Sex and Racial/Ethnic Patterns of Tobacco Product Use Among Students at a U.S. University in 2021-2023.

Background: Although the prevalence of conventional tobacco product use among U.S. college students has declined, an increasing number of students use various novel tobacco products. Objectives: This study aims to examine up-to-date sex and racial/ethnic patterns of tobacco use among students at a U.S. university in 2021-2023. Methods: Data of 2,732 students at an urban university in the Southeast of the U.S. were collected in 2021-2023 as part of the National College Health Assessment of the American College Health Association. Self-reported past 3-month use of five tobacco products (cigarette, electronic vapor products, water pipe/hookah, smokeless tobacco, and cigars) was dichotomized. We conducted multinomial logistic regression analysis to examine sex (male or female) and racial/ethnic (non-Hispanic White, non-Hispanic Black, Hispanic, or non-Hispanic Other) differences in single and dual/poly (con-current use of two or more tobacco products) tobacco use compared to nonuse, adjusting for age, student status, parent education level, obese status, psychological distress level, and survey year. Results: Male students had higher odds of being dual/poly tobacco user than female students, adjusting for covariates (adjusted odds ratio [AOR] = 2.00, 95% confidence interval [CI] = 1.42, 2.82). Non-Hispanic Black students had lower odds of being single (AOR = 0.43, 95% CI = 0.26, 0.69) and dual/poly (AOR = 0.09, 95% CI = 0.02, 0.37) tobacco user compared to non-Hispanic White students, adjusting for covariates. Conclusions: Considering higher health risk of con-current use of multiple tobacco products, dual/poly tobacco use prevention strategies targeting male and non-Hispanic White students may be considered.

Associations between gendered racism, racial identity, and nicotine use among Asian American men.

OBJECTIVES: The present study utilized an intersectional framework to examine if two forms of gendered racism, psychological emasculation and messages about Asian American men being undesirable partners, were associated with Asian American men's nicotine use. We also examined the potential mediating roles of two racial identity statuses, racial conformity and racial immersion. METHODS: A sample of 356 Asian American men living in the United States of America (USA) completed a cross-sectional survey via Qualtrics containing measures assessing the aforementioned constructs of interest. The primary analysis examined separate parallel mediation models, situating psychological emasculation and undesirable partner as separate independent variables, racial conformity and racial immersion as parallel mediators, nicotine use as the outcome, and age and employment as covariates. RESULTS: In separate parallel mediation models, the links between psychological emasculation and undesirable partner on one hand, and nicotine use on the other, were completely mediated only by racial conformity, and not significantly mediated by racial immersion. Specifically, greater endorsement of gendered racism was associated with greater conformity with (and internalization of) these gendered racist beliefs, which in turn were associated with greater nicotine use. CONCLUSION: Researchers and practitioners may consider racial conformity as an interventional target to ameliorate Asian American men's nicotine use. Future studies should continue to examine other culturally relevant and/or potentially protective constructs (e.g., on the basis of gender, race, and its intersection) that may mitigate Asian American men's nicotine use.

The Association between State-Level Structural Racism and Alcohol and Tobacco Use Behaviors among a National Probability Sample of Black Americans.

BACKGROUND: Structural racism is how society maintains and promotes racial hierarchy and discrimination through established and interconnected systems. Structural racism is theorized to promote alcohol and tobacco use, which are risk factors for adverse health and cancer-health outcomes. The current study assesses the association between measures of state-level structural racism and alcohol and tobacco use among a national sample of 1,946 Black Americans. METHODS: An existing composite index of state-level structural racism including five dimensions (subscales; i.e., residential segregation and employment, economic, incarceration, and educational inequities) was merged with individual-level data from a national sample dataset. Hierarchical linear and logistic regression models, accounting for participant clustering at the state level, assessed associations between structural racism and frequency of alcohol use, frequency of binge drinking, smoking status, and smoking frequency. Two models were estimated for each behavioral outcome, one using the composite structural racism index and one modeling dimensions of structural racism in lieu of the composite measure, each controlling for individual-level covariates. RESULTS: Results indicated positive associations between the incarceration dimension of the structural racism index and binge drinking frequency, smoking status, and smoking frequency. An inverse association was detected between the education dimension and smoking status. CONCLUSIONS: Results suggest that state-level structural racism expressed in incarceration disparities, is positively associated with alcohol and tobacco use among Black Americans. IMPACT: Addressing structural racism, particularly in incarceration practices, through multilevel policy and intervention may help to reduce population-wide alcohol and tobacco use behaviors and improve the health outcomes of Black populations.

Births: Final Data for 2019.

Objectives-This report presents 2019 data on U.S. births according to a wide variety of characteristics. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. Methods-Descriptive tabulations of data reported on the birth certificates of the 3.75 million births that occurred in 2019 are presented. Data are presented for maternal age, livebirth order, race and Hispanic origin, marital status, tobacco use, prenatal care, source of payment for the delivery, method of delivery, gestational age, birthweight, and plurality. Selected data by mother's state of residence and birth rates by age are also shown. Trend data for 2010 through 2019 are presented for selected items. Trend data by race and Hispanic origin are shown for 2016-2019. Results-A total of 3,747,540 births were registered in the United States in 2019, down 1% from 2018. The general fertility rate declined from 2018 to 58.3 births per 1,000 women aged 15-44 in 2019. The birth rate for females aged 15-19 fell 4% between 2018 and 2019. Birth rates declined for women aged 20-34 and increased for women aged 35-44 for 2018-2019. The total fertility rate declined to 1,706.0 births per 1,000 women in 2019. Birth rates declined for both married and unmarried women from 2018 to 2019. The percentage of women who began prenatal care in the first trimester of pregnancy rose to 77.6% in 2019; the percentage of all women who smoked during pregnancy declined to 6.0%. The cesarean delivery rate decreased to 31.7% in 2019 (Figure 1). Medicaid was the source of payment for 42.1% of all births in 2019. The preterm birth rate rose for the fifth straight year to 10.23% in 2019; the rate of low birthweight was essentially unchanged from 2018 at 8.31%. Twin and triplet and higher-order multiple birth rates both declined in 2019 compared with 2018.

Patterns of Tobacco Use and Related Protective Factors Among Somali Youth in the United States.

Anti-smoking norms and educational aspirations are established tobacco prevention targets for general United States (U.S.) adolescent populations but protective factors remain poorly characterized for Somali-American youth. Here we describe patterns of past 30-day tobacco use and associated protective factors among eighth, ninth, and eleventh grade Somali adolescent respondents (n = 2009) to the 2016 Minnesota Student Survey using multivariate logistic regressions. E-cigarette (5.7%) and hookah (5.0%) use were most prevalent. Male youth reported higher levels of tobacco use across products. Adjusted odds ratios showed that internal developmental assets (e.g., e-cigarettes aOR 0.37, 95% CI 0.37, 0.79) and parental anti-smoking norms (e.g., e-cigarettes aOR 0.19, 95% CI 0.09, 0.38) protected against use of all tobacco products. E-cigarettes and hookah are prevalent among U.S. Somali youth, highlighting the need for prevention efforts that address emerging tobacco products and leverage protective factors such as internal assets and parental anti-smoking norms.

Heated Tobacco Products Have Reached Younger or More Affluent People in Japan.

BACKGROUND: The trend of the diffusion of heated tobacco products (HTPs) is a great concern because HTPs have become available worldwide. This study examined the sociodemographic characteristics of HTPs users in Japan, where HTPs were first launched. METHODS: This cross-sectional study used data from an online survey conducted in 2017. A total of 4,926 participants, aged 20-69 years, were included. The dependent variable was the type of tobacco products used. The independent variables were age and equivalent income. Two analyses estimated the odds ratios (ORs) for 1) being smokers compared to "non-smokers," and 2) being "HTP smokers" compared to "only combustible cigarette smokers." Analyses were stratified by sex. Educational attainment and occupation were also used in the sensitivity analyses. RESULTS: The percentages of "non-smokers," "only combustible cigarette smokers," and "HTP smokers" were 82.8%, 14.2%, and 3.0%, respectively. When compared to the oldest participants (aged 60-69), the youngest participants (aged 20-29) tended to be "HTP smokers" (OR 7.90; 95% confidence interval [CI], 3.09-20.22 for men and OR 9.28; 95% CI, 2.14-40.28 for women). Compared to participants with the lowest incomes (<2 million), those with the highest incomes (≥4 million) tended to use HTPs (OR 2.93; 95% CI, 1.56-5.49 in men and OR 1.82; 95% CI, 0.73-4.54 in women). These trends were consistent when analyses included only smokers. There were consistent results in other SES measurements, including educational attainment and occupation. CONCLUSIONS: Younger or more affluent people tended to use HTPs, although smoking rates among these populations were generally lower. New tobacco control efforts are required.

Consumption of Alcohol, Tobacco and Psychoactive Substances in Adolescents from an Indigenous Territory in the Colombian Amazon. / Consumo de alcohol, tabaco y sustancias psicoactivas de los adolescentes de un territorio indígena en la Amazonía colombiana.

INTRODUCTION: There are very few studies on the consumption of psychoactive substances (PAS) among young people from indigenous territories and evening or blended learning students. In Inírida, a municipality in the Colombian Amazon, there were concerns about a possible consumption issue that had never been characterised before. OBJECTIVE: To characterise the consumption of alcohol, tobacco and PAS in Inírida among teenage evening and blended learning students. METHODS: The Inter-American Uniform Drug Use Data System (SIDUC) survey developed by the Inter-American Drug Abuse Control Commission (CICAD) was adapted to the cultural context and carried out on 95% of 284 evening and blended learning students (262). Descriptive statistics and multiple correspondence analyses were used. RESULTS: Currently, 59% consume alcohol; 28% tobacco; 21% marijuana; 3% cocaine paste; 1% ecstasy (MDMA); 1% cocaine; and 1% inhalants. Also, 61% believe that drugs are available inside and around the vicinity of their school, and that marijuana (62%) and cocaine paste (35%) are easily acquired. Drugs are most commonly offered in neighbourhoods (56%) and at parties (30%). Those offering the highest quantity of drugs are acquaintances (35%) and friends (29%). And 51% stated that they had participated in preventive activities related to consumption. CONCLUSIONS: The population has a higher consumption of the substances studied in comparison with the national reference, that of Orinoquía and Amazonía, with the exception of cocaine and inhalants. The consumption situation was confirmed, so participatory actions are proposed.

Change in health profile of refugees resettling in New Zealand, 1980-2014.

AIM: To update data previously published on the health profile of the refugees resettling in New Zealand, and to draw attention to the change in health profile over time, with a decline of infectious disease/deficiencies, and a rise of non-communicable diseases, a worldwide phenomenon. METHOD: Comparative data was extracted from (1) written annual reports prepared by medical officers at the Mangere Refugee Resettlement Centre (1978-1991), (2) a Microsoft ACCESS patient management system between 1995 and 1999 and (3) a MEDTECH patient management system between 2010 and 2014. RESULTS: Over the period 1979-2014, the rate of infectious diseases has declined markedly in resettling refugees, and the rate of non-communicable diseases has increased. For example, the incidence of tuberculosis has decreased from 4% to 0.2%, gut parasites from more than 40% to, in some intakes, 15% and iron deficiency from 22% to 10%, while the diabetes rate has gone from 0.1% to 2.7%. CONCLUSION: While management of unfamiliar infectious diseases and deficiencies (especially vitamin D) still remains an important part of the management of refugee health, their management usually involves limited time and expense, and their burden is much less than before. However, refugees now resettling in New Zealand and the rest of the world often present with familiar non-communicable diseases that require long-term management.

Tobacco and Alcohol Use Among Ethnic Minorities in Vietnam.

This study investigates the prevalence of tobacco and alcohol uses and associated factors among 12 ethnic minorities in Vietnam in 2019. A cross-sectional survey was conducted among 5172 people aged ≥15 years. The prevalence of smoking and drinking was 19.7% and 29.9%, respectively, and significantly higher among men than women. These numbers were heterogeneous across ethnic minorities. Smoking prevalence was high among Ba Na (25.9%), Cham An Giang (22.3%), Khmer (23.5%), La Hu (26.3%), Ta Oi (30.7%), and Bru Van Kieu (29.6%) ethnicities whereas that of Gie Trieng and Mnong ethnicities was low (3.7% and 9.5%, respectively). Drinking prevalence ranged from 1.4% in Cham An Giang ethnicity to 68.6% in Ba Na ethnicity. A wide ethnic disparity on tobacco and alcohol use could be explained by the ethnic variation of lifestyles, social norms, and cultural features. Our findings suggest the need to develop ethnic-specific interventions to mitigate the smoking and drinking prevalence.

Discrimination Is Associated with Elevated Cardiovascular Disease Risk among African Immigrants in the African Immigrant Health Study.

Background: African Americans and other persons of African descent in the United States are disproportionately affected by cardiovascular diseases (CVD). Discrimination is associated with higher CVD risk among US adults; however, this relationship is unknown among African immigrants. Methods: The African Immigrant Health Study was a cross-sectional study of African immigrants in Baltimore-Washington, DC, with recruitment and data collection taking place between June 2017 and April 2019. The main outcome was elevated CVD risk, the presence of ≥3 CVD risk factors including hypertension, diabetes, high cholesterol, overweight/obesity, tobacco use, and poor diet. The secondary outcomes were these six individual CVD risk factors. The exposure was discrimination measured with the Everyday Discrimination Scale; summed scores ≥2 on each item indicated frequent experiences of discrimination. Resilience was assessed with the 10-item Connor-Davidson resilience scale. Logistic regression was used to examine the odds of elevated CVD risk, adjusting for relevant covariates. Results: We included 342 participants; 61% were females. The mean (±SD) age was 47(±11) years, 61% had at least a bachelor's degree, 18% had an income <$40,000, and 49% had lived in the US ≥15 years. Persons with frequent experiences of discrimination were 1.82 times (95%CI: 1.04-3.21) more likely to have elevated CVD risk than those with fewer experiences. Resilience did not moderate the relationship between CVD risk and discrimination. Conclusion: African immigrants with frequent experiences of discrimination were more likely to have elevated CVD risk. Targeted and culturally appropriate interventions are needed to reduce the high burden of CVD risk in this population. Health care providers should be aware of discrimination as a meaningful social determinant of CVD risk. At the societal level, policies and laws are needed to reduce the occurrence of discrimination among African immigrants and racial/ethnic minorities.

Recruitment best practices of a cardiovascular risk reduction randomised control trial in rural Alaska Native communities.

Though not native to Alaska, tobacco use is common among Alaska Native people in the Norton Sound region, an area consisting of 16 communities with population size 107 to 3,695. We summarise best practices in recruiting Alaska Native adults who smoke for a randomised controlled tobacco treatment trial. Participants were Alaska Native, 19 years and older, smoking daily, with hypertension and/or high cholesterol, residing in the Norton Sound region of Alaska. Study staff travelled to the remote communities to recruit, typically staying 5 days. Screening and enrolment success was examined by day, season, and staffing level. From June 2015 - December 2018, the study team made 122 trips, screening 1089 individuals and enrolling 314 participants. In the field, days 2-3 (51%) were best for screening, while days 3-4 (53%) had the greatest enrolment. Community size correlated with enrolment (r = 0.83, p <.001). Recruitment was optimised in spring and with multiple staff in the field. Despite challenges (e.g., harsh weather, poor internet connectivity), with active outreach (e.g. tabling in busy areas, attending community events, utilising mixed media, collaborating with clinic staff), the project reached its recruitment goal. Study findings can inform community-based tobacco treatment research trials in remote areas.

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.

Association of Socioeconomic Status and Comorbidities with Racial Disparities during Kidney Transplant Evaluation.

BACKGROUND AND OBJECTIVES: Black patients referred for kidney transplantation have surpassed many obstacles but likely face continued racial disparities before transplant. The mechanisms that underlie these disparities are unclear. We determined the contributions of socioeconomic status (SES) and comorbidities as mediators to disparities in listing and transplant. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We studied a cohort (n=1452 black; n=1561 white) of patients with kidney failure who were referred for and started the transplant process (2009-2018). We estimated the direct and indirect effects of SES (self-reported income, education, and employment) and medical comorbidities (self-reported and chart-abstracted) as mediators of racial disparities in listing using Cox proportional hazards analysis with inverse odds ratio weighting. Among the 983 black and 1085 white candidates actively listed, we estimated the direct and indirect effects of SES and comorbidities as mediators of racial disparities on receipt of transplant using Poisson regression with inverse odds ratio weighting. RESULTS: Within the first year, 876 (60%) black and 1028 (66%) white patients were waitlisted. The relative risk of listing for black compared with white patients was 0.76 (95% confidence interval [95% CI], 0.69 to 0.83); after adjustment for SES and comorbidity, the relative risk was 0.90 (95% CI, 0.83 to 0.97). The proportion of the racial disparity in listing was explained by SES by 36% (95% CI, 26% to 57%), comorbidity by 44% (95% CI, 35% to 61%), and SES with comorbidity by 58% (95% CI, 44% to 85%). There were 409 (42%) black and 496 (45%) white listed candidates transplanted, with a median duration of follow-up of 3.9 (interquartile range, 1.2-7.1) and 2.8 (interquartile range, 0.8-6.3) years, respectively. The incidence rate ratio for black versus white candidates was 0.87 (95% CI, 0.79 to 0.96); SES and comorbidity did not explain the racial disparity. CONCLUSIONS: SES and comorbidity partially mediated racial disparities in listing but not for transplant.

Do tobacco industry websites target content to specific demographic groups?

BACKGROUND: Prior research has not examined whether tobacco brand websites vary content based on audience demographics. This study explored whether marketing content on tobacco brand websites varied by user ethnicity, gender or age group. METHODS: Participants (n = 32) were adult smokers, representing equal numbers of eight demographic groups: user ethnicity (Non-Hispanic White, Hispanic, African American, Asian), gender (women, men) and age (age 21-35, age 36+). This study examined 12 tobacco brand websites representing four tobacco product categories (cigarettes, cigar/cigarillos, smokeless tobacco, and e-cigarettes). From January 2016 to January 2017, participants coded websites for themes, interactive activities, and links to social media sites (n = 874 website visits). Logistic regression was used to analyze observed content by participant ethnicity, age and gender. RESULTS: All themes, all interactive activities and all links to social media were observed at least once for each demographic category. Male participants were more likely to observe Harm reduction themes, while female participants were more likely to observe Promotion themes. Older participants were more likely to observe website features allowing them to select music, and request coupons. Compared to Non-Hispanic White participants, African American participants were more likely to observe links to social media sites. CONCLUSION: Tobacco brand website content varied across ethnic, age and gender groups. These findings suggest that other factors, such as tobacco use behaviors, may influence marketing strategies participants recall or find appealing. The findings from this study can inform future regulatory activities and communication strategies aimed at countering pro-tobacco content online.

Racial differences in alcohol and tobacco use in adolescence and mid-adulthood in a community-based sample.

PURPOSE: Smoking and alcohol use have been posited as possible contributors to racial health disparities, despite higher smoking and alcohol use among non-Hispanic White youth and young adults compared to Blacks. To further investigate this claim, we aim to assess variation in alcohol and cigarette use across two distinct points of the life course. METHOD: Data are from a subset of 559 (279 male, 280 female) self-identified Black and White participants of the Child Health and Development study. Self-report alcohol and cigarette use were collected between age 15-17 and at mean age 50. Logistic regressions were estimated; supplementary analyses adjusted for maternal age, prenatal smoking, household income, childhood SES, and education. RESULTS: White participants were more likely to drink regularly (Odds ratio (OR) 2.2; 95%CI 1.2, 4.0) and be intoxicated (OR 2.0; 95%CI 1.2, 3.2) in adolescence compared with Blacks. In mid-adulthood, Whites remained more likely to currently drink (OR 2.3; 95%CI 1.6, 3.4) but among drinkers, less likely to binge drink (OR 0.4; 95%CI 0.2, 0.8). White participants were less likely to smoke in mid-adulthood (OR 0.4; 95%CI 0.3, 0.6), but among smokers, were more likely to smoke ≥ ½ a pack per day (OR 3.4; 95%CI 1.5, 7.8). CONCLUSIONS: Blacks were less likely to engage in drinking across the life course, but, among drinkers, more likely to binge drink in mid-adulthood. Blacks were more likely to smoke in mid-adulthood, but smoked infrequently compared with Whites. These patterns suggest that a reframing of disparities mechanisms to focus on broader structural and social factors may benefit progress in understanding and ameliorating inequities.

Noncommunicable Diseases Among Syrian Refugees in Turkey: An Emerging Problem for a Vulnerable Group.

Turkey hosts 3.6 million Syrian refugees, which is the highest number of refugees in a single country worldwide. In this study, we examined the status of noncommunicable diseases and their risk factors among Syrian refugees in Turkey. The data for the study come from the 2016 Health Status Survey of Syrian Refugees in Turkey. We used logistic regression and descriptive statistics to analyze four major noncommunicable diseases and their risk factors to assess the health status of Syrians under temporary protection in Turkey. Combined risk factor analysis showed that, as age increases, the risk of having a noncommunicable disease increases: Syrians in Turkey 60-69 years old have the highest risk of noncommunicable diseases followed by those 45-59 years old. Men have a higher risk of noncommunicable diseases than women. The noncommunicable disease status of Syrians in Turkey should be considered given the high economic burden of treatment and the potential length of stay of Syrians in Turkey.

Smokefree leadership among the Yolŋu peoples of East Arnhem Land, Northern Territory: a qualitative study.

This qualitative study examined smokefree leadership among the Yolŋu people, Indigenous landowners of East Arnhem Land. Despite disproportionately high smoking prevalence, the study found that most people enacted smokefree leadership within families and communities. While there was broad concern about not impinging on the autonomy of others, Indigenous health workers regularly advised clients, family and community members to quit smoking. This followed a general belief that the issue of smoking was best raised by health workers, rather than traditional leaders. Protecting children from second-hand smoke and preventing smoking initiation was important to all participants irrespective of their smoking status. An enduring and highly valued cultural connection to ŋarali' (tobacco) remains an essential part of the sacred practices of the funeral ceremony, an important and unique social utility. The study found consensus among participants that this would not change. Navigating traditional connections to ŋarali' in a context where most people are still addicted to commercial tobacco is challenging and requires respectful and culturally compelling approaches. Tobacco control initiatives with the Yolŋu should therefore utilise existing smokefree leaders within the social context in which ŋarali' is valued and used, an approach that may resonate with other Indigenous Australian nations and communities.

Modeling Heterogeneous Peer Assortment Effects Using Finite Mixture Exponential Random Graph Models.

This article develops a class of models called sender/receiver finite mixture exponential random graph models (SRFM-ERGMs). This class of models extends the existing exponential random graph modeling framework to allow analysts to model unobserved heterogeneity in the effects of nodal covariates and network features without a block structure. An empirical example regarding substance use among adolescents is presented. Simulations across a variety of conditions are used to evaluate the performance of this technique. We conclude that unobserved heterogeneity in effects of nodal covariates can be a major cause of misfit in network models, and the SRFM-ERGM approach can alleviate this misfit. Implications for the analysis of social networks in psychological science are discussed.

Attitudes toward tobacco among low-income Hispanic adolescents: Implications for prevention.

Background: Although US cigarette smoking rates have steadily declined, the changing nature of nicotine consumption and the popularity of non-combustible nicotine products urges us to revise tobacco prevention strategies. Research on smoking perspectives among Hispanic youth is limited yet crucial for prevention efforts with Hispanics being the largest minority in the U.S.Objective: This study sought to understand the experience and perceptions of low-income Hispanic youth regarding tobacco use.Methods: Forty-nine adolescents (ages 9 to 19) from El Paso, Texas, participated in five extended focus group discussions about tobacco/nicotine use.Results: Adolescents were predominantly exposed to tobacco through relatives, although school and party contexts became more relevant as youth aged. Youth had negative perceptions of tobacco and smokers, but believed their peers often viewed tobacco positively. Youth also saw tobacco use as a functional stress-management strategy, especially within their extended family. Health and family were strong motivators not to smoke.Conclusions: Youth maintain several tensions in their views on tobacco. Tobacco use is considered unpleasant and harmful, yet youth perceive their peers to view it as cool. Peer to peer discussion of tobacco experiences and perceptions may help correct these incongruent viewpoints. Adding to this tension is the perception that tobacco is used to manage stress. Given the importance of the home environment for Hispanic youth, tobacco prevention efforts may benefit from engaging family to identify the ways in which tobacco use causes stress.

Examining the internalizing pathway to substance use frequency in 10 cultural groups.

Use of alcohol, tobacco, and drugs (i.e., substance use) is a leading cause of global health burden for 10-to-24-year-olds, according to the World Health Organization's index of number of years of life lost, leading international health organizations to prioritize the prevention of substance use before it escalates in adolescence. Pathways defined by childhood externalizing symptoms and internalizing symptoms identify precursors to frequent substance use toward which interventions can be directed. However, these pathways are rarely examined beyond the United States and Europe. We investigated these pathways in our sample of 1083 children from 10 cultural groups followed from ages 8-14. We found that age-10 externalizing symptoms predicted more frequent mother-reported age-13 and self-reported age-14 substance use. We also found that a depressive pathway, marked by behavioral inhibition at age 8 and subsequent elevation in depressive symptoms across ages 8-12 predicted more frequent substance use at age 13 and 14. Additionally, we found a combined externalizing and internalizing pathway, wherein elevated age-9 depressive symptoms predicted elevated externalizing symptoms at age-10 which predicted greater peer support for use at age-12, which led to more frequent substance use at age-13 and -14. These pathways remained significant within the cultural groups we studied, even after controlling for differences in substance use frequency across groups. Additionally, cultures with greater opportunities for substance use at age-12 had more frequent adolescent substance use at age-13. These findings highlight the importance of disaggregating between- and within-culture effects in identifying the etiology of early adolescent substance use.
