Cultural Perceptions of Health in Asian Indian Adults.

OBJECTIVE: To gain an understanding of the cultural perceptions of health among Asian Indian adults in an urban setting. DESIGN: Qualitative semistructured interviews. SETTING: Midwest urban community PARTICIPANTS: Asian Indian adults (n = 20) aged ≥25 years, who self-identified as 100% Asian Indian descent. PHENOMENON OF INTEREST: Individual interviews were conducted by a trained interviewer to assess cultural perceptions of health. ANALYSIS: Transcript analysis was performed by 2 independent coders using verbatim transcripts. Content analysis was used to identify themes using a grounded theory approach. RESULTS: The salient themes that emerged were a cultural definition of health, acculturation, mental health, and health information. Participants believed good health was associated with the ability to perform daily activities, regular exercise, and eating well. There was a lack of awareness of Asian Indian-specific body mass index categories and that overweight and obesity were an important risk factor for chronic diseases. CONCLUSION AND IMPLICATIONS: These data provide a context for health promotion efforts and underscore a gap in awareness of risk factors risk for chronic diseases among the Asian Indian community. Culturally specific interventions targeted at the Asian Indian population, considering their worldview and perceptions of health, will help address this important public health concern.

Object Weight and Hand Dominance Impact Kinematics in a Functional Reach-to-Drink Task in School-Aged Children.

This study evaluates the effects of object weight and hand dominance on the end-point kinematics of the hand-to-mouth (withdrawal) movement in a functional reach-to-drink task for typically developing school-aged children. Using 3D motion capture, speed (average velocity and peak velocity), straightness (ratio), and smoothness (number of velocity peaks and log dimensionless jerk) of hand movements were calculated for the withdrawal motion with three different bottle weights (empty, half-filled, and full). Average velocity (550.4 ± 142.0 versus 512.1 ± 145.6 mm/s) and peak velocity (916.3 ± 234 versus 842.7 ± 198.4 mm/s) were significantly higher with the empty versus half-filled bottle and with the non-dominant (average: 543.5 ± 145.2 mm/s; peak: 896.5 ± 207 mm/s) versus dominant (average: 525.2 ± 40.7 mm/s; peak: 864.2 ± 209.2 mm/s) hand. There were no differences in straightness or smoothness. These findings indicate that increasing weight in reach-to-drink task puts greater constraints on the task. The slower movements with the dominant hand might denote better precision control than the non-dominant hand. The quantitative motion capture results show average values for the kinematic variables for a functional reach-to-drink task in a typically developing population of school-aged children with changing weights of the bottles that are relevant to a real-life scenario. These results could inform the design of individualized therapeutic interventions to improve functional upper-extremity use in children with neurodevelopmental motor disorders.

An Improved Assessment Method to Estimate (Poly)phenol Intake in Adults with Chronic Pancreatitis.

BACKGROUND: Insights into (poly)phenol exposure represent a modifiable factor that may modulate inflammation in chronic pancreatitis (CP), yet intake is poorly characterized and methods for assessment are underdeveloped. AIMS: The aims are to develop and test a method for estimating (poly)phenol intake from a 90-day food frequency questionnaire (FFQ) using the Phenol-Explorer database and determine associations with dietary patterns in CP patients versus controls via analysis of previously collected cross-sectional data. METHODS: Fifty-two CP patients and 48 controls were recruited from an ambulatory clinic at a large, academic institution. To assess the feasibility of the proposed methodology for estimating dietary (poly)phenol exposure, a retrospective analysis of FFQ data was completed. Mann-Whitney U tests were used to compare (poly)phenol intake by group; Spearman correlations and multivariable-adjusted log-linear associations were used to compare (poly)phenol intakes with dietary scores within the sample. RESULTS: Estimation of (poly)phenol intake from FFQs was feasible and produced estimates within a range of intake previously reported. Total (poly)phenol intake was significantly lower in CP vs controls (463 vs. 567mg/1000kcal; p = 0.041). In adjusted analyses, higher total (poly)phenol intake was associated with higher HEI-2015 (r = 0.34, p < 0.001), aMED (r = 0.22, p = 0.007), EDIH (r = 0.29, p < 0.001), and EDIP scores (r = 0.35, p < 0.001), representing higher overall diet quality and lower insulinemic and anti-inflammatory dietary potentials, respectively. CONCLUSIONS: Using enhanced methods to derive total (poly)phenol intake from an FFQ is feasible. Those with CP have lower total (poly)phenol intake and less favorable dietary pattern indices, thus supporting future tailored dietary intervention studies in this population.

A theoretical explanation for how a nutrition counseling and medically tailored meal delivery program benefitted participants living with lung cancer.

PURPOSE: The purpose of this study was to assess participants' perceptions and experiences while participating in a Food is Medicine medically tailored meal plus intensive nutrition counseling intervention to create a theoretical explanation about how the intervention worked. METHODS: This interpretive qualitative study included the use of semi-structured interviews with active participants in a randomized controlled trial aimed at understanding how a medically tailored meal plus nutrition counseling intervention worked for vulnerable individuals with lung cancer treated at four cancer centers across the USA. During the 8-month long study, participants in the intervention arm were asked to be interviewed, which were recorded, transcribed verbatim, and analyzed using conventional content analysis with principles of grounded theory. RESULTS: Twenty individuals participated. Data analysis resulted in a theoretical explanation of the intervention's mechanism of action. The explanatory process includes three linked and propositional categories leading to patient resilience: engaging in treatment, adjusting to diagnosis, and active coping. The medically tailored meals plus nutrition counseling engaged participants throughout treatment, which helped participants adjust to their diagnosis, leading to active coping through intentional self-care, behavior change, and improved quality of life. CONCLUSIONS: These findings provide evidence that a Food is Medicine intervention may buffer some of the adversity related to the diagnosis of lung cancer and create a pathway for participants to experience post-traumatic growth, develop resilience, and change behaviors to actively cope with lung cancer. Medically tailored meals plus intensive nutrition counseling informed by motivational interviewing supported individuals' adjustment to their diagnosis and resulted in perceived positive behavior change.

E-PROOF: E-intervention for protein intake and resistance training to optimize function: A study protocol.

BACKGROUND: Accounting for more than 60% of cancer survivors, older (≥65 years) cancer survivors have a 2- to 5-fold risk of physical function impairment, compared to cancer-free peers. One strategy to improve physical function is dietary and resistance training interventions, which improve muscle strength and mass by stimulating muscle protein synthesis. The E-PROOF (E-intervention for Protein Intake and Resistance Training to Optimize Function) study will examine the feasibility, acceptability, and preliminary efficacy of a 12-week randomized controlled trial of an online, tailored nutritional and resistance training education and counseling intervention to improve physical function and associated health outcomes (muscle strength, health-related quality of life (HRQoL), self-efficacy, and weight management). METHODS: In this study, 70 older cancer survivors will be randomized to one of two groups: experimental (receiving remote behavioral counseling and evidence-based education and resources), and control (general survivorship education). We will examine the intervention effects on physical function, muscle strength, HRQoL, self-efficacy, weight, and waist circumference during a 12-week period between the experimental and control groups. Three months following the end of the intervention, we will conduct a follow-up assessment to measure physical function, muscle strength, and HRQoL. SIGNIFICANCE AND IMPACT: This study is the first synchronous, online protein-focused diet and resistance training intervention among older cancer survivors. This novel study advances science by promoting independent health behaviors among older cancer survivors to improve health outcomes, and provide foundational knowledge to further address this growing problem on a wider scale through online platforms.

How a Medically Tailored Meal Intervention with Intensive Nutrition Counseling Created Active Coping with Behavior Change for Vulnerable Patients with Lung Cancer.

Purpose: The purpose of this study was to assess participants' perceptions and experiences while participating in a Food is Medicine medically tailored meal plus nutrition counseling intervention to create a theoretical explanation about how the intervention worked. Methods: This interpretive qualitative study included the use of semi-structured interviews with active intervention participants. Purposeful sampling included vulnerable (uninsured, rural zip code residency, racial/ethnic minority, 65 years old, and/or low-income) individuals with lung cancer treated at four cancer centers across the United States. Interviews were recorded, transcribed verbatim, and analyzed using conventional content analysis with principles of grounded theory. Results: Twenty individuals participated. Data analysis resulted in a theoretical explanation of the intervention's mechanism of action. The explanatory process includes 3 linked and propositional categories leading to patient resilience: engaging in treatment, adjusting to diagnosis, and active coping. The medically tailored meals plus intensive nutrition counseling engaged participants throughout treatment, which helped participants adjust to their diagnosis, leading to active coping through intentional self-care, behavior change, and improved quality of life. Conclusions: These findings provide evidence that a food is medicine intervention may buffer some of the adversity related to the diagnosis of lung cancer and create a pathway for participants to experience post-traumatic growth, develop resilience, and change behaviors to actively cope with lung cancer. Medically tailored meals plus intensive nutrition counseling informed by motivational interviewing supported individuals' adjustment to their diagnosis and resulted in perceived positive behavior change.

Optimizing clinical nutrition research: the role of adaptive and pragmatic trials.

Evidence-based nutritional recommendations address the health impact of suboptimal nutritional status. Efficacy randomized controlled trials (RCTs) have traditionally been the preferred method for determining the effects of nutritional interventions on health outcomes. Nevertheless, obtaining a holistic understanding of intervention efficacy and effectiveness in real-world settings is stymied by inherent constraints of efficacy RCTs. These limitations are further compounded by the complexity of nutritional interventions and the intricacies of the clinical context. Herein, we explore the advantages and limitations of alternative study designs (e.g., adaptive and pragmatic trials), which can be incorporated into RCTs to optimize the efficacy or effectiveness of interventions in clinical nutrition research. Efficacy RCTs often lack external validity due to their fixed design and restrictive eligibility criteria, leading to efficacy-effectiveness and evidence-practice gaps. Adaptive trials improve the evaluation of nutritional intervention efficacy through planned study modifications, such as recalculating sample sizes or discontinuing a study arm. Pragmatic trials are embedded within clinical practice or conducted in settings that resemble standard of care, enabling a more comprehensive assessment of intervention effectiveness. Pragmatic trials often rely on patient-oriented primary outcomes, acquire outcome data from electronic health records, and employ broader eligibility criteria. Consequently, adaptive and pragmatic trials facilitate the prompt implementation of evidence-based nutritional recommendations into clinical practice. Recognizing the limitations of efficacy RCTs and the potential advantages of alternative trial designs is essential for bridging efficacy-effectiveness and evidence-practice gaps. Ultimately, this awareness will lead to a greater number of patients benefiting from evidence-based nutritional recommendations.

Association between glycemic control and group B streptococcus colonization among pregnant individuals with pregestational diabetes.

PROBLEM: Pregestational diabetes increases the risk of group B streptococcus (GBS) colonization in pregnancy. Whether glycemic control is associated with differences in this risk is unknown. We examined the association between glycemic control and GBS colonization among pregnant individuals with pregestational diabetes. METHOD OF STUDY: A retrospective cohort of pregnant individuals with pregestational diabetes at a tertiary care center. The exposure was glycemic control, measured as hemoglobin A1c (A1c) at >20 weeks and assessed categorically at thresholds of <6.5% and <6.0%, and secondarily, as a continuous percentage. The outcome was maternal GBS colonization. Multivariable logistic regression was used and adjusted for age, parity, race, and ethnicity as a social determinant, body mass index, type of diabetes, and gestational age at A1c assessment. RESULTS: Among 305 individuals (33% Type 1, 67% type 2), 45.0% (n = 140) were colonized with GBS. Individuals with an A1c < 6.5% were half as likely to be colonized with GBS compared with those with a A1c ≥ 6.5% (38.8% vs. 53.9%; adjusted odds ratio, AOR: 0.55; 95% CI: 0.33-0.91). Results were unchanged at an A1c threshold of <6.0% (35.7% vs. 48.5%; AOR: 0.60; 95% CI: 0.36-0.98). Individuals with a higher A1c as a continuous measure (%) were more likely to be colonized (AOR: 1.57 per 1%; 95% CI: 1.25-1.97). CONCLUSIONS: Pregnant individuals with pregestational diabetes with worse glycemic control were at an increased risk of GBS colonization. Further study is needed to understand if improved glycemic control leads to lower risk of GBS colonization.

Task-Related Differences in End-Point Kinematics in School-Age Children with Typical Development.

Understanding whether and how children with typical development adapt their reaches for different functional tasks could inform a more targeted design of rehabilitation interventions to improve upper extremity function in children with motor disabilities. This prospective study compares timing and coordination of a reach-to-drink, reach-to-eat, and a bilateral reaching task in typically developing school-aged children. Average speed, straightness, and smoothness of hand movements were measured in a convenience sample of 71 children, mean age 8.77 ± 0.48 years. Linear mixed models for repeated measures compared the variables by task, phases of the reach, task x phase interactions, and dominant versus non-dominant hands. There were significant main effects for task and phase, significant task x phase interactions (p < 0.05), and a significant difference between the dominant and non-dominant hand for straightness. Hand movements were fastest and smoothest for the reach-to-eat task, and least straight for the bilateral reaching task. Hand movements were also straighter in the object transport phases than the prehension and withdrawal phases. These results indicate that children with typical development change their timing and coordination of reach based on the task they are performing. These results can inform the design of rehabilitation interventions targeting arm and hand function.

Rationale and design of the linking education, produce provision, and community referrals to improve diabetes care (LINK) study.

BACKGROUND: Individuals with type 2 diabetes (T2D) experiencing food insecurity may have other non-medical, health-related social needs (e.g., transportation, housing instability) that decrease their ability to attain T2D control and impact other health outcomes. METHODS: A pragmatic randomized controlled trial (pRCT) to test the effect of produce provision, diabetes and culinary skills training and education, and social needs screening, navigation, and resolution, on hemoglobin A1c (A1c) levels in individuals with T2D (A1c ≥7.5%) experiencing food insecurity; a cost-effectiveness evaluation of the interventions that comprise the pRCT; and a process evaluation to understand the contextual factors that impact the uptake, effectiveness, and sustainability of the interventions. SETTING: Ambulatory care clinics (e.g., family medicine, general internal medicine, endocrinology) affiliated with an academic medical center in an urban environment in the Midwest. DESIGN: 2 × 2 factorial design. INTERVENTIONS: Cooking Matters for Diabetes is a 6-week diabetes and culinary education intervention. The Health Impact Ohio Central Ohio Pathways Hub intervention is a community health worker model designed to evaluate and address participants' social needs. All participants will receive referral to the Mid-Ohio Farmacy to provide weekly access to fresh produce. OUTCOMES: Primary outcome of the pRCT is change in A1c at 3 months; secondary outcomes include A1c at 6 months, and diabetes self-efficacy, food insecurity, and diet quality at 3 and 6 months. DISCUSSION: Food insecurity, unmet social needs, diabetes education and self-efficacy are critical issues that must be addressed to improve T2D treatment, care, and health equity.

Differences in Adherence to American Heart Association's Life's Essential 8, Diet Quality, and Weight Loss Strategies Between Those With and Without Recent Clinically Significant Weight Loss in a Nationally Representative Sample of US Adults.

Background The American Heart Association defines ideal cardiovascular health based on 8 risk factors (Life's Essential 8 [LE8]); a high LE8 score (range 0-100) reflects greater adherence to their recommendations. Weight status influences cardiovascular health, yet individuals may use detrimental diet and weight loss strategies to improve weight status. We assessed differences in LE8 adherence, diet quality, and weight loss strategies between those with and without a recent history of clinically significant weight loss (CSWL). Methods and Results Data from 2007 to 2016 National Health and Nutrition Examination Survey questionnaires, clinical measures, and 24-hour dietary recalls were assessed to determine LE8 adherence, diet quality (Healthy Eating Index), and weight loss strategies between adults with: (1) intentional CSWL ≥5%; and (2) non-CSWL <5%, weight maintenance, or weight gain over the past 12 months using ANCOVA and chi-square tests. Those with CSWL demonstrated higher scores for diet quality (P=0.014), physical activity (P<0.001), and blood lipids (P<0.001). Those without CSWL reported lower BMI (P<0.001). There were no differences in total LE8 cardiovascular health scores between those with and without CSWL. More individuals with CSWL reported weight loss strategies of exercising (P=0.016); those without CSWL reported skipping meals (P=0.002) and using prescription diet pills (P<0.001). Conclusions Greater adherence to the LE8 recommendations was observed among individuals with CSWL, although overall LE8 scores were low. Future research should address the implementation of evidence-based strategies that improve diet quality while promoting optimal cardiovascular health among those with intent to lose weight.

Preliminary Support for the Use of Motivational Interviewing to Improve Parent/Adult Caregiver Behavior for Obesity and Cancer Prevention.

Motivational interviewing (MI) is a promising behavioral intervention for improving parent and adult caregiver (PAC) health behavior for obesity and cancer prevention. This study explored the preliminary effects of MI from a registered dietitian (RDMI) within an obesity prevention intervention to promote PAC behavior change and positive proxy effects on children and the home environment. N = 36 PAC/child dyads from low-resource communities were enrolled in a randomized trial testing a 10-week obesity prevention intervention. Intervention dyads were offered RDMI sessions. Data were collected at baseline and post-intervention (PAC diet quality (Healthy Eating Index (HEI)), child skin carotenoids, home environment, and PAC ambivalence regarding improving diet). Results show that for every RDMI dose, PAC HEI scores increased (0.571 points, p = 0.530), child skin carotenoid scores improved (1.315%, p = 0.592), and the home food environment improved (3.559%, p = 0.026). There was a significant positive relationship between RDMI dose and change in ambivalence (ρ = 0.533, p = 0.007). Higher baseline ambivalence was associated with greater dose (ρ = -0.287, p = 0.173). Thus, RDMI for PACs may improve diets among PACs who are otherwise ambivalent, with potential effects on the diets of their children and the home food environment. Such intervention strategies have the potential for greater effect, strengthening behavioral interventions targeting obesity and cancer.

Changes in Child Weight, Behaviors, and Family Dynamics during Parental Participation in a Medical Weight Management Program: A Longitudinal Uncontrolled Pilot Study.

Background: There is limited evidence of the effects of parental participation in outpatient medical weight management (MWM) programs on children. The aims of the project were to (1) identify time effects from parental participation in the MWM program on changes in child weight trajectories, healthy and unhealthy weight control practices, physical and sedentary activity, parental restrictive feeding and pressure to eat, and family functioning and communication and (2) determine differences based on child factors. Methods: A longitudinal uncontrolled pilot study was conducted, in which parent-child (ages 7-19) dyads completed assessments at parents' MWM program initiation, 3 months (mid-program), 6 months (end of program), and 12 months to determine sustained effects. Repeated measures analysis of variance (ANOVA) was completed using a mixed multilevel modeling approach using Restricted Maximum Likelihood estimation method; each outcome was additionally analyzed with child baseline weight status, age group, and sex as between-subjects factors. Results: Fifty three dyads met inclusion criteria, 23 completed the initial assessment (enrollment: 43.3%), and 13 completed the 12-month assessment (retention: 56.5%). Significant effects over time were observed for decreased parental restrictive feeding (p < 0.038) over 12 months, and group by time effects were observed for increased restrictive feeding for female compared to male children (p = 0.025) over 12 months. Marginally significant group by time effects were found for increased impaired family functioning (p = 0.054) and communication (p = 0.054) for children with overweight/obesity compared to healthy weight children over 12 months. Conclusions: Female children and children with overweight/obesity may experience increased negative family dynamics (restriction of food, family functioning, and communication) through parental MWM programs.

Feasibility of Cooking Matters for Diabetes: A 6-week Randomized, Controlled Cooking and Diabetes Self-Management Education Intervention.

BACKGROUND: Diabetes self-management education and support is the cornerstone of diabetes care, yet <10% of adults with diabetes manage their condition successfully. Feasible interventions are needed urgently. OBJECTIVE: Our aim was to assess the feasibility of a cooking intervention with food provision and diabetes self-management education and support. DESIGN: This was a waitlist-controlled, randomized trial. PARTICIPANTS/SETTING: Thirteen adults with type 1 or type 2 diabetes who participated in Cooking Matters for Diabetes (CMFD) participated in 2 focus groups. INTERVENTION: CMFD was adapted from Cooking Matters and the American Diabetes Association's diabetes self-management education and support intervention into a 6-week program with weekly lesson-aligned food provisions. MAIN OUTCOME MEASURES: Feasibility was evaluated quantitatively and qualitatively along the following 5 dimensions: demand, acceptability, implementation, practicality, and limited efficacy. STATISTICAL ANALYSIS: Two coders extracted focus group themes with 100% agreement after iterative analysis, resulting in consensus. Administrative data were analyzed via descriptive statistics. RESULTS: Mean (SD) age of focus group participants was 57 (14) years; 85% identified as female; 39% identified as White; 46% identified as Black; and income ranged from <$5,000 per year (15%) to $100,000 or more per year (15%). Mean (SD) baseline hemoglobin A1c was 8.6% (1.2%). Mean attendance in CMFD was 5 of 6 classes (83%) among all participants. Demand was high based on attendance and reported intervention utilization and was highest among food insecure participants, who were more likely to report using the food provisions and recipes. Acceptability was also high; focus groups revealed the quality of instructors and interaction with peers as key intervention strengths. Participant ideas for implementation refinement included simplifying recipes, lengthening class sessions, and offering more food provision choices. Perceived effects of the intervention included lower hemoglobin A1c and body weight and improvements to health-related quality of life. CONCLUSIONS: The CMFD intervention was feasible according to the measured principles of demand, acceptability, implementation, practicality, and limited efficacy.

Outcomes of Cooking Matters for Diabetes: A 6-week Randomized, Controlled Cooking and Diabetes Self-Management Education Intervention.

BACKGROUND: Diabetes self-management education and support is the cornerstone of diabetes care, yet only 1 in 2 adults with diabetes attain hemoglobin A1c (HbA1c) targets. Food insecurity makes diabetes management and HbA1c control more difficult. OBJECTIVE: Our aim was to test whether a cooking intervention with food provision and diabetes self-management education and support improves HbA1c and diabetes management. DESIGN: This was a waitlist-controlled, randomized trial. PARTICIPANTS/SETTING: Participants were 48 adults with type 1 or type 2 diabetes. INTERVENTION: Cooking Matters for Diabetes was adapted from Cooking Matters and the American Diabetes Association diabetes self-management education and support intervention into a 6-week program with weekly food provision (4 servings). MAIN OUTCOME MEASURES: Surveys (ie, Summary of Diabetes Self-Care Activities; Medical Outcomes Study Short Form Health Survey, version 1; Diet History Questionnaire III; 10-item US Adult Food Security Survey Module; and Stanford Diabetes Self-Efficacy Scale) were administered and HbA1c was measured at baseline, post intervention, and 3-month follow-up. STATISTICAL ANALYSIS: Mixed-effects linear regression models controlling for sex and study wave were used. RESULTS: Mean (SD) age of participants was 57 (12) years; 65% identified as female, 52% identified as White, 40% identified as Black, and 19 (40%) were food insecure at baseline. Intervention participants improved Summary of Diabetes Self-Care Activities general diet score (0 to 7 scale) immediately post intervention (+1.51; P = .015) and 3 months post intervention (+1.23; P = .05), and improved Medical Outcomes Study Short Form Health Survey, version 1, mental component score (+6.7 points; P = .025) compared with controls. Healthy Eating Index 2015 total vegetable component score improved at 3 months (+0.917; P = .023) compared with controls. At baseline, food insecure participants had lower self-efficacy (5.6 vs 6.9 Stanford Diabetes Self-Efficacy Scale; P = .002) and higher HbA1c (+0.77; P = .025), and demonstrated greater improvements in both post intervention (+1.2 vs +0.4 Stanford Diabetes Self-Efficacy Scale score; P = .002, and -0.12 vs +0.39 HbA1c; P = .25) compared with food secure participants. CONCLUSIONS: Cooking Matters for Diabetes may be an effective method of improving diet-related self-care and health-related quality of life, especially among food insecure patients, and should be tested in larger randomized controlled trials.

Facilitating a high-quality dietary pattern induces shared microbial responses linking diet quality, blood pressure, and microbial sterol metabolism in caregiver-child dyads.

Low-resource individuals are at increased risk of obesity and cardiovascular disease (CVD), partially attributable to poor dietary patterns and dysfunctional microbiota. Dietary patterns in childhood play critical roles in physiological development and are shaped by caregivers, making caregiver-child dyads attractive targets for dietary interventions to reduce metabolic disease risk. Herein, we targeted low-resource caregiver-child dyads for a 10-week, randomized, controlled, multifaceted lifestyle intervention including: nutrition and physical activity education, produce harvesting, cooking demonstrations, nutrition counseling, and kinetic activites; to evaluate its effects on dietary patterns, CVD risk factors, and microbiome composition. Subjects in the lifestyle intervention group improved total diet quality, increased whole grain intake, decreased energy intake, and enhanced fecal elimination of the microbe-derived metabolite lithocholic acid (LCA) in contrast to control subjects. Microbiomes were highly personalized, similar within dyads, and altered by lifestyle intervention. Differential modeling of microbiome composition identified taxa associated with total diet quality, whole grain intake, and LCA elimination including recognized fiber-degrading bacteria such as Subdoligranulum, and bile acid metabolizing organisms like Bifidobacterium. Inclusion of taxa identified in diet and metabolite modeling within blood pressure models improved prediction accuracy of microbiome-blood pressure associations. Importantly, microbiota-blood pressure relationships were shared between dyads, implying shared host-microbiota responses to lifestyle intervention. Overall, these outcomes provide insight into mechanisms by which dietary interventions impact the gut-cardiovascular axis to reduce future CVD risk. Registered at clinicaltrials.gov: NCT05367674.

Collection of biospecimens from parent-child dyads in a community garden-based nutrition intervention: protocol and feasibility.

BACKGROUND: Non-invasive human biospecimens, including stool, urine, and hair, are important in understanding the relationship between diet and changes in human physiologic processes that affect chronic disease outcomes. However, biospecimen collection can be difficult when collecting samples for research studies that occur away from a centralized location. We describe the protocol and feasibility in collecting stool, urine, and hair biospecimens from parents and their children at a remote location as a part of a summer community garden-based intervention. METHODS: Stool, urine, and hair were collected as a part of the Summer Harvest Adventure (SHA) study, a randomized controlled, community garden-based intervention targeting children (ages 8-11 years) and their parents from low-resource neighborhoods. Biospecimens were collected from willing children and/or their parent/adult caregivers at baseline and post-intervention for evaluation of microbiome, metabolomics, and hair analyses among both intervention and control groups at a location distant from the academic laboratories conducting the analysis. The protocol used to assemble, deliver, collect, and process biospecimens are presented along with the frequencies with which specimens were successfully obtained. RESULTS: One hundred forty six participants (73 parent-child dyads) were part of the larger SHA study and thus eligible to provide a biospecimen. A total of 126 participants, 115 participants, and 127 participants consented to provide their hair, stool and urine samples, respectively. Of the participants that consented to provide a sample, 44 children (69.8%) and 38 parents (60.3%) provided at least one hair sample, 27 children (48.2%) and 37 parents (62.7%) provided at least one stool sample, and 36 children (57.1%) and 42 parents (65.6%) provided at least one urine sample. Sample collection at the offsite location, transport, and handling at the academic center were successful and all biospecimens were deemed adequate for analyses. DNA and metabolomics yield on a subset of stool samples obtained provided excellent results in terms of an abundance of species and metabolities, as would be predicted. Urine and hair analyses are underway. CONCLUSION: Our work is one of the first to describe the feasibility of collecting human biospecimens, specifically stool, urine, and hair, from both parents and their children from low-resourced neighborhoods in a non-traditional garden research setting. Future work will report findings related to mechanisms between diet, microbiome, metabolites, and clinical outcomes.

Application of the Updated WCRF/AICR Cancer Prevention Score as an Outcome for Cancer Survivors Participating in a Tailored and Intensive Dietary and Physical Activity Intervention.

The World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) has defined evidence-based guidelines for cancer prevention. These recommendations have been operationalized into a quantitative index for individual assessment. Survivors of cancer are increasingly desiring guidance for diet and lifestyle, and in the absence of research in survivors, are often instructed to follow cancer prevention and public health guidelines. In this study, we examine the utility of the quantitative updated WCRF/AICR scoring criteria to assess change among cancer survivors with overweight/obesity (OW/OB) following an intensive behavioral intervention. We applied the WCRF/AICR scoring criteria (range 0−7) to examine changes over the duration of the study by paired t-tests. Two cancer survivor cohorts with OW/OB (n = 91) completed a six-month phase II clinical trial designed to improve dietary and physical activity patterns. At enrollment and post-intervention, participants completed assessments including anthropometrics, food frequency questionnaires, and objective evaluation of physical activity. Participants improved adherence to all scored recommendations, with a significant increase in mean score from enrollment (3.22 ± 1.06) to post-intervention (4.28 ± 1.04) (p < 0.001). Mean BMI and waist circumference improved (both p < 0.001). The greatest improvements were noted for fruit and non-starchy vegetable intakes (+39%, p < 0.001); the greatest decreases were observed for processed meat consumption (−70%, p < 0.001). The updated WCRF/AICR Score can be applied to cancer survivor intervention studies and provides a tool to compare trials in regard to the baseline status of populations enrolled and the success of the intervention. Future interventions incorporating standardized assessments will help guide effective strategies to improve the health and quality of life for cancer survivors.

American Cancer Society nutrition and physical activity guideline for cancer survivors.

The overall 5-year relative survival rate for all cancers combined is now 68%, and there are over 16.9 million survivors in the United States. Evidence from laboratory and observational studies suggests that factors such as diet, physical activity, and obesity may affect risk for recurrence and overall survival after a cancer diagnosis. The purpose of this American Cancer Society guideline is to provide evidence-based, cancer-specific recommendations for anthropometric parameters, physical activity, diet, and alcohol intake for reducing recurrence and cancer-specific and overall mortality. The audiences for this guideline are health care providers caring for cancer survivors as well as cancer survivors and their families. The guideline is intended to serve as a resource for informing American Cancer Society programs, health policy, and the media. Sources of evidence that form the basis of this guideline are systematic literature reviews, meta-analyses, pooled analyses of cohort studies, and large randomized clinical trials published since 2012. Recommendations for nutrition and physical activity during cancer treatment, informed by current practice, large cancer care organizations, and reviews of other expert bodies, are also presented. To provide additional context for the guidelines, the authors also include information on the relationship between health-related behaviors and comorbidities, long-term sequelae and patient-reported outcomes, and health disparities, with attention to enabling survivors' ability to adhere to recommendations. Approaches to meet survivors' needs are addressed as well as clinical care coordination and resources for nutrition and physical activity counseling after a cancer diagnosis.

The Associations between Dietary Supplement Use, Diet Quality, and Health-Related Quality of Life among Older Female Cancer Survivors.

Evidence-based guidelines for cancer survivorship do not recommend dietary supplementation, yet older cancer survivors report high prevalence of dietary supplement use, specifically multivitamin (MVM), calcium, and vitamin D. Female cancer survivors (≥65 years) who were ≤5 years post-cancer diagnosis completed questionnaires assessing health-related quality of life (HRQoL), diet quality, and supplement intake. Intakes of MVM, calcium, and vitamin D supplementation were 61.4%, 76.9%, and 35.3%, respectively. Women who used MVM supplements had significantly higher dietary quality mean scores for total vegetables (4.5 ± 0.9 to 4.1 ± 1.1), greens and beans (4.1 ± 1.3 to 3.6 ± 1.6), whole fruit (4.7 ± 0.8 to 4.3 ± 1.3), and whole grains (2.9 ± 1.8 to 2.3 ± 1.6) than those who did not use these supplements. After controlling for demographic and clinical variables, the odds of MVM use was 1.07 times greater among those women who had higher total HEI scores. Participants with lower HRQoL were 4% more likely to take an MVM. Understanding the prevalence of supplementation, associations with diet quality, and perceived benefits of supplementation may help healthcare providers in educating survivors and promoting adherence to the evidence-based guidelines.
