"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.

Trends in Food Consumption Among Children Aged 1-4 Years by Participation in the Special Supplemental Nutrition Program for Women, Infants, and Children, United States, 2005-2018.

BACKGROUND: In 2009, the US Department of Agriculture Food and Nutrition Service's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food packages were revised to include more whole fruits, vegetables, whole grains, and lower-fat milk. OBJECTIVE: The aim of this study was to describe trends over time in the consumption of fruits (total and whole), vegetables, whole grains, milk (whole, reduced fat, low-fat or nonfat (LFNF), and flavored), and added sugars, including breakfast cereals, by WIC participation status (current WIC recipient, WIC income-eligible nonrecipient, and WIC income-ineligible nonrecipient). METHODS: Dietary intakes on a given day for 1- to 4-y-old children (n = 5568) from the 2005-2018 National Health and Nutrition Examination Survey (NHANES) were analyzed to examine trends in the percentage of individuals consuming and amounts consumed over time using linear regression adjusted for age, sex, and race and Hispanic origin. RESULTS: From 2005 through 2018, the percentage of WIC recipients or WIC income-eligible nonrecipients consuming fruits and vegetables on a given day did not change, but the percentage of fruit consumed as whole fruit increased significantly among WIC recipients (36.4%-62.1%), but not among income-eligible nonrecipients. Among the WIC recipients, the percentage of consumption (5.5%-29.3%), the amount of LFNF milk servings consumed (0.1-0.4 cups), and the percentage of the total milk consumed as LFNF milk (4.8%-27%) significantly increased from 2005 to 2018. Conversely, the percentage of energy (12.3%-10.8%) and servings (11.4-10.6 teaspoons) from added sugars declined significantly. Among WIC-eligible nonrecipients, the servings of whole grains increased significantly, whereas servings and percentage of energy from added sugars declined significantly. CONCLUSIONS: From 2005 through 2018, changes in dietary patterns for WIC recipients did not always mirror those of US children of the same age. The percentage of fruit consumed as whole fruit, and the percentage and quantity of milk consumed as LFNF milk increased significantly among WIC recipients, but not among income-eligible nonrecipients.

The Infant Diet Quality Index Predicts Dietary and Adiposity Outcomes in US Children 2 to 4 years old.

BACKGROUND: Healthy nutrition during the first year of life is critical for optimal growth and development. Limited techniques are available to assess diet quality in infancy, and few have been shown to be predictive of dietary and adiposity outcomes in low-income children. OBJECTIVE: The objectives of this study were to construct an Infant Diet Quality Index (IDQI) to assess the diet quality from birth to 12 mo and to determine whether the IDQI exhibits predictive validity by estimating the longitudinal associations of IDQI scores with diet quality and weight status at 2 to 4 y. DESIGN: Data were analyzed from the longitudinal Women, Infants, and Children Infant and Toddler Feeding Practices Study-2 (unweighted, n = 2858; weighted. N = 392,439) using one 24-h dietary recall and survey responses during infancy. The newly constructed IDQI consists of 16 equally-weighted components: 1) breastfeeding duration; 2) exclusive breastfeeding; age of first introduction of: 3) solids, 4) iron-rich cereals, 5) cow milk, 6) sugar-sweetened beverages, 7) salty/sweet snacks, 8) other drinks/liquids, and 9) textured foods; frequency of consuming 10) fruit or 11) vegetables; frequency of consuming different 12) fruit or 13) vegetables; 14) nonrecommended bottle-feeding practices; 15) use of commercial baby foods; and 16) number of meals and snacks. Regression analysis was used to estimate associations between the total IDQI score (range, 0-1) and Healthy Eating Index-2015 (HEI-2015) scores and body mass index z-scores (BMIz) at 2 to 4 y of age, adjusted for covariates (e.g., child age, sex and race/ethnicity; maternal education level, etc.) RESULTS: The total IDQI score was positively associated with HEI-2015 at the age of 2 y (ß = 16.7; 95% CI: 12.6, 20.9; P < 0.001), 3 y (ß = 14.5; 95% CI: 8.1, 21.0; P < 0.001), and 4 y (ß = 15.4; 95% CI: 8.4, 22.4; P < 0.001); and negatively associated with BMIz at the age of 2 y (ß = -1.24; 95% CI: -2.01, -0.47; P = 0.002) and 4 y (ß = -0.92; 95% CI: -1.53, -0.30; P = 0.003). CONCLUSIONS: The IDQI has predictive validity for diet quality and weight status in low-income US children.

The Special Supplemental Nutrition Program for Women, Infants, and Children food package revisions and anemia in children aged 2-5 years.

BACKGROUND: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides nutritional assistance to low-income women and children in the United States. The WIC food package was revised to align more closely to dietary recommendations in October 2009. The revised package included more fruits, vegetables, whole grains, and low-fat milk. OBJECTIVES: The objective of this study was to examine the association of the revised WIC package with anemia indicators and iron intake in children. METHODS: A quasi-experimental difference-in-difference design compared anemia and iron intake variables between WIC (n = 1497 and n = 1626 for anemia and iron intake variables, respectively) and WIC-eligible nonparticipating children (n = 1183 and n = 1322 for anemia and iron intake variables, respectively), aged 2-5 y, before and after the 2009 revisions. The NHANES 2003-2008 and 2011-2018 data represented the period pre- and post-2009 revisions, respectively. RESULTS: The 2009 package revisions were significantly associated with reduced probability of anemia (-4.3% points; 95% CI: -7.5, -1.1% points) and nonthalassemic microcytic anemia (-1.7% points; 95% CI: -3.3, -0.1% points) in children from WIC-participating households. The revised WIC package also was significantly related to higher nutrient adequacy ratio (0.04; 95% CI: 0.02, 0.07) and greater probability of meeting the RDA (12.1% points; 95% CI: 3.2, 21.0% points) for iron among WIC participants. CONCLUSIONS: This study found that the WIC 2009 revisions were associated with lower probability of nonthalassemic microcytic anemia and better adequacy of dietary iron intake, thereby suggesting the beneficial impact of WIC revisions on iron deficiency anemia in children. The current study findings suggest that nutritional policies could play a crucial role in supporting the health of vulnerable children in the United States.

Additional Fruit and Vegetable Vouchers for Pregnant WIC Clients: An Equity-Focused Strategy to Improve Food Security and Diet Quality.

Women with low household income and from racial/ethnic minority groups are at elevated risk of food insecurity. Food insecurity during pregnancy is associated with overall less healthy diets, lower intake of the pregnancy-supportive nutrients iron and folate, and significant variations in diet across the course of a month. The goal of this study was to explore the impact of an ongoing $40/month supplement for fruits and vegetables (F&Vs) provided to pregnant people enrolled in the Special Supplemental Nutrition Program for Women and Children (WIC). Our primary outcome was food insecurity using the USDA 6-item survey, and our secondary outcome was dietary intake of F&Vs based on the 10-item Dietary Screener Questionnaire. Participants in intervention and comparison counties completed surveys at enrollment and approximately three months later (n = 609). Mean ± SD food insecurity at baseline was 3.67 ± 2.79 and 3.47 ± 2.73 in the intervention and comparison groups, respectively, and the adjusted between-group change from baseline to follow-up in food insecurity was 0.05 [95% CI: −0.35, 0.44] (p > 0.05). F&V intake (in cup equivalents) was 2.56 ± 0.95 and 2.51 ± 0.89 at baseline in the two groups, and the adjusted mean between-group difference in changes from baseline was −0.06 [−0.23, 0.11] (p > 0.05). Recruitment and data collection for this study coincided with the most intensive of America's COVID relief efforts. Our results may indicate that small increases in highly targeted food resources make less of a difference in the context of larger, more general resources being provided to individuals and households in need.

Duration of WIC Participation and Early Feeding Practices Are Associated With Meeting the Added Sugars Recommendation at Age 3 Years.

OBJECTIVE: To examine whether duration of participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and early feeding practices are associated with the likelihood of meeting the Dietary Guidelines for Americans (DGA) recommendation for added sugars (AS) at age 3 years. METHODS: Using data from the WIC Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2), logistic regression assessed associations between WIC participation patterns, early feeding practices, and whether 3-year-olds met the AS recommendation. RESULTS: Children introduced to sugar-sweetened beverages (SSBs) in their first year were about half (adjusted odds ratio, 0.65; P < 0.01) as likely to meet the recommendation as those not exposed in their first 2 years. First-year-only WIC participation (adjusted odds ratio, 0.61; P < 0.04) also increased the risk of excessive consumption compared with children who participated in their third year. CONCLUSIONS AND IMPLICATIONS: Duration of WIC participation is inversely associated with young children's AS intakes. Public health efforts to reduce WIC attrition and enhance education efforts focused on delaying sugar-sweetened beverage introduction are supported.

Vitamin D Intake and Meeting Recommendations Among Infants Participating in WIC Nationally.

OBJECTIVE: To report and examine associations with infant vitamin D intake and meeting recommendations among a national sample participating in Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). DESIGN: Secondary analysis from the 2013-2015 WIC Infant Toddler Feeding Practices Study-2. PARTICIPANTS: US Infants. VARIABLES MEASURED: Total reported vitamin D intake from diet and supplementation at the time of data collection. ANALYSIS: Descriptive statistics and generalized estimating equations. RESULTS: The median total vitamin D intake ranged from 5.43 (95% confidence interval, 5.40-5.46) mcg/d at month 1 to 8.18 (95% confidence interval, 8.11-8.20) mcg/d at month 13, with 16% to 36% of infants meeting the infant vitamin D recommendation over that time. Overall, 6% to 12% of all participants reported supplementation across all time points. Although most (between 78% to 98%) of supplemented breastfed infants met the recommendation, very few were supplemented as a group. Hence, breastfed infants were less likely to meet the recommendation than those who were formula fed across at time points except month 1 (P < 0.001 for all). Whereas infant age, feeding type, and/or their interaction were significant predictors of both receiving supplementation and meeting the recommendation, mother/caregiver nativity (P = 0.006) and parity (P = 0.01 and P < 0.001) predicted receiving supplementation, and child sex (P < 0.001) and mother/caregiver race/ethnicity (P < 0.001) predicted meeting the recommendation. CONCLUSIONS AND IMPLICATIONS: Among a national sample of infants participating in WIC between 2013-2015, a high proportion were not meeting the current vitamin D recommendation. The WIC program is 1 resource for promoting strategies for increasing the number of American infants meeting D recommendations, but a coordinated approach involving other health care providers is likely needed. Future research exploring the reason for lack of supplementation, from both the perspective of parents and providers and the clinical impact of low vitamin D intake, is warranted.

Longer Participation in the Special Supplemental Nutrition Program for Women, Infants, and Children Is Not Associated with Reduced Sugar-Sweetened Beverage Intake among Black Participants.

This study assessed relationships of duration of family Special Supplemental Nutrition Program for Women, Infants and Children (WIC) participation with racial/ethnic disparities in child sugar-sweetened beverage (SSB) and water intake. Child beverage intake and family duration on WIC were collected during three cross-sectional surveys of WIC-participating families in Los Angeles County, California (2014, 2017 and 2020; n = 11,482). The associations of family duration of WIC participation, a proxy for the amount of WIC services received, with daily intake of total SSBs, fruit-flavored SSBs and water were assessed in race/ethnicity strata with multivariable negative binomial and Poisson regression models. Among English-speaking Hispanic children, those of families reporting 10 years of WIC participation consumed 33% and 27% fewer servings of total and fruit-flavored SSBs compared to those of families reporting 1 year on WIC. Among Black children, those from families reporting 5 and 10 years of participation in WIC consumed 33% and 45% more daily servings of fruit-flavored SSBs than those from families reporting 1 year on WIC. Disparities in daily total and fruit-flavored SSB intake between Black and White children increased with longer family duration on WIC. Duration of family WIC participation is associated with healthier beverage choices for infants and children, but does not appear to be equally beneficial across racial/ethnic groups in Los Angeles County.

Age of Bottle Cessation and BMI-for-Age Percentile among Children Aged Thirty-Six Months Participating in WIC.

Background: Children's age at bottle weaning typically ranges from 12 to 24 months. The recommended age of bottle weaning varies. The American Academy of Pediatrics recommends weaning by 12 months; The American Academy of Pediatric Dentistry recommends 12-15 months; The US Department of Agriculture recommends 18 months. Prolonged bottle use is associated with dental caries, iron-deficiency anemia, and child overweight or obesity. We examined factors associated with age of bottle cessation, and the association between age of bottle cessation and BMI-for-age percentile at age 36 months among Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participants. Methods: Data were from the WIC Infant and Toddler Feeding Practices Study-2 (ITFPS-2). The ITFPS-2, a longitudinal study of WIC participants (mothers and their children) began in 2013. We used Cox proportional hazards models to identify factors associated with bottle cessation and multivariate linear regression to examine the association between age of bottle cessation and BMI. Results: About 34% of children used a bottle longer than 12 months, and 13% longer than 18 months. Bottle cessation at older ages was associated with Hispanic ethnicity, multiparity, low income, low education, higher caregiver weight, and not initiating breastfeeding. The adjusted children's BMI-for-age percentile at age 36 months increased by 0.47 for each additional month of bottle use. Conclusion: Prolonged bottle use was associated with increased children's BMI-for-age percentile. Future research is warranted to determine the optimal age to recommend bottle cessation for WIC participants.

Dietary Quality of Pregnant Women Participating in the Special Supplemental Nutrition Program for Women, Infants, and Children.

Few studies have examined the dietary intake of low-income pregnant women participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). The aim of this study was to assess the dietary quality of WIC-enrolled pregnant women and examine associations with maternal characteristics, nutrition knowledge, and key health indicators. Fifty-one WIC-enrolled pregnant women completed two sets of 3-day food records. Food records were analyzed for nutrient content, and diet quality was assessed using the Healthy Eating Index (HEI)-2015. Since an HEI score of less than 60 is indicative of the need to improve dietary quality, participants' HEI scores were divided into two categories: <60 and ≥60. The total mean HEI score of the cohort based on analysis of the first set of food records was 59.1 ± 12.5 (range 37.1-89.2), while the mean score for the second 3 days of food records was 56.8 ± 12.7 (range 30.0-89.0). The majority of participants did not consume the minimum recommended servings of whole vegetables. Those in the <60 HEI category consumed on average less than 50% of the recommended servings of whole fruits and whole grains. The diets of the majority of participants were high in saturated fat and sodium. More than one-third did not meet the recommendations for folate and iron intake, while less than half met the RDA for vitamin D. Choline intake was insufficient based on analysis of the first 3 days of food records. Our results indicate that the dietary quality of WIC-enrolled pregnant women requires improvement.

Prenatal perception of breastfeeding recommendations predicts early breastfeeding outcomes of participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

BACKGROUND: Prenatal psychosocial factors predict breastfeeding practices but are not assessed in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). OBJECTIVES: This study examined how prenatal perceptions of WIC's breastfeeding recommendations were associated with early breastfeeding outcomes. METHODS: This study used longitudinal data from a national sample of 2053 pregnant participants in the WIC Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2) in 2013, the only national data assessing prenatal perceptions of WIC's breastfeeding recommendations. Early breastfeeding outcomes included breastfeeding initiation, breast milk first fed after birth, breastfeeding in the first hour, breast milk first fed after leaving the hospital, and breastfeeding status at the first and third months. The primary predictor was the participant's prenatal perception of whether WIC recommended breastfeeding only or not. Log-binomial regression was used with adjustment for socio-demographics, previous breastfeeding, WIC participation, breastfeeding support, and infant feeding intentions (IFI). RESULTS: Without controlling for IFI, the perception of WIC recommending breastfeeding only predicted breastfeeding outcomes positively. The risk ratio (RR) associated with prenatal perceptions varied from 1.14 (95% CI: 1.03, 1.25; P = 0.008) for breastfeeding in the first hour, to 1.27 (95% CI: 1.12, 1.43; P < 0.001) for breast milk first fed after leaving hospital, to 1.66 (95% CI: 1.35, 2.04; P < 0.001) for 3-mo breastfeeding only. After controlling for IFI, the RRs were 1.13 (95% CI: 1.02, 1.24; P = 0.017) for breastfeeding in the first hour, 1.20 (95% CI: 1.06, 1.35; P = 0.004) for breast milk first fed after leaving hospital, and 1.49 (95% CI: 1.21, 1.84; P < 0.001) for 3-mo breastfeeding only, suggesting that prenatal perception was independently associated with breastfeeding outcomes. CONCLUSIONS: Prenatal perception of WIC's breastfeeding recommendations can be regarded as a new psychosocial predictor of breastfeeding and a possible target for future intervention.

Process Evaluation of a Farm-to-WIC Intervention.

BACKGROUND: Despite the promise of farm-to-institution interventions for addressing limited vegetable access as a barrier to intake, programs designed for the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) are lacking. As such, little is known about the implementation of, and mechanisms of action through which, farm-to-WIC interventions affect vegetable intake and participant satisfaction with such programs. OBJECTIVE: To examine whether a farm-to-WIC intervention to promote vegetable intake was implemented as intended, differences between participants who received the intervention relative to those in a usual-care control group in intermediate outcomes of vegetable-related knowledge, attitudes, and behaviors, and secondary outcomes of physical activity and weight status; and participant satisfaction with the intervention. DESIGN: A process evaluation encompassing descriptive and comparative analyses of implementation fidelity logs and survey data collected as part of a pilot study was conducted. PARTICIPANTS/SETTING: The setting was a large, New Jersey-based, urban WIC agency. Recruited between June 3 and August 1, 2019 through 3 of the agency's 17 sites (1 intervention and 2 control sites), participants were 297 primarily Hispanic adults (160 enrolled at the intervention site and 137 at control sites). INTERVENTION: The intervention combined behaviorally focused instruction and handouts with the introduction of a WIC-based farmers' market, field trips to an area farmers' market, telephone coaching and support, and recipe demonstrations and tastings. MAIN OUTCOME MEASURES: Primary outcomes were vegetable intake (measured via self-report and objectively using dermal carotenoids as a biomarker of intake) and the redemption of vouchers provided by WIC for fruit and vegetable purchases at farmers' markets (measured objectively using data provided by WIC). For the process evaluation, logs were used to document program activities. Vegetable-related knowledge, attitudes, and behaviors, physical activity, and satisfaction with the intervention were assessed with participant questionnaires. Weight status was assessed with direct measures of height and weight. Data were collected at baseline and at mid- and post-intervention (3 and 6 months post-baseline, respectively). STATISTICAL ANALYSES PERFORMED: Descriptive statistics were used to characterize implementation fidelity. Associations between intermediate and secondary outcomes and vegetable intake were examined at baseline with Pearson correlations. Post-baseline between-group differences in the outcomes were examined with linear mixed-effects models adjusted for baseline values and covariates. Satisfaction with the intervention was assessed with inferential and thematic analyses. RESULTS: Post-intervention, measures of vegetable intake were higher in the intervention relative to the control study group. Receipt of the intervention was also associated with a greater likelihood of voucher redemption. Nearly all participants (≥94%) received the intervention as intended at the WIC-based farmers' market; smaller percentages completed 1 or more planned trips to the area farmers' market (28%) and telephone coaching and support calls (88%). Although most intermediate and secondary outcomes were associated with measures of vegetable intake at baseline, the variables did not differ between study groups post-intervention. Mean satisfaction ratings were ≥6.8 on a 7-point scale. Recipe demonstrations, learning about vegetables, field trips, and the rapport with staff were liked most about the program. Although adding days and times for field trips was suggested, limited market days and hours of operation limited the ability to do so. CONCLUSIONS: Preliminary data highlight the promise of this well-received intervention. Intermediate outcome findings suggest that other potential intervention mechanisms of action should be considered in future large-scale trials of this program. Broad-scale initiatives are needed to improve access to farmers' markets in underserved communities.

The Magnitude and Determinants of Partial Redemptions of Food Benefits in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC).

PURPOSE: WIC provides food assistance to low-income pregnant and postpartum women, infants, and children ages 1- 4. A partial redemption (PR) occurs when a participant redeems only a portion of the prescribed benefit, thereby not obtaining the full nutritional benefit. We study the magnitude and determinants of PRs using electronic benefit transfer data. DESIGN/SETTING: Statistical analysis of all WIC transactions from Feb 2016 to Nov 2018. SUBJECTS: Oklahoma WIC participants. MEASURES: The probability of a WIC household fully redeeming a food category. A random effects probit model is used to study determinants of PRs. ANALYSIS: Estimate the marginal effects of key variables on households' likelihood of full redemption: location-urban/rural, number of members in WIC, duration in the program, number of shopping trips, shopping venue, and prescribed foods. RESULTS: Overall 18.5% of $ value of benefits are unredeemed, 29.3% excluding formula. Some foods have PRs > 40%. Only 17.3% of households fully redeem benefits in a given month. PRs increase with number of household members in WIC and duration of participation. PRs are lower for participants in rural locations, who shop more frequently, and who shop at WIC-specialized stores. CONCLUSIONS: Food packages with high PRs fail to impart prescribed benefits. Results pinpoint products and household characteristics associated with PRs, enabling targeted nutritional counseling and suggest food package choices need to be made with participant acceptance in mind.

Pilot Study of a Farm-to-Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Intervention Promoting Vegetable Consumption.

BACKGROUND: Vegetable intake is below recommended levels among adults served by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). OBJECTIVE: The aim of this study was to determine whether a novel, theory-driven, farm-to-WIC intervention to promote vegetable intake showed promise of being successful and is therefore appropriate for efficacy testing. DESIGN: From June 2019 to January 2020, the intervention was piloted in three WIC agency sites (one randomized to the intervention study group and two to the control group) selected based on similarity in size and the demographics of participants served. PARTICIPANTS/SETTING: Recruited between June 3, 2019 and August 1, 2019, participants were 297 primarily Hispanic adults served by a large WIC agency located in a densely populated urban area in New Jersey (160 were enrolled at the intervention site and 137 at control sites). INTERVENTION: The intervention combined behaviorally focused instruction and handouts with the introduction of a WIC-based farmers' market, field trips to an area farmers' market, telephone coaching and support before and after trips, and recipe demonstrations and tastings. MAIN OUTCOME MEASURES: The primary outcomes were vegetable intake (measured objectively using dermal carotenoids as a biomarker of intake and via self-report) and the redemption of vouchers provided through the WIC Farmers' Market Nutrition Program (FMNP) for fruit and vegetable purchases at farmers' markets (objectively assessed using data provided by WIC). STATISTICAL ANALYSES PERFORMED: Between-group differences in vegetable intake were examined at mid- and post-intervention (3 and 6 months post-baseline, respectively) with linear mixed-effects models adjusted for baseline vegetable intake and covariates. Logistic regression analysis was used to relate FMNP voucher redemption to study group and covariates. RESULTS: At mid-intervention, objectively measured vegetable intake was higher among participants in the control group as compared with the intervention group; self-reported intake did not differ by group. Post-intervention, objectively measured and self-reported vegetable intake were higher among participants in the intervention group as compared with the control group. Receipt of the intervention was associated with a greater likelihood of FMNP voucher redemption. Voucher redemption rates were 87% in the intervention group and 28% in the control group (odds ratio = 17.39, 95% confidence interval [8.64, 35.02]). CONCLUSIONS: Meaningful associations found between the intervention, vegetable intake, and FMNP voucher redemption suggest that the program is appropriate for efficacy testing.

Alignment of California WIC Participant Preferences With Proposed WIC Food Package Recommendations.

OBJECTIVE: Assess alignment of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participant preferences with the National Academies of Sciences, Engineering, and Medicine WIC child food package recommendations and compare differences by race/ethnicity. METHODS: Cross-sectional examination of survey responses collected between January and May 2019 from 2,993 California WIC families with children aged 1-4 years. RESULTS: Over half of WIC participants (56.1%) wanted an increase in the amount allocated for fruits and vegetables. Many WIC participants (69.6%) thought the amount of juice offered by WIC was just right. Overall, the majority (91.0%) wanted to substitute more fruits and vegetables for juice. Most were satisfied with the amount of beans (78.4%), peanut butter (78.7%), and milk (88.3%). Preferences differed by race/ethnicity. CONCLUSIONS AND IMPLICATIONS: Preferences of California WIC participants are highly aligned with the proposed National Academies of Sciences, Engineering, and Medicine changes for increasing fruits and vegetables. Notable differences by race/ethnicity suggest the need for more flexibility.

Knowledge Translation and WIC Food Package Regulation Change.

OBJECTIVE: Knowledge Translation (KT) is the exchange, synthesis, and ethically-sound application of knowledge. A case study methodology is used to examine KT at the organizational level of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) program. METHOD: The study used purposeful sampling to select WIC informants from state WIC agencies to participate in semi-structured interviews about their individual experiences during the 2009 WIC regulation change process. Thematic coding of retrospective semi-structured interviews with key informants from WIC state agencies revealed key components of the state-level WIC regulation implementation process, and key constructs of Organizational Readiness for Knowledge Translation in the WIC program. RESULTS: WIC informants highlight that decisions made by WIC state agencies regarding how to appraise, synthesize, and adapt evidence or regulation change are constrained by the KT decisions made by federal agencies. WIC state agencies should assess their level of readiness for KT in terms of 1) innovation readiness; 2) personal readiness; and 3) institutional readiness. CONCLUSIONS: This WIC case study can help decision-makers to understand the KT process of implementing evidence-informed regulation changes, identify factors that could influence states' ability to be prepared for implementing changes, and gauge "practicality" of future WIC regulation changes.

The Special Supplemental Nutrition Program for Women, Infants, and Children is Associated with Several Changes in Nutrient Intakes and Food Consumption Patterns of Participating Infants and Young Children, 2008 Compared with 2016.

BACKGROUND: In 2009 the USDA's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) updated the food packages provided to participants. OBJECTIVES: This study investigates associations between WIC participation and nutrients and food groups consumed using data from the Feeding Infants and Toddlers Study's 2008 and 2016 nationwide, cross-sectional surveys of children <4 y, weighted to be representative of the US population. METHODS: The study data included 2892 children aged 6-47.9 mo in 2008 and 2635 in 2016. Differences were analyzed by WIC participation, survey year, and child age (infants 6-11.9 mo old, toddlers 12-23.9 mo old, preschoolers 24-47.9 mo old). Usual nutrient intake distributions were estimated using National Cancer Institute methodology. Daily food group consumption differences were tested via multivariate regression. All analyses controlled for income. RESULTS: In 2016 18.6% of infants had iron intakes below the estimated average requirement (EAR), compared to 7.6% in 2008; 87% of WIC infants met the EAR, compared with 69% of non-WIC infants. In 2016 37% of WIC preschoolers met saturated fat guidelines, compared with 25% in 2008; in both years, fewer than one-third of non-WIC preschoolers met the guidelines. More WIC infants than non-WIC infants consumed infant cereals in 2016 (58% compared with 45%, respectively). More WIC infants ate vegetables daily in 2016 than in 2008 (74% compared with 59%, respectively).  In 2016, as compared with 2008, more WIC infants consumed baby-food vegetables (55% compared with 29%, respectively) and fruits (56% compared with 41%, respectively). In 2016 47% of WIC preschoolers drank low-fat milk, compared with 19% of non-WIC preschoolers. CONCLUSIONS: Infant iron intakes are concerning, although more WIC infants meet the EAR. WIC infants' vegetable intakes have improved; baby-food vegetables have become important contributors to their intakes. In 2016 WIC children were more likely than non-WIC children to shift to lower-fat milks at 2 y of age, likely contributing to lower saturated fat intakes.

Potential overfeeding among formula fed Special Supplemental Nutrition Program for Women, Infants and Children participants and associated factors.

BACKGROUND: The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) provides enough formula to meet the known nutritional needs of infants up to 6 months of age whose mothers report not breastfeeding, but many mothers report WIC providing insufficient formula, indicating potential overfeeding. OBJECTIVE: To estimate the prevalence of potential overfeeding among formula-feeding WIC participants and identify associated factors. METHODS: Potential overfeeding was identified among participants of the longitudinal Infant and Toddler Feeding Practices Study-2 (ITFPS-2) receiving the fully formula-feeding WIC infant package at 1 month of age (n = 1235, weighted n = 197 079). Associations of potential overfeeding with caloric intake, weight and participant characteristics were assessed. RESULTS: Potential overfeeding was identified among 37.41% (95% CI = 33.57-41.25%) of fully formula-feeding infants. Potentially overfed infants were 0.18 kg heavier (P-value = .01), consumed 26 more calories daily (P-value = .004) and were more likely Non-Hispanic White or English-speaking Hispanic (P-value = .007) and highly active at 5 months of age (P-value = .01). Mothers of potentially overfed infants were less likely to agree that breastfeeding is easier than bottle feeding, only mothers can feed breastfed infants, turning away from the bottle indicates satiation, and crying always indicates hunger (P-values .04, .002, .04 and .04 respectively), and more likely to report WIC provides insufficient formula early (1-5 months, P-value <.0001) and late (6-13 months, P-value = .007) in infancy. CONCLUSIONS: Potential overfeeding occurs in 37% of fully formula-feeding infant WIC-participants <6 months old. Mothers of these infants may benefit from additional education about the formula needs of their infants and how to recognize infant satiation cues.

Differences in Consumption of NASEM Priority Nutrients and Food Groups by Race/Ethnicity Among Women Living in WIC-Participating Households.

PURPOSE: To examine racial/ethnic differences in dietary intake of women in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). DESIGN: Cross-sectional study. SETTING: Data from the US National Health and Nutrition Examination Survey. PARTICIPANTS: Women 19 to 50 years of age living in WIC-participating households. MEASURES: Nutrient/food group intake from one 24-hour dietary recall. ANALYSIS: Multivariable linear regression was used to evaluate the relationship between race/ethnicity and nutrient/food group intake. RESULTS: Compared to non-Hispanic white women, Hispanic women had lower dietary energy density (1.7 ± 0.1 vs 2.2 ± 0.1 kcal/g, P < .001), and better nutrient intake, including more folate (429 ± 20 vs 364 ± 29 µg, P = .024), fiber (20.1 ± 0.9 vs 13.6 ± 0.9 g, P ≤ .001), and potassium (2575 ± 78 vs 2251 ± 66 mg, P = .012). This may be related to greater consumption of total vegetables (1.67 ± 0.16 vs 1.17 ± 0.17 cup equivalents [c-eq], P = .029), including more red and orange vegetables (0.64 ± 0.11 vs 0.32 vs 0.09 c-eq, P = .013) and more legumes (0.17 ± 0.04 vs 0.07 ± 0.02 c-eq, P = .006). Both Hispanic and non-Hispanic black women consumed more sodium (Hispanic: P = .015; non-Hispanic black: P = .008), but less added sugars (Hispanic: P ≤ .001; non-Hispanic black: P = .015), than non-Hispanic white women. CONCLUSION: These findings highlight differences in dietary intake by race/ethnicity and can inform nutrition messages of WIC nutrition educators and dietitians.

Integrating Data To Advance Research, Operations, And Client-Centered Services In California.

The value of using administrative records for operational and evaluation purposes has been well established in health and human services. However, these records typically reflect the reach of a single government agency or program and fail to capture the experiences of individuals as they engage with different agencies or programs over time. Thus, the potential for these data to improve everyday operations, coordinate services, develop targeted interventions, and advance the science behind broader social policies has yet to be fully realized. A first step toward realizing that potential is to transition from an agency-centered to a client- or person-centered organization of data. We systematically linked tens of millions of records across California's largest health and human services programs. Our results underscore how the integration of records can help shift discussions from the programs that administer services to the people who are served.
