ABSTRACT
OBJECTIVE: To examine awareness, information-seeking, and use of MyPlate among US adults with young children. DESIGN: Secondary analysis of cross-sectional data from the 2015-2018 National Health and Nutrition Examination Survey (NHANES). PARTICIPANTS: US adults aged 18-45 years with children ≤5 years. VARIABLES MEASURED: Adults reported sociodemographic characteristics and whether they had heard of MyPlate, looked online for MyPlate information, or tried to follow the MyPlate plan. ANALYSIS: Logistic regression models estimated MyPlate awareness, information-seeking, and use by sociodemographic characteristics. Analyses were weighted to represent adults with young children nationally. RESULTS: Twenty-nine percent of US adults with young children were aware of MyPlate. MyPlate awareness was lower among men, racial/ethnic minorities, adults with less education, adults who speak a language other than English, and SNAP/WIC recipients. Among those who knew of MyPlate, 39% sought MyPlate information online, and 33% had tried to use the MyPlate plan. Men were less likely to look online for or follow the MyPlate plan than women. Mexican-American adults and WIC recipients were more likely to have tried to follow the MyPlate plan. CONCLUSIONS: MyPlate is an underutilized resource among families with young children. Efforts are needed to disseminate and encourage the use of MyPlate, particularly among marginalized groups.
ABSTRACT
OBJECTIVE: This study examined college students' food security status, Choose MyPlate familiarity, and confidence in preparing healthy meals using food pantry ingredients. METHODS: A sample of 354 student users of a college food pantry in the US southeastern region were surveyed before using the food pantry for the first time. RESULTS: Of the respondents, 81.3% were food insecure, and 47% of the overall sample experienced very low food security. About one-third (37.3%) recognized MyPlate; of those, 89.4% stated intention to use MyPlate knowledge making pantry selections. Students familiar with MyPlate (P = 0.003) and intending to use MyPlate when making food selections (P = 0.02) exhibited greater confidence. Differences were not observed on the basis of food security status. CONCLUSIONS AND IMPLICATIONS: These findings suggest that familiarity with simple nutritional guidelines such as MyPlate may improve students' intended food pantry selections and healthy meal selection confidence.
ABSTRACT
This paper describes the 30-year evolution of Supplemental Nutrition Assistance Program-Education (SNAP-Ed) to provide evidence to support our perspective that SNAP-Ed has earned its position as a pillar of the public health infrastructure in the US. Legislatively designated as a nutrition education and obesity prevention program, its focus is the nearly 90 million Americans with limited income. This audience experiences ongoing health disparities and is disproportionately affected by public health crises. The SNAP-Ed program works to reduce nutrition-related health disparities at all levels of the Social-Ecological Model, follows a robust evaluation framework, and leverages strong partnerships between state-based practitioners, state agencies, and the US Department of Agriculture. The expansion of SNAP-Ed would enable the program to reach more Americans so that our nation can end hunger and reduce diet-related health disparities.

BACKGROUND: PortionSize offers real-time feedback on dietary intake, including intake of MyPlate food groups but requires further evaluation on a larger sample in a laboratory-based setting. MyFitnessPal (MFP) is a commonly used commercial dietary assessment application, and to our knowledge, no known studies have evaluated MFP in a laboratory setting. OBJECTIVES: The overall objective was to test the validity of PortionSize and MFP to accurately measure intake compared with that of weighed food (WB) and to compare error between applications. A secondary objective was to test usability, satisfaction, and user preference between applications. METHODS: This randomized crossover study was completed between February and October 2021. Participants (N = 43) used both applications to estimate intake in a laboratory setting. Participants were provided with a preweighed plated meal and plated leftovers. Two 1-sided t tests assessed equivalence (±21% bounds) between simulated intake from PortionSize and WB, and MFP and WB. The primary outcome was energy intake, and secondary outcome measures were portion size (in grams), food groups, and other nutrients. Differences in relative absolute error, usability, satisfaction, and user preference between applications were evaluated using dependent samples t tests. Cohen d assessed effect size. RESULTS: For PortionSize, energy and portion size were underestimated by 13.3% and 14.0%, respectively, and were not equivalent to WB. For MFP, energy was overestimated by 7.0%, and equivalent to WB (P = 0.04). Relative absolute error for energy did not differ between applications. For PortionSize, Cohen d was small (<0.2) for fruits, grains, protein foods, and specific nutrients. No differences were seen with usability, and the only difference for satisfaction was that participants found it easier to use MFP to find foods consumed (P = 0.019), and participants preferred using MFP (P = 0.014). CONCLUSIONS: PortionSize requires further updates to improve energy estimates and usability but demonstrates clinical utility for tracking food group and nutrient intake. PortionSize did not outperform MFP for measuring energy intake. CLINICAL TRIAL REGISTRY: This trial was registered at clinicaltrials.gov as NCT04700904 (https://classic. CLINICALTRIALS: gov/ct2/show/NCT04700904).

Introduction: Parenting styles (PSs) and food-related parenting practices (FPPs) play a crucial role in shaping adolescent eating behavior. This study aimed to investigate the relationship between the different PSs and FPPs of African-American families and the frequency of consumption of MyPlate food items by adolescents based on recommendations from the Dietary Guidelines for Americans (DGA). Methods: This study used a cross-sectional design. Data collection was conducted using Qualtrics through an online survey of 211 African-American parents and their adolescents aged 10-17-year-old. Adolescents completed the Youth and Adolescent Food Frequency Questionnaire to assess their dietary behavior, while parents filled out the survey to identify the degree of PSs (i.e., authoritative, authoritarian, setting rules, and neglecting) and FPPs (i.e., monitoring, reasoning, copying, and modeling). Spearman's rank correlation coefficient, Wilcoxon rank-sum test, and stepwise logistic regression were performed to determine the answers to the research questions. Results: For fruit consumption, authoritative parenting significantly reduced the likelihood of adherence to DGA, while authoritarian, monitoring, and reasoning practices increased it. Female adolescents were more likely to meet fruit intake recommendations, with a similar positive impact observed for those whose parents had above high school education. In vegetable intake, authoritarian and monitoring practices positively impact on adherence to DGA, whereas setting rules had a detrimental impact. Being in a married household also increased vegetable intake DGA adherence. For grain consumption, reasoning was a significant positive predictor, while setting rules negatively impacted adherence. Dairy DGA adherence was positively impacted by monitoring and copying practices, but negatively impacted by female gender. Protein intake showed a positive association with reasoning and parental education. Discussion: Our findings confirm the importance of parenting in developing desired eating behaviors among African-American adolescents. The results of this study can be used to develop culture-based nutritional education programs for parents and youth.
ABSTRACT
OBJECTIVE: Awareness of federal dietary guidelines has been associated with better perceived and objective diet quality. Little is known about the awareness of federal dietary recommendations among persons with chronic kidney disease (CKD) and the associations between recognition of guidelines, perception of diet quality, and objective quality of the diet in this population. DESIGN AND METHODS: We compared awareness of, and engagement with, MyPlate (a representation of 5 food groups from the US Department of Agriculture) along with perceived and objective diet quality, the latter assessed via Dietary Approaches to Stop Hypertension index scores, among US adults with and without CKD during 2017-2020. RESULTS: Among noninstitutionalized adults in the United States, 8.3% had albuminuria with normal or near-normal kidney function, 4.0% had estimated glomerular filtration rate 45-59 mL/minute/1.73 m2 (CKD stage G3a) and 1.6% had estimated glomerular filtration rate <45 mL/minute/1.73 m2 (CKD stages G3b/G4/G5). MyPlate awareness was lower among persons with CKD compared with those without CKD (19.6% vs. 26.4%, P < .001) and was lower among persons with more advanced CKD stages: 20.8%, 18.2%, and 16.3% in persons with CKD stages G1/G2, G3a, and G3b/G4/G5, respectively (trend P < .001). Among persons aware of MyPlate, a numerically higher proportion with CKD attempted to follow MyPlate recommendations (43.9% vs. 32.3%, P = .10); the proportion was highest among persons with moderate-to-advanced CKD (41.9%, 42.9%, and 56.9% among persons with CKD stages G1/G2, G3a, and G3b/G4/G5, respectively (trend P < .001)). Perceived and objective dietary quality (the latter based on concordance with the Dietary Approaches to Stop Hypertension diet) were slightly higher among persons with CKD relative to those without CKD. CONCLUSIONS: Adults with CKD have lower MyPlate awareness than adults without CKD. Enhancing diet education to persons with CKD could improve diet quality and potentially ameliorate CKD-associated complications.
ABSTRACT
BACKGROUND: MyPlate is a tool designed to educate the general US population on how to eat in alignment with the Dietary Guidelines for Americans; yet, there is a lack of data on who has heard of MyPlate over time. OBJECTIVE: The objective of this analysis was to examine the prevalence of awareness of MyPlate within the US population and if awareness changes differentially over time. DESIGN: This study was a serial, cross-sectional survey. PARTICIPANTS/SETTING: Three survey waves of data (2013-2018) were used from the National Health and Nutrition Examination Survey of adults aged 20 years or older (n = 17,023). MAIN OUTCOME MEASURES: Percentage of the US adult population who had heard of MyPlate was measured and stratified by sex, age, citizenship status, education, household food security status, income, receipt of Supplemental Nutrition Assistance Program (SNAP) benefits, and receipt of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) benefits. STATISTICAL ANALYSES PERFORMED: Global Wald tests were used to assess whether prevalence of awareness of MyPlate differed by sociodemographic characteristics. Tests of homogeneity using likelihood ratio tests of nested logistic regression models were used to assess whether differences in awareness of MyPlate by various sociodemographic characteristics changed over time from 2013 to 2018. RESULTS: Twenty percent (19.5%) (n = 875) of the analytic sample of participants aged 20 years and older had heard of MyPlate in 2013-2014, 24.5% (n = 1,020) in 2015-2016, and 24.6% (n = 1,086) in 2017-2018. Awareness of MyPlate changed differentially over time (P value < .1) from 2013 to 2018 by income, household food security status, and receipt of SNAP benefits, with slower increases in awareness for households with lowest income over time, narrowing of differences in awareness by household food security status over time, and persistent differences in awareness by receipt of SNAP benefits over time. CONCLUSIONS: These results highlight the current low awareness of MyPlate, disparities in awareness of MyPlate immediately after implementation by sociodemographic characteristics, and increases in awareness over time at differential rates within levels of income, food security status, and ever receipt of SNAP benefits. Given that the Dietary Guidelines for Americans 2025-2030 are currently in development, new strategies should be considered to disseminate tools that translate the updated Dietary Guidelines in such a way that reach the general population equitably upon implementation within the United States.
ABSTRACT
Concern for the environment when making dietary choices has grown as the contribution of the food sector to global greenhouse gas emissions becomes more widely known. Understanding the correlates of beef eating could assist in the targeting of campaigns to reduce the consumption of high-impact foods. The objective of this study was to identify the demographic, socioeconomic, and behavioral correlates of disproportionate beef consumption in the United States. We analyzed 24-h dietary recall data from adults (n = 10,248) in the 2015-2018 National Health and Nutrition Examination Survey (NHANES). Disproportionate beef consumption was defined as an intake greater than four ounce-equivalents per 2200 kcal. Associations of this indicator variable with gender, age, race/ethnicity, education, family income, diet knowledge, and away-from-home meals were assessed using logistic regression, incorporating survey design and weighting. Disproportionate beef diets were consumed by 12% of individuals, but accounted for half of all beef consumed. Males were more likely than females (p < 0.001) to consume these diets. This relationship was seen in all bivariate and multivariable models. Older adults, college graduates, and those who looked up the MyPlate educational campaign online were less likely (p < 0.01) to consume a disproportionate beef diet. While almost one-third of reported consumption came from cuts of beef (e.g., steak or brisket), six of the top ten beef sources were mixed dishes: burgers, meat mixed dishes, burritos and tacos, frankfurters, soups, and pasta. Efforts to address climate change through diet modification could benefit from targeting campaigns to the highest consumers of beef, as their consumption accounts for half of all beef consumed.

The four-tiered NOVA food classification defines foods based on their degree of processing and ranges from native unprocessed foods to so-called "ultra-processed" foods. Recent publications have suggested that foods classified as ultra-processed are unhealthy and contribute to the obesity epidemic. It is important to distinguish between formulation and processing of a food. In most cases it is the formulation more than the processing that results in foods that are not recommended as part of a healthy diet. Such "ultra-formulated" foods are unhealthy because they are high in added sugar and other caloric sweeteners, refined flours saturated fats and salt to increase palatability. The understanding that processing and formulation are distinct will assist health professionals in identifying the types of foods that are unhealthy and contribute to overconsumption and obesity. It furthermore will help to destigmatize food technology and promote discussions amongst health professionals, food scientists, corporate scientists, government officials and the general public. Novel food processing techniques are urgently needed in times of population growth, climate change and war-induced food shortages.
ABSTRACT
MyPlate is a 2017 campaign about Indonesian Balanced Nutrition Guidelines. Nutrition knowledge of young people plays an important role since nutritional status of young people affects offspring's health. Moreover, they are more likely to be obese later in life, particularly in urban areas. The main objective of this descriptive study was to assess the relationship between knowledge, attitude and practice (KAP) of MyPlate with sociodemographic, body satisfaction (BS), accessibility and source of information. Data were collected in a cross-sectional study involving 413 young people in Jakarta. The online questionnaire was modified from previous studies, validated by three experts, pre-tested and proven to be reliable through Cronbach's alpha value of 0.714. In this study, most participants had poor knowledge (54%), good attitude (80%), fair practice (72%), fair BS (51%) and good accessibility (70%). Chi-square analysis showed significant relationships (p-value < 0.05) of knowledge with BS, education level, major; attitude with accessibility; practice with BS and accessibility; BS with gender; accessibility with socioeconomic status; source of information with education level and major. Moreover, the biggest source of MyPlate information was this questionnaire (45%), which means they were not familiar with MyPlate before. This study verifies the necessity to intensify its promotion and improve nutritional knowledge and practice in young people.

BACKGROUND: Evidence suggests dietary acculturation can increase obesity and chronic disease risks. However, acculturation effects on diet quality among subgroups of Hispanic Americans is not well studied. OBJECTIVES: Estimating percentages of Hispanic Americans with low, moderate, and high acculturation using 2 proxy measures with different language variables was the first objective. Identifying similarities and dissimilarities in diet quality differences by acculturation level between Mexican Americans and other Hispanic Americans was the second objective. METHODS: The study sample included 1733 Mexican American and 1191 other Hispanic participants aged ≥16 y from National Health and Nutrition Examination Survey 2015-2018. Proxy measures included in the 2 acculturation scales were nativity/United States residence length, immigration age, language spoken at home (home), and language of dietary recall (recall). Replicate 24-h dietary recalls were conducted, and diet quality was assessed using the 2015 Healthy Eating Index. Analyses included statistical methods for complex survey designs. RESULTS: For Mexican Americans, 8%, 35%, and 58% had low, moderate, and high acculturation on the home scale compared with 8%, 30%, and 62% on the recall scale. For other Hispanics, 17%, 39%, and 43% had low, moderate, and high acculturation on the home scale compared with 18%, 34%, and 48% on the recall scale. Similarities between ethnicities included higher acculturation associated with lower intakes of fruits, vegetables, total protein foods, seafood and plant proteins, and saturated fats and greater intake of sodium. Dissimilarities included higher acculturation associated with more whole grains and added sugars intakes and less refined grains intake (Mexican Americans), and less total dairy and fatty acids intakes (other Hispanic Americans). CONCLUSIONS: Higher acculturation is associated with worsening diet quality for fruits, vegetables, and protein foods in all Hispanic Americans. However, associations of higher acculturation with worsening diet quality for grains, added sugars, dairy, and fatty acids were present only in specific subgroups of Hispanic Americans.

The quality and quantity of food consumption have changed due to the COVID-19 pandemic. In this study, we examined how the COVID-19 pandemic has changed the consumption of different food groups in order to close the research gap by providing current evidence that reflects a later stage of the pandemic compared to other circulating research conducted at earlier stages. Data collection for this cross-sectional study was performed via an online Qualtrics survey from 10,050 adults aged 40-100 years. Nutritional status was measured using the 24-item short-form Dietary Screening Tool (DST) twice: before and since the COVID-19 pandemic. The DST questions were categorized based on MyPlate items, along with fat, sugar, and sweet items, as well as nutritional supplement intake. In addition, the total DST score was calculated for each participant, which categorized them into one of three groups: "at risk", "possible risk", and "not at risk". The results revealed that the consumption of grains, fruit, lean protein, and dairy decreased significantly, while the consumption of fat, sugar, and sweet items increased significantly due to COVID-19. The biggest decreases in consumption of food subcategories were related to whole grain bread and cereal, followed by fruit as a snack, in comparison with other types of grain and fruit. No changes in the consumption of vegetables, processed meat, or supplement intake were seen. The total DST score showed that, before and since COVID-19, the overall nutrition status of adult Americans has been at risk. In addition, of those participants who were not at risk before COVID-19, 28.5% were either at risk or at possible risk since COVID-19; moreover, of those participants who were at possible risk before COVID-19, 21% were at risk since COVID-19. As a good nutritional status can reduce the risk of severe illness or even mortality rate in times of crisis, the findings of this study can help policymakers and health educators to develop heath-protecting behavior sessions against future pandemics to manage crises.

BACKGROUND: Evidence suggests that acculturation can increase risks of poor diet, obesity, and chronic diseases. Yet questions remain regarding acculturation proxy measures and associations with diet quality in Asian Americans. OBJECTIVES: Primary objectives included estimating percentages of Asian Americans with low, moderate, and high acculturation using 2 proxy measures of acculturation based on different language variables and determining if diet quality differences existed among acculturation levels using the 2 proxy acculturation measures. METHODS: Study sample included 1275 Asian participants aged ≥16 y from National Health and Nutrition Examination Survey 2015-2018. Nativity/length of United States residence, immigration age, language spoken at home (home), and language of dietary recall (recall) were used as proxy measures for 2 acculturation scales. Replicate 24-h dietary recalls were conducted and diet quality was assessed using 2015 Healthy Eating Index. Statistical methods for complex survey designs were used for analysis. RESULTS: Using home and recall language, 26% compared with 9% of participants were classified with low, 50% compared with 63% with moderate, and 24% compared with 28% with high acculturation. On the home language scale, participants with low and/or moderate acculturation had higher scores (0.5-5.5 points) for vegetables, fruits, whole grains, seafood and plant protein, saturated fats, added sugars, and total 2015 Healthy Eating Index than participants with high acculturation; participants with low acculturation had lower refined grain score (1.2 points) than participants with high acculturation. Results were similar for the recall language scale, except differences between participants with moderate and high acculturation were also observed for fatty acids. CONCLUSIONS: Although percentages of Asian Americans classified with low, moderate, and high acculturation differed between the 2 proxy measures for acculturation, diet quality differences among acculturation groups were remarkably similar between the 2 proxy measures. Hence, use of either language variables may yield comparable results regarding the relationships between acculturation and diet in Asian Americans.

BACKGROUND: The Latinx population experiences some of the highest rates of chronic disease, including obesity and type II diabetes. Such conditions may be especially burdensome in rural Latinx communities that often face barriers to accessing disease prevention resources and public health programs. METHODS: Diverse stakeholders (i.e., patients, community members, system of healthcare clinics, community food bank) tailored an existing cookbook, based on the U.S. Department of Agriculture MyPlate healthy eating and dietary guidelines, for local ingredients, health literacy, and language for rural Latinx and Indigenous Latin Americans. The cookbook recipes were disseminated widely via virtual cooking demonstrations, food distribution events, and social media. Pre- and posttest surveys were used to assess changes in diabetes knowledge measured by the 24-item American Diabetes Association Diabetic Knowledge Questionnaire and confidence in dietary behavior change over time measured by 4 questions of the 17-item Mediterranean Diet Index. A mixed effects, repeated measures analysis was conducted with gender ID, age range and educational attainment included as covariates and assessment interval as the predictor (pretest vs posttest) and change in confidence about adhering to four specific components of the Mediterranean diet. Focus groups elicited information on participants' motivation and ability to use the recipes and eat healthy foods following the virtual cooking demonstration participation. RESULTS: A total of 20 virtual cooking demonstrations were conducted and 60 participants completed a pretest survey and 54 a posttest survey, a subsample (n = 19) participated in one of three focus groups. Most participants were female, identified as Latinx/Hispanic, were between the ages of 40-49, and spoke Spanish. 17% identified as Indigenous Latin American specifically as Purépecha, an indigenous group from Michoacán, Mexico. Survey and focus group findings indicated at posttest an increase in diabetes knowledge among participants with no prior diagnosis of chronic health conditions and more confidence in limiting sugary beverages and refined wheat pasta/white rice among indigenous participants. Focus group discussions explicated the quantitative findings. CONCLUSION: This study brought together patients and key stakeholders committed to addressing the social determinants of health and it mobilized the community to develop culturally vetted health education materials. The findings indicate the need for increased access to evidence-based nutrition education and to culturally appropriate food products that can be easily incorporated into daily food preparation.

PURPOSE: To estimate the percentage of United States adults who accurately assessed their diet quality (DQ). DESIGN: Observational, cross-sectional, nationally representative. SETTING: National Health and Nutrition Examination Survey, 2015-2018. SAMPLE: 9757 (86%) of 11 288 adults aged ≥20 years. MEASURES: Perceived DQ was assessed by asking participants, how healthy is your diet? The five responses included excellent, very good, good, fair, and poor. Measured DQ was assessed using 24-hours dietary recalls scored with 2015 Healthy Eating Index; scores were categorized using a 10-point grading scale. ANALYSIS: Matches between perceived and measured DQ that were classified as accurate included: excellent = A, very good = A or B, good = B or C, fair = C or D, and poor = D or F. All others were classified as inaccurate. Analyses included descriptive statistics and multivariable logistic regression for complex survey designs. RESULTS: 63% of adults perceived their DQ as very good or good while 70% scored DQ grades of F. Overall, 15% of adults accurately assessed their DQ with 96% accuracy in the poor perception group and <23% in the other 4 groups. Overall, 75% of adults overrated their DQ. Females, adults with lower educational attainment, and those with low food security were more likely to accurately assess their DQ. CONCLUSION: Adults cannot accurately assess their DQ except for those perceiving their DQ as poor, and the majority overrate their DQ.

OBJECTIVE: To examine teachers' familiarity and use of MyPlate, including barriers to using it. METHODS: Twenty kindergarten through grade 12 teachers were recruited from 1 urban and suburban school district in the Midwest to participate in virtual focus groups regarding familiarity, use, and barriers to MyPlate. A basic descriptive qualitative approach with thematic analysis was guided by systems thinking. Common categories were coded and agreed on by the authors. RESULTS: Findings included main categories of individual awareness, use in curriculum, and appropriate facilitators of MyPlate. Awareness and use of MyPlate were mixed. Teachers integrated MyPlate in math, history, and other subjects. Barriers included packed curriculum and cultural issues. The facilitators of MyPlate mentioned were health or physical education teachers. CONCLUSIONS AND IMPLICATIONS: Online focus groups successfully collected formative data on teachers' perspectives toward MyPlate. The technology could be used in future similar research. Enhanced teacher training may improve the integration of MyPlate into schools. School teachers identified major barriers to MyPlate in the classroom, including lack of time and resources. There was mixed feedback on how MyPlate and nutrition may be used in school curricula. Enhanced teacher training may improve the integration of MyPlate into schools.

Introduction The objective of this article is to analyze whether visual plate-related dietary guidance systems - such as the MyPlate guideline or the Half-Plate Rule - help people eat better when dining at home or in restaurants. Methods To help explore this, 104 young adults were randomly assigned to follow either (1) USDA MyPlate guidelines, (2) the Half-Plate Rule, or (3) no guidelines (control condition). They then used their assigned guidelines to complete the survey while eating a dinner of their choice. They completed a food diary for the meal and then completed a survey about their experience. Results Both the two visual dietary guidance systems (My Plate and the Half-Plate Rule) were considered easy to understand and easy to follow, and they left people with fewer questions about what to eat (all p < 0.01). Understandability is important because those people who rated a system "easy to follow" indicated they had consumed less meat than usual (r = 0.268), but understandability was uncorrelated with fruit and vegetable intake (r = 0.092) and carbohydrate intake (r = 0.069). Conclusions There are three key conclusions to these and other findings: first, the simplest guidance system may be more effective than none. Second, even the most perfect dietary guidance system will not change behavior if (a) the foods are not available, or (b) it is not followed. Third, guidance systems could over-increase the consumption of some foods (such as dairy) they specifically mention, presumably because it makes them more salient in one's mind.
ABSTRACT
Objective: To examine the effect of receiving daily motivational text messages on the change in college students' nutritional choices and levels of physical activity. Participants: Two hundred and one university students participated in an eight-week experimental/control group study. Methods: All participants received a brochure that contained nutritional and physical-activity information. The survey consisted of three parts: demographic information, health and diet, and physical activity. All participants completed a self-administered survey at the beginning and the end of the eight-week study. The experimental group participants received a daily motivational-text message. Results: There were significant interactions between group and time on most of the health and diet items, but there were no significant interactions on the physical activity items. Conclusions: It is crucial to monitor and promote college students' nutrition and physical activity behaviors. The study findings will be vital in designing interventions that enhance college students' general health.

OBJECTIVE: To examine the variety of fruits and vegetables lower income households in the USA can buy while meeting Federal dietary recommendations at different levels of expenditure. DESIGN: Simulation techniques were used to create 3000 market baskets of fruits and vegetables. All baskets contained enough food for a four-person household to meet dietary recommendations for fruits and vegetables over 1 week. Each basket's retail value was estimated along with the ability of a representative household to afford each basket with different levels of expenditure. SETTING: We used data from the US Department of Agriculture's (USDA) Fruit and Vegetable Prices data product which reports a US household's costs to buy each of 157 different fruit and vegetable products per edible cup equivalent. PARTICIPANTS: We consider the situation facing a lower income household that receives maximum benefits through the Supplemental Nutrition Assistance Program (SNAP). These benefits are enough for the household to obtain a nutritious and palatable diet without spending any of its own money on food if it approximately follows USDA's Thrifty Food Plan. RESULTS: Households receiving maximum SNAP benefits can buy a sufficient variety and quantity of fruits and vegetables if they allocate about 40 % of those benefits to these two food groups. However, if households spend less than that amount, the variety of products they can buy while still satisfying recommendations drops off quickly. CONCLUSION: Households that move fruits and vegetables to the centre of their budgets can better afford to meet Federal dietary guidelines.

OBJECTIVE: To understand how adolescents define related nutrition terms and use food groups to classify commonly consumed foods into the MyPlate food groups. DESIGN: Qualitative study with telephone interviews. SETTING: Houston metropolitan area in Texas. PARTICIPANTS: A convenience sample of 21 adolescents from a volunteer database of the research center. MAIN OUTCOMES MEASURES: Sociodemographic questions were asked before semiquantitative structured interviews. The interview focused on understanding how adolescents defined health, other nutrition terms, and food groups, and how to use the MyPlate icon in categorizing commonly consumed foods into groups. ANALYSIS: Hybrid thematic approach with inductive and deductive analyses. RESULTS: Adolescents defined being healthy in terms of wellness-type behaviors (eg, diet, physical activity, and sleep). They perceived clear differences between terms such as healthy vs unhealthy food but struggled to define others (eg, energy-dense foods and processed foods). Mixed dishes, hard candies, chocolate chip cookies, and potato chips were the most difficult foods for the adolescents to classify into the MyPlate food groups, whereas apple, lettuce, and milk were easily classified. CONCLUSIONS AND IMPLICATIONS: Food guidance systems, public health policies, and behavioral nutrition programs targeting adolescents might use health and nutrition terms and prescriptive food categories more clearly understood by adolescents.
