Racial/ethnic differences in the acute effects of reduced nicotine content cigarettes among adolescents who smoke

OBJECTIVE

Reducing the nicotine content in cigarettes decreases their addictiveness and abuse liability, including among adolescents. Whether these effects differ by race/ethnicity is unknown. This study is a secondary analysis of previously published data collected between 2014-2017. We examined racial/ethnic differences in the effects of smoking cigarettes with varying nicotine content levels on subjective effects and tobacco withdrawal among adolescents who smoke daily.

METHODS

Across two counterbalanced sessions, 50 adolescents recruited from Rhode Island (ages 15-19; 30 % Underrepresented Minorities [URM], 20 % Asians and Pacific Islanders [API]; 50 % Non-Hispanic Whites) self-administered a very low nicotine content (VLNC; 0.4 mg nicotine/g of tobacco) or normal nicotine content control (NNC; 15.8 mg/g) research cigarette following overnight abstinence. Subjective effects were reported post-administration and tobacco withdrawal outcomes were calculated from pre- to post-administration scores. Multilevel linear models tested main and interactive effects between cigarette nicotine content and race/ethnicity on all study outcomes.

RESULTS

Participants reported lower positive subjective effects and reductions in smoking urges after smoking a VLNC cigarette relative to smoking an NNC cigarette (ps < 0.01). A main effect of race/ethnicity emerged, such that API (vs. URM and White) adolescents reported lower positive subjective effects, greater craving reduction, and higher cigarette aversion after smoking, regardless of nicotine content (ps < 0.05). Significant interactions were found between race/ethnicity and nicotine content for cigarette aversion, such that API adolescents rated VLNC (vs. NNC) cigarettes as less aversive than White and URM adolescents did (p = 0.03).

CONCLUSIONS

Findings provide evidence that VLNC cigarettes may reduce abuse liability and tobacco withdrawal symptoms for adolescents across racial/ethnic groups and particularly for API youth.

Adult Familial Influences on Rural Native Hawaiian and Pacific Islander Youths' E-Cigarette Use

Background: Over the past decade, youth e-cigarette use has grown into a national epidemic, with Native Hawaiian and Pacific Islander (NHPI) youths' rates among some of the highest in the nation. Family factors significantly contribute to NHPI youths' decisions to engage in or resist substance use, yet few studies have specifically examined familial influences on NHPI youths' substance use decision-making and behaviors. Objective: The objective of this study is to examine adult familial influences on rural NHPI youths' decisions to engage in e-cigarette use. Method: Seventeen gender-specific focus groups with NHPI youths (N = 69) from eight public schools on Hawai'i Island were conducted. Results: Two family-related themes emerged from the data: 1) parental substance use permissiveness, and 2) family normalization of e-cigarette use. Conclusions: Examining adult familial contributors to NHPI youths' e-cigarette use needs to be part of a comprehensive effort to address NHPI health and substance use disparities. Prevention interventions should be explicit in addressing the family and relational context of NHPI youths' substance use.

Tobacco use among native Hawaiian and Pacific Islander youth in the U.S. and USAPI: a systematic review of the literature

With rates of tobacco use among youth in the United States on the rise, further analysis of disproportionately impacted populations, like Native Hawaiian and other Pacific Islanders (NHPIs), is needed. NHPIs face a unique set of challenges compared to other ethnic minorities that contribute to their health disparities from tobacco use. This systematic literature review investigated empirical studies published between 2010-2020 on tobacco use among NHPI youth and young adults. Using comprehensive literature search engines and focused author searches of tobacco researchers in NHPI communities, 7,208 article abstracts were extracted for potential inclusion. Explicit inclusionary and exclusionary criteria were used to identify peer-reviewed articles related to tobacco use correlates and interventions for NHPI youth populations. A total of 17 articles met our criteria for inclusion in this study. Community influences, peer pressure, social status, variety of flavors, craving, and stimulation were correlates found in smoking and vaping for NHPI youth. There were also few published tobacco use prevention and intervention studies focused specifically on NHPI youth. Our study addresses the needs of an under-researched population that is heavily affected by the adverse consequences of short-term and long-term use of cigarettes and e-cigarettes. Additional research should focus on developing effective and culturally relevant interventions to reduce NHPI health disparities.

Correlates of tobacco use among Asian and Pacific Islander youth and young adults in the U.S.: A systematic review of the literature

Rates of tobacco product use, including the use of combustible and electronic cigarettes, remain high in youth and young adults within the U.S. Though a substantial body of work has examined risk factors associated with initiation and ongoing use of tobacco products, research on tobacco use and associated correlates among Asian and Pacific Islanders (APIs) has been more limited despite high rates in select API subgroups. This systematic review outlines recent research (2010-2020) on the correlates of tobacco use in APIs aged 9-29. To better understand determinants of tobacco use and identify gaps in the literature, we framed correlates based on the National Institute on Minority Health and Health Disparities (NIMHD) multidimensional research framework. Database and author-focused searches were conducted, followed by article abstract and full-text reviews, much of which were guided by a discrete set of inclusionary and exclusionary criteria related to tobacco use and youth/young adults. A total of 24 articles were included in this review. The majority of articles focused on individual-level correlates, with a high number of studies demonstrating association between behavioral and sociocultural factors and tobacco product use behavior. Interpersonal factors also made up a substantial portion of the literature, commonly focusing on peer, family, and social norms. Gaps related to the NIMHD model are addressed. Future research should examine biological and community/societal factors associated with API smoking to better understand unique correlates in this population and to inform tobacco prevention and intervention approaches.

The implementation of a culturally grounded, school-based, drug prevention curriculum in rural Hawai'i

This article describes the process of infusing implementation strategies in the development of a school-based drug prevention curriculum for rural Native Hawaiian youth. The curriculum (Ho'ouna Pono) is a video-enhanced, teacher-implemented curriculum developed using a culturally grounded and community-based participatory research approach. Throughout the development of the curriculum, strategies reflective of the domains of the Consolidated Framework for Implementation Research (CFIR) were integrated into the teacher training manual, to promote the implementation, adoption, and sustainability of the curriculum in rural Hawai'i. These strategies were validated through qualitative data across two interrelated studies with community stakeholders in rural Hawai'i. Implications for prevention, community, and educational practices are described in this article.

An Efficacy Trial of the Ho'ouna Pono Drug Prevention Curriculum: An Evaluation of a Culturally Grounded Substance Abuse Prevention Program in Rural Hawai'i

This study reports on the drug use outcomes in an efficacy trial of a culturally grounded, school-based, substance abuse prevention curriculum in rural Hawai'i. The curriculum (Ho'ouna Pono) was developed through a series of pre-prevention and pilot/feasibility studies funded by the National Institute on Drug Abuse, and focuses on culturally relevant drug resistance skills training. The present study used a dynamic wait-listed control group design (Brown, Wyman, Guo, & Pena, 2006), in which cohorts of middle/intermediate public schools on Hawai'i Island were exposed to the curriculum at different time periods over a two-year time frame. Four-hundred and eighty six youth participated in the study. Approximately 90% of these youth were 11 or 12 years of age at the start of the trial. Growth curve modeling over six waves of data was conducted for alcohol, marijuana, cigarettes/e-cigarettes, crystal methamphetamine, and other hard drugs. The findings for alcohol use were contrary to the hypothesized effects of the intervention, but may have been a reflection of a lack equivalence among the cohorts in risk factors that were unaccounted for in the study. Despite this issue, the findings also indicated small, statistically significant changes in the intended direction for cigarette/e-cigarette and hard drug use. The present study compliments prior pilot research on the curriculum, and has implications for addressing Native Hawaiian and Pacific Islander health disparities.

An Evaluation of the Ho'ouna Pono Curriculum: A Pilot Study of Culturally Grounded Substance Abuse Prevention for Rural Hawaiian Youth

This pilot study evaluated the Ho'ouna Pono curriculum, which is a culturally grounded, school-based, drug prevention curriculum tailored to rural Native Hawaiian youth. The curriculum focuses on culturally relevant drug resistance skills training and is aligned with the State of Hawai'i academic standards. Six Hawai'i Island public middle/intermediate schools randomly assigned to intervention or treatment-as-usual comparison conditions (N = 213) were evaluated in this study. Paired sample t-tests separating intervention and comparison groups were conducted, as well as mixed models that adjusted for random effects (nesting) at the school level. Findings suggested that the curriculum was effective in maintaining youths' use of culturally relevant drug resistance skills, as well as decreasing girls' aggressive behaviors, at six-month follow-up. Unanticipated findings also suggested areas for curricular improvement, including more emphasis on normative drug education. Implications for future research and development of the curriculum are discussed.

Involuntary Tobacco Smoking Exposure Among Korean American Emerging Adults: A Qualitative Study

High smoking prevalence among Korean American (KA) males place KA family members and co-workers at an elevated risk of involuntary tobacco smoke exposure (ITSE). KA emerging adults (EAs) face an additional risk of ITSE by their peers, as emerging adulthood is associated with increased smoking. This paper explores health behaviors, attitudes and beliefs of ITSE among KAEA. Qualitative data analysis was conducted on transcripts from ten focus groups (N = 67). Themes related to attitudes and perceptions of ITSE were identified: high level of cultural tolerance, lack of knowledge/insufficient information, perceived benign health effects, and perceived hopelessness/indifference. Themes related to culturally-held beliefs include: tolerance of male family smokers, allowance of indoor smoking and misconceptions of practices perceived to minimize ITSE. The dissemination of culturally relevant ITSE information is needed in KA communities. Failure to implement indoor smoking bans in ethnic enclaves calls for increased enforcement of regulations by public health officials.

The Social Contexts of Drug Offers and Their Relationship to Drug Use of Rural Hawaiian Youth

This paper examines the differences in drug offers and recent drug use between Hawaiian and non-Hawaiian youth residing in rural communities, and the relationship between drug offers and drug use of Hawaiian youth in these communities. Two hundred forty nine youth (194 Hawaiian youth) from 7 different middle or intermediate schools completed a survey focused on the social context of drug offers. Hawaiian youth in the study received significantly more offers from peers and family, and had significantly higher rates of recent alcohol and marijuana use, compared with non-Hawaiian youth. Logistic regression analysis indicated that the social context differentially influenced drug use of Hawaiian youth, with family drug offers and context influencing overall drug use and the use of the widest variety of substances. Implications for prevention practices are discussed.

Developing empirically based, culturally grounded drug prevention interventions for indigenous youth populations

This article describes the relevance of a culturally grounded approach toward drug prevention development for indigenous youth populations. This approach builds drug prevention from the "ground up" (i.e., from the values, beliefs, and worldviews of the youth that are the intended consumers of the program) and is contrasted with efforts that focus on adapting existing drug prevention interventions to fit the norms of different youth ethnocultural groups. The development of an empirically based drug prevention program focused on rural Native Hawaiian youth is described as a case example of culturally grounded drug prevention development for indigenous youth; the impact of this effort on the validity of the intervention and on community engagement and investment in the development of the program are discussed. Finally, implications of this approach for behavioral health services and the development of an indigenous prevention science are discussed.

Two-year outcomes of a randomized, family-based substance use prevention trial for Asian American adolescent girls

Asian Americans have been largely ignored in the prevention outcome literature. In this study, we tested a parent-child program with a sample of Asian American adolescent girls and their mothers, and evaluated the program's efficacy on decreasing girls' substance use and modifying risk and protective factors at individual, family, and peer levels. A total of 108 Asian American mother-daughter dyads recruited through online advertisements and from community service agencies were randomly assigned to an intervention arm (n = 56) or to a test-only control arm (n = 52). The intervention consisted of a nine-session substance abuse prevention program, delivered entirely online. Guided by family interaction theory, the prevention program aimed to strengthen the quality of girls' relationships with their mothers while increasing girls' resilience to resist substance use. Intent-to-treat analyses showed that at 2-year follow-up, intervention-arm dyads had significantly higher levels of mother-daughter closeness, mother-daughter communication, maternal monitoring, and family rules against substance use compared with the control-arm dyads. Intervention-arm girls also showed sustained improvement in self-efficacy and refusal skills and had lower intentions to use substances in the future. Most important, intervention-arm girls reported fewer instances of alcohol and marijuana use and prescription drug misuse relative to the control-arm girls. The study suggests that a culturally generic, family-based prevention program was efficacious in enhancing parent-child relationships, improving girls' resiliency, and preventing substance use behaviors among Asian American girls.

The development of videos in culturally grounded drug prevention for rural native Hawaiian youth

The purpose of this study was to adapt and validate narrative scripts to be used for the video components of a culturally grounded drug prevention program for rural Native Hawaiian youth. Scripts to be used to film short video vignettes of drug-related problem situations were developed based on a foundation of pre-prevention research funded by the National Institute on Drug Abuse. Seventy-four middle- and high-school-aged youth in 15 focus groups adapted and validated the details of the scripts to make them more realistic. Specifically, youth participants affirmed the situations described in the scripts and suggested changes to details of the scripts to make them more culturally specific. Suggested changes to the scripts also reflected preferred drug resistance strategies described in prior research, and varied based on the type of drug offerer described in each script (i.e., peer/friend, parent, or cousin/sibling). Implications for culturally grounded drug prevention are discussed.

A community stakeholder analysis of drug resistance strategies of rural native Hawaiian youth

This study examines and validates the drug resistance strategies identified by rural Hawaiian youth from prior research with a sample of community stakeholders on the Island of Hawai'i. One hundred thirty-eight stakeholders with a vested interest in reducing youth substance use (i.e., teachers, principals, social service agency providers, and older youth) completed a web-based survey comprised of 15 drug-related problem situations and 413 responses developed by Hawaiian youth. The findings corroborated the youth-focused findings from prior research. Differences in the endorsement of different strategies were examined based on gender, ethnicity, and age of the stakeholders. Implications for culturally grounded drug prevention in rural Hawaiian communities are discussed.

Substance use among Asian-American adolescents: perceptions of use and preferences for prevention programming

Rarely has substance use prevention programming targeted Asian-American adolescents. Using a focus group methodology, we explored perceptions of substance use and preferences for prevention programming among 31 Asian-American adolescents in New York City. Participants considered substance use common in the community. Factors contributing to substance use among Asian-American adolescents (e.g., peer pressure, pressure to achieve, family factors, and community influence) were identified, and the need for prevention programs tailored for the Asian-American community was highlighted. Participants discussed preferred program content, delivery settings, and recruitment and retention strategies. Despite the favorable attitude for family-based prevention programming, participants raised potential issues concerning the feasibility of such a program. Study findings facilitate understanding of Asian-American adolescents' substance use behavior and shed light on prevention program development for this underserved population.

A review of the literature on Native Hawaiian youth and drug use: implications for research and practice

This article provides a comprehensive review of the recent literature on Native Hawaiian youth and substance use. Eight-hundred and twelve potential articles pertaining to Native Hawaiian youth and substance use published between 1995 to May 2009 were identified through an exhaustive literature search. The total number of articles was reduced to 32 articles, which were systematically coded and content analyzed. The findings indicated that the majority of studies focused on epidemiology, with relatively few of them focused on causal factors/etiology and systematic program development or evaluation. Gender differences in drug use were highlighted in several studies. Implications for culturally tailored interventions and future research are discussed.

A Systematic Review of Recent Literature on Religiosity and Substance Use

This paper contains a systematic review of articles about the relationship between religiosity/spirituality and alcohol and drug use that were published between 1997 and 2006. Summaries of methodological characteristics (e.g., study design, sample size and composition, specific dimensions of religiosity, and substances investigated) and general findings of 105 studies provide an overview of the field. The association between religiosity/spirituality and reduced risk of substance use is well established, but a well defined body of knowledge on this relationship has been slow to emerge. The development of more sophisticated instrumentation to measure religiosity and spirituality, the investigation of samples that include users of major drugs of abuse, and the integration of the study of religion and drug use into the broader literature on religion and health can help the field build upon the considerable work that has been published.
