RESUMO
Commercial environments and food acquisition methods significantly shape dietary practices and impact health. This study assesses dietary choices among Portuguese university students regarding vending machines, canteens, and lunches from home. It also evaluates their use of the university canteen and their tendency to bring lunch from home. This pilot cross-sectional study used a self-administered electronic questionnaire, made available in early 2023. Participants were recruited through snowball sampling. The study included 137 students from Portuguese higher education institutions, mainly women (74.5%), pursuing degrees or integrated Master's degrees (83.2%), primarily in health-related fields (55.5%). The median age was 21 years (20 to 23.5 years). About 70.0% regularly consumed food from vending machines, while approximately 60.0% brought lunch from home, avoiding the canteen. Factors such as convenience (48.5%), price (47.5%), product availability (40.6%), and taste (39.6%) mainly influenced vending machine choices. Monthly, chocolates, water, coffee, cookies, treats, and soft drinks were the most commonly acquired items, with coffee being the most frequent daily purchase. These findings provide insights for creating policies and initiatives to promote healthier and more accessible food options for students and strategies to encourage positive eating behaviors.

Importance: Point-of-sale food messaging can encourage healthier purchases, but no studies have directly compared multiple interventions in the field. Objective: To examine which of 4 food and beverage messages would increase healthier vending machine purchases. Design, Setting, and Participants: This randomized trial assessed 13 months (February 1, 2019, to February 29, 2020) of vending sales data from 267 machines and 1065 customer purchase assessments from vending machines on government property in Philadelphia, Pennsylvania. Data analysis was performed from March 5, 2020, to November 8, 2022. Interventions: Study interventions were 4 food and beverage messaging systems: (1) beverage tax posters encouraging healthy choices because of the Philadelphia tax on sweetened drinks; (2) green labels for healthy products; (3) traffic light labels: green (healthy), yellow (moderately healthy), or red (unhealthy); or (4) physical activity equivalent labels (minutes of activity to metabolize product calories). Main Outcomes and Measures: Sales data were analyzed separately for beverages and snacks. The main outcomes analyzed at the transaction level were calories sold and the health status (using traffic light criteria) of each item sold. Additional outcomes were analyzed at the monthly machine level: total units sold, calories sold, and units of each health status sold. The customer purchase assessment outcome was calories purchased per vending trip. Results: Monthly sales data came from 150 beverage and 117 snack vending machines, whereas 1065 customers (558 [52%] male) contributed purchase assessment data. Traffic light labels led to a 30% decrease in the mean monthly number of unhealthy beverages sold (mean ratio [MR], 0.70; 95% CI, 0.55-0.88) compared with beverage tax posters. Physical activity labels led to a 34% (MR, 0.66; 95% CI, 0.51-0.87) reduction in the number of unhealthy beverages sold at the machine level and 35% (MR, 0.65; 95% CI, 0.50-0.86) reduction in mean calories sold. Traffic light labels also led to a 30-calorie reduction (b = -30.46; 95% CI, -49.36 to -11.56) per customer trip in the customer purchase analyses compared to physical activity labels. There were very few significant differences for snack machines. Conclusions and Relevance: In this 13-month randomized trial of 267 vending machines, the traffic light and physical activity labels encouraged healthier beverage purchases, but no change in snack sales, compared with a beverage tax poster. Corporations and governments should consider such labeling approaches to promote healthier beverage choices. Trial Registration: ClinicalTrials.gov Identifier: NCT06260176.

BACKGROUND: The World Health Organization recognizes universities as an important health-promotion setting, including in healthy food provision. Previous research shows that healthy food retail interventions also need to consider commercial sustainability, including financial outcomes, and should take a holistic approach to consumer experience. OBJECTIVE: Our aim was to determine the health behavior and commercial outcomes of a multicomponent traffic light-based healthy vending policy implemented as one part of a holistic university food policy. The hypothesis was that purchases of less healthy "red" beverages would decrease compared with predicted sales, that purchases of healthier "green" and "amber" alternatives would increase, and that there would be no change in revenue. DESIGN: A quasi-experimental design evaluated a real-world food policy using monthly aggregated sales data to compare pre-intervention (January 2016 to March 2018) and post-intervention period sales (December 2018 to December 2019). PARTICIPANTS/SETTING: Electronic sales data were collected from 51 beverage vending machines across 4 university campuses in Victoria, Australia. INTERVENTION: A multicomponent policy was implemented between April and November 2018. Beverages were classified using a voluntary state government traffic light framework. Policy included display ≤20% red beverages and ≥50% green beverages; machine traffic light labeling; health-promoting machine branding; review of machine placement; and recycled bottle packaging. MAIN OUTCOME MEASURES: Changes in red, amber, and green volume sales, and revenue compared with predicated sales. STATISTICAL ANALYSES PERFORMED: Interrupted time series analysis of sales data compared post-policy sales with predicted sales. RESULTS: In the 13th month post-policy implementation, there was a 93.2% (95% CI +35.9% to +150.5%) increase in total beverage volume sold and an 88.6% (95% CI +39.2% to +138.1%) increase in revenue. There was no change in red beverage volume sold, but increases in green (+120.8%; 95% CI +59.0% to +182.6%) and amber (+223.2%; 95% CI +122.4% to +323.9%) volume sold. CONCLUSIONS: Sustained behavior change and commercial outcomes suggest that holistic vending interventions can effectively promote healthier beverage sales.

Vending machines contribute to growing levels of obesity. They typically contain energy dense, high fat snacks and attempts at persuading consumers to switch to healthier snacks sold within the same machine have had limited success. This study explored the health benefits and cost effectiveness of the complete replacement of regular snacks with healthy items. Two vending machines were manipulated in a 6-month trial, with a healthy and regular range of products alternated between the two machines every fortnight. Healthy vending resulted in a 61% drop in calories sold relative to regular vending, significant with time and product range as random factors. There was no evidence of compensatory behaviour from nearby shop sales nor in multi-item purchases from vending machines. The impact on profit was less clear. Sales dropped by 30% during healthy vending but variability across product range meant that the change was not significant. Overall our results demonstrate that complete healthy vending can be introduced in hospitals without a catastrophic loss in sales nor compensatory behaviours that offset the public health gains of consuming healthier products.

INTRODUCTION: Vending machines promote easy access to food with low nutritional value. 'Healthy' vending machines (HVM) have been introduced as a means to improve the availability and accessibility of healthy food options, and the healthiness of the foods, however, has not been evaluated. OBJECTIVE: Our aim was to assess the healthiness of the products offered in HVM and 'conventional' vending machines (CVM), located in the Catalan Institute of Oncology. STUDY DESIGN AND METHODS: All products available in vending machines (HVM (n = 33) and CVM (n = 62) were evaluate during three nutrient profile models (NPMs): the World Health Organization's European Regional Office model (WHO), Nutrient Profile Model UK (NPM-UK), and Australian Health Star Rating system (HSR). RESULTS: Regardless of the NPM used, significant differences found in the proportion of healthy products among HVM and CVM (WHO: P-value = 0.005, NPM-UK: P value < 0.001, HSR: P-value < 0.001). The healthy products offered in HVM accounted for 30%, 73%, and 52% of the total content, while CVM offered 6%, 32%, and 15% of the content, as assessed by WHO, NPM-UK, and HSR, respectively. The WHO model was the most restrictive model, and the NPM-UK was the most permissible one. CONCLUSIONS: Although not all products in HVM are rated as healthy by the different NPMs, the percentage of healthy products was significantly higher than those in CVM.

OBJECTIVE: We evaluated the impact of a community-based healthy beverage procurement and serving practices program, and educational media campaign, on residents' behaviors and beliefs regarding sugary beverages. DESIGN: Repeated cross-sectional population surveys in 2013 and 2014 were conducted, as well as semistructured interviews with key informants. We employed multivariate differences-in-differences regression analysis, adjusting for demographics and weight status, using the survey data. Key informant interviews were reviewed for common themes. SETTING: Three rural counties in upstate New York with high prevalence of children living in poverty and childhood obesity. PARTICIPANTS: Residents of Broome, Cattaraugus, and Chautauqua, with Chemung as a control, reached through cross-sectional random-digit-dial landline and cellular telephones, and practitioners involved in intervention implementation. INTERVENTION: Community organizations were encouraged through presentations to leadership to adopt healthier vending policies, providing more low- and no-sugar options, and were provided assistance with implementation. In addition, a media campaign supported by presentations to the public aimed to educate residents regarding the health consequences of sugary beverage consumption. OUTCOME MEASURES: The survey measured population demographics and sugary beverage consumption frequency, availability, beliefs about harmfulness, and support for regulation, pre- and postintervention. Key informant interviews elicited perceived program challenges and successes. RESULTS: Compared with temporal trends in the control county, availability of regular soda in the intervention counties decreased (differences-in-differences estimator: ß = -.341, P = .04) and support for regulation increased (differences-in-differences estimator: ß = .162, P = .02). However, there were no differences regarding beliefs about harmfulness or consumption. Practitioners confirmed that the intervention increased awareness but was insufficient to spur action. CONCLUSION: Although public education on the harmfulness of sugary beverages and provision of healthier options in some vending machines successfully impacted soda availability and support for regulation, it did not reduce consumption. This intervention seems promising but should be paired with other community-based interventions for a more comprehensive approach.

BACKGROUND: Altering the availability of healthier or less-healthy products may increase healthier purchases, but evidence is currently limited. The current study aimed to investigate the impact of altering the absolute-and-relative availability of healthier and less-healthy products - i.e. simultaneously altering the number of options available and the proportion of healthier options - in hospital vending machines. METHODS: An adapted multiple treatment reversal design was used, altering products available in ten vending machines serving snack foods and/or cold drinks in one English hospital. Machines were randomised to one of two sequences for the seven 4-week study periods: ABCADEA or ADEABCA. In Condition A (study periods 1, 4 and 7) the proportions of healthier products were standardised across all machines, so that 25% of all snack slots and 75% of drink slots were healthier. In Condition B, 20% of vending machine slots were emptied by removing less-healthy products. In Condition C, the empty slots created in Condition B were filled with healthier products. Conditions D and E were operationalised in the same way as B and C, except healthier products were removed in D, and then less-healthy products added in E. Sales data were obtained from machine restocking records. Separate linear mixed models were conducted to examine the impact of altering availability on energy purchased (kcal) from (i) snacks or (ii) drinks each week, with random effects for vending machine. RESULTS: The energy purchased from drinks was reduced when the number of slots containing less-healthy drinks was decreased, compared to standardised levels (- 52.6%; 95%CI: - 69.3,-26.9). Findings were inconclusive for energy purchased from snacks when less-healthy snack slots were reduced (- 17.2%; 95%CI: - 47.4,30.5). Results for altering the number of slots for healthier drinks or snacks were similarly inconclusive, with no statistically significant impact on energy purchased. CONCLUSIONS: Reducing the availability of less-healthy drinks could reduce the energy purchased from drinks in vending machines. Further studies are needed to establish whether any effects might be smaller for snacks, or found with higher baseline proportions of healthier options.

INTRODUCTION: Each year, millions of people purchase food at highway rest areas. Rest areas are potential sites for health promotion because they are operated by the public sector; they are frequently visited by professional truck drivers, who have a disproportionate burden of chronic disease; and they are easily accessible. To our knowledge, no research has systematically examined the healthfulness of food offerings at rest areas. The objective of this study was to determine the accessibility and healthfulness of food and beverages offered at highway rest areas in North Carolina using a mixed-methods audit and geospatial approach. METHODS: We conducted a cross-sectional audit of all rest areas offering foods and beverages in North Carolina (N = 30) in summer 2018. We used the Nutrition Environment Measures Survey-Vending (NEMS-V) to record the 1) type, price, and size of all foods and beverages and 2) healthfulness of items offered (based on NEMS-V categorization). Two researchers independently double coded NEMS-V data. We used geospatial analysis to examine proximity of rest areas to food stores. We analyzed data by using univariate and bivariate analysis. RESULTS: The mean number of vending machines per site was 8.0 (range, 2-12, standard deviation, 2.8). The healthfulness of offerings varied across sites. Most food items (88.1%; 2,922 of 3,315) and beverage items (63.7%; 1,567 of 2,459) were classified as least healthful. Cold beverage machines had a greater percentage of healthful items (38.2%; 778 of 2,036) than snack machines (11.4%; 374 of 3,270) (P < .001), mainly because of water and diet soda in beverage machines. CONCLUSION: Policy changes are needed to increase the number and presentation of healthful food options at highway rest areas. Policy changes could provide travelers with more healthful options conveniently located along their travel route.

PURPOSE: As part of wellness efforts, employers may seek to improve the nutritional quality of foods offered and consumed in cafeterias and vending machines. However, little is known about who consumes food from these venues and the types and dietary quality of the foods consumed. DESIGN: Cross-sectional. SETTING: Nonschool cafeterias and vending machines. PARTICIPANTS: US adults ≥20 years old. MEASURES: Prevalence of consuming foods, most common foods eaten, leading calorie sources, 2010 Healthy Eating Index. ANALYSIS: Using 24-hour dietary recall data from NHANES 2005-2014 (N = 25,549 adults), we estimated the prevalence of consuming foods, assessed the most commonly consumed foods, and calculated dietary quality of foods. RESULTS: On a given day, 3.1% of adults consumed foods from cafeterias and 3.9% from vending machines. Consumers averaged 692 kcal from cafeterias and 264 kcal from vending machines. Cafeteria consumers had higher income and education, while vending consumers were more likely to be male and younger adults. Common cafeteria foods included vegetables and fruits, but cafeteria foods were generally high in sodium and low in whole grains. Sugar-sweetened beverages and candies accounted for approximately half of all vending calories. CONCLUSION: Foods chosen from cafeterias and vending machines do not align well with the Dietary Guidelines for Americans. Improving the dietary quality of foods consumed from these venues could impact millions of adults.

OBJECTIVE: Framing of fiscal incentives has been suggested to be important in influencing purchase decisions. We aimed to examine the effect of framing a modest price difference between high- and lower-sugar beverages as a tax or a subsidy respectively, using messages placed on vending machines to influence beverage purchases. DESIGN/SETTING: This is an 11-week randomized crossover trial conducted between August and November 2015, with a two-week run-in period before intervention, targeted at students, staff and faculty of a university campus in Singapore. Twenty-one beverage vending machines were used to implement the intervention involving 'tax message', 'subsidy message' and 'no message (control)'. The former two messages suggest 'a tax for high sugar beverages' or 'a subsidy for lower sugar beverages' respectively. Prices of the beverages offered were fixed at baseline and remained the same in all three experimental conditions: lower-sugar beverage options were priced ~ 10% lower than the corresponding high-sugar option. The machines were randomized to one of the 6 sequences of intervention. Each message intervention period was 3 weeks. The effect of messages was assessed by comparing average weekly units of beverages sold between interventions using mixed effects model. RESULTS: The average weekly units of high and lower-sugar beverages sold per vending machine were 115 and 98 respectively in the control condition. The percentage of high-sugar beverages sold was 54% in the control, 53% in the tax, and 54% in the subsidy message condition. There was no difference in the weekly units of high-sugar beverages sold for the tax message (- 2, 95% CI -8 to 5, p = 0.61) or the subsidy message (0, 95% CI -10 to 10, p = 0.96) conditions as compared with the control condition. Similarly, there was no difference in the weekly units of lower-sugar beverages sold for the tax message (4, 95% CI -4 to 13, p = 0.32) or the subsidy message (7, 95% CI -4 to 18, p = 0.18) conditions as compared with the control condition. CONCLUSIONS: The use of tax and subsidy messages to highlight modest price differences did not substantially reduce high-sugar beverage sales in vending machines on an Asian university campus.

PURPOSE: To determine whether increasing the proportion of healthier options in vending machines decreases the amount of calories, fat, sugar, and sodium vended, while maintaining total sales revenue. DESIGN: This study evaluated the impact of altering nutritious options to vending machines throughout the Banner Health organization by comparing vended items' sales and nutrition information over 6 months compared to the same 6 months of the previous year. SETTING: Twenty-three locations including corporate and patient-care centers. INTERVENTION: Changing vending machine composition toward more nutritious options. MEASURES: Comparisons of monthly aggregates of sales, units vended, calories, fat, sodium, and sugar vended by site. ANALYSIS: A pre-post analysis using paired t tests comparing 6 months before implementation to the equivalent 6 months postimplementation. RESULTS: Significant average monthly decreases were seen for calories (16.7%, P = .002), fat (27.4%, P ≤ .0001), sodium (25.9%, P ≤ .0001), and sugar (11.8%, P = .045) vended from 2014 to 2015. Changes in revenue and units vended did not change from 2014 to 2015 ( P = .58 and P = .45, respectively). CONCLUSION: Increasing the proportion of healthier options in vending machines from 20% to 80% significantly lowered the amount of calories, sodium, fat, and sugar vended, while not reducing units vended or having a negative financial impact.

CONTEXT: Healthy vending machine policies are viewed as a promising strategy for combating the growing obesity epidemic in the United States. Few studies have evaluated the short- and intermediate-term outcomes of healthy vending policies, especially for interventions that require 100% healthy products to be stocked. OBJECTIVE: To evaluate the potential impact of a 100% healthy vending machine nutrition policy. DESIGN: The vendor's quarterly revenue, product sales records, and nutritional information data from 359 unique vending machines were used to conduct a baseline and follow-up policy analysis. SETTING: County of Los Angeles facilities, 2013-2015. PARTICIPANTS: Vending machines in facilities located across Los Angeles County. INTERVENTION: A healthy vending machine policy executed in 2013 that required 100% of all products sold in contracted machines meet specified nutrition standards. OUTCOME MEASURES: Policy adherence; average number of calories, sugar, and sodium in food products sold; revenue change. RESULTS: Policy adherence increased for snacks and beverages sold by the vending machines by 89% and 98%, respectively. Average snack and beverage revenues decreased by 37% and 34%, respectively, during the sampled period. CONCLUSIONS: Although a 100% healthy vending policy represents a promising strategy for encouraging purchases of healthier foods, steps should be taken to counteract potential revenue changes when planning its implementation.

OBJECTIVE: To assess whether the food and drink retail outlets in two major National Health Service (NHS) district general hospitals in England adhere to quality statements 1-3 of the UK National Institute for Health and Care Excellence (NICE) quality standard 94. DESIGN: Cross-sectional, descriptive study to assess the food and drink options available in vending machines, restaurants, cafes and shops in two secondary care hospitals. MAIN OUTCOME MEASURES: Adherence to quality statement 1 whereby the food and drink items available in the vending machines were classified as either healthy or less healthy using the Nutrient Profiling Model (NPM). Compliance with quality statements 2 and 3 was assessed through the measurement of how clearly the shops, cafes and restaurants displayed nutrition information on menus, and the availability and prominent display of healthy food and drink options in retail outlets, respectively. RESULTS: Adherence to quality statement 1 was poor. Of the 18 vending machines assessed, only 7 (39%) served both a healthy food and a healthy drink option. Neither hospital was compliant with quality statement 2 wherein nutritional information was not available on menus of food providers in either hospital. There was inconsistent compliance with quality standard 3 whereby healthy food and drink options were prominently displayed in the two main hospital restaurants, but all shops and cafes prioritised the display of unhealthy items. CONCLUSIONS: Neither hospital was consistently compliant with quality statements 1-3 of the NICE quality standard 94. Improving the availability of healthy foods and drinks while reducing the display and accessibility to less healthy options in NHS venues may improve family awareness of healthy alternatives. Making it easier for parents to direct their children to healthier choices is an ostensibly central component of our healthcare system.

OBJECTIVES: We investigated the extent to which a sample of Ontario and Alberta secondary schools are being compliant with their respective provincial nutrition policies, in terms of the food and beverages sold in vending machines. METHODS: This observational study used objective data on drinks and snacks from vending machines, collected over three years of the COMPASS study (2012/2013-2014/2015 school years). Drink (e.g., sugar-containing carbonated/non-carbonated soft drinks, sports drinks, etc.) and snack (e.g., chips, crackers, etc.) data were coded by number of units available, price, and location of vending machine(s) in the school. Univariate and bivariate analyses were undertaken using R version 3.2.3. In order to assess policy compliancy over time, nutritional information of products in vending machines was compared to nutrition standards set out in P/PM 150 in Ontario, and those set out in the Alberta Nutrition Guidelines for Children and Youth (2012) in Alberta. RESULTS: Results reveal a decline over time in the proportion of schools selling sugar-containing carbonated soft drinks (9% in 2012/2013 vs. 3% in 2014/2015), crackers (26% vs. 17%) and cake products (12% vs. 5%) in vending machines, and inconsistent changes in the proportion selling chips (53%, 67% and 65% over the three school years). Conversely, results highlight increases in the proportion of vending machines selling chocolate bars (7% vs. 13%) and cookies (21% vs. 40%) between the 2012/2013 and 2014/2015 school years. CONCLUSION: Nutritional standard policies were not adhered to in the majority of schools with respect to vending machines. There is a need for investment in formal monitoring and evaluation of school policies, and the provision of information and tools to support nutrition policy implementation.

OBJECTIVES: As part of an evaluation of Ontario's School Food and Beverage Policy (P/PM 150) in a populous Ontario region, this research aimed to: 1) identify, describe and categorize beverages and snacks available for purchase in secondary school vending machines according to P/PM 150 standards; and 2) compare the number and percentage of beverages and snacks within P/PM 150 categories (Sell Most, Sell Less, Not Permitted) from Time I (2012/2013) to Time II (2014). METHODS: Representatives from consenting secondary schools assisted researchers in completing a Food Environmental Scan checklist in Times I and II. Sourced nutritional content information (calories, fats, sodium, sugars, ingredients and % daily values) was used to categorize products. The number and percentage of products in P/PM 150 categories were compared between Times by paired t-tests. RESULTS: Of 26 secondary schools participating in total, 19 participated in both Time periods and were included in the study. There were 75 beverages identified (59 Time I, 45 Time II), mostly water, juices and milk-based beverages; and 132 types of snacks (87 Time I, 103 Time II), mostly grain-based snacks, vegetable/fruit chips, and baked goods. A majority of schools offered one or more Not Permitted beverages (47% Time I, 58% Time II) or snacks (74% Time I, 53% Time II). Significantly more schools met P/PM 150 standards for snacks (p = 0.02) but not beverages in Time II. CONCLUSION: Full P/PM 150 compliance was achieved by few schools, indicating that schools, school boards, public health, and food services need to continue to collaborate to ensure nutrient-poor products are not sold to students in school settings.

INTRODUCTION: In an analysis of smoking using a longitudinal sample of US young adults, we extend research on tobacco vending machine restrictions beyond its prior focus on minors by examining the influence of total vending machine restrictions, which apply to adult-only facilities and represents the only remaining vending machine exemption since the enactment of the Family Smoking Prevention and Tobacco Control Act. We identify whether the passage of a restriction influences an individual's smoking on repeated observations, and if the propensity is lower among those who live in locations with a restriction. METHODS: Combining a repository of US tobacco policies at all geographic levels with the nationally-representative geocoded National Longitudinal Survey of Youth 1997 and Census data, we use multilevel logistic regression to examine the impact of total vending machine restrictions on any past 30-day smoking and past 30-day smoking of one pack per day among young adults (ages 19-31), while accounting for other tobacco control policy, community, and individual covariates. RESULTS: We find that total vending machine restrictions decrease any recent smoking (OR = 0.451; p < .01), net of other covariates. Though the passage of a restriction does not alter an individual's smoking over time, living longer in an area that has a restriction lowers the propensity that an individual will smoke at all (OR = 0.442; p < .05). We find no effect of total vending machine restrictions on smoking a pack daily. CONCLUSIONS: Total vending machine restrictions appear to be an effective, yet highly underutilized, means of tobacco control. IMPLICATIONS: Past scientific inquiries examining vending machine restrictions have focused upon minor access, adolescent perceptions of availability, and subsequent smoking. The potential for total vending machine restrictions, which extend to adult-only facilities, to influence patterns of smoking among those of legal age, remains significant. Those who are subject to total vending machine restrictions for longer periods are less likely to have recently smoked, but individuals do not change their smoking behavior in response to the passage of a restriction. These restrictions do not affect heavy smokers. Such policies are an effective but underutilized policy mechanism to prevent smoking among young adults.

BACKGROUND: This study examined the availability of foods sold in vending machines and school stores in United States public and private schools, and associations of availability with students' food purchases and consumption. METHODS: Descriptive analyses, chi-square tests, and Spearman product-moment correlations were conducted on data collected from 521 students aged 8 to 15 years recruited from orthodontic offices in California. RESULTS: Vending machines were more common in private schools than in public schools, whereas school stores were common in both private and public schools. The food items most commonly available in both vending machines and school stores in all schools were predominately foods of minimal nutritional value (FMNV). Participant report of availability of food items in vending machines and/or school stores was significantly correlated with (1) participant purchase of each item from those sources, except for energy drinks, milk, fruits, and vegetables; and (2) participants' friends' consumption of items at lunch, for 2 categories of FMNV (candy, cookies, or cake; soda or sports drinks). CONCLUSIONS: Despite the Child Nutrition and Women, Infants, and Children (WIC) Reauthorization Act of 2004, FMNV were still available in schools, and may be contributing to unhealthy dietary choices and ultimately to health risks.

This ecologic study evaluated the association between school policy allowing students to purchase sports drinks from school vending machines and school stores and student body mass index (BMI). Data were from surveillance surveys of Minnesota secondary schools (n = 238) and students (n = 59,617), administered in 2012 and 2013, respectively. We used generalized linear models to assess the association between policies and mean age- and sex-adjusted BMI percentile. In adjusted multivariate analysis, school policy was positively associated with BMI percentile (P = .005). School policy restricting student access to sports drinks at school may contribute to decreasing consumption of sport drinks among school-aged youth and improving student weight outcomes in this population.

The study objective was to examine the nutritional quality of competitive foods and beverages (foods and beverages from vending machines and à la carte foods) available to rural middle school students, before implementation of the US Department of Agriculture's Smart Snacks in School standards in July 2014. In spring 2014, we audited vending machines and à la carte cafeteria foods and beverages in 8 rural Appalachian middle schools in Virginia. Few schools had vending machines. Few à la carte and vending machine foods met Smart Snacks in School standards (36.5%); however, most beverages did (78.2%). The major challenges to meeting standards were fat and sodium content of foods. Most competitive foods (62.2%) did not meet new standards, and rural schools with limited resources will likely require assistance to fully comply.
