Abstract Background Parents are increasingly pursuing weight loss in medical weight management programs, yet little is known about the presenting behaviors and practices of children who have parents initiating these programs. Objective To describe congruence in weight control practices, sedentary and screen time behaviors, and family functioning and communication between parents initiating a medical weight management program and their children (ages 7–18). Methods Twenty‐three dyads were enrolled and had measured height/weight and research packets completed including perceived weight status, weight control practices, sedentary and screen‐time behaviors, and family functioning and communication. Paired t‐tests and intraclass correlations assessed congruence; independent t‐tests determined differences based on child demographics (age, sex, and weight status). Results Parents underestimated children's use of weight control practices compared to child reports. Children with overweight, males, and older in age had increased weight control practices and sedentary and screen‐time behaviors. Children who perceived themselves to have overweight reported more impaired family communication than children perceived to be a healthy weight. Conclusions This study highlights the discrepancy between dyads' reports of children's behaviors, and identifies that specific child populations with overweight, older in age, and males are at‐risk of experiencing less healthy behaviors and impaired family communication. Future research should monitor changes over time in parental weight management programs to determine effects based on parental weight loss.

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., (© 2024.

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., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Krok-Schoen et al.

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., Competing Interests: Financial interests: The authors have no relevant financial or non-financial interests to disclose.

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.

One area within geriatric oncology that is understudied and undertreated is the dietary quality of older cancer survivors. Most older adults with cancer experience nutritional deficits due to their age and cancer treatment. Research has shown the impact of competing comorbidities, polypharmacy, and decline in functional and cognitive status on older adults' nutritional needs. This study sought to examine the diet quality of older female cancer survivors, and its association with inflammatory markers and physical functioning. Participants completed surveys online, by mail, or phone. Additional participant information was obtained through medical records. Descriptive statistics, Pearson's correlations, forward linear regressions were used to analyze these data. Older female cancer survivors (≥65) that had completed their initial cancer treatment in the past 5 years were recruited through cancer clinic visits and medical records. The study was conducted from November 2018 through January 2020. Self-reported physical functioning (RAND-36), diet quality (DHQ-II, HEI-2015), and BMI were obtained from surveys. Participant diagnosis, comorbidities, and inflammatory marker (c-reactive protein (CRP)) were obtained through electronic medical records; albumin was collected as a marker correlated with inflammation. The average age of participants ( n  = 171) was 73.6 ± 8.4 years. Mean physical functioning score was 60 ± 24 out of 100. Mean total HEI scores were 66.39 + 10.0 out of 100. Positive correlations were observed between total HEI scores and physical functioning, self-rated health, albumin, education, and income. Negative correlations were observed between physical functioning and BMI, self-rated health, albumin, and age. Regressions indicated that individuals who had higher HEI scores were more likely to report higher physical functioning ( β  = 0.38, P  < 0.001). Identifying dietary quality and markers to overall assess inflammation is pertinent to improve the long-term health of cancer survivors. The strong correlations between physical function, HEI, and albumin demonstrates the relationship albumin has with inflammation and its subtle impact it can have on older cancer survivors. Along with CRP, serum albumin should be interpreted in the context of the patient's overall health. Future larger cohort studies of older cancer survivors with longitudinal measurements are warranted.

Objective: We aimed to investigate the associations between diet quality, general health, and comorbidities among older female cancer survivors. Methods: Participants ( n = 171) completed one-time surveys to assess health-related quality of life (RAND-36), diet quality (Healthy Eating Index (HEI-2015)), and number of comorbidities. Additional demographic and clinical variables were collected. Descriptive statistics, analysis of covariance, correlations, and linear regressions were utilized. Results: A positive correlation was found between HEI-2015 and general health subscale scores (r = .26, p = .002). A negative correlation was found between the number of comorbidities and general health (r = -.21, p = .02). Being white (β = -.24, p = .02) and having fewer comorbidities (β = -.22, p = .04) were significantly associated with higher general health. Being unmarried (β = .24, p = .02) and having higher education (β = .32, p = .002) were significantly associated with higher HEI-2015 scores. Discussion: Healthcare providers should seek guidance from registered dietitian nutritionists for nutritional education to promote optimal nutritional status, thus contributing to improved general health among this growing population.

(1) The objective was to determine changes in parent-child (ages 7-18) dyad skin carotenoids spanning parental participation in a medical weight management program (WMP), and associations with parent BMI, child BMIz, fruit/vegetable intake, and family meals and patterns. (2) The study design was a longitudinal dyadic observational study with assessment at WMP initiation, mid-point (3-months), and conclusion (6-months). Twenty-three dyads initiated the study, 16 provided assessments at 3 months, and 11 at program conclusion. Associations between parent and child carotenoids (dependent variables) and parent BMI, child BMIz, increases in fruit/vegetable intake, and family meals and patterns were analyzed using Pearson's correlations and independent samples t-tests. Repeated measures ANOVA assessed changes in weight status and carotenoids. (3) Parents experienced significant declines in BMI and skin carotenoid levels over 6 months. Parent and child carotenoids were correlated at each assessment. At initiation, parent BMI and carotenoids were inversely correlated, child carotenoids were associated with increased family meals, and never consuming an evening fast food or restaurant meal were associated with increased parent and child carotenoids. (4) Results demonstrate skin carotenoids are strongly correlated within dyads and may be associated with lower parental BMI and positive family meal practices.

Short chain fatty acids (SCFAs), generated from microbial fermentation of dietary fibers, can regulate weight, appetite and energy homeostasis. Therefore, measuring SCFAs in fecal samples is important to understand the relationship between dietary patterns, gut microbial metabolism, and their impact on host metabolism homeostasis. However, due to the chemical complexity of fecal samples and the volatility of these SCFAs, the quantitative measurements of SCFAs remain challenging. In this study, we developed an absolute quantitation method for accurate and reliable analysis of SCFAs using an UPLC-Q Exactive HRMS system. Nine C2-C6 SCFAs were first derivatized and then separated on a reversed-phase CSH C18 column, and quantitated by UPLC-HRMS with targeted-selected ion monitoring (t-SIM) mode. Our calibration plots showed high linearity (R 2 >0.99) with high quantitation accuracy (from 91.24%-118.42%); additional analyses showed excellent precisions ranging from 1.12 % to 6.13 %, and accurate recoveries between 92.38 % and 109.65 % with relative standard deviations of 0.31 %-6.44 %. Meanwhile, the short-term stability, freeze and thaw stability, and 168 h storage stability were tested and reported from 85.07%-106.44% with RSDs 0.44%-20.00%, 98.99%-128.84% with RSDs 0.77%-19.79%, and 77.53%-104.42% with RSDs 0.92%-18.65%, respectively. Lastly, this quantitative method was applied to determine the SCFA concentrations and compositions in forty fecal samples from a group of study subjects participating in an obesity prevention trial, and a broad range of concentrations was noted for the detected SCFAs., Competing Interests: Declaration of Competing Interest The authors report no declarations of interest., (Copyright © 2021 Elsevier B.V.

Objective: This study sought to understand the association of mental health-related quality of life (MHRQoL) and nutritional status (food security status and malnutrition risk), with diet quality among female survivors of breast cancer., Method: This pilot cross-sectional study utilized self-report survey data from the RAND-36, the USDA 2-item food insecurity screen, the Malnutrition Screening Tool (MST), and the Diet History Questionnaire II (DHQII)/Health Eating Index 2015 (HEI). Participants self-selected participation after being identified through an academic medical center cancer registry and contact through mailed recruitment letters and flyers posted in oncology clinics. Emotional well-being and social functioning composite scores of the RAND-36 were used to characterize MHRQoL. Correlational and regression analyses were performed to assess the association of diet quality, nutritional status, and MHRQoL., Results: The majority of participants (n = 90) were non-Hispanic white (90%), average age of 71.3 ± 8.1 years, and an average body mass index (BMI) of 28.2 ± 6.6. Four of the 90 participants (4.4%) scored at risk for food insecurity. Linear regression indicated that social functioning composite scores were positively associated with HEI scores (β = 0.11, SE = 0.53, p = 0.03). Controlling for demographic characteristics, education level (β = 5.25, SE = 2.25, p = 0.02) was positively associated with HEI scores., Conclusion: Diet quality and MHRQoL were associated among breast cancer survivors, with education level also being associated with diet quality. These results can be used to aid targeted nutrition counseling and mental health interventions to address the nutritional vulnerabilities among female breast cancer survivors, particularly among older cancer survivors.

Objective: To identify predictors associated with specific family meal practices and weight talk among patients participating in weight management programs (WMPs) and weight loss surgery (WLS) and their children., Design: Cross-sectional survey., Setting: Two US weight management centers., Participants: 259 patients (aged ≥ 18 years) in either WMP (n = 101) or WLS (n = 158) and residing with a child (aged 2-18 years) MAIN OUTCOME MEASURE(S): Dependent variables: family meal practices (Project EAT) and weight talk (investigator-created). Covariates: family communication (Family Communication Scale), family discouragement for making eating habit change (Social Support for Eating Habits Survey), child age, sex, and perceived weight status, and WMP or WLS participation., Analysis: Binomial and ordinal regression models determined the odds of engaging in specific family meal practices and weight talk, including covariates., Results: Patients had increased odds of engaging in family dinners if they reported lower family discouragement (P = .003) and had younger children (P < .001), and increased odds of engaging in family breakfast if they had higher family communication (P = .002) and younger children (P = .020). Patients had increased odds of talking about their child's weight if their child was perceived to have an overweight/obese weight status (P < .001). Patients with older children had increased odds of talking about their weight with their child (P = .021)., Conclusions and Implications: Additional research assessing the family meal practices and weight talk in the families of adults pursuing weight loss could yield important evidence that could lead to improved patient outcomes, and safely promote healthy behaviors and prevention of obesity in children., (Published by Elsevier Inc.)

Cancer-related malnutrition is associated with poor health outcomes, including decreased tolerance to cancer therapy, greater treatment toxicities, and increased mortality. Medical nutrition therapy (MNT) optimizes clinical outcomes, yet registered dietitian nutritionists (RDNs), the healthcare professionals specifically trained in MNT, are not routinely employed in outpatient cancer centers where over 90% of all cancer patients are treated. The objective of this study was to evaluate RDN staffing patterns, nutrition services provided in ambulatory oncology settings, malnutrition screening practices, and referral and reimbursement practices across the nation in outpatient cancer centers. An online questionnaire was developed by the Oncology Nutrition Dietetic Practice Group (ON DPG) of the Academy of Nutrition and Dietetics and distributed via the ON DPG electronic mailing list. Complete data were summarized for 215 cancer centers. The mean RDN full-time equivalent (FTE) for all centers was 1.7 ± 2.0. After stratifying by type of center, National Cancer Institute-Designated Cancer Centers (NCI CCs) employed a mean of 3.1 ± 3.0 RDN FTEs compared to 1.3 ± 1.4 amongst non-NCI CCs. The RDN-to-patient ratio, based on reported analytic cases, was 1 : 2,308. Per day, RDNs evaluated and counseled an average of 7.4 ± 4.3 oncology patients. Approximately half (53.1%) of the centers screened for malnutrition, and 64.9% of these facilities used a validated malnutrition screening tool. The majority (76.8%) of centers do not bill for nutrition services. This is the first national study to evaluate RDN staffing patterns, provider-to-patient ratios, and reimbursement practices in outpatient cancer centers. These data indicate there is a significant gap in RDN access for oncology patients in need of nutritional care., Competing Interests: The authors have no conflicts of interest., (Copyright © 2019 Elaine B.

Current dietary intakes of North Americans are inconsistent with the Dietary Guidelines for Americans. This occurs in the context of a food system that precludes healthy foods as the default choices. To develop a food system that is both healthy and sustainable requires innovation. This science advisory from the American Heart Association describes both innovative approaches to developing a healthy and sustainable food system and the current evidence base for the associations between these approaches and positive changes in dietary behaviors, dietary intakes, and when available, health outcomes. Innovation can occur through policy, private sector, public health, medical, community, or individual-level approaches and could ignite and further public-private partnerships. New product innovations, reformulations, taxes, incentives, product placement/choice architecture, innovative marketing practices, menu and product labeling, worksite wellness initiatives, community campaigns, nutrition prescriptions, mobile health technologies, and gaming offer potential benefits. Some innovations have been observed to increase the purchasing of healthy foods or have increased diversity in food choices, but there remains limited evidence linking these innovations with health outcomes. The demonstration of evidence-based improvements in health outcomes is challenging for any preventive interventions, especially those related to diet, because of competing lifestyle and environmental risk factors that are difficult to quantify. A key next step in creating a healthier and more sustainable food system is to build innovative system-level approaches that improve individual behaviors, strengthen industry and community efforts, and align policies with evidence-based recommendations. To enable healthier food choices and favorably impact cardiovascular health, immediate action is needed to promote favorable innovation at all levels of the food system.

We tested whether lifelong modification of vitamin D signaling can alter the progression of early prostate carcinogenesis in studies using mice that develop high-grade prostatic intraepithelial neoplasia that is similar to humans. Two tissue-limited models showed that prostate vitamin D receptor (VDR) loss increased prostate carcinogenesis. In another study, we fed diets with three vitamin D 3 levels (inadequate = 25 IU/kg diet, adequate for bone health = 150 IU/kg, or high = 1,000 IU/kg) and two calcium levels (adequate for bone health = 0.5% and high = 1.5%). Dietary vitamin D caused a dose-dependent increase in serum 25-hydroxyvitamin D levels and a reduction in the percentage of mice with adenocarcinoma but did not improve bone mass. In contrast, high calcium suppressed serum 1,25-dihydroxyvitamin D levels and improved bone mass but increased the incidence of adenocarcinoma. Analysis of the VDR cistrome in RWPE1 prostate epithelial cells revealed vitamin D-mediated regulation of multiple cancer-relevant pathways. Our data support the hypothesis that the loss of vitamin D signaling accelerates the early stages of prostate carcinogenesis, and our results suggest that different dietary requirements may be needed to support prostate health or maximize bone mass. SIGNIFICANCE: This work shows that disrupting vitamin D signaling through diet or genetic deletion increases early prostate carcinogenesis through multiple pathways. Higher-diet vitamin D levels are needed for cancer than bone., (©2019 American Association for Cancer Research.)

Selective eating is common in children with autism spectrum disorder (ASD), but it is not yet well understood. The objectives of this study were to examine a new definition of selective eating, compare behavioral measures between children with ASD and selective eating and those without selective eating, and determine relationships among behavioral measures and measures of selective eating. Participants were assigned to groups on the basis of number of foods eaten compared with a population-based sample. Results of one-way multivariate analysis of variance indicated no overall effect of group for challenging behaviors, sensory reactivity, or repetitive behaviors. Between-participant tests indicated that scores for compulsive behaviors were significantly lower (p = .036) for the selective eating group. Correlations were moderately strong among variables relating to food intake and behavioral variables, but were not significant between selective eating and behavioral variables. Further research is needed to validate the definition of selective eating and to identify targets for intervention., (Copyright © 2015 by the American Occupational Therapy Association, Inc.)

Background: Obese youth demonstrate the same obesity-associated morbidities observed in obese adults, including poor cardiorespiratory fitness, poor quality of life, and reports of musculoskeletal pain. The purposes of this study were to compare the prevalence of cardiovascular risk factors and evaluate the odds of metabolic syndrome in obese youth based on measures of cardiorespiratory fitness, quality of life, and pain., Methods: A medical chart review of 183 obese youth in a medical weight management program was conducted. Measures of cardiovascular risk and metabolic syndrome were recorded. Groups were categorized based on Progressive Aerobic Cardiovascular Endurance Run (PACER) score, Pediatric Quality of Life (PedsQL)-Physical Function score, PedsQL-Psychosocial Health score, and reports of musculoskeletal pain. Statistical analysis included independent t-tests, Mann-Whitney U-test, chi-squared test, and logistic regression., Results: Thirty-three percent of the entire sample had C-reactive protein (CRP) levels >3.0 mg/dL and 30% were categorized as having metabolic syndrome. Patients with lower PACER scores demonstrated a greater prevalence of CRP levels >3.0 mg/dL versus those with higher PACER scores (45% vs. 12%; P=0.01). There were no other differences in the prevalence of cardiovascular risk factors or metabolic syndrome when categorized by PACER, PedsQL, or pain. Those with CRP levels >3.0 mg/dL demonstrated increased odds of metabolic syndrome-[odds (95% confidence interval, CI): 4.93 (1.24-19.61); P=0.02]., Conclusions: Overall, results do not show differences in cardiovascular risk in obese youth when categorized by PACER, PedsQL, or reports of MSK pain. Elevated CRP may be a useful predictor of metabolic syndrome in obese youth and warrants further investigation.
