without HIV (10.7% vs. 8.0%). PLWH smokers were more likely than PLWH nonsmokers to be substance users (adjusted odds ratio [aOR] = 17.52; 95% CI = 2.04 to 27.8). Compared to smokers without HIV, PLWH smokers were more likely to be older (1.10; 1.06 to 1.14), males (7.96; 2.50 to 25.40), non-Hispanic Black (10.45; 4.13 to 26.45), with depression (Patient Health Questionnaire-9 sum score ≥5) (3.79; 1.22 to 11.79), and less likely to be gay (0.02; 0.00 to 0.07).ConclusionCigarette smoking among PLWH is a major public health problem in the United States. Targeted and tailored smoking cessation interventions that incorporate assessment and treatment of depression and co-occurring substance use are critical for PLWH, especially among those who are disproportionately affected by smoking and HIV (sexual minority).ImplicationsThis study offers important research implications in four areas:1. The decline in smoking among PLWH over 18 years has been modest, and half of PLWH are still smokers.2. More resources and efforts should be allocated to reduce cigarette smoking among PLWH.3. There is a critical need to develop and test culturally tailored smoking cessation interventions for minority subgroups who are most impacted by HIV infection and smoking (non-Hispanic Blacks and men who have sex with men)4. Smoking cessation interventions designed for PLWH should incorporate assessment and treatment of depression and substance use.
