Poly-tobacco product use among a representative sample of Chinese current smokers: a population survey

Abstract BackgroundPoly-tobacco product use is increasingly popular, but little is known about the patterns, trends of concomitant use, and risk factors particularly in non-western countries.MethodA representative sample of 1139 current cigarette smokers aged 15+ (84.1% male) were telephone interviewed in Tobacco Control Policy-related Surveys in 2015-2017. Information collected included poly-tobacco use (PTU), smoking and socio-demographic characteristics. Associations of current PTU with related risk factors were analyzed using logistic regression with adjustment for confounders. Prevalence was weighted by age and sex of current cigarette users in the general population.Results 15.9% (95% CI 13.4-18.6%) were current poly-users, 12.3% (10.2-14.8%) used one tobacco product and 2.52% (1.59-3.97%) used two tobacco products in addition to cigarette. The co-use of cigarette with cigar was more common and the least co-use product was e-cigarette with cigarette. By age group, proportion of co-use of cigarette with waterpipe was highest in young poly-users, older age used more cigar and self-rolling cigarette in addition to cigarette. Prevalence of two products use with cigarette was low. Trends of concomitant use were varied. Current PTU was associated with being male (AOR 2.01, 95% CI 1.12-3.61), younger age (AORs range from 1.34-4.65, P for trend < .001) and less ready to quit (2.08, 1.09-3.97). ConclusionsPrevalence of PTU increased slowly by year, co-use of one tobacco product with cigarette was more common. Being male, younger and less ready to quit were associated with current PTU.

Objectives: In this study, we tested the use of ecigarette, cigarette, and dual use of both as predictors of heat-not-burn (HNB) tobacco product use onset among young adults, and examined common predictors of smoking cessation as predictors of HNB product use. Methods: We collected data from 2229 young adults [mean age = 21.1 (SD = 2.1); 55% women] in Hawaii, at 2 time-points 6 months apart. Results: Current cigarette-only use was the strongest concurrent predictor of HNB product use, followed by dual use, and ecigarette-only use. Among HNB product never users at Wave 1, dual and ecigarette-only use at Wave 1 significantly predicted HNB product use onset at Wave 2. Among cigarette smokers who had never used an HNB product at Wave 1, current use of ecigarette for help with smoking cessation predicted increased odds of HNB product use at 6-month follow-up. Conclusions: Although promoted as a safer alternative for exclusive cigarette smokers, HNB products may increase the risk of dual or poly-tobacco product use among young adults, including current exclusive e-cigarette users. Surveillance of HNB product use as a modified risk tobacco product may need to consider the effects of HNB products on poly-tobacco use among young people.

Abstract Introduction This study explores patterns of use of non-cigarette tobacco and nicotine products among adult cigarette smokers and recent ex-smokers. Along with cigarette smoking status we explore differences as a function of countries with different product regulations, gender and age. Methods Data came from the ITC Four Country Smoking and Vaping Wave 3 Survey conducted between February-June 2020. The analytic sample consisted of 9112 current cigarette smokers (at least monthly) and 1184 recent ex-smokers (quit cigarettes ≤ 2 years) from Australia, Canada, England, and the US. Respondents were asked about their cigarette smoking and current use of the following non-cigarette products: combustible tobacco (cigars, cigarillos, pipe, waterpipe); non-combustible tobacco (smokeless tobacco, and heated tobacco products (HTPs)); and non-tobacco nicotine products (nicotine vaping products (NVPs), nicotine replacement therapy (NRT), and nicotine pouches)). Results Overall, NVPs (13.7%) and NRT (10.9%) were the most reported nicotine products used, followed by cigars (5.3%), cigarillos (4.2%), and HTPs (3.5%). More than 21% current and recent ex-smokers of cigarettes reported using a non-tobacco nicotine product and non-combustible product, with respondents in England reporting the highest levels of use (>26%). Males, younger respondents, and current non-daily cigarette smokers were more likely to use non-cigarette nicotine products. Notably, 11.6% of ex-cigarette smokers were using other combustible tobacco. Conclusion Considerable percentages of current cigarette smokers and ex-smokers use non-cigarette nicotine products, and there are unexpectedly high levels of use of other combustible products by those recent ex-smokers of cigarettes which is concerning and has important implications for definitions of smoking cessation. Implications The tobacco product market has evolved to include new products which add to existing non-cigarette tobacco products creating a much more diverse nicotine market. This brief report provides a snapshot of use of various combustible and non-combustible nicotine containing products among current cigarette smokers and recent ex-smokers in four western countries. Our results indicate that use of non-cigarette tobacco and nicotine products among these cigarette smokers and recent ex-smokers is not low, particularly among males, younger and non-daily cigarette smokers. Use of other combustible tobacco among respondents that recently quit cigarette smoking is concerning and has important implications for definitions of smoking cessation. Increased emphasis on researching non-cigarette nicotine product use is warranted in tobacco control generally and smoking cessation in particular.

IntroductionModified risk tobacco product (MRTP) claims for heated tobacco products (HTPs) that convey reduced exposure compared with conventional cigarettes may promote product initiation and transition among young people. We assessed the effects of a hypothetical MRTP claim for HTPs on young adults’ intention and perceptions of using HTPs and whether these effects differed by their current cigarette and e-cigarette use.MethodsWe embedded a randomised between-subjects experiment into a web-based survey administered among a cohort of 2354 Southern California young adults (aged 20–23) in 2020. Participants viewed depictions of HTPs with an MRTP claim (n=1190) or no claim (n=1164). HTP use intention and HTP-related harm and use perceptions relative to cigarettes and e-cigarettes were assessed.ResultsOverall, participants who viewed versus did not view the claim did not differ in HTP use intention (28.5% vs 28.7%) but were more likely to perceive HTPs as less harmful than cigarettes (11.4% vs 7.0%; p<0.001). The experimental effect on HTP use intention did not differ among past 30-day cigarette smokers versus non-smokers (interaction adjusted OR (AOR)=0.78, 95% CI 0.36 to 1.76) but differed among past 30-day e-cigarette users versus non-users (interaction AOR=1.67, 95% CI 1.02 to 2.68).DiscussionThe hypothetical MRTP claim may lower young adults’ HTP harm perceptions compared with cigarettes but may not change HTP use intention overall or differentially for cigarette smokers. The larger effect on HTP use intention among e-cigarette users than non-users raises the question of whether MRTP claims may promote HTP use or HTP and e-cigarette dual use among young e-cigarette users.

Abstract Introduction Limited research exists about the possible cardiovascular effects of electronic nicotine delivery systems (ENDS). We therefore sought to compare exposure to known or potentially cardiotoxic volatile organic compounds (VOCs) in ENDS users, smokers, and dual users. Methods A total of 371 individuals from the Cardiovascular Injury due to Tobacco Use study, a cross-sectional study of healthy participants aged 21–45 years, were categorized as nonusers of tobacco (n = 87), sole ENDS users (n = 17), cigarette smokers (n = 237), and dual users (n = 30) based on 30-day self-reported tobacco product use patterns. Participants provided urine samples for VOC and nicotine metabolite measurement. We assessed associations between tobacco product use and VOC metabolite measures using multivariable-adjusted linear regression models. Results Mean (SD) age of the population was 32 (±6.8) years, 55% men. Mean urinary cotinine level in nonusers of tobacco was 2.6 ng/mg creatinine, whereas cotinine levels were similar across all tobacco product use categories (851.6–910.9 ng/mg creatinine). In multivariable-adjusted models, sole ENDS users had higher levels of metabolites of acrolein, acrylamide, acrylonitrile, and xylene compared with nonusers of tobacco, but lower levels of most VOC metabolites compared with cigarette smokers or dual users. In direct comparison of cigarettes smokers and dual users, we found lower levels of metabolites of styrene and xylene in dual users. Conclusion Although sole ENDS use may be associated with lower VOC exposure compared to cigarette smoking, further study is required to determine the potential health effects of the higher levels of certain reactive aldehydes, including acrolein, in ENDS users compared with nonusers of tobacco. Implications ENDS use in conjunction with other tobacco products may not significantly reduce exposure to VOC, but sole use does generally reduce some VOC exposure and warrants more in-depth studies.

Colorectal Adenoma Recurrence

1554 Background: Colorectal cancer incidence and mortality are increasing among individuals < 50 years of age. Data are limited regarding the epidemiology of colorectal adenomas in this younger age group. This study investigated and compared risk factors associated with recurrence of adenomas in individuals under and over 50 years of age. Methods: Pooled analyses from the Wheat Bran Fiber and Ursodeoxycholic Acid phase III, randomized, controlled clinical trials included 1,623 participants, aged 40-80 years. Each completed baseline questionnaires related to family history and lifestyle habits, had one or more colorectal adenomas removed at baseline, and had a follow-up colonoscopy during the trial (mean follow up 36 months). Univariate and multivariate logistic regression modeling estimated the association between age and colorectal adenoma recurrence, and evaluate multiple risk factors, while controlling for confounding factors. Results: A statistically significant increased trend was found for colorectal adenoma recurrence with increasing age ( Ptrend= < 0.001). Multivariate logistic regression revealed that risk factors significantly associated with adenoma recurrence in the ≥50 age group (n = 1,523) included history of previous polyps, characteristics of adenomas removed at baseline (multiple adenomas and villous feature), current smoking, and an increased waist circumference. Although risk profile in the < 50 age group (n = 95) shared similarities with that in the ≥50 age group (e.g., current smoking), there were a few notable differences: history of previous polyps was a more prominent predictor for recurrence for the < 50 (OR< 50 = 4.76 and OR≥50 = 1.33, Pinteraction = 0.042), whereas baseline characteristics of adenomas were more important for the ≥50 (multiple adenomas: OR< 50 = 0.40 and OR≥50 = 2.28, Pinteraction = 0.043). Conclusions: Predisposition to colorectal adenoma is a more important risk factor for recurrence in the < 50 as compared to the ≥50. Future studies need to identify susceptibility factors contributing to the increasing incidence of colorectal cancer in this younger age group.
