Project description:The present study sought to assess the prevalence and determinants of tobacco use (cigarette smoking and shisha use) and khat chewing among Yemeni adolescents, and to evaluate their knowledge and attitudes toward these habits. This school-based cross-sectional study was conducted among 13 to 19-year-old students attending middle/high schools (both private and public) across five main cities in Yemen. Data were collected using self-administered questionnaires comprising questions/items related to sociodemographic data, cigarette smoking, shisha use, khat chewing, and knowledge on and attitudes toward these habits. Bivariate and multivariate analyses were used to explore the most determinant factors. A total of 7505 students were recruited from 42 schools across five major cities in Yemen. The prevalence rates of khat chewing, cigarette smoking, and shisha use were 42.4%, 6.8%, and 19.3%, respectively. Compared to females, male subjects reported significantly higher prevalence of khat chewing (51.4% vs. 23.5%, p < 0.001), shisha use (20.3% vs. 17.2%, p < 0.01), and cigarette smoking (8.8% vs. 2.6%, p < 0.001). Male gender, older age, poor knowledge, khat chewing, parents' low education level, and parents' and peers' smoking habits were significant determinants of adolescents' cigarette smoking status. Private education, male gender, older age, poor knowledge, parents' low education level, and parents' and peers' khat chewing habits were significant determinants of adolescents' khat chewing status. The participant's knowledge of and attitudes toward tobacco use and khat chewing were inadequate. The prevalence of khat chewing, shisha use, and to lesser extent cigarette smoking among Yemeni adolescents is high that needs immediate intervention. The results highlight the urgent need to implement prevention strategies to tackle these habits among the youth in Yemen.

Project description:ObjectiveThe authors examined psychiatric comorbidities associated with alcohol use disorders and tobacco use disorders among heterosexual, bisexual, and gay and lesbian men and women in the United States and whether stress-related factors were predictive of comorbidities.MethodsThe authors used data from the National Epidemiologic Survey on Alcohol and Related Conditions-III (2012-2013, N=36,309) to examine the co-occurrence of past-year alcohol or tobacco use disorder with past-year anxiety disorders, mood disorders, and posttraumatic stress disorder by sexual identity (heterosexual, bisexual, gay or lesbian) and sex. The authors also examined the association of stress-related factors and social support with the presence of comorbidities.ResultsComorbidities were more prevalent among women and sexual minorities, particularly bisexual women. More than half of bisexual (55%) and gay or lesbian (51%) individuals who met criteria for a past-year alcohol use disorder had a psychiatric comorbidity, while only one-third of heterosexual individuals who met criteria for a past-year alcohol use disorder did. Similar differences were found among those who met criteria for a past-year tobacco use disorder. Among sexual minorities, the frequency of sexual orientation discrimination (adjusted odds ratio range=1.08-1.10), number of stressful life events (adjusted odds ratio range=1.25-1.43), and number of adverse childhood experiences (adjusted odds ratio range=1.04-1.18) were significantly associated with greater odds of comorbidities. Greater social support was significantly inversely associated with tobacco use disorder comorbidities (adjusted odds ratio range=0.96-0.97).ConclusionsThis research suggests that integrated substance use and mental health prevention and treatment programs are needed, particularly for individuals who identify as sexual minorities. The increased stressors experienced by sexual minority individuals may be important drivers of these high levels of comorbidities.

Project description:BackgroundLittle is known about the use of novel heated tobacco products (HTPs) in low- and middle-income countries. We examined among smokers in Mexico the prevalence and correlates of HTP use, as well as reasons for using HTPs.MethodsWe analyzed data from five surveys (November 2019-March 2021) of an open cohort of adult smokers (n = 6500), including an oversample of those who also use e-cigarettes. Mixed-effects multinomial logistic models were used to estimate associations between study variables and current HTP use or prior HTP trial relative to never trying HTPs.ResultsThe weighted prevalence of current HTP use was 1.1%. Independent correlates of current HTP use included smoking frequency, intention to quit, e-cigarette use, having partners/family-members who use e-cigarettes, friends who use HTPs, and exposure to HTP information inside/outside tobacco shops. Having partners/family members who smoke and not knowing about the harm of HTPs relative to cigarettes were associated with lower likelihood of current HTP use. Having tried HTPs was more likely among light daily smokers, those with family who use HTPs and exposure to HTP information outside shops and on newspapers/magazines. Among current users, the top reasons for using HTPs were greater social acceptability (50.6%) and lower perceived harm (34.9%) relative to cigarettes.ConclusionsUptake of HTPs appears relatively low among Mexican smokers, and correlates of use are similar to those for e-cigarette use. Further research is needed to determine if HTPs use promotes or impedes smoking cessation, given current HTP users are also likely to use various nicotine products.

Project description:BackgroundWhile the serotonin transporter (SLC6A4) gene, 5-HTTLPR, interacts with the social environment to influence both emotional self-regulation and smoking behavior, less is known about interactions between emotional self-regulation and 5-HTTLPR or their joint influence on tobacco use. Here, we examined such interactions among psychiatric inpatients, the population with the highest rates of smoking.MethodsParticipants (506 adults) were psychiatric inpatients at The Menninger Clinic in Houston TX between 2012 and 16. Most were white (89%), male (55%), with a mean age of 32.3 years. Participants completed the Difficulties in Emotional Regulation Scale (DERS) at admission. We examined interactions with smoking among three DERS subscales and 5-HTTLPR, controlling for sex, race and age.ResultsSmoking rates were higher among those with the 5-HTTPLR L'L' genotype compared to peers carrying an S' allele (47.9% vs. 37.4%, respectively). Among S' allele carrying participants, impulse control difficulties (OR = 1.09; 95%CI: 1.03-1.14) and lack of emotion clarity (OR = 1.06; 95%CI: 1.00-1.11) increased risk for ever using tobacco, while accessing more ways to regulate emotion (OR = 0.95; 95%CI: 0.92-0.99) offered a protective effect against ever using tobacco. Neither demographic nor DERS covariates were associated with using tobacco among the L'L' group.LimitationsThis ethnically homogenous sample limits generalizability and using a binary outcome can over-estimate a gene environment interaction effect.ConclusionsEmotional self-regulation exerts a stronger influence on using tobacco among carriers of an S' allele of 5-HTTLPR than peers with the L'L' genotype. Promoting emotional self-regulatory skills may have benefits for preventing tobacco use.

Project description:BACKGROUND:Cannabis use is more common among tobacco users than nonusers, and co-use (i.e., use of both substances individually) may be increasing. Better understanding of patterns and correlates of co-use is needed. The current study aimed to compare rates and correlates of tobacco and cannabis co-use by tobacco product among youth. METHODS:High school students who completed the 2013 Virginia Youth Survey and reported past 30-day tobacco use (cigarette, smokeless tobacco, cigar) were included (n = 1390). Prevalence of past 30-day tobacco-only and cannabis co-use was calculated. Demographic, tobacco, and other substance use characteristics were compared by co-use status. Multivariate logistic regression models examined correlates of co-use overall and by tobacco product. RESULTS:Over half of tobacco users were co-users. Poly-tobacco use, particularly combusted tobacco, was more prevalent among co-users. Past 30-day alcohol use and lifetime other illegal drug use/prescription drug misuse were common correlates of co-use. Black Non-Hispanic (NH) race/ethnicity was associated with co-use when restricted to cigarette users. "Other" race/ethnicity was associated with co-use in the overall model and when restricted to cigar users. Past 30-day cigarette smoking was associated with co-use in all models except among cigar smoking co-users. Conclusions/Importance: Rates and correlates of tobacco and cannabis co-use were not uniform and differed by tobacco product type. Tobacco and cannabis co-users may be at greater risk for negative health effects associated with inhaled tobacco and other risky substance use. The efficacy of prevention efforts may be improved if risk factors associated with product-specific co-use are considered.

Project description:IntroductionThe global tobacco epidemic contributes to more than 8 million deaths annually. However, most tobacco control interventions have been driven by an emphasis on smoked tobacco. Globally and more so in Nigeria, less attention has been paid to the similarly harmful smokeless tobacco (SLT) whose use appeals to a different demography. We examined the prevalence, patterns of use and correlates of SLT in Nigerian adults to guide targeted control efforts.MethodsWe conducted a secondary analysis of the 2012 Global Adult Tobacco Survey (GATS) data. We obtained data on 9,765 non-institutionalised adults aged 15 years and older. Variables included current SLT use, sociodemographic characteristics and perceived harm of SLT use. We used Chi-square test to examine associations and binary logistic regression to assess predictors of current SLT use. All analyses were conducted with sample-weighted data.ResultsThe prevalence of current SLT use was 1.9% of all adults. About 1.4% were daily users. The main types were snuff by nose (1.6%) and snuff by mouth (0.8%). There were higher odds of current SLT use for those in the South-East region (aOR = 13.99; 95% CI: 4.45-43.95), rural area residents (aOR = 1.56; 95% CI: 1.04-2.35), males (aOR = 4.43; 95% CI: 2.75-7.11), the 45-64 years age-group (aOR = 10.00; 95% CI: 4.12-24.29), those with no formal education (aOR = 2.67; 95% CI: 1.01-7.05), and those with no perception of harm from SLT use (aOR = 3.81, 95% CI: 2.61-5.56).ConclusionThe prevalence of SLT use among Nigerian adults was low with clearly identified predictors. While a majority were aware of harm from SLT use, an unacceptably high proportion remain unaware. We recommended targeted interventions to increase awareness of the harmful effects of SLT use especially among residents of the South-East, those in rural areas, males, and individuals with no formal education. We also recommended a follow-up survey.

Project description:IntroductionDespite the increased heated tobacco product (HTP) marketing in the United States, little is known about HTP perceptions and correlates of HTP use and use intentions among young adults.Aims and methodsUsing 2020 cross-sectional data from 2,470 young adults (ages 18-34) from 6 US metropolitan areas, we conducted exploratory factor analysis to identify factors regarding perceived utility/appeal of HTPs, specifically IQOS, and examined these factors in relation to lifetime HTP use and use intentions, using multivariable logistic and linear regression, respectively.Results19.1% had heard of HTPs and 4.1% ever used HTPs; 14.7% had heard of IQOS specifically and 2.8% were ever-users. Use intentions were low (M = 1.27, scale: 1 = not at all to 7 = extremely). Factor analysis identified five perceived utility/appeal factors: innovation (M = 3.17, scale: 1 = not at all to 7 = extremely), cigarette substitute (M = 2.99), and youth appeal (M = 2.82), e-cigarette/nicotine substitute (M = 2.36), and fashionable (M = 2.04). Controlling for sociodemographics and other tobacco use, perceiving IQOS as more fashionable and e-cigarette substitutes positively correlated with lifetime HTP use (aOR = 1.60, 95%CI = 1.17, 2.17; aOR = 1.48, 95%CI = 1.11, 1.97, respectively) and use intentions (β = 0.26, 95%CI = 0.21, 0.30; β = 0.14, 95%CI = 0.09, 0.18); perceiving IQOS as cigarette substitutes negatively correlated with ever use (aOR = 0.74, 95%CI = 0.56, 0.97) and use intentions (β = -0.06, 95%CI = -0.10, -0.03). Correlation patterns were similar among past-month cigarette, e-cigarette, and any-tobacco users.ConclusionsAlthough HTP awareness and use were low, monitoring HTP perceptions and reasons for use as HTPs become more prominent is critical in anticipating their potential impact, particularly as more products seek FDA authorization to use reduced risk or exposure marketing claims.ImplicationsAwareness, ever use, and intentions to use heated tobacco products (HTPs) were low among US young adults in 2020. Perceiving IQOS as fashionable and an e-cigarette substitute were positively correlated with ever use and intention to use HTPs. In addition, perceiving IQOS as a cigarette substitute was negatively correlated with ever use of HTPs and HTP use intentions. Continued surveillance on perceptions and use behaviors is needed to better understand use patterns, intentions to use, and reasons for using HTPs.

Project description:In areas where the practise of betel quid chewing is widespread and the chewers also often smoke and drink alcohol, the relation between oral precancerous lesion and condition to the three habits is probably complex. To explore such association and their attributable effect on oral leukoplakia (OL) and oral submucous fibrosis (OSF), a gender-age-matched case-control study was conducted at Kaohsiung, southern Taiwan. This study included 219 patients with newly diagnosed and histologically confirmed OL or OSF, and 876 randomly selected community controls. All information was collected by a structured questionnaire through in-person interviews. A preponderance of younger patients had OSF, while a predominance of older patients had OL. Betel quid chewing was strongly associated with both these oral diseases, the attributable fraction of OL being 73.2% and of OSF 85.4%. While the heterogeneity in risk for areca nut chewing across the two diseases was not apparent, betel quid chewing patients with OSF experienced a higher risk at each exposure level of chewing duration, quantity and cumulative measure than those who had OL. Alcohol intake did not appear to be a risk factor. However, cigarette smoking had a significant contribution to the risk of OL, and modified the effect of chewing based on an additive interaction model. For the two oral premalignant diseases combined, 86.5% was attributable to chewing and smoking. Our results suggested that, although betel quid chewing was a major cause for both OL and OSF, its effect might be difference between the two diseases. Cigarette smoking has a modifying effect in the development of oral leukoplakia.

Project description:In early adolescence, Hispanics self-report higher drug use rates compared to White and African American peers. Among adolescent users, heavy users have more negative behavioral and health consequences. The purpose of this cross-sectional study is to examine whether psychiatric symptoms, parental attachment, and reasons for use predict heavy alcohol and illicit drug use (more than 10 times in the past three months) among Hispanic adolescents.This study examines baseline data from a study evaluating a family based substance abuse treatment program for Hispanic adolescents. Participants were 14-17 years old (N = 156, 44% female). Adolescent reports on the Diagnostic Interview Schedule for Children Predictive Scales measured psychiatric symptoms of major depressive disorder, attention deficit hyperactivity disorder, conduct disorder, and anxiety. The Personal Experiences Inventory measured type and amount of drug use, as well as perceived social and psychological benefits of drug use. The Inventory of Parent and Peer Attachment measured trust, communication, and alienation between adolescents and their mothers. Logistic regression identified correlates of heavy alcohol use and heavy illicit drug use among Hispanic adolescents.Higher social benefits were associated with increased likelihood of heavy alcohol use. Conduct disorder, higher levels of maternal attachment, lower levels of acculturation, and higher levels of psychological benefits of use were associated with an increased likelihood of heavy illicit drug use.These findings support the assumption that substance use treatment among Hispanic adolescents must be capable of addressing co-occurring psychiatric disorders, familial relationships, and the individual reasons/motivators to use.

Project description:Despite a growing body of research examining correlates and consequences of COVID-19, few findings have been published among military veterans. This limitation is particularly concerning as preliminary data indicate that veterans may experience a higher rate of mortality compared to their civilian counterparts. One factor that may contribute to increased rates of death among veterans with COVID-19 is tobacco use. Indeed, findings from a recent meta-analysis highlight the association between lifetime smoking status and COVID-19 progression to more severe or critical conditions including death. Notably, prevalence rates of tobacco use are higher among veterans than civilians. Thus, the purpose of the current study was to examine demographic and medical variables that may contribute to likelihood of death among veterans testing positive for SARS-CoV-2. Additionally, we examined the unique influence of lifetime tobacco use on veteran mortality when added to the complete model. Retrospective chart reviews were conducted on 440 veterans (80.5% African American/Black) who tested positive for SARS-CoV-2 (7.3% deceased) at a large, southeastern Veterans Affairs (VA) hospital between March 11, 2020 and April 23, 2020, with data analysis occurring from May 26, 2020 to June 5, 2020. Older age, male gender, immunodeficiency, endocrine, and pulmonary diseases were positively related to the relative risk of death among SARS-CoV-2 positive veterans, with lifetime tobacco use predicting veteran mortality above and beyond these variables. Findings highlight the importance of assessing for lifetime tobacco use among SARS-CoV-2 positive patients and the relative importance of lifetime tobacco use as a risk factor for increased mortality.
