Differences in Infant Diet Quality Index by Race and Ethnicity Predict Differences in Later Diet Quality

BackgroundRacial and ethnic disparities in infant-feeding practices may negatively influence diet quality and health. ObjectivesThis study investigated the racial, ethnic, and language (English or Spanish) differences in infant diet quality, later diet quality, and weight status at 2–5 y, and whether these differences were explained through infant diet quality among participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). MethodsUsing the WIC Infant and Toddler Feeding Practices Study-2 (unweighted n = 2663; weighted n = 362,712), relationships between the Infant Dietary Quality Index (IDQI; range 0–1) and Healthy Eating Index-2020 (HEI-2020; range 0–100) and BMI z-score (BMIz) at 2–5 y were analyzed by race, ethnicity, and language preference [Hispanic Spanish-speaking, Hispanic English-speaking, non-Hispanic (NH) White, and NH Black participants]. Statistical interaction between IDQI and each group was evaluated in multivariable models. The mediation of each group through the IDQI was assessed using causal mediation methods. ResultsDifferences in IDQI [mean (standard deviation)] were observed between Hispanic Spanish-speaking participants [0.41 (0.10)], Hispanic English-speaking participants [0.37 (0.10)], NH White participants [0.36 (0.10)], and NH Black participants [0.35 (0.09)], P < 0.001. Differences in HEI-2020 occurred at 2–5 y, with the Hispanic Spanish-speaking participants having consistently higher HEI-2020 scores. Differences in BMIz were observed at 5 y, with higher scores among Hispanic Spanish-speaking participants. Interaction between race, ethnicity, and IDQI was observed for all outcomes except for BMIz at 3 y. Through mediation, IDQI explained 13%–20% of the difference in HEI-2020 scores between Hispanic Spanish-speaking and NH White participants at 2–5 y. IDQI explained 22%–25% of the difference in HEI-2020 scores between the Hispanic Spanish-speaking and NH Black participants at 4 y and 5 y. ConclusionsHigher infant diet quality scores observed in Hispanic Spanish-speaking participants explain some of the racial and ethnic differences observed in later diet quality, suggesting that improving infant diet quality may help reduce diet disparities during early childhood.

Early introduction of complementaryfoods/drinks and milk feeding type in the Special Supplemental Nutrition Program for Women, Infantsand Children (WIC).

Infants younger than 4 months are not ready for complementary foods/drinks (any solid or liquid other than breast milk or infant formula). Almost half of USinfants participate in the Special Supplemental Nutrition Program for Women, Infantsand Children (WIC), which provides nutrition education and support to low-income families. We describe the prevalence of early introduction (<4 months) of complementary foods/drinks and examine the association of milk feeding type (fully breastfed, partially breastfedor fully formula fed) with early introduction of complementary foods/drinks. We used data from 3310 families in the longitudinal WIC Infant and Toddler Feeding Practices Study-2.We described the prevalence of early introduction of complementary foods/drinks and modeled the association of milk feeding type at Month 1 with early introduction of complementary foods/drinks using multi-variable logistic regression. Thirty-eight percent of infants were introduced early to complementary foods/drinks (<4 months). In adjusted models, infants who were fully formula fed or partially breastfed at Month 1 were 75% and 57%, respectively, more likely to be introduced early to complementary foods/drinks compared with fully breastfed infants. Almost twoin fiveinfants were given complementary foods/drinks early. Formula feeding at Month 1 was associated with higher odds of early introduction of complementary foods/drinks. There are opportunities to support families participating in WIC to prevent early introduction of complementary foods/drinks and promote child health.

Implementation of a sample design for a survey of program participants using time-location sampling.

To assess the feeding practices and behaviors of women and young children participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), USDA currently funds the longitudinal WIC Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2). In 2013, the study used time-location sampling (TLS) to enroll a cohort of infants who participated in WIC around birth. The children are subsequently followed across their first six years of life, regardless of their participation in WIC, with an additional follow-up at age nine years. A woman may enroll her child in WIC either during pregnancy or postpartum. For this study, a representative sample of infants enrolled in WIC was desired. Because the associations between WIC prenatal support and education and feeding practices and behaviors are substantively important to this study, the sample needed to include both women enrolling their children prenatally and women enrolling their children postnatally. For prenatal WIC enrollees, we attempted to complete a prenatal interview with the mother prior to the child's birth. This paper describes the TLS approach used and the challenges addressed in implementation of the sample design and selection for the WIC ITFPS-2. Our approach generated a probability sample (subject to site geographic and size exclusions) using a stratified, multistage design, but there were challenges at each stage of selection. First, a WIC site was selected, and then newly enrolled WIC participants were sampled within selected sites during predetermined recruitment windows based on the site's average flow of new WIC enrollees. We discuss issues faced, including overcoming incomplete lists of individual WIC sites and discrepancies between projected new WIC enrollment counts and actual flow of new WIC enrollments during the recruitment period.

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

BackgroundHealthy 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. ObjectiveThe 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. DesignData 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.) ResultsThe total IDQI score was positively associated with HEI-2015 at the age of 2 y (β = 16.7; 95% CI: 12.6, 20.9; P < 0.001), 3 y (β = 14.5; 95% CI: 8.1, 21.0; P < 0.001), and 4 y (β = 15.4; 95% CI: 8.4, 22.4; P < 0.001); and negatively associated with BMIz at the age of 2 y (β = -1.24; 95% CI: -2.01, -0.47; P = 0.002) and 4 y (β = -0.92; 95% CI: -1.53, -0.30; P = 0.003). ConclusionsThe IDQI has predictive validity for diet quality and weight status in low-income US children.

Comparing Diet Quality Indices for Low-Income 24-Month-Old Toddlers: Exploring Changes Driven by 2020–2025 Dietary Guidelines for Americans

BackgroundAccurate assessment of toddler diet quality is essential for understanding current intakes and evaluating the effect of interventions and programs to promote healthy eating and prevent chronic disease. ObjectivesThe goal of this article was to assess the diet quality among toddlers using two different indices appropriate for 24-mo-old toddlers and compare differences in scoring between the measures by race and Hispanic origin. MethodsWe used cross-sectional data from 24-mo-old toddlers participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Infant and Toddler Feeding Practices Study-2 (ITFPS-2), a national study that includes 24-hour dietary recall information from children enrolled in WIC at birth. The main outcome measure was diet quality using both the toddler diet quality index (TDQI) and the healthy eating index (HEI)-2015. We derived mean scores for overall diet quality and for each component. We examined associations between the distribution of diet quality scores across terciles and by race and Hispanic origin using Rao-Scott chi-square tests of association. ResultsNearly half of the mothers and caregivers self-identified as Hispanic (49%). Diet quality scores were higher when using the HEI-2015 compared with the TDQI (56.4 vs. 49.9, respectively). The difference in component scores was largest for refined grains, followed by sodium, added sugars, and dairy. Toddlers from Hispanic mothers and caregivers had significantly higher component scores for greens and beans and dairy but had lower scores for whole grains (P < 0.05) than those for the other racial and ethnic subgroups assessed. ConclusionsWe found noteworthy differences in toddler diet quality depending on whether the HEI-2015 or TDQI is used, and children of different racial and ethnic subgroups may be differentially classified as having high or low diet quality depending on which index is used. This may have important implications for understanding which populations are at risk of future diet-related diseases.

Prenatal Perception of WIC Breastfeeding Recommendations Predicts Breastfeeding Exclusivity and Duration in the Infants’ First Year

Pregnant participants who perceived that the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) recommends breastfeeding only were more likely to have better early breastfeeding outcomes. Our objective was to examine the association between prenatal perception of WIC's breastfeeding recommendations and breastfeeding duration through the first year of infant life. This observational study used a national longitudinal sample of 1594 pregnant participants in the WIC Infant and Toddler Feeding Practices Study-2 in 2013. Four measures of breastfeeding duration were used: 1) a discrete measure of exclusive breastfeeding through 5 mo; 2) a continuous measure of exclusive breastfeeding (in days up to 7 mo); 3) a discrete measure of any breastfeeding through 11 mo; and 4) a continuous measure of any breastfeeding (in days up to 13 mo). The primary explanatory variable was the participant's prenatal perception of whether WIC recommended breastfeeding only. The univariate analyses of time to breastfeeding cessation were performed using Kaplan-Meier curves. The Cox regression model was adopted to estimate the likelihood of breastfeeding outcomes over time. All analyses accounted for complex survey design effects. Compared with their peers who perceived WIC to recommend formula only or both breastfeeding and formula equally, participants who perceived WIC as recommending breastfeeding only were less likely to stop exclusive breastfeeding through 5 mo (HR = 0.83; 95% CI: 0.69, 0.99) or to stop any breastfeeding through 11 mo (HR = 0.80; 95% CI: 0.69, 0.92), without controlling for prenatal infant feeding intentions. Similar patterns were observed in the 2 continuous measures, as they were also less likely to stop exclusive breastfeeding by 7 mo (HR = 0.78; 95% CI: 0.69, 0.90) or to stop any breastfeeding by 13 mo (HR = 0.82; 95% CI: 0.71, 0.95). Prenatal perception of WIC's breastfeeding recommendation can be a useful predictor of breastfeeding duration in WIC participants.

Longer Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Participation Duration Is Associated with Higher Diet Quality at Age 5 Years

BackgroundThe Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides supplemental healthy foods and nutrition education to children under age 5 y in low-income households. ObjectivesWe aimed to identify characteristics associated with duration of WIC participation and assess how participation duration relates to household food insecurity (HFI), child diet quality, and child weight status at age 60 mo. MethodsThis analysis of the WIC Infant and Toddler Feeding Practices Study-2, a prospective cohort of WIC-participating children enrolled in 2013, included children with complete baseline–60 mo data (n = 836). Outcomes assessed with WIC participation duration in multivariable regression were HFI (USDA 6-item Household Food Security Screener), child diet quality on a given day [Healthy Eating Index (HEI)-2015], and obesity (CDC BMI-for-age ≥95th percentile). ResultsFactors associated with longer WIC participation included male sex; lower household income; reported diet changes in response to WIC nutrition education; household Supplemental Nutrition Assistance Program participation; English-speaking Hispanic, Spanish-speaking Hispanic, and non-Hispanic other maternal race-ethnicity and language preference; an ever-married mother; lower maternal education; higher maternal age; earlier enrollment during pregnancy; and reporting a subsequent pregnancy. Longer WIC participation was associated with lower HFI odds (OR: 0.69; 95% CI: 0.51, 0.95), higher total HEI-2015 (β: 0.73; 95% CI: 0.20, 1.25), and higher obesity odds (OR: 1.20; 95% CI: 1.05, 1.37) in multivariable-adjusted regression models. ConclusionsLonger WIC participation was associated with reduced HFI and higher diet quality, and unexpectedly with higher obesity odds, at 60 mo. Further research is needed to confirm and understand mechanisms underlying the unexpected associations identified with longer WIC participation (e.g., male sex, obesity). Groups with shorter participation durations may benefit from targeted WIC retention efforts to maximize nutrition security.

Prenatal Perception of WIC Breastfeeding Recommendation Predicts Breastfeeding Outcomes in Infant’s First Year

ObjectivesPromoting breastfeeding (BF) is a priority of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Prior research found that pregnant mothers who believed WIC recommends BF only (versus BF and formula equally OK) were more likely to initiate BF and continue through 1 month postpartum. We examine whether such mothers are more likely to continue to exclusively BF through 5 months and BF at all through the infant's first year.MethodsData are from the WIC Infant and Toddler Feeding Practices Study-2 (ITFPS-2), a longitudinal study that includes 2,649 mothers who completed prenatal interviews. Four BF outcomes were examined: (a) exclusive BF through 5 months, (b) any BF through 11 months, (c) age of the infant (in days up to 7 months) when formula is initiated, and (d) age of the infant (days up to 13 months) when mother stopped BF. We examined the associations of prenatal belief that WIC recommended BF only (yes/no) with each BF outcome using the Cox regression model to estimate the likelihood of breastfeeding outcomes over time while controlling for prenatal infant feeding intention (IFI) and socio-demographic factors. All analyses accounted for complex survey design effects.ResultsOf the pregnant mothers, 41% perceived that WIC recommends BF only; 59% perceived that WIC recommends BF and formula equally. Mothers who perceived WIC to recommend BF only were less likely to initiate formula by 7 months than those who perceived WIC recommended BF and formula equally [Hazard Ratio (HR) = 0.84; P < 0.05], after controlling for IFI.WIC perception was a significant predictor only when IFI was not controlled for the other three BF outcomes: stopped exclusive BF through 5 months (HR = 0.83; P < 0.05), stopped any BF through 11 months (HR = 0.80; P < 0.01), and stopped any BF by 13 months (HR = 0.82; P < 0.01).ConclusionsPerception of WIC BF recommendation can be a significant predictor of BF outcomes in the infant's first year, possibly by affecting BF intention.Funding SourcesITFPS-2 is funded by the Food and Nutrition Service, U.S. Department of Agriculture (USDA). Support for the study analysis was provided by the Economic Research Service, USDA CRA 58–4000-8–0038-R.

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

ObjectiveTo 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. MethodsUsing 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. ResultsChildren 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 ImplicationsDuration 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.

The Relationship between Breastfeeding and Initial Vegetable Introduction with Vegetable Consumption in a National Cohort of Children Ages 1-5 Years from Low-Income Households.

Compared to other food groups, vegetable intakes are lowest relative to recommendations. Breastfeeding and initial introduction to vegetables may help infants establish long-lasting taste preferences. We examined the relationship between breastfeeding and initial vegetable introduction and vegetable intake in early childhood (ages 13–60 months). This repeated cross-sectional study used data from the national WIC Infant and Toddler Feeding Practices Study-2 collected from low-income mother/caregivers about infants from around birth through age 5 (60 months; n = 3773). Survey-weighted adjusted regression models assessed associations between breastfeeding and vegetable introduction measures with vegetable consumption at child ages 13, 24, 36, 48, and 60 months. Longer breastfeeding duration was associated with a slightly, but significantly, greater variety of vegetables consumed/day in early childhood. There was also a small but positive statistically significant association between the number of different types of vegetables consumed on a given day at 9 months and the amount and variety of vegetables consumed/day in early childhood. Age of initial vegetables introduction and whether vegetables were the first/second food introduced were not consistently related to the amount or variety of vegetables consumed later in childhood. Longer breastfeeding and introduction to a greater variety of vegetables at 9 months may be behaviors to target to increase consumption of a greater variety of vegetables by young children.

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

ObjectiveTo 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). DesignSecondary analysis from the 2013–2015 WIC Infant Toddler Feeding Practices Study-2. ParticipantsUS Infants. Variables MeasuredTotal reported vitamin D intake from diet and supplementation at the time of data collection. AnalysisDescriptive statistics and generalized estimating equations. ResultsThe 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 ImplicationsAmong 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.

Duration of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Participation is Associated With Children's Diet Quality at Age 3 Years

Adequate childhood nutrition contributes to prevention of chronic diseases. The supplemental foods and nutrition education provided by the Special Supplemental Nutrition Program for Women, Infants, and Children, a federal program serving women, infants, and children up to age 5 years in low-income families and at nutritional risk, intend to optimize dietary intakes. This study assesses associations between duration of the Special Supplemental Nutrition Program for Women, Infants, and Children participation, early feeding practices, and children's diet quality at age 3 years. Using data collected between 2013 and 2017 from the Special Supplemental Nutrition Program for Women, Infants, and Children Infant and Toddler Feeding Practices Study-2, investigators derived 4 mutually exclusive patterns of the Special Supplemental Nutrition Program for Women, Infants, and Children participation: participation in the child's first year only, participation into the second year, participation into the third year, and intermittent participation across 3 years. In 2021, multivariable regression assessed associations between these patterns, early feeding practices, and 2015 Health Eating Index total score at age 3 years. When compared with children who participated in the Special Supplemental Nutrition Program for Women, Infants, and Children into their third year, children who participated in their first year only (p<0.01) had 2015 Healthy Eating Index total scores that were 3.6 points lower on a given day. Children introduced to sugar-sweetened beverages in their first year had scores that were 2.4 points lower than children not introduced to them in their first 2 years (p=0.03), whereas those breastfed longer exhibited a small increase in scores (p<0.01). Longer participation in the Special Supplemental Nutrition Program for Women, Infants, and Children improves children's diets, potentially mitigating chronic disease risk. Clinician efforts to refer at-risk families to the Special Supplemental Nutrition Program for Women, Infants, and Children during the early childhood years are supported.

Maternity Care Practices and Breastfeeding Intentions at One Month Among Low-Income Women.

Maternity care practices have been linked with higher chances of meeting breastfeeding intentions, but this relationship has not been examined using national data on US low-income women enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Using data from the WIC Infant and Toddler Feeding Practices Study-2 on 1080 women who intended to breastfeed, we estimated risk ratios for associations between (1) each of 6 maternity care practices supportive of breastfeeding (breastfeeding within 1 hour of birth, showing mothers how to breastfeed, giving only breast milk, rooming-in, breastfeeding on demand, no pacifiers), (2) each practice adjusted for all other practices, and (3) total number of practices experienced with whether women met their intention to feed only breast milk at 1 month old. Models were adjusted for demographics. In adjusted models (1), breastfeeding within 1 hour of birth, giving only breast milk, and no pacifiers were associated with higher likelihood of meeting prenatal breastfeeding intentions. Adjusting for all other practices (2), initiating breastfeeding within 1 hour of birth (risk ratio: 1.3; 95% confidence interval: 1.0-1.6) and giving only breast milk (risk ratio: 4.4; 95% confidence interval: 3.4-5.7) remained associated with meeting breastfeeding intention. There was a dose-response relationship between number of steps experienced and higher likelihood of meeting prenatal breastfeeding intentions (3). Women who experienced maternity care practices supportive of breastfeeding were more likely to meet their prenatal breastfeeding intentions, underscoring the importance of breastfeeding support during the birth hospitalization in enabling mothers to achieve their breastfeeding goals.

Postpartum Symptoms of Depression are Related to Infant Feeding Practices in a National WIC Sample

ObjectiveTo examine the association between elevated maternal postpartum depression symptoms and select targets of nutrition education within the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), including infant feeding beliefs, feeding practices, and dietary intake choices. DesignLongitudinal analysis of secondary data from the WIC Infant and Toddler Feeding Practices Study-2. SettingEighty WIC sites. ParticipantsThe WIC Infant and Toddler Feeding Practices Study-2 participants interviewed through 13 months postpartum (n = 1,851). Main Outcome MeasuresLatent factor variables for infant feeding beliefs, feeding practices, and dietary intake choices. AnalysisConfirmatory factor analysis using structural equation modeling; multivariable linear regression models. ResultsBiological mothers with elevated postpartum depression symptoms engaged in significantly less optimal feeding practices than biological mothers with fewer symptoms of depression, in multivariable analyses controlling for sociodemographic variables (β = −0.26; P = 0.02). Maternal depression symptoms were not significantly associated with infant feeding beliefs or dietary intake choices. Conclusions and ImplicationsMaternal depression symptoms are specifically associated with infant feeding practices. The Special Supplemental Nutrition Program for Women, Infants, and Children could consider screening for depressive symptoms and referring mothers for treatment. For mothers with elevated depression symptoms, nutrition education may need greater emphasis on healthy and safe feeding practices.

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

Prenatal psychosocial factors predict breastfeeding practices but are not assessed in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). This study examined how prenatal perceptions of WIC's breastfeeding recommendations were associated with early breastfeeding outcomes. 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). 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. Prenatal perception of WIC's breastfeeding recommendations can be regarded as a new psychosocial predictor of breastfeeding and a possible target for future intervention.

Shifts in Sources of Food but Stable Nutritional Outcomes among Children in the Early Months of the COVID-19 Pandemic.

Early in the COVID-19 pandemic, the U.S. Department of Agriculture (USDA), State governments, and school districts took unprecedented steps to mitigate the pandemic’s impact on students’ nutrition. To examine the effect of emergency responses on 6-year-old children’s nutritional outcomes, this study analyzed longitudinal data from a national study of children’s feeding practices, the Special Supplemental Nutrition Program for Women, Infants, and Children—Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2). Findings include no differences in food insecurity prevalence; however, there were shifts in sources of food, with children in the post-COVID-emergency-declaration (post-ED) group consuming more dietary energy from stores and community food programs and less from restaurants and schools than children in the pre-COVID-emergency-declaration (pre-ED) group (p < 0.01 for all comparisons). Examination of within-person mean differences in 2015 Healthy Eating Index scores and nutrient intakes between ages 5 and 6 years revealed few statistically significant differences between the two groups: children in the post-ED group consumed slightly fewer vegetables (p = 0.02) and less sodium (p = 0.01) than their pre-ED peers. Findings suggest emergency efforts to maintain children’s nutrition were largely successful in the early months of the pandemic. Research is needed to understand the mechanisms by which emergency efforts contributed to these findings.

Factors Associated with the Initiation of Added Sugar among Low-Income Young Children Participating in the Special Supplemental Nutrition Program for Women, Infants, and Children in the US.

Added sugar intake at a young age is associated with chronic diseases including cardiovascular diseases, asthma, elevated blood pressure, and overweight. The Dietary Guidelines for Americans 2020–2025 and the American Heart Association recommend delaying the introduction of added sugar until age 2. The aims of this study were to identify the timing of added sugar initiation; factors associated with added sugar initiation; and the top five added sugar foods and beverages consumed by infants and children at three age ranges (<7 months, 8–13 months, and 14–24 months). Data were from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Infant and Toddler Feeding Practices Study-2, a longitudinal, national population of WIC participants enrolled in WIC eligible clinics (n = 3835). The Cox proportional hazards model was used to examine the factors associated with introducing added sugar. About 25% of children were given added sugar at or before 7 months. Contributing factors were caregivers’ race/ethnicity, education, employment, weight status, parity, child sex, and premature birth (all p < 0.05). The top added sugar foods consumed between 1–24 months were cereal, crackers, apple sauce, dessert, yogurt, sweetened beverages, syrup and preserves, and cookies. Further research to examine the impact of early initiation of added sugar on health outcomes and taste preferences is warranted.

Mixed Infant Feeding Is Not Associated With Increased Risk of Decelerated Growth Among WIC-Participating Children in Southern California.

Background: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides nutrition assistance to half of infants born in the United States. The nationally representative WIC Infants and Toddler Feeding Practices Study-2 (ITFPS-2) reported a caloric deficit at 7 months among infants receiving WIC mixed feeding packages, suggesting these infants may be at risk for growth deceleration/faltering.Methods: Longitudinal administrative data collected prospectively from WIC participants in Southern California between 2010 and 2019 were used (n = 16,255). Infant lengths and weights were used to calculate weight-for-length (WLZ), weight-for-age (WAZ) and length-for-age (LAZ) z-scores at different time points. Growth deceleration/faltering was determined at 9, 12, 18, and 24 months by the change in z-score from the last measurement taken ≤ 6 months of age. Infant feeding was categorized by the food package (breastfeeding, mixed feeding, and formula feeding) infants received from WIC at 7 months. Poisson regression models were used to evaluate the association between WIC infant package at 7 months and deceleration/faltering at 9, 12, 18, and 24 months.Results: The proportion of infants displaying decelerated/faltering growth was low for all infant food package groups. Receiving the WIC mixed feeding package at 7 months of age was not associated with WLZ, WAZ, and LAZ deceleration/faltering growth.Conclusions: Growth deceleration/faltering rates were very low among WIC participating children in Southern California, highlighting the critical role of nutrition assistance in supporting adequate growth in early childhood.

Food Preparation Practices for Infants Aged From 7 to 13 Months

ObjectiveTo examine infant food preparation practices at age 7, 9, 11, and 13 months overall and by sociodemographic characteristics. DesignData from a longitudinal study from the US Department of Agriculture's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Infant and Toddler Feeding Practices Study-2 (ITFPS-2) were used. ParticipantsA sample of 1,904 infants (970 males and 934 females) enrolled in WIC who had been introduced to solid foods and were consuming food prepared at home. Main Outcome MeasuresFood preparation practices included pureeing, mashing, chopping/dicing, and prechewing. Estimates were provided overall and by sociodemographics. AnalysisPrevalence estimates were calculated for each survey month overall and by sociodemographics. Chi-square tests for independence were used to test for differences. ResultsFood preparation practices changed as infants aged. Pureeing and mashing were common in month 7 (57.8% and 59.6%, respectively), but chopping/dicing were the most prevalent by month 13 (85.4%). Food preparation practices did not vary by education status, but statistical differences were consistently observed by race and ethnicity and inconsistently observed by maternal age at birth. Conclusions and ImplicationsExposing children to a range of food textures at an appropriate age is important for developmental progress. Continued culturally relevant efforts by WIC educators and health care providers can emphasize the importance of early experiences with food textures.

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.
