Evaluating the Association of the Increase in the WIC Cash Value Benefit on the Diversity of MyPlate Fruits and Vegetables Redeemed and Consumed By Children in Low-Income Households.

Background: Fruits and vegetables (FV) are a critical source of nutrients, yet children in the United States are not meeting the Dietary Guidelines for Americans (DGA). The monthly FV cash value benefit (CVB) included in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)'s food package to support child FV intake (FVI) received a substantial increase for economic relief during the COVID-19 pandemic. Objectives: To evaluate how an expansion of the monthly WIC CVB to purchase FV for WIC children ages 1-4 y is associated with diversity in FV redeemed, and how changes in redeemed FV are related to FVI. Methods: Caregivers representing 1463 WIC-participating children recruited from Los Angeles County, California, completed surveys during the CVB augmentation (T1: CVB = $9/mo; T2 = $35/mo; T3 = $24/mo). Redeemed price look-up codes (PLUs), corresponding to a food item, were assigned to its corresponding MyPlate FV group. Multivariable generalized estimating equation regression models assessed changes in amount and diversity of FV redemption across MyPlate groups and associations between changes in FV diversity and changes in FVI. Results: Slightly over half of all households were food insecure (55%), half of the children were female (52%), and most were Hispanic (78%). Compared with T1, significant increases in the number of PLUs and dollars redeemed were observed in most MyPlate FV groups. From T1 to T2, significant increases in diversity scores were observed for total fruit (ß: 1.6 pts; 95% confidence interval [CI]: 1.4, 1.7), total vegetable (ß: 3.6 pts; 95%CI: 3.4, 3.9), and total FV (ß:7.8 pts; 95%CI: 7.4, 8.2). Similarly, increases in diversity score were observed at T3 compared with T1. Changes in FV diversity redeemed were not associated with changes in FVI. Conclusions: During the CVB augmentation, WIC participants redeemed a greater amount and variety of FV according to DGA MyPlate recommendations, supporting its permanent increase.

Understanding Multiprogram Take-Up of Safety Net Programs Among California Families.

Introduction: The U.S. safety net, which provides critical aid to households with low income, is composed of a patchwork of separate programs, and many people with low income benefit from accessing <1 program. However, little is known about multiprogram take-up, that is, participation conditioned on eligibility. This study examined individual and multiprogram take-up patterns and sociodemographic factors associated with multiprogram take-up of U.S. safety net programs. Methods: The Assessing California Communities' Experiences with Safety Net Supports study interviewed Californians and reviewed their 2019 tax forms between August 2020 and May 2021. Take-up of safety net programs was calculated among eligible participants (n=365), including the Earned Income Tax Credit; Supplemental Nutrition Assistance Program; the Special Supplemental Nutrition Program for Women, Infants, and Children; and Medicaid. Multivariable regressions identified sociodemographic factors associated with take-up of multiple programs. Results: Take-up was highest for Medicaid (90.6%) and lowest for Supplemental Nutrition Assistance Program (57.5%). Among people who received benefits from at least 1 other program, take-up ranged from 81.7% to 84.8% for the Earned Income Tax Credit; 54.4%-62.0% for Supplemental Nutrition Assistance Program; 74.3%-80.1% for Special Supplemental Nutrition Program for Women, Infants, and Children; and 89.7%-98.1% for Medicaid. Having a lower income and being younger were associated with concurrent take-up of Supplemental Nutrition Assistance Program and Special Supplemental Nutrition Program for Women, Infants, and Children. Among Supplemental Nutrition Assistance Program and Special Supplemental Nutrition Program for Women, Infants, and Children recipients, having higher income, being older, and being primarily English speaking were associated with Earned Income Tax Credit take-up. Conclusions: Individual and multiprogram take-up vary between programs and by sociodemographic factors. Findings suggest opportunities to increase take-up of potentially synergistic programs by improving cross-program coordination, data sharing, and targeted recruitment of underenrolled subgroups (Supplemental Nutrition Assistance Program and Special Supplemental Nutrition Program for Women, Infants, and Children).

Food, nutrition, and autism: from soil to fork.

Food and nutrition-related factors have the potential to impact development of autism spectrum disorder (ASD) and quality of life for people with ASD, but gaps in evidence exist. On 10 November 2022, Tufts University's Friedman School of Nutrition Science and Policy and Food and Nutrition Innovation Institute hosted a 1-d meeting to explore the evidence and evidence gaps regarding the relationships of food and nutrition with ASD. This meeting report summarizes the presentations and deliberations from the meeting. Topics addressed included prenatal and child dietary intake, the microbiome, obesity, food-related environmental exposures, mechanisms and biological processes linking these factors and ASD, food-related social factors, and data sources for future research. Presentations highlighted evidence for protective associations with prenatal folic acid supplementation and ASD development, increases in risk of ASD with maternal gestational obesity, and the potential for exposure to environmental contaminants in foods and food packaging to influence ASD development. The importance of the maternal and child microbiome in ASD development or ASD-related behaviors in the child was reviewed, as was the role of discrimination in leading to disparities in environmental exposures and psychosocial factors that may influence ASD. The role of child diet and high prevalence of food selectivity in children with ASD and its association with adverse outcomes were also discussed. Priority evidence gaps identified by participants include further clarifying ASD development, including biomarkers and key mechanisms; interactions among psychosocial, social, and biological determinants; interventions addressing diet, supplementation, and the microbiome to prevent and improve quality of life for people with ASD; and mechanisms of action of diet-related factors associated with ASD. Participants developed research proposals to address the priority evidence gaps. The workshop findings serve as a foundation for future prioritization of scientific research to address evidence gaps related to food, nutrition, and ASD.

Sleep Duration Is Associated with Household Food Insecurity and Sugar-Sweetened Beverage Intake Among Women, Infants and Children Participating Children Ages 0-5.

PURPOSE: To determine associations between child and household characteristics and sleep duration among low-income children in Los Angeles County. DESIGN: Cross-sectional study. SETTING: Survey data collected in 2017 and 2020 in Los Angeles County, California. SAMPLE: Special Supplemental Nutrition Program for Women, Infants and Children (WIC) households with children ages 4-60 months. MEASURES: Sleep duration for children 4-60 months old (less than recommended (LTR), recommended range, more than recommended (MTR)), household food insecurity (HFI), sociodemographics, and daily servings of sugar-sweetened beverages (SSB). ANALYSIS: Multinomial logistic regression, stratified by child age, was used to calculate odds ratios (OR) and 95% confidence intervals (CI) for associations between household/child characteristics and LTR or MTR sleep compared to recommended duration among WIC participating children 4-60 months old. RESULTS: The final sample included 3512 children ages 4-23 months and 6035 children ages 24-60 months. In the study population, 32% (3-5 years old) to 44% (4-11months) of children under 5 did not meet the recommended hours of sleep per night. HFI was associated with higher odds of LTR (OR 1.27, CI 1.12-1.45) and MTR (OR 1.46, CI 1.15-1.87) sleep among 24-60 month-old children. Each additional daily SSB serving was associated with higher odds of LTR sleep (4-23 months: OR 1.10, CI 1.02-1.19; 24-59 months: OR 1.12, CI 1.08-1.17). CONCLUSIONS: HFI and SSB intake are associated with not getting the recommended amount of sleep among low-income WIC participating children. Nutrition assistance program participants may benefit from receiving information about recommended sleep duration for young children and how to establish sleep routines to optimize sleep duration.

"What Matters to You?": A Participant-Centered Approach to Needs Identification and Referral to Community Resources.

OBJECTIVE: Referral to social and health services is a core process of the Special Supplemental Nutrition Program for Women, Infants and Children (WIC). We evaluate the feasibility and acceptability of a referral innovation implemented at two New York City WIC sites. This program aimed to improve retention by increasing WIC's perceived value by addressing unmet needs of WIC families. The two main components were needs assessment via conversation and a closed-loop referral process for WIC families with children aged 6-9 months and 18-21 months. DESIGN: Referral outcomes from Unite Us and program data were tracked and assessed using descriptive univariate analyses. We conducted 29 in-depth interviews with caregivers and six focus groups with WIC and CBO staff. Qualitative data were analyzed using thematic framework analysis. RESULTS: From February 2020 through January 2021, 1,675 WIC caregivers participated in a conversation about their family's needs. Four hundred sixty-one caregivers were referred to at least one service. 95 received services or benefits. In interviews, caregivers viewed referrals to other services positively but were not aware WIC could address needs holistically. In focus groups, WIC staff liked the conversation script but highlighted barriers to making referrals. CBO partners valued network participation as it increased their reach to new families. CONCLUSIONS AND IMPLICATIONS: Our approach facilitated targeted referrals for WIC participants. It is an acceptable enhancement of the WIC referral process with potential to strengthen WIC as a community provider.

Consequences of the 2019 Public Charge Rule Announcement and Publication on Prenatal WIC Participation Among Immigrant Families: Evidence of Spillover Effects.

This study analyzed the effects of the announcement and publication of the 2019 Public Charge Rule on participation of the special supplemental nutrition program for women, infants, and children (WIC) among pregnant immigrants. A difference-in-differences approach was used to analyze the changes in prenatal WIC participation before and after the 2019 Public Charge Rule announcement and publication among immigrants relative to US natives. We identified 17,623,683 live singletons born in a hospital from 2015 to 2019. Compared to US natives, the odds of prenatal WIC participation among immigrants were 11.4% lower after the 2019 Public Charge Rule announcement, and 19% lower after the final rule was published. The results of this study suggest that pregnant immigrants may decide not to participate in the WIC program due to the fear of jeopardizing their immigration status after the announcement and publication of the 2019 Public Charge Rule.

Pantry clients and Supplemental Nutrition Assistance Program-Education practitioners' perspectives on factors influencing healthy eating policy, system and environmental interventions in food pantries.

The Supplemental Nutrition Assistance Program-Education identified food pantries as a targeted setting for policy, system, and environmental (PSE) interventions to promote healthy eating among households who rely on pantries to supplement their food needs. The present study sought to identify factors influencing capacity and readiness to implement healthy eating PSE interventions in food pantries. Qualitative interviews were conducted via zoom with twenty-six community residents with experience receiving SNAP benefits and twelve SNAP-Ed staff in rural and urban counties in Ohio to identify themes and indicators related to community/organisational capacity and readiness to implement healthy eating PSE interventions in food pantries. Themes and related indicators generated based on inductive and deductive coding of interview transcripts were prioritised and weighted by eleven community nutrition experts during a virtual consensus conference. Five themes emerged; expert-derived weights (scaled low, 0 to high, 1) reflect the perceived importance of each to implementation of healthy eating PSE interventions in food pantries: food pantry capacity and logistics [0⋅252], networks and relationships [0⋅228], community nutrition practitioner capacity [0⋅212], food pantry user characteristics [0⋅156], and stigma and stereotypes [0⋅1⋅52]. Overall, seventeen indicators were identified reflecting these themes. Successful and sustained PSE interventions at food pantries will require a tailored approach that considers food pantries' capacity, needs and opportunities within the community, and capacity of community nutrition practitioners. The themes and indicators identified provide guidance for responsive PSE approaches in food pantries that meet communities where they are.

The association between statistical learning and language development during childhood: A scoping review.

The statistical account of language acquisition asserts that language is learned through computations on the statistical regularities present in natural languages. This type of account can predict variability in language development measures as arising from individual differences in extracting this statistical information. Given that statistical learning has been attested across different domains and modalities, a central question is which modality is more tightly yoked with language skills. The results of a scoping review, which aimed for the first time at identifying the evidence of the association between statistical learning skills and language outcomes in typically developing infants and children, provide preliminary support for the statistical learning account of language acquisition, mostly in the domain of lexical outcomes, indicating that typically developing infants and children with stronger auditory and audio-visual statistical learning skills perform better on lexical competence tasks. The results also suggest that the relevance of statistical learning skills for language development is dependent on sensory modality.

Federal Food Program Participation and Beverage Intake Among Families With Low Household Income.

OBJECTIVE: Examine beverage intake among families with low income by household participation in federal food assistance programs. DESIGN: Cross-sectional study conducted in fall/winter 2020 via an online survey. PARTICIPANTS: Mothers of young children insured by Medicaid at the time of the child's birth (N = 493). VARIABLES MEASURED: Mothers reported household federal food assistance program participation, later categorized as Supplementation Nutrition Program for Women, Infants, and Children (WIC) only, Supplemental Nutrition Assistance Program-Education (SNAP) only, both WIC and SNAP, and neither. Mothers reported beverage intake for themselves and their children aged 1-4 years. ANALYSIS: Negative binomial and ordinal logistic regression. RESULTS: After accounting for sociodemographic differences between groups, mothers from households participating in WIC and SNAP consumed sugar-sweetened beverages (incidence rate ratio, 1.63; 95% confidence interval [CI], 1.14-2.30; P = 0.007) and bottled water (odds ratio, 1.76; 95% CI, 1.05-2.96; P = 0.03) more frequently than mothers from households in neither program. Children from households participating in WIC and SNAP also consumed soda (incidence rate ratio, 6.07; 95% CI, 1.80-20.45; P = 0.004) more frequently than children in either program. Few differences in intake were observed for mothers or children participating in only WIC or SNAP vs both programs or neither program. CONCLUSION AND IMPLICATIONS: Households participating in both WIC and SNAP may benefit from additional policy and programmatic interventions to limit sugar-sweetened beverage intake and reduce spending on bottled water.

Application Status Among Women Enrolled in a Healthy Start Program in Arkansas for the Special Nutrition Program for Women and Children.

This study aimed to examine the demographic characteristics of pregnant women in a Healthy Start program who are presumed eligible for the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), but who have not yet applied for WIC benefits. We used a cross sectional evaluation of data collected from pregnant women (n=203) participating in a Healthy Start program. Data came from surveys administered at enrollment in the Healthy Start program from July 15th, 2019 until January 14th, 2022. The primary outcome was WIC application status, which was determined by whether the woman had applied or was receiving benefits at the time of enrollment. Covariates included race/ethnicity, marital status, insurance, education, income, age, employment, and having previous children/pregnancies. Fisher exact tests and logistic regression were used to examine associations. Approximately 65% of women had not yet applied for WIC benefits. Marshallese women (80.9%) and other NHPI women (80.0%) had the highest need for assistance. In adjusted analyses, White women (p = 0.040) and Hispanic women (p = 0.005) had lower rates of needing assistance applying for WIC than Marshallese women. There were higher rates of needing assistance in applying for women with private insurance or with no insurance and for those with higher incomes. Nearly two out of every three pregnant women who were eligible for WIC had not yet applied for benefits. The findings highlight the need for outreach for all populations that may be eligible, particularly among racial/ethnic minorities and those with higher incomes.

COVID-19 Response Resource Engagement and User Characteristics of the Wichealth Web-Based Nutrition Education System: Comparative Cross-sectional Study.

BACKGROUND: In response to the COVID-19 pandemic, Wichealth launched 4 information resources on the site's user landing dashboard page. These resources were used consistently during the period in which they were available (April 1, 2020, through October 31, 2021); however, only 9% (n=50,888) of Wichealth users eligible for inclusion in the study accessed at least one resource. User engagement with emergency response resources within the context of a web-based health educational tool has not been well investigated due to a paucity of opportunities and a lack of the ability to evaluate relevant users at scale. OBJECTIVE: This investigation was carried out to understand if user characteristics and behaviors measured by the Wichealth web-based education system are associated with a participant's motivation, or lack thereof, to engage with the added COVID-19 resources. METHODS: Sociodemographic characteristics were gathered from Wichealth users with at least one lesson completed and a complete user profile to identify which factors increase the likelihood of user access of any of the Wichealth COVID-19 response resources during the 19-month period between April 1, 2020, and October 31, 2021. A logistic regression analysis was conducted to determine the relative importance of all factors on the likelihood of a user accessing the COVID-19 resources. RESULTS: A total of 50,888 unique Wichealth users included in the study accessed the COVID-19 response resources 66,849 times during the time period. During the same period, 510,939 unique Wichealth users completed at least one lesson about how to engage in healthy behaviors with respect to parent-child feeding but did not access any COVID-19 resources. Therefore, only 9% of Wichealth users who completed a lesson during the time when COVID-19 response resources were available accessed any of the information in those resources. Users of the Spanish language Wichealth version, older users, those less educated, and users with prior Wichealth lesson engagement demonstrated the greatest likelihood of COVID-19 resource use. CONCLUSIONS: This investigation presents findings that demonstrate significant differences between Wichealth users that opted to access COVID-19-specific resources and those who chose not to during their web-based educational session. Reaching users of a web-based educational system with supplemental information may require multiple strategies to increase coverage and ensure the widest possible distribution.

Relationship between short stature at 3 years old and height, weight, and body mass index changes for 6 years after birth: a retrospective, nationwide, population-based study of children born 2011-2014 in Korea.

PURPOSE: Height at 3 years of age, when catch-up growth based on birth history is completed, is considered a major prognostic factor for predicting short stature, underweight, and growth faltering. However, too few large-scale studies have followed and analyzed height, weight, and body mass index (BMI) changes in children whose stature was short at 3 years of age. This study followed and compared the growth parameters (height, weight, and BMI) of children with short stature at 3 years of age and children with nonshort stature at 3 years of age for 6 years after birth using nationwide, population-based data. METHODS: We retrospectively analyzed physical measurement data from the National Health Screening Program for Infants and Children for people born in 2011-2014 in Korea and followed to 2020. The data were provided by the National Health Insurance Service's customized data service. Growth parameters were compared using chi-square tests, Student t-tests, analyses of variance, and linear regressions. RESULTS: Among 210,902 enrolled participants, 759 (0.4%) and 210,143 (99.6%) were in the short stature at 3 years group and the nonshort stature at 3 years group, respectively. In both sexes, height, weight, and BMI for 6 years after birth were significantly higher in the nonshort stature at 3 years group than in the short stature at 3 years group (P<0.0001). The BMI rebound was observed later than the standard period in the short stature at 3 years group. CONCLUSION: Early intervention and close follow-up are necessary to prevent persistent short stature and growth faltering in children with short stature at 3 years of age.

A Quasi-Experimental Assessment of the Effect of the 2009 WIC Food Package Revisions on Breastfeeding Outcomes.

Breastfeeding rates among infants participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) are consistently lower than those of WIC nonparticipants. The 2009 WIC food package revisions were intended to incentivize breastfeeding among the WIC population. To examine the effectiveness of this policy change, we estimated an intent-to-treat regression-adjusted difference-in-difference model with propensity score weighting, an approach that allowed us to control for both secular trends in breastfeeding and selection bias. We used novel data from the Feeding Infants and Toddlers Survey from 2008 and 2016. We defined our treatment group as infants eligible for WIC based on household income and our control group as infants in households with incomes just above the WIC eligibility threshold. The breastfeeding outcomes we analyzed were whether the infants were ever breastfed, breastfed through 6 months, and breastfed exclusively through 6 months. We observed significant increases in infants that were ever breastfed in both the treatment group (10 percentage points; p < 0.01) and the control group (15 percentage points; p < 0.05); however, we did not find evidence that the difference between the two groups was statistically significant, suggesting that the 2009 revisions may not have had an effect on any of these breastfeeding outcomes.

Prevalence and Predictors of Substantial Postpartum Weight Retention Among Participants of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Southern California.

PURPOSE: Identify the prevalence and predictors of substantial postpartum weight retention (SPPWR) among WIC mothers in Southern California during their first postpartum year. DESIGN: Secondary data analysis. SETTING: The 2020 Los Angeles County WIC Survey. SUBJECTS: Mothers of children up to 1-year-old (N = 1019). MEASURES: Outcome variable: SPPWR (≥5 kg above pre-pregnancy weight). Predictors: child's age, mother's age, race, education, employment status since having child, healthcare coverage, food insecurity, depressed mood, instrumental support, emotional support, spouse's participation in child's life, gestational weight gain (GWG), pre-pregnancy BMI, any breastfeeding, and gestational diabetes. ANALYSIS: Weighted descriptive statistics and binary logistic regression. RESULTS: The prevalence of SPPWR was 31%. We found that for every 1 month increase in the child's age (proxy for postpartum duration), the likelihood of SPPWR increased by 9% (AOR = 1.09, CI = 1.04-1.15). Mothers were more likely to have SPPWR when they exceeded GWG guidelines (AOR = 3.43, CI = 2.46-4.79). Compared to mothers with normal pre-pregnancy BMIs, mothers with overweight (AOR = .64, CI = .44-.94) and obese (AOR = .39, CI = .26-.58) pre-pregnancy BMIs were less likely to experience SPPWR. CONCLUSION: Postpartum duration and maternal anthropometric characteristics were associated with SPPWR during the first postpartum year. Extending WIC eligibility for postpartum mothers to 2 years through the Wise Investment in Children Act may give WIC providers the opportunity to work closely with Southern California WIC mothers to achieve a healthy weight after pregnancy.

From childhood obesity risk to healthy growth in the U.S.: A 10-year social work research & policy update.

Childhood obesity is a major health issue and a prominent chronic health condition for children in the United States (U.S.), caused by a multitude of factors. Most existing models of childhood obesity prevention have not worked, yielding little to no effect on improving weight status or the proximal health behaviors most attributed to obesity risk: nutritional intake, physical activity, sedentary behaviors, and sleep. There is an urgent need for new approaches to prevent health disparities that are responsive to impacts of economic inequality on healthy child growth in marginalized populations. In this Short Commentary, a social justice update is provided to motivate a new generation of research that promotes equitable and healthy child growth under present-day social, economic, and political circumstances. Social work-specific research and policy recommendations are provided to guide future research that targets underlying social and economic determinants of weight-related health disparities in childhood. Recommendations include research on cross-disciplinary metrics to better capture reductions in health disparities and the development and testing of policy and system interventions that address structural issues and strengthen health resources in marginalized communities. Progress in reducing disparities in childhood obesity will likely remain inhibited until recommendations from social work research are incorporated to strengthen existing medical and public health models and redirect the childhood obesity epidemic toward equitable, healthy child growth.

Computed Analysis of Retinal Vascular Growth After Bevacizumab Treatment of Retinopathy of Prematurity Until Age 3 Years.

PURPOSE: Premature infants, after anti-vascular endothelial growth factor injections for retinopathy of prematurity, have persistent peripheral avascular retina (PAR). PAR is ablated with laser; however, physiologic growth of the retinal vasculature in the long term has not been measured. The purposes of this study were to measure retinal vessel growth after treatment with intravitreal bevacizumab (IVB) for retinopathy of prematurity, using serial fluorescein angiography (FA), until age 3 years, and to assess the timing for providing laser ablation in PAR. METHODS: Data from an observational, longitudinal clinical study were collected. Angiographic images of eyes treated with IVB were included; imaging data from laser photocoagulation were excluded. All eyes underwent initial examination under general anesthesia with FA and photographic imaging. The retinal vessel length was measured from the temporal margin of the optic disc passing through the foveal center, and the lengths at subsequent FA were compared. To compare the changes in retinal vessel length over time in individual eyes, a paired-sample t test was performed. FINDINGS: FA images from 70 eyes (35 infants) treated with IVB were available. A total of 150 FA images were available for review; data from 125 images of good quality were used for analysis. The mean postmenstrual ages (PMAs) at first, second, third, and fourth FA were 66.2, 100.9, 135.1, and 180.7 weeks, respectively. The mean retinal vessel length was 14.177 mm at first FA and 13.199 mm at fourth FA (PMA range, 42...234 weeks). Retinal vascular lengths of individual eyes compared over time showed no statistically significant growth from the first FA to age 3 years. The changes in retinal vessel length from first to second FA were -0.117 ± 0.79 mm (p = 0.42; n = 30); from first to third FA, +0.060 ± 0.85 mm (p = 0.79; n = 15); and first to fourth FA, -0.404 ± 1.32 mm (p = 0.45; n = 7). IMPLICATIONS: Beyond 65 weeks' PMA, no meaningful retinal vascular growth occurred after IVB up to age 3 years, guiding the timing for physicians if laser photocoagulation is being considered. Future studies are needed to address retinal growth changes in the growing eyes of infants.

Breastfeeding Outcomes Associated With the Special Supplemental Nutrition Program for Women, Infants, and Children: A Systematic Review.

BACKGROUND: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) promotes and supports breastfeeding for low-income women and children. A prior review reported negative associations of WIC with breastfeeding outcomes. WIC food package changes in 2009 increased breastfeeding support. OBJECTIVE: The objectives of this systematic review were to 1) evaluate evidence on WIC participation and breastfeeding outcomes and 2) evaluate breastfeeding outcomes of WIC participants before versus after the 2009 food package. DATA SOURCES: PubMed, Embase®, CINAHL, ERIC, SCOPUS, PsycINFO, and the Cochrane Central Register of Controlled Trials for papers published January 2009 to April 2022. ELIGIBILITY CRITERIA: Included studies compared breastfeeding outcomes (initiation, duration, exclusivity, early introduction of solid foods) of WIC participants with WIC-eligible nonparticipants, or among WIC participants before versus after the 2009 package change. STUDY APPRAISAL METHODS: Two independent reviewers evaluated each study and assessed risk of bias using EHPHP assessment. RESULTS: From 13 observational studies we found: 1) moderate strength of evidence (SOE) of no difference in initiation associated with WIC participation; 2) insufficient evidence regarding WIC participation and breastfeeding duration or exclusivity; 3) low SOE that the 2009 food package change is associated with greater breastfeeding exclusivity; 4) low SOE that WIC breastfeeding support services are positively associated with initiation and duration. LIMITATIONS: Only observational studies, with substantial risk of bias and heterogeneity in outcomes and exposures. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: WIC participation is not associated with a difference in breastfeeding initiation compared to WIC-eligible nonparticipants, but the 2009 food package change may have improved breastfeeding exclusivity among WIC participants and receipt of breastfeeding support services may have improved breastfeeding initiation and duration.

Coordination Between Primary Care and Women, Infants, and Children to Prevent Obesity for Infants from Low-Income Families: A Pragmatic Randomized Clinical Trial.

Background: Rapid weight gain during infancy is associated with risk for later obesity, yet little research to date has examined the effect of a responsive parenting (RP) intervention with care coordination between pediatric primary care providers and Women, Infants, and Children nutritionists on infant weight. Methods: The Women, Infants, and Children Enhancements to Early Healthy Lifestyles for Baby (WEE Baby) Care study is a pragmatic, randomized clinical trial for mothers and infants (n = 288) designed to examine the effect of a patient-centered RP intervention that used advanced health information technology strategies to coordinate care to reduce rapid infant weight gain compared with standard care. General linear models examined intervention effects on infant conditional weight gain scores, weight-for-age z scores, BMI, and overweight status (BMI-for-age ≥85th percentile) from birth to age 6 months, and mothers' use of food to soothe from age 2 to 6 months. Results: There were no intervention effects on infant conditional weight gain scores or overweight status at 6 months. Infants in the RP intervention had lower mean weight-for-age z scores [M = -0.04, standard error (SE) = 0.04 vs. M = 0.05, SE = 0.04; p = 0.008] and lower mean BMI (M = 16.05, SE = 0.09 vs. M = 16.24, SE = 0.09; p = 0.03) compared with standard care. Mothers' use of emotion-based food to soothe was lower in the RP intervention compared with standard care from age 2 to 6 months [M difference = -0.32, standard deviation (SD) = 0.81 vs. 0.00, SD = 0.90; p = 0.01]. Conclusions: This pragmatic, patient-centered RP intervention did not reduce rapid infant weight gain or overweight but was associated with modestly lower infant BMI and reduced mothers' use of emotion-based food to soothe. Trial Registration: clinicaltrials.gov identifier: NCT03482908.

Caregivers' Perceived Impact of WIC's Temporary Cash-Value Benefit (CVB) Increases on Fruit and Vegetable Purchasing, Consumption, and Access in Massachusetts.

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.
