OBJECTIVE:Whether and how dietary protein intake is linked to type 2 diabetes (T2D) remains unclear. The aim of this study was to investigate the associations of protein intake with development of T2D and the potential mediating roles of T2D biomarkers. RESEARCH DESIGN AND METHODS/METHODS:We included 108,681 postmenopausal women without T2D at baseline from the Women's Health Initiative (WHI) (primary cohort) and 34,616 adults without T2D from the U.K. Biobank (UKB) (replication cohort). Cox proportional hazard models were used for estimation of protein-T2D associations. Mediation analysis was performed to assess the mediating roles of biomarkers in case-control studies nested in the WHI. RESULTS:In the WHI, 15,842 incident T2D cases were identified during a median follow-up of 15.8 years. Intake of animal protein was associated with increased T2D risk (hazard ratio in comparing the highest to the lowest quintile = 1.31 [95% CI 1.24-1.37]) and plant protein with decreased risk (0.82 [0.78-0.86]). Intakes of red meat, processed meat, poultry, and eggs were associated with increased T2D risk and whole grains with decreased risk. Findings from the UKB were similar. These findings were materially attenuated after additional adjustment for BMI. Substituting 5% energy from plant protein for animal protein was associated with 21% decreased T2D risk (0.79 [0.74-0.84]), which was mediated by levels of hs-CRP, interleukin-6, leptin, and SHBG. CONCLUSIONS:Findings from these two large prospective cohorts support the notion that substituting plant protein for animal protein may decrease T2D risk mainly by reducing obesity-related inflammation.

Assessing Equitable Inclusion of Underrepresented Older Adults in Alzheimer's Disease, Related Cognitive Disorders, and Aging-Related Research: A Scoping Review

Godbole, Nisha; Kwon, Simona C; Beasley, Jeannette M; Roberts, Timothy; Kranick, Julie; Smilowitz, Jessica; Park, Agnes; Sherman, Scott E; Trinh-Shevrin, Chau; Chodosh, Joshua
BACKGROUND AND OBJECTIVES/OBJECTIVE:The rapidly aging and diversifying U.S. population is challenged by increases in prevalence of Alzheimer's disease (AD) and aging-related disorders. We conducted a scoping review to assess equitable inclusion of diverse older adult populations in aging research focused on National Institutes of Health (NIH)-sponsored research. RESEARCH DESIGN AND METHODS/METHODS:The scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-Scr) Protocol. The search was limited to NIH-funded studies focusing on aging, AD and Alzheimer's disease-related dementias (ADRD) and included adults aged 55+. The priority populations and health disparities put forth by the NIA Health Disparities Framework serve as a model for guiding inclusion criteria and for interpreting the representation of these underrepresented groups, including racial ethnic minorities, socioeconomically disadvantaged, rural populations, groups with disabilities, and LGBTQ communities. RESULTS:Our search identified 1,177 records, of which 436 articles were included in the analysis. Inclusion of individuals with ADRD and mild cognitive impairment, racial ethnic minorities, rural populations, socioeconomically disadvantaged, groups with disabilities, and LGBTQ communities were poorly specified in most studies. Studies used multiple recruitment methods, conducting studies in community settings (59%) and hospitals/clinics (38%) most frequently. Incentives, convenience factors, and sustained engagement via community-based and care partners were identified as key strategies for improved retention. DISCUSSION AND IMPLICATIONS/CONCLUSIONS:This scoping review identified gaps in existing literature and aims for future work, including stronger research focus on, better inclusion of, and improved data collection and reporting of older adults from underrepresented groups.

Diabetes and hypertension among South Asians in New York and Atlanta leveraging hospital electronic health records

Beasley, Jeannette M; Ho, Joyce C; Conderino, Sarah; Thorpe, Lorna E; Shah, Megha; Gujral, Unjali P; Zanowiak, Jennifer; Islam, Nadia
BACKGROUND:Diabetes and hypertension disparities are pronounced among South Asians. There is regional variation in the prevalence of diabetes and hypertension in the US, but it is unknown whether there is variation among South Asians living in the US. The objective of this study was to compare the burden of diabetes and hypertension between South Asian patients receiving care in the health systems of two US cities. METHODS:Cross-sectional analyses were performed using electronic health records (EHR) for 90,137 South Asians receiving care at New York University Langone in New York City (NYC) and 28,868 South Asians receiving care at Emory University (Atlanta). Diabetes was defined as having 2 + encounters with a diagnosis of diabetes, having a diabetes medication prescribed (excluding Acarbose/Metformin), or having 2 + abnormal A1C levels (≥ 6.5%) and 1 + encounter with a diagnosis of diabetes. Hypertension was defined as having 3 + BP readings of systolic BP ≥ 130 mmHg or diastolic BP ≥ 80 mmHg, 2 + encounters with a diagnosis of hypertension, or having an anti-hypertensive medication prescribed. RESULTS:Among South Asian patients at these two large, private health systems, age-adjusted diabetes burden was 10.7% in NYC compared to 6.7% in Atlanta. Age-adjusted hypertension burden was 20.9% in NYC compared to 24.7% in Atlanta. In Atlanta, 75.6% of those with diabetes had comorbid hypertension compared to 46.2% in NYC. CONCLUSIONS:These findings suggest differences by region and sex in diabetes and hypertension risk. Additionally, these results call for better characterization of race/ethnicity in EHRs to identify ethnic subgroup variation, as well as intervention studies to reduce lifestyle exposures that underlie the elevated risk for type 2 diabetes and hypertension development in South Asians.

Self-Rated Diet Quality and Cardiometabolic Health Among U.S. Adults, 2011-2018

Sullivan, Valerie K; Johnston, Emily A; Firestone, Melanie J; Yi, Stella S; Beasley, Jeannette M
INTRODUCTION:Self-rated health has been extensively studied, but the utility of a similarly structured question to rate diet quality is not well characterized. This study aims to assess the relative validity of self-rated diet quality, compared with that of a validated diet quality measure (Healthy Eating Index-2015) and to examine the associations with cardiometabolic risk factors. METHODS:Analyses were conducted in 2020-2021 using cross-sectional data from the National Health and Nutrition Examination Survey, 2011-2018. Nonpregnant adults who responded to the question: How healthy is your overall diet? and provided 2 dietary recalls were eligible (n=16,913). Associations between self-rated diet quality (modeled as a 5-point continuous variable, poor=1 to excellent=5) and Healthy Eating Index-2015 scores and cardiometabolic risk factors were assessed by linear regression, accounting for the complex survey design and adjusting for demographic and lifestyle characteristics. RESULTS:. CONCLUSIONS:Self-rated diet quality was associated with Healthy Eating Index-2015 scores and cardiometabolic disease risk factors. This single-item assessment may be useful in time-limited settings to quickly and easily identify patients in need of dietary counseling to improve cardiometabolic health.

Adaptation of a Dietary Screener for Asian Americans

Beasley, Jeannette M; Yi, Stella; Lee, Matthew; Park, Agnes; Thorpe, Lorna E; Kwon, Simona C; Rummo, Pasquale
No brief dietary screeners are available that capture dietary consumption patterns of Asian Americans. The purpose of this article is to describe the cultural adaptation of the validated Dietary Screener Questionnaire (DSQ) for use by clinicians, researchers, and community-based partners seeking to understand and intervene on dietary behaviors among English-speaking Asian Americans, for the six largest Asian subgroups (Chinese, Filipino, Asian Indian, Vietnamese, Korean, Japanese) in the United States. This was mainly accomplished by adding culturally specific examples of foods to the questionnaire items via searching online databases and soliciting input from members of our community partner network representing each of the six largest Asian subgroups. Over half of the 26 items on the DSQ were modified to include more culturally specific foods. Developing high-quality tools that reflect the diversity of the U.S. population are critical to implement nutrition interventions that do not inadvertently widen health disparities.

A Community Health Worker-Led Intervention to Improve Blood Pressure Control in an Immigrant Community With Comorbid Diabetes: Data From Two Randomized, Controlled Trials Conducted in 2011-2019

Beasley, Jeannette M; Shah, Megha; Wyatt, Laura C; Zanowiak, Jennifer; Trinh-Shevrin, Chau; Islam, Nadia S
Evidence-based strategies addressing comorbid hypertension and diabetes are needed among minority communities. We analyzed the outcome of blood pressure (BP) control using pooled data from two community health worker interventions in New York City conducted between 2011 and 2019, focusing on participants with comorbid hypertension and diabetes. The adjusted odds of controlled BP (< 140/90 mmHg) for the treatment group were significant compared with the control group (odds ratio = 1.4; 95% confidence interval = 1.1, 1.8). The interventions demonstrated clinically meaningful reductions in BP among participants with comorbid hypertension and diabetes.

Peer-Assisted Lifestyle (PAL) intervention: a protocol of a cluster-randomised controlled trial of a health-coaching intervention delivered by veteran peers to improve obesity treatment in primary care

Wittleder, Sandra; Smith, Shea; Wang, Binhuan; Beasley, Jeannette M; Orstad, Stephanie L; Sweat, Victoria; Squires, Allison; Wong, Laura; Fang, Yixin; Doebrich, Paula; Gutnick, Damara; Tenner, Craig; Sherman, Scott E; Jay, Melanie
INTRODUCTION/BACKGROUND:). Clinical guidelines recommend multicomponent lifestyle programmes to promote modest, clinically significant body mass (BM) loss. Primary care providers (PCPs) often lack time to counsel and refer patients to intensive programmes (≥6 sessions over 3 months). Using peer coaches to deliver obesity counselling in primary care may increase patient motivation, promote behavioural change and address the specific needs of veterans. We describe the rationale and design of a cluster-randomised controlled trial to test the efficacy of the Peer-Assisted Lifestyle (PAL) intervention compared with enhanced usual care (EUC) to improve BM loss, clinical and behavioural outcomes (aim 1); identify BM-loss predictors (aim 2); and increase PCP counselling (aim 3). METHODS AND ANALYSIS/UNASSIGNED:We are recruiting 461 veterans aged 18-69 years with obesity or overweight with an obesity-associated condition under the care of a PCP at the Brooklyn campus of the Veterans Affairs NY Harbor Healthcare System. To deliver counselling, PAL uses in-person and telephone-based peer support, a tablet-delivered goal-setting tool and PCP training. Patients in the EUC arm receive non-tailored healthy living handouts. In-person data collection occurs at baseline, month 6 and month 12 for patients in both arms. Repeated measures modelling based on mixed models will compare mean BM loss (primary outcome) between study arms. ETHICS AND DISSEMINATION/UNASSIGNED:The protocol has been approved by the Institutional Review Board and the Research and Development Committee at the VA NY Harbor Health Systems (#01607). We will disseminate the results via peer-reviewed publications, conference presentations and meetings with stakeholders. TRIAL REGISTRATION NUMBER/BACKGROUND:NCT03163264; Pre-results.

Training Medical Students in Diet Assessment and Brief Counseling

Johnston, Emily A; Beasley, Jeannette M; Jay, Melanie
Poor dietary choices are a leading cause of chronic disease, but nutrition is rarely discussed in clinical practice. Nutrition is taught in less than a third of medical schools and physicians in practice empirically report low levels of comfort and self-efficacy in discussing nutrition with patients. A two-part presentation was created and shared with second-year medical students at a college of medicine. Students were given pre-work that included a brief (15 minutes) pre-recorded presentation and an e-resource entitled "Practical Nutrition for the Primary Care Provider" and then engaged in a live virtual session with a brief lecture and question and answer period (45 minutes). A survey was administered following the live presentation to evaluate the extent to which the presentation met the stated objectives and could impact participants' future practice. One-hundred and six students participated in the live lecture. Eighty-eight students (83%) provided survey feedback. Over two-thirds of respondents indicated that the presentation completely met the objectives, 57% indicated that they would definitely talk to patients with chronic disease about nutrition, and 52% indicated they would incorporate diet assessment in visits with patients with chronic disease. Nutrition is integral to disease prevention and management. Many students provided comments on the importance of the topic and benefit of the information. Further research is necessary to determine the optimal time and place for nutrition education in medical training. This presentation and e-resource are evidence-based, brief, and provided tools for participants to access once in practice.

Relative validity and reliability of a diet risk score (DRS) for clinical practice

Johnston, Emily A; Petersen, Kristina S; Beasley, Jeannette M; Krussig, Tobias; Mitchell, Diane C; Van Horn, Linda V; Weiss, Rick; Kris-Etherton, Penny M
Introduction/UNASSIGNED:Adherence to cardioprotective dietary patterns can reduce risk for developing cardiometabolic disease. Rates of diet assessment and counselling by physicians are low. Use of a diet screener that rapidly identifies individuals at higher risk due to suboptimal dietary choices could increase diet assessment and brief counselling in clinical care. Methods/UNASSIGNED:We evaluated the relative validity and reliability of a 9-item diet risk score (DRS) based on the Healthy Eating Index (HEI)-2015, a comprehensive measure of diet quality calculated from a 160-item, validated food frequency questionnaire (FFQ). We hypothesised that DRS (0 (low risk) to 27 (high risk)) would inversely correlate with HEI-2015 score. Adults aged 35 to 75 years were recruited from a national research volunteer registry (ResearchMatch.org) and completed the DRS and FFQ in random order on one occasion. To measure reliability, participants repeated the DRS within 3 months. Results/UNASSIGNED:=0.36). The DRS ranked 37% (n=47) of subjects in the same quintile, 41% (n=52) within ±1 quintile of the HEI-2015 (weighted κ: 0.28). The DRS had high reliability (n=102, ICC: 0.83). DRS mean completion time was 2 min. Conclusions/UNASSIGNED:ClinicalTrials.gov (NCT03805373).
