Comorbidity among older American Indians: the native elder care study

"'We'd Just Patch Ourselves up': Preference for Holistic Approaches to Healthcare and Traditional Medicine among Members of a State-Recognized Tribe"

Background:Health disparities between Native Americans and white Americans persist due to a variety of factors, including colonization, poverty, and racism. Racist interpersonal interactions between nurses and other healthcare providers and tribal members may also contribute to reluctance among Native Americans to engage with Western healthcare systems. Purpose: The purpose of this study was to better understand the healthcare experiences of members of a state-recognized Gulf Coast tribe. Methods: In partnership with a community advisory board, 31 semistructured interviews were conducted, transcribed, and analyzed utilizing a qualitative description approach. Results: All participants mentioned their preferences, views about, or experiences of using natural or traditional medicine approaches (referenced 65 times). Emergent themes include (a) preference for and use of traditional medicine; (b) resistance to western healthcare systems; (c) preference for holistic approaches to health; and (d) negative provider interpersonal interactions contributing to reluctance in seeking care. Conclusion: These findings suggest that integrating a holistic conceptualization of health and traditional medicine practices into Western healthcare settings would benefit Native Americans.

"'You Just Want to Give me Some Medicine and be on my Way': Preferences, Beliefs, and Experiences Related to Western Medication among Members of a State-Recognized Tribe"

Background: Native American/American Indian (NA/AI) people have higher rates of chronic disease, including substance use and mental health disorders, compared to White Americans. Though pharmaceuticals can be helpful in addressing many chronic healthcare conditions, many people do not take medications as prescribed. NA/AI identity has been found to be associated with lower rates of medication adherence compared to White Americans. Purpose: The purpose of this study is to better understand NA/AI women's perceptions, beliefs, and experiences related to medication. Methods: Thirty-one semi-structured interviews were conducted with NA/AI women from a state-recognized tribe located in the Gulf South. Interviews were transcribed and analyzed using a qualitative description approach. Results: Eighteen women discussed their experiences using medications when asked about their healthcare experiences. Participants identified the following themes in their discussion of medication: (a) Cost of Medication as a Barrier; (b) Negative Side Effects of Western Medication; (c) Fear of Resistance and Dependence; (d) Preference for Traditional Medicine or None; and (e) Lack of Communication around Medications from Providers. Conclusion: Our findings support the growing call for cultural safety within medical settings and integrating NA/AI conceptualizations of health and well-being and traditional practices into western healthcare settings to better support NA/AI people.

Sociodemographic Disparities in Preoperative Visual Acuity and Cataract Surgery Utilization in the San Francisco Bay Area

OBJECTIVE

We examined whether cataract surgery utilization and preoperative visual acuity were associated with patient-specific factors, including ocular findings and comorbidities, general biomedical factors, and/or sociodemographic factors.

DESIGN

Retrospective, cross-sectional study.

SUBJECTS, PARTICIPANTS, AND/OR CONTROLS

We reviewed the electronic health records of patients from 2012 to 2022 who were examined and followed for at least 2 years by an eye care provider at University of California San Francisco Health (UCSF Health) and who had cataract in at least one eye associated with best-corrected visual acuity of 20/25 or worse. Data include ocular factors (e.g., best-corrected visual acuity, lens opacity grade, diagnoses of glaucoma, and/or age-related macular degeneration), biomedical comorbidities, and sociodemographic factors including race/ethnicity, health insurance coverage, primary language spoken, and social vulnerability index.

METHODS

Logistic and multivariate regression analyses.

MAIN OUTCOME MEASURES

We examined cataract surgery utilization and preoperative best-corrected visual acuity.

RESULTS

Compared to White and Asian patients, Black patients had the lowest rates of cataract surgery utilization and the poorest mean preoperative visual acuities, with Hispanic patients following in second place in both categories. However, when the analysis controlled for sociodemographic and biomedical factors, Medicaid insurance and speaking Chinese as a primary language emerged as significant associations. In addition, higher cataract surgery utilization rates were associated with worse preoperative best-corrected visual acuity, a concurrent diagnosis of glaucoma, and a concurrent diagnosis of macular degeneration. Worse preoperative visual acuity was associated with Spanish or Chinese language preference, Medicaid status, and glaucoma diagnosis; poorer preoperative visual acuity was only weakly correlated with increased social vulnerability.

CONCLUSIONS

After adjusting for other biomedical and sociodemographic variables, having Medicaid insurance and being a non-English speaker were the factors most notably associated with reduced cataract surgery utilization and poorer preoperative visual acuity. Health insurance and language barriers, as well as other biomedical and sociodemographic factors, may explain a large proportion of the racial disparities in both cataract surgery utilization and preoperative visual acuity observed among Black and Hispanic patients. Chinese-speaking patients with limited English proficiency are a vulnerable subgroup that exhibits lower rates of cataract surgery utilization and higher degrees of visual loss prior to undergoing cataract surgery compared to other Asian patients.

A Review of the Prevalence of Ophthalmologic Diseases in Native American Populations

PURPOSE

Compared with the general population in North America, Native American/American Indian and Alaska Native (AI/AN) populations experience a disparate prevalence of eye diseases. Visual impairment is a barrier to communication, interferes with academic and social success, and decreases overall quality of life. The prevalence of ocular pathology could serve as an indicator of health and social disparities. Therefore, the objective of this research was to perform a thorough review comparing the prevalence of common ophthalmological pathologies between AI/AN and non-AI/AN individuals in North America.

DESIGN

Retrospective, cross-sectional study.

METHODS

A total of 57 articles were retrieved and reviewed, and 14 met the criteria outlined for inclusion. These articles were retrieved from PubMed, MEDLINE, and ISI Web of Knowledge. Only studies that were peer reviewed in the last 25 years and reported on the prevalence of eye diseases in AI/AN compared with a non-AI/AN population met criteria.

RESULTS

Rates of retinopathy, cataracts, visual impairment, and blindness were clearly higher for AI/AN compared with non-AI/AN counterparts. Although rates of macular degeneration and glaucoma were similar between AI/AN and non-AI/AN populations, the treatment rates were lower and associated with poorer outcomes in AI/AN individuals.

CONCLUSIONS

There are considerable inequities in the prevalence and treatment rates of ophthalmologic conditions in AI/AN individuals. A likely explanation is the barrier of lack of access to adequate health and eye care. Because of substantial underinsurance and geographic variability, attention needs to be brought to expanding eye care access to AI/AN communities. The results are subject to the availability of appropriate technology, health literacy, and language.

Alzheimer's disease and its related dementias in US Native Americans: A major public health concern

Alzheimer's disease (AD) and Alzheimer's related dementias (ADRD) are growing public health concerns in aged populations of all ethnic and racial groups. AD and ADRD are caused by multiple factors, such as genetic mutations, modifiable and non-modifiable risk factors, and lifestyle. Studies of postmortem brains have revealed multiple cellular changes implicated in AD and ADRD, including the accumulation of amyloid beta and phosphorylated tau, synaptic damage, inflammatory responses, hormonal imbalance, mitochondrial abnormalities, and neuronal loss. These changes occur in both early-onset familial and late-onset sporadic forms. Two-thirds of women and one-third of men are at life time risk for AD. A small proportion of total AD cases are caused by genetic mutations in amyloid precursor protein, presenilin 1, and presenilin 1 genes, and the APOE4 allele is a risk factor. Tremendous research on AD/ADRD, and other comorbidities such as diabetes, obesity, hypertension, and cancer has been done on almost all ethnic groups, however, very little biomedical research done on US Native Americans. AD/ADRD prevalence is high among all ethnic groups. In addition, US Native Americans have poorer access to healthcare and medical services and are less likely to receive a diagnosis once they begin to exhibit symptoms, which presents difficulties in treating Alzheimer's and other dementias. One in five US Native American people who are 45 years of age or older report having memory issues. Further, the impact of caregivers and other healthcare aspects on US Native Americans is not yet. In the current article, we discuss the history of Native Americans of United States (US) and health disparities, occurrence, and prevalence of AD/ADRD, and shedding light on the culturally sensitive caregiving practices in US Native Americans. This article is the first to discuss biomedical research and healthcare disparities in US Native Americans with a focus on AD and ADRD, we also discuss why US Native Americans are reluctant to participate in biomedical research.

20-year trends in multimorbidity by race/ethnicity among hospitalized patient populations in the United States

BACKGROUND

The challenges presented by multimorbidity continue to rise in the United States. Little is known about how the relative contribution of individual chronic conditions to multimorbidity has changed over time, and how this varies by race/ethnicity. The objective of this study was to describe trends in multimorbidity by race/ethnicity, as well as to determine the differential contribution of individual chronic conditions to multimorbidity in hospitalized populations over a 20-year period within the United States.

METHODS

This is a serial cross-sectional study using the Nationwide Inpatient Sample (NIS) from 1993 to 2012. We identified all hospitalized patients aged ≥ 18 years old with available data on race/ethnicity. Multimorbidity was defined as the presence of 3 or more conditions based on the Elixhauser comorbidity index. The relative change in the proportion of hospitalized patients with multimorbidity, overall and by race/ethnicity (Black, White, Hispanic, Asian/Pacific Islander, Native American) were tabulated and presented graphically. Population attributable fractions were estimated from modified Poisson regression models adjusted for sex, age, and insurance type. These fractions were used to describe the relative contribution of individual chronic conditions to multimorbidity over time and across racial/ethnic groups.

RESULTS

There were 123,613,970 hospitalizations captured within the NIS between 1993 and 2012. The prevalence of multimorbidity increased in all race/ethnic groups over the 20-year period, most notably among White, Black, and Native American populations (+ 29.4%, + 29.7%, and + 32.0%, respectively). In both 1993 and 2012, Black hospitalized patients had a higher prevalence of multimorbidity (25.1% and 54.8%, respectively) compared to all other race/ethnic groups. Native American populations exhibited the largest overall increase in multimorbidity (+ 32.0%). Furthermore, the contribution of metabolic diseases to multimorbidity increased, particularly among Hispanic patients who had the highest population attributable fraction values for diabetes without complications (15.0%), diabetes with complications (5.1%), and obesity (5.8%).

CONCLUSIONS

From 1993 to 2012, the secular increases in the prevalence of multimorbidity as well as changes in the differential contribution of individual chronic conditions has varied substantially by race/ethnicity. These findings further elucidate the racial/ethnic gaps prevalent in multimorbidity within the United States.

PRIOR PRESENTATIONS

Preliminary finding of this study were presented at the Society of General Internal Medicine (SGIM) Annual Conference, Washington, DC, April 21, 2017.

Health Disparity Curricula for Ophthalmology Residents: Current Landscape, Barriers, and Needs

Background  Social determinants of health play a critical role in visual health outcomes. Yet, there exists no structured curriculum for ophthalmology residents to identify and address health disparities relevant to eye care or no a standard assessment of health disparities education within ophthalmology residency programs. This study aims to characterize current health disparity curricula in ophthalmology residency programs in the United States, determine resident confidence in addressing health disparities in the clinical setting, and identify perceived barriers and needs of program directors (PDs) and residents in this area. Design  This was a cross-sectional survey study. Methods  A closed-ended questionnaire with comments was distributed to the Accreditation Council for Graduate Medical Education-accredited ophthalmology residency PDs and residents in April 2021 and May 2022. The questionnaire solicited characteristics of any existing health disparity curricula, PD and resident perceptions of these curricula, and residents' experience with and confidence in addressing health disparities in the delivery of patient care. Results  In total, 29 PDs and 96 residents responded. Sixty-six percent of PDs stated their program had a formal curriculum compared to fifty-three percent of residents. Forty-one percent of PDs and forty-one percent of residents stated their program places residents in underserved care settings for more than 50% of their training. Most residents (72%) were confident in recognizing health disparities. Sixty-six percent were confident in managing care in the face of disparities and fifty-nine percent felt they know how to utilize available resources. Residents were most concerned with the lack of access to resources to help patients. Forty-five percent of PDs felt the amount of time dedicated to health disparities education was adequate. Forty-nine percent of residents reported they felt the amount of training they received on health disparities to be adequate. The top barrier to curriculum development identified by PDs was the availability of trained faculty to teach. Time in the curriculum was a major barrier identified by residents. Conclusions  Roughly half of ophthalmology residency programs who responded had a health disparity curriculum; however, both PDs and residents felt inadequate time is dedicated to such education. National guidance on structured health disparity curricula for ophthalmology residents may be warranted as a next step.

Trajectories of Successful Aging Among Older Adults in Aotearoa New Zealand

Successful aging was defined as having no multimorbidity, high functional capacity, active life engagement, and good health-related quality of life. This study analyzed data from 1433 older adults who were followed up for 12 years across seven waves from the New Zealand Health, Work and Retirement study by examining the trajectories of successful aging. Latent growth curve modeling was used to assess the growth factors of successful aging trajectories of older adults. The mean successful aging score was 3.53 (range: 0-6) in 2006 and linearly declined by 0.064 units every year. Those with higher successful aging scores at baseline had a slower decline. Successful aging scores were lower among females, Māori, and those aged 65 years and above at baseline. The findings from this study suggest that gender and ethnic inequalities play significant roles in successful aging among older adults in New Zealand.

"I Think [Western] Healthcare Fails Them": Qualitative Perspectives of State-recognized Women Tribal Members on Elders' Healthcare Access Experiences

Elder tribal members are important cultural and spiritual leaders and experts among many American Indian and Alaska Native (AI/AN) cultures. AI/AN Elders play a key role in the maintenance and transmission of traditional cultural knowledge and practices and are highly valued members of AI/AN communities. AI/AN populations face disparities in healthcare outcomes, and the healthcare needs of AI/AN Elders remain an understudied area of research, particularly among tribes in the South and for tribes who do not have federal recognition. Qualitative data was collected through semi-structured interviews among 31 women, all of whom are members of a state-recognized Tribe in the Southern United States. While the interview questions were specific to their own reproductive healthcare experiences, repeated concerns were voiced by the women regarding the health of the Elders in their community. Key findings captured several concerns/barriers regarding Elders' healthcare experiences including: (a) Language and communication barriers between Elders and healthcare workers; (b) Prior negative experiences with Western medicine; (c) Lasting impacts of educational discrimination; (d) Concerns over self-invalidation; (e) Transportation barriers; and (f) Need for community programs. Issues related to these barriers have resulted in a concern that Elders are not receiving the full benefit of and access to Western healthcare systems. The purpose of this analysis was to highlight the concerns voiced by women tribal members on the health and wellbeing of Elders in their community. Opportunities related to the importance of prioritizing and improving AI/AN Elders' healthcare experiences and access are also described.

COVID-19 Among Non-Hispanic American Indian and Alaska Native People Residing in Urban Areas Before and After Vaccine Rollout-Selected States and Counties, United States, January 2020-October 2021

Objectives. To evaluate COVID-19 disparities among non-Hispanic American Indian/Alaska Native (AI/AN) and non-Hispanic White persons in urban areas. Methods. Using COVID-19 case surveillance data, we calculated cumulative incidence rates and risk ratios (RRs) among non-Hispanic AI/AN and non-Hispanic White persons living in select urban counties in the United States by age and sex during January 22, 2020, to October 19, 2021. We separated cases into prevaccine (January 22, 2020-April 4, 2021) and postvaccine (April 5, 2021-October 19, 2021) periods. Results. Overall in urban areas, the COVID-19 age-adjusted rate among non-Hispanic AI/AN persons (n = 47 431) was 1.66 (95% confidence interval [CI] = 1.36, 2.01) times that of non-Hispanic White persons (n = 2 301 911). The COVID-19 prevaccine age-adjusted rate was higher (8227 per 100 000; 95% CI = 6283, 10 770) than was the postvaccine rate (3703 per 100 000; 95% CI = 3235, 4240) among non-Hispanic AI/AN compared with among non-Hispanic White persons (2819 per 100 000; 95% CI = 2527, 3144; RR = 1.31; 95% CI = 1.17, 1.48). Conclusions. This study highlights disparities in COVID-19 between non-Hispanic AI/AN and non-Hispanic White persons in urban areas. These findings suggest that COVID-19 vaccination and other public health efforts among urban AI/AN communities can reduce COVID-19 disparities in urban AI/AN populations.

Disparities in Vision Health and Eye Care

Significant disparities in vision health and eye care exist. To achieve health equity, we must understand the root causes and drivers of health disparities and inequities, including social determinants of health and systemic racism.

A Systematic Review of Interventions to Increase Physical Activity Among American Indian and Alaska Native Older Adults

BACKGROUND AND OBJECTIVES

Physical activity (PA) is a powerful protective factor known to reduce risk for chronic conditions across the life span. PA levels are lower among American Indians and Alaska Natives (AIANs) when compared with other racial/ethnic groups and decrease with age. This evidence justifies a synthesis of current intervention research to increase PA levels among AIANs. This systematic review examines completed interventions to increase PA among AIAN older adults and considers recommended practices for research with Indigenous communities.

RESEARCH DESIGN AND METHODS

The systematic review was designed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement for systematic review protocols and reporting guidelines. Three electronic databases, PubMed, Web of Science, and PsycINFO, were searched for academic literature. Trials investigating interventions to increase PA among AIAN adults older than 50 years were eligible. The Quality Assessment Tool for Quantitative Studies was used to evaluate the quality of evidence.

RESULTS

Three published trials were identified, including one group-level, clinic-based and two individual-level, home-based interventions. All were 6 weeks in duration, took place in urban areas, and used self-report PA measures. Findings indicated an overall increase in PA levels, improved PA-related outcomes, and improved psychosocial health among participants. None described community-engaged or culture-centered research strategies.

DISCUSSION AND IMPLICATIONS

The narrow yet promising evidence represents a need for expanded research and a call to action for using culture-centered strategies. An advanced understanding of cultural and contextual aspects of PA may produce more impactful interventions, supporting health and mobility across the life span.

Patterns of Healthcare Use and Mortality After Alzheimer's Disease or Related Dementia Diagnosis Among Alaska Native Patients: Results of a Cluster Analysis in a Tribal Healthcare Setting

Background

Alaska Native and American Indian (AN/AI) people represent a rapidly aging population with disproportionate burdens of Alzheimer's disease and related dementias (ADRD) risk factors.

Objective

To characterize healthcare service use patterns and mortality in the years following ADRD diagnosis for patients in an Alaska Native Tribal health system.

Methods

The study sample included all AN/AI patients aged 55 or older with an ADRD diagnosis who were seen between 2012-2018 (n = 407). We used cluster analysis to identify distinct patterns of healthcare use for primary care, emergency and urgent care, inpatient hospital stays, and selected specialty care. We compared demographic and clinical factors between clusters and used regression to compare mortality.

Results

We identified five clusters of healthcare service use patterns after ADRD diagnosis: 1) people who use a low amount of all services (n = 107), 2) people who use a high amount of all services (n = 60), 3) people who use a high amount of primary and specialty care (n = 105), 4) people who use a high amount of specialty care (n = 65), and 5) people who use a high amount of emergency and urgent care (n = 70). The cluster with the highest use had the greatest proportion of comorbidities and had a 2.3-fold increased risk of mortality compared to the cluster with the lowest healthcare service use.

Conclusion

Results indicate that those receiving the most services had the greatest healthcare-related needs and increased mortality. Future research could isolate factors that predict service use following ADRD diagnosis and identify other differential health risks.

Structural Racism, Place, and COVID-19: A Narrative Review Describing How We Prepare for an Endemic COVID-19 Future

Background:

Place is a social determinant of health, as recently evidenced by COVID-19. Previous literature surrounding health disparities in the United States often fails to acknowledge the role of structural racism on place-based health disparities for historically marginalized communities (i.e., Black and African American communities, Hispanic/Latinx communities, Indigenous communities [i.e., First Nations, Native American, Alaskan Native, and Native Hawaiian], and Pacific Islanders). This narrative review summarizes the intersection between structural racism and place as contributors to COVID-19 health disparities.

Methods:

This narrative review accounts for the unique place-based health care experiences influenced by structural racism, including health systems and services and physical environment. We searched online databases for peer-reviewed and governmental sources, published in English between 2000 and 2021, related to place-based U.S. health inequities in historically marginalized communities. We then narrate the link between the historical trajectory of structural racism and current COVID-19 health outcomes for historically marginalized communities.

Results:

Structural racism has infrequently been named as a contributor to place as a social determinant of health. This narrative review details how place is intricately intertwined with the results of structural racism, focusing on one's access to health systems and services and physical environment, including the outdoor air and drinking water. The role of place, health disparities, and structural racism has been starkly displayed during the COVID-19 pandemic, where historically marginalized communities have been subject to greater rates of COVID-19 incidence and mortality.

Conclusion:

As COVID-19 becomes endemic, it is crucial to understand how place-based inequities and structural racism contributed to the COVID-19 racial disparities in incidence and mortality. Addressing structurally racist place-based health inequities through anti-racist policy strategies is one way to move the United States toward achieving health equity.

Physical Activity Intervention Adaptation: Recommendations from Rural American Indian Older Adults

Preventive interventions are critical to improving health equity among American Indian (AI) populations, yet interventions that promote physical activity (PA) among AI populations are scarce. This research addresses the research-to-practice gap by informing the adaption and implementation process of evidence-based interventions (EBIs) among rural AI older adults. We used a community-based approach and an Indigenous-focused adaptation theoretical framework. Qualitative, semi-structured interviews elicited detailed information on preferences for PA intervention among rural AI older adults. We applied a collaborative directed content analysis strategy, and established trustworthiness and relevance using an inter-rater reliability process and member checking. We conducted 21 interviews, all participants identified as AI, the mean age was 66 years (SD = 7.6), and 57% were female. Themes characterized contextual and cultural intervention considerations for adapting and implementing evidence-based PA interventions in rural AI older adults. Key findings included an emphasis on social and community interaction, strategies for targeted engagement, preference for group format, pairing PA sessions with shared meals, and inclusiveness in the PA intervention across ability levels and age groups. This study identified opportunities for adaptation of PA-focused EBIs among rural AI older adults. Findings can be applied to support the adaptation and implementation of effective and relevant PA-focused preventive interventions among this population which is at high risk for chronic disease and health disparities.

Risk factors for hypertension and diabetes comorbidity in a Korean population: A cross-sectional study

BACKGROUND

Hypertension and diabetes are risk factors for severe cardiovascular disease and are prevalent comorbidities. No studies have examined the associations of various risk factors related to anthropometry, bone mineral density and body composition of specific body regions with hypertension and diabetes comorbidity (HDC). This study explored the association between HDC and various risk factors related to specific body regions.

METHOD

A total of 7,978 subjects (3,451 men and 4,527 women) aged ≥ 50 years were included in the analysis. A binary logistic regression analysis based on complex sample data analysis was conducted to examine associations between the normal and diabetes groups, between the normal and hypertension groups, and between the normal and HDC groups.

RESULTS

Among Korean adults aged ≥ 50 years, 11.27% of men and 10.05% of women had both diabetes and hypertension. The HDC prevalence was higher in men than in women. In men, waist-to-height ratio (WHtR, adjusted OR = 1.63 [1.22-2.18], adjusted p<0.001) exhibited a more significant association with HDC than other indices, left leg fat mass (adjusted OR = 0.61 [0.45-0.81], adjusted p = 0.0009) and right leg fat mass (adjusted OR = 0.60 [0.45-0.81], adjusted p = 0.0007) displayed strong negative associations with diabetes, and left leg lean mass (adjusted OR = 0.77 [0.67-0.89], adjusted p = 0.0002) and trunk fat mass (adjusted OR = 1.28 [1.07-1.52], adjusted p = 0.0062) were significantly associated with hypertension. In women, left leg fat mass (adjusted OR = 0.29 [0.22-0.39], adjusted p<0.0001) and right leg fat mass (adjusted OR = 0.32 [0.23-0.45], adjusted p<0.0001) exhibited strong negative associations with HDC, waist circumference (WC) (adjusted OR = 2.15 [1.40-3.30], adjusted p = 0.0005) showed a stronger association with diabetes than did other indices, and WC (adjusted OR = 1.39 [1.11-1.74], adjusted p = 0.0040) and WHtR (adjusted OR = 1.39 [1.09-1.76], adjusted p = 0.0075) were significantly associated with hypertension.

DISCUSSION

HDC was more strongly associated with fat and lean mass than diabetes and hypertension. The association between HDC and body fat variables was more robust in women than in men.

Uplifting the voices of rural American Indian older adults to improve understanding of physical activity behavior

American Indian (AI) older adults experience pronounced health disparities and demonstrate one of the lowest levels of physical activity (PA) among racial and ethnic groups. Nearly half of AI older adults live in rural areas, indicating distinct challenges to participation in PA. Research to identify factors influencing PA in this population is missing from the literature, yet is critical to informing culturally relevant PA intervention development and implementation. The purpose was to identify barriers to and facilitators of PA among rural AI older adults using the ecological model and qualitative methods. A community-based approach was used to conduct semi-structured interviews with rural AI older adults. Interview questions were based on a multi-level ecological model. Content analysis was performed, using an iterative coding process to identify findings. The mean age of participants (n = 21) was 66 years. Barriers to and facilitators of PA were identified across ecological model levels. Barriers included factors such as caregiving and community responsibilities, lack of acceptable areas for walking, and overall lack of community-level support for older adult health. Facilitators included a personal connection to the land and ancestors through PA, multigenerational participation, and supportive tribal policies. This study addressed a gap in the literature by identifying barriers to and facilitators of PA among rural AI older adults, which can inform PA intervention development. With barriers and facilitators identified by AI older adults themselves, the voices of those directly affected are uplifted to shape efforts toward addressing longstanding health disparities through relevant public health interventions.

Health Care Access and Utilization for American Indian Elders: A Concept-Mapping Study

OBJECTIVES

Inequities in access to and utilization of health care greatly influence the health and quality of life of American Indian elders (AIEs). This study explores the importance and perceived prevalence of factors affecting health care use within this population and assesses the changeability of these factors to produce a list of action items that are timely and relevant to improving health care access and utilization.

METHOD

Concept mapping was conducted with AIEs (n = 65) and professional stakeholders (n = 50), including tribal leaders, administrators of public-sector health systems, outreach workers, and health care providers. Data were analyzed using multidimensional scaling and cluster analyses.

RESULTS

The final concept-map model comprised nine thematic clusters related to factors affecting elder health care: Difficulties Obtaining and Using Insurance; Insecurity from Lack of Knowledge; Limited Availability of Services; Scheduling Challenges; Provider Issues and Relationships; Family and Emotional Challenges; Health-Related Self-Efficacy and Knowledge; Accessibility and Transportation Barriers; and Tribal/National Policy.

DISCUSSION

Findings suggest that improvements in access to and utilization of health care among AIEs will require actions across multiple domains, including health system navigation services, workforce improvements, and tribal, state, and federal policy. A multilevel socioecological approach is necessary to organize and undertake these actions.

American Indian Alcohol Use from a Sex-Specific Wellness Approach: Exploring Its Associated Physical, Behavioral, and Mental Risk and Protective Factors

PURPOSE

The top causes of death for American Indians (AIs), including heart and liver disease, are associated with alcohol use. Using the culturally based Framework of Historical Oppression, Resilience, and Transcendence (FHORT), the purpose of this article was to examine AI alcohol use from a sex-specific wellness approach, exploring its associated physical, behavioral, and mental risk and protective factors.

METHOD

Data were drawn from a cross-sectional survey with 479 AI adults in South Dakota. We employed a series of multiple hierarchical regression analyses to assess the associations of demographic (sex, age, marital status, income, and educational attainment), physical (Body Mass Index and cardiovascular risk), behavioral (smoking and health self-efficacy) and mental (depressive symptoms) factors with alcohol use.

RESULTS

Results indicated that surveyed males tended to drink three times that of females, and depressive symptoms were associated with higher levels of alcohol use.

DISCUSSION

This study highlights the need to examine AI alcohol use with sex in mind.

The Bidirectional Association Between Physical and Cognitive Function Among Chinese Older Adults: A Mediation Analysis

This study investigated the bidirectional association between physical and cognitive function in later life and examined the mechanisms underlying the interrelationship. We employed cross-lagged panel models to analyze a sample of 4232 unique participants aged 65 years and older from three waves of the Chinese Longitudinal Healthy Longevity Survey. Physical activity and social participation were tested as potential mediators between physical and cognitive function. Our findings revealed a reciprocal relationship between physical and cognitive function and a reciprocal relationship between physical and cognitive decline. Moreover, physical activity was confirmed to mediate the bidirectional association between physical and cognitive function, whereas social participation did not seem to be a mediator. A vicious cycle linking physical and cognitive decline may exist in Chinese older adults. However, leading a physically active lifestyle could be an effective intervention to slow physical and cognitive aging, thereby toning down the vicious cycle.

Cardiovascular Health among U.S. Indigenous Peoples: A Holistic and Sex-Specific Systematic Review

PURPOSE

The purpose of this systematic review is to examine mental, sociocultural, behavioral, and physical risk and protective factors related to cardiovascular disease (CVD) and related outcomes among U.S. Indigenous peoples.

METHODS

A total of 51 articles met the inclusion criteria of research focusing factors for CVD among U.S. Indigenous peoples (Mental n= 15; Sociocultural, n =17; Behavioral/Physical, n =19).

RESULTS

This review reveals clear risks for CVD, which tended to be elevated for females. Mental health problems (depression, anxiety, PTSD/trauma, alcohol and other drug (AOD) abuse) were clearly associated with CVD, along with enculturation, social support, and the social environment-including discrimination and trauma. Poor diet and obesity, diabetes, hypertension, cholesterol were behavioral or physical factors.

DISCUSSION

Overall, identified research was limited and in beginning stages, lacking more information on etiology of the interconnections across sex and the mental, sociocultural, and behavioral determinants of CVD.

Frailty in Older American Indians: The Native Elder Care Study

Introduction: Frailty is often described as a reduction in energy reserves, especially with respect to physical ability and endurance, and it has not been examined in American Indians. The goals of this study were to estimate the prevalence of frailty and identify its correlates in a sample of American Indians. Methods: We examined data from 411 community-dwelling American Indians aged ≥55 years. Frailty was measured with weight loss, exhaustion, low energy expenditure, slowness, and weakness characteristics. Results: Slightly over 44% of participants were classified as pre-frail and 2.9% as frail. Significant correlates of a combined pre-frail and frail status identified in the fully adjusted analyses were younger age, female gender, lower levels of education, increased number of chronic medical conditions, and increased number of activities of daily living limitations. Marital status, chronic pain, and social support were not associated with pre-frail/frail status. Conclusions: Our findings point to specific areas in need of further research, including use of frailty measures that also capture psychosocial components and examining constructs of physical resilience. Targeting those with multiple chronic medical conditions may be an important area in which to intervene, with the goal of reducing risk factors and preventing frailty onset.

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.

Social Determinants of Health Assessment Tool: Implications for Healthcare Practice

Underserved populations are at risk for chronic health conditions due to social determinants. There is a gap in instrument availability in identifying individuals at risk of, or experiencing, cumulative social, environmental, economic, and cultural factors impacting health. The Social Determinants of Health Assessment Tool is a brief, cost-effective semistructured interview allowing healthcare professionals to engage in appropriate service prioritization. Phase I of this instrument development reported adequate face validity by Delphi panel consensus with experts in social work, nursing, public health, and psychology. This instrument identifies individuals at risk of social determinants to improve healthcare and social service delivery.

"Improving Native American elder access to and use of health care through effective health system navigation"

BACKGROUND

Public insurance reforms of the past two decades have failed to substantively address the healthcare needs of American Indians in general, let alone the particular needs of American Indian elders, ages 55 years and older. Historically, this population is more likely to be uninsured and to suffer from greater morbidities, poorer health outcomes and quality of life, and lower life expectancies compared to all other United States aging populations, representing a neglected group within the healthcare system. Despite the pervasive belief that the Indian Health Service will address all their health-related needs, American Indian elders are negatively affected by gaps in insurance and lack of access to health care. While the 2010 Patient Protection and Affordable Care Act included provisions to ameliorate disparities for American Indians, its future is uncertain. In this context, American Indian elders with variable health literacy must navigate a complex and unstable healthcare system, regardless of where they seek care.

METHODS

This community-driven study features a mixed-method, participatory design to examine help-seeking behavior and healthcare experiences of American Indian elders in New Mexico, in order to develop and evaluate a tailored intervention to enhance knowledge of, access to, and use of insurance and available services to reduce healthcare disparities. This study includes qualitative and quantitative interviews combined with concept mapping and focus groups with American Indian elders and other key stakeholders.

DISCUSSION

The information gathered will generate new practical knowledge, grounded in actual perspectives of American Indian elders and other relevant stakeholders, to improve healthcare practices and policies for a population that has been largely excluded from national and state discussions of healthcare reform. Study data will inform development and evaluation of culturally tailored programming to enhance understanding and facilitate negotiation of the changing landscape of health care by American Indian elders. This work will fill a gap in research on public insurance initiatives, which do not typically focus on this population, and will offer a replicable model for enhancing the effects of such initiatives on other underserved groups affected by healthcare inequities.

Unmet Assistance Need Among Older American Indians: The Native Elder Care Study

PURPOSE

We examined the prevalence and correlates of unmet assistance need with respect to activities of daily living (ADLs) and instrumental activities of daily living (IADLs) among older American Indians.

DESIGN AND METHODS

Data for our analyses were collected in 2006-2008 as part of the Native Elder Care Study, a cross-sectional study of community-dwelling American Indians aged ≥55 years. In-person interviewer-administered surveys were used to collect data on demographic characteristics, physical functioning, mental and physical health, personal assistance needs, and psychosocial resources.

RESULTS

Among those with an assistance need, 47.8% reported an unmet need with one or more ADLs or IADLs. Significant adjusted correlates of unmet assistance need included greater number of ADL and IADL difficulties and lower levels of social support.

IMPLICATIONS

Initiatives and programs aimed at increasing social support and augmenting informal care networks can support efforts to meet American Indian adults' personal assistance needs.

Attitudes Toward Mental Health Services Among American Indians by Two Age Groups

This study examined determinants of attitudes toward mental health services with a sample of American Indian younger-old-adults (aged 50-64, n = 158) and American Indian older-old adults (aged 65 and older, n = 69). Adapting Andersen's behavioral model of healthcare utilization, predisposing factors, mental health needs, and enabling factors were considered as potential predictors. Female and those with higher levels of social support tend to report more positive attitudes toward mental health services. Culture-influenced personal belief was associated with negative attitudes toward mental health services among American Indian younger-old -adults. Age and higher chronic medical conditions were significantly related to negative attitudes toward mental health services. Health insurance was positively associated with positive attitudes toward mental health services in the American Indian older-old adults. Findings indicate that practitioners should engage how culture, social support, and chronic conditions influence the response to mental health needs when working with older American Indians.

Multimorbidity and functional decline in community-dwelling adults: a systematic review

BACKGROUND

Multimorbidity affects up to one quarter of primary care populations. It is associated with reduced quality of life, an increased risk of mental health difficulties and increased healthcare utilisation. Functional decline is defined as developing difficulties with activities of daily living and is independently associated with poorer health outcomes. The aim of this systematic review was to examine the association between multimorbidity and functional decline and to what extent multimorbidity predicts future functional decline.

METHODS

A systematic literature search (1990-2014) and narrative analysis was conducted.

INCLUSION CRITERIA

Population; Community-dwelling adults (≥18 years), Risk; Multimorbidity defined as the presence of ≥2 chronic medical conditions in an individual, Primary outcome; Physical functional decline measured using a validated instrument, Study design; cross-sectional or cohort studies. The following databases were included: PubMed, EMBASE, CINAHL, the Cochrane Library and the International Research Community on Multimorbidity (IRCMo) publication list. Methodological quality assessment of included studies was conducted with a suitable risk of bias tool.

RESULTS

A total of 37 studies were eligible for inclusion (28 cross-sectional studies and 9 cohort studies). The majority of cross-sectional studies (n = 24/28) demonstrated a consistent association between multimorbidity and functional decline. Twelve of these studies reported that increasing numbers of chronic condition counts were associated with worsening functional decline. Nine cohort studies included 14,133 study participants with follow-up periods ranging from one to six years. The majority (n = 5) found that multimorbidity predicted functional decline. Of the five studies that reported the impact of increasing numbers of conditions, all reported greater functional decline with increasing numbers of conditions. One study examined disease severity and found that this also predicted greater functional decline. Overall, cohort studies were of good methodological quality but were mixed in terms of participants, multimorbidity definitions, follow-up duration, and outcome measures.

CONCLUSIONS

The available evidence indicates that multimorbidity predicts future functional decline, with greater decline in patients with higher numbers of conditions and greater disease severity. This review highlights the importance of considering physical functioning when designing interventions and systems of care for patients with multimorbidity, particularly for patients with higher numbers of conditions and greater disease severity.

Risk and protective factors for depressive symptoms among American Indian older adults: adverse childhood experiences and social support

OBJECTIVES

Despite efforts to promote health equity, many American Indian and Alaska Native (AI/AN) populations, including older adults, experience elevated levels of depression. Although adverse childhood experiences (ACE) and social support are well-documented risk and protective factors for depression in the general population, little is known about AI/AN populations, especially older adults. The purpose of this study was to examine factors related to depression among a sample of AI older adults in the midwest.

METHOD

Data were collected using a self-administered survey completed by 233 AIs over the age of 50. The survey included standardized measures such as the Geriatric Depression Scale-Short Form, ACE Questionnaire, and the Multidimensional Scale of Perceived Social Support. Hierarchical multivariate regression analyses were conducted to evaluate the main hypotheses of the study.

RESULTS

Two dimensions of ACE (i.e., childhood neglect, household dysfunction) were positively associated with depressive symptoms; social support was negatively associated with depressive symptoms. Perceived health and living alone were also significant predictors.

CONCLUSION

ACE may play a significant role in depression among AI/AN across the life course and into old age. Social support offers a promising mechanism to bolster resilience among AI/AN older adults.

Stressors, Coping Resources, and Depressive Symptoms among Rural American Indian Older Adults

The purpose of this study was to examine the associations of physical health stressors and coping resources with depressive symptoms among American Indian older adults age 50 years or older. The study used a convenience sample of 227 rural American Indian older adults. A hierarchical multiple regression tested three sets of predictors on depressive symptoms: (a) sociodemographics, (b) physical health stressors (functional disability and chronic medical conditions), and (c) coping resources (social support and spirituality). Most participants reported little difficulty in performing daily activities (e.g., eating, dressing, traveling, and managing money), while presenting over two types of chronic medical conditions. Depressive symptoms were predicted by higher scores on perceived social support and lower scores on functional disability; women and those having no health insurance also had higher levels of depressive symptoms. Findings suggest that social work practitioners should engage family and community support, advocate for access to adequate health care, and attend to women's unique circumstances and needs when working with American Indian older adults.

Predicting Help-Seeking Attitudes Toward Mental Health Services Among American Indian Older Adults: Is Andersen's Behavioral Model a Good Fit?

American Indian (AI) older adults are vulnerable to mental health disparities, yet very little is known about the factors associated with help-seeking for mental health services among them. The purpose of this study was to investigate the utility of Andersen's Behavioral Model in explaining AI older adults' help-seeking attitudes toward professional mental health services. Hierarchical regression analysis was used to examine predisposing, enabling, and need variables as predictors of help-seeking attitudes toward mental health services in a sample of 233 AI older adults from the Midwest. The model was found to have limited utility in the context of older AI help-seeking attitudes, as the proportion of explained variance was low. Gender, perceived stigma, social support, and physical health were significant predictors, whereas age, perceived mental health, and health insurance were not.

Social engagement and physical and cognitive health among American Indian participants in the health and retirement study

Social engagement has many demonstrated benefits for aging non-Hispanic Whites in the U.S. This study examined data from the U.S. Health and Retirement Study to determine whether these benefits were similar among American Indians and Alaska Natives older than 50 years. Linear regression techniques were used to examine the associations between level of social engagement, scores for memory and mental status, and self-reported health among 203 American Indian and Alaska Native elders who participated in the Health and Retirement Study and had data available between 1998 and 2010. Level of social engagement was significantly associated with memory, mental status, and self-reported health. However, only the association of social engagement with mental status and self-reported health remained significant (p = 0.04 and p = 0.05, respectively) after adjusting for sociodemographic variables, number of known health conditions, and scores on the Center for Epidemiologic Studies Depression scale. Level of social engagement was not associated with patterns of decline across time in cognitive or physical health. Higher levels of social engagement are associated with better physical and cognitive functioning in American Indian and Alaska Native elders. Future studies should examine whether this association acts through cognitive stimulation, increase in physical activity resulting from social engagement, or access to resources that support physical and cognitive health.

Poor Survival for American Indians with Head and Neck Squamous Cell Carcinoma

OBJECTIVE

To examine patient characteristics, treatment modalities, and human papillomavirus (HPV) prevalence to identify potential mediators of disparities that may lead to differences in outcomes for American Indians with head and neck squamous cell carcinoma (HNSCC).

STUDY DESIGN

Historical cohort study.

SETTING

Community cancer centers.

PATIENTS AND METHODS

We reviewed all patients older than 18 years with a new diagnosis of HNSCC in South Dakota from 1999 to 2009. We assessed tissue samples from cases of oropharyngeal cancer for the presence of HPV DNA.

RESULTS

In total, 474 white patients were compared with 32 American Indians. American Indians experienced significantly worse survival compared with whites (hazard ratio [HR], 0.59; P = .05), even after controlling for other factors such as age, sex, distance, Charlson comorbidity index, alcohol abuse, smoking, insurance, and disease stage. American Indians had a greater risk of alcohol abuse (68% vs 42%; P = .008), current smoking (67% vs 49%; P = .03), living more than 1 hour from a cancer center (81% vs 30%; P < .001), lacking private insurance (24% vs 68%; P < .001), and late-stage disease presentation (stages III and IV) (74% vs 55%; P = .04). There were no detected differences in age, sex, medical comorbidities, tumor site, tumor grade, HPV status, time to treatment, or type of treatment received.

CONCLUSION

American Indians in South Dakota with HNSCC have poorer survival compared with white patients. Once presented to a cancer center, American Indians received nearly identical treatment to white patients. Disparities in outcomes arise primarily due to sociodemographic factors and later stage at presentation.

The association of resilience with mental and physical health among older American Indians: the Native Elder Care Study

We examined the association of resilience with measures of mental and physical health in a sample of older American Indians (AIs). A validated scale measuring resilience was administered to 185 noninstitutionalized AIs aged>=55 years. Unadjusted analyses revealed that higher levels of resilience were associated with lower levels of depressive symptomatology and chronic pain, and with higher levels of mental and physical health. Resilience remained significantly associated with depressive symptomatology after controlling for demographic and other health measures. Our findings suggest that resilience among older AIs has important implications for some aspects of mental and physical health.

Disparities in health status and health care access and use among older American Indians and Alaska Natives and non-Hispanic Whites in California

OBJECTIVES

The present study compared the characteristics of health status and health care access and use among older American Indians and Alaska Natives (AIANs) to those of non-Hispanic Whites (NHWs).

METHODS

Data were drawn from the 2009 California Health Interview Survey, with a total of 17,156 adults aged 60 and older (198 AIANs and 16,958 NHWs) analyzed.

RESULTS

Older AIANs reported poorer physical and mental health than did NHWs. AIANs were less likely than NHWs to see a medical doctor and have a usual source of medical care and were more likely than NHWs to delay getting needed medical care and report difficulty understanding the doctor at their last visit.

DISCUSSION

These findings highlight the vulnerability and unmet health care needs of older AIANs. More research on the older AIAN population is clearly needed to document their health care needs in order to better inform efforts to reduce health disparities.

Lower body functioning prevalence and correlates in older American Indians in a southeastern tribe: the Native Elder Care Study

The objective of this study was to use performance-based measurements to identify, in a population of community-dwelling American Indians aged 55 and older, the prevalence and correlates of lower body functioning. Data were collected as part of a cross-sectional study of disability from members of a tribe in the southeast. Lower body functioning was measured using the Short Physical Performance Battery (SPPB), where higher scores reflect better functioning. Independent variables included age, sex, marital status, educational attainment, current cigarette smoking, physical activity, body mass index (BMI), hearing loss, vision loss, bone or joint trauma, chronic pain syndrome, osteoporosis, medical comorbidity, and depressive symptomatology. The total composite SPPB score (8.8 ± 3.4) declined significantly with increasing age and was negatively associated with unmarried status, physical inactivity, vision loss, bone or joint trauma, and medical comorbidity after adjustment for all other factors in the model. Likewise, all individual SPPB component scores declined significantly with increasing age and were negatively associated with physical inactivity and comorbidity. The balance test score was significantly and negatively associated with unmarried status and vision loss; gait speed was negatively related to unmarried status; and chair stand test score was negatively related to BMI, vision loss, bone or joint trauma, and chronic pain syndrome. In the clinical setting, the SPPB can be an important screening tool for adverse health-related events. Further studies are needed to investigate the determinants and sequelae of physical dysfunction in this population.

Insomnia symptoms and cardiovascular disease among older American Indians: the Native Elder Care Study

Background. Cardiovascular disease (CVD) is the leading cause of death among American Indians. It is not known if symptoms of insomnia are associated with CVD in this population. Methods. We examined 449 American Indians aged ≥55 years from the Native Elder Care Study. The main outcome-of-interest was self-reported CVD. Results. Short sleep duration, daytime sleepiness, and difficulty falling asleep were positively associated with CVD after adjusting for demographic, lifestyle, and clinical risk factors. Compared with a sleep duration of 7 h, the multivariable odds ratio (OR) (95% confidence interval [CI]) of CVD among those with sleep duration ≤5 h was 2.89 (1.17–7.16). Similarly, the multivariable OR (95% CI) of CVD was 4.45 (1.85–10.72) and 2.60 (1.25–5.42) for daytime sleepiness >2 h and difficulty falling asleep often/always. Conclusion. Symptoms of insomnia including short sleep duration, daytime sleepiness, and difficulty falling asleep are independently associated with CVD in American Indians aged ≥55 years.
