Testing a Culturally Tailored Advance Care Planning Intervention (MY WAY) for an American Indian Tribe: Protocol for a Quasi-Experimental Waitlist Control Design.

BACKGROUND: American Indian and Alaska Native peoples experience poor end-of-life care, including more hospitalizations and lower use of hospice and do-not-resuscitate orders. Although advance care planning (ACP) can improve end-of-life care, ACP rates are disproportionately low in American Indians and Alaska Natives. OBJECTIVE: We culturally tailored and delivered an existing evidence-based ACP program for an American Indian tribal community. Here, we present the protocol for assessing the intervention's feasibility and efficacy. METHODS: We measured feasibility via participant recruitment, participants' evaluation (acceptability, appropriateness, comprehension, and satisfaction), and intervention fidelity. Recruitment was measured with participant screening, eligibility, enrollment, and retention. Participant's evaluation of the intervention was measured with surveys. Fidelity was measured with direct observation and the Make Your Wishes About You (MY WAY) Fidelity Checklist Tool. To assess the intervention's efficacy, we used a quasi-experimental waitlist control design with 2 cohorts who were surveyed each on three separate occasions. The intervention's efficacy was assessed by the following: ACP barriers and facilitators as well as ACP self-efficacy, readiness, and completion. RESULTS: A total of 166 participants were screened for eligibility; 11 were deemed ineligible, and 155 participants were enrolled in the study. Of those enrolled, 113 completed the intervention and will be included in subsequent analyses. We finalized data collection in January 2023, and analyses are underway. Study enrollment was successful, and we expect that participants will report high levels of acceptability, appropriateness, comprehension, and satisfaction with the intervention. We expect that the intervention was implemented with fidelity and will demonstrate decreases in ACP barriers and increases in ACP facilitators, self-efficacy, readiness, and completion. CONCLUSIONS: Enrolling over twice as many participants as we had hoped suggests that members of this tribal community are willing to engage in end-of-life ACP. We were able to implement a waitlist study design to show that a culturally tailored ACP program for a tribal community is feasible.

Experiences With and Access to Evidence-Based Health Promotion Programs for Older American Indian, Alaska Native, and Native Hawaiian Peoples.

Evidence-based programs (EBPs) work effectively for participants whose characteristics match those of the EBP research participants. However, EBPs have been almost exclusively developed and evaluated for the general U.S. population with limited American Indian, Alaska Native, and Native Hawaiian (AI/AN/NH) community engagement. Thus, an AI/AN/NH Evidence-Based Program Advisory Council sought to identify AI/AN/NH peoples' experiences with and access to EBPs. We held 20 listening sessions with AI/AN/NH Elder services program staff (n = 118) and with AI/AN/NH Elders (n = 82) and conducted a self-administered online survey with Title VI Directors (n = 63). The six themes that emerged from the listening sessions with staff included misunderstanding community engagement, valuing fidelity over flexibility, lack of cultural awareness, assumptions about available infrastructure, unrealistic implementation timelines, and funding restrictions. Listening session themes with Elders included definitions of aging well, participation motivators, preferred activities, participation barriers, and unmet needs. Survey data indicated that programming of greatest interest for Elders as identified by Title VI Directors and staff included and/or addressed cultural activities (81%), socialization (75%), diabetes (73%), caregiving (68%), and nutrition (68%). Seventy-six percent of survey respondents had heard of EBPs and 24% indicated that EBPs were not being implemented in their community. The Advisory Council developed specific action steps with the goal of improving AI/AN/NH communities' access to culturally appropriate and feasible EBPs. The steps require collective action from federal agencies, national partners, EBP program developers and administrators, local organizations, and Elders to ensure EBPs are accessible and culturally appropriate for AI/AN/NH Elders.

Association of Medication Adherence With HbA1c Control Among American Indian Adults With Type 2 Diabetes Using Tribal Health Services.

OBJECTIVE: To examine HbA1c levels and adherence to oral glucose-lowering medications and their association with future HbA1c levels among American Indian adults with type 2 diabetes (T2D) receiving medications at no cost from a tribal health care system. RESEARCH DESIGN AND METHODS: Tribal citizens with T2D who used Choctaw Nation Health Services Authority (CNHSA) and Pharmacies and had HbA1c data during 2017-2018 were included in this study. Medication adherence (proportion of days covered [PDC] ≥0.80) was calculated using 2017 CNHSA electronic health record data. RESULTS: Of the 74,000 tribal citizens living on tribal lands, 4,560 were eligible; 32% had HbA1c at or below target (≤7%), 36% were above target (>7 to ≤9%), and 32% were uncontrolled (>9%) in 2017. The percentage of patients with PDC ≥0.80 was 66% for those using biguanides, 72% for sulfonylureas, 75% for dipeptidyl peptidase 4 inhibitors, and 83% for sodium-glucose cotransporter 2 inhibitors. The proportion of patients with HbA1c at or below target increased slightly from 32% in 2017 to 42% in 2018. Higher average PDC in 2017 was associated with lower HbA1c levels in 2018 (ß = -1.143; P < 0.001). CONCLUSIONS: Medication adherence was higher than that found in previous studies using self-report methods in American Indian populations, although a smaller proportion of patients had HbA1c at or below target relative to U.S. adults with T2D. Medication adherence was associated with improved HbA1c levels for most oral glucose-lowering medication classes. Future studies of American Indians should use both longitudinal prescription data from both electronic health records and pharmacy refills.

Medication Adherence and Cardiometabolic Control Indicators Among American Indian Adults Receiving Tribal Health Services: Protocol for a Longitudinal Electronic Health Records Study.

BACKGROUND: American Indian adults have the highest prevalence of type 2 diabetes (T2D) in any racial or ethnic group and experience high rates of comorbidities. Uncontrolled cardiometabolic risk factors-insulin resistance, resulting in impaired glucose tolerance, dyslipidemia, and hypertension-increase the risk of mortality. Mortality is significantly reduced by glucose- and lipid-lowering and antihypertensive medication adherence. Medication adherence is low among American Indian adults living in non-Indian Health Service health care settings. Virtually nothing is known about the nature and extent of medication adherence among reservation-dwelling American Indian adults who primarily receive their medications without cost from Indian Health Service or tribal facilities. Electronic health records (EHRs) offer a rich but underused data source regarding medication adherence and its potential to predict cardiometabolic control indicators (C-MCIs). With the support of the Choctaw Nation of Oklahoma (CNO), we address this oversight by using EHR data generated by this large, state-of-the-art tribal health care system to investigate C-MCIs. OBJECTIVE: Our specific aims are to determine, using 2018 EHR data, the bivariate relationships between medication adherence and C-MCIs, demographics, and comorbidities and each C-MCI and demographics and comorbidities; develop machine learning models for predicting future C-MCIs from the previous year's medication adherence, demographics, comorbidities, and common laboratory tests; and identify facilitators of and barriers to medication adherence within the context of social determinants of health (SDOH), EHR-derived medication adherence, and C-MCIs. METHODS: Drawing on the tribe's EHR (2018-2021) data for CNO patients with T2D, we will characterize the relationships among medication adherence (to glucose- and lipid-lowering and antihypertensive drugs) and C-MCIs (hemoglobin A1c ≤7%, low-density lipoprotein cholesterol <100 mg/dL, and systolic blood pressure <130 mm Hg); patient demographics (eg, age, sex, SDOH, and residence location); and comorbidities (eg, BMI ≥30, cardiovascular disease, and chronic kidney disease). We will also characterize the association of each C-MCI with demographics and comorbidities. Prescription and pharmacy refill data will be used to calculate the proportion of days covered with medications, a typical measure of medication adherence. Using machine learning techniques, we will develop prediction models for future (2019-2021) C-MCIs based on medication adherence, patient demographics, comorbidities, and common laboratory tests (eg, lipid panel) from the previous year. Finally, key informant interviews (N=90) will explore facilitators of and barriers to medication adherence within the context of local SDOH. RESULTS: Funding was obtained in early 2022. The University of Florida and CNO approved the institutional review board protocols and executed the data use agreements. Data extraction is in process. We expect to obtain results from aims 1 and 2 in 2024. CONCLUSIONS: Our findings will yield insights into improving medication adherence and C-MCIs among American Indian adults, consistent with CNO's State of the Nation's Health Report 2017 goal of reducing T2D and its complications.

Social Support and Diabetes Management Among Older American Indians.

Objective: Greater understanding how relationships that can facilitate or impede type 2 diabetes (T2D) management and control among older American Indian people is an overlooked, yet urgently needed strategy. Thus, we examined social support among older American Indian people in relation to their T2D management. Methods: During the fall 2015, we conducted qualitative interviews with 28 participants aged ≥ 60 years who were members of a federally-recognized tribe. Drawing upon the buffering and direct effects theoretical models of how social support affects health, we examined transcribed audio recordings of the interviews with a systematic text analysis approach. We used a low-inference qualitative descriptive design to provide a situated understanding of participants' life experiences using their naturalistic expressions. Results: The mean age of our participants was 73.0 ± 6.4 years with a mean HbA1c of 7.3 ± 1.5. Main social support sources were family, clinicians/formal services, community/culture, and spiritual/God. All four common social support types were represented, namely emotional, instrumental, informational, and appraisal support with most being instrumental in nature. A prominent gender difference was seen with respect to men receiving more instrumental support family/friends support than women. Discussion: Value orientations among American Indian people often reflect extended social systems and interdependence. A deeper understanding is needed of how social relationships can be better leveraged to aid in effective T2D management among older American Indian people. The development and implementation of evidence-based social network interventions with an assets-based orientation that build upon the cultural value of reciprocity hold promise to improve T2D outcomes of older American Indian people.

Nephrology and Palliative Care Providers' Beliefs in Engaging American Indian Patients in Palliative Care Conversations.

Background: American Indians with chronic kidney disease are twice as likely to develop end-stage renal disease. Palliative care is underused by American Indian patients, although studies show it is not due to an unwillingness to engage in conversations about end of life. Objectives: The aim of our study was to explore the experiences and beliefs of Nephrology and palliative care providers of one tribal community with respect to engaging patients and family members in palliative care. Design: Using an interview guide, individual, in-depth interviews were conducted between March and August 2019 with eligible participants. We used constant comparative analysis of interview transcripts. Setting and Subjects: Our study sample included eight participants, including four Nephrology providers and four palliative care providers. Results: We identified five themes, including (1) providers' stereotypes, (2) patients' mistrust of providers, (3) patients' end-of-life preferences, (4) available community resources, and (5) patients' family dynamics. Negative stereotypes were present in every theme, although most participants did not acknowledge the role stereotypes played in establishing trust and building therapeutic relationships conducive to end-of-life discussions. Conclusion: Providers serving American Indian patients with kidney disease should consider training in trauma informed care and cultural sensitivity. Negative stereotypes of American Indian patients may impact provider's ability to build trust, a key component of end-of-life conversations, and contribute to misperceptions related to family dynamics, end-of-life preferences, and available community resources.

Social determinants of obesity in American Indian and Alaska Native peoples aged ≥ 50 years.

OBJECTIVE: American Indian and Alaska Native peoples (AI/ANs) have a disproportionately high rate of obesity, but little is known about the social determinants of obesity among older AI/ANs. Thus, our study assessed social determinants of obesity in AI/ANs aged ≥ 50 years. DESIGN: We conducted a cross-sectional analysis using multivariate generalized linear mixed models to identify social determinants associated with the risk of being classified as obese (BMI ≥ 30.0 kg/m2). Analyses were conducted for the total study population and stratified by median county poverty level. SETTING: Indian Health Service (IHS) data for AI/ANs who used IHS services in FY2013. PARTICIPANTS: 27,696 AI/ANs aged ≥ 50 years without diabetes. RESULTS: Mean BMI was 29.8 ± 6.6 with 43% classified as obese. Women were more likely to be obese than men, and younger ages were associated with higher obesity risk. While having Medicaid coverage was associated with lower odds of obesity, private health insurance was associated with higher odds. Living in areas with lower rates of educational attainment and longer drive times to primary care services were associated with higher odds of obesity. Those who lived in a county where a larger percentage of people had low access to a grocery store were significantly less likely to be obese. CONCLUSIONS: Our findings contribute to the understanding of social determinants of obesity among older AI/ANs and highlight the need to investigate AI/AN obesity, including longitudinal studies with a life course perspective to further examine social determinants of obesity in older AI/ANs.

Cardiometabolic Conditions and All-Cause Dementia Among American Indian and Alaska Native People.

BACKGROUND: Diabetes, hypertension, and cardiovascular disease (CVD) are modifiable lifestyle-related cardiometabolic conditions associated with dementia. Yet, little is known regarding these associations among American Indian and Alaska Native (AI/AN) people. Thus, we examined the association of diabetes, hypertension, and CVD with all-cause dementia among AI/ANs aged 65 years and older. METHOD: This was a cross-sectional analysis of the Indian Health Service Improving Health Care Delivery Data Project. Our study population was a 1:1 matched sample of 4 074 AI/ANs aged 65 years and older and Indian Health Service active users during fiscal year 2013. We employed International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes for all-cause dementia, hypertension, and CVD. Diabetes was measured with a validated algorithm to identify adults with diabetes that uses diagnoses, laboratory test results, and medication criteria. RESULTS: Multivariable analyses revealed that diabetes and CVD were associated with increased odds of all-cause dementia and hypertension was not. Cardiovascular disease types associated with all-cause dementia differed with cerebrovascular disease having the strongest association. Analyses stratified by gender revealed that diabetes and CVD were associated with increased odds of all-cause dementia for women and only CVD was associated with all-cause dementia for men. CONCLUSIONS: Training and support of primary care clinicians, addressing cultural considerations, and ensuring inclusion of AI/ANs in research are steps that could help meet AI/AN people's needs. Our findings underscore to the importance of improved management and control of diabetes and CVD, which may lead to the prevention of dementia among older AI/ANs.

Older Adults in the United States and COVID-19: A Qualitative Study of Perceptions, Finances, Coping, and Emotions.

Introduction: Older adults have the poorest coronavirus (COVID-19) prognosis with the highest risk of death due to complications, making their COVID-19 experiences particularly important. Guided by the stress-appraisal-coping theoretical model, we sought to understand COVID-related perceptions and behaviors of older adults residing in the United States. Materials and Methods: We used convenience sampling to recruit persons with the following inclusion criteria: Aged ≥ 65 years, English fluency, and U.S. residency. Semi structured in-depth interviews were conducted remotely and audio recorded between April 25, 2020 and May 7, 2020. Interviews were professionally transcribed with a final study sample of 43. A low-inference qualitative descriptive design was used to provide a situated understanding of participants' life experiences using their naturalistic expressions. Results: The mean age of participants was 72.4 ± 6.7. Slightly over half were female (55.8%), 90.6% were White, and 18.6% lived alone. The largest percentages of participants resided in a rural area (27.9%) or small city (25.6%). We identified four themes, including (1) risk perception, (2) financial impact, (3) coping, and (4) emotions. Most participants were aware of their greater risk for poor COVID-19 outcomes but many did not believe in their increased risk. Financial circumstances because of the pandemic varied with largely no financial impacts, while others reported negative impacts and a few reported positive impacts. Coping was problem- and emotion-focused. Problem-focused coping included precautionary efforts and emotion-focused coping included creating daily structure, pursuing new and/or creative activities, connecting with others in new ways, and minimizing news media exposure. Overall, emotional health was negatively affected by the pandemic although some participants reported positive emotional experiences. Conclusions: Perceiving themselves as high risk for COVID-19 complications, older adults used precautionary measures to protect themselves from contracting the virus. The precautionary measures included social isolation, which can negatively affect mental health. Older adults will need to be resourceful and draw on existing resources to cope, such as engaging in creative activities and new strategies to connect with others. Our findings underscore the importance of the preservation of mental health during extended periods of isolation by taking advantage of low-to-no-cost existing resources.

Diabetes and health-related quality of life among American Indians: the role of psychosocial factors.

PURPOSE: Little is known about the association of psychosocial factors with health-related quality of life (HRQoL) among American Indians with type 2 diabetes (T2D). This study described functional social support, emotional support, coping, resilience, post-traumatic stress disorder, and HRQoL, among American Indians by diabetes status and, among those with diabetes, examined the association of these factors with HRQoL. METHODS: Using data from the Cherokee Nation Health Survey collected between 2017 and 2019, we evaluated differences in each measure of interest according to diabetes status, using t-test and Chi-squared tests of association. We used weighted multiple logistic regression to examine associations between multiple psychosocial factors and HRQoL among those with diabetes. RESULTS: Compared to individuals without diabetes, participants with diabetes rated their functional social support (4.62 vs. 4.56, respectively) and coping (2.65 vs. 2.61, respectively) slightly lower and were more likely to report ≥ 15 days of poor physical (14% vs. 26%, respectively) and mental health (14% vs. 17%, respectively) in the past month. Odds of reporting poor overall health increased more than sixfold for those who were dissatisfied/very dissatisfied with life (AOR = 6.70). Resilience scores reduced odds of reporting ≥ 15 days with poor physical health, while experiences of post-traumatic stress doubled these odds. CONCLUSION: Our study yielded insights into the risk as well as protective factors associated with diabetes outcomes in a large sample of American Indians with T2D. Researchers should design pragmatic trials that deepen understanding of preventive as well as treatment leverage through greater attention to experiences that compromise HRQoL.

Type 2 diabetes management among older American Indians: beliefs, attitudes, and practices.

Objective: The purpose of this study was to examine beliefs, attitudes, and practices of older American Indians regarding their type 2 diabetes mellitus (T2DM) management. T2DM is one of the leading causes of morbidity and mortality among American Indians. American Indians are more than twice as likely to have T2DM and have over three times a T2DM mortality rate as Whites. Design: Study participants were older members of a federally recognized tribe who had T2DM. A low-inference qualitative descriptive design was used. Data were collected through semi-structured in-depth qualitative interviews with a mixed inductive, deductive, and reflexive analytic team process. Results: Our study sample included 28 participants with a mean age of 73.0 ± 6.4 years of whom 16 (57%) were women. Participants' mean self-confidence score of successful T2DM management was 8.0 ± 1.7 on a scale from 1 to 10 with 10 representing the greatest amount of confidence. Participants' mean HbA1c was 7.3% ± 1.5%. Overall, participants discussed T2DM management within five themes: 1) sociocultural factors, 2) causes and consequences, 3) cognitive and affective assessment, 4) diet and exercise, and 5) medical management. Conclusions: It is important to be aware of the beliefs and attitudes of patients. Lay understandings can help identify factors underlying health and illness behaviors including motivations to maintain healthy behaviors or to change unhealthy behaviors. Such information can be helpful for health educators and health promotion program staff to ensure their efforts are effective and in alignment with patients' realities.

Putting Self-Management in the Context of Community-Dwelling American Indians Living With Type 2 Diabetes.

PURPOSE: The purpose of this qualitative descriptive study was to examine the National Standards for Diabetes Self-Management Education and Support (DSMES) defined diabetes self-care behaviors (healthy eating, being active, taking medication, monitoring, problem solving, reducing risk, and healthy coping) in the context of older community-dwelling American Indians (AIs). METHODS: Secondary theme analysis of transcribed semistructured qualitative interview data from 28 participants in the Native Elder Care Study aged >60 years identified factors that influence the DSMES self-care behaviors in the context of community-dwelling AIs. RESULTS: Four themes that characterized barriers, facilitators, and opportunities for DSMES to support self-care behaviors included community food security, care partners in self-care, community opportunities for diabetes support, and blending of both health worlds. CONCLUSION: Tribal communities have contemporary strengths and cultural traditions that can be activated to enhance diabetes self-management education and support. Diabetes educators can work in tandem with community health representatives to strengthen the social and community support within which individual AIs with type 2 diabetes mellitus live. Community-based participatory research with AI caregivers, dyads, families, youth, and Indian Health Service clinicians may help to improve tribal food policy and school health initiatives, as well as develop intergenerational interventions for modeling effective diabetes self-management.

Depressive Symptoms and All-Cause Mortality in Older American Indians with Type 2 Diabetes Mellitus.

OBJECTIVES: American Indians experience disproportionately high rates of poor mental health and type 2 diabetes mellitus (T2DM). We examined the association between depressive symptoms and all-cause mortality in older American Indians with T2DM. DESIGN: We used the Native Elder Care Study survey data from community-dwelling American Indians aged 55 years or older, linked to data extracted from participants' electronic health records. We focused on those who had an International Classification of Diseases-Ninth Revision diagnosis of T2DM in their electronic health records. SETTING: The study was conducted with a federally-recognized tribe with approximately 16,000 enrolled members, most of whom reside on or near tribally-owned lands that span several rural counties. PARTICIPANTS: Participants were among the Native Elder Care Study participants with a final analytic sample of 222. MEASUREMENTS: We measured depressive symptoms with the Centers for Epidemiologic Studies-Depression (CES-D) scale. We used Cox proportional hazard models to examine the association between depressive symptoms and all-cause mortality in the final analytic sample of 222 subjects. RESULTS: Survival curves revealed that individuals in the third and fourth CES-D scale categories had higher mortality than those in the first and second categories. Mortality risk was significantly higher for participants with CES-D scale scores in the third highest compared with the lowest category (hazard ratio = 2.07; 95% confidence interval = 1.07-4.04), after adjustment for demographic characteristics, health behaviors, obesity, and prevalent T2DM complications. Analyses with the CES-D scale as a continuous variable also showed a positive association with mortality. CONCLUSION: The impact of mental health on older American Indians with T2DM is often overlooked, yet it is vital to clinical and public health practice. Our findings underscore the importance of addressing the mental health needs of this population, particularly because depression in older patients is often undetected or inadequately treated.

Traumatic Stress, Social Support, and Health Among Older American Indians: The Native Elder Care Study.

OBJECTIVES: To estimate the prevalence of lifetime traumatic experiences, describe related symptoms of traumatic stress, and examine their association with perceived social support and physical and mental health among older American Indians. METHOD: Analyses of existing interview data from the Native Elder Care Study, a random age-stratified sample of 505 tribal members ≥55 years of age conducted in partnership with a large Southeastern tribe. Interviews assessed trauma exposure, traumatic stress, measures of social support, and physical and mental health status. RESULTS: Overall, 31% of participants had experienced a traumatic event; of these, 43% reported traumatic stress at the time of the interview. Higher perceived social support was associated with a reduced prevalence of traumatic stress. Compared to their counterparts without traumatic stress, women participants reporting traumatic stress reported more symptoms of depression, and both symptomatic men and women had a higher prevalence of cardiovascular disease and chronic pain. DISCUSSION: Traumatic stress was associated with less perceived social support and poorer health. Social support was not found to moderate the relationship between traumatic stress and physical and mental health.

Identifying risk and protective factors related to depressive symptoms among Northern Plains American Indian women cancer survivors.

Cancer is the leading cause of death among American Indian and Alaska Native (AIAN) women, and depressive symptoms have been linked to higher mortality, but research on depressive symptoms among AIAN cancer patients has been scant. The purpose of this exploratory study was, using the Framework of Historical Oppression, Resilience, and Transcendence, to examine risk and protective factors related to depressive symptoms in American Indian (AI) women cancer survivors. We examined the relationships of adverse childhood experiences (ACE), perceived health status, resilience, and social support with depressive symptoms in Northern Plains AI women cancer survivors. We used a cross-sectional design with purposive sampling of 73 female cancer survivors (aged 18 years or older) between June 2014 and February 2015. Hierarchical multiple regression was used to test three sets of variables in relation to depressive symptoms: (1) sociodemographics, (2) risk factors (ACE and perceived health), and (3) protective factors (psychological resilience and social support). Approximately 47 percent of participants had probable depressive symptoms. Depressive symptoms were inversely associated with perceived health, psychological resilience, and social support. These results support bolstering existing social support among AI cancer patients and survivors as well as prevention and intervention efforts that strengthen resilience.

Lower body functioning and correlates among older American Indians: The Cerebrovascular Disease and Its Consequences in American Indians Study.

BACKGROUND: More than six million American Indians live in the United States, and an estimated 1.6 million will be aged ≥65 years old by 2050 tripling in numbers since 2012. Physical functioning and related factors in this population are poorly understood. Our study aimed to assess lower body functioning and identify the prevalence and correlates of "good" functioning in a multi-tribe, community-based sample of older American Indians. METHODS: Assessments used the Short Physical Performance Battery (SPPB). "Good" lower body functioning was defined as a total SPPB score of ≥10. Potential correlates included demographic characteristics, study site, anthropometrics, cognitive functioning, depressive symptomatology, grip strength, hypertension, diabetes mellitus, heart disease, prior stroke, smoking, alcohol use, and over-the-counter medication use for arthritis or pain. Data were collected between 2010 and 2013 by the Cerebrovascular Disease and Its Consequences in American Indians Study from community-dwelling adults aged ≥60 years (n = 818). RESULTS: The sample's mean age was 73 ± 5.9 years. After adjustment for age and study site, average SPPB scores were 7.0 (95% CI, 6.8, 7.3) in women and 7.8 (95% CI, 7.5, 8.2) in men. Only 25% of the sample were classified with "good" lower body functioning. When treating lower body functioning as a continuous measure and adjusting for age, gender, and study site, the correlates of better functioning that we identified were younger age, male gender, married status, higher levels of education, higher annual household income, Southern Plains study site, lower waist-hip ratio, better cognitive functioning, stronger grip strength, lower levels of depressive symptomatology, alcohol consumption, and the absence of hypertension, diabetes mellitus, and heart disease. In our fully adjusted models, correlates of "good" lower body functioning were younger age, higher annual household income, better cognitive functioning, stronger grip, and the absence of diabetes mellitus and heart disease. CONCLUSIONS: These results suggest that "good" lower body functioning is uncommon in this population, whereas its correlates are similar to those found in studies of other older adult populations. Future efforts should include the development or cultural tailoring of interventions to improve lower body functioning in older American Indians.

Lifetime Trauma and Depressive Symptomatology Among Older American Indians: The Native Elder Care Study.

We examined the association between lifetime traumatic events with or without trauma response symptoms and depressive symptomatology in American Indians aged ≥ 55 years from a tribe in the Southeastern US (N = 362). Twenty-three percent of the sample experienced a traumatic event without trauma-response symptoms, whereas 14% experienced a traumatic event with at least one trauma-response symptom. After adjustment for sociodemographic characteristics and social support, participants who experienced a traumatic event with one or more trauma-response symptoms had higher odds of clinically relevant depressive symptomatology compared to (1) those who never experienced a traumatic event [odds ratio (OR) 3.2, p < 0.05], (2) and those who experienced a traumatic event without further symptoms (OR 3.7, p < 0.05). Our results suggest that mental health providers who serve older American Indians should consider the experience of traumatic events followed with response symptoms as a potential risk factor for further disruptions in psychological functioning.

Psychometric examination of the Center for Epidemiologic Studies Depression scale with older American Indians: The Native Elder Care Study.

Measuring mental health accurately is an important endeavor for screening purposes. Depression scales, such as the Center for Epidemiologic Studies Depression (CES-D) scale, have been well-established among different populations. Yet, little work has been done to examine the reliability and validity of the CES-D among older American Indians and Alaska Natives. The purpose of our study was to examine the factor structure, reliability, and concurrent validity of the full 20-item and abbreviated 12-item CES-D scale with a sample of older American Indians. Our findings demonstrate excellent internal reliability and concurrent validity of the full and abbreviated CES-D scales in our study sample.
