Adolescent Tobacco and Betel Nut Use in the US-Affiliated Pacific Islands: Evidence From Guam

Resistance to peer influence, smoking friends, cigarette and betel nut use, and gender among Pacific Islander youth

The present study examined the relationships between resistance to peer influence and cigarette and betel nut use, as well as the potential mediating role of friends who use cigarettes and betel nut, among boys and girls in Guam. This study included 673 ethnically diverse students (49% female; M age = 12.7, SD = 0.89) from eight public middle schools. The mediation analysis demonstrated that higher resistance to peer influence for both cigarette and betel nut use was associated with lower cigarette and betel nut use directly and that this association was mediated by friends who used cigarette and betel nut products. That is, low resistance to peer influence for both cigarette and betel nut use was associated with a greater number of friends who smoke and use betel nut, which was linked with more cigarette and betel nut use. The moderated mediation analysis revealed no gender difference in the indirect effect (i.e., the mediation of friends who used cigarettes and betel nut). These findings can be used to inform the design and implementation of intervention and prevention programs for at-risk youth, regardless of gender, who are vulnerable to substance use in the Pacific.

Types of Offers of Combustible Cigarettes, E-Cigarettes, and Betel Nut Experienced by Guam Youths

The present study examined types of scenarios in which Guam youths are offered tobacco-namely, combustible cigarettes and e-cigarettes-and betel (areca) nut. We conducted 10 focus groups with public middle school students (n = 34) from Guam. Results suggested that the types of offer scenarios of combustible cigarettes, e-cigarettes, and betel nut referenced by the students fall into two categories-direct-relational offers and indirect-contextual offers. The results also suggested that both categories of offer scenarios were more likely to occur in school rather than in other locations such as the home. Family members were more likely to make offers than other types of people. Indirect-contextual offers were more easily avoidable depending on the substance offered, the location where the offer took place, and the person making the offer. Based on the findings, we provide brief suggestions on developing a school-based prevention curriculum focused on training young adolescents from Guam on ways to resist offers of cigarettes, e-cigarettes, and betel nut.

A Mediation Model for Biculturalism and Cigarette and Betel Nut Use: The Case of Adolescents in Guam

The present study examined the associations between biculturalism and cigarette and betel nut use and the potential mediating roles of cigarette and betel nut use risk perception and resistance to peer and adult influence among adolescents in Guam. Participants were 673 ethnically diverse students (49% female; Mage = 12.7, SD = .89) from eight public middle schools. The results showed that biculturalism was not associated with cigarette use directly; however, this association was mediated by cigarette use risk perception and resistance to peer and adult influence. In other words, higher biculturalism was associated with more risk perception and then more resistance to peer and adult influence, which sequentially predicted less cigarette use. Similarly, the association between biculturalism and betel nut use was mediated by betel nut use risk perception and resistance to peer and adult influence. Higher biculturalism was associated with greater risk perception and then more resistance to peer and adult influence, which in turn resulted in less betel nut use. These findings can be used to inform the design and implementation of intervention and prevention programs targeting youth who are vulnerable to substance use.

Guam Adolescents' Use of Strategies to Resist Cigarette, e-Cigarette, and Betel Nut Offers: Findings from a Focus Group Study

Background: This study examined resistance strategies used by predominantly Pacific Islander young adolescents in response to offers of tobacco, e-cigarettes, and betel [areca] nuts. This study was intended to inform the development of a prevention curriculum focused on training young adolescents from the U.S.-Affiliated Pacific Islands (USAPI) on culturally appropriate strategies to resist substance use offers. Currently, very little is understood in terms of how Pacific Islander youths deal with tobacco and other substance use offers, although the use of tobacco products among Pacific Islander youths is high. Specifically, given the collectivist sociocultural orientation of the Pacific Islander communities, it is unclear whether the direct (overt) confrontational style of resistance is a viable mode of resistance for youths to practice when faced with a substance use offer. Methods: We conducted 10 focus groups with public middle school students (N = 34) from Guam, which is part of the USAPI. Results: Results suggested that, as with other communities in the U.S., the resistance strategies fall into two categories-overt/confrontational and non-confrontational resistance strategies. Overt/confrontational strategies included (a) saying "no" and (b) verbally confronting the offeror. Non-confrontational strategies included (a) avoiding or leaving the situation and (b) telling an adult. Conclusions: Our findings have implications for the development of culturally grounded interventions aimed at preventing youth tobacco and other substance use in Guam, the USAPI, and the Pacific region.

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.

Tobacco product use and cultural connectedness among Native Hawaiian/Pacific Islander, Asian American, and Filipino American young adults in Hawai'i

Tobacco product use rates among Native Hawaiian/Pacific Islander (NHPI), Asian American, and Filipino American young adults in Hawai'i have risen rapidly in recent years following the introduction of electronic nicotine delivery systems. Though some research has examined tobacco use correlates for these demographics of young adults, research examining protective factors, such as cultural connectedness, is lacking. Additionally, research that disaggregates Asian Americans from Pacific Islanders is scarce, despite the differing risk and protective factors that have been determined for each group. This study separately examined cultural connectedness among NHPIs, Asian Americans, and Filipino Americans to help fill the gaps in the current tobacco product literature. The findings indicated that Asian Americans and Filipino Americans who identify more with their own cultures are less likely to use e-cigarettes; however, this relationship was not supported for NHPIs. No significant evidence was found to indicate a relationship between cultural connectedness and combustible cigarette use among any of the sampled groups. The lack of relationship between cultural connectedness and e-cigarette use among Native Hawaiians may be explained by measurement limitations in the study, and suggest the need for more culturally competent scales (e.g., an enculturation scale) that account for Indigenous status.

Social media, peer norms, and betel nut susceptibility and use: Evidence from early adolescents in Guam

Betel (areca) nut is an addictive psychoactive substance considered to be carcinogenic. Yet not much is known about factors that may be promoting betel nut use. To fill this void, the present study examines the roles of exposure to betel nut-related posts on social media and peer norms regarding betel nut use in explaining betel nut susceptibility and use among adolescents. We conducted a representative survey of early adolescents (N = 673) attending all public middle schools on Guam, a United States-Affiliated Pacific Island in the Western Pacific. Results showed that exposure to betel nut-related posts on social media was positively associated with peer descriptive norms regarding betel nut use. Specifically, the more frequent early adolescents were exposed to betel nut posts on social media, the more likely they were to perceive betel nut use to be more prevalent among their general peers and close friends. Additionally, early adolescents' exposure to betel nut-related posts on social media was positively associated with both their susceptibility to use betel nut and reported use. Descriptive norms regarding close friends' betel nut use was also positively associated with both susceptibility to and use of betel nut. However, descriptive norms regarding general peers' betel nut use was unrelated with either betel nut susceptibility or use. Descriptive norms regarding close friends' betel nut use mediated the relationships that exposure to betel nut posts on social media had with both betel nut susceptibility and betel nut use. Implications are discussed.

Exposure to tobacco and betel nut content on social media, risk perceptions, and susceptibility to peer influence among early adolescents in Guam

Introduction

This study aimed to examine the associations between exposure to tobacco and betel nut-related content on social media, perceived risks of tobacco and betel nut use, and susceptibility to peer influence for tobacco and betel nut use among adolescents living in Guam, a United States-Affiliated Pacific Island in the Western Pacific.

Methods

A representative survey of adolescents (N = 670) attending public middle schools on Guam was conducted. The survey measured exposure to tobacco and betel nut content on the following social media platforms: (a) Facebook, (b) Twitter, (c) Instagram, (d) Snapchat, and (e) WhatsApp. The survey also measured perceived risks of tobacco and betel nut use and susceptibility to peer influence for tobacco and betel nut use.

Results

Guam adolescents' exposure to tobacco-related content on social media was found to be associated with lower perceived risks toward the use of tobacco (β = -0.18, p < 0.001) and betel nut (β = -0.16, p < 0.001). Also, exposure to tobacco-related content on social media was found to be associated with higher levels of susceptibility to peer influence for uses of both tobacco (β = 0.10, p < 0.05) and betel nut (β = 0.15, p < 0.001). Similarly, exposure to betel nut-related content on social media was associated with lower perceived risks of using betel nut (β = -0.20, p < 0.001) and tobacco (β = -0.24, p < 0.001). Also, exposure to betel nut-related content on social media was associated with increased susceptibility to peer influence for use of both betel nut (β = 0.35, p < 0.001) and tobacco (β = 0.29, p < 0.001).

Conclusions

Adolescents' exposure to tobacco- and betel nut-related content on social media may influence attitudinal risk factors associated with tobacco and betel nut use.

Evidence of areca nut consumption in the United States mainland: a cross-sectional study

BACKGROUND

Areca nut (AN) is an addictive substance consumed in the Southeast region and is highly associated with oral premalignant lesions and oral cancer. The impact of AN use in the United States (US) is largely unknown, but the products are readily available and probably used by a significant fraction of Asian immigrants or descendants living in the US. We aimed at assessing AN use prevalence among the Asian community in Houston, Texas.

METHODS

A cross-sectional questionnaire was used to interview adult individuals (≥ 18 years of age) who self-identified as Asian immigrants or descendants residing in Houston. Means, frequencies, and proportions were reported. Factors associated with AN use were evaluated using logistic regression.

RESULTS

We surveyed 275 individuals (58% women, 43% between 35-54 years old, 67% born outside of the US, and 6% concurrent smokers). Among respondents, 91% were familiar with AN products, 17% self-reported ever use of AN products in the US, and 31% had friends/family members who were AN ever users. AN use was significantly associated with being Indian Subcontinent immigrants or descendants (ISID) (OR = 3·9; CI: 1·10,13·81; p = 0·035) and having friends/family members using AN products (OR = 6·2; CI: 1·69, 22·69; p = 0·006).

CONCLUSIONS

Our findings provide quantitative data on the prevalence of AN ever use and context for future AN prevention and cessation interventions specific to the Southeast Asian groups living in the US mainland. This is crucial for the prevention and control of oral cancer and other detrimental conditions related to AN consumption.

Prevalence of E-Cigarette Use and Its Associated Factors Among Youths Aged 12 to 16 Years in 68 Countries and Territories: Global Youth Tobacco Survey, 2012‒2019

Objectives. To describe the recent global prevalence of e-cigarette use and to investigate its associated factors among youths aged 12 to 16 years in 68 countries and territories (hereafter "countries"). Methods. We analyzed 485 746 youths aged 12 to 16 years from the population-based cross-sectional Global Youth Tobacco Survey conducted in 67 countries between 2012 and 2019 and the 2019 National Youth Tobacco Survey in the United States. We defined past-30-day e-cigarette use as using e-cigarettes on 1 or more days during the past 30 days. Results. The global prevalence of past-30-day e-cigarette use among youths was 9.2%, ranging from 1.9% in Kazakhstan to 33.2% in Guam. Maternal smoking (adjusted odds ratio [AOR] = 1.40; 95% confidence interval [CI] = 1.29, 1.52), paternal smoking (AOR = 1.13; 95% CI = 1.07, 1.19), secondhand smoke exposure (AOR = 1.74; 95% CI = 1.64, 1.84), youth cigarette smoking (AOR = 7.18; 95% CI = 6.84, 7.54), and youth other tobacco use (AOR = 3.88; 95% CI = 3.62, 4.15) were positively associated with e-cigarette use. Conclusions. E-cigarette use was moderately frequent among youths aged 12 to 16 years globally. Several important factors were associated with youth e-cigarette use. Public Health Implications. Our findings highlight the need for countries worldwide to develop policies to address e-cigarette use among youths.

Development and evaluation of an undergraduate curriculum on non-communicable disease research in Guam: The Pacific Islands Cohort of College Students (PICCS)

BACKGROUND

The non-communicable disease (NCD) epidemic among Pacific Islanders prompted the declaration of a regional state of NCD emergency throughout the United States-Affiliated Pacific Islands (USAPIs) in 2010. Subsequently, the University of Guam Health Science Program launched a pilot study on NCD research in its undergraduate curriculum modeled after the Pacific Data for Decision Making (DDM) framework - a field epidemiology training program employed in the USAPIs. The primary objective of the research is to conduct annual assessments of student health indicators with plans for longitudinal follow-up. Here, development and evaluation of the undergraduate research curriculum are described.

METHODS

The Pacific DDM framework covering knowledge and skills in resourcing, types of data and indicators, data sources, data management, information products, and data dissemination and use were incorporated in undergraduate core courses of the Health Science Program. During the data collection pilot years, 2013 and 2014, a survey containing questions predominantly on NCD risk factors was launched at the university. The survey was administered by upperclassmen in the Health Science Program and evolved into the Pacific Islands Cohort of College Students (PICCS) research study. The initial years were spent developing the infrastructure. Program outputs were tracked annually to measure program success.

RESULTS

Students in the Health Science Program obtained research knowledge and skills through various courses while enrolled in the program. The PICCS data collection continued annually as a cross-sectional survey from 2015 to current. Numerous successes have resulted including student abstracts and publications, acceptances to summer programs and fellowships, a sustained annual health fair for college students, a grant award, and other program-related impacts.

CONCLUSION

The PICCS framework provided the organizational structure and documented tools, protocols, roles, and responsibilities to enhance consistency and reproducibility. Undergraduate students applied their knowledge and skills to an ongoing study focused on NCD risk factor surveillance of college students. Additionally, multiple research successes have been achieved through the PICCS curriculum. Plans are underway to begin the longitudinal design of the PICCS research study and sustain it through the curriculum, with room for adaptation as courses are updated over time.

'Hybrid Survey' approach to non-communicable disease surveillance in the US-Affiliated Pacific Islands

In 2010 the US-Affiliated Pacific Islands (USAPI) declared a regional state of health emergency due to the epidemic of non-communicable disease (NCD) and an NCD monitoring and surveillance framework was developed that includes adult NCD risk factor and disease prevalence indicators to be collected every 5 years using a population-based survey. On evaluation of existing data from adult population-based NCD surveys, it was found that there was a lack of valid, available and consistently collected data. Therefore, a new model was developed to combine various indicators and survey tools from different partner agencies into one survey. After the report was endorsed by local health leadership, a dissemination workshop was conducted. In 2015 (baseline for Hybrid Survey implementation), three out of nine jurisdictions (33.3%) had completed a population-based survey in the past 5 years. Four (44.4%) had no adult prevalence data at all, two (22.2%) had data sets from their surveys and four (44.4%) had at least two surveys ever collected that could be used for comparison. As of 2020, all nine jurisdictions have, or are in the process of completing an adult population-based survey. Eight (88.9%) have data sets from their surveys, and five (55.6%) have at least two surveys collected that can be used for comparison. This Hybrid Survey model has helped to improve adult NCD surveillance in the USAPI by more efficiently using limited resources. This model could be considered in other small island nations, or rural areas where adult NCD surveillance is challenging.

An Instagram-Based Study to Understand Betel Nut Use Culture in Micronesia: Exploratory Content Analysis

BACKGROUND

A 2012 World Health Organization report recognizes betel nut use as an urgent public health threat faced by the Western Pacific region. However, compared with other addictive substances, little is known about how betel nuts are depicted on social media platforms. In particular, image-based social media platforms can be powerful tools for health communication. Studying the content of substance use on visual social media may provide valuable insights into public health interventions.

OBJECTIVE

This study aimed to explore and document the ways that betel nut is portrayed on the photo-sharing site Instagram. The analysis focuses on the hashtag #pugua, which refers to the local term for betel nut in Guam and other parts of Micronesia.

METHODS

An exploratory content analysis of 242 Instagram posts tagged #pugua was conducted based on previous research on substance use and Instagram and betel nut practices in Micronesia. In addition, the study examined the social engagement of betel nut content on the image-based platform.

RESULTS

The study findings revealed content themes referencing the betel nut or betel nut tree, betel nut preparation practices, and the unique social and cultural context surrounding betel nut activity in Guam and Micronesia. In addition, certain practices and cultural themes encouraged social engagement on Instagram.

CONCLUSIONS

The findings from this study emphasize the cultural relevance of betel nut use in Micronesia. These findings provide a basis for empirically testing hypotheses related to the etiological roles of cultural identity and pride in shaping betel nut use behavior among Micronesians, particularly youths and young adults. Such research is likely to inform the development of culturally relevant betel nut prevention and cessation programs.

Investigating Betel Nut Use, Antecedents and Consequences: A Review of Literature

Background: Betel nut use is a public health issue in the Asia-Pacific region that is often neglected. To control betel nut use, understanding of the adverse effects of betel nut use and evidence-based policies and strategies is necessary. Objectives: This narrative review aims to characterize the current situation on betel nut use at a global level regarding the epidemiology, pharmacology and toxicology, health effects, treatment options, policies and strategies. Methods: We found 139 existing literature published between 1970-2019 on the Web of Science database and other technical documents to collate the most relevant information on betel nut use. Data were categorized into appropriate themes. Results: The literature demonstrates that there is a lack of up to date statistics on betel nut use. There is limited research on the effect of policies and strategies to control betel nut use. Conclusion: Betel nut-chewing countries should focus on understanding which populations chew betel nut and implement appropriate policies, educational and cessation programs to help control betel nut use.
