Support for and potential impacts of key Smokefree 2025 strategies among Maori who smoke.

AIM: The recently passed Smokefree Environments and Regulated Products (Smoked Tobacco) Amendment Act has the potential to profoundly reduce smoking prevalence and related health inequities experienced among Maori. This study examined support for, and potential impacts of, key measures included within the legislation. METHOD: Data came from Wave 1 (2017-2019) of the Te Ara Auahi Kore longitudinal study, which was conducted in partnership with five primary health organisations serving Maori communities. Participants were 701 Maori who smoked. Analysis included both descriptive analysis and logistic regression. RESULTS: More Maori participants supported than did not support the Smokefree 2025 (SF2025) goal of reducing smoking prevalence to below 5%, and the key associated measures. Support was greatest for mandating very low nicotine cigarettes (VLNCs). Participants also believed VLNCs would prompt high rates of quitting. Participants who had made more quit attempts or reported less control over their life were more likely to support VLNCs. CONCLUSION: There was support for the SF2025 goal and for key measures that could achieve it. In particular, VLNCs may have significant potential to reduce smoking prevalence among Maori. As part of developing and implementing these measures it will be important to engage with Maori who smoke and their communities.

Associations of polygenic risk scores for smoking heaviness and lifetime cannabis use with tobacco and cannabis co-use trajectories among African Americans.

BACKGROUND: We aimed to identify distinct trajectories of tobacco, cannabis, and their co-use among African Americans, and to investigate whether these patterns were associated with polygenic risk scores (PRS) for tobacco and cannabis use. METHOD: Participants (N=428 participants; 50.9% male) were initially recruited for an elementary school-based prevention in a Mid-Atlantic city when they were in first grade. From ages 14-26, participants reported on their frequency of tobacco and cannabis use in the past year during annual assessments. DNA was collected from participants at age 21. PRS for smoking heaviness (i.e., cigarettes per day) and lifetime cannabis use were created based on genome-wide association study results derived from Liu et al. (2019) and Pasman et al. (2018), respectively. RESULTS: We identified five distinct trajectories of tobacco and cannabis co-use, including (1) Low Tobacco and Cannabis Use, (2) Adolescent Limited Tobacco and Cannabis Use, (3) Experimental Cannabis, Young Adult Increasing Tobacco, (4) Experimental Tobacco, Young Adult Increasing Cannabis, and (5) High, Chronic Tobacco and Cannabis Use. Compared to the Low Tobacco and Cannabis Use subgroup, individuals in the High, Chronic Tobacco and Cannabis Use subgroup had greater PRS for smoking heaviness, and individuals in the Experimental Cannabis, Young Adult Increasing Tobacco subgroup had higher PRS for lifetime cannabis use. CONCLUSIONS: Polygenic risk for lifetime cannabis use and smoking heaviness is associated with the developmental progression of tobacco and cannabis co-use among African Americans, furthering knowledge on the etiology of co-use in this population.

Acculturation level and change in cigarette consumption behaviors among diverse Hispanics/Latinos: the Hispanic Community Health Study/Study of Latinos.

PURPOSE: To study associations between language acculturation level and changes in cigarette consumption among the diverse and growing U.S.-based Hispanic/Latino population and inform culturally tailored smoking prevention and cessation strategies. METHODS: In the Hispanic Community Health Survey/Study of Latinos cohort, we used cigarette consumption behaviors at baseline (2008-2011) and follow-up (2014-2017) and a modified Short Acculturation Scale for Hispanics (SASH) language subscale to measure associations of language acculturation (unidimensional) with changes in cigarette consumption and quitting rates. Weighted multivariable linear and logistic regressions were stratified by daily (n = 1397) and nondaily (n = 633) smoking, and either sex, educational attainment, or migration status. RESULTS: Smokers at baseline (n = 2030) on average were aged 42 years old (SE = 0.5) with a mean SASH-language score of 2.3 (SE = 0.1; range = 1-5), indicating more Spanish language use. Among male daily smokers, we observed increases in smoked cigarettes-per-day (CPD) with unit increases in SASH-language score (1.08, 95% CI: 0.24-1.92). Associations with acculturation trended toward greater increases in CPD and lower odds of quitting as educational attainment increased. CONCLUSIONS: Language acculturation level is an important determinant for increased smoking behaviors, particularly among men. Our findings are significant in informing smoking reduction programs for the Hispanic/Latino population.

Associations between anxiety symptoms and barriers to smoking cessation among African Americans who smoke cigarettes daily.

BACKGROUND: African Americans who smoke cigarettes and experience heightened anxiety symptoms may have low quit smoking rates. Identifying which particular barriers to cessation are associated with specific types of anxiety symptoms in African Americans could inform cessation treatments for this population. This cross-sectional, correlational study examined associations of anxiety-related symptoms and distinct barriers to cessation among non-treatment-seeking African Americans who smoke cigarettes daily. METHODS: African Americans who smoke (N = 536) enrolled in a clinical research study on individual differences in tobacco addiction between 2013 and 2017 completed self-report measures of anxiety-related symptoms (i.e., social anxiety, panic, and posttraumatic intrusions) and types of barriers to cessation (i.e., addiction-related, social-related, and affect-related barriers). Linear regression models tested associations of anxiety symptoms with cessation barriers with and without adjusting for age, sex, depressive symptoms, and nicotine dependence. RESULTS: All anxiety-related symptoms were associated with each cessation barrier (ßs = 0.240-0.396). After covariate adjustment, panic and trauma-related symptoms were not associated with cessation barriers, and the strength of association of social anxiety with external barriers was reduced but remained significant (ß = 0.254). CONCLUSION: Symptoms of social anxiety, but not trauma or panic-related symptoms, may play a unique, but modest, role in certain barriers to cessation in non-treatment-seeking African Americans who smoke cigarettes over. Further research is needed to uncover why African Americans who smoke and have anxiety might experience these barriers, and how future interventions can mitigate these obstacles.

Smoking Behaviors Among Indigenous Pregnant People Compared to a Matched Regional Cohort.

INTRODUCTION: Smoking commercial tobacco products is highly prevalent in American Indian and Alaska Native (Indigenous) pregnancies. This disparity directly contributes to maternal and fetal mortality. Our objective was to describe cigarette smoking prevalence, cessation intervention uptake, and cessation behaviors of pregnant Indigenous people compared to sex and age-matched regional cohort. AIMS AND METHODS: Pregnancies from an Indigenous cohort in Olmsted County, Minnesota, identified in the Rochester Epidemiology Project, were compared to pregnancies identified in a sex and age-matched non-Indigenous cohort from 2006 to 2019. Smoking status was defined as current, former, or never. All pregnancies were reviewed to identify cessation interventions and cessation events. The primary outcome was smoking prevalence during pregnancy, with secondary outcomes measuring uptake of smoking cessation interventions and cessation. RESULTS: The Indigenous cohort included 57 people with 81 pregnancies, compared to 226 non-Indigenous people with 358 pregnancies. Smoking was identified during 45.7% of Indigenous pregnancies versus 11.2% of non-Indigenous pregnancies (RR: 3.25, 95% CI = 1.98-5.31, p ≤ .0001). Although there was no difference in uptake of cessation interventions between cohorts, smoking cessation was significantly less likely during Indigenous pregnancies compared to non-Indigenous pregnancies (OR: 0.23, 95% CI = 0.07-0.72, p = .012). CONCLUSIONS: Indigenous pregnant people in Olmsted County, Minnesota were more than three times as likely to smoke cigarettes during pregnancy compared to the non-indigenous cohort. Despite equivalent uptake of cessation interventions, Indigenous people were less likely to quit than non-Indigenous people. Understanding why conventional smoking cessation interventions were ineffective at promoting cessation during pregnancy among Indigenous women warrants further study. IMPLICATIONS: Indigenous pregnant people in Olmsted County, Minnesota, were greater than three times more likely to smoke during pregnancy compared to a regional age matched non-Indigenous cohort. Although Indigenous and non-Indigenous pregnant people had equivalent uptake of cessation interventions offered during pregnancy, Indigenous people were significantly less likely to quit smoking before fetal delivery. This disparity in the effectiveness of standard of care interventions highlights the need for further study to understand barriers to cessation in pregnant Indigenous people.

Race, Concern About COVID-19 Discrimination, and Cigarette Smoking Behavior: Comparison Between US Asian and White Adults Who Use Commercial Tobacco.

Anti-Asian discrimination incidents in the USA have resurged during the COVID-19 pandemic. It is unclear how concern about being discriminatorily treated due to the COVID-19 pandemic varies between Asian and Asian American (A&AsA) and White adults. We examined A&AsA vs. White differences in concern about COVID-19 discrimination and associations of this concern with changes in cigarette smoking behaviors before and during the pandemic. Data were from a US representative sample of A&AsA and White adults (≥ 21 years) who currently and formerly used commercial tobacco (n = 1052), collected through an online panel oversampling A&AsA adults in January-February 2021. Participants reported their concern, worry, and stress about COVID-19 discrimination and past-30-day cigarette consumption before and during the pandemic. We examined the association between race and overall concern about COVID-19 discrimination, and this concern's associations with changes in past-30-day cigarette smoking consumption, smoking continuation, and return to smoking using weighted multivariable logistic and linear regression models. Overall concern about COVID-19 discrimination was higher (adjusted mean = 1.7, standard error = 0.16) among A&AsA adults who currently and formerly used commercial tobacco than their White counterparts (adjusted mean = 0.60, standard error = 0.04; p < 0.01). Overall concern about COVID-19 discrimination was associated with increased past-30-day cigarette consumption by 26.5 cigarettes (95% confidence interval [CI] = 1.2-51.9) and 4.4 times (95% CI = 2.3-8.5) greater odds of return to smoking among adults who smoke cigarettes. A&AsA adults who currently and formerly used commercial tobacco disproportionately bore higher concern about COVID-19 discrimination, and in turn could lead to increased smoking behavior and related morbidity and mortality among A&AsA adults.

Racial disparities in intensity of smoke exposure and nicotine intake among low-dependence smokers.

BACKGROUND: Compared to white smokers, Black smokers are at disproportionately higher risk for smoking-related disease, despite consuming fewer cigarettes per day (CPD). To examine racial disparities in biobehavioral influences on smoking and disease risk, we analyzed the relationship between self-reported tobacco dependence and intensity of tobacco smoke exposure per cigarette, on the one hand, and intensity of nicotine intake per cigarette, on the other. METHODS: In 270 Black and 516 white smokers, smoke exposure was measured by expired carbon monoxide (CO), and nicotine intake was measured by plasma cotinine (COT) and cotinine+3'-hydroxycotinine ([COT + 3HC]). Using linear regression analyses, we analyzed how the Fagerström Test for Cigarette Dependence (FTCD) predicted intensity of smoke exposure per cigarette (CO/CPD) and intensity of nicotine intake per cigarette (COT/CPD; [COT + 3HC]/CPD), and how race moderated these relations. RESULTS: Overall, Black smokers consumed fewer CPD than white smokers and had higher levels of CO/CPD, COT/CPD, and [COT + 3HC]/CPD. These elevations were most pronounced at lower levels of dependence: amongst Black smokers, FTCD negatively predicted intensity of smoke exposure as measured by CO/CPD (B = -0.12, 95% CI = -0.18, -0.05, p = 0.0003) and intensity of nicotine intake as measured by [COT + 3HC]/CPD (B = -1.31, 95% CI = -2.15, -0.46, p = 0.002). CONCLUSIONS: Low-dependence Black smokers had higher intensities of both smoke exposure and nicotine intake per cigarette compared to similarly dependent white smokers, suggesting that measures of dependence, exposure, and intake underestimate incremental risk of each cigarette to Black smokers.

Age at Initiation of Cigarette Use in a Nationally Representative Sample of US Youth, 2013-2017.

Importance: Cigarettes are still a commonly used tobacco product among youth despite recent declines in cigarette use. Objective: The aim of this study was to prospectively estimate the age of cigarette use initiation among youth (aged 12-17 years) overall, by sex, and by race/ethnicity. Design, Setting, and Participants: This cohort study used data from waves 1 through 4 of the nationally representative Population Assessment of Tobacco and Health (PATH) study, conducted from September 12, 2013, to January 3, 2018. Two subpopulations of youth were assessed: (1) those nonsusceptible to cigarette use and (2) never users of cigarettes at their first wave of PATH participation. Weighted interval-censoring survival analyses were used to prospectively estimate the age of initiation of cigarette use outcomes. Weighted interval-censoring Cox proportional hazard models were used to estimate differences in the age of initiation by sex and by race/ethnicity. Statistical analyses were performed from October 7, 2019, to May 1, 2020. Exposures: Differences in the age of initiation by sex and race/ethnicity. Main Outcomes and Measures: Age of initiation of susceptibility to cigarette use, ever use, past 30-day use, and fairly regular cigarette use overall, by sex, and by race/ethnicity. Results: A total of 15 776 youth never users and, among them, 11 022 youth who were nonsusceptible to cigarette use, were included in this study (weighted mean [SE] age, 13.5 [0.01] years; 58.6% [SE, 0.46%] non-Hispanic White; and 51.0% [SE, 0.32%] boys) and 15 776 were never users of cigarettes at their first wave of PATH participation (weighted mean [SE] age, 13.7 [0.01] years; 55.0% [SE, 0.29%] non-Hispanic White; and 51.0% [SE, 0.15%] boys). By age 18 years, among those who were nonsusceptible, 46.2% (95% CI, 44.3%-48.2%) became susceptible to cigarette use. Among never users, 24.4% (95% CI, 22.9%-25.9%) initiated ever cigarette use, 16.4% (95% CI, 15.2%-17.6%) initiated past 30-day cigarette use, and 4.3% (95% CI, 3.9%-4.8%) initiated fairly regular cigarette use. Boys had a higher risk of initiating ever (hazard ratio [HR], 1.21; 95% CI, 1.08-1.36) and past 30-day cigarette use (HR, 1.27; 95% CI, 1.10-1.47) at earlier ages compared with girls. Non-Hispanic White youth had a higher risk of an earlier age of initiation of susceptibility to cigarette use (HR, 0.77; 95% CI, 0.68-0.88), ever use (HR, 0.59; 95% CI, 0.49-0.71), past 30-day use (HR, 0.64; 95% CI, 0.52-0.77), and fairly regular cigarette use (HR, 0.25; 95% CI, 0.14-0.43) compared with non-Hispanic Black youth. Conclusions and Relevance: The results of this cohort study suggest that, despite current interventions and existing laws, a large number of youth initiated cigarette use before the legal age to purchase tobacco products.

Social determinants of alcohol and cigarette use by race/ethnicity: Can we ignore measurement issues?

Psychometric critiques of cross-cultural research emphasize testing whether instruments measure the same construct across cultural groups. We tested for measurement invariance (by race/ethnicity) of instruments used to evaluate the relationship between alcohol and tobacco use with perceived discrimination and socioeconomic status (SES). Tests of psychometric equivalence across race/ethnicity focused on: the latent organization of constructs (configural invariance); if observed indicators have equal factor loadings or "true score" variance (metric invariance); and whether manifest indicators change uniformly contingent on change in the latent variable (scalar invariance). A cross-sectional survey of 2,376 cigarette smokers (794 Black, 786 Latinx, 796 White; mean age = 43 [SD = 12]; 58% female) was recruited via an online research panel. Discrimination was indicated by self-report; SES was indicated by self-reported education, employment, income, and the "SES Ladder;" alcohol use was indicated by frequency and typical quantity of drinking, and frequency of heavy drinking; tobacco use was indicated by frequency of smoking, cigarettes per smoking day, and time to first cigarette. All instruments demonstrated configural invariance; either full metric invariance (alcohol and discrimination) or partial metric invariance (tobacco and SES); and all constructs demonstrated partial scalar invariance. Results support psychometric critiques; for example, all of the SES indicators violated assumptions of classical measurement theory for valid between group comparisons. All of our instruments displayed some degree of systematic bias in measurement across race/ethnicity. Studies testing ethnic/racial differences may need to move beyond classical measurement theory, and may benefit from using statistical approaches that can test for (and model) bias in measurement.

Sociodemographic Determinants of Life's Simple 7: Implications for Achieving Cardiovascular Health and Health Equity Goals.

Background: Life's Simple 7 (LS7; nutrition, physical activity, cigarette use, body mass index, blood pressure, cholesterol, glucose) predicts cardiovascular health. The principal objective of our study was to define demographic and socioeconomic factors associated with LS7 to better inform programs addressing cardiovascular health and health equity. Methods: National Health and Nutrition Examination Surveys 1999-2016 data were analyzed on non-Hispanic White [NHW], NH Black [NHB], and Hispanic adults aged ≥20 years without cardiovascular disease. Each LS7 variable was assigned 0, 1, or 2 points for poor, intermediate, and ideal levels, respectively. Composite LS7 scores were grouped as poor (0-4 points), intermediate (5-9), and ideal (10-14). Results: 32,803 adults were included. Mean composite LS7 scores were below ideal across race/ethnicity groups. After adjusting for confounders, NHBs were less likely to have optimal LS7 scores than NHW (multivariable odds ratios (OR .44; 95% CI .37-.53), whereas Hispanics tended to have better scores (1.18; .96-1.44). Hispanics had more ideal LS7 scores than NHBs, although Hispanics had lower incomes and less education, which were independently associated with fewer ideal LS7 scores. Adults aged ≥45 years were less likely to have ideal LS7 scores (.11; .09-.12) than adults aged <45 years. Conclusions: NHBs were the least likely to have optimal scores, despite higher incomes and more education than Hispanics, consistent with structural racism and Hispanic paradox. Programs to optimize lifestyle should begin in childhood to mitigate precipitous age-related declines in LS7 scores, especially in at-risk groups. Promoting higher education and reducing poverty are also important.

Prenatal cigarette smoking as a mediator between racism and depressive symptoms: The Biosocial Impact on Black Births Study.

OBJECTIVE: This study examined whether cigarette smoking mediated the association of racial discrimination with depressive symptoms among pregnant Black women. DESIGN: Cross-sectional. SAMPLE: Two hundred Black women at 8-29 weeks gestation. MEASUREMENTS: Women completed questionnaires including the Experiences of Discrimination and the Center for Epidemiologic Studies-Depression (CES-D) scales, as well as questions about sociodemographic characteristics and cigarette smoking. RESULTS: The mean age of the sample was 26.9 ± 5.7 years and the mean gestational age at data collection was 15.6 ± 5.7 weeks. Approximately 17% of women reported prenatal cigarette smoking; 27% had prenatal CES-D scores ≥23, which have been correlated with depression diagnoses; and 59% reported ever (lifetime) experiencing discrimination in at least one situation (e.g., at work). Path analysis results indicated that the standardized indirect effect of experiences of racial discrimination on CES-D scores through prenatal smoking was statistically significant (standardized indirect effect = 0.03; 95% CI: 0.001, 0.094; p = .042). CONCLUSION: Cigarette smoking during pregnancy partially mediated the association between lifetime experiences of racial discrimination and prenatal depressive symptoms among pregnant Black women. Smoking cessation programs should focus on identifying and treating depressive symptoms among pregnant Black women.

The prevalence and factors associated with alcohol use disorder among people living with HIV/AIDS in Africa: a systematic review and meta-analysis.

BACKGROUND: Alcohol use disorder (AUD) in HIV/AIDS patient's decreases adherence and effectiveness of medications and help-seeking to HIV/AIDS care and treatment. This study, therefore, assessed the average 1 year prevalence and associated factors of alcohol use disorder in HIV/AIDS patients. METHODS: We did an electronic data search on PubMed, Scopus, EMBASE, Psych-INFO libraries, African index Medicus and African Journals Online (AJOL). Google scholar was also investigated for non-published articles. The reference lists of published articles were also reviewed. The stata-11meta-prop package was employed. Subgroup and sensitivity analyses were done. Cochran's Q-statistics and the Higgs I2 test were used to check heterogeneity. Publication bias was evaluated with Egger's test and funnel plots. RESULTS: Of 1362 articles identified using the search strategies; only 22 studies were included in the final analysis. The average 1 year prevalence of AUD was 22.03% (95% CI: 17.18, 28.67). The average prevalence of AUD in South Africa (28.77%) was higher than in Uganda (16.61%) and Nigeria (22.8%). The prevalence of AUD in studies published before 2011, 2011-2015, and after 2015 was found to be 13.47, 24.93, and 22.88% respectively. The average prevalence of AUD among studies with a sample size > 450 was 16.71% whereas it was 26.46% among studies with a sample size < 450. Furthermore, the average prevalence of hazardous, harmful, and dependent drinking was 10.87, 8.1, and 3.12% respectively. Our narrative analysis showed that male sex, cigarette smoking, family history of alcohol use, missing ART medication, mental distress, khat chewing, low CD4 count, and low income were among the associated factors for AUD in people with HIV AIDS. On quantitative meta-analysis for associated factors of AUD, the AOR of being male, Cigarette smoking and khat chewing were 5.5, 3.95, and 3.34 respectively. CONCLUSION: The average 1 year prevalence of AUD in HIV/AIDs patients was high and qualitatively factors such as being Male, cigarette smoking, and khat chewing were associated with it. Therefore, clinical services for people living with HIV/AIDS should integrate this public health problem. Policymakers should also develop guidelines and implementation strategies for addressing this problem.

How Is Use of Electronic Cigarettes Related to Conventional Cigarette Use? A Qualitative Study among Korean American Young Adults.

Given the growing popularity of e-cigarettes in the United States, there is a need to understand the relationship between conventional and electronic cigarette use among Korean American young adults. Thus, this study aimed to explore Korean American young adults' experience of electronic cigarettes and its association with use of conventional cigarettes. This study employed an exploratory qualitative design. Individual interviews were conducted with 15 Korean American young adults aged between 18 and 25 years who reported having smoked at least one conventional cigarette per day for the past 6 months. Interview data were subjected to thematic analysis in order to gain an in-depth understanding of the interconnection between e-cigarette and conventional cigarette use. Data analysis revealed three themes involving reasons for buying, using, and stopping use of e-cigarettes, each of which had several sub-themes. Study results suggest that experience of e-cigarettes was related to conventional cigarette use. Thus, the experience of e-cigarettes as well as conventional cigarettes should be considered in designing smoking cessation interventions for Korean American young adults.

Cigarette Smoking and Incident Stroke in Blacks of the Jackson Heart Study.

Background Blacks are disproportionately affected by stroke compared with whites; however, less is known about the relationship between stroke and cigarette smoking in blacks. Therefore, we evaluated the relationship between cigarette smoking and all incident stroke in the JHS (Jackson Heart Study). Methods and Results JHS participants without a history of stroke (n=4410) were classified by self-reported baseline smoking status into current, past (smoked at least 400 cigarettes/life), or never smokers at baseline (2000-2004). Current smokers were further classified by smoking intensity (number of cigarettes smoked per day [1-19 and ≥20]) and followed up for incident stroke (through 2015). Hazard ratios (HRs) for incident stroke for current and past smoking compared with never smoking were estimated with adjusted Cox proportional hazard regression models. After adjusting for cardiovascular risk factors, the risk for stroke in current smokers was significantly higher compared with never smokers (HR, 2.48; 95% CI, 1.60-3.83) but there was no significant difference between past smokers and never smokers (HR, 1.10; 95% CI, 0.74-1.64). There was a dose-dependent increased risk of stroke with smoking intensity (HR, 2.28 [95% CI, 1.38-3.86] and HR, 2.78 [95% CI, 1.47-5.28] for current smokers smoking 1-19 and ≥20 cigarettes/day, respectively). Conclusions In a large cohort of blacks, current cigarette smoking was associated with a dose-dependent higher risk of all stroke. In addition, past smokers did not have a significantly increased risk of all stroke compared with never smokers, which suggests that smoking cessation may have potential benefits in reducing the incidence of stroke in blacks.

Cessation Conversations and Quit Attempts: Differences by Ethnicity and Language Preference.

Objectives: Conversations about pictorial cigarette health warning labels (HWLs) encourage quit attempts, and prior research suggests prevalence of these conversations varies by ethnicity. We assessed the frequency of conversations about text-only HWLs among Latino and non-Latino white smokers and the relationship between conversations and subsequent quit attempts. Methods: Latino and non-Latino white adult smokers in the United States (N = 4403) were surveyed every 4 months over 2 years. Surveys queried smoking behaviors, recent quit attempts, HWL responses, including HWL conversations, and socio-demographic variables. Negative binomial generalized estimating equation (GEE) models regressed the frequency of HWL conversations on study variables. Logistic GEE models regressed quit attempts at follow-up surveys on responses from the prior wave, including frequency of HWL conversations and their interaction with ethnicity. Results: Spanish preference Latinos reported the most HWL conversations (85%), followed by English preference Latinos (59%), and non-Latino Whites (35%). More frequent HWL conversations predicted subsequent quit attempts (AOR = 1.74, 95% CI = 1.32, 2.30), but ethnicity did not moderate this effect. Conclusions: Latinos appear to talk more frequently about HWLs than non-Latino Whites but are no more likely to quit as a result. Cessation campaigns should use messages that encourage conversations about quitting.

Cigarette smoking and smokeless tobacco use among male south Asian migrants in the United Arab Emirates: a cross-sectional study.

BACKGROUND: Few data were available on smoking and smokeless tobacco use in South Asian migrants in the United Arab Emirates (UAE). This study aimed to identify the prevalence and correlates of cigarette smoking and smokeless tobacco use in male South Asian migrants in the UAE. METHODS: We used a cross-sectional study to recruit a random representative sample of male South Asian migrants, including Indian (n = 433), Pakistani (n = 383) and Bangladeshi (n = 559) nationalities. We used multivariable logistic regression analysis to identify significant correlates of cigarettes smoking and smokeless tobacco use. RESULTS: 1375 South Asian migrant adult males participated in the study (response rate 76%) with a mean age of 34 years (SD ± 10). The overall prevalence of cigarette smoking was 28% (95%CI 25-30%) and smokeless tobacco use was 11% (95%CI 10-13%). The prevalence of current cigarette smoking was 21, 23, and 37% among participants from India, Pakistan and Bangladesh, respectively. The prevalence of current smokeless tobacco use was 6, 12, and 16% for Indian, Pakistani, and Bangladeshi participants, respectively. Among study participants, Bangladeshi nationality, hypertension, and alcohol use were significant correlates of current cigarette smoking. Significant correlates of smokeless tobacco use included increased age, less than college level education, alcohol use, and Pakistani or Bangladeshi nationality. CONCLUSIONS: Current smoking and smokeless tobacco use in South Asian migrants represent a significant public health burden in the UAE. Effective public health measures are needed to reduce tobacco use in this migrant population.

Smoking-by-genotype interaction in type 2 diabetes risk and fasting glucose.

Smoking is a potentially causal behavioral risk factor for type 2 diabetes (T2D), but not all smokers develop T2D. It is unknown whether genetic factors partially explain this variation. We performed genome-environment-wide interaction studies to identify loci exhibiting potential interaction with baseline smoking status (ever vs. never) on incident T2D and fasting glucose (FG). Analyses were performed in participants of European (EA) and African ancestry (AA) separately. Discovery analyses were conducted using genotype data from the 50,000-single-nucleotide polymorphism (SNP) ITMAT-Broad-CARe (IBC) array in 5 cohorts from from the Candidate Gene Association Resource Consortium (n = 23,189). Replication was performed in up to 16 studies from the Cohorts for Heart Aging Research in Genomic Epidemiology Consortium (n = 74,584). In meta-analysis of discovery and replication estimates, 5 SNPs met at least one criterion for potential interaction with smoking on incident T2D at p<1x10-7 (adjusted for multiple hypothesis-testing with the IBC array). Two SNPs had significant joint effects in the overall model and significant main effects only in one smoking stratum: rs140637 (FBN1) in AA individuals had a significant main effect only among smokers, and rs1444261 (closest gene C2orf63) in EA individuals had a significant main effect only among nonsmokers. Three additional SNPs were identified as having potential interaction by exhibiting a significant main effects only in smokers: rs1801232 (CUBN) in AA individuals, rs12243326 (TCF7L2) in EA individuals, and rs4132670 (TCF7L2) in EA individuals. No SNP met significance for potential interaction with smoking on baseline FG. The identification of these loci provides evidence for genetic interactions with smoking exposure that may explain some of the heterogeneity in the association between smoking and T2D.

Youth Perceptions of Parental Involvement and Monitoring, Discrepancies With Parental Perceptions, and Their Associations With First Cigarette Use in Black and White Girls.

OBJECTIVE: Low parental involvement and monitoring are risk factors for adolescent cigarette use. Assessments of parental involvement and monitoring by youth and parents may capture an additional source of risk: differences in perceptions of these parenting behaviors. This study tested for unique contributions of youth-reported parental involvement and monitoring and youth-parent discrepancies in reporting to first cigarette use in girls. METHOD: Data were drawn from interviews at ages 8-17 with 1,869 girls (57.3% Black, 42.7% White) and their primary caregivers (94% mothers) in the Pittsburgh Girls Study. Cox proportional hazards regression analyses were conducted to predict first cigarette use as a function of girls' reports of parental involvement and monitoring, magnitude and direction of youth-parent reporting discrepancies, and the interaction between them, adjusting for neighborhood, socioeconomic, and individual level factors. RESULTS: High magnitude of discrepancy in parental involvement reports (hazard ratio [HR] = 1.14, 95% confidence interval [CI] [1.03, 1.26]) and lower perceived parental involvement by girls (HR = 1.14, CI [1.03, 1.27]) were associated with an elevated risk for first cigarette use. Girls' reports of low parental monitoring also predicted first cigarette use (HR = 1.14, CI [1.06, 1.21]). CONCLUSIONS: Girls whose parents have limited awareness of their whereabouts and friends (i.e., low monitoring) are at an elevated risk for trying cigarettes, but parent-daughter differences in perceived awareness do not affect risk. By contrast, girls who perceive a lower degree of parental involvement than their parents do are at increased risk. Monitoring is one component of parenting that may reduce smoking risk; shared perspectives on the parent's level of involvement are similarly important.

With socioeconomic status controlled, cigarette use is lower among American Indians/Alaska Natives than whites.

BACKGROUND: Higher crude prevalence of cigarette use among American Indians/Alaska Natives (AI/AN) than non-Hispanic whites (NHW) has helped engender an assumption that race/ethnicity explains the difference. This study examines whether being AI/AN versus NHW predicts greater use when socioeconomic status and demographics are controlled. METHODS: Data came from the National Survey on Drug Use and Health (2013-2017). Using logistic regressions with socioeconomic (income, education) and demographic (gender, age, marital status) controls, differences between AI/AN (n = 4,305) and NHW (n = 166,348) regarding heavier cigarette use (past month daily use, past month use of 300+ cigarettes, and nicotine dependence) and current cigarette use (past month use plus 100+ cigarettes in lifetime) were assessed. Adjusted predicted probabilities were also constructed. RESULTS: NHW, compared to AI/AN, had greater odds of daily use: adjusted odds ratio (AOR) = 1.23 (95% CI: 1.03-1.49); predicted probabilities-15.3% and 13.0%, respectively. NHW had greater odds of using 300+ cigarettes: AOR = 1.47 (CI: 1.19-1.83); predicted probabilities-13.6% and 9.9%. NHW had greater odds of being nicotine dependent: AOR = 1.57 (CI: 1.31-1.89); predicted probabilities-10.3% and 7.1%. A difference in current use was not found. As controls, income and education were especially impactful. CONCLUSIONS: With controls, particularly for socioeconomic status, heavier cigarette use was lower among AI/AN than NHW, and a current cigarette use difference was not indicated. This contradicts the idea that being AI/AN versus NHW independently predicts greater cigarette use, and it underscores the importance of socioeconomic status for understanding cigarette use among AI/AN.

Smoking levels and associations between sociodemographic factors and smoking continuation in U.S. stroke survivors.

PURPOSE: Although stroke survivors who continue smoking face increased risk for subsequent strokes, little is known about U.S. poststroke smoking patterns. We examined smoking prevalence in U.S. stroke survivors and what sociodemographic factors are associated with continuation of smoking in these individuals. METHODS: We determined the prevalence of smoking in U.S. stroke survivors (n = 56,523) using 2016-2018 Behavioral Risk Factor Surveillance System data. A logistic regression was created to identify associations between sociodemographic factors and poststroke smoking continuation. RESULTS: 20.4% of stroke survivors continued to smoke after their stroke (14.7% smokes every day, 5.7% smokes some days). Older age, being male (OR: 1.15, 95% CI: 1.05-1.27), Asian (OR: 2.79, 95% CI: 1.52-5.11) or Hispanic (OR: 1.31, 95% CI: 1.06-1.63) ethnicity, higher income, higher educational attainment, and access to health care (OR: 1.27, 95% CI: 1.02-1.59) and a personal doctor (one doctor OR: 1.51, 95% CI: 1.25-1.83; more than one doctor OR: 1.59, 95% CI: 1.27-1.99) corresponded with increased odds of smoking continuation after a stroke. CONCLUSIONS: A greater push for smoking cessation by clinicians and support programs to aid with cessation in U.S. stroke survivors is needed to decrease the high prevalence of poststroke smoking in this population.
