RESUMEN

Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participants faced unprecedented challenges during the coronavirus disease 2019 (COVID-19) pandemic including financial concerns, a national infant formula shortage, and rising food costs. To mitigate these challenges, the United States Department of Agriculture implemented WIC program waivers and flexibilities aiming to simplify program operations (e.g., remote appointments and food package substitutions). However, little is known about WIC participants' perceptions of these changes and their impact on in-store benefit redemption. As such, this study aimed to characterize how pandemic-related events impacted Delaware WIC participants' shopping experiences and program perceptions. The authors conducted semi-structured interviews with 51 WIC participants in Wilmington, Delaware. Survey measures included demographic questions, the Hunger Vital Sign, and open-ended questions regarding WIC program participation experiences during the pandemic. Data were analyzed using a hybrid inductive and deductive coding approach. The results demonstrate that WIC participants benefitted from the pandemic program's flexibilities. However, they continued to experience burdensome shopping trips as well as concerns about their ability to feed their families due to infant formula shortages and inflation. These findings indicate the importance of extending existing WIC flexibilities and providing continued support for both participants and WIC-authorized retailors.

RESUMEN

This study aimed to identify barriers and facilitators to discussing parent mental health within child health care for parents of children with congenital heart disease (CHD). Seventy-nine parents of young children with CHD who received care across 40 hospitals in the United States responded to questions about barriers and facilitators to discussing their mental health with their child's health care providers. Responses were analyzed using qualitative research methods. Parents described multiple barriers: (1) belief that parent mental health support was outside the care team's scope of practice, (2) perceived expectation to "stay strong," (3) fear of negative judgment or repercussion, (4) individual preferences for communication/support, (5) desire to maintain care resources on their child, (6) perceived need to compartmentalize emotions, and (7) negative reactions to past emotional disclosure. Parents also described several facilitators: (1) confidence in the care team's ability to provide support, (2) intentional efforts by the care team to provide support, (3) naturally extroverted tendencies, and (4) developing personal connections with health care providers. It is important that health care providers normalize the impact of child illness on the family and create an environment in which parents feel comfortable discussing mental health challenges.

RESUMEN

This review identifies the most promising intervention strategies for promoting the purchase and consumption of healthier items within U.S. grocery retail settings, with a particular focus on those strategies that may be most effective when implemented within SNAP-authorized retail settings. Searches of nine electronic databases, as well as forward and backward searches, yielded 1942 studies. After being screened, 73 peer-reviewed academic articles were identified for inclusion. Of these, 33 analyzed single-component interventions, while 40 assessed multi-component interventions. The following unique intervention types were considered as evaluated in these studies for their ability to increase healthy item purchasing and consumption: (1) nutrition scoring, (2) nutritional messaging, (3) non-nutritional messaging, (4) endcaps and secondary placement, (5) point-of-sale interventions, (6) increased stocking, (7) food tasting and demonstrations, (8) nutrition education, and (9) placement on shelf interventions. Nutritional scoring and nutritional messaging emerged as the most rigorously tested and effective intervention strategies. Other strategies warrant more research attention. Simple intervention strategies, as opposed to complex ones, yield the most successful results and minimize shopper burden. Therefore, these strategies should be reviewed for policy implementation within SNAP-authorized grocery retailers.

RESUMEN

Recent changes to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Cash-Value Benefit (CVB), which provides participants with money to spend on fruits and vegetables, have the potential to reduce disparities in healthy food access and food insecurity that were exacerbated by the COVID-19 pandemic. However, few studies have examined how the changes to the CVB allotment that occurred during the pandemic influenced WIC participants' perceptions of the benefit or their fruit and vegetable purchasing and consumption. To address this gap, we conducted semi-structured interviews with 51 WIC participants in Wilmington, Delaware. Survey measures included demographic questions, the Hunger Vital Sign food insecurity screener, and open-ended questions regarding perceptions of the CVB increase and its influence on participants' fruit and vegetable purchasing and consumption. Data were analyzed using a hybrid inductive and deductive coding approach. The results demonstrate that higher CVB allotments increased WIC participants' purchasing and consumption of fruits and vegetables, increased the frequency of their shopping occasions, and enhanced their dietary variety. Our findings also suggest that WIC participants highly value the increased CVB. Consequently, maintaining the increased CVB allotment could improve the nutritional outcomes of low-income mothers, infants, and children participating in WIC.

RESUMEN

OBJECTIVE: Despite evidence that social support is beneficial for people living with opioid use disorders (OUDs), research has yet to investigate whether social support within certain relationships is more or less effective. The current study examined whether social support, relationship closeness with a disclosure partner, and/or the history of joint substance use between participants and disclosure partners affect commitment to sobriety among people receiving medications for OUD. METHOD: Over a period of 3 months (two time points), participants taking OUD medications took part in a mixed-methods egocentric social network study exploring their relationships with disclosure partners before and following OUD disclosure (i.e., first telling a disclosure partner about one's OUD history or treatment). Data included 131 disclosure events/relationships clustered within 106 participants. RESULTS: Greater relationship closeness was associated with increased commitment to sobriety over time. Further, significant interactions were found between social support and disclosure partner closeness, partner closeness and history of joint substance use, and social support and history of joint substance use. Higher social support was associated with greater commitment to sobriety among those disclosing to close partners. In contrast, receiving social support or disclosing to a close partner with whom there was a history of joint substance use was associated with decreased commitment to sobriety. CONCLUSIONS: Findings highlight the complexities of social support among people in treatment for OUD and demonstrate that relationship closeness and a history of joint substance use with a disclosure partner may be important factors to consider before disclosure.

RESUMEN

Environment and setting have a large influence on matters of population health, and college is a critical place for students, shaping both health and education. College students across the nation were impacted by the COVID-19 pandemic, and changes at universities left many anxious, isolated, and coping with social, emotional, and educational impacts. Objective: To perform a data analysis of the qualitative responses garnered through the Student Return to Campus Survey administered at the University of Delaware (UD) in Spring 2020, and to identify common themes of student experiences and priorities during the pandemic years to inform future recommendations for health crisis management. Methods: The study utilized secondary data analysis from an online student experience survey of 2,941 Freshman, Sophomore, and Junior students from the 2020-2021 academic year. Results: Qualitative analysis revealed a set of common outstanding themes influencing the college pandemic experience, including: Quality and Accessibility of Education in a Virtual Learning Environment; Quality of Student Life; Mental Health During the Pandemic; Thoughts and Attitudes About Vaccination Policies, Masking, Testing, and COVID Guidelines; Priorities and Considerations About the Return to Campus; and Overall Feelings About the Pandemic at UD. Conclusions: Student experiences were influenced by academic, social, emotional, and financial factors, which were often described with great intensity, and were at times contradictory. Students emphasized struggles with transitioning to and with virtual learning, the quality of campus resources, financial responsibilities, family health, and personal health. The results also shed light on the importance of communication with the campus community and the desire for students to express opinions during a crisis. Health Policy Implications: The results of this study have implications for crisis management for college campuses and planning for future responses to unanticipated events and ongoing COVID-19 mitigation efforts.

RESUMEN

BACKGROUND: Caregivers of children with autism are more likely to experience parenting stress than parents of neurotypical children. Research on parenting stress focuses on partnered caregivers and little is known about the comparative social support experienced by single caregivers. AIM: To explore differences in perceived social support between single versus partnered caregivers of adolescent and adult children on the autism spectrum. METHODS AND PROCEDURES: A cross-sectional, quantitative study using the ENRICHD Social Support Instrument (ESSI) as a measure of perceived social support. Univariate and multivariable analyses were conducted to examine the association between caregiver relationship status and perceived social support. OUTCOMES AND RESULTS: There were statistically significant associations between relationship status and perceived social support, with single caregivers perceiving less social support than partnered caregivers (p < .001). CONCLUSIONS AND IMPLICATIONS: Single caregivers of adolescent and adult children on the autism spectrum perceive less social support than partnered caregivers. Service providers should routinely evaluate the support access of this single caregivers and target support services to address the distinct needs of this population.

RESUMEN

OBJECTIVE: This article characterizes the educational needs of parents following fetal or neonatal congenital heart disease (CHD) diagnosis and generates recommendations for meeting these needs. STUDY DESIGN: Online crowdsourcing methods were used to collect qualitative data from 95 parents of children with CHD regarding their needs for education and preparation following fetal or neonatal diagnosis. Data were analyzed using qualitative methods and themes were organized around the substructure of met and unmet needs. RESULTS: Two themes represented consistently met needs, whereas 10 themes represented needs that were either inconsistently met or consistently unmet. Parents reported needing more information about social, emotional, and financial supports, preparation for long-term care, and guidance toward reputable online resources. Parents also provided recommendations for meeting these needs. CONCLUSION: Parents' needs for education and preparation following CHD diagnosis are much broader in scope than what they currently receive. Addressing these may support parental coping and active participation in medical decision-making. KEY POINTS: · CHD counseling after diagnosis may provide opportunities to promote parents' mental health.. · Guidelines recommend that this counseling should include emotional and decision-making support, however, it is unclear what parents actually receive.. · This study found that parents' needs for education and preparation following CHD diagnosis are much broader in scope than what they currently receive..

RESUMEN

Disparities in healthy food access and consumption are a major public health concern. This study reports the findings from a two-year randomized control trial conducted at 77 farmers' markets (FMs) in 13 states and the District of Columbia that sought to understand the impact of fruit and vegetable (FV) incentive vouchers, randomly issued at varied incentive levels to Supplemental Nutrition Assistance Program (SNAP) recipients, for use at FMs. Measures included FV and overall household food purchasing; FV consumption; food insecurity; health status; market expenditure; and demographics. A repeated-measures mixed-effects analysis and the Complier Average Causal Effect (CACE) were used to examine outcomes. Despite 82% reporting food insecurity in the prior year, the findings showed that financial incentives at FMs had statistically significant, positive effects on FV consumption; market expenditures increased with added incentives. SNAP recipients receiving an incentive of USD 0.40 for every USD 1.00 in SNAP spent an average of USD 19.03 per transaction, while those receiving USD 2 for every USD 1 (2:1) spent an average of USD 36.28 per transaction. The data showed that the incentive program at the highest level (2:1) maximally increased SNAP FM expenditure and FV consumption, increasing the latter by 0.31 daily cups among those who used their incentive (CACE model).

RESUMEN

OBJECTIVE: In 2019, California and Wilmington, Delaware' implemented policies requiring healthier default beverages with restaurant kids' meals. The current study assessed restaurant beverage offerings and manager perceptions. DESIGN: Pre-post menu observations were conducted in California and Wilmington. Observations of cashiers/servers during orders were conducted pre-post implementation in California and post-implementation in Wilmington. Changes in California were compared using multilevel logistic regression and paired t tests. Post-implementation, managers were interviewed. SETTING: Inside and drive-through ordering venues in a sample of quick-service restaurants in low-income California communities and all restaurants in Wilmington subject to the policy, the month before and 7-12 months after policy implementation. PARTICIPANTS: Restaurant observations (California n 110; Wilmington n 14); managers (California n 75; Wilmington n 15). RESULTS: Pre-implementation, the most common kids' meal beverages on California menus were unflavoured milk and water (78·8 %, 52·0 %); in Wilmington, juice, milk and sugar-sweetened beverages were most common (81·8 %, 66·7 % and 46·2 %). Post-implementation, menus including only policy-consistent beverages significantly increased in California (9·7 % to 66·1 %, P < 0·0001), but remained constant in Wilmington (30·8 %). During orders, cashiers/servers offering only policy-consistent beverages significantly decreased post-implementation in California (5·0 % to 1·0 %, P = 0·002). Few managers (California 29·3 %; Wilmington 0 %) reported policy knowledge, although most expressed support. Most managers wanted additional information for customers and staff. CONCLUSIONS: While the proportion of menus offering only policy-consistent kids' meal default beverages increased in California, offerings did not change in Wilmington. In both jurisdictions, managers lacked policy knowledge, and few cashiers/servers offered only policy-consistent beverages. Additional efforts are needed to strengthen implementation of kids' meal beverage policies.

RESUMEN

BACKGROUND: Parents of children with congenital heart disease (CHD) exhibit high rates of mental health difficulties, which can influence child developmental and behavioural outcomes. While extensive research has focused on CHD-related stressors that contribute to parental mental health difficulties, few studies have investigated parental coping strategies that may mitigate or heighten risk. This study aimed to identify parental coping strategies following diagnosis of CHD and compare use of coping strategies among different groups (mothers vs. fathers; prenatal vs. postnatal diagnosis). METHODS: A diverse sample of 34 parents (20 mothers and 14 fathers) of young children with CHD participated in semistructured interviews focused on their responses to CHD-related stressors. Coping strategies were identified from qualitative data and categorized according to the COPE Inventory, an instrument that assesses common adult responses to stress. Coping strategies deemed as unique to parenting a critically ill child were identified. χ2 and independent sample t tests evaluated group differences. RESULTS: Parents described using between 1 and 10 different adaptive and maladaptive strategies measured by the COPE Inventory. Most parents (82.35%) also described coping strategies that may be unique to parenting a critically ill child. Mothers were more likely than fathers to report a focus on and venting of emotions (70% vs. 21.43%) and behavioural disengagement (25% vs. 0%). Compared with parents receiving a postnatal CHD diagnosis, those receiving a prenatal diagnosis described a greater variety of coping strategies (6.23 vs. 4.52) and more often reported positive reinterpretation and growth (69.23% vs. 14.29%), behavioural disengagement (38.46% vs. 0%) and denial (38.46% vs. 0%). CONCLUSIONS: Parents of children with CHD utilize a variety of coping strategies, some of which are maladaptive. Interventions tailored to the needs of mothers and fathers of young children with CHD, including those receiving a postnatal diagnosis, are needed to promote adaptive coping and optimize family psychosocial outcomes.

RESUMEN

INTRODUCTION: Methadone and buprenorphine/naloxone medications are among the most effective treatment options for opioid use disorders, yet many people remain misinformed about their benefits and hold negative perceptions about the use of medications to treat opioid use disorders. Such perceptions, especially negative perceptions based on misinformation, may be especially harmful or stigmatizing within the context of disclosure (i.e., telling another about one's opioid use disorder history or treatment), inhibiting important recovery outcomes and sources of social support. METHODS: Therefore, using the Disclosure Process Model as a framework, the current study seeks to characterize and compare participants' perceptions of stigmatizing reactions to their disclosures of MOUD use that stem from misinformation about methadone or buprenorphine/naloxone. Participants included people who are actively receiving MOUD as treatment. RESULTS: Results suggest that participants (N = 52) receiving both types of medications experienced similar stigmatizing reactions to disclosures. Participants also reported treatment consequences of misinformed reactions to their disclosure, such as dropping out of support groups (e.g., Narcotics Anonymous) or prematurely ending their medication use. Further, the paper provides participants' recommendations for avoiding or managing misinformed disclosure reactions. CONCLUSIONS: Short-term intervention efforts may promote strategies to manage misinformation, equipping individuals to respond to misinformation surrounding their medication use. Long-term interventions may target misinformation about methadone and buprenorphine/naloxone medications to increase health literacy, reduce stigma, and combat cultural ambivalence within communities, as well as promote recovery among people receiving medications for opioid use disorder.

RESUMEN

INTRODUCTION: Despite UN recommendations to monitor food insecurity using the Food Insecurity Experience Scale (FIES), to date there are no published reports of its validity for The Bahamas, nor have prevalence rates of moderate or severe food insecurity been reported for the remote island nation. At the same time, food security is a deep concern, with increasing incidence of natural disasters and health concerns related to diet-related disease and dietary quality plaguing the nation and its food system. This article aims to examine the validity of the FIES for use in The Bahamas, the prevalence of moderate and severe food insecurity, and the sociodemographic factors that contribute to increased food insecurity. METHODS: The FIES survey was administered by randomized and weighted landline telephone survey in Nassau in The Bahamas to 1000 participants in June and July 2017. The Rasch modelling procedure was applied to examine tool validity and prevalence of food insecurity. Equating procedures calibrated this study's results to the global FIES reference scale and computed internationally comparable prevalence rates of both moderate and severe food insecurity. A regression analysis assessed the relationship between household variables and food security. RESULTS: The FIES met benchmarks for fit statistics for all eight items and the overall Rasch reliability is 0.7. As of 2017, Bahamians' prevalence of moderate and severe food insecurity was 21%, and the prevalence of severe food insecurity was 10%. Statistically significant variables that contribute to food insecurity included education, age, gender, and presence of diabetes, high blood pressure, or heart disease. Results also indicated that Bahamians experience food insecurity differently than populations across the globe, likely due in large part to the workings of an isolated food system heavily dependent on foreign imports. Responses showed that by the time a Bahamian worries they will not have enough food to eat, they have already restricted their meals to a few kinds of foods and begun to limit their intake of vegetables and fruits. CONCLUSION: This study, which is among the first to comprehensively measure food security in The Bahamas, provides a baseline for further research and evaluation of practices aimed at mitigating food insecurity in small island developing states. Further, this study provides a benchmark for future research, which may seek to understand the impacts of Hurricane Dorian and COVID-19, disasters further isolating the remote island nation. Post-disaster food security data are needed to further understand the extent to which food security is impacted by natural disasters and identify which sectors and stakeholders are most vital in restructuring the agricultural sector and improving food availability following catastrophic events.

RESUMEN

(1) Background: Despite considerable efforts to increase farmers' market access (FM) and improve household fruit and vegetable (FV) purchasing in low-income communities, little is known about the FV purchasing and consumption characteristics of low-income Hispanic farmers' market shoppers. (2) Methods: A secondary analysis of baseline data from a farmers' market study conducted between 2015 and 2017 (n = 2825) was performed. Participants who also received supplemental nutrition assistance program (SNAP) completed a 31-item online survey assessing demographics, health characteristics, and FV purchasing and consumption habits. Descriptive statistics and bivariate analyses were used to assess between- and within-group differences amongst Hispanic and non-Hispanic households. Regression analyses were used to examine associations among BMI, FV purchasing and consumption, and household size for Hispanic and non-Hispanic households as well as for Hispanic subgroups. (3) Results: The sample included 515 Hispanic and 2310 non-Hispanic SNAP-using FM shoppers in 13 states. Despite experiencing significantly higher food insecurity (89% vs. 81%, non-Hispanic), Hispanic shoppers consumed similar amounts of FV (3.04 cups/day) and spent less doing so. Significant subgroup differences were identified for FV purchasing. (4) Conclusions: Findings emphasize the importance of food insecurity and household size in FV interventions and underscore the capacity of Hispanic families to maintain FV consumption.

RESUMEN

The food retail environment has been directly linked to disparities in dietary behaviors and may in part explain racial and ethnic disparities in pregnancy-related deaths. The Special Supplemental Nutrition Program for Women, Infants and Children (WIC), administered by the United States Department of Agriculture, is associated with improved healthy food and beverage access due to its requirement for minimum stock of healthy foods and beverages in WIC-eligible stores. The selection and authorization criteria used to authorize WIC vendors varies widely from state to state with little known about the specific variations. This paper reviews and summarizes the differences across 16 of these criteria enacted by 89 WIC administrative agencies: the 50 states, the District of Columbia, five US Territories, and 33 Indian Tribal Organizations. Vendor selection and authorization criteria varied across WIC agencies without any consistent pattern. The wide variations in criteria and policies raise questions about the rational for inconsistency. Some of these variations, in combination, may result in reduced access to WIC-approved foods and beverages by WIC participants. For example, minimum square footage and/or number of cash register criteria may limit vendors to larger retail operations that are not typically located in high-risk, under-resourced communities where WIC vendors are most needed. Results highlight an opportunity to convene WIC stakeholders to review variations, their rationale, and implications thereof especially as this process could result in improved policies to ensure and improve healthy food and beverage access by WIC participants. More work remains to better understand the value of state WIC vendor authorization authority, particularly in states that have provided stronger monitoring requirements. This work might also examine if and how streamlining WIC vendor criteria (or at least certain components of them) across regional areas or across the country could provide an opportunity to advance interstate commerce and promote an equitable supply of food across the food system, while ensuring the protection for local, community-oriented WIC vendors.

RESUMEN

BACKGROUND: The generalized propensity score (GPS) addresses selection bias due to observed confounding variables and provides a means to demonstrate causality of continuous treatment doses with propensity score analyses. Estimating the GPS with parametric models obliges researchers to meet improbable conditions such as correct model specification, normal distribution of variables, and large sample sizes. OBJECTIVES: The purpose of this Monte Carlo simulation study is to examine the performance of neural networks as compared to full factorial regression models to estimate GPS in the presence of Gaussian and skewed treatment doses and small to moderate sample sizes. RESEARCH DESIGN: A detailed conceptual introduction of neural networks is provided, as well as an illustration of selection of hyperparameters to estimate GPS. An example from public health and nutrition literature uses residential distance as a treatment variable to illustrate how neural networks can be used in a propensity score analysis to estimate a dose-response function of grocery spending behaviors. RESULTS: We found substantially higher correlations and lower mean squared error values after comparing true GPS with the scores estimated by neural networks. The implication is that more selection bias was removed using GPS estimated with neural networks than using GPS estimated with classical regression. CONCLUSIONS: This study proposes a new methodological procedure, neural networks, to estimate GPS. Neural networks are not sensitive to the assumptions of linear regression and other parametric models and have been shown to be a contender against parametric approaches to estimate propensity scores for continuous treatments.

RESUMEN

The objective of this study was to assess consumers' ability to correctly identify different types of milk in a blind taste test and correlates of plans to purchase lower fat milk. Adults from 8 supermarkets in low-income neighborhoods tasted 3 types of unlabeled lower fat or fat-free milk samples and guessed the type of each sample. Of the 1074 participants, only 7.6% were able to identify all 3 unlabeled samples correctly. Most adults in this study reported consuming higher fat milk and could not correctly identify milk type by taste alone. Blind taste tests may encourage consumers to drink lower fat milk.

RESUMEN

OBJECTIVE: To describe a novel, five-phase approach to collecting qualitative data from hard-to-reach populations using crowdsourcing methods. METHODS: Drawing from experiences across recent studies with type 1 diabetes and congenital heart disease stakeholders, we describe five phases of crowdsourcing methodology, an innovative approach to conducting qualitative research within an online environment, and discuss relevant practical and ethical issues. RESULTS: Phases of crowdsourcing methodology are: (I) Preparing; (II) Forming Crowds; (III) Collecting Crowdsourced Data; (IV) Coding and Analyzing Crowdsourced Data; and (V) Generating and Disseminating Findings. Iterative feedback from stakeholders is obtained in all five phases. Practical and ethical issues include accessing diverse stakeholders, emotional engagement of crowd participants, responsiveness and transparency of crowdsourcing methodology, and limited personal contact with crowd participants. CONCLUSIONS: Crowdsourcing is an innovative, efficient, feasible, and timely approach to engaging hard-to-reach populations in qualitative research.

RESUMEN

The consumption of sugar-sweetened beverages (SSBs) has been linked to obesity, diabetes, and other negative health outcomes among children. In response, many government entities have enacted healthy default beverage policies that require restaurants offering bundled kids' meals-food and drink items combined and sold as a single unit-to include only healthier drinks. Despite growing interest in these policies, little is known about their potential reach, restaurant management perceptions, and possible implementation challenges. This study evaluated restaurant managers' knowledge and support of a policy in Delaware that had passed, but not yet gone into effect. We conducted structured in-person interviews with managers (n = 50) from full-service and quick-service chain and non-chain restaurants (QSRs) using a stratified random sample. Managers were interviewed about the number of bundled meals sold, beverage sales with those meals, and awareness and perceptions of the policy. On average, QSRs sold significantly more bundled kids' meals per week (281) compared to full-service restaurants (111), and managers from chain restaurants reported selling significantly more bundled kids' meals per week (233) compared to non-chain restaurants (91). Managers reported 72.5% of those meals were sold with a healthier beverage (water, milk, or 100% juice), consistent with the forthcoming policy, while 28% were sold with SSBs. Furthermore, although only three managers (6%) reported knowing about the policy, the majority supported it when it was explained. Our findings indicate general support for the intent of the policy, but suggest the need for tailored implementation approaches and additional education for restaurant manager's and staff.
