The cost-efficacy of a healthy food box for managing hypertension within a native American population: a group randomized controlled trial.

BACKGROUND: Dietary interventions are used for the treatment of hypertension. We evaluated the cost-efficacy of delivering boxes of healthy, culturally tailored foods and checks that can only be spent on produce in a Native American population. METHODS: We conducted a group randomized controlled trial from 2018 to 2020 with N = 2 treatment counties and N = 2 control counties and a total of N = 160 Native American adults with baseline stage 1 or stage 2 hypertension. Participants in the intervention group received monthly boxes of food that adheres to the Dietary Approaches to Stop Hypertension diet as well as checks that could only be spent on produce for 6 months. We measured blood pressure and quality of life at baseline and at a 6-month follow-up in both intervention and control groups. We used ordered logistic regression to estimate the effect of treatment on probability of blood pressure improvements. We then conducted a cost-efficacy analysis. RESULTS: We found that treatment was effective in reducing blood pressure in women with stage 1 hypertension at baseline. Based on this finding, we also estimate that this intervention satisfies normative cost-effectiveness thresholds, even when lifetime treatment is needed to preserve the impact, so long as treatment is only continued in those who respond to treatment. CONCLUSIONS: Direct delivery of healthy foods and checks that can only be spent on produce are a potentially cost-effective intervention for the management of hypertension among Native American women with stage 1 hypertension. Further research is needed to understand why we found an impact only for this group.

Framing an Indigenous Food Sovereignty Research Agenda.

Access to healthy and appealing food is essential for individuals to be able to live a healthy and quality life. For decades, food security has been a priority issue for public health professionals. Food sovereignty expands upon the concept of food insecurity (i.e., having access to nutritious and culturally relevant food) by incorporating people's rights to define their own food system. The expanded focus of food sovereignty on food systems prioritizes public health professionals' role in supporting environmental- and systems-level initiatives and evaluating their implications for health, economics, and the natural environment. Food sovereignty is of particular importance for Indigenous peoples (i.e., American Indian, Alaska Native, Native Hawaiian, and Pacific Islander communities). Colonization had demonstrable consequences, with many Indigenous communities being forcibly relocated from traditional lands, alongside the destruction of traditional food sources. Indigenous food sovereignty aligns with the sovereign nation status that American Indian tribes and Alaska Native communities have with the United States. Furthermore, the worldviews that incorporate Indigenous communities' relational responsibilities to care for their food systems, according to their traditional practices and beliefs (Coté, 2016; Morrison, 2011), uniquely positions Indigenous peoples to lead food sovereignty initiatives. In this article, we explore what is currently known regarding food sovereignty and health. We then discuss opportunities to expand the evidence on Indigenous food sovereignty's relationships with (1) health and well being, (2) economics, (3) the natural environment, and (4) programming facilitators and barriers.

Food Systems, Food Sovereignty, and Health: Conference Shares Linkages to Support Indigenous Community Health.

The Center for Indigenous Innovation and Health Equity (CIIHE) at Oklahoma State University Center for Health Sciences (OSU-CHS) is a community-academic partnership with Indigenous peoples from Alaska, Hawai'i, and Oklahoma. The CIIHE supports communities to strengthen traditional food practices and food sovereignty and evaluate the impact of those efforts on health. In February 2022, the CIIHE sponsored and hosted a virtual conference to better understand how food sovereignty initiatives can improve health. More than 600 participants gathered to hear the latest research and practice in the areas of public health and agriculture, nutrition, community-based and Indigenous knowledge, and health economics. Community-led food sovereignty initiatives being implemented as part of the CIIHE were featured along with other Indigenous initiatives in urban, rural, and reservation communities. A survey was administered to conference participants to assess food sovereignty topics and priorities for future research. In this Practice Note, we describe innovative community-led initiatives presented as part of the conference and recommendations for action emerging from qualitative and quantitative data collected from conference participants.

Food Insecurity among American Indian and Alaska Native People: A Scoping Review to Inform Future Research and Policy Needs.

Food insecurity, defined as insufficient access to nutritious foods, is a social determinant of health that may underpin health disparities in the US. American Indian and Alaska Native (AI/AN) individuals experience many health inequities that may be related to food insecurity, but no systematic analyses of the existing evidence have been published. Thus, the objective of this scoping review was to assess the literature on food insecurity among AI/AN individuals and communities, with a focus on the prevalence of food insecurity and its relations to sociodemographic, nutrition, and health characteristics. Systematic search and data extraction processes were used. Searches were conducted on PubMed as well as peer-reviewed journal and government websites. Of 3174 identified references, 34 publications describing 30 studies with predominantly AI/AN sample populations were included in the final narrative synthesis. Twenty-two studies (73%) were cross-sectional and the remaining 8 (27%) described interventions. The weighted average prevalence of food insecurity across the studies was 45.7%, although estimates varied from 16% to 80%. Most studies used some version of the USDA Food Security Survey Modules, although evidence supporting its validity in AI/AN respondents is limited. Based on the review, recommendations for future research were derived, which include fundamental validity testing, better representation of AI/AN individuals in federal or local food security reports, and consideration of cultural contexts when selecting methodological approaches. Advances in AI/AN food insecurity research could yield tangible benefits to ongoing initiatives aimed at increasing access to traditional foods, improving food environments on reservations and homelands, and supporting food sovereignty.

Factors Associated with Matching into Surgical Specialties.

BACKGROUND: The United States medical education system has a vested interest in understanding medical student specialty choice. The purpose of this study is to identify the demographic, educational, lifestyle preference, and other factors associated with matching into surgical specialties. METHODS: An annual survey was given to students at the University of Iowa Carver College of Medicine from 2013-2019. 456 medical students were eligible to participate and 374 completed at least one survey. Surveys were distributed 5 times; M1, M2, M3, and M4 years and after the residency match process. Logistic regression was used to estimate the association between various factors and the likelihood of matching into a surgical specialty. RESULTS: Exposure to surgical fields, through a family member practicing surgery (aOR = 3.21), mentorship (aOR = 2.78), or research (aOR = 2.96) increase the likelihood of matching into a surgical specialty. Married students are less likely to pursue surgical specialties (aOR = 0.246). White students interested in surgery in their first two years of medical school were more likely (aOR = 6.472) to match into surgery than non-White students also interested in surgery (aOR = 0.155). CONCLUSIONS: Factors associated with an increased likelihood of matching into surgical specialties include having surgical mentors, performing surgical research, and having family members in surgical specialties. Of the students interested in surgery early in medical school, being of Caucasian ethnicity is associated with higher rates of matching into surgery. Students who are married without children are less likely to enter a surgical field.

Assessing factors for choosing a primary care specialty in medical students; A longitudinal study.

A shortage of primary care physicians exists in the US, and medical schools are investigating factors that influence specialty choice. To better understand the factors associated with medical students choosing primary care specialties, a longitudinal annual survey from 2013 to 2019 was administered to students at the University of Iowa Carver College of Medicine, starting pre-matriculation. A logistic regression model examined factors of interest. Matching into a primary care specialty (family medicine, internal medicine, pediatrics) for residency was the primary outcome. Our study compared factors students reported in annual surveys: demographics, mentorship, debt, and lifestyle. Factors significantly associated with primary care specialty included pre-medical and medical school research, a family member in primary care, student age and gender. 28% of men chose primary care, and 47% of women. Although there was no gender difference in rates of medical education debt (N = 286,χ2(1) = 0.28, p = 0.60), men were more likely to report being influenced by debt (N = 278, χ2(1) = 10.88, p = 0.001), and students who reported debt-influenced specialty choice were one-third as likely to enter primary care (N = 189, 95% CI [0.11-1.06], p = 0.06). For men, potential salary was negatively associated with entering primary care (p = 0.03). Women were more likely to have a mentor in primary care (N = 374, χ2(1) = 13.87, p < 0.001), but this was not associated with an increased likelihood of entering primary care for men or women. Having a family member who practices primary care was associated with a 2.87 times likelihood of entering primary care (N = 303, 95% CI [1.14-7.19], p = 0.03). The decision to enter primary care is influenced by many factors; a key gender differentiator is that men's specialty choice is more negatively influenced by financial concerns.

Testing the influence of testosterone administration on men's honesty in a large laboratory experiment.

The impact of testosterone on decision-making is a growing literature, with several reports of economically relevant outcomes. Similar to Wibral et al. (2012), we investigate the effects of exogenous testosterone administration on deception in a double-blind placebo controlled study. Participants (N = 242) were asked to roll a die in private and were paid according to their reported roll, which creates the opportunity to lie about the outcome to increase earnings. We find evidence for self-serving lying in both treatment and control groups and a statistically insignificant negative effect (d = -0.17, 95% CI[-0.42, 0.08]) indicating more honest behavior (i.e., lower reports) following testosterone administration. Although insignificant, the direction was the same as in the Wibral et al. study, and the meta-analytic effect of the two studies demonstrates lower reporting (i.e., more honesty) following testosterone (vs. placebo) administration, significant at the 0.05 level (d = -0.27, 95% CI[-0.49, -0.06]). We discuss how our results and methodology compare with Wibral et al. and identify potential causes for differences in findings. Finally, we consider several plausible connections between testosterone and lying that may be further investigated using alternative methodologies.
