A Longitudinal Analysis of Respiratory Illness and Tobacco Use Transitions.

ABSTRACT:

Introduction

Among individuals with chronic respiratory conditions, transitions between patterns of tobacco product use are not well understood. This study examines how transitions, including quitting altogether, differ over time between those who do and do not have chronic respiratory conditions.

Methods

Data from youth and adult participants of the longitudinal Population Assessment of Tobacco and Health Study (2013-2018) were analyzed. Youth aged 12-17 years were included if they had aged into the adult sample by Wave 4. Stratified polytomous regression models built under a first-order Markov assumption modeled the probability of transitioning between different states/patterns of tobacco product use (exclusive current E-cigarette use, exclusive current combustible tobacco product use, current dual use of combustible products and E-cigarettes, and no current tobacco product use) at each wave. Marginal transition probabilities were computed as a function of ever or past-year diagnosis of a respiratory condition (separately for asthma and a composite variable representing chronic bronchitis, emphysema, and/or chronic obstructive pulmonary disease). Analyses were conducted in 2020-2021.

Results

Most individuals, regardless of respiratory condition, maintained the same pattern of tobacco use between waves. Exclusive combustible tobacco product users, including those with or without a respiratory condition, were not likely to become exclusive E-cigarette users or to quit using tobacco entirely.

Conclusions

Although combustible tobacco use negatively impacts the management and prognosis of respiratory illnesses, combustible tobacco users who were recently diagnosed with a chronic respiratory condition were not likely to quit using tobacco. Efforts to encourage and support cessation in this medically vulnerable population should be increased.

Project description:BackgroundIn Southeast Asia, tobacco use is a major public health threat. Tobacco users in this region may switch between or concurrently use smoked tobacco and smokeless tobacco (SLT), which makes effective tobacco control challenging. This study tracks transitions of use among different product users (cigarettes, bidis, and SLT) in Bangladesh, one of the largest consumers of tobacco in the region, and examines factors related to transitions and cessation.MethodsFour waves (2009-2015) of the International Tobacco Control (ITC) Bangladesh Survey with a cohort sample of 3245 tobacco users were analysed. Generalized Estimating Equations (GEE) models were used to explore the socioeconomic correlates of transitions from the exclusive use of cigarettes, bidis, or SLT to the use of other tobacco products or quitting over time.FindingsAmong exclusive cigarette users, most remained as exclusive cigarette users (68.1%). However, rural smokers were more likely than urban smokers to transition to bidi use (odds ratio [OR] = 3.02, 95% confidence interval [CI] = 1.45-6.29); to SLT use (OR = 2.68, 95% CI = 1.79-4.02) and to quit tobacco (OR = 1.57, 95% CI = 1.06-2.33). Among exclusive bidi users, transitional patterns were more volatile. Fewer than half (43.3%) of the exclusive bidi users maintained their status throughout the waves. Those with higher socio-economic status (SES) were more likely to quit (OR = 4.16, 95% CI = 1.08-13.12) compared to low SES smokers. Exclusive SLT users either continued using SLT or quit with minimal transitions to other products (≤2%). Nevertheless, males were more likely to switch to other tobacco products; younger (OR = 2.94, 95% CI = 1.23-6.90 vs. older), more educated (OR = 1.55, 95% CI = 1.77-3.12 vs. less educated), and urban SLT users (OR = 0.52, 95% CI = 0.30-0.86 for rural vs. urban users) were more likely to quit.InterpretationComplex transitional patterns were found among different types of tobacco product users over time in Bangladesh. These findings can inform more comprehensive and multi-faceted approaches to tackle diversified tobacco use in Bangladesh and neighbouring countries in the Southeast Asia region with similar tobacco user profiles of smoked tobacco and SLT products.FundingThis is an unfunded observational study with the use the ITC Bangladesh datasets.

Project description:IntroductionSmokeless tobacco (SLT) use in the United States has remained constant or even increased slightly in recent years, whereas smoking has continuously decreased. Characterization of transitions between tobacco products is critical to understand the reasons behind the continuing use of smokeless tobacco.MethodsTwo longitudinal cohorts of Tobacco Use Supplement of the Current Population Survey (TUS-CPS), 2002-2003 (n = 14996) and 2010-2011 (n = 18226), were used to examine transitions between cigarette and SLT use over 1-year periods. Weighted population percentages of four use categories (exclusive cigarette use, exclusive SLT use, dual use, and neither) were calculated for different demographic groups. Transition between use categories and quit rates by product were calculated for each cohort.ResultsRelative to 2002-2003, smoking quit rates of male exclusive smokers significantly increased in 2010-2011 (11.6% vs. 24.4%, p < .0001), but the corresponding SLT use quit rates remained stable (41.3% vs. 40.0%, p = .87). Similar patterns were found in females with smoking quit rates increasing considerably (12.3% vs. 24.2%, p < .0001). Smoking quit rates increased in most sociodemographic groups analyzed. Male SLT use quit rates were significantly lower in SLT exclusive users than in dual users in the 2010-2011 cohort (40.0% vs. 62.2%; p = .04), but smoking quit rates in exclusive smokers and in dual users were roughly equivalent (24.4% vs. 29.5%, p = .68).ConclusionsAlthough smoking quit rates doubled overall and increased in most sociodemographic groups, SLT quit rates remained constant with little transition between products. Longer-term prospective data examining polytobacco use are needed to better understand transitions between tobacco products.ImplicationsThis study uses two longitudinal surveys to investigate changes in switching behaviors between tobacco products. We found that quit rates of self-reported smoking doubled between 2002-2003 and 2010-2011 in most sociodemographic groups in the United States, whereas in contrast quit rates of self-reported Smokeless Tobacco (SLT) use remained roughly constant. This explains in part the opposing trends of tobacco use by product in the United States, with smoking continuing its decrease, whereas SLT use remains constant. Moreover, smokers were unlikely to switch to other forms of tobacco compared to SLT users. Lastly, smoking cessation for dual users was not significantly different from that of exclusive smokers. Understanding transitions between smoking and SLT use is critical to assess the potential long-term impact of SLT use, and potentially that of other alternative tobacco products, on tobacco-related health outcomes.

Project description:BackgroundIndoor air pollution (IAP) and environmental tobacco smoke (ETS) are associated with lower respiratory tract illness (LRTI) or wheezing in children. However, the effect of the timing of these exposures, specifically antenatal versus postnatal, and of alternate fuel sources such as the increasingly used volatile organic compounds have not been well studied. We longitudinally investigated the effect of antenatal or postnatal IAP and ETS on LRTI or wheezing prevalence and severity in African infants.MethodsMother and infant pairs enrolled over a 3-year period in a birth cohort study in two centres in Paarl, South Africa, were followed for the first year of life for LRTI or wheezing illness. We measured exposure to IAP (particulate matter, nitrogen dioxide, sulphur dioxide, carbon monoxide, and volatile organic compounds benzene and toluene) using devices placed in homes, antenatally and postnatally. We measured ETS longitudinally by maternal self-report and by urine cotinine measures. Study staff trained in recognition of LRTI or wheeze documented all episodes, which were categorised according to WHO case definition criteria. We used multivariate logistic and Poisson regressions to explore associations.FindingsBetween March 1, 2012, and March 31, 2015, we enrolled 1137 mothers with 1143 livebirths. Of 1065 infants who attended at least one study visit, 524 episodes of LRTI occurred after discharge with a wheezing prevalence of 0·23 (95% CI 0·21-0·26) episodes per child year. Exposures associated with LRTI were antenatal maternal smoking (incidence rate ratio 1·62, 95% CI 1·14-2·30; p=0·004) or particulate matter (1·43, 1·06-1·95; p=0·008). Subanalyses of LRTI requiring hospitalisation (n=137) and supplemental oxygen (n=69) found antenatal toluene significantly increased the risk of LRTI-associated hospitalisation (odds ratio 5·13, 95% CI 1·43-18·36; p=0·012) and need for supplemental oxygen (13·21, 1·96-89·16; p=0·008). Wheezing illness was associated with both antenatal (incidence rate ratio 2·09, 95% CI 1·54-2·84; p<0·0001) and postnatal (1·27, 95% CI 1·03-1·56; p=0·024) maternal smoking. Antenatally, wheezing was associated with maternal passive smoke exposure (1·70, 1·25-2·31; p=0·001) and, postnatally, with any household member smoking (1·55, 1·17 -2·06; p=0·002).InterpretationAntenatal exposures were the predominant risk factors associated with LRTI or wheezing illness. Toluene was a novel exposure associated with severe LRTI. Urgent and effective interventions focusing on antenatal environmental factors are required, including smoking cessation programmes targeting women of childbearing age pre-conception and pregnant women.FundingBill & Melinda Gates Foundation, Discovery Foundation, South African Thoracic Society AstraZeneca Respiratory Fellowship, Medical Research Council South Africa, National Research Foundation South Africa, and CIDRI Clinical Fellowship.
