Emerging Opportunities for Registered Dietitian Nutritionists to Help Raise a Healthier Generation of Native American Youth

Reliability and Validity of Diabetes Nutrition Self-Efficacy and Behavior Measures for the "What Can I Eat" Diabetes Nutrition Education Program for American Indian and Alaska Native Adults With Type 2 Diabetes

BACKGROUND

American Indian and Alaska Native (AI/AN) people have high rates of diabetes and limited access to nutrition education. The "What Can I Eat? Healthy Choices for People With Type 2 Diabetes" (WCIE) diabetes nutrition education program was culturally adapted for AI/AN adults.

OBJECTIVE

This analysis was designed to evaluate the reliability and validity of items developed to measure diabetes nutrition self-efficacy (ie, confidence one can engage in specific behaviors) and diabetes nutrition behavior among participants in the WCIE program for AI/AN adults.

DESIGN

This study was a secondary analysis of data from a randomized controlled trial designed to evaluate the WCIE program for AI/AN adults. Baseline data were used to assess the reliability and validity of the self-efficacy and behavior items, which were collected via survey. Due to COVID-19 safety protocols, the intervention was conducted via Zoom (Zoom Video Communications), and both survey and clinical data were collected at home by participants.

PARTICIPANTS/SETTING

The study was conducted from January to December 2021 with 5 AI/AN-serving health care programs in Oklahoma, Illinois, North Carolina, California, and New York. AI/AN adults with type 2 diabetes who spoke English and had internet access were eligible. Sixty people participated.

MAIN OUTCOME MEASURES

Analyses examined validity and reliability of diabetes nutrition self-efficacy and behavior items.

STATISTICAL ANALYSIS PERFORMED

To test reliability, internal consistency and factor structures of the scales were examined. To evaluate convergent validity, Pearson correlations were computed to examine the association of the self-efficacy and behavior measures with each other and with clinical indicators (ie, body mass index, blood pressure, and hemoglobin A1c).

RESULTS

Two self-efficacy factors were identified. Each showed strong internal consistency (Cronbach α ≥ 0.85; McDonald ω ≥ 0.88) and was directly associated with diabetes nutrition behavior (P < .001). The factor assessing Confidence in Using the Diabetes Plate was inversely associated with hemoglobin A1c (Pearson correlation = -0.32, P = .0243). The behavior measure capturing Healthy Nutrition Behavior showed strong internal consistency (α = 0.89; ω = 0.92) and was inversely associated with hemoglobin A1c (Pearson correlation = -0.38, P = .0057).

CONCLUSIONS

Diabetes nutrition self-efficacy and behavior items developed for the WCIE program for AI/AN adults are valid and reliable. These items can facilitate rigorous and consistent evaluation of the AI/AN WCIE program.

Diabetes Prevention and Care Capacity at Urban Indian Health Organizations

American Indian and Alaska Native (AI/AN) people suffer a disproportionate burden of diabetes and cardiovascular disease. Urban Indian Health Organizations (UIHOs) are an important source of diabetes services for urban AI/AN people. Two evidence-based interventions-diabetes prevention (DP) and healthy heart (HH)-have been implemented and evaluated primarily in rural, reservation settings. This work examines the capacity, challenges and strengths of UIHOs in implementing diabetes programs. Methods: We applied an original survey, supplemented with publicly-available data, to assess eight organizational capacity domains, strengths and challenges of UIHOs with respect to diabetes prevention and care. We summarized and compared (Fisher's and Kruskal-Wallis exact tests) items in each organizational capacity domain for DP and HH implementers vs. non-implementers and conducted a thematic analysis of strengths and challenges. Results: Of the 33 UIHOs providing services in 2017, individuals from 30 sites (91% of UIHOs) replied to the survey. Eight UIHOs (27%) had participated in either DP (n = 6) or HH (n = 2). Implementers reported having more staff than non-implementers (117.0 vs. 53.5; p = 0.02). Implementers had larger budgets, ~$10 million of total revenue compared to $2.5 million for non-implementers (p = 0.01). UIHO strengths included: physical infrastructure, dedicated leadership and staff, and community relationships. Areas to strengthen included: staff training and retention, ensuring sufficient and consistent funding, and data infrastructure. Conclusions: Strengthening UIHOs across organizational capacity domains will be important for implementing evidence-based diabetes interventions, increasing their uptake, and sustaining these interventions for AI/AN people living in urban areas of the U.S.

Exposure to a Multilevel, Multicomponent Obesity Prevention Intervention (OPREVENT2) in Rural Native American Communities: Variability and Association with Change in Diet Quality

The OPREVENT2 obesity prevention trial was a multilevel multicomponent (MLMC) intervention implemented in rural Native American communities in the Midwest and Southwest U.S. Intervention components were delivered through local food stores, worksites, schools, community action coalitions, and by social and community media. Due to the complex nature of MLMC intervention trials, it is useful to assess participants’ exposure to each component of the intervention in order to assess impact. In this paper, we present a detailed methodology for evaluating participant exposure to MLMC intervention, and we explore how exposure to the OPREVENT2 trial impacted participant diet quality. There were no significant differences in total exposure score by age group, sex, or geographic region, but exposure to sub-components of the intervention differed significantly by age group, sex, and geographical region. Participants with the highest overall exposure scores showed significantly more improvement in diet quality from baseline to follow up compared to those who were least exposed to the intervention. Improved diet quality was also significantly positively associated with several exposure sub-components. While evaluating exposure to an entire MLMC intervention is complex and imperfect, it can provide useful insight into an intervention’s impact on key outcome measures, and it can help identify which components of the intervention were most effective.

An online diabetes nutrition education programme for American Indian and Alaska Native adults with type 2 diabetes: perspectives from key stakeholders

OBJECTIVE

To explore stakeholder perspectives regarding online diabetes nutrition education for American Indians and Alaska Natives (AI/AN) with type 2 diabetes (T2D).

DESIGN

Qualitative data were collected through focus groups and interviews. Focus group participants completed a brief demographic and internet use survey.

SETTING

Focus groups and community participant interviews were conducted in diverse AI/AN communities. Interviews with nationally recognised content experts were held via teleconference.

PARTICIPANTS

Eight focus groups were conducted with AI/AN adults with T2D (n 29) and their family members (n 22). Community participant interviews were conducted with eleven clinicians and healthcare administrators working in Native communities. Interviews with nine content experts included clinicians and researchers serving AI/AN.

RESULTS

Qualitative content analysis used constant comparative method for coding and generating themes across transcripts. Descriptive statistics were computed from surveys. AI/AN adults access the internet primarily through smartphones, use the internet for many purposes and identify opportunities for online diabetes nutrition education.

CONCLUSIONS

Online diabetes nutrition education may be feasible in Indian Country. These findings will inform the development of an eLearning diabetes nutrition education programme for AI/AN adults with T2D.

Diet Quality of Pregnant American Indian Women in the Northern Plains

INTRODUCTION

We examined diet quality and intake of pregnancy-specific micronutrients among pregnant American Indian women in the Northern Plains.

METHODS

We conducted an analysis of nutrition data from the Prenatal Alcohol and SIDS and Stillbirth (PASS) Network Safe Passage Study and the PASS Diet Screener study (N = 170). Diet intake, including dietary supplementation, was assessed by using three 24-hour recalls conducted on randomly selected, nonconsecutive days. Diet intake data were averaged across the participant's recalls and scored for 2 dietary indices: the Healthy Eating Index 2010 (HEI-2010) and the Alternate Healthy Eating Index for Pregnancy (AHEI-P). We also assessed nutrient adequacy with Dietary Reference Intakes for pregnancy.

RESULTS

On average, participants were aged 26.9 (standard deviation [SD], 5.5) years with a pre-pregnancy body mass index of 29.8 (SD, 7.5) kg/m². Mean AHEI-P and HEI-2010 scores (52.0 [SD, 9.0] and 49.2 [SD, 11.1], respectively) indicated inadequate adherence to dietary recommendations. Micronutrient intake for vitamins D and K, choline, calcium, and potassium were lower than recommended, and sodium intake was higher than recommended.

CONCLUSION

Our findings that pregnant American Indian women are not adhering to dietary recommendations is consistent with studies in other US populations. Identifying opportunities to partner with American Indian communities is necessary to ensure effective and sustainable interventions to promote access to and consumption of foods and beverages that support the adherence to recommended dietary guidelines during pregnancy.

Grandmother and health care professional breastfeeding perspectives provide opportunities for health promotion in an American Indian community

RATIONALE

While breastfeeding is well recognized as beneficial, rates of breastfeeding among American Indian women are below average and contribute to health inequities. Culturally specific approaches to breastfeeding research are called for to inform appropriate interventions in American Indian communities. Specifically, a grandmother's role in breastfeeding promotion is of great import particularly in American Indian (AI) groups, although is an understudied topic to date.

OBJECTIVE

This research seeks to fill a prominent literature gap by utilizing a grounded theory and community-based research approach to inform breastfeeding practices from the voices of grandmothers and health care professionals in a rural AI community in the United States.

METHODS

A community-based approach guided the research process. Convenience and snowball sampling was used to recruit for semi-structured and follow up member checking interviews with AI grandmothers (n = 27) and health care professionals (n = 7). Qualitative data were transcribed, characterized into meaning units, and coded by a review panel. Data were reconciled for discrepancies among reviewers, organized thematically, and used to generate community-specific breastfeeding constructs.

RESULTS

Three major themes emerged, each with relevant subthemes: (1) importance of breastfeeding; (2) attachment, bonding, and passing on knowledge; and (3) overburdened health care system. Multiple subthemes represent stressors and impact breastfeeding knowledge, translation, and practice within this community including formula beliefs, historical traumas, societal pressures, mistrust, and substance abuse.

CONCLUSIONS

Interventions designed to raise breastfeeding rates in the study site community would ideally be grounded in tribal resources and involve a collaborative approach that engages the greater community, grandmothers, health care professionals, and scientific partners with varying skills. More research is needed to determine stressors and any potential impact on infant feeding practices among other AI groups. Application of the research approach presented here to other AI communities may be beneficial for understanding opportunities and challenges to breastfeeding practices.
