WIC is a critical source of nutrition support for young children in low-income families, providing access to healthy foods and a cash value benefit (CVB) for the purchase of fruits and vegetables (FV). In 2021, the WIC CVB increased substantially for women and children ages 1 to 5. To investigate whether the increased WIC Cash Value Benefit (CVB) for purchasing fruits and vegetables (FV) was associated with greater redemption of the FV benefit, satisfaction, household food security (HFS), and child FV intake. Longitudinal study of WIC participants receiving WIC benefits from May 2021 through May 2022. Through May 2021, the WIC CVB for children ages 1-4 was $9/month. The value increased to $35/month from June-September 2021, and changed to $24/month starting October 2021. WIC participants from 7 WIC sites in California with ≥1 child ages 1-4 years in May 2021 and ≥1 follow-up survey in September 2021 or May 2022 (n=1,770). CVB redemption (USD), satisfaction with the amount (prevalence), HFS (prevalence), and child FV intake (cups/day). Associations (95% confidence interval) of increased CVB issuance following the June 2021 CVB augmentation with child FV intake and CVB redemption were assessed using mixed effects regression, and associations with satisfaction and HFS were assessed using modified Poisson regression. The increased CVB was associated with significantly greater redemption and satisfaction. At the second follow-up (May 2022), HFS increased by 10% (7%,12%); total FV intake decreased by 0.03 cups/day (-0.06,-0.01) in the overall sample, but increased by 0.23 cups/day (0.17,0.29) among children with the lowest baseline FV intake. This study documented benefits of augmentation to the CVB for children. WIC policy augmenting the value of WIC food packages to increase access to FV had the intended effects, lending support to making the increased FV benefit permanent.

Many Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinics implemented alternatives to in-person service delivery in response to the COVID-19 pandemic, including virtual visits and electronic document sharing. The objective of this cross-sectional study was to describe WIC participants’ experiences with remote service delivery and recertification during the pandemic. Participants included mothers and infants who participated in a WIC-based intervention between June 2019-August 2020. All participants (N = 246) were invited to complete a follow-up survey between November 2020-February 2021; 185 mothers completed the survey. The survey assessed sociodemographics, employment, food security, experiences with remote WIC recertification and service delivery, and experiences with obtaining WIC foods during the pandemic. Average age for mothers was 29.2 ± 6.3 years and for infants was 17.7 ± .2 months; 80% (n = 147) identified as Hispanic. Approximately 34% (n = 62) of participants reported very low or low food security and 40% (n = 64) had difficulties buying WIC foods during the pandemic. Among participants who recalled providing documentation of income and address virtually, the majority felt comfortable providing information via email (60%) and text messaging (72%). Participants reported high levels of satisfaction with remote methods of service delivery, as well as overall satisfaction with the WIC program during the pandemic. While ~ 25% of study participants preferred for all WIC services to remain remote, 75% still desired at least some in-person contact with WIC staff after the pandemic. In conclusion, remote methods of WIC service delivery addressed existing barriers to WIC participation and were well-received by study participants.

The United States Department of Agriculture approved an increase to the Cash Value Benefit (CVB) for the purchase of fruits and vegetables issued to participants receiving an eligible Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food package. In order to understand satisfaction, perceptions, and the overall impact of additional benefits for fruits and vegetables at the household level, a qualitative study consisting of structured phone interviews was conducted with families served by WIC in Southern California from November to December 2021 (n = 30). Families were selected from a large longitudinal study sample (N = 2784); the sample was restricted by benefit redemption and stratified by language and race. WIC participants were highly satisfied with the CVB increase, reporting increased purchasing and consumption of a variety of fruits and vegetables. Respondents noted the improved quality and variety of fruits and vegetables purchased due to the increased amount. Findings are expected to inform policy makers to adjust the CVB offered in the WIC food package with the potential to improve participant satisfaction and increase participation and retention of eligible families with benefits from healthy diets supported by WIC.

Bottle-fed infants are at greater risk for overfeeding and rapid weight gain (RWG); evidence-based strategies for promoting healthy bottle-feeding practices are needed. Our aim was to assess whether policy, systems, and environmental (PSE) strategies for promoting responsive bottle-feeding practices within the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) were associated with lower risk for RWG. We conducted a matched-pair cluster randomized trial. PSE strategies were implemented at 3 WIC clinics in Los Angeles County. PSE clinics were compared with 3 matched control clinics. Mothers and infants were assessed when infants were newborn and 3 months and 6 months of age. Participants were mothers (n = 246) who enrolled their newborn infants (younger than 60 days) into WIC between May and August 2019. Infant weight was assessed and standardized to sex- and age-specific z scores. RWG was defined as weight-for-age z score change > 0.67. Mothers completed questionnaires assessing responsive and pressuring feeding styles, breast- and bottle-feeding patterns, and perceptions of WIC experiences. Logistic regression with estimation via generalized estimating equations and linear mixed models with repeated measures assessed effects of PSE strategies on categorical and continuous outcomes, respectively. Infants in PSE clinics had significantly lower likelihood of exhibiting RWG (P = .014) than infants in control clinics. Mothers in PSE and control clinics reported similar levels of responsive and pressuring feeding style and similar prevalence of breastfeeding and bottle-feeding. Mothers in PSE clinics trended toward feeling better supported with respect to their decision to bottle-feed (P = .098) and had more stable intentions to stay in the WIC program (P = .002) compared with mothers in control clinics. PSE strategies focused on promoting more inclusive assessment of infant feeding, tailored bottle-feeding counseling, and increased education and support for responsive bottle-feeding were associated with lower risk for RWG among WIC infants.
