RESUMEN
Obesity stands out as a primary risk factor for diabetes. Attaining healthy weight loss, especially reducing body fat, is important in managing prediabetes and preventing progression to full diabetes and its co-morbidities. This study examined the effects of personalized nutrition therapy (PNT) combined with continuous glucose monitoring (CGM) on body weight and composition in individuals with prediabetes. A total of 30 individuals with prediabetes who were overweight or obese were assigned randomly to either the treatment, observed CGM data plus PNT, or the control group which was blinded to their blood glucose results throughout the study. Both groups were provided with dietary recommendations for calorie intake and macronutrient distribution, coupled with personalized goal setting for glucose control and healthy eating, without any specific emphasis on weight reduction or changes in physical activity. Regular visits were scheduled every 10 days to perform measurements and replace CGMs. Data were analyzed using General Linear Model with repeated measures. Over the 30-day follow-up period, both groups experienced significant reductions in weight and fat mass. The treatment group exhibited two-fold greater reductions in both weight and fat mass, a significant decrease in carbohydrate intake, and a significant increase in time spent on physical activitycompared to the control group. In addition, compliance was notably higher in the treatment group. These findings indicate that overweight or obese individuals with prediabetes can achieve weight loss and improved body composition through personalized education for glucose control, without exclusively emphasizing weight loss as the primary objective. Additionally, the real-time feedback provided by CGM enhances these improvements.

PURPOSE OF REVIEW: To analyze how social and structural determinants of health and social injustice impact the risk of obesity, its treatment and treatment outcomes, and to explore the implications for prevention and future treatment interventions. RECENT FINDINGS: Racial and ethnic minorities, such as non-Hispanic Black adults and Hispanic adults, and adults with a low socioeconomic status have a greater risk of obesity than non-Hispanic white adults and adults with a high socioeconomic status. The underlying causes of obesity disparities include obesogenic neighborhood environments, inequities in access to obesity treatment, and lack of access to affordable nutrient-dense foods. Experts have called for interventions that address the social and structural determinants of obesity disparities. Population-based interventions that focus on improving neighborhood conditions, discouraging the consumption of unhealthy foods and beverages, expanding access to obesity treatment, and ensuring equitable access to fruits and vegetables have been proven to be effective. There is a growing body of evidence that shows the relationship between social and structural determinants of health and injustice on disparities in obesity among racial and ethnic minorities and individuals with a low SES. Population-based, equity-focused interventions that address the underlying causes of obesity disparities are needed to reduce obesity disparities and improve the health outcomes of minoritized and marginalized groups.

(1) Background: Independently owned restaurants (IORs) are prevalent in under-resourced racial and ethnic minority communities in the US and present a unique setting for public health nutrition interventions. (2) Methods: We conducted 14 in-depth interviews with IOR owners in Baltimore about their perceptions of healthy food, and customers' acceptance of healthier menus and cooking methods and concurrent observations of the availability of healthy options on their menus. Qualitative data were coded and analyzed using ATLAS.ti. Observations were analyzed with statistical analysis performed in R. (3) Results: Owners perceived non-fried options, lean proteins, and plant-based meals as healthy. While open to using healthier cooking fats, they had mixed feelings about reducing salt, adopting non-frying methods for cooking, and adding vegetables and whole grains to the menu, and were reluctant to reduce sugar in recipes and beverages. Only 17.5% of 1019 foods and 27.6% of 174 beverages in these IORs were healthy, with no significant differences in the healthfulness of restaurant offerings within low-healthy-food-access/low-income neighborhoods and those outside. (4) Conclusion: Healthy options are generally scarce in Baltimore's IORs. Insights from owners inform future interventions to tailor healthy menu offerings that are well-received by customers and feasible for implementation.

BACKGROUND: Upstream socioeconomic circumstances including food insecurity and food desert are important drivers of community-level health disparities in cardiovascular mortality let alone traditional risk factors. The study assessed the association between differences in food environment quality and cardiovascular mortality in US adults. DESIGN: Retrospective analysis of the association between cardiovascular mortality among US adults aged 45 and above and food environment quality, measured as the food environment index (FEI), in 2615 US counties. FEI was measured by equal weights of food insecurity (limited access to a reliable food source) and food desert (limited access to healthy food), ranging from 0 (worst) to 10 (best). Age-adjusted cardiovascular mortality rates per 100,000 adults aged 45 and above in the calendar year 2017-2019. County-level association between CVD mortality rate and FEI was modeled using generalized linear regression. Data were weighted using county population. RESULT: Median CVD deaths per 100,000 population were 645.4 (IQR 561.5, 747.0) among adults aged 45 years and above across US counties in 2017-2019. About 12.8% (IQR 10.7%, 15.1%) of residents were food insecure and 6.3% (IQR 3.6%, 9.9%) were living in food desert areas. Comparing counties by FEI quartiles, the CVD mortality rate was higher in the least healthy FE counties (704.3 vs 598.6 deaths per 100,000 population) compared to the healthiest FE counties. One unit increase in FEI was associated with - 12.95 CVD deaths/100,000 population. In the subgroup analysis of counties with higher income inequality, the healthiest food environment was associated with 46.4 lower CVD deaths/100,000 population than the least healthy food environment. One unit increase in FEI in counties with higher income inequality was associated with a fivefold decrease in CVD mortality difference in African American counties (- 18.4 deaths/100,000 population) when compared to non-African American counties (- 3.63 deaths/100,000 population). CONCLUSION: In this retrospective multi-county study in the USA, a higher food environment index was significantly associated with lower cardiovascular mortality.

Diabetes is associated with an increased risk of mental disorders, including depression, anxiety, and cognitive decline. Mental disorders can also contribute to the development of diabetes through various mechanisms including increased stress, poor self-care behaviors, and adverse effects on glucose metabolism. Consequently, individuals suffering from either of these conditions frequently experience comorbidity with the other. Nutrition plays an important role in both diabetes and mental health disorders including depression and anxiety. Deficiencies in specific nutrients such as omega-3 fatty acids, vitamin D, B vitamins, zinc, chromium, magnesium, and selenium have been implicated in the pathogenesis of both diabetes and mental disorders. While the impact of nutrition on the progression and control of diabetes and mental disorders is broadly acknowledged, there is a notable knowledge gap concerning the implications of distinct nutrients in preventing and mitigating symptoms of both conditions when they coexist. The aim of this study was to examine the role of nutrition in improving glucose homeostasis and promoting mental well-being among individuals with diabetes. Further, we evaluated the preventive or delaying effects of key nutrients on the simultaneous manifestation of these conditions when one of them is present. Our findings indicated that the use of personalized dietary interventions and targeted nutrient supplementation can improve metabolic and mental health outcomes in patients with type 2 diabetes.
RESUMEN
Objective: Identifying the food sources contributing most to total energy percentage, macronutrients, vitamin and mineral consumption among college freshmen, and whether sex played a role. Participants: First-year undergraduate students (N = 269). Methods: Diet was assessed using a DHQ-III and estimated with food source composition tables. Nutrient intakes were expressed as a percentage of total dietary intakes for each food category. Mann-Whitney U tests were used to determine the differences between the two sexes for each food category. Results: A significant proportion of energy and nutrients is contributed by certain food categories, such as grain products, meat, poultry, fish; however, other less desirable sources of energy and nutrient are also identified, including sugary and sports drinks. Among female students, a greater portion of nutritional intakes came from healthier choices. Conclusions: A majority of total energy intake comes from food categories that are energy-dense but also provide essential nutrients.
RESUMEN
BACKGROUND: In clinical research, there has been a call to move beyond individual psychosocial factors towards identifying cultural and social factors that inform mental health. Similar calls have been made in the eating disorders (ED) field underscoring the need to understand larger sociocultural influences on EDs. Discrimination is a social stressor that may influence mental health in similar ways to traumatic or adverse childhood experiences (ACEs). Given the high rates of EDs and discrimination among marginalized groups, it is vital to understand the role of discrimination and ACEs as predictors of ED symptoms in these populations. The aim of this study is to examine how perceived discrimination predicts ED pathology when statistically adjusting for gender, race, and ACEs. METHODS: The diverse study sample consisted of 331 undergraduate students from a longitudinal cohort study (ages 18-24; 66% female; 35% White/non-Hispanic). Participants completed measures of everyday discrimination, ACEs, and ED pathology. RESULTS: Following adjustment for multiple statistical comparisons, the frequency of daily discrimination predicted all ED symptoms above and beyond history of ACEs. In follow-up analyses, number of reasons for discrimination predicted cognitive restraint and purging. Differences in ED symptomatology were found based on the reason for discrimination, gender, and race. Specifically, those who experienced weight discrimination endorsed higher scores on all ED symptoms, and those experiencing gender discrimination endorsed higher body dissatisfaction, cognitive restraint, and restriction. People of color endorsed higher restriction, while female participants endorsed higher scores on all ED symptom with the exception of cognitive restraint. CONCLUSION: Discrimination is a salient risk factor for ED symptoms even when accounting for individuals' history of ACEs. Future research should utilize an intersectional approach to examine how perceived discrimination affects ED pathology over time. (Word count: 234).
Adverse childhood experiences (ACEs) increase risk for eating disorders (EDs). Discrimination based on race, gender, and gender and sexual identity is also linked to ED behaviors. This paper examined whether discrimination impacted ED behaviors when ACEs were considered to understand how they both might play a role in risk for EDs. Findings suggest that experiences of discrimination may have a greater impact on eating disorder symptoms in college students than a history of ACEs. More research is needed to understand the negative impacts of discrimination on eating disorders, in addition to history of trauma. Clinicians should attend to the ways discrimination may impact their clients' eating disorder behaviors, and whether individuals experience bias or discrimination when seeking eating disorder treatment.
RESUMEN
PURPOSE: To evaluate associations of ghrelin, glucagon-like peptide 1 (GLP-1), and peptide YY 3-36 (PYY3-36) with weight change after bariatric arterial embolization (BAE). MATERIALS AND METHODS: Subgroup analysis of data collected during the BEAT Obesity Trial involving 7 participants with BMI > 40 who were embolized with 300- to 500-µm Embosphere Microspheres. Three participants were characterized as "responders" (top tertile of weight loss at each visit) and 4 as "non-responders" (bottom tertile of weight loss at each visit). Mean ± standard deviation participant age was 44 ± 11 years, and 6 of 7 participants were women. Participants were evaluated at baseline, 2 weeks, and 1, 3, 6, and 12 months after BAE. After fasting, participants consumed a mixed meal test at each visit; blood samples were collected at 0, 15, 30, 60, 120, 180, and 240 min. Study outcome measures were changes in weight from baseline and plasma serum hormone levels. RESULTS: Percentage change in ghrelin decreased significantly in non-responders at 60 and 120 min at 1 and 12 months (estimated difference between 60 vs. 0 min at 1 month: 69% [95% CI - 126%, - 13%]; estimated difference between 120 vs. 0 min at 12 months: - 131% (95% CI - 239%, - 23%]). Responders had significantly lower ghrelin and greater weight loss than non-responders at 6 and 12 months. GLP-1 and PYY3-36 levels did not differ between groups. CONCLUSION: Participants with consistent weight loss throughout follow-up had lower ghrelin than non-responders, supporting decreased ghrelin as a mechanism underlying BAE-induced weight loss. LEVEL OF EVIDENCE I: High-quality randomized trial or prospective study; testing of previously developed diagnostic criteria on consecutive patients; sensible costs and alternatives; values obtained from many studies with multiway sensitivity analyses; systematic review of Level I RCTs and Level I studies.

Objective: To evaluate dietary and physical activity behavior in relation to loneliness among college students. Participants: Three-hundred forty-six incoming first-year students in Fall 2019 at a large state University in the US. Methods: Students completed online surveys in Fall 2019. Multivariable regression analyses were used to model associations of health behaviors with loneliness, adjusting for gender and body mass index (BMI). Results: Two-hundred sixty-four students were included in this analysis. Students in loneliness score ranges of 4-6 and 7-9 have higher fat diet than students in score range of 10-12 (p = .007). Sedentary (19.2%) and low active (53.8%) behaviors were more frequent in students reporting high loneliness than those reporting low loneliness (13.8%, 36.7%, respectively) (p = .006). Conclusions: In this sample of college students, loneliness was related to altered diet quality and physical inactivity. Interventions to reduce loneliness may have a positive effect on health promotion in this population.
RESUMEN
OBJECTIVE: We examined the prevalence of elevated blood pressure (BP) and hypertension among 390 primary school children of different socioeconomic status (SES) in two urban settings in Kenya and explored the association between children's BP status and their sociodemographic characteristics, dietary behaviours and overweight/obesity status. METHODS: Children's BP and anthropometric measurements were taken and parents, with the help of their children, completed questionnaires on the children's dietary behaviours. An average of three BP readings was used to calculate BP percentiles by age, sex and height. BMI-for-age z-scores, waist-circumference-to-height ratio and the sum of skinfold measures were calculated. We utilized prevalence ratio analysis to examine the association between BP and sociodemographic characteristics, dietary behaviours and overweight/obesity. RESULTS: About 9% of the school children had elevated BP and 33% had stage 1 hypertension. Among overweight children, the proportion of children with elevated BP was 1.85-fold greater and the proportion of children with hypertension was 1.83-fold greater compared with children with healthy body weight. Similar patterns of significant associations were seen among obese children, children with central obesity and children with high total skinfold values. The proportion of children with hypertension was 1.42-fold greater among children with high frequency of consumption of chips/crisps compared with children with lower frequency of consumption. CONCLUSION: These results increase our understanding BP patterns and determinants among school children in Kenya and can help inform noncommunicable disease prevention efforts.

OBJECTIVE: This study examined the effects of overweight/obesity on mortality and morbidity outcomes and the disparities, time trends, and projected future obesity health burden in China. METHODS: Cohort studies that were conducted in China and published in English or Chinese between January 1, 1995, and July 31, 2021, were systematically searched. This study focused on overweight/obesity, type 2 diabetes mellitus (T2DM), hypertension, cardiovascular diseases, metabolic syndrome, cancers, and chronic kidney disease. RESULTS: A total of 31 cohorts and 50 cohort studies reporting on mortality (n = 20) and morbidities (n = 30) associated with obesity met study inclusion criteria. Overall, BMI was nonlinearly (U-shaped) associated with all-cause mortality and linearly associated with risks of T2DM, cardiovascular diseases, hypertension, cancer, metabolic syndrome, and chronic kidney disease. In 2018, among adults, the prevalence of overweight/obesity, hypertension, and T2DM was 51.2%, 27.5%, and 12.4%, respectively. Their future projected prevalence would be 70.5%, 35.4%, and 18.5% in 2030, respectively. The projected number of adults having these conditions would be 810.65 million, 416.47 million, and 217.64 million, respectively. The urban-rural disparity in overweight/obesity prevalence was projected to shrink and then reverse over time. CONCLUSIONS: The current health burden of obesity in China is high and it will sharply increase in coming years and affect population groups differently. China needs to implement vigorous interventions for obesity prevention and treatment.

Tibetans' life expectancy lags behind China's average. Obesity and noncommunicable diseases (NCDs) contribute to health disparity, but NCD patterns among Tibetans are unknown. To examine the prevalence, management, and associated factors for obesity, hypertension, and diabetes among Tibetans, compared with China's average, we systematically searched PubMed and China National Knowledge Infrastructure databases for studies between January 2010 and April 2021. Thirty-nine studies were included for systematic review, among thirty-seven that qualified for meta-analysis, with 115,403 participants. Pooled prevalence was 47.9% (95% CI 38.0-57.8) for overweight/obesity among adults (BMI ≥ 24 kg/m2) and 15.4% (13.7-17.2) among children using Chinese criteria, which are lower than the national rates of 51.2% and 19.0%, respectively. The estimate for hypertension (31.4% [27.1-35.7]) exceeded China's average (27.5%), while diabetes (7.5% [5.2-9.8]) was lower than average (11.9%). Men had a higher prevalence of the three conditions than women. Residents in urban areas, rural areas, and Buddhist institutes had monotonically decreased prevalence in hypertension and diabetes. Awareness, treatment, and control rates for hypertension and diabetes were lower than China's average. Urban residence and high altitude were consistent risk factors for hypertension. Limited studies investigated factors for diabetes, yet none exist for obesity. Tibetans have high burdens of obesity and hypertension. Representative and longitudinal studies are needed for tailored interventions. There are considerable variations in study design, study sample selection, and data-analysis methods, as well as estimates of reviewed studies.

OBJECTIVE: Examine the proportion of students with rapid firearm access and associations with recent alcohol and marijuana use. PARTICIPANTS: Cross-sectional data from college freshmen (n = 183) in 2020 who participated in the Mason: Health Starts Here study. METHODS: Using logistic regression, associations were examined between past 30-day substance use and access to firearms within 15-min. RESULTS: More than 10% of students could rapidly access a firearm, 53% of whom were current binge drinkers, compared to 13% of those who could not rapidly access firearms. Non-Hispanic White students (AOR = 4.1, 95%CI = 1.3,12.7) and past 30-day binge drinkers (AOR = 6.4, 95%CI = 2.1,19.7) had greater odds of having rapid firearm access. Age, sex, and past 30-day marijuana use were not associated with rapid access. CONCLUSIONS: A notable proportion of students had rapid firearm access, which was strongly associated with recent binge drinking. Campus prevention programs should consider how their alcohol and firearm policies could be enhanced to prevent violence/self-harm.
RESUMEN
AIMS: The primary objective of this study is to conduct a systematic review of existing literature on the association between food insecurity and housing instability with CVD and its subtypes-related outcomes. Summarizing the comprehensive evidence for independent/interchangeable relationship of food and housing instability with CVD outcomes may inform specific interventions strategies to reduce CVD-risk. DATA SYNTHESIS: The search focused on English-language articles in PubMed/Medline, from January 1, 2010, to June 1, 2021, with restriction to the US adult population. We included studies estimating the association between food insecurity or/and housing instability(exposure) and CVD-subtypes-related health outcomes (outcome). The study methodological quality was assessed using the Study Quality Assessment Tools (SQAT). Nineteen studies met eligibility criteria, consisted of 15 cross-sectional and 4 cohort studies. Of total studies, 7 examined housing instability, 11 studies focused on food insecurity, and one examined both. Food insecurity/housing instability was associated with increased overall CVD-mortality rate and greater healthcare cost utilization, while evidence were mixed for hospital readmission rate. By subtype, stroke mortality was greater with food insecurity but not with housing instability. The likelihood of myocardial infarction, coronary heart disease, and congestive heart failure was greater with food insecurity. Although mortality with MI was higher with housing instability, readmission and surgical procedure rates were significantly lower than housing stable adults. CONCLUSION: Findings from this review suggest an urgent need to test the impact of screening for food and housing insecurities, referral services, and community engagement for CV health, within clinical and public health settings.

Eating disorders (EDs) and posttraumatic stress disorder (PTSD) commonly co-occur, but the mechanisms driving this co-occurrence are not well understood. The current study explored the relationships between symptoms of ED and PTSD in a sample of male and female undergraduate students in order to identify pathways that may maintain the comorbidity. Network analysis was conducted in a sample of 344 first-year undergraduates to visualize partial correlations between each symptom in the comorbidity. Core symptoms, bridge symptoms, and direct pathways between ED and PTSD symptoms were identified. The PTSD symptoms negative emotions (strength = 1.13) and negative beliefs (strength = 1.11) were the strongest symptoms in the network. The strongest bridge nodes were the ED symptoms restriction (bridge strength = 3.32) and binge eating (bridge strength = 2.63). The strongest edges between ED and PTSD nodes were between binge eating and concentration (part r = .16), restriction and sleep (part r = .14), and binge eating and positive emotions (part r = .11). Findings suggest that PTSD symptoms related to negative alterations in cognitions and mood may be highly influential in the ED-PTSD network due to their relatedness to all other symptoms. The pathway between binge eating and inability to experience positive emotions suggest that the comorbidity may be partially maintained through an affect regulation function of binge eating.

BACKGROUND: Text-messaging interventions can reach many individuals across a range of socioeconomic groups, at a low cost. Few randomized controlled trials (RCTs) of text-messaging weight loss interventions have been conducted in United States. METHODS: From September of 2016 to September of 2018, we conducted a two-parallel group, superiority, RCT of a 16-week text-messaging, weight loss intervention in Baltimore, Maryland, in overweight and obese adults younger than 71, who were able to receive text-messages. Our objective was to assess the effect of receiving the message content only (in printed documents distributed at baseline and week 8), versus receiving messages via short messaging service (SMS) on weight loss (primary outcome), body mass index, perceived exercise benefits and barriers, self-efficacy, and physical activity (PA). The random allocation sequence was equally balanced intervention groups by gender and age groups. Participants were randomized after the baseline assessment. Then, participants and most study staff were unblinded. Follow-up assessments were conducted at 8-, 16-, and 42-week post randomization. We performed intention-to-treat analysis using mixed linear regression models. RESULTS: Of the 155 adults randomized (printed messages =77, SMS =78), 87.1% were women, 53.5% were African Americans, and 93.5% non-Hispanic. Participants who completed at least one follow-up assessment were included in regression analyses (n=145, printed messages =74, SMS =71). Compared to baseline, at the 42-week assessment, the average percent weight loss was 1.23 for the SMS group (P=0.006) and 0.86 for the printed messages group (P=0.047). Both groups experienced small reductions in weight (printed messages: -0.96 kg, P=0.022; SMS: -1.19 kg, P=0.006), BMI (printed messages: -0.32, P=0.035; SMS: -0.52, P=0.002), and percent energy from fat consumption (printed messages: -1.43, P=0.021; SMS: -2.14, P≤0.001). No statistically significant between groups differences were detected for any of the study outcomes. SMS response rates were not statistically significantly associated with study outcomes. No adverse events were reported. CONCLUSIONS: A semi-tailored SMS weight loss intervention among overweight and obese adults was not statistically superior in efficacy to paper-based messaging. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04506996.
RESUMEN
OBJECTIVE: The objective of the study was to evaluate how well college students meet U.S. dietary guidelines by examining the mean intakes of nutrients to limit (sodium, sugar, refined grains, and saturated fat), and what factors lead to exceeding the dietary recommendations. PARTICIPANTS: Participants were first-year undergraduate students (N = 269). METHODS: Diet was assessed using a DHQ-III and estimated with food source composition tables. Multivariable logistic regression analysis was used to model variables associated with exceeding the recommendations. One-sample t-tests were performed to compare the cohort with national intakes. RESULTS: One-third met added sugar guidelines; only 4% met daily refined grains requirements, Fewer than half met saturated fat guidelines, and slightly over half met recommended sodium guidelines. Level of physical activity, race/ethnicity, and living on campus were the important predictors for exceeding recommended intakes. CONCLUSIONS: Most students do not adhere to the U.S. dietary guidelines for nutrients to limit.
RESUMEN
Low testosterone may be a novel risk factor for prediabetes. We assessed the associations between prediabetes and total serum testosterone (TT), and whether the associations were modified by population characteristics. The data from 5330 adults aged ≥ 20 years, who participated in the 2011−2016 National Health and Nutrition Examination Survey in the United States, were used. Prediabetes was based on fasting plasma glucose, HbA1c, or OGTT. Sociodemographic, obesity, co-morbidities, and lifestyle factors were included in logistic regression models. A dose-response relationship was found between prediabetes and the testosterone quartiles. The odds ratio (OR and 95% CI) for prediabetes across the quartiles of TT were: 1.00, 0.68 (0.50−0.92), 0.51 (0.36−0.72), and 0.48 (0.34−0.70) in men; and 1.00, 1.06 (0.81−1.40), 0.81 (0.61−1.06), and 0.68 (0.49−0.93) in women. The results changed marginally if the models were adjusted for additional variables such as BMI. The subgroup analyses showed differences in the association, which was stronger in some groups (for men: age < 50, white and black, overweight/obese, adequate physical activity, never-smoking; and for women: age ≥ 50, black). A higher testosterone level was associated with a lower risk of prediabetes among US adults. The strength of the association varied by population characteristics, weight status, gender, and lifestyle factors.

Young adults typically gain more dietary autonomy as they start college, though this can also present nutritional challenges; however, research on the generalizability of their dietary intake data is scarce. To address this representativeness concern, we compared food and nutrient intakes reported by college freshmen attending a large, diverse university to an age-matched sample from the National Health and Nutrition Examination Survey (NHANES). We studied 269 students 18-24 years old recruited through the Mason: Health Start Here (HSH) study, a population-based cohort study of college students. Diet was assessed using a diet history questionnaire (DHQ-III) and estimated with food source composition tables. The NHANES sample of 835 adults was the reference dataset. Reported dietary intakes were weighted and compared with national intakes via t-tests. We observed comparable energy, carbohydrate, fat, and protein intakes in both groups; however, the HSH cohort reported a higher density intake of most micronutrients than the NHANES sample. Differences between these samples in intake, mode of dietary assessment administration, and reactivity may help explain the differences detected. These results demonstrate that when appropriately contextualized in terms of methodology and potential sources of bias, single college studies can be useful for understanding nutrition in young adults more broadly.
