Food Service Guideline Policies on Local Government-Controlled Properties.

PURPOSE: Local governments can implement food service guideline (FSG) policies, which, in large cities, may reach millions of people. This study identified FSG policies among the 20 largest US cities and analyzed them for key FSG policy attributes. DESIGN: Quantitative research. SETTING: Local government facilities. PARTICIPANTS: Twenty largest US cities. MEASURES: Frequency of FSG policies and percent alignment to tool. ANALYSIS: Using municipal legal code libraries and other data sources, FSG policies enacted as of December 31, 2016, were identified. Full-text reviews were conducted of identified policies to determine whether they met inclusion criteria. Included policies were analyzed for key policy attributes specific to nutrition, behavioral design, implementation, and facility efficiency. RESULTS: Searches identified 469 potential FSG policies, of which 6 policies across 5 cities met inclusion criteria. Five policies met a majority of criteria assessed by the classification tool. Overall alignment to the tool ranged from 17% to 88%. Of the 6 policies, 5 met a majority of the nutrition attributes and 5 met at least 50% of attributes associated with implementation. No policies met the attributes associated with facility efficiency. CONCLUSION: The FSG policies were identified in 5 of the 20 US cities. Policy alignment was high for nutrition and implementation attributes. This analysis suggests that when cities adopt FSG policies, many develop policies that align with key policy attributes. These policies can serve as models for other jurisdictions to create healthier food access through FSGs.

Foods Consumed by US Adults From Cafeterias and Vending Machines: NHANES 2005 to 2014.

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.

Worksite Food and Physical Activity Environments and Wellness Supports Reported by Employed Adults in the United States, 2013.

PURPOSE: To examine the workplace food and physical activity (PA) environments and wellness culture reported by employed United States adults, overall and by employer size. DESIGN: Cross-sectional study using web-based survey on wellness policies and environmental supports for healthy eating and PA. SETTING: Worksites in the United States. PARTICIPANTS: A total of 2101 adults employed outside the home. MEASURES: Survey items were based on the Centers for Disease Control and Prevention Worksite Health ScoreCard and Checklist of Health Promotion Environments and included the availability and promotion of healthy food items, nutrition education, promotion of breast-feeding, availability of PA amenities and programs, facility discounts, time for PA, stairwell signage, health promotion programs, and health risk assessments. ANALYSIS: Descriptive statistics were used to examine the prevalence of worksite environmental and facility supports by employer size (<100 or ≥100 employees). Chi-square tests were used to examine the differences by employer size. RESULTS: Among employed respondents with workplace food or drink vending machines, approximately 35% indicated the availability of healthy items. Regarding PA, 30.9% of respondents reported that their employer provided opportunities to be physically active and 17.6% reported worksite exercise facilities. Wellness programs were reported by 53.2% working for large employers, compared to 18.1% for smaller employers. CONCLUSION: Employee reports suggested that workplace supports for healthy eating, PA, and wellness were limited and were less common among smaller employers.

Food Service Guideline Policies on State Government-Controlled Properties.

PURPOSE: Food service guideline (FSG) policies can impact millions of daily meals sold or provided to government employees, patrons, and institutionalized persons. This study describes a classification tool to assess FSG policy attributes and uses it to rate FSG policies. DESIGN: Quantitative content analysis. SETTING: State government facilities in the United States. PARTICIPANTS: Participants were from 50 states and District of Columbia in the United States. MEASURES: Frequency of FSG policies and percentage alignment to tool. ANALYSIS: State-level policies were identified using legal research databases to assess bills, statutes, regulations, and executive orders proposed or adopted by December 31, 2014. Full-text reviews were conducted to determine inclusion. Included policies were analyzed to assess attributes related to nutrition, behavioral supports, and implementation guidance. RESULTS: A total of 31 policies met the inclusion criteria; 15 were adopted. Overall alignment ranged from 0% to 86%, and only 10 policies aligned with a majority of the FSG policy attributes. Western states had the most FSG policies proposed or adopted (11 policies). The greatest number of FSG policies were proposed or adopted (8 policies) in 2011, followed by the years 2013 and 2014. CONCLUSION: The FSG policies proposed or adopted through 2014 that intended to improve the food and beverage environment on state government property vary considerably in their content. This analysis offers baseline data on the FSG landscape and information for future FSG policy assessments.

Support for Food and Beverage Worksite Wellness Strategies and Sugar-Sweetened Beverage Intake Among Employed U.S. Adults.

PURPOSE: Sugar-sweetened beverage (SSB) consumption is high among U.S. adults and is associated with obesity. Given that more than 100 million Americans consume food or beverages at work daily, the worksite may be a venue for interventions to reduce SSB consumption. However, the level of support for these interventions is unknown. We examined associations between workday SSB intake and employees' support for worksite wellness strategies (WWSs). DESIGN: We conducted a cross-sectional study using data from Web-based annual surveys that gather information on health-related attitudes and behaviors. SETTING: Study setting was the United States. SUBJECTS: A total of 1924 employed adults (≥18 years) selected using probability-based sampling. MEASURES: The self-reported independent variable was workday SSB intake (0, <1 or ≥1 times per day), and dependent variables were employees' support (yes/no) for the following WWSs: (1) accessible free water, (2) affordable healthy food/drink, (3) available healthy options, and (4) less available SSB. ANALYSIS: Multivariable logistic regression was used to control for sociodemographic variables, employee size, and availability of cafeteria/vending machine. RESULTS: About half of employees supported accessible free water (54%), affordable healthy food/drink (49%), and available healthy options (46%), but only 28% supported less available SSB. Compared with non-SSB consumers, daily SSB consumers were significantly less supportive of accessible free water (adjusted odds ratio, .67; p < .05) or less available SSB (odds ratio, .49; p < .05). CONCLUSION: Almost half of employees supported increasing healthy options within worksites, although daily workday SSB consumers were less supportive of certain strategies. Lack of support could be a potential barrier to the successful implementation of certain worksite interventions.

Nutrition Standards for Food Service Guidelines for Foods Served or Sold in Municipal Government Buildings or Worksites, United States, 2014.

INTRODUCTION: The Institute of Medicine and Centers for Disease Control and Prevention have recommended that government agencies use nutrition standards for foods and beverages sold and provided at their facilities. In this study, we examine written nutrition standards for foods sold or served in local government buildings or worksites among US municipalities. METHODS: We used data from a 2014 national survey of 1,945 municipal governments serving populations of 1,000 or more to assess the presence of written nutrition standards, the food groups or nutrients addressed by standards, and the populations served by facilities where standards are applied. The prevalence of standards was estimated by municipality population size, rural-urban status, census region, poverty prevalence, education level, and racial/ethnic composition. RESULTS: Overall, 3.2% of US municipalities reported nutrition standards with greater prevalence observed among large municipalities (12.8% of municipalities with ≥50,000 people vs 2.2% of municipalities with <2,500 people, P < .001). Prevalence differed by region, and standards were most common in the West (6.6%) and least common in the Midwest (2.0%, P = .003).The most common nutrition topics addressed in standards were offering low-calorie beverages, fruits and vegetables, and free drinking water. Most standards applied to facilities serving government employees (67%) or the general public (66%), with fewer serving institutionalized populations (23%). CONCLUSION: Few municipal governments reported having written nutrition standards for foods and beverages sold in their facilities in 2014. Implementing nutrition standards for foods sold or served by local governments is a strategy for increasing access to healthier foods and beverages among municipal employees and local residents.

Comparison of nutrition standards and other recommended procurement practices for improving institutional food offerings in Los Angeles County, 2010-2012.

National, state, and local institutions that procure, distribute, sell, and/or serve food to employees, students, and the public are increasingly capitalizing on existing operational infrastructures to create healthier food environments. Integration of healthy nutrition standards and other recommended practices [e.g., energy (kilocalories) postings at point-of-purchase, portion size restrictions, product placement guidelines, and signage] into new or renewing food service and vending contracts codifies an institution's commitment to increasing the availability of healthful food options in their food service venues and vending machines. These procurement requirements, in turn, have the potential to positively influence consumers' food-purchasing behaviors. Although these strategies are becoming increasingly popular, much remains unknown about their context, the processes required to implement them effectively, and the factors that facilitate their sustainability, especially in such broad and diverse settings as schools, county government facilities, and cities. To contribute to this gap in information, we reviewed and compared nutrition standards and other best practices implemented recently in a large school district, in a large county government, and across 10 municipalities in Los Angeles County. We report lessons learned from these efforts.

Developing and implementing health and sustainability guidelines for institutional food service.

Health and sustainability guidelines for institutional food service are directed at improving dietary intake and increasing the ecological benefits of the food system. The development and implementation of institutional food service guidelines, such as the Health and Human Services (HHS) and General Services Administration (GSA) Health and Sustainability Guidelines for Federal Concessions and Vending Operations (HHS/GSA Guidelines), have the potential to improve the health and sustainability of the food system. Institutional guidelines assist staff, managers, and vendors in aligning the food environment at food service venues with healthier and more sustainable choices and practices. Guideline specifics and their effective implementation depend on the size, culture, nature, and management structure of an institution and the individuals affected. They may be applied anywhere food is sold, served, or consumed. Changing institutional food service practice requires comprehensive analysis, engagement, and education of all relevant stakeholders including institutional management, members of the food supply chain, and customers. Current examples of food service guidelines presented here are the HHS and GSA Health and Sustainability Guidelines for Federal Concessions and Vending Operations, which translate evidence-based recommendations on health and sustainability into institutional food service practices and are currently being implemented at the federal level. Developing and implementing guidelines has the potential to improve long-term population health outcomes while simultaneously benefitting the food system. Nutritionists, public health practitioners, and researchers should consider working with institutions to develop, implement, and evaluate food service guidelines for health and sustainability.

Farm to institution: creating access to healthy local and regional foods.

Farm to Institution (FTI) programs are one approach to align food service operations with health and sustainability guidelines, such as those recently developed by the U.S. Department of Health and Human Services and General Services Administration. Programs and policies that support sourcing local and regional foods for schools, hospitals, faith-based organizations, and worksites may benefit institutional customers and their families, farmers, the local community, and the economy. Different models of FTI programs exist. On-site farmer's markets at institutions have been promoted on federal government property, healthcare facilities, and private institutions nationwide. Farm to School programs focus on connecting schools with local agricultural production with the goal of improving school meals and increasing intake of fruits and vegetables in children. Sourcing food from local farms presents a number of challenges including cost and availability of local products, food safety, and liability considerations and lack of skilled labor for food preparation. Institutions utilize multiple strategies to address these barriers, and local, state, and federal polices can help facilitate FTI approaches. FTI enables the purchasing power of institutions to contribute to regional and local food systems, thus potentially affecting social, economic, and ecological systems. Local and state food policy councils can assist in bringing stakeholders together to inform this process. Rigorous research and evaluation is needed to determine and document best practices and substantiate links between FTI and multiple outcomes. Nutritionists, public health practitioners, and researchers can help communities work with institutions to develop, implement, and evaluate programs and policies supporting FTI.

Strategies for pediatric practitioners to increase fruit and vegetable consumption in children.

High intake of fruits and vegetables (FV) is associated with a decreased risk for many chronic diseases and may assist in weight management, but few children and adolescents consume the recommended amounts of FV. The pediatric practitioner can positively influence FV consumption of children through patient-level interventions (eg, counseling, connecting families to community resources), community-level interventions (eg, advocacy, community involvement), and health care facility-level interventions (eg, creating a healthy food environment in the clinical setting). This article reviews the importance of FV consumption, recommended intakes for children, and strategies by which pediatric practitioners can influence FV consumption of children.

Fruit and vegetable intake among adolescents and adults in the United States: percentage meeting individualized recommendations.

CONTEXT: Fruit and vegetable intake is an important part of a healthy diet and is associated with numerous positive health outcomes. MyPyramid provides recommendations for fruit and vegetable consumption based on individual calorie requirements as determined by an individual's age, sex, and physical activity level. OBJECTIVES: To determine (1) median fruit and vegetable consumption from all dietary sources among adolescent and adult consumers and the percentage of adolescents and adults meeting individual recommended intake levels based on caloric requirements and (2) consumption levels among various demographic groups, intake levels from subtypes of fruits and vegetables, and primary contributors to fruit and vegetable intake. DESIGN: Analysis of 2-day, 24-hour recall data from the 2003-2004 National Health and Nutrition Examination Survey (NHANES), a continuous, nationally representative, cross-sectional survey. RESULTS: This study included dietary contributions of fruits and vegetables from all dietary sources. Fewer than 1 in 10 Americans meet their calorie-specific MyPyramid fruit or vegetable recommendations. Higher intake was not observed in subgroups with higher recommendations for fruit and vegetable consumption based on caloric requirements. The primary contributors to total fruit intake were whole fruits among adults and fruit juices among adolescents. The largest single contributor to overall fruit intake was orange juice. Potatoes dominated vegetable consumption, particularly among adolescents, in whom fried potatoes increased the median vegetable intake from 0.72 cup to 1.21 cups per day. Dark green and orange vegetables and legumes accounted for a small portion of vegetable intake, and few people met the recommendations. CONCLUSIONS: Few American adolescents or adults reported consuming the recommended amounts of fruits or vegetables. Increasing consumption will probably require multifaceted approaches that augment educational campaigns with policy and environmental strategies aimed at the food system at large, from farm to plate, including schools, worksites, and retail establishments. Increasing America's fruit and vegetable consumption is an important public health strategy for weight management and reduction of risk for chronic disease.

Dietary fructose consumption among US children and adults: the Third National Health and Nutrition Examination Survey.

CONTEXT: High fructose intake has been associated with increased de novo lipogenesis in the liver as well as increased plasma triglycerides, insulin resistance, and obesity. Fructose occurs naturally in fruits and vegetables; however, it is added to many processed foods as table sugar (sucrose) and high-fructose corn syrup. Dietary data from a nationally representative sample in 1977-1978 estimated that mean consumption of fructose was 37 g/day (8% of total intake). Little is known about more recent fructose consumption patterns. OBJECTIVE: We determined the amount and sources of dietary fructose among US adults and children. DESIGN: We examined fructose consumption patterns by sex, age group, race/ethnicity, socioeconomic status, and body mass index for 21,483 children and adults. We used a single 24-hour dietary recall administered in the third National Health and Examination Survey (NHANES). MAIN OUTCOME MEASURE: Weighted estimates of fructose intake were tested for significant differences (P < .05) between groups. RESULTS: The mean consumption of fructose was estimated to be 54.7g/day (range, 38.4-72.8) and accounted for 10.2% of total caloric intake. Consumption was highest among adolescents (12-18 years) at 72.8 g/day (12.1% of total calories). One fourth of adolescents consumed at least 15% of calories from fructose. The largest source of fructose was sugar-sweetened beverages (30%) followed by grains (22%) and fruit or fruit juice (19%). CONCLUSIONS: Over 10% of Americans' daily calories were from fructose. These results, when compared with a previous nationally representative study, suggest that fructose consumption has increased. Further research is needed to understand the impact of increased intake of fructose on human health.

Trends in fruit and vegetable consumption among U.S. men and women, 1994-2005.

INTRODUCTION: Eating a diet high in fruits and vegetables as part of an overall healthful diet can help lower chronic disease risk and aid in weight management. Increasing the percentage of Americans who consume enough fruits and vegetables every day is part of the Healthy People 2010 objectives for the nation. Assessing trends in consumption of these foods is important for tracking public health initiatives to meet this goal and for planning future objectives. METHODS: We assessed total and sex-specific changes in daily consumption of fruits and vegetables among 1,227,969 adults in the 50 U.S. states and the District of Columbia who participated in the Behavioral Risk Factor Surveillance System from 1994 through 2005. To estimate changes in consumption according to dietary recommendations that were in place during the years examined, we used geometric mean and the percentage of people eating fruits or vegetables or both five or more times per day. Estimates were standardized for sex, age, and race/ethnicity and analyzed by multivariate regression. RESULTS: From 1994 through 2005, the geometric mean frequency of consumption of fruits and vegetables declined slightly (standardized change: men and women, -0.22 times/day; men, -0.26 times/day; women, -0.17 times/day). The proportion of men and women eating fruits or vegetables or both five or more times per day was virtually unchanged (men, 20.6% vs 20.3%; women, 28.4% vs 29.6%); however, we found small increases for men aged 18 to 24 years and for women who were aged 25 to 34 years, non-Hispanic black, or nonsmokers. Consumption of fruit juice and non-fried potatoes declined for both sexes. CONCLUSION: The frequency of fruit and vegetable consumption changed little from 1994 through 2005. If consumption is to be increased, we must identify and disseminate promising individual and environmental strategies, including policy change.

Multivitamin use in relation to self-reported body mass index and weight loss attempts.

CONTEXT: There are scant data on patterns of multivitamin use among US adults in terms of body mass index (BMI) or whether one is trying to lose weight. OBJECTIVE: To examine multivitamin use and beliefs about multivitamin use among adults according to BMI and to determine whether use by body weight differs if one is trying to lose weight. DESIGN: Cross-sectional multivariate analysis of the HealthStyles consumer survey. The final analytic sample consisted of 2239 women and 1532 men. MAIN OUTCOME MEASURES: Prevalence and odds of multivitamin use by demographic and behavioral characteristics including BMI, use by weight loss intent, and among users, reasons for use. RESULTS: 63.7% of women and 52.9% of men reported multivitamin use (taking 1 or more multivitamin per week). Obese women were less likely than normal-weight women to use multivitamins; no differences according to BMI category were detected for men. Among women who were not trying to lose weight, obese women were less likely than normal-weight women to use multivitamins (odds ratio = 0.63, CI 0.41-0.98). Assessment of reasons for use found that compared among women not trying to lose weight, those trying to lose weight were more likely to report multivitamin use because It is important for my health. CONCLUSIONS: This descriptive analysis adds to the limited literature on multivitamin use according to both body weight and attempting to lose weight. Multivitamin use was common and decreased with increasing BMI. This may be because fewer obese people consider vitamins "important for their health".

Associations between body mass index and the prevalence of low micronutrient levels among US adults.

BACKGROUND: Low micronutrient levels observed with increasing adiposity may result from inadequate nutrient intake and/or alterations in nutrient metabolism. OBJECTIVE: To examine the association between body mass index (BMI) and micronutrient levels among a nationally representative sample of US adults aged > or = 19 years. DESIGN: Using nationally representative cross-sectional data from the National Health and Nutrition Examination Survey III (NHANES III), we examined odds ratios of low micronutrient levels using logistic regression adjusting for covariates. MEASUREMENTS: Nutritional biomarker levels (as indicated by serum levels of total carotenoids, alpha-carotene, beta-carotene, beta-cryptoxanthin, lutein/zeaxanthin, lycopene, vitamin E, vitamin C, selenium, vitamin A, vitamin D, folate, vitamin B12, and red blood cell folate) among men and nonpregnant women, by BMI category. RESULTS: Overweight and obese adults had higher odds of low levels for a number of nutrients compared with normal-weight adults. Odds of being low in multiple micronutrients was most common among overweight and obese premenopausal women. CONCLUSION: These findings underscore the need for further assessment of specific micronutrient inadequacies among persons who are overweight or obese. Specifically, research is needed to determine whether these inadequacies are due to insufficient dietary intake, altered metabolic processes, or both.

Low nutrient intakes among infants in rural Bangladesh are attributable to low intake and micronutrient density of complementary foods.

We assessed the adequacy of nutrient intakes of 135 rural Bangladeshi breast-fed infants 6-12 mo of age and examined nutritional trade-offs due to possible displacement of breast milk by complementary foods. Observers completed 12-h daytime measurements of breast milk and complementary food intakes; data for the previous 12 h were obtained from maternal recall, yielding estimates of total 24-h intakes. On average, infants were mildly wasted (mean +/- SD weight-for-length Z-score = -0.92 +/- 0.88) and moderately stunted (length-for-age Z-score = -1.49 +/- 0.96). Total energy intakes at 6-8 and 9-12 mo were 88 and 86% of absolute energy requirements (kJ/d), 106 and 105% of requirements per kg body weight, and 97 and 94% of requirements per kg median weight-for-length, respectively. Breast milk contributed 78% of energy intake at 6-8 mo and 75% at 9-12 mo. Mean meal frequency and energy density of complementary foods were generally consistent with recommendations, but only small amounts of food were offered. Nevertheless, only 72% of the food energy offered was consumed. Total energy intake was positively correlated with meal frequency, quantity consumed per meal, and energy intake from breast milk, but not with energy density of complementary foods. Energy intake from complementary foods was inversely related to energy intake from breast milk. The diets fell short of recommended intakes for numerous vitamins and minerals. We conclude that although greater intakes of complementary foods were associated with higher total energy intake, micronutrient intake remained low due to the low micronutrient density of the complementary foods consumed and the partial displacement of breast milk.

Behavior-change trials to assess the feasibility of improving complementary feeding practices and micronutrient intake of infants in rural Bangladesh.

This study used simple rapid-assessment techniques to test the feasibility of increasing the consumption of complementary foods by infants by asking mothers to increase meal quantity or frequency or by altering the viscosity/energy density of the food. The feasibility of using micronutrient supplements either added directly to food or administered as liquid drops was also examined. The study was conducted in rural Bangladesh and involved four separate short-term behavioral change trials. Depending on the trial, fieldworkers recruited 30 to 45 infants 6 to 12 months of age. Following recommendations to increase the amount of food provided to infants, the mean intakes from single meals increased from 40 +/- 23 g on day 1 to 64 +/- 30 g on day 7 (p < 0.05). In a second trial, the mean meal frequency increased from 2.2 +/- 1.3 on day 1 to 4.1 +/- 1.3 on day 7 (p < 0.05). Provision of high-energy-density diets, prepared by decreasing viscosity with alpha-amylase or by hand-mashing rice and dhal into a paste before feeding, increased single-meal energy consumption from 54 +/- 35 kcal to 79 +/- 52 kcal or 75 +/- 37 kcal (p < 0.05), respectively. Both types of micronutrient supplements were well accepted and used according to recommendations. In conclusion, it was possible to change short-term child-feeding behaviors to promote increased food intake, mealfrequency, energy density, and micronutrient consumption. Because each of these interventions lasted for only about 1 week, however, the long-term sustainability of these changes is not known. Moreover, the effect of increased feeding of complementary foods on intakes of breastmilk and total daily consumption of energy and nutrients requires further study.
