Exploring Potential for a Personalized Medicine Approach to Smoking Cessation With an American Indian Tribe.

INTRODUCTION: A potential precision medicine approach to smoking cessation is tailoring pharmacotherapy to a biomarker known as the nicotine metabolite ratio (NMR). Little is known about the potential impact and acceptability of this approach for American Indian (AI) persons. AIMS AND METHODS: Tribal-academic collaboration was formed and during 2019-2020 AI adults who smoke(N = 54) were recruited to (1) examine correlations between NMR, dependence, and smoking exposure; (2) assess the extent to which pharmacotherapy preference aligned with NMR-informed recommendations; (3) explore acceptability of NMR-informed pharmacotherapy selection. Participants provided samples for assessment of salivary NMR and urinary total nicotine equivalents (TNE) and completed a questionnaire that assessed cigarettes per day (CPD), Fagerstrom Test for Cigarette Dependence (FTCD), pharmacotherapy preference, and perceptions of NMR-informed pharmacotherapy selection. RESULTS: Significant positive correlations were observed between NMR and FTCD (r = 0.29;p = .0383) and its abbreviated version Heaviness of Smoking Index (HIS) (r = 0.28;p =.0426). Post-hoc analyses suggest that relationships between dependence and NMR were driven by time to first cigarette. Nonsignificant, but directionally consistent, relationships were observed between NMR and CPD (r = 0.21; p =0.1436) and TNE (r = 0.24;p = .2906). Most participants preferred nicotine replacement therapy (71%) over varenicline (29%) and preference for pharmacotherapy matched NMR-based recommendations in 54% of participants. NMR-informed pharmacotherapy selection was supported by 62% of participants. CONCLUSION: In a sample of AI adults who smoke, NMR was related to cigarette dependence and about one-half of participants' pharmacotherapy preference matched their NMR-informed recommendation. There was lower acceptability of NMR-informed approach in this sample of AI adults than prior studies among white or black/African American people who smoke. IMPLICATIONS: Relationships between NMR, dependence, and self-preference for pharmacotherapy suggest that NMR-informed pharmacotherapy selection may have potential for enhancing smoking quitting success in this Tribe. Lower acceptability of NMR-informed pharmacotherapy in this Tribe suggests that this approach may not be equitably utilized. Future work could include identifying community-driven solutions to mitigate precision medicine concerns.

Turning Community Feedback into a Culturally Responsive Program for American Indian/Alaska Native Commercial Tobacco Users.

BACKGROUND: American Indian/Alaska Native (AI/AN) cigarette smoking prevalence is disproportionately high, especially in the northern United States. Tailored quitlines are needed to support AI/AN commercial tobacco users with quitting. OBJECTIVES: Obtain community feedback by working with trusted AI/AN partners; genuinely incorporate feedback into program design; collaboratively develop and implement culturally relevant quitline services for Minnesota's AI/AN community. METHODS: Working in partnership, AI/AN community input was gathered, and community partners were engaged to inform the development, training, implementation and monitoring of a tailored program within the existing state quitline. RESULTS: Findings suggest focusing on the commercial tobacco user/coach relationship, increased cultural understanding and program content adaptations could make quitlines more acceptable for AI/AN commercial tobacco users. CONCLUSIONS: The development and launch of the AI Quitline demonstrated the feasibility of collaboration among AI/AN organizations and community members, funders and providers to create a culturally relevant cessation service for AI/AN commercial tobacco users.

Tribal Tobacco Use Project II: Planning, Implementation, and Dissemination Using Culturally Relevant Data Collection among American Indian Communities.

American Indians have substantially higher commercial tobacco-related cancer rates when compared to the general population. To effectively combat commercial tobacco-related cancer, it is important that tribal nations obtain current and accurate community-specific data on commercial tobacco use and exposure-related attitudes and behaviors. With the goal to collect, synthesize, and disseminate data on tobacco use, including the role traditional tobacco plays among American Indian people, the American Indian Cancer Foundation (AICAF) and various stakeholders developed and implemented the Tribal Tobacco Use Project II (TTUP II) during 2018-2021. Building upon its predecessor, the Tribal Tobacco Use Project I (TTUP I), TTUP II used principles of community-based participatory research and culturally appropriate methods, such as Reality-Based Research, in partnership with tribal nations. We describe the TTUP II rationale, methods for participant recruitment and data collection, emphasizing the importance of using culturally relevant survey items to disentangle commercial tobacco use from traditional tobacco use. American Indian traditional tobacco is viewed as medicine in these communities with a unique socio-cultural context that must be addressed when engaging in commercial tobacco control efforts in American Indian communities. This approach may be useful to other tribal nations who are interested in conducting culturally relevant tobacco surveillance efforts.

Effects of culturally tailored smoking prevention and cessation messages on urban American Indian youth.

American Indians (AI) face significant disparities in smoking-related diseases. In addition, smoking prevalence increases exponentially between ages 11 and 18. Smoking prevention and cessation efforts aimed at AI youth therefore are important. In order to strengthen understanding of evidence-based message strategies for smoking prevention and cessation among AI youth. The objective of this study was to test whether a message that was tailored to AI cultural values associated with the sacredness of traditional tobacco can change variables that behavioral theories have identified as predictors of smoking (i.e., instrumental and experiential attitudes, injunctive and descriptive norms, perceived capacity and autonomy, and intention with respect to smoking). We conducted a randomized field experiment among 300 never-smoking and ever-smoking urban AI youth in Minneapolis-Saint Paul between May 18 and July 27, 2019. We used a 3 (message condition: cultural benefits of not smoking cigarettes, health benefits of not smoking cigarettes, comparison message about benefits of healthy eating) × 2 (smoking status: ever-smoked, never-smoked) between-subjects design. Multivariate analysis of variance showed that for ever-smokers, the cultural consequences of smoking message significantly lowered instrumental attitude (partial eta2 = 0.029), experiential attitude (partial eta2 = 0.041), perceived capacity (partial eta2 = 0.051), and smoking intention (partial eta2 = 0.035) compared to the healthy eating comparison message and the health consequences of smoking message. This was not observed among never-smokers, who already had very negative smoking perceptions. We conclude that messages that tailor to AI culture may be effective tools for discouraging smoking among AI youth.

Feasibility of a Systems Approach to Treat Commercial Tobacco Dependence within American Indian Health Clinics.

American Indians and Alaska Natives (AI/ANs) have the highest smoking prevalence, smoking-related disease, and mortality rates of any racial or ethnic group. Three AI health clinics in Minnesota implemented an evidence-based tobacco dependence treatment intervention that included provider education and customized clinical system tools. A baseline assessment of each clinic facility guided the focus of the intervention and tailored the clinical system tools. Clinic staff were assessed with pre/post-training evaluations and annual assessments. Results indicated self-reported improvements in the rate of identifying smoking status (57% to 89%), documenting smoking status (from 60% to 80%), and providing evidence-based treatments such as pharmacotherapy (from 36% to 78%).

Effects of cultural cues on perceptions of HPV vaccination messages among parents and guardians of American Indian youth.

The encouragement of human papillomavirus (HPV) vaccination is an important goal for interventions among American Indians (AIs), given the significant disparities AIs face with respect to HPV cancers. Tailoring intervention messages to the culture of message recipients has been proposed as a potentially useful intervention approach, yet cultural tailoring of HPV messages has never been tested among AIs. The objective of this research was to test the effectiveness of cultural tailoring in positively affecting two variables that have been proposed as mechanisms of tailoring effects, namely identification with the message and perceptions of message effectiveness. We conducted a between subjects randomized experiment among 300 parents of AI children. Participants saw one of three messages that differed in the extent to which the message contained cues to AI culture. Analysis of variance (anova) showed that participants identified more strongly (partial eta2 = 0.10) with messages that included stronger AI cultural features and thought these messages were more convincing (partial eta2 = 0.14) and pleasant (partial eta2 = 0.11) compared to messages that included weaker cultural cues. Effects on message identification and convincingness were moderated by AI identity, such that the more participants identified themselves with AI culture, the stronger the effects of the culturally-tailored messages were (R2change = 0.043 and 0.020 in hierarchical regression analyses). These findings suggest good potential for cultural tailoring to encourage HPV vaccination among AIs.

Influences and Practices in Colorectal Cancer Screening Among Health Care Providers Serving Northern Plains American Indians, 2011-2012.

INTRODUCTION: The epidemiology of colorectal cancer, including incidence, mortality, age of onset, stage of diagnosis, and screening, varies regionally among American Indians. The objective of the Improving Northern Plains American Indian Colorectal Cancer Screening study was to improve understanding of colorectal cancer screening among health care providers serving Northern Plains American Indians. METHODS: Data were collected, in person, from a sample of 145 health care providers at 27 health clinics across the Northern Plains from May 2011 through September 2012. Participants completed a 32-question, self-administered assessment designed to assess provider practices, screening perceptions, and knowledge. RESULTS: The proportion of providers who ordered or performed at least 1 colorectal cancer screening test for an asymptomatic, average-risk patient in the previous month was 95.9% (139 of 145). Of these 139 providers, 97.1% ordered colonoscopies, 12.9% ordered flexible sigmoidoscopies, 73.4% ordered 3-card, guaiac-based, fecal occult blood tests, and 21.6% ordered fecal immunochemical tests. Nearly two-thirds (64.7%) reported performing in-office guaiac-based fecal occult blood tests using digital rectal examination specimens. Providers who reported receiving a formal update on colorectal cancer screening during the previous 24 months were more likely to screen using digital rectal exam specimens than providers who had received a formal update on colorectal cancer screening more than 24 months prior (73.9% vs 56.9%, respectively, χ2 = 4.29, P = .04). CONCLUSION: Despite recommendations cautioning against the use of digital rectal examination specimens for colorectal cancer screening, the practice is common among providers serving Northern Plains American Indian populations. Accurate up-to-date, ongoing education for patients, the community, and health care providers is needed.

Cigarette Smoking Among Urban American Indian Adults - Hennepin and Ramsey Counties, Minnesota, 2011.

In 2013, it was estimated that the prevalence of cigarette smoking among American Indians was 36.5%, the highest of all racial/ethnic groups in the continental United States (1). Among American Indians, considerable cultural and geographic variation in cigarette smoking exists. Smoking prevalence among American Indians is lowest in the Southwest and highest in the Upper Midwest/Northern Plains (2). Little information is available about tobacco use among urban American Indians, who might not have ever lived on a reservation or be enrolled in or affiliated with a tribe. In Minnesota, a significant proportion of American Indians reside in urban areas. Among Minnesota's residents who identify as American Indian alone or in combination with another race, 30% live in Hennepin County and Ramsey County, which encompass Minneapolis and St. Paul, respectively (collectively known as the Twin Cities). The predominant tribes (Ojibwe [Chippewa] and Dakota/Lakota/Nakota [Sioux]) traditionally have used locally grown tobacco (Nicotiana rustica), red willow, and other plants for religious ceremonies, although nonceremonial tobacco is often substituted for traditional plants. To assess prevalence of cigarette smoking among this population, it is important to distinguish ceremonial tobacco use (smoked or used in other ways) from nonceremonial tobacco use. To obtain estimates of cigarette smoking prevalence among American Indians in Hennepin and Ramsey counties, the American Indian Adult Tobacco Survey was administered to 964 American Indian residents in 2011, using respondent-driven sampling. Among all participants, 59% were current smokers, 19% were former smokers, and 22% had never smoked. Approximately 40% of employed participants reported that someone smoked in their workplace area during the preceding week. High prevalences of cigarette smoking and secondhand smoke exposure among urban American Indians in Minnesota underscores the need for a comprehensive and culturally appropriate approach to reducing nonceremonial tobacco use.

Designing and evaluating culturally specific smoking cessation interventions for American Indian communities.

INTRODUCTION: American Indians have the highest smoking rates in the United States, yet few randomized controlled trials of culturally specific interventions exist. This study assessed American Indians' opinions about evidence-based treatment and attitudes toward participating in clinical trials. METHODS: Six focus groups were conducted based on smoking status (current/former smoker), sex, and elder status (55 years and older or younger). Meetings were held at local American Indian community organizations. This project was accomplished in partnership with the American Indian Community Tobacco Projects, a community-academic research partnership at the University of Minnesota. Thematic qualitative data analyses were conducted. RESULTS: Participants desired the following: (a) programs led by trained American Indian community members, (b) the opportunity to connect with other American Indian smokers interested in quitting, and (c) programs promoting healthy lifestyles. Strategies desired for treatment included (a) free pharmacotherapy, including nicotine replacement therapy (NRT); (b) nominal incentives, e.g., gift cards for groceries; and (c) culturally specific program components such as American Indian images, education on traditional tobacco use, and quit-smoking messages that target the value of family and include narratives or story telling in recruitment and program materials. Biochemical verification of smoking abstinence, such as salivary cotinine or carbon monoxide breathalyzers, is likely acceptable. Standard treatment or delayed treatment control groups were viewed as potentially acceptable for randomized study designs. CONCLUSIONS: Rigorously conducted randomized controlled trials of culturally specific smoking cessation interventions are sorely needed but will only be accomplished with the commitment of funders, researchers, and collaborative trusting relationships with the community.

Circles of Tobacco Wisdom: learning about traditional and commercial tobacco with Native elders.

BACKGROUND: Circles of Tobacco Wisdom (CTW) was an elder-led, community-based project that aimed to enhance tobacco control in the American Indian community. Its goal was to provide elders with the knowledge, opportunities, and support to enable them to assume leadership of a tobacco control movement that was grounded in the ceremonial traditions of tobacco use. PURPOSE: The purpose of this study was to test the effects of the pilot intervention on participants. DESIGN: The design of this pilot study intervention was a single group, pre-post comparison, with a pre-post survey, monthly check-ins, and a post-1-year focus group. PARTICIPANTS: Twelve elders were included in the pre- and post-analyses. All twelve elders were women who self-identified as American Indian (mean age = 64). INTERVENTION: The CTW elders participated in monthly talking circles, quarterly learning sessions, and a post-1-year focus group, and took part in other learning, support, and community action opportunities. Data were collected from December 2008 through November 2009 and analyzed throughout the process. MAIN OUTCOME MEASURES: American Indian Elders' tobacco-related knowledge, perceptions, beliefs, and behaviors were measured while participating in the CTW project. RESULTS: Knowledge, perceptions, beliefs, and behavior changes were seen with cigarette smoking, secondhand smoke, and ceremonial tobacco use and risk perception. After 6 months, the number of people the elders had talked with about tobacco increased, elders were more likely to have a discussion on tobacco at a community event, and their comfort level talking about commercial and traditional tobacco also increased. A number of themes also were identified in the focus group: feeling more comfortable talking about tobacco issues, learning a lot about traditional and commercial tobacco, and realizing the dangers of smoking. CONCLUSIONS: Elders increased their knowledge about commercial and traditional tobacco and changed related attitudes as a result of CTW. Further, American Indian Elders perceived that CTW was effective.

Cigarette smoking among American Indian youth in Minneapolis-St. Paul.

BACKGROUND: Reported prevalence of cigarette smoking among American Indian youth is higher than other racial/ethnic minorities, and limited data indicate that this disparity is especially pronounced in the Upper Midwest of the U.S. The purposes of this study are to measure traditional and recreational tobacco use among American Indian youth in an urban Upper Midwest area, and to identify social and environmental factors associated with recreational tobacco use (cigarette smoking). METHODS: A cross-sectional convenience sample of 336 American Indian youth aged 11-18 years was given a self-administered survey. Data were analyzed using bivariate chi-square tests and multivariate logistical stepwise regression. RESULTS: Almost 37% reported some recreational smoking in the previous 30 days, with about three times as many in the group aged 16-18 years reporting smoking as in the group aged 11-13 years (p<0.0001). Social exposure to cigarette smoking was very strong; more than three fourths reported living with an adult who smokes, and 44% have a brother/a sister who smokes. Yet more than 65% report a household rule against their smoking, and 43% report a household rule against anyone smoking inside. Youth who smoke report buying cigarettes often and smoking on school property. Household rules against smoking and hearing of someone getting caught smoking at school have an independent negative association with likelihood of being a smoker. CONCLUSIONS: These results indicate that American Indian youth in this area report high use of recreational tobacco, and the statewide focus on youth smoking prevention has not eliminated the disparity in smoking levels between American Indian youth and Minnesota youth overall. These findings suggest several pathways to reduce cigarette smoking among urban American Indian youth.

American Indian breastfeeding attitudes and practices in Minnesota.

OBJECTIVES: We examined the breastfeeding attitudes and practices in an American Indian population in Minnesota. METHODS: We interviewed women prenatally (n = 380), at 2-weeks (n = 342) and at 6-months postpartum (n = 256). We conducted multivariable analyses to examine the demographic, behavioral, and attitudinal correlates of breastfeeding initiation and duration. RESULTS: Factors positively associated with breastfeeding initiation included positive breastfeeding attitudes and social support for breastfeeding from the woman's husband/boyfriend and her mother. Factors positively associated with breastfeeding at 2-weeks postpartum were support from the woman's mother and positive attitudes about breastfeeding. The prenatal use of traditional American Indian medicines and cigarette smoking were both significantly associated with breastfeeding at 6-months postpartum. CONCLUSIONS: Programs to encourage breastfeeding in American Indian communities may be strengthened with protocols to encourage social support, recognition of the perceived health, developmental, and practical benefits of breastfeeding, and a focus on traditional American Indian health practices.

Native Teen Voices: adolescent pregnancy prevention recommendations.

PURPOSE: American Indian adolescent pregnancy rates are high, yet little is known about how Native youth view primary pregnancy prevention. The aim was to identify pregnancy prevention strategies from the perspectives of both male and female urban Native youth to inform program development. METHODS: Native Teen Voices (NTV) was a community-based participatory action research study in Minneapolis and St. Paul, Minnesota. Twenty focus groups were held with 148 Native youth who had never been involved in a pregnancy. Groups were stratified by age (13-15 and 16-18 years) and sex. Participants were asked what they would do to prevent adolescent pregnancy if they were in charge of programs for Native youth. Content analyses were used to identify and categorize the range and types of participants' recommendations within and across the age and sex cohorts. RESULTS: Participants in all cohorts emphasized the following themes: show the consequences of adolescent pregnancy; enhance and develop more pregnancy prevention programs for Native youth in schools and community-based organizations; improve access to contraceptives; discuss teen pregnancy with Native youth; and use key messages and media to reach Native youth. CONCLUSIONS: Native youth perceived limited access to comprehensive pregnancy prevention education, community-based programs and contraceptives. They suggested a variety of venues and mechanisms to address gaps in sexual health services and emphasized enhancing school-based resources and involving knowledgeable Native peers and elders in school and community-based adolescent pregnancy prevention initiatives. A few recommendations varied by age and sex, consistent with differences in cognitive and emotional development.

Patterns of tobacco use in a sample of American Indians in Minneapolis-St. Paul.

The purpose of this study was to identify patterns of tobacco initiation, current use, and smoking cessation and their correlates in the adult American Indian population in the Twin Cities, using community-based participatory research methods. A total of 300 American Indians aged 18 years or older participated in in-person interviews. Participants were recruited to fill age-gender quotas that reflect the demographic distribution of American Indians in Minnesota. Almost everyone in this sample had smoked cigarettes recreationally: Only 12% had smoked fewer than 100 cigarettes, and nearly two-thirds (62%) reported that they were current smokers. Only 29% of ever-smokers had quit smoking. More than two-thirds (68%) of current smokers would like to quit, and most of them (53% of all smokers) had tried unsuccessfully to quit in the previous 12 months. Our results show a level of current smoking and low cessation rates among American Indians in the Twin Cities area that reflect a crisis for public health and for the Indian community.

Early otitis media among Minnesota American Indians: the Little Ears Study.

OBJECTIVES: We examined relationships between otitis media risk factors, sociodemographic characteristics, and maternal knowledge and attitudes and early onset of otitis media. METHODS: Pregnant women from Minnesota American Indian reservations and an urban clinic were enrolled in our study between 1998 and 2001. Follow-up was performed on enrollees' infants until the children were 2 years old. Research nurses collected data by ear examination, from interviews and questionnaires given to enrolled mothers, and otitis media episodes that were abstracted from medical records. RESULTS: Sixty-three percent of infants had experienced an otitis media episode by 6 months of age. Logistic regression analyses showed that maternal otitis media history, infant history of upper respiratory infection, and compliance with study visits were significantly related to early otitis media onset. Although high percentages of infants were exposed to cigarette smoke and other children and were formula fed, these factors were not related to otitis media. Mothers' prenatal awareness of otitis media risks associated with environmental tobacco smoke exposure and formula feeding did not predict their postpartum behaviors. CONCLUSIONS: We found that infant history of upper respiratory infection and maternal otitis media history are risk factors for early otitis media in American Indian infants. Mothers' prepartum knowledge and attitudes regarding otitis media did not predict their postpartum avoidance of risk behaviors.

Environmental, social, and personal correlates of having ever had sexual intercourse among American Indian youths.

OBJECTIVES: We examined the correlates of having ever had sexual intercourse among American Indians aged 13 to 18 years in Minnesota. METHODS: To assess key environmental, social, and individual correlates of sexual experience, we analyzed data from 4135 American Indian youths who participated in the 1998 and 2001 Minnesota Student Surveys. RESULTS: Forty-two percent of those aged 13 to 15 years and 69% of those aged 16 to 18 years reported that they had ever had sexual intercourse. Correlates of sexual experience varied by age and gender. School connections had the strongest negative associations with sexual experience in young girls, and living with a father had negative associations with sexual experience for younger, but not older, youths. Sexual experience was most strongly and positively associated with risk behaviors such as substance use, violence exposure, and violence perpetuation. CONCLUSIONS: The strongest correlates of sexual experience for American Indian youths were high-risk behaviors and exposure to violence. Future work is needed to develop and employ measures that reflect youth assets and that specifically reflect the experiences of American Indian youths.
