Physical Activity Intervention Adaptation: Recommendations from Rural American Indian Older Adults.
Prevention science : the official journal of the Society for Prevention Research
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 66years (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.

Uplifting the voices of rural American Indian older adults to improve understanding of physical activity behavior.
Translational behavioral medicine
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.

A Systematic Review of Interventions to Increase Physical Activity Among American Indian and Alaska Native Older Adults.
Physical activity (PA) is a powerful protective factor known to reduce risk for chronic conditions across the lifespan. 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.The systematic review was designed in accordance with the PRISMA statement for systematic review protocols and reporting guidelines. Electronic databases PubMed, Web of Science, and PsycINFO were searched for academic literature. Trials investigating interventions to increase PA among AIAN adults ages 50+ were eligible. The Quality Assessment Tool for Quantitative Studies was used to evaluate the quality of evidence.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 a community-engaged or culture-centered research strategies.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 lifespan.

Building Capacity to Increase Health Promotion Funding to American Indian Communities: Recommendations From Community Members
HEALTH PROMOTION PRACTICE
2016; 17 (6): 907-914
Foundations and government agencies have historically played a critical role in supporting community-based health promotion programs. Increased access to health promotion funding may help address significant health issues existing within American Indian (AI) communities, such as childhood obesity, type 2 diabetes, and cardiovascular disease. Understanding the capacity of AI communities to successfully apply for and receive funding may serve to increase resources for health promotion efforts within AI communities in Montana. This exploratory qualitative study completed 17 semistructured interviews across three AI reservations in the state of Montana. Dimensions of community capacity within the context of the funding application process and partnership with funding agencies were identified, including resources, leadership, community need, networks, and relationship with the funding agency. Dimensions of AI community capacity were then used to suggest capacity-building strategies for improved partnership between AI communities in Montana and the funding agencies.

Group Gardening in a Native American Community: A Collaborative Approach.
Health promotion practice
2020; 21 (4): 611-623
Background. There is increasing awareness of the potential health benefits derived from gardening activities. Gardening practices are gaining momentum in Native American (NA) communities, yet no efforts have applied a community-based participatory research approach within a social-ecological model to understand opportunities and barriers for group gardening on an American Indian reservation. Objectives. The primary objective of this study was to identify influences across social-ecological levels that promote or hinder the implementation of community gardens and use of locally grown foods on the reservation; a secondary objective was to assess the feasibility of implementing a group gardening program for NA adults and potential of collecting health outcome measures. Method. Community members and academicians collaborated to develop and implement this study. The study (1) conducted interviews with key stakeholders to identify influences across social-ecological levels that promote or hinder the implementation of community gardens and using locally produced food and (2) assessed the physical and psychological well-being of NA adults participating in a group gardening feasibility study. Results. Major factors influencing using locally grown food and community gardens that emerged from nine interviews included knowledge/experience, self-efficacy, Elders, traditional ways, community values, generational gaps, and local tribal policies. Twenty NA adults with prediabetes or diabetes participated in the feasibility study. The Profile of Mood States Inventory showed consistently positive change in score for participants in the group gardening program versus the comparison group. Conclusions. This study identified key influences for growing locally grown food, and approaches for implementing group gardening programs for NA adults.

Community Readiness Model for Prevention Planning: Addressing Childhood Obesity in American Indian Reservation Communities
JOURNAL OF RACIAL AND ETHNIC HEALTH DISPARITIES
2019; 6 (6): 1144-1156
The community readiness model (CRM) is a stage-matched assessment protocol to assess community readiness to address a public health issue. To identify appropriate, culturally sensitive, and community-specific intervention strategies for preventing obesity in children, researchers, and community members formed a partnership to address childhood obesity within one American Indian Reservation.The CRM guided 30 interviews in five communities to direct the team's efforts in addressing obesity among children residing on the reservation. Interviews were scored across six dimensions on an anchored scale of one through nine; scores were then averaged to determine an overall readiness score for each community. A thematic analysis of interview responses aided in interpretation of the readiness scores and identified areas for prevention planning and intervention development.The overall community readiness score for the communities was 2.9 (SD = 0.5), which falls between 2 (denial/resistance) and 3 (vague awareness) on the anchored rating scale. The thematic analysis resulted in a hierarchal classification scheme with six broad themes that corresponded to the CRM dimensions and 13 sub-themes.The low readiness scores directed the team to implement corresponding strategies to increase awareness, while the thematic analysis suggested that action-based approaches might also be appropriate. The narrow range of scores suggest that community-wide assessments may be sufficient unless specific information is needed for each region of the community. The CRM may be an effective way to assess community readiness to address childhood obesity on an American Indian Reservation.

The safety of tai chi: A meta-analysis of adverse events in randomized controlled trials
CONTEMPORARY CLINICAL TRIALS
2019; 82: 85-92
To review current publications to examine safety of tai chi (TC).Cochrane Library, EBSCO host and MEDLINE/PubMed were searched for randomized controlled trials (RCTs) including TC as the core intervention and reporting adverse events (AEs). Data were extracted considering active vs. inactive control group comparisons and presence of an AE monitoring protocol. Meta-analyses were conducted for overall results as well as control group and reporting specific conditions.In 256 RCTs of TC, 24 met eligibility criteria (1794 participants) and were assessed using the Cochrane Risk of Bias tool. The frequency of non-serious, serious and intervention-related AEs were not found to be significantly different between TC and inactive or active control conditions. In studies with an AE monitoring protocol, more non-serious adverse events (RD = 0.05; 95% CI: 0.00, 0.10; P = 0.05) were reported for TC compared to inactive interventions. Given the higher overall AE risks related to studies of participants with heart failure, additional analyses examined this set separately. More serious AEs were found for inactive interventions compared with TC in studies with heart failure participants (RD = -0.11; 95% CI: -0.20, -0.03; P = 0.01).Findings indicate that TC does not result in more AEs than active and inactive control conditions, and produces fewer AEs than inactive control conditions for heart failure patients.

Rural Parent Support of Child Health Behavior in the Home Environment: A Qualitative Study on an American Indian Reservation.
Global pediatric health
2019; 6: 2333794X19847451
Background. Obesity rates are disproportionately high among rural and American Indian (AI) children. Health behaviors contributing to child obesity are influenced by parents at home. Engaging parents remains a challenge, particularly among low-income and ethnic minority families. Aims. The aim of this study was to learn how AI parents living on a rural AI reservation support and engage with their children's nutrition and physical activity behaviors at home. Methods. Parents with children ages 6 to 12 years living on one, rural AI reservation participated. Focus groups and interviews were conducted, using a 14-question moderator's guide. A systematic, iterative content analysis was applied to the transcripts. Results. Twenty-five parents (52% AI or Alaska Native) participated in 3 focus groups (n = 17) and interviews (n = 8). Themes related to enhancers included role modeling and whole family and child-initiated activities. Barriers included resources, child safety concerns, driving distances, and competing family priorities. Themes related to strategies for change included opportunities for peer learning from other local families, creating fun, program support for all supplies and incentives, and incorporation of storytelling and multicultural activities. Discussion. This study advances knowledge to promote parental engagement with child health behavior in the home, including unique themes of inclusiveness, culture-focused, and intergenerational activities. Conclusion. Results may inform interventions seeking to engage parents living in rural and AI reservation communities in home-based child behavior change efforts.

Qigong/Tai Chi Easy for fatigue in breast cancer survivors: Rationale and design of a randomized clinical trial
CONTEMPORARY CLINICAL TRIALS
2016; 50: 222-228
Breast cancer survivors (BCSs) often report fatigue that persists for years following treatment. Despite a growing body of evidence for meditative movement practices to improve symptoms among BCSs, few studies have explored using Qigong/Tai Chi to reduce fatigue. Additionally, few have examined the biological mechanisms through which fatigue may be reduced using Qigong/Tai Chi.We will recruit 250 fatigued, post-menopausal women diagnosed with breast cancer (stage 0-III), between 6months and 5years past primary treatment and randomize to a standardized Qigong/Tai Chi Easy (QG/TCE) intervention, a "sham" Qigong group (movements without a focus on the breath and meditative state) (SQG), or an educational support (ES) group. The primary outcome (fatigue), secondary outcomes (anxiety, depression, sleep quality, cognitive function, physical activity), and a biomarker of HPA axis dysregulation (diurnal cortisol) will be assessed at baseline, post-intervention and 6months postintervention, and biomarkers of inflammation (IL1ra, IL6, TNFα and INFᵧ) at pre/post-intervention. We hypothesize that QG/TCE will reduce fatigue (and improve other symptoms associated with fatigue) in BCSs experiencing persistent cancer-related fatigue more than SQG and ES. Biomarkers will be examined for relationships to changes in fatigue.Findings from this study may reveal the effects of the unique mind-body aspects of QG/TCE on fatigue in BCSs with a complex design that separates the effects of low-intensity physical activity (SQG) and social support/attention (ES) from the primary intervention. Further, results will likely contribute greater understanding of the biological mechanisms of these practices related to improved symptoms among BCSs.
