RESUMO

INTRODUCTION: On January 1, 2017, Philadelphia implemented a beverage excise tax. The study's objective was to determine whether beverage advertising expenditures and the number of beverage ads purchased changed in Philadelphia compared to Baltimore because of this tax. METHODS: Monthly beverage ad expenditures and the number of beverage ads purchased by brand from January 2016 through December 2019 were obtained. Ads were coded as being for taxed or not taxed beverages and analyzed in 2023. The primary outcomes were quarterly taxed beverage ad expenditures and number of ads purchased. A controlled interrupted time series design on segmented linear regression models was used. Models (aggregated and stratified by internet, spot TV, and local radio) compared whether levels and trends in the outcomes changed from pre- to post-tax in Philadelphia compared to Baltimore. RESULTS: There were no significant differences in taxed beverage advertising expenditures between Philadelphia and Baltimore for trends pretax, at implementation, or post-tax. There were 0.13 (95% CI: -0.25, -0.003) fewer quarterly taxed beverage ads purchased per 100 households in Philadelphia versus Baltimore at baseline. Among internet advertising, there were 0.42 (95% CI: -0.77, -0.06) fewer quarterly taxed beverage ads purchased per 100 households in Philadelphia versus Baltimore immediately post-tax. For spot TV ads, the percentage of taxed beverages ads purchased per quarter was greater at baseline in Philadelphia by 28.0 percentage points (95% CI: 1.9, 54.1). CONCLUSIONS: This study found little evidence of changes in mass media advertising on the examined platforms between 2016 and 2019 due to the Philadelphia beverage tax.

RESUMO

BACKGROUND AND OBJECTIVES: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) prevents food insecurity and supports nutrition for more than 3 million low-income young children. Our objectives were to determine the cost-effectiveness of changes to WIC's nutrition standards in 2009 for preventing obesity and to estimate impacts on socioeconomic and racial/ethnic inequities. METHODS: We conducted a cost-effectiveness analysis to estimate impacts from 2010 through 2019 of the 2009 WIC food package change on obesity risk for children aged 2 to 4 years participating in WIC. Microsimulation models estimated the cases of obesity prevented in 2019 and costs per quality-adjusted-life year gained. RESULTS: An estimated 14.0 million 2- to 4-year old US children (95% uncertainty interval (UI), 13.7-14.2 million) were reached by the updated WIC nutrition standards from 2010 through 2019. In 2019, an estimated 62 700 (95% UI, 53 900-71 100) cases of childhood obesity were prevented, entirely among children from households with low incomes, leading to improved health equity. The update was estimated to cost $10 600 per quality-adjusted-life year gained (95% UI, $9760-$11 700). If WIC had reached all eligible children, more than twice as many cases of childhood obesity would have been prevented. CONCLUSIONS: Updates to WIC's nutrition standards for young children in 2009 were estimated to be highly cost-effective for preventing childhood obesity and contributed to reducing socioeconomic and racial/ethnic inequities in obesity prevalence. Improving nutrition policies for young children can be a sound public health investment; future research should explore how to improve access to them.

RESUMO

INTRODUCTION: In 2017, Philadelphia enacted a $0.015 per ounce excise tax on SBs that covered both sugar-sweetened beverages and artificially-sweetened beverages, which reduced purchasing and consumption. This study assessed whether the tax also changed beverage advertising or stocking practices that could influence consumer behavior among stores in Philadelphia, Baltimore, and Philadelphia-adjacent counties not subject to the tax. METHODS: Using a longitudinal difference-in-differences approach, beverage advertising and availability changes were evaluated from 4-month pretax to 6-, 12-, and 24-month post-implementation in small independent stores in Philadelphia (n=34) and Philadelphia-adjacent counties (n=38) versus Baltimore (n=43), a demographically similar city without a tax. Mixed effects models tested whether beverage advertising/availability increased in Philadelphia and surrounding counties after implementation versus Baltimore, included store-level random intercepts, and were stratified by beverage tax status, type, size, and store ZIP code income. Data were collected from 2016 to 2018, and analyses were performed in 2022-2023. RESULTS: SB advertising increased post-tax in Philadelphia (6 months= +1.04 advertisements/store [95% CI=0.27, 1.80]; 12 months= +1.54 [95% CI=0.57, 2.52]; 24 months= +0.91 [95% CI=0.09, 1.72]) relative to Baltimore. This was driven by increased advertising of sweetened beverages in low-income ZIP codes. Marketing of SBs increased significantly in Philadelphia-adjacent counties relative to Baltimore. Although SB availability in Philadelphia did not change, it increased in surrounding county stores (6 months= +0.20 [95% CI=0.15, 0.25]; 12 months= +0.08 [95% CI=0.03, 0.12]) relative to Baltimore. CONCLUSIONS: Marketing of SBs, especially in low-income neighborhoods and in surrounding counties, increased following Philadelphia's beverage tax among small, independent retailers. These increases in advertising might have dampened the tax's effect on purchasing behaviors, although estimated effects on sales remained large.

RESUMO

INTRODUCTION: Calorie labeling of standard menu items has been implemented at large restaurant chains across the U.S. since 2018. The objective of this study was to evaluate the cost effectiveness of calorie labeling at large U.S. fast-food chains. METHODS: This study evaluated the national implementation of calorie labeling at large fast-food chains from a modified societal perspective and projected its cost effectiveness over a 10-year period (2018-2027) using the Childhood Obesity Intervention Cost-Effectiveness Study microsimulation model. Using evidence from over 67 million fast-food restaurant transactions between 2015 and 2019, the impact of calorie labeling on calorie consumption and obesity incidence was projected. Benefits were estimated across all racial, ethnic, and income groups. Analyses were performed in 2022. RESULTS: Calorie labeling is estimated to be cost saving; prevent 550,000 cases of obesity in 2027 alone (95% uncertainty interval=518,000; 586,000), including 41,500 (95% uncertainty interval=33,700; 50,800) cases of childhood obesity; and save $22.60 in healthcare costs for every $1 spent by society in implementation costs. Calorie labeling is also projected to prevent cases of obesity across all racial and ethnic groups (range between 126 and 185 cases per 100,000 people) and all income groups (range between 152 and 186 cases per 100,000 people). CONCLUSIONS: Calorie labeling at large fast-food chains is estimated to be a cost-saving intervention to improve long-term population health. Calorie labeling is a low-cost intervention that is already implemented across the U.S. in large chain restaurants.

RESUMO

INTRODUCTION: The federal Child and Adult Care Food Program (CACFP) improves nutrition and reduces food insecurity among young children by helping cover the food costs for child care providers and families. This nationwide study evaluated the extent and predictors of the CACFP's utilization among licensed child care centers to identify opportunities for expanding CACFP nutrition support. METHODS: Administrative data from the CACFP and child care licensing agencies in 47 states and District of Columbia were compiled and geocoded for 93,227 licensed child care centers. CACFP participation was predicted using a multivariable Bayesian spatial logistic regression model in the sample of low-income areas to target CACFP eligible child care centers. Data were collected in 2020-2021 and analyzed in 2022. RESULTS: Of all licensed child care centers, 36.5% participated in the CACFP, ranging from 15.2% to 65.3% across states; when restricted to low-income areas, 57.5% participated (range, 15.7%-85.7%). Income differences did not explain the large variation in CACFP participation rates across states. Having at least three CACFP sponsoring agencies per state predicted a 38% higher probability of CACFP participation (OR=1.38; 95% Credible Interval=1.08-1.78). CONCLUSIONS: Currently CACFP participation rates among licensed child care centers point to program underutilization and unequal access, particularly in some states and regions. Work at the federal and state levels is warranted to expand participation in the program, above all in low-income areas, so that more young children could eat healthfully with the CACFP.

RESUMO

INTRODUCTION: Amid the successes of local sugar-sweetened beverage (SSB) taxes, interest in state-wide policies has grown. This study evaluated the cost effectiveness of a hypothetical 2-cent-per-ounce excise tax in California and its implications for population health and health equity. METHODS: Using the Childhood Obesity Intervention Cost-Effectiveness Study microsimulation model, tax impacts on health, health equity, and cost effectiveness over 10 years in California were projected, both overall and stratified by race/ethnicity and income. Expanding on previous models, differences in the effect of intake of SSBs on weight by BMI category were incorporated. Costing was performed in 2020, and analyses were conducted in 2021-2022. RESULTS: The tax is projected to save $4.55 billion in healthcare costs, prevent 266,000 obesity cases in 2032, and gain 114,000 quality-adjusted life years. Cost-effectiveness metrics, including cost/quality-adjusted life year gained, were cost saving. Spending on SSBs was projected to decrease by $33 per adult and $26 per child overall in the first year. Reductions in obesity prevalence for Black and Hispanic Californians were 1.8 times larger than for White Californians, and reductions for adults with lowest incomes (<130% Federal Poverty Level) were 1.4 times the reduction among those with highest incomes (>350% Federal Poverty Level). The tax is projected to save $112 in obesity-related healthcare costs per $1 invested. CONCLUSIONS: A state-wide SSB tax in California would be cost saving, lead to reductions in obesity and improvement in SSB-related health equity, and lead to overall improvements in population health. The policy would generate more than $1.6 billion in state tax revenue annually that can also be used to improve health equity.

RESUMO

The federal Child and Adult Care Food Program (CACFP) improves nutrition and reduces food insecurity for young children while helping cover food costs for care providers and families. Despite its important benefits, the program is underutilized. This report uses qualitative interviews with state CACFP administrators representing 28 states to explore federal and state policies and practices that support or discourage CACFP participation among licensed child care centers. We report on successful approaches to program outreach and administration, barriers that make CACFP participation challenging, and recommendations to expand access to CACFP for eligible child care providers and the populations they serve.

RESUMO

Much of the chronic disease burden in the U.S. population can be traced to poor diet. There has been a sustained focus on influencing children's diets and encouraging healthier eating habits by changing policies for what foods and beverages can be served to children through large federally-funded nutrition assistance programs. Yet without attention to how nutrition policies are implemented, and the surrounding context for these policies, these policy changes may not have the intended results. In this perspective, we used Bullock et al.'s (2021) Process Model of Implementation from a Policy Perspective to analyze how the complexities of the implementation process of large-scale nutrition policies can dilute potential health outcomes. We examine the Child and Adult Care Food Program (CACFP), a federal program focused on supporting the provision of nutritious meals to over 4 million children attending childcare, as a case study. We examine how the larger societal contexts of food insecurity, attitudes towards the social safety net, and a fragmented childcare system interact with CACFP. We review the "policy package" of CACFP itself, in terms of its regulatory requirements, and the various federal, state, and local implementation agencies that shape CACFP's on-the-ground implementation. We then review the evidence for how each component of the CACFP policy implementation process impacts uptake, costs, feasibility, equity, and effectiveness at improving children's nutrition. Our case study demonstrates how public health researchers and practitioners must consider the complexities of policy implementation processes to ensure effective implementation of nutrition policies intended to improve population health.

RESUMO

OBJECTIVE: This study aimed to estimate the 10-year cost-effectiveness of school-based BMI report cards, a commonly implemented program for childhood obesity prevention in the US where student BMI is reported to parents/guardians by letter with nutrition and physical activity resources, for students in grades 3 to 7. METHODS: A microsimulation model, using data inputs from evidence reviews on health impacts and costs, estimated: how many students would be reached if the 15 states currently measuring student BMI (but not reporting to parents/guardians) implemented BMI report cards from 2023 to 2032; how many cases of childhood obesity would be prevented; expected changes in childhood obesity prevalence; and costs to society. RESULTS: BMI report cards were projected to reach 8.3 million children with overweight or obesity (95% uncertainty interval [UI]: 7.7-8.9 million) but were not projected to prevent any cases of childhood obesity or significantly decrease childhood obesity prevalence. Ten-year costs totaled $210 million (95% UI: $30.5-$408 million) or $3.33 per child per year with overweight or obesity (95% UI: $3.11-$3.68). CONCLUSIONS: School-based BMI report cards are not cost-effective childhood obesity interventions. Deimplementation should be considered to free up resources for implementing effective programs.

RESUMO

Importance: Taxes on sweetened beverages are being implemented around the globe; an understanding of these taxes on individual-level behavior is necessary. Objective: To evaluate the degree to which the sweetened beverage tax in Philadelphia, Pennsylvania, was associated with changes in beverage prices and individual-level purchasing over time at a national pharmacy chain in Philadelphia compared with Baltimore, Maryland. Design, Setting, and Participants: Using a difference-in-differences approach and generalized linear mixed models, this cohort study examined beverage purchases made by loyalty cardholders at a national chain pharmacy retailer with stores in Philadelphia and Baltimore (control city) from before tax to after tax. Beverage sales (in US dollars) were linked by unique loyalty card numbers to enable longitudinal analyses. Data were collected from January 1, 2015, through December 31, 2017 (2 years before tax and 1 year after tax); data analyses were conducted from January through October 2022. Exposure: Implementation of Philadelphia's 1.5 cents/oz tax on sweetened beverages. Main Outcomes and Measures: The outcomes were the change in mean beverage price per-ounce and mean beverage volume purchased per cardholder transaction. Individual-level point-of-sale scanner data from all beverage purchases were analyzed. Results: A total of 1188 unique beverages were purchased from the same stores before tax and after tax. There were 231 065 unique cardholders in Philadelphia and 82 517 in Baltimore. Mean prices of taxed beverages (n = 2 094 220) increased by 1.6 (95% CI, 1.3-2.0) cents/oz (106.7% pass-through) in Philadelphia compared with Baltimore from before tax to after tax. Philadelphia cardholders purchased 7.8% (95% CI -8.1% to -7.5%) fewer ounces of taxed beverages and 1.1% (95% CI, 0.6%-1.7%) more ounces of nontaxed beverages per transaction. Taxed beverages made up a smaller percentage of cardholders' overall beverage purchases after tax (-13.4% [95% CI, -14.2% to -12.6%]), while nontaxed beverages made up a larger share (9.3% [95% CI, 7.7%-10.7%]). Conclusions and Relevance: In this longitudinal cohort study of the Philadelphia beverage tax, the tax was completely passed through to prices and was associated with a 7.8% decline in ounces of taxed beverages purchased at a national pharmacy chain.

RESUMO

OBJECTIVE: Though prevalent, weight-based discrimination is understudied and has been linked to disordered eating behaviors (DEB) among adolescents and adults. Sexual minority populations experience elevated risk of DEB, but little is known about the role of weight discrimination in this elevated risk. METHODS: Participants were 1257 sexual minority women and men (ages 18-31 years) in the US Growing Up Today Study cohort. We examined cross-sectional associations between weight discrimination victimization and three DEB in the past year: unhealthy weight control behaviors, overeating, and binge eating. Generalized estimating equations, adjusted for potential confounders, were used to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs). RESULTS: Three in 10 participants (31%) reported weight-based discrimination victimization. Sexual minority young adults who reported weight-based discrimination had greater relative prevalence of unhealthy weight control behaviors (PR [95% CI]: 1.92 [1.35, 2.74]), overeating (3.15 [2.24, 4.44]), and binge eating (3.92 [2.51, 6.13]), compared with those who reported no weight-based discrimination. Associations with overeating and binge eating remained significant after adjusting for BMI. DISCUSSION: The role of weight-based discrimination, and its intersections with other forms of stressors for sexual minority young adults, must be included in efforts to advance eating disorder prevention for this underserved population. PUBLIC SIGNIFICANCE: Three in 10 sexual minority young adults in this study had experienced weight-based discrimination, a common but understudied form of discrimination. Sexual minority young adults who experienced weight-based discrimination were at greater risk of disordered eating behaviors than those who had not experienced weight-based discrimination. These findings suggest that weight-based discrimination may be an important-and preventable-risk factor for disordered eating behaviors among sexual minority young adults.

RESUMO

BACKGROUND: This study explored reasons for the adoption of a policy to distribute report cards to parents about children's weight status ("BMI report cards") in Massachusetts (MA) public schools in 2009 and the contextual factors influencing the policy removal in 2013. METHODS: We conducted semi-structured, qualitative interviews with 15 key decision-makers and practitioners involved with implementing and de-implementing the MA BMI report card policy. We analyzed interview data using a thematic analytic approach guided by the Consolidated Framework for Implementation Research (CFIR) 2.0. RESULTS: Primary themes were that (1) factors other than scientific evidence mattered more for policy adoption, (2) societal pressure spurred policy adoption, (3) problems with the policy design contributed to inconsistent implementation and dissatisfaction, and (4) media coverage, societal pressure, and organizational politics and pressure largely prompted de-implementation. CONCLUSIONS: Numerous factors contributed to the de-implementation of the policy. An orderly process for the de-implementation of a policy in public health practice that manages drivers of de-implementation may not yet exist. Public health research should further focus on how to de-implement policy interventions when evidence is lacking or there is potential for harm.

RESUMO

OBJECTIVE: The federal Child and Adult Care Food Program (CACFP) sets minimum nutrition and portion size standards for meals served in participating childcare programs. CACFP has been associated with more nutritious meals served. It is unclear, however, whether CACFP results in children's dietary intake being aligned with national recommendations. We assess whether children's dietary intake in CACFP-participating childcare centres meets benchmarks set by the Dietary Guidelines for Americans (DGA). DESIGN: This is a cross-sectional study. We used direct observation to estimate quantities of foods/beverages served and consumed per child. Mean amounts served per child per day were compared with CACFP portion size requirements for each component (fruits, vegetables, milk and meat/meat alternate). Mean amounts of foods/beverages consumed were compared with DGA recommendations (energy content, fruits, vegetables, whole/refined grains, dairy, protein and added sugars). One sample t-tests evaluated if quantities served and consumed were different from CACFP and DGA standards, respectively. SETTING: Six CACFP-participating childcare centres. PARTICIPANTS: 2-5 year-old children attending childcare. RESULTS: We observed forty-six children across 166 child meals. Most meals served met CACFP nutrition standards. Compared with CACFP portion size standards, children were served more grains at breakfast and lunch; more fruits/vegetables at lunch but less at breakfast and snack and less dairy at all eating occasions. Compared with DGA recommendations, children under-consumed every food/beverage category except grains during at least one eating occasion. CONCLUSIONS: Children were served quantities of foods/beverages mostly consistent with CACFP portion size requirements, but had sub-optimal intake relative to DGA. More research is needed to help children consume healthy diets in childcare.

RESUMO

CONTEXT: The Child and Adult Care Food Program (CACFP) is a federal nutrition program that supports young children's nutrition. Its potential impacts on child well-being have not been summarized. OBJECTIVE: The objective of this review was to summarize the evidence for the impact of CACFP on children's diet quality, weight status, food insecurity, and cognitive development. DATA SOURCES: Databases searched included MEDLINE, CAB Abstracts, Web of Science Core Collection, ERIC, PsycInfo, Dissertations & Theses Global (Proquest), EconLit, NBER, and the USDA's Economic Research Service (ERS), from database inception to November 12, 2021. Studies were included if the sample drew from child care programs serving children between the ages of 2 years and 18 years and if a comparison group of nonparticipating programs was included. DATA EXTRACTION: Two reviewers independently extracted data on study design, year(s) of data collection, region, sample size, participant demographics, outcomes, and risk of bias. DATA ANALYSIS: Due to the heterogeneity of the studies, a narrative synthesis was used. RESULTS: Nineteen articles were reviewed, most of which had been published since 2012. Seventeen used cross-sectional designs. Twelve evaluated foods and beverages served; 4 evaluated dietary intake; 4 evaluated the child care nutrition environment; 2 evaluated food insecurity, 1 evaluated weight status; none evaluated cognitive outcomes. Studies typically found either a small beneficial association with CACFP or no significant association. CONCLUSION: Currently, evidence for an association between CACFP and children's health is inconclusive, though it is slightly suggestive of a benefit for some dietary quality outcomes. More research, with stronger study designs, is needed. SYSTEMATIC REVIEW REGISTRATION: A protocol for this systematic review was registered with the PROSPERO systematic review protocol registry (PROSPERO 2021 CRD42021254423).

RESUMO

INTRODUCTION: Large portions, which can lead people to eat more, are becoming increasingly common in U.S. restaurants. This study tested whether portion-size descriptions on menus and different pricing strategies influence the selection of smaller portion sizes. STUDY DESIGN: This was a 4 × 2 between-subjects online randomized controlled experiment. SETTING/PARTICIPANTS: This was an online simulated menu-ordering study conducted in 2021 among 2,205 U.S. adults. INTERVENTION: Adults viewed a fast-casual and full-service menu with entrées available in 2 sizes and ordered an entrée from each. Participants were randomized to view 1 of 4 portion-size descriptors (smaller/larger portion): (1) no descriptor/large (control), (2) standard/large, (3) just right/large, and (4) no descriptor/hearty. Participants were also randomized to either linear (i.e., reduced price=50% larger portion's price) or nonlinear pricing (i.e., reduced price=70% larger portion's price) (4 × 2 factorial design). MAIN OUTCOME MEASURES: In 2022, logistic regression models were used to analyze whether the interventions increased the likelihood of choosing a reduced portion. RESULTS: Regardless of pricing scheme, participants in the standard/large condition selected reduced portions by 10 (95% CI=0.04, 0.16) and 13 (95% CI=0.07, 0.18) percentage points more than those in the control condition (fast-casual and full-service menus, respectively). Selection of reduced portions in the just right/large condition increased by 9 (95% CI=0.04, 0.15) and 8 (95% CI=0.02, 0.14) percentage points. For the fast-casual menu, keeping portion-size descriptors constant, participants ordered a reduced portion by 5 percentage points more with nonlinear pricing than with linear pricing. CONCLUSIONS: Portion-size descriptions on restaurant menus, even with nonlinear pricing, are a low-cost strategy to promote the selection of lower-calorie, smaller portions without restricting choice.

RESUMO

OBJECTIVE: We sought to evaluate the use of behavioral economics approaches to promote the carrying of epinephrine auto-injectors (EAIs) among adolescents with food allergies. We hypothesized that adolescents who receive frequent text message nudges (Intervention 1) or frequent text message nudges plus modest financial incentives (Intervention 2) would be more likely to carry their epinephrine than members of the usual care control group. METHODS: We recruited 131 adolescents ages 15 to 19 with a food allergy and a current prescription for epinephrine to participate in a cohort multiple randomized controlled trial. Participants were randomly assigned to participate in Intervention 1, Intervention 2, or to receive usual care. The primary outcome was consistency of epinephrine-carrying, measured as the proportion of checkpoints at which a participant could successfully demonstrate they were carrying their EAI, with photo-documentation of the device. RESULTS: During Intervention 1, participants who received the intervention carried their EAI 28% of the time versus 38% for control group participants (P = .06). During Intervention 2, participations who received the intervention carried their EAI 45% of the time versus 23% for control group participants (P = .002). CONCLUSIONS: Text message nudges alone were unsuccessful at promoting EAI-carrying but text message nudges combined with modest financial incentives almost doubled EAI-carriage rates among those who received the intervention compared with the control group. However, even with the intervention, adolescents with food allergies carried their EAI <50% of the time. Alternative strategies for making EAIs accessible to adolescents at all times should be implemented.

RESUMO

BACKGROUND: This study reports the outcomes of Communities for Healthy Living (CHL), a cluster randomized obesity prevention trial implemented in partnership with Head Start, a federally-funded preschool program for low-income families. METHODS: Using a stepped wedge design, Head Start programs (n = 16; Boston, MA, USA) were randomly assigned to one of three intervention start times. CHL involved a media campaign and enhanced nutrition support. Parents were invited to join Parents Connect for Healthy Living (PConnect), a 10-week wellness program. At the beginning and end of each school year (2017-2019), data were collected on the primary outcome of child Body Mass Index z-score (BMIz) and modified BMIz, and secondary outcomes of child weight-related behaviors (diet, physical activity, sleep, media use) and parents' weight-related parenting practices and empowerment. Data from 2 years, rather than three, were utilized to evaluate CHL due to the COVID-19 pandemic. We used mixed effects linear regression to compare relative differences during intervention vs. control periods (n = 1274 vs. 2476 children) in (1) mean change in child BMIz and modified BMIz, (2) the odds of meeting child health behavior recommendations, (3) mean change in parenting practices, and (4) mean change in parent empowerment. We also compared outcomes among parents who chose post-randomization to participate in PConnect vs. not (n = 55 vs. 443). RESULTS: During intervention periods (vs. control), children experienced greater increases in BMIz and modified BMIz (b = 0.06, 95% CI = 0.02,0.10; b = 0.07, 95% CI = 0.03, 0.12), yet were more likely to meet recommendations related to three of eight measured behaviors: sugar-sweetened beverage consumption (i.e., rarely consume; Odds Ratio (OR) = 1.5, 95% CI = 1.2,2.3), water consumption (i.e., multiple times per day; OR = 1.6, 95% CI = 1.2,2.3), and screen time (i.e., ≤1 hour/day; OR = 1.4, 95% CI = 1.0,1.8). No statistically significant differences for intervention (vs. control) periods were observed in parent empowerment or parenting practices. However, parents who enrolled in PConnect (vs. not) demonstrated greater increases in empowerment (b = 0.17, 95% CI = 0.04,0.31). CONCLUSIONS: Interventions that emphasize parent engagement may increase parental empowerment. Intervention exposure was associated with statistically, but not clinically, significant increases in BMIz and increased odds of meeting recommendations for three child behaviors; premature trial suspension may explain mixed results.

RESUMO

Responding to the COVID-19 pandemic, the American Rescue Plan (2021) allowed state agencies of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) the option of temporarily increasing the Cash-Value Benefit (CVB) for fruit and vegetable (FV) purchases. To examine the impact of this enhancement on WIC caregiver experience, the MA WIC State Office invited 4600 randomly selected MA WIC caregivers to complete an online survey (February-March 2022). Eligible adults had at least one child, had been enrolled at least a year, and were aware of the increase. Of those who opened the screener (n = 545), 58.9% completed it (n = 321). We calculated the frequencies of reporting increased FV outcomes and tested whether responses differed by race/ethnicity, market access, and food security. Most caregivers perceived the CVB increase to benefit FV purchasing (amount and quality, 71.0% and 55.5%), FV consumption (offered to children and personally consumed, 70.1% and 63.2%), and satisfaction with the WIC food package (37.1% reported improved satisfaction, pre- vs. post-increase). Probability of reporting improved outcomes was not found to differ by race/ethnicity, market access, or food security. CVB increases may pose important implications for dietary behaviors and satisfaction with WIC. Policymakers should consider making this increase permanent.

RESUMO

With diet-related chronic diseases being the largest contributors to U.S. morbidity and mortality, identifying population-level strategies to promote healthier diets is essential. Intervention during early childhood may be particularly important. The Child and Adult Care Food Program (CACFP), a federal nutrition assistance program in the U.S. that supports serving meals and snacks in child care settings, reaches millions of U.S. children. Recent 2017 updates to CACFP's meal patterns were meant to improve the nutritional quality of food served through CACFP by providing more whole grains, fruit, and vegetables. In this study, we used a natural experimental, longitudinal study of child care centers participating in CACFP compared to nonparticipating centers to assess whether the quality of food and beverages served (per menu analysis) improved following the CACFP meal pattern changes. While we found that CACFP centers were more likely to meet several key nutrition standards in comparison to non-CACFP centers overall, there were no differences in menu quality from before to after the 2017 standards change between CACFP and non-CACFP centers. Nutrition standards for CACFP may need to be further strengthened with adequate financial and technical support given to child care programs for effective implementation.
