ABSTRACT
Prior research suggests that culturally aligned, accessible and lower-barrier interventions are well-placed to align with the needs of American Indian and Alaska Native (AI/AN) people with alcohol use disorder (AUD). Taking into account community members' suggestions and the need for physical distancing during the COVID-19 pandemic, our team developed a protocol for virtual Harm Reduction Talking Circles (HaRTC) to incorporate these points. The aims of this 8-week, single-arm pilot were to initially document feasibility, acceptability, and outcomes associated with attendance at virtual HaRTC, which integrates the accessibility of virtual connection, a lower-barrier harm-reduction approach, and a culturally aligned intervention. Participants (N = 51) were AI/AN people with AUD (current or in remission) across 41 Tribal affiliations and 25 US states. After a baseline interview, participants were invited to attend 8, weekly virtual HaRTC sessions. At the baseline, midpoint and post-test assessments, we collected data on virtual HaRTC acceptability, cultural connectedness, quality of life, and alcohol outcomes. Of the 123 people approached, 63% were interested in and consented to participation. Participants attended an average of 2.1 (SD = 2.02) virtual HaRTC sessions, with 64% of participants attending at least one. On a scale from 1 to 10, participants rated the virtual HaRTC as highly acceptable (M = 9.3, SD = 1.9), effective (M = 8.4, SD = 2.9), culturally aligned (M = 9.2, SD = 1.5), helpful (M = 8.8, SD = 1.9), and conducted in a good way (M = 9.8, SD = 0.5). Although the single-arm study design precludes causal inferences, participants evinced statistically significant decreases in days of alcohol use and alcohol-related harm over the three timepoints. Additionally, both sense of spirituality, which is a factor of cultural connectedness, and health-related quality of life increased over time as a function of the number of HaRTC sessions attended. Virtual HaRTC shows initial feasibility and acceptability as a culturally aligned intervention for AI/AN people with AUD. Future randomized controlled trials will provide a test of the efficacy of this approach.

OBJECTIVE: Modified Mini-Mental State Examination (3MSE) is often used to screen for dementia, but little is known about psychometric validity in American Indians. METHODS: We recruited 818 American Indians aged 65-95 for 3MSE examinations in 2010-2013; 403 returned for a repeat examination in 2017-2019. Analyses included standard psychometrics inferences for interpretation, generalizability, and extrapolation: factor analysis; internal consistency-reliability; test-retest score stability; multiple indicator multiple cause structural equation models. RESULTS: This cohort was mean age 73, majority female, mean 12 years education, and majority bilingual. The 4-factor and 2nd-order models fit best, with subfactors for orientation and visuo-construction (OVC), language and executive functioning (LEF), psychomotor and working memory (PMWM), verbal and episodic memory (VEM). Factor structure was supported for both research and clinical interpretation, and factor loadings were moderate to high. Scores were generally consistent over mean 7 years. Younger participants performed better in overall scores, but not in individual factors. Males performed better on OVC and LEF, females better on PMWM. Those with more education performed better on LEF and worse on OVC; the converse was true for bilinguals. All differences were significant, but small. CONCLUSION: These findings support use of 3MSE for individual interpretation in clinic and research among American Indians, with moderate consistency, stability, reliability over time. Observed extrapolations across age, sex, education, and bilingual groups suggest some important contextual differences may exist.

Background/Objective: The goal of the Patient-Centered Outcomes Research Partnership was to prepare health care professionals and researchers to conduct patient-centered outcomes and comparative effectiveness research (CER). Substantial evidence gaps, heterogeneous health care systems, and decision-making challenges in the USA underscore the need for evidence-based strategies. Methods: We engaged five community-based health care organizations that serve diverse and underrepresented patient populations from Hawai'i to Minnesota. Each partner nominated two in-house scholars to participate in the 2-year program. The program focused on seven competencies pertinent to patient-centered outcomes and CER. It combined in-person and experiential learning with asynchronous, online education, and created adaptive, pragmatic learning opportunities and a Summer Institute. Metrics included the Clinical Research Appraisal Inventory (CRAI), a tool designed to assess research self-efficacy and clinical research skills across 10 domains. Results: We trained 31 scholars in 3 cohorts. Mean scores in nine domains of the CRAI improved; greater improvement was observed from the beginning to the midpoint than from the midpoint to conclusion of the program. Across all three cohorts, mean scores on 52 items (100%) increased (p ≤ 0.01), and 91% of scholars reported the program improved their skills moderately/significantly. Satisfaction with the program was high (91%). Conclusions: Investigators that conduct patient-centered outcomes and CER must know how to collaborate with regional health care systems to identify priorities; pose questions; design, conduct, and disseminate observational and experimental research; and transform knowledge into practical clinical applications. Training programs such as ours can facilitate such collaborations.
ABSTRACT
OBJECTIVE: People experiencing homelessness are disproportionately impacted by alcohol-related harm. Racially minoritized groups are disproportionately represented in the homeless population and are likewise disproportionately impacted by alcohol-related harm. Most alcohol outcome measures have not been adequately psychometrically studied in this marginalized population and across racial groups. This study documents psychometric properties, including measurement invariance, reliability, and convergent validity, of a measure of alcohol-related harm, the Short Inventory of Problems (SIP-2R), across Black, North American Indigenous (NAI), and White adults experiencing homelessness and alcohol use disorder (AUD). METHOD: Adults experiencing homelessness and AUD who had participated in one of two randomized controlled trials of harm-reduction treatment (N = 493; NAI = 205, Black = 125, and White = 163) were included in this psychometric study of the 15-item SIP-2R. RESULTS: Multigroup confirmatory factor analysis (MGCFA) indicated that a model comprising one general alcohol-related harm factor overarching five factors, showed close fit and partial scalar invariance, χ²(329, N = 493) = 624.902, p < .001, comparative fit index (CFI) = .966, root-mean-square error of approximation (RMSEA) = .074, 90% CI [.066, .083], standardized root-mean-square residual (SRMR) = .063, confirming acceptable measurement equivalence across racial groups. The SIP-2R showed internal consistency (α = .94, ω = .95) and convergent validity, that is, positive correlation between the total SIP-2R score and the number of drinks consumed the heaviest drinking day, ρ(490) = .30, p < .001. CONCLUSION: This study provided support for the internal consistency, convergent validity, and cross-group measurement equivalence of the SIP-2R for NAI, Black, and White adults experiencing homelessness with AUD.

Diet quality has been shown to be inversely associated with depression, but this has not been studied in American Indians (AIs). We examined the prospective association of diet quality and probable depression in a family-based cohort of rural AIs. Using data from the Strong Heart Family Study, we included 1,100 AIs ≥14 years old who were free of probable depression at baseline. We defined probable depression as the presence of moderate or severe depressive symptoms on the Center for Epidemiologic Studies Depression Scale or current use of antidepressant medications. We calculated baseline diet quality from food frequency questionnaires using the Alternative Healthy Eating Index-2010 (AHEI). We used GEE-based multivariate logistic regression to estimate the odds ratio of probable depression at follow up associated with a 10-point higher AHEI score at baseline, adjusted for demographic, psychosocial, and health factors. At follow up, 19% (n = 207) of the sample reported probable depression. Diet quality was not associated with report of probable depression at follow up (OR = 1.16, 95% CI [0.96, 1.39]). Research is needed to examine other temporal dimensions of this relationship and unique aspects of rural AI diets and psychosocial factors that may influence depression.

INTRODUCTION: There is tremendous need for efficacious and accessible interventions for smoking cessation among American Indians and Alaska Natives. We tested the efficacy of an Acceptance and Commitment Therapy (ACT)-based smartphone application (iCanQuit) versus US Clinical Practice Guidelines-based smartphone application (QuitGuide) for smoking cessation among American Indians and Alaska Natives. AIMS AND METHODS: We compared cessation, changes in ACT-based processes, engagement and satisfaction between American Indian and Alaska Native iCanQuit (n = 89) and QuitGuide (n = 80) participants enrolled in the iCanQuit trial. The primary outcome was self-reported, complete-case, 30-day point-prevalence abstinence. Follow-up timepoints were 12, 6, and 3 months. RESULTS: Randomized American Indians and Alaska Natives from 31 US states (70% urban, 30% rural, with 25% of participants residing on tribal land). The outcome data retention rates were 93%, 92%, and 90% at the 12-, 6-, and 3-month follow-ups, respectively, with no differential retention between arms. The 30-day point-prevalence abstinence for iCanQuit versus QuitGuide was 30% versus 18% at 12 months (odds ratio [OR] = 1.96; 95% confidence interval [CI]: 0.90 to 4.26) 25% versus 11% at 6 months (OR = 2.62; 95% CI: 1.06 to 6.45), and 15% versus 6% at 3 months (OR = 2.93; 95% CI: 0.90 to 9.59). Increases in acceptance of internal cues to smoke mediated the effect of treatment on smoking cessation at 12 months. iCanQuit arm participants were also significantly more engaged and satisfied with their assigned application. CONCLUSIONS: In a nationwide sample with high data retention and participant engagement, this is the first study to show that a digital intervention may be efficacious for helping American Indians and Alaska Natives quit smoking. IMPLICATIONS: This is the first study to provide evidence of an efficacious, accessible, and engaging treatment for helping American Indians and Alaska Natives quit smoking. Compared to a US Clinical Practice Guidelines-based smartphone application (QuitGuide), an ACT-based smartphone application (iCanQuit) was more efficacious, engaging, and satisfactory among American Indians and Alaska Natives nationwide. Our results will inform the tailoring of the iCanQuit smartphone application for American Indian and Alaska Native tribal communities and organizations with potential for broad dissemination and high impact.

The burden of Alzheimer's disease and related dementias (ADRD) has increased substantially in the United States, particularly in health disparity populations. Little is known about the epidemiology of ADRD in American Indian (AI) adults, although they have a high prevalence of ADRD risk factors including hypertension, diabetes, obesity, and smoking. Using electronic health records from a large health care organization during 2016-18, we describe characteristics of AI patients aged ≥55 years with and without an ADRD diagnosis, assess ADRD risk factors and contrast findings with results from age- and sex-matched non-Hispanic White (NHW) patients. To identify factors associated with ADRD diagnoses, we estimated population-averaged prevalence rate ratios to approximate relative risk (RR) using generalized estimating equations models adjusted for age, sex, and marital and rural residency status. The age-adjusted prevalence of ADRD diagnosis was 6.6% of AI patients, compared with 4.4% in NHW patients. Patient age and diagnosis of hypertension, depression, hyperlipidemia, or diabetes were significantly associated with higher risk of ADRD diagnosis in AIs (RR range: 1.1-2.8) whereas female sex or being married/having a partner were associated with lower risk of ADRD diagnosis (each RR=.7). ADRD risk factors were generally similar between AI and NHW patients, except for sex and marital status. However, the adjusted risk of ADRD was approximately 49% higher in AI patients. To our knowledge, our study is the first to examine ADRD diagnoses and comorbidities in AIs across a large geographical region in southwest United States. Future efforts to confirm our findings in diverse AI communities are warranted.

BACKGROUND: American Indians have excess risk of depression, which can contribute to cerebrovascular and cognitive disability, with effects on memory, processing speed, executive function, and visuospatial ability. However, studies examining depression and cognition in American Indians are limited; this study aims to report associations of depression with general cognition, verbal fluency and memory, and processing speed. DESIGN: Cohort study. SETTING: The Cerebrovascular Disease and its Consequences in American Indians study was an ancillary examination of Strong Heart Study participants from 3 U.S. regions. PARTICIPANTS: All eligible were included in this analysis (N=818). MEASUREMENTS: Participants completed evaluations for depressive symptomology, cognition, and physical function-including Center for Epidemiologic Studies Depression (CESD), Modified Mini-Mental State Examination (3MSE), Wechsler Adult Intelligence Scale-Fourth Edition coding (WAIS), Controlled Oral Word Association (COWA), California Verbal and Learning Test, Halstead finger tapping, grip strength, and Short Physical Performance Battery (SPPB) tests. Linear mixed models were adjusted for site, age, sex, education, income, marital status, alcohol, smoking, diabetes, hypertension, obesity, cholesterol, stroke, infarct, and hemorrhage. RESULTS: Symptoms of depression were common, with 20% (N=138) endorsing CES-D scores of 16+. More depressive symptoms were associated with older age, female sex, lower education, lower income, non-married status, not using alcohol, not smoking, hypertension, diabetes, and stroke. In adjusted analyses, processing speed (WAIS: ß -0.13, 95%CI -0.25, -0.03), general cognition (3MSE: ß -0.10, 95%CI -0.17, -0.03), verbal fluency (COWA: ß -0.10, 95%CI -0.19, -0.01), and motor function (SPPB: ß -0.05, 95%CI -0.07, -0.03) were significantly associated with more symptoms of depression. CONCLUSION: These findings maybe informative for health disparities populations, especially those with depressive risk. Clinicians may require particular training in cultural humility. Future studies should validate use of the CES-D scale in this population; longitudinal studies may focus on causal mechanisms and potential secondary prevention, such as social support.

OBJECTIVES: Insulin resistance is a substantial health issue for American Indians, with type 2 diabetes overrepresented in this population as compared with non-Hispanic whites. Insulin resistance and its related conditions in turn increase risk for dementia and cognitive impairment. The aim of the current study was to determine whether type 2 diabetes and insulin resistance at midlife was associated with later-life cognitive testing in a large sample of older American Indians, aged 65 and older. METHODS: American Indian participants who underwent both fasting blood draw as part of the Strong Heart Study and had subsequent cognitive testing as part of the later adjunct Cerebrovascular Disease and its Consequences in American Indians study were included (n = 790). Regression models examined type 2 diabetes and impaired fasting glucose and subsequent cognitive test performance as part of a longitudinal study design. The relationship between a continuous measure of insulin resistance and later cognitive test performance was assessed using generalized estimating equations. RESULTS: Controlling for demographic and clinical factors, verbal fluency and processing speed/working memory were significantly negatively associated with having type 2 diabetes and with insulin resistance, but not with impaired fasting glucose. CONCLUSION: In this sample of American Indians, type 2 diabetes at midlife was associated with subsequent lower performance on measures of executive function. These results may have important implications for future implementation of diagnostic and intervention services in this population.

Background: Smoking prevalence and mortality is 5 times higher for the chronically homeless versus general population. Unfortunately, traditional smoking cessation treatment does not optimally engage this population. In a preliminary study, smokers experiencing chronic homelessness suggested providers avoid giving advice to quit and instead use a more compassionate, nonjudgmental style to discuss a broader menu of patient-driven options, including safer nicotine use. Most had negative perceptions of smoking cessation medications; however, 76% expressed interest in a switchover to electronic nicotine delivery systems (ENDS). Methods: Using a community-based participatory research approach, we codeveloped harm-reduction treatment for smoking (HaRT-S) together with people with lived experience of chronic homelessness and smoking and a community-based agency that serves them. In HaRT-S, interventionists embody a compassionate, advocacy-oriented "heart-set" and deliver manualized components: a) participant-led tracking of smoking-related outcomes, b) elicitation of harm-reduction goals and progress made toward them, c) discussion of relative risks of nicotine delivery systems, and d) distribution and instructions on use of safer nicotine products. We then conducted a single-arm, 14-week pilot of HaRT-S (N = 44). Results: Participants rated procedures "totally acceptable/effective," which was reflected in 26% overrecruitment within a 4-month period and 70% retention at the 14-week follow-up. For each week in the study, participants experienced an 18% increase in odds of reporting 7-day, biochemically verified, point-prevalence abstinence. All participants reporting abstinence used ENDS. Participants evinced reductions in cigarette dependence (-45%), frequency (-29%), and intensity (-78%; ps < .05). Participants who used ENDS experienced an additional 44% reduction in smoking intensity and a 1.2-point reduction in dependence compared to participants who did not. Conclusions: Harm-reduction counseling plus ENDS shows promise for smokers experiencing chronic homelessness. Randomized controlled trials are needed to establish the efficacy of this approach in decreasing smoking-related harm and improving health-related quality of life for this marginalized and disproportionately affected population.

BACKGROUND: People experiencing homelessness are disproportionately affected by alcohol use disorder (AUD). Abstinence-based treatment, however, does not optimally engage or treat this population. Thus, harm reduction treatment for alcohol (HaRT-A) was developed together with people with lived experience of homelessness and AUD and community-based agencies that serve them. HaRT-A is a compassionate and pragmatic approach that aims to help people reduce alcohol-related harm and improve quality of life (QoL) without requiring abstinence or use reduction. A three-month, two-arm randomized controlled trial was conducted to test the initial efficacy of HaRT-A compared to a services-as-usual control condition. METHODS: People experiencing homelessness and AUD (N = 168; 24% women) were recruited in community-based clinical and social services settings. Self-reported alcohol use, alcohol-related harm, motivation, and QoL as well as urinary ethyl glucuronide were assessed over a 3-month follow-up. Participants were randomized to receive HaRT-A or services as usual. Over four sessions, HaRT-A interventionists delivered three components: a) collaborative tracking of participant-preferred alcohol metrics, b) elicitation of harm-reduction and QoL goals, and c) discussion of safer-drinking strategies. RESULTS: Compared to control participants, HaRT-A participants reported significantly greater increases in confidence to engage in harm reduction and decreases in peak alcohol use, alcohol-related harm, AUD symptoms, and positive urinary ethyl glucuronide tests (ps < .05). Findings were inconclusive regarding group differences on QoL (ps > .12). CONCLUSION: A low-barrier, low-intensity, patient-driven, harm-reduction approach has at least short-term efficacy in improving AUD outcomes in this population. Future studies are needed to establish its longer-term efficacy.

Community-based participatory research (CBPR) answers the call for more patient-centered, community-driven research approaches to address growing health disparities. CBPR is a collaborative research approach that equitably involves community members, researchers, and other stakeholders in the research process and recognizes the unique strengths that each bring. The aim of CBPR is to combine knowledge and action to create positive and lasting social change. With its origins in psychology, sociology, and critical pedagogy, CBPR has become a common research approach in the fields of public health, medicine, and nursing. Although it is well aligned with psychology's ethical principles and research aims, it has not been widely implemented in psychology research. The present article introduces CBPR to a general psychology audience while considering the unique aims of and challenges in conducting psychology research. In this article, we define CBPR principles, differentiate it from a more traditional psychology research approach, retrace its historical roots, provide concrete steps for its implementation, discuss its potential benefits, and explore practical and ethical challenges for its integration into psychology research. Finally, we provide a case study of CBPR in psychology to illustrate its key constructs and implementation. In sum, CBPR is a relevant, important, and promising research framework that may guide the implementation of more effective, culturally appropriate, socially just, and sustainable community-based psychology research.

BACKGROUND: Cigarette smoking is 5 times more prevalent among homeless individuals than in the general population, and homeless individuals are disproportionately affected by smoking-related morbidity and mortality. Homeless smokers report interest in changing their smoking behavior; however, established smoking cessation interventions are neither desirable to nor highly effective for most members of this population. The aim of this study was to document homeless smokers' perceptions of established smoking interventions as well as self-generated, alternative smoking interventions to elucidate points for intervention enhancement. METHODS: Participants (N=25) were homeless smokers who responded to semistructured interviews regarding smoking and nicotine use as well as experiences with established and alternative smoking interventions. Conventional content analysis was used to organize data and identify themes. RESULTS: Participants appreciated providers' initiation of conversations about smoking. They did not, however, feel simple advice to quit was a helpful approach. Instead, they suggested providers use a nonjudgmental, compassionate style, offer more support, and discuss a broader menu of options, including nonabstinence-based ways to reduce smoking-related harm and improve health-related quality of life. Most participants preferred engaging in their own self-defined, alternative smoking interventions, including obtaining nicotine more safely (e.g., vaping, using smokeless tobacco) and using behavioral (e.g., engaging in creative activities and hobbies) and cognitive strategies (e.g., reminding themselves about the positive aspects of not smoking and the negative consequences of smoking). Abrupt, unaided quit attempts were largely unsuccessful. CONCLUSIONS: The vast majority of participants with the lived experience of homelessness and smoking were uninterested in established smoking cessation approaches. They did, however, have creative ideas about alternative smoking interventions that providers may support to reduce smoking-related harm and enhance quality of life. These ideas included providing information about the relative risks of smoking and the relative benefits of alternative strategies to obtaining nicotine and avoiding smoking.

Engagement in religious and spiritual practices may be protective for homeless individuals with alcohol-related problems. However, little is known in this regard for urban-dwelling American Indians and Alaska Natives (AI/ANs) who have disproportionately high rates of homelessness and co-occurring alcohol use problems. Using secondary data from a nonrandomized controlled study testing a Housing First intervention, AI/AN participants (n = 52) and non-AI/AN participants (n = 82) were compared on demographic variables, alcohol use problems, religious affiliations, and religious/spiritual practices (importance, frequency, and type). AI/ANs who engaged in Native-specific independent spiritual practices had significantly lower alcohol use frequency in comparison to AI/ANs who did not.

BACKGROUND: Estimates of hippocampal volume by magnetic resonance imaging have clinical and cognitive correlations and can assist in early Alzheimer disease diagnosis. However, little is known about the relationship between global or regional brain volumes and cognitive test performance in American Indians. MATERIALS AND METHODS: American Indian participants (N=698; median age, 72 y) recruited for the Cerebrovascular Disease and its Consequences in American Indians study, an ancillary study of the Strong Heart Study cohort, were enrolled. Linear regression models assessed the relationship between magnetic resonance imaging brain volumes (total brain and hippocampi) and cognitive measures of verbal learning and recall, processing speed, verbal fluency, and global cognition. RESULTS: After controlling for demographic and clinical factors, all volumetric measurements were positively associated with processing speed. Total brain volume was also positively associated with verbal learning, but not with verbal recall. Conversely, left hippocampal volume was associated with both verbal learning and recall. The relationship between hippocampal volume and recall performance was more pronounced among those with lower scores on a global cognitive measure. Controlling for APOE ε4 did not substantively affect the associations. CONCLUSIONS: These results support further investigation into the relationship between structural Alzheimer disease biomarkers, cognition, genetics, and vascular risk factors in aging American Indians.

INTRODUCTION: Cell phones and personal computers have become popular mechanisms for delivering and monitoring health information and education, including the delivery of tobacco cessation education and support. Tobacco smoking is prevalent among American Indians (AIs) and Alaska Natives (ANs), with 26% AI/AN adult men smoking compared to 19% of Caucasian adult males and 22% of African American adult males. Smoking is even more prevalent in Northern Plains AI populations, with 42% of men and women reporting current smoking. The literature on the availability and use of cell phones and computers, or the acceptability of use in health promotion among AIs and ANs, is scant. The authors report findings from a survey of AI students regarding their cell phone and computer access and use. The survey was conducted to inform the development and implementation of a text messaging smoking cessation intervention modeled on a program developed and used in Australia. METHODS: A 22-item paper and pencil survey was administered to students at tribal colleges in rural Montana. The survey questions included cell phone ownership and access to service, use of cell phones and computers for health information, demographics, tobacco use habits, and interest in an intervention study. The study was reviewed and determined exempt by the institutional review boards at the tribal colleges and the lead research university. The study was conducted by researchers at the tribal colleges. Survey respondents received $10 when the survey was completed and returned. Data analysis was performed with the Statistical Package for the Social Sciences. RESULTS: Among 153 AI respondents, the mean age was 29 years, range was 18-64 years. Overall, 40% reported smoking cigarettes with a mean age of 16 years at initiation. A total of 131 participants (86%) had cell phones and, of those, 122 (93%) had unlimited text messaging. A total of 104 (68%) had smart phones (with internet access), although 40% of those with smart phones reported that internet access on their phone was very slow or location limited. A total of 146 (95%) participants reported having access to a computer, although 32% of those did not have daily access. Students aged less than 23 years were more likely to have cell phones with internet access. Cell phone ownership differed by site (93% vs 77%, p=0.007). About 60% of the respondents who smoked indicated interest in participating in the intervention study. CONCLUSIONS: This study revealed that AI tribal college students in the rural communities surveyed had less cell phone, smart phone, and computer and internet access than that reported for undergraduate college students elsewhere in the USA. Research efforts and public health interventions must be culturally appropriate and technologically viable, therefore access to and acceptability of mobile technology must be evaluated when planning and implementing interventions for rural and other marginalized populations. The findings from this study contribute to the literature regarding the access to and acceptability of mobile technology for health promotion among AI/AN college students in rural and remote areas, and helped introduce the proposed study to the community and solicited useful data regarding tobacco prevalence and interest in tobacco research in the target population.

BACKGROUND: American Indians and Alaska Natives have the highest obesity prevalence in the United States, but the influence of early childhood variables on body mass index (BMI; calculated as kg/m2) is not well understood. Previous studies have investigated the association between breastfeeding in infancy and offspring BMI, but rarely included American Indians and Alaska Natives. OBJECTIVE: This study investigated the association between breastfeeding in infancy and BMI in American Indians and Alaska Native and non-Hispanic white adolescents and young adults. DESIGN: Longitudinal analysis based on data from the National Longitudinal Study of Adolescent to Adult Health (1994 to 2008). PARTICIPANTS: Adolescent respondents who self-identified as American Indians and Alaska Native or non-Hispanic white, and whose parents completed the parental questionnaire, reported their height and weight. The final sample included 655 American Indians and Alaska Native and 10,305 non-Hispanic white respondents. STATISTICAL ANALYSES PERFORMED: Generalized estimating equations were used to measure the mean differences, 95% CIs, and P values of the association between breastfeeding in infancy and offspring BMI in adolescence, stratifying by race, and adjusting for demographic and socioeconomic variables. RESULTS: The length of breastfeeding was inversely associated with BMI in both populations. American Indians and Alaska Natives that were breastfed for 6 to 12 months or for more than 12 months had a mean BMI of 2.69 (95% CI -3.46 to -1.92; P<0.01) and 1.54 (95% CI -2.75 to -0.33; P<0.05) units lower than those that were never breastfed. Non-Hispanic whites that were breastfed for 3 to 6 months, 6 to 12 months, or more than 12 months had a mean BMI of 0.71 (95% CI -0.93 to -0.50; P<0.01), 0.68 (95% CI -0.87 to -0.50; P<0.01), and 0.85 (95% CI -1.09 to -0.62; P<0.01) units lower than those that were never breastfed. The association between the length of breastfeeding and offspring BMI varied by race (P<0.01). CONCLUSIONS: Breastfeeding in infancy is associated with lower mean BMI. Future research should investigate causal pathways and whether interventions promoting breastfeeding in American Indians and Alaska Natives can prevent increasing BMI.

The Cerebrovascular Disease and its Consequences in American Indians (CDCAI) Study recruited surviving members of a 20-year, longitudinal, population-based cohort of American Indians focused on cardiovascular disease, its risk factors, and its consequences. The goal of the CDCAI Study is to characterize the burden, risk factors, and manifestations of vascular brain injury identified on cranial MRI. The CDCAI Study investigators enrolled 1,033 participants aged 60 and older from 11 American Indian communities and tribes in the Northern Plains, Southern Plains, and Southwestern United States. In addition to cranial MRI performed according to standardized protocols, participants underwent extensive medical interview, clinical examination, neurocognitive testing, physical function evaluation, electrocardiogram, and provided blood and urine specimens. Participants also self-administered questionnaires covering demographics, quality of life, and medical history. This report describes the design, implementation, and some of the unique challenges of this study and data collection.

Social isolation, exposure to suicide, and overweight increase suicidal ideation in adolescents, but no study to date has examined their relative significance in American Indian and Alaska Native (AI/AN) youth. Generalized estimating equations and path analyses were used to measure the significance and mediation of these variables in the suicidal ideation of 721 AI/ANs and 12,107 White adolescents. Social isolation, exposure to suicide, and overweight were risk factors for suicidal ideation in both races, and the associations among the variables of interest and suicidal ideation varied by race. Interventionists need to consider race in the prevention of suicidal ideation in AI/AN and White youth.

Introduction The prevalence of pre-eclampsia, a major cause of maternal morbidity, varies by race, being greater in African Americans, and lower in Asians and Hispanics than in White women. Little is known about its prevalence in American Indians/Alaska Natives (AI/ANs). We estimated pre-eclampsia risk in AI/ANs compared to Whites, with consideration of the potential effect of obesity, a major risk factor for pre-eclampsia, and a condition disproportionately affecting AI/AN women. Methods This retrospective cohort study of linked birth-hospital discharge data from Washington State (2003-2013) included all AI/AN women and a sample of White first-time mothers with singleton deliveries. Logistic regression was used to estimate odds ratio (OR) and 95 % confidence intervals (CI) for pre-eclampsia risk in AI/ANs compared to Whites, first controlling for several important risk factors, and subsequently with additional adjustment for pre-pregnancy body mass index (BMI). Results AI/ANs had an increased risk of pre-eclampsia compared to Whites after controlling for all covariates except BMI (OR 1.17, 95 % CI 1.06-1.29). After further adjustment for BMI, the racial disparity in pre-eclampsia risk was greatly attenuated (OR 1.05, 95 % CI 0.95-1.16). Discussion This population-based study suggests that any increased risk in AI/ANs relative to Whites may be at least partly due to differences in BMI.
