Prevalence of Tobacco Product Use
Cited 15 times
Analyses were conducted with the use of Stata 12 software.32 Prevalence estimates were weighted to represent the U.S. adult and youth populations. Variances were estimated with the method of balanced, repeated replications,33 with Fay’s adjustment set to 0.3 to increase the stability of estimates.34 The logit-transformation method was used to calculate confidence intervals. The tables show 95% confidence intervals for point estimates.
The prevalences of product awareness and use of each product type, use of any cigar, use of smokeless tobacco including snus pouches, and use of any tobacco were computed according to the use categories shown in Table S1 in the Supplementary Appendix as they pertained to adults and youths, stratified according to age group (12 to 14 years, 15 to 17 years, 18 to 24 years, or ≥25 years). Among adults, the prevalence of current regular use (cigarettes) or current use (other tobacco products) was also stratified according to sex, age, race or ethnic group, sexual orientation, educational attainment, total annual household income, and U.S. Census region. Among youths, the prevalences of ever use and use in the previous 30 days were also stratified according to sex, age, race or ethnic group, sexual orientation (asked of those ≥14 years of age), educational level, and U.S. Census region.
The prevalences of overall and product-specific single-product use and multiple-product use were determined in the entire adult study population, in the entire youth study population, among adult tobacco users, and among youth tobacco users. Among adult multiple-product users and separately among youth multiple-product users, all combinations of tobacco products used were determined, and each combination that accounted for at least 1% of multiple-product users is presented.

Smokeless Tobacco Use in College Students
Cited 11 times
The data presented in this paper are from a screener survey used to establish a cohort of college students for the Smokeless Tobacco Use in College Students Study. The goal of the overall study is to assess trajectories and correlates of SLT use in a cohort of college students by surveying them each semester beginning in their freshman year and continuing through the fall of their senior year. Colleges in NC and VA with freshman enrollment of 1000 or more were considered eligible for participation. Military schools, single-gender schools, and seminaries or “Bible” schools were excluded. Historically black colleges and universities were also excluded due to low prevalence of tobacco use among black college students (Sutfin et al., 2012 (link)). Of the 11 colleges and universities participating in the study, seven are located in North Carolina and four are in Virginia. Nine are public schools and two are private. Five schools are in rural communities, four are in suburban communities, and two are in urban communities. Undergraduate enrollment ranged from 4024 to 23,730 in 2009, the year prior to the screener survey.

Comprehensive Tobacco Use Assessment
Cited 10 times
For each type of tobacco product, participants were asked a series of questions, including whether they had heard of the product (except cigarettes, for which universal awareness was assumed); whether they had ever used the product, even one or two puffs or one or two times; whether they had used the product during the previous 30 days; on how many of the previous 30 days they had used the product; and how much of each type of product they had used in their lifetimes. Adult participants were also asked whether they had ever used the product “fairly regularly” and whether they now use the product every day, some days, or not at all (non-daily users of hookah were also asked their frequency of use). Adults who had ever used a product but now use it “not at all” were asked how long it had been since they quit using it (responses were given in days, months, or years).
Various categories of tobacco use were assessed for each type of tobacco product. Current use indicates that the participant now smokes or uses the product every day or some days (for each tobacco product other than hookah; for hookah, current use indicates that the participant now uses the product every day, some days, usually weekly, or usually monthly). Current regular use indicates that the participant has ever smoked or used the product “fairly regularly” and now smokes or uses the product every day or some days (for each tobacco product other than cigarettes and hookah; for cigarettes, current regular use indicates that the participant has smoked ≥100 cigarettes in his or her lifetime and now smokes every day or some days; for hookah, current regular use indicates that the participant has ever used the product “fairly regularly” and now uses the product every day, some days, usually weekly, or usually monthly). Table S1 in the Supplementary Appendix presents additional categories of tobacco use that were assessed for each type of tobacco product. In addition, for each use category, use of any cigar was defined as use of at least one type of cigar (traditional cigars, cigarillos, or filtered cigars), use of smokeless tobacco including snus pouches was defined as use of either product, and use of any tobacco was defined as use of at least one of the 10 (adults) or 12 (youths) types of tobacco products. An exception to the definition of “any tobacco use” was current use of tobacco among adults, which was determined on the basis of current regular use in the case of cigarettes and current use in the case of every other tobacco product. Defining nonuse of any cigars, smokeless tobacco including snus pouches, and any tobacco required complete data on all types of the respective tobacco products assessed.

Assessing E-Cigarette Perceptions and Use
A cross-sectional questionnaire regarding e-cigarettes and tobacco products was
created based on a review of the Centers for Disease Control (CDC) National
Youth Tobacco Survey (NYTS), current e-cigarette publications, tobacco
publications, and related news releases.15 (link)-19 (link, link, no link found, link) The NYTS was used as a
guide to quantify tobacco and e-cigarette use, while the publications by Weaver
et al and Gibson et al provided a framework for the questions about perception
of benefits and harms related to e-cigarettes. Survey questions about
e-cigarettes and smoking cessation were modeled after those found in the
publication by Franks et al.19 (link) Additional insight was
gathered by visiting local vape shops to help guide terminology and trends in
e-cigarette use. A draft questionnaire was presented at a roundtable discussion
to 20 faculty and administrators for feedback. To further improve validity, the
authors invited four college students to pilot the survey and review it for
readability. To assess reliability, 17 college students piloted the online
questionnaire two times each about one week apart. Responses of those students
were evaluated using Spearman’s correlation coefficients and Cronbach’s alpha. A
statistician reviewed the validity results and final revisions were made to the
questionnaire. The study was deemed exempt by the authors’ Institutional Review
Board (IRB).
The questionnaire was built with conditional logic to learn about personal use of
various tobacco forms based on definitions from the NYTS.18 Participants were divided into three groups current user, past user or never.
Consistent with the NYTS, use of traditional cigarettes was defined as smoking
at least 100 cigarettes or 5 packs ever. Use of combustible non-cigarette
tobacco (cigars, cigarillos, pipes, hookah, or little filtered cigars) was
defined as smoking at least 50 times ever. Use of smokeless tobacco (chewing
tobacco, snuff, snus, or dip) was defined as at least 20 uses ever. Use of
e-cigarettes was defined as using at least once ever. Never users are all
participants who selected “no” when asked if they had ever used the amount of
tobacco product as defined. To determine if participants were current or past
users, participants were asked if they now use each product every day, some days
or not at all. Those who selected every day or some days were considered current
users. If participants selected not at all then they were considered past users.
Perception of e-cigarettes compared to other tobacco products was assessed using
a 6-point Likert scale with 1 = strongly disagree, 2 = disagree, 3 = somewhat
disagree, 3.5 = unsure, 4 = somewhat agree, 5 = agree, 6 = strongly agree.
Additional questions asked about perceived risks and benefits of
e-cigarettes.

Cross-country survey on tobacco use
The survey focused on tobacco use and related factors, with a particular focus on IQOS. The survey was translated into Hebrew and Arabic by a professional translation company (Academic Language Experts), back-translated into English, and then examined by 2 bilingual reviewers to verify comparability across translations. Survey content was parallel across countries/languages, except for specific sociodemographics (i.e., origin, religiosity). Israel-based participants could choose to take the survey in Hebrew or Arabic. The survey took ~25 min to complete.
At the outset of the survey, participants were provided images of each tobacco product category and were instructed, “This survey asks about various types of products. We want to ensure that 3 product categories are clear: (1) Ordinary cigarettes are filled with tobacco, lit with a match or lighter, and burned to produce ashes. They can be factory-made or roll-your-own. (2) Vaping products (sometimes called e-cigarettes) heat a liquid only. Vaping products do not contain actual tobacco. The liquid often contains nicotine and is often flavored. (3) HTPs heat actual tobacco to create an emission that is inhaled. HTPs always contain actual tobacco in the form of sticks or capsules, or loose tobacco. Some HTPs may also have liquid, but also contain actual tobacco.”
HTP and other tobacco/nicotine product use. Participants were asked, “In your lifetime, have you ever used: (1) traditional, ordinary cigarettes—including roll-your-own cigarettes/tobacco? (2) e-cigarettes, vaping products or other electronic nicotine delivery devices (excluding IQOS or similar products)? and (3) HTPs, such as IQOS?” (yes vs. no). Among those reporting lifetime use, current use was assessed by asking, “In the past 30 days, how many days have you used [traditional cigarettes, e-cigarettes, HTPs]?” (no = 0; yes ≥ 1). We similarly assessed hookah/waterpipe/nargila, cigar, pipe, and smokeless tobacco use (reported separately and as use of any of the (4)). Variables were created to indicate current (past 30-day) and former (ever but not past 30-day) use of each product to characterize patterns in bivariate analyses; variables indicating current (vs. no current) use of cigarettes, e-cigarettes, and other tobacco products were used for multivariable analyses.
Interest in trying IQOS. Participants were asked: “How likely would you be to try IQOS?” (1 = not at all; 2 = a little; 3 = neutral/unsure; 4 = somewhat; 5 = very).
Sociodemographics. Sociodemographic factors included: age; gender; sexual orientation (heterosexual, other); race/ethnicity (in the US: White, Black, Asian, Hispanic; in Israel: Jewish, Arab); nativity; educational attainment (

Micronutrient Supplement and Tobacco Usage Survey
The women completed a questionnaire concerning age, body weight, health status, diet, and the use of micronutrient supplements, alcohol, and tobacco. Regular use of supplements was defined as use for more than three days per week, and the definition of a regular tobacco user was based on a plasma cotinine concentration > 85 nmol/L. This cut-off is commonly used to define both regular smokers [6 (link)] and the use of smokeless tobacco [7 (link)].

Bone Mineral Content Analysis Protocol
After removing the attachment on the right tibia, bone mineral content was measured. The tibia was dried at 105 °C for 48 h then defatted with ether for seven days and dried to constant weight at 105 °C. The dried bones were crushed and put in the crucible then carbonized on an electric furnace until smokeless and burned in a muffle furnace at 550–600 °C for 24 h (RC-MF12-30, Beijing Ruicheng Yongchuang Technology Co., Ltd., Beijing, China). After obtaining the tibia ash, it was made into sample decomposition liquid. The calcium (Ca) was analyzed by the Ethylene Diamine Tetraacetie Acid (EDTA) method according to the GB/T6436–2018. The phosphorus (P) was determined via the molybdate-yellow colorimetry method based on the GB/T6437–2018.

Tobacco Use Characteristics and Transition Patterns in Bangladesh

Sociodemographic characteristicsSociodemographic characteristics examined were sex, age group (15–17, 18–24, 25–39, 40–54, and ≥55 years), residence (urban, rural), marital status (married, single or living alone), and education level (illiterate, 1–8 years or ≥9 years), and the CASHPOR housing index as a proxy of socioeconomic status (SES) (low, intermediate, high). The CASHPOR index of housing conditions was originally constructed by the ITC researchers and used as the basis for stratification of the population by socioeconomic status21 .
Current tobacco useIn the current study, respondents were considered as current tobacco users if they reported current use of cigarettes, bidis or smokeless (SLT) products on a daily, weekly, or less than weekly basis (e.g. monthly), in the surveys. For users of smoking products, the question was: ‘Do you currently smoke cigarettes/bidis?’. Those who answered ‘yes’ (Wave 1) or ‘daily/weekly/less than weekly’ (Waves 2, 3, and 4) were categorized as current users. For the identification of SLT users, the relevant question asked in Waves 1 and 2 was: ‘In the past 6 months, have you used any smokeless products?’ (yes/no); and a response to the statement ‘I generally use SLT at least weekly.’ (yes/no). Those who responded ‘yes’ to both, were classified as current SLT users. In Waves 3 and 4, the question was asked: ‘Do you currently use SLT?’, with response options ‘daily’, ‘weekly’, or ‘less than weekly’ indicating current use. However, those who responded ‘no’ to all of the above, were classified as non-users or quitters.
Perceptions and reasons for quitting and transitionsA set of questions around perceptions and reasons why exclusive cigarette, bidis, and SLT users in Wave 1 transitioned to other tobacco products (either exclusively or as dual/poly users of other products) in subsequent waves, were assessed. Current tobacco users were asked a series of questions about why they started smoking cigarettes (Waves 2 to 4), bidis (Waves 2 to 4), or using SLT (Waves 3 to 4). Potential answers to the questions include the influence of friends/family; people on media (cigarettes and bidis); curiosity; to occupy time; the calming effects (cigarettes and bidis); sign of sophistication (cigarettes); the packaging (bidis and SLT); to reduce stress (SLT); to help quit tobacco (SLT); the taste (bidis and SLT); and considered to be less harmful (bidis and SLT). Respondents were asked to respond ‘yes’, ‘no’, and ‘don’t know’ to the series of questions in the relevant waves. Reasons for quitting in the following waves were assessed by a number of questions asking cigarette (Waves 2 to 3) and bidi (Waves 2 to 4) smokers, or SLT (Waves 3 to 4) users, whether any of the following reasons led them to think about quitting: concerns for health; concerns for others; fewer places to smoke; workplace restrictions (SLT); set an example for children; doctor’s advice; price; warning labels; friends/family disapprove; and society disapproves (SLT). The responses to these questions were ‘yes’, ‘no’, and ‘don’t know’.
It is worth noting that some questions were asked only in certain waves. Therefore, data were analyzed only among the waves for which data were available. Supplementary file Table 1 shows a list of all the full questions asked above in relation to perceptions and reasons for transitions/quitting in the ITC Bangladesh Survey.
