Early childhood WIC participation, cognitive development and academic achievement

The role of SNAP and WIC in the bidirectional relationship between food insecurity and maternal depressive symptoms

BACKGROUND

The association between food insecurity and maternal depressive symptoms has been established by many cross-sectional and longitudinal studies however the understanding of the reciprocal relationship between them remains unclear. Further, previous research demonstrates that federal nutrition assistance decreases food insecurity and promotes maternal mental well-being but further research is needed to elucidate the moderating role of these programs in the association between food insecurity and maternal depressive symptoms. Therefore, the current study examined the bidirectional associations between maternal depression probability and food insecurity using cross-lagged models and then tested the main and moderating effects of SNAP and WIC.

METHODS

Data were from the Future of Families and Child Wellbeing Study and the sample included 1948 mothers who participated in year 3 and year 5 of data collection.

RESULTS

The cross-lagged paths show that food insecurity at year 3 predicted maternal depression probability at year 5 and depression probability at year 3 predicted food insecurity at year 5. There was a significant moderating effect of WIC receipt on the association between food insecurity at year 3 and at year 5 such that when mothers with high food insecurity at year 3 received WIC, they were less food insecure at year 5.

LIMITATIONS

The study oversampled for unmarried mothers only two waves of data were used for the cross-lagged panel models.

CONCLUSIONS

Results demonstrate the need to incorporate mental health services with the existing food assistance programs and the need to destigmatize the application process and program structure.

Distilling the Fundamentals of Evidence-Based Public Health Policy

Public health policy interventions are associated with many important public health achievements. To provide public health practitioners and decision makers with practical approaches for examining and employing evidence-based public health (EBPH) policy interventions, we describe the characteristics and benefits that distinguish EBPH policy interventions from programmatic interventions. These characteristics include focusing on health at a population level, focusing on upstream drivers of health, and involving less individual action than programmatic interventions. The benefits of EBPH policy interventions include more sustained effects on health than many programs and an enhanced ability to address health inequities. Early childhood education and universal preschool provide a case example that illustrates the distinction between EBPH policy and programmatic interventions. This review serves as the foundation for 3 concepts that support the effective use of public health policy interventions: applying core component thinking to understand the population health effects of EBPH policy interventions; understanding the influence of existing policies, policy supports, and the context in which a particular policy is implemented on the effectiveness of that policy; and employing a systems thinking approach to identify leverage points where policy implementation can have a meaningful effect.

Reducing WIC Administrative Burdens to Promote Health Equity

This Viewpoint discusses barriers to Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participation for low-income and racial and ethnic minoritized families and outlines strategies that health care professionals and health systems can use to help families overcome these barriers.

Cost-effectiveness of Improved WIC Food Package for Preventing Childhood Obesity

BACKGROUND AND OBJECTIVES

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) prevents food insecurity and supports nutrition for more than 3 million low-income young children. Our objectives were to determine the cost-effectiveness of changes to WIC's nutrition standards in 2009 for preventing obesity and to estimate impacts on socioeconomic and racial/ethnic inequities.

METHODS

We conducted a cost-effectiveness analysis to estimate impacts from 2010 through 2019 of the 2009 WIC food package change on obesity risk for children aged 2 to 4 years participating in WIC. Microsimulation models estimated the cases of obesity prevented in 2019 and costs per quality-adjusted-life year gained.

RESULTS

An estimated 14.0 million 2- to 4-year old US children (95% uncertainty interval (UI), 13.7-14.2 million) were reached by the updated WIC nutrition standards from 2010 through 2019. In 2019, an estimated 62 700 (95% UI, 53 900-71 100) cases of childhood obesity were prevented, entirely among children from households with low incomes, leading to improved health equity. The update was estimated to cost $10 600 per quality-adjusted-life year gained (95% UI, $9760-$11 700). If WIC had reached all eligible children, more than twice as many cases of childhood obesity would have been prevented.

CONCLUSIONS

Updates to WIC's nutrition standards for young children in 2009 were estimated to be highly cost-effective for preventing childhood obesity and contributed to reducing socioeconomic and racial/ethnic inequities in obesity prevalence. Improving nutrition policies for young children can be a sound public health investment; future research should explore how to improve access to them.

Understanding the Predictors of Low Take-Up of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC): A Nationwide Longitudinal Study

INTRODUCTION

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is among the largest U.S. social safety net programs. Although strong evidence exists regarding the benefits of WIC, take-up (i.e., participation among eligible individuals) has steadily declined in the past decade. This study addresses gaps in our knowledge regarding predictors of WIC take-up during this time.

METHODS

Data were drawn from the 1998-2017 waves of the National Health Interview Study (NHIS), a serial cross-sectional study of the U.S.

POPULATION

The analytic sample included 23,645 children and 10,297 women eligible for WIC based on self-reported demographic characteristics. To investigate predictors of WIC take-up, we regressed self-reported WIC receipt on a range of individual-level predictors (e.g., age, nativity, income) and state- level predictors (e.g., unemployment rate, governor's political affiliation) using multivariable logistic regression. In secondary analyses, results were additionally stratified by race/ethnicity, time period, and age (for children).

RESULTS

For both women and children, older maternal age and higher educational attainment were associated with decreased take-up of WIC. Associations differed by race/ethnicity, time period, and state characteristics including caseload of other social programs (e.g., Medicaid).

DISCUSSION

Our study identifies groups that are less likely to take up WIC benefits for which they are eligible, thereby contributing important evidence to inform programs and policies to increase WIC participation among groups with lower take-up. As WIC evolves past the COVID-19 pandemic, special attention will be needed to ensure that resources to encourage and support the participation of racially and economically marginalized individuals are equitably distributed.

Women, Infants, and Children enrollment and pregnancy-related behaviors and outcomes among Medicaid recipients in the United States

BACKGROUND

Nearly 40% of pregnant women in 2016 were enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Prior studies have investigated nutritional behaviors among WIC participants and access to WIC breastfeeding counseling services. However, there are no (few?) nationally representative, large-scale analyses of WIC users and pregnancy behaviors. Thus, the present study aims to examine associations between WIC use and select pregnancy outcomes among Medicaid enrollees.

METHODS

We examined pregnancy-related behaviors and outcomes using 2018 U.S. Birth Certificates for Medicaid patients aged 18-45 years (N = 1 159 263). Outcomes included prenatal care (PNC) adequacy, breastfeeding initiation, cigarette use, and gestational weight gain. Standard binary and multinomial logistic regressions were used to estimate odds ratios (OR) and 95% confidence intervals (CIs).

RESULTS

After adjustment, WIC users had statistically significant increased odds of adequate PNC (adjusted OR [AOR] = 1.31 [95% CI 1.30, 1.32]), cigarette use (quit smoking during pregnancy 1.09 [1.07, 1.11]; smoked throughout pregnancy 1.16 [1.14, 1.18], and exceeding recommendations of weight gain 1.07 [1.06, 1.08]) compared with non-WIC users. WIC enrollees also experienced decreased odds of breastfeeding initiation (0.85 [0.85, 0.86]) compared with non-WIC users.

CONCLUSIONS

The study underscores the value of the WIC program in improving access to PNC. Yet, low-income women remain at risk for smoking during pregnancy and exceeding the recommended amount of weight gain. Breastfeeding initiation is lower than anticipated among WIC participants. Additional studies are needed to investigate WIC program efficacy.

Social Spending and Educational Gaps in Infant Health in the United States, 1998-2017

Recent expansions of child tax, food assistance, and health insurance programs have made American families' need for a robust social safety net highly evident, while researchers and policymakers continue to debate the best way to support families via the welfare state. How much do children-and which children-benefit from social spending? Using the State-by-State Spending on Kids Dataset, linked to National Vital Statistics System birth data from 1998 to 2017, we examine how state-level child spending affects infant health across maternal education groups. We find that social spending has benefits for both low birth weight and preterm birth rates, especially among babies born to mothers with less than a high school education. The stronger benefits of social spending among lower educated families lead to meaningful declines in educational gaps in infant health as social spending increases. Our findings are consistent with the idea that a strong local welfare state benefits infant health and increases equality of opportunity, and that spending on nonhealth programs is equally beneficial for infant health as investments in health programs.

WIC Participants’ Perceptions of the Cash-Value Benefit Increase during the COVID-19 Pandemic

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

Building a framework to understand and address vulnerability to reading difficulties among children in schools in the United States

This paper presents a vulnerability framework as a means to contextualize inequities in reading achievement among children who are vulnerable to poor reading outcomes. Models to understand vulnerability have been applied in the social sciences and public health to identify population disparities and design interventions to improve outcomes. Vulnerability is multifaceted and governed by context. Using a vulnerability framework for the science of reading provides an innovative approach for acknowledging multilevel factors contributing to disparities. The ecological considerations of both individual differences in learners and conditions within and outside of schools ensures that scientific advances are realized for learners who are more vulnerable to experiencing reading difficulty in school.

Special supplemental nutrition programme for women, infants and children participation and unmet health care needs among young children

BACKGROUND

Research shows that the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) programme improves the nutrition and health of low-income families. Recent studies have also shown that WIC improves access to health care services and use. However, no studies have reported whether WIC reduces unmet health care needs in young children.

METHODS

This is a retrospective study of 2810 mostly low-income urban mothers and their five-year-old children in the Fragile Families and Child Wellbeing Study. Mothers reported whether they received any WIC benefits since the child turned three. Unmet health care needs were operationalized through three outcomes: not having a place for routine care, not having seen a doctor for a regular checkup in the past year, and never having had a dental checkup.

RESULTS

In adjusted logistic regressions, children in families receiving WIC benefits were less likely to not have a place for routine care (odds ratio = 0.54, 95% CI: 0.32, 0.93), and less likely to never have had a dental check-up (odds ratio = 0.75, 95% CI: 0.58-0.97). There was no association between receiving WIC benefits and the child not having a regular checkup in the past year.

CONCLUSIONS

In this study of urban children, receiving WIC benefits was associated with a lower risk of unmet health care needs. Given that only half of eligible families receive WIC benefits, the programme has the potential to reduce unmet health care needs for a large number of children of eligible families not enrolled in the programme.

Food insecurity and cardiovascular disease: Current trends and future directions

Food insecurity (FI) - a state of limited access to nutritionally adequate food - is notably more prominent among patients with cardiovascular disease (CVD) than the general population. Current research suggests that FI increases the risk of cardiovascular morbidity and mortality through various behavioral and biological pathways. Importantly, FI is more prevalent among low-income households and disproportionately affects households with children, particularly those led by single mothers. These disparities necessitate solutions specifically geared towards helping these high-risk subgroups, who also experience increased risk of CVD associated with FI. Further, individuals with CVD may experience increased risk of FI due to the financial burden imposed by CVD care. While participation in federal aid programs like the Supplemental Nutrition Assistance Program and the Special Supplemental Nutrition Program for Women, Infants, and Children has been associated with cardiovascular health benefits, residual FI and lower dietary quality among many families suggest a need for better outreach and expanded public assistance programs. Healthcare systems and community organizations can play a vital role in screening individuals for FI and connecting them with food and educational resources. While further research is needed to evaluate sociodemographic differences in the FI-CVD relationship, interventions at the policy, health system, and community levels can help address both the burden of FI and its impacts on cardiovascular health.

Public Investments and Class Gaps in Parents' Developmental Expenditures

Families and governments are the primary sources of investment in children, providing access to basic resources and other developmental opportunities. Recent research identifies significant class gaps in parental investments that contribute to high levels of inequality by family income and education. State-level public investments in children and families have the potential to reduce class inequality in children's developmental environments by affecting parents' behavior. Using newly assembled administrative data from 1998-2014, linked to household-level data from the Consumer Expenditure Survey, we examine how public sector investment in income support, health and education is associated with the private expenditures of low and high-SES parents on developmental items for children. Are class gaps in parental investments in children narrower in contexts of higher public investment for children and families? We find that more generous public spending for children and families is associated with significantly narrower class gaps in private parental investments. Moreover, we find that equalization is driven by bottom up increases in low-SES households' developmental spending in response to the progressive state investments of income support and health, and by top down decreases in high-SES households' developmental spending in response to the universal state investment of public education.

Caregiver Perspectives on Underutilization of WIC: A Qualitative Study

OBJECTIVES

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a federal program that improves the health of low-income women (pregnant and postpartum) and children up to 5 years of age in the United States. However, participation is suboptimal. We explored reasons for incomplete redemption of benefits and early dropout from WIC.

METHODS

In 2020-2021, we conducted semistructured interviews to explore factors that influenced WIC program utilization among current WIC caregivers (n = 20) and caregivers choosing to leave while still eligible (n = 17) in Massachusetts. By using a deductive analytic approach, we developed a codebook grounded in the Consolidated Framework for Implementation Research.

RESULTS

Themes across both current and early-leaving participants included positive feelings about social support from the WIC clinic staff and savings offered through the food package. Participants described reduced satisfaction related to insufficient funds for fruits and vegetables, food benefits inflexibility, concerns about in-clinic health tests, and in-store item mislabeling. Participants described how electronic benefit transfer cards and smartphone apps eased the use of benefits and reduced stigma during shopping. Some participants attributed leaving early to a belief that they were taking benefits from others.

CONCLUSIONS

Current and early-leaving participants shared positive WIC experiences, but barriers to full participation exist. Food package modification may lead to improved redemption and retention, including increasing the cash value benefit for fruits and vegetables and diversifying food options. Research is needed regarding the misperception that participation means "taking" benefits away from someone else in need.

A Review of Interventions to Increase WIC Enrollment and Participation

Our goal was to identify strategies aimed at increasing Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) enrollment and participation rates. The WIC program provides many health benefits for pregnant women, mothers, and children. WIC offers nutrition education, formula, fruits and vegetables, and other food to pregnant and postpartum women and their children until they reach the age of five. Despite the availability of this program nationwide, enrollment and participation rates remain low across the country. Several states have tried various interventions to combat this deficiency of engagement with the goal of increasing WIC enrollment and participation. We conducted a scoping review to identify articles based on pre-specified inclusion and exclusion criteria. Two reviewers independently identified and screened articles. Subsequently, three reviewers independently extracted study details and outcomes related to WIC enrollment and participation rate changes. We included 14 studies reporting on 12 interventions from 3945 citations reviewed. Seven of these were published papers, while the others were final reports of USDA WIC Special Grant Projects. All the observed interventions had some success increasing WIC participation. Virtual interventions demonstrated the most success based on preliminary evidence. Successful interventions showed percentage gains in enrollment close to 8% and changes in participation over 9%. Overall, the literature surrounding WIC enrollment interventions reveal a mixed impact on improving participation. Many successful interventions involve an online or virtual engagement component which can provide educational resources on WIC benefits, nutrition, and living a healthy lifestyle.

"It Was Actually Pretty Easy": COVID-19 Compliance Cost Reductions in the WIC Program

In recent years, scholars have examined the barriers to accessing public assistance benefits. Research identifies learning, compliance, and psychological costs as deterring program use. Compliance costs reflect the burdens of following program rules, which may entail providing documentation, responding to discretionary demands of bureaucrats, or attending appointments to maintain benefits. Studies identify one element of compliance costs-quarterly appointments-as a barrier to continued WIC participation. This article draws on 44 in-depth qualitative interviews with participants in the Special Supplemental Nutrition Assistance Program for Women, Infants, and Children (WIC). We examine how WIC participants perceive the reduction of compliance costs following the implementation of remote appointments in response to the COVID-19 pandemic. WIC participants report satisfaction with remote appointments and a reduction in the compliance costs of accessing and maintaining benefits. We conclude by recommending longer term changes to policy and practices to increase access and continuity in WIC receipt.

A scoping review of research on policies to address child undernutrition in the Millennium Development Goals era

OBJECTIVE

The breadth of research on the impact of nutrition-specific policies to address child undernutrition is not well documented. This review maps the evidence base and identifies gaps on such policies.

DESIGN

We systematically searched Medline, Embase, PAIS Index for public policy, Scopus and Web of Science databases to identify eligible studies. Key study characteristics, including research design, type of policy, time span of policy before impact assessment, child age at outcome assessment and types of outcomes assessed, were abstracted in duplicate.

SETTING

Low-, middle- and high-income countries.

PARTICIPANTS

Studies were eligible for inclusion if they aimed to assess the impact of population-level nutrition-specific policies on undernutrition among children under 10 years of age.

RESULTS

Of the 5646 abstracts screened, eighty-three studies were included. A range of policies to address child undernutrition were evaluated; the majority were related to micronutrient fortification. Most studies were observational, reported on mandatory regional or sub-national polices, were conducted in high-income countries and evaluated policies within 1 year of implementation. A narrow set of health outcomes were evaluated, most commonly iodine deficiency disorders and neural tube defects.

CONCLUSIONS

Nutrition policies were commonly associated with improved child nutritional status and health. However, this evidence is primarily based on limited settings and on a limited number of outcomes. Further research is needed to assess the longer-term impact of a broader range of nutrition policies on child health, particularly in low- and middle-income countries.

Experiences of Hispanic Families with Social Services in the Racially Segregated Southeast: Views from Administrators and Workers in North Carolina

North Carolina-as a state in the racially segregated Southeast-offers a unique context to understand access to social services for Hispanic families and children. Theories of administrative burden posit that Hispanic families likely face high learning, compliance, and psychological costs. Hispanic families face challenges that compound these costs: limited English language and literacy proficiency, complex household composition, and citizenship status of family members and other household members. With new survey results and qualitative data on social service administrators and front-line workers, we examine how these costs may affect access to programs for Hispanic families who reside in a state with a history of racial divisions that have shaped local policy implementation. Some workers noted transportation barriers and complex application processes as limiting access. While we expected to find that Hispanic families may be disadvantaged by decentralized service delivery in a manner that is similar to the experiences of African American families, workers instead note significant resources that help facilitate Hispanic families' access to programs. Workers view national anti-immigrant policies and rhetoric, rather than state and local policy rules or resource constraints, as limiting their capacity to serve Hispanic families.

The Revised WIC Food Package and Child Development: A Quasi-Experimental Study

BACKGROUND AND OBJECTIVES

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), one of the largest US safety net programs, was revised in 2009 to be more congruent with dietary guidelines. We hypothesize that this revision led to improvements in child development.

METHODS

Data were drawn from a cohort of women and children enrolled in the Conditions Affecting Neurocognitive Development and Learning in Early Childhood study from 2006 to 2011 (Shelby County, TN; N = 1222). Using quasi-experimental difference-in-differences analysis, we compared measures of growth, cognitive, and socioemotional development between WIC recipients and nonrecipients before and after the policy revision.

RESULTS

The revised WIC food package led to increased length-for-age z scores at 12 months among infants whose mothers received the revised food package during pregnancy (β = .33, 95% confidence interval: 0.05 to 0.61) and improved Bayley Scales of Infant Development cognitive composite scores at 24 months (β = 4.34, 95% confidence interval: 1.11 to 7.57). We observed no effects on growth at age 24 months or age 4 to 6 years or cognitive development at age 4 to 6 years.

CONCLUSIONS

This study provides some of the first evidence that children of mothers who received the revised WIC food package during pregnancy had improved developmental outcomes in the first 2 years of life. These findings highlight the value of WIC in improving early developmental outcomes among vulnerable children. The need to implement and expand policies supporting the health of marginalized groups has never been more salient, particularly given the nation's rising economic and social disparities.

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.

Higher Utilization of Social Services Is Associated with Higher Language Scores in Children from Deeply Impoverished Urban Families

Language development has been consistently linked with socioeconomic status (SES), with children from lower SES backgrounds at higher risk for language delays. The objective of this study is to investigate the relationship between familial social service use and language development during the first year of life. Thirty-one low-income mothers and their infants were recruited from the New York metropolitan area. Mothers provided information about demographics and utilization of social services (Women, Infants, and Children (WIC), food stamps, Medicaid, and public housing). Infant language skills were assessed using the Preschool Language Scale. Multiple linear regressions were used to investigate the relationship between social service use and language skills. We found that the number of social services utilized was not an overall significant linear predictor of language skills. However, social service use interacted with poverty level to predict language skills. Specifically, for families living in deep poverty, higher service use significantly predicted higher infant language scores (β = 3.4, p = 0.005). These results suggest that social services may be an appropriate target to help narrow socioeconomic disparities in language development.

A Spatial Evaluation of Healthy Food Access: Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Participants

CONTEXT

It is well known in public health practice that vulnerable populations in rural and inner-city areas may not be able to access healthy foods due to cost, availability, access to transport, and other factors.

PROGRAM

The Inter Tribal Council of Arizona, Inc (ITCA), Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides moderate- and lower-income families with increased access to nutritional information, health care, and healthy foods.

IMPLEMENTATION

ITCA WIC authorizes and enters into contracts with stores that carry a baseline of healthy foods. To use WIC benefits, participants must go to authorized WIC stores where approved healthy foods are available.

EVALUATION

ITCA Tribal Epidemiology Center developed a methodological framework using Geographic Information Systems to examine WIC authorized stores in 2014 and 2016 to determine whether there were gaps in the store network. To be considered served by the store network, urban WIC participants were required to be within 1 mile and nonurban WIC participants were required to be within 5 miles of a store. We examined whether additional stores could be added to the network to decrease travel distance and travel time in order to further improve access to healthy foods.

DISCUSSION

Between 2014 and 2016, 700 stores were examined and WIC authorized 8 new stores to increase the network; all remote and most rural stores were WIC authorized. In 2014, about 50% of participants met the criteria to be considered served. In 2016, 54% met the criteria, indicating a modest increase in store access for WIC participants. Store network access increased in urban areas from 39% to 41% and from 66% to 74% in nonurban areas between 2014 and 2016. By evaluating the ITCA WIC authorized stores, we note that ITCA increased access to WIC approved healthy foods for WIC participants.

Detecting the Effects of Early-Life Exposures: Why Fecundity Matters

Prenatal exposures have meaningful effects on health across the lifecourse. Innovations in causal inference have shed new light on these effects. Here, we motivate the importance of innovation in the characterization of fecundity, and prenatal selection in particular. We argue that such innovation is crucial for expanding knowledge of the fetal origins of later life health. Pregnancy loss is common, responsive to environmental factors, and closely related to maternal and fetal health outcomes. As a result, selection into live birth is driven by many of the same exposures that shape the health trajectories of survivors. Lifecourse effects that are inferred without accounting for these dynamics may be significantly distorted by survival bias. We use a set of Monte Carlo simulations with realistic parameters to examine the implications of prenatal survival bias. We find that even in conservatively specified scenarios, true fetal origin effects can be underestimated by 50% or more. In contrast, effects of exposures that reduce the probability of prenatal survival but improve the health of survivors will be overestimated. The absolute magnitude of survival bias can even exceed small effect sizes, resulting in inferences that beneficial exposures are harmful or vice-versa. We also find reason for concern that moderately sized true effects, underestimated due to failure to account for selective survival, are missing from scientific knowledge because they do not clear statistical significance filters. This bias has potential real-world costs; policy decisions about interventions to improve maternal and infant health will be affected by underestimated program impact.

The Impact of the Revised WIC Food Package on Maternal Nutrition During Pregnancy and Postpartum

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides nutritional support for pregnant and postpartum women and young children. The typical food package provided to recipient families was revised in October 2009 to include more whole grains, fruits, vegetables, and low-fat milk. Little is known about whether these revisions improved nutrition among women during this critical period of the life course. We conducted a quasiexperimental difference-in-differences analysis, comparing WIC recipients ("treatment" group) before and after the WIC policy change, while accounting for temporal trends among nonrecipients ("control" group). We examined nutritional outcomes among a cohort of 1,454 women recruited during pregnancy in 2006-2011 in Memphis and surrounding Shelby County, Tennessee. We found improvements in several measures of dietary quality and nutrient intake during pregnancy, although these did not persist into the postpartum period. Results were robust to numerous sensitivity analyses. At a time when federal WIC funding is threatened, this study provides some of the first evidence of the benefits of recent WIC revisions among low-income women.

WIC Participation and Breastfeeding after the 2009 WIC Revision: A Propensity Score Approach

In this study, we examined the association between participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and breastfeeding outcomes before and after the 2009 revisions. Four-thousand-three-hundred-and-eight WIC-eligible children younger than 60 months were included from the 2005–2014 National Health and Nutrition Examination Survey (NHANES). We compared two birth cohorts with regard to their associations between WIC participation and being ever-breastfed and breastfed at 6 months. We estimated the average effect of the treatment for the treated to assess the causal effect of WIC participation on breastfeeding based on propensity score matching. The results showed that WIC-eligible participating children born between 2000 and 2008 were significantly less likely than WIC-eligible nonparticipating children to ever receive breastfeeding (p < 0.05) or to be breastfed at 6 months (p < 0.05). Among children born between 2009 and 2014, WIC-eligible participating children were no longer less likely to ever receive breastfeeding compared to WIC-eligible nonparticipating children; the gap remained in breastfeeding at 6-months (p < 0.05). The disparities in prevalence of ever breastfed between WIC-eligible participants and nonparticipants have been eliminated since the 2009 WIC revision. More efforts are needed to improve breastfeeding persistence among WIC-participating mother–infant dyads.

Recovery From Malnutrition Among Refugee Children Following Participation in the Special Supplemental Nutrition for Women, Infants, and Children (WIC) Program in Massachusetts, 1998-2010

OBJECTIVES

(1) To examine patterns of catch-up growth and anemia correction in refugee children younger than 5 years after participation in the Special Supplemental Nutrition for Women, Infants, and Children (WIC) program, and (2) to identify factors associated with recovery from growth abnormalities.

DESIGN

Records on 1731 refugee children younger than 5 years who arrived in Massachusetts between 1998-2010 were matched to WIC program records and then restricted to 779 children who had at least 2 WIC visits. Kaplan-Meier curves and Cox proportional hazards models were used to examine how sex affected time to recovery from malnutrition and anemia. Factors associated with recovery were analyzed in SAS using multivariate logistic regression.

SETTING

Massachusetts.

PARTICIPANTS

Refugee children younger than 5 years on arrival, who visited a WIC program at least twice between 1998 and 2010.

MAIN OUTCOME MEASURES

(1) Proportion of children who recovered from low height-for-age (stunting), low weight-for-age, low weight-for-height (wasting), and anemia; (2) odds ratios for factors associated with recovery; and (3) Kaplan-Meier curves showing recovery over time from low height-for-age, low weight-for-age, and low weight-for-height.

RESULTS

The number of WIC visits was associated with recovery from stunting, wasting, low weight-for-age, and anemia; results reached statistical significance for stunting (odds ratio [OR] = 8.64; 95% confidence interval [CI], 2.25-33.19), low weight-for-age (OR = 5.28; 95% CI, 1.35-20.73), and anemia (OR = 6.50; 95% CI, 2.69-15.69). Female sex was associated with recovery from stunting, wasting, and low weight-for-age, whereas male sex was associated with recovery from anemia; the associations were statistically significant between female sex and stunting (OR = 9.14; 95% CI, 1.93-43.29), wasting (OR = 14.78; 95% CI, 1.57-138.85), and low weight-for-age (OR = 4.29; 95% CI, 1.09-16.79).

CONCLUSIONS

Children who remained engaged in WIC may recover better from malnutrition than children with fewer WIC visits, although there are limitations to the available data.These findings suggest that those working with refugee families should prioritize outreach toward initiating and maintaining WIC program enrollment for eligible refugee children.

Society of Behavioral Medicine (SBM) position statement: SBM urges Congress to preserve and increase the financing of federally funded nutrition assistance programs and services

Deep cuts have been proposed to federally funded nutrition assistance programs, including the Supplemental Nutrition Assistance Program (SNAP); the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC); and federally subsidized school breakfast and lunch programs. Yet, these programs help parents afford healthy meals for their families, pregnant and postpartum mothers access supplemental foods and health services for themselves and their infants and young children, and children obtain the nutrition necessary for optimal school performance. Participation in these programs is linked with reductions in perinatal morbidity and mortality, improved childhood growth trajectories, enhanced school performance, and reductions in food insecurity and poverty. Given these compelling health and economic benefits, the Society of Behavioral Medicine urges Congress to protect and increase funding for federally funded nutrition assistance programs, specifically SNAP, WIC, and school breakfast and lunch programs. Per the recent (2017) recommendations of the School Nutrition Association, Congress should also resist any attempts to "block-grant" subsidized school breakfast and lunch programs, which could reduce access to these programs. It is further recommended that Congress improve the scope of implementation- and outcomes-based assessments of these programs. Finally, we recommend efforts to increase awareness of and participation in SNAP, WIC, and federally funded school meal programs for eligible individuals, children, and families.

Community participation factors and poor neurocognitive functioning among persons with schizophrenia

Poor neurocognitive functioning among individuals with schizophrenia is typically conceptualized as resulting from a disease process. The objective of this article is to further expand understanding of poor neurocognition beyond pathogenesis toward a perspective that also incorporates community participation factors. This article focuses on three such factors-sedentary behavior, loneliness, and poverty-that have been demonstrated to be related to neurocognition and are highly prevalent among individuals with schizophrenia. This article provides an overview of the research on each factor and discusses its possible connection to neurocognitive challenges for individuals with schizophrenia. Implications for research, policy, and practice efforts are then proposed to broaden approaches to understanding and addressing neurocognitive challenges in this population.

Targeted Estimation of the Relationship Between Childhood Adversity and Fluid Intelligence in a US Population Sample of Adolescents

Many studies have shown inverse associations between childhood adversity and intelligence, although most are based on small clinical samples and fail to account for the effects of multiple co-occurring adversities. Using data from the 2001-2004 National Comorbidity Survey Adolescent Supplement, a cross-sectional US population study of adolescents aged 13-18 years (n = 10,073), we examined the associations between 11 childhood adversities and intelligence, using targeted maximum likelihood estimation. Targeted maximum likelihood estimation incorporates machine learning to identify the relationships between exposures and outcomes without overfitting, including interactions and nonlinearity. The nonverbal score from the Kaufman Brief Intelligence Test was used as a standardized measure of fluid reasoning. Childhood adversities were grouped into deprivation and threat types based on recent conceptual models. Adjusted marginal mean differences compared the mean intelligence score if all adolescents experienced each adversity to the mean in the absence of the adversity. The largest associations were observed for deprivation-type experiences, including poverty and low parental education, which were related to reduced intelligence. Although lower in magnitude, threat events related to intelligence included physical abuse and witnessing domestic violence. Violence prevention and poverty-reduction measures would likely improve childhood cognitive outcomes.

The Impact of WIC on Infant Immunizations and Health Care Utilization

OBJECTIVE

To test how prenatal participation in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) impacts health care utilization and immunizations within the first year of an infant's life.

DATA SOURCE

We utilize comprehensive South Carolina Medicaid claims data from 2004 to 2013 linked with birth certificates data from 2004 to 2012. These data contain information on WIC participation and all health care utilization within the first year of an infant's life.

STUDY DESIGN

We employ a maternal fixed-effects empirical design to control for unobserved factors that influence WIC participation and health care utilization.

PRINCIPAL FINDINGS

We estimate that WIC participation increases infant health care utilization within the first year of life by 0.20 well-child visits (95 percent CI 0.16-0.23), by 0.22 vaccinations (95 percent CI 0.17-0.27), and by increasing the probability of receiving care in an emergency room by 2.9 percentage points (95 percent CI 2.0-3.8). Additionally, our results show that WIC participation decreases the average number of days an infant spends in the hospital within his or her first year of life by 0.41 days (95 percent CI 0.22-0.60).

CONCLUSIONS

These findings suggest that WIC may increase health care costs in some dimensions while reducing it in others, and more work is needed to fully evaluate the impact of the program on future expenditures.

Responsibility in the age of Developmental Origins of Health and Disease (DOHaD) and epigenetics

Insights from the Developmental Origins of Health and Disease paradigm and epigenetics are elucidating the biological pathways through which social and environmental signals affect human health. These insights prompt a serious debate about how the structure of society affects health and what the responsibility of society is to counteract health inequalities. Unfortunately, oversimplified interpretations of insights from Developmental Origins of Health and Disease and epigenetics may be (mis)used to focus on the importance of individual responsibility for health rather than the social responsibility for health. In order to advance the debate on responsibility for health, we present an ethical framework to determine the social responsibility to counteract health inequalities. This is particularly important in a time where individual responsibility often justifies a passive response from policymakers.

Receipt of public assistance during childhood and hypertension risk in adulthood

PURPOSE

We examined if receipt of public assistance during childhood lowered risk for hypertension by mid-life in a cohort of African Americans in the Southeastern United States.

METHODS

We used multiple logistic regression models to assess the relationship between receipt of public assistance during childhood and adult hypertension among 405 male and 737 female adult participants enrolled between 1988 and 2001 in the Pitt County Study, a community-based prospective cohort study of African Americans in North Carolina. Statistical analyses were adjusted for child and adult sociodemographic measures as well as adult psychosocial and lifestyle factors.

RESULTS

Women who grew up in economically disadvantaged families and who received public assistance during childhood had a 66% decreased odds of hypertension by mid-life compared with women similarly disadvantaged in childhood but who did not receive public assistance, odds ratio = 0.34; 95% confidence interval: 0.14-0.83. No association was observed for African American men.

CONCLUSIONS

Receipt of anti-poverty federal assistance during childhood was associated with reduced risk for hypertension by mid-life among African American women. It is possible that social expenditures on public assistance programs for families in need could produce long-term health benefits for children.

Child access to the nutritional safety net during and after the Great Recession: The case of WIC

Because children disproportionately live in poverty, they are especially vulnerable during economic crises, making the social safety net a key buffer against the effects of economic disadvantage on their development. The Great Recession of 2007-2009 had strong and lasting effects on American children and families, including striking negative effects on their health environments. Understanding access to the health safety net during this time of increased economic need, as well as the extent to which all children-regardless of age, income or race/ethnicity-share in the increased use of transfer programs, is therefore important in identifying the availability and accessibility of government assistance for those in need. Focusing on the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) program because of its strong effects on child development, we use longitudinal data from the Survey of Income and Program Participation (SIPP) to examine change and stability in children's WIC enrollment before, during and after the recession. Specifically, we examine: 1) whether children's WIC enrollment increased alongside changing family income, and 2) the extent to which changes in participation were shared by all subpopulations, regardless of age, income, and race/ethnicity. Analyses reveal that WIC participation among eligible children increased leading up to, during, and after the Great Recession, suggesting that the program was responsive to increasing economic need. Examining the distribution of WIC enrollment across demographic groups largely reveals a pattern of stable inequality in access and "take up." Children born to poorer and less-educated mothers were more likely to be enrolled prior to the recession, and these differences remain mostly constant during and after the recession. Eligible Hispanic children had consistently higher enrollment, particularly among those in families with foreign-born mothers. The findings suggest that not all eligible children equally enroll in WIC, but that these differences have not been drastically exacerbated by macroeconomic instability.

Participation in the special supplemental nutrition program for women, infants, and children is not associated with early childhood socioemotional development: Results from a longitudinal cohort study

Socioemotional development in early childhood has long-term impacts on health status and social outcomes, and racial and socioeconomic disparities in socioemotional skills emerge early in life. The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is an early childhood nutrition intervention with the potential to ameliorate these disparities. Our objective was to assess the impact of WIC on early socioemotional development in a longitudinal study. We examined the association between WIC participation and scores on the Brief Infant Toddler Social Emotional Assessment (BITSEA) in 327 predominantly African American mother–child dyads who were participants in the longitudinal Conditions Affecting Neurocognitive Development in Early Life (CANDLE) Study (Memphis, TN). To account for selection bias, we used within-child fixed effects to model the variability in each child's BITSEA scores over two measurement occasions (ages 12 and 24 months). Final models were adjusted for time-varying characteristics including child age, maternal stress, mental health, child abuse potential, marital status, and food stamp participation. In fully adjusted models, we found no statistically significant effect of WIC on change in socioemotional development (β = 0.22 [SD = 0.39] and β = − 0.58 [SD = 0.79] for BITSEA Competence and Problem subdomains, respectively). Using rigorous methods and a longitudinal study design, we found no significant association between WIC and socioemotional development in a high needs population. This finding suggests that early childhood interventions that more specifically target socioemotional development are necessary if we are to reduce racial disparities in socioemotional skills and prevent poor social and health outcomes across the life course.

•

The effect of WIC on early childhood socioemotional development is largely unknown.

•

We study this association in a well-characterized, longitudinal cohort of mother–child dyads.

•

We adjust for stable characteristics with fixed effects and add covariates.

•

We find no association between WIC and childhood socioemotional development.

Predictors of Poor School Readiness in Children Without Developmental Delay at Age 2

BACKGROUND AND OBJECTIVES

Current recommendations emphasize developmental screening and surveillance to identify developmental delays (DDs) for referral to early intervention (EI) services. Many young children without DDs, however, are at high risk for poor developmental and behavioral outcomes by school entry but are ineligible for EI. We developed models for 2-year-olds without DD that predict, at kindergarten entry, poor academic performance and high problem behaviors.

METHODS

Data from the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B), were used for this study. The analytic sample excluded children likely eligible for EI because of DDs or very low birth weight. Dependent variables included low academic scores and high problem behaviors at the kindergarten wave. Regression models were developed by using candidate predictors feasibly obtainable during typical 2-year well-child visits. Models were cross-validated internally on randomly selected subsamples.

RESULTS

Approximately 24% of all 2-year-old children were ineligible for EI at 2 years of age but still had poor academic or behavioral outcomes at school entry. Prediction models each contain 9 variables, almost entirely parental, social, or economic. Four variables were associated with both academic and behavioral risk: parental education below bachelor's degree, little/no shared reading at home, food insecurity, and fair/poor parental health. Areas under the receiver-operating characteristic curve were 0.76 for academic risk and 0.71 for behavioral risk. Adding the mental scale score from the Bayley Short Form-Research Edition did not improve areas under the receiver-operating characteristic curve for either model.

CONCLUSIONS

Among children ineligible for EI services, a small set of clinically available variables at age 2 years predicted academic and behavioral outcomes at school entry.

Effects of early intervention on dietary intake and its mediating role on cognitive functioning: a randomised controlled trial

OBJECTIVE

To investigate the impact of an early intervention programme, Preparing for Life, on dietary intake between 12 and 36 months of age, and the mediating role played by diet on cognitive functioning.

DESIGN

A randomised controlled trial evaluation of a community-based home visiting programme. The intervention involved biweekly visits from mentors from pregnancy until age 5 years and parent training at age 2 years. Dietary intake was assessed at 12, 18, 24 and 36 months using an FFQ to calculate the proportion meeting dietary recommendations. Cognitive functioning was measured at 24 and 36 months. Treatment effects were estimated using conventional χ 2 tests, permutation testing, inverse probability weighting and the stepdown procedure. Mediation analysis examined the indirect effect of the intervention on cognitive functioning via its effect on dietary intake.

SETTING

Socio-economically disadvantaged communities in Dublin, Republic of Ireland.

SUBJECTS

Pregnant women (n 233) were assigned to the intervention (n 115) or control (n 118) group using an unconditional probability randomisation strategy.

RESULTS

Positive treatment effects were observed for meeting dietary recommendations for protein foods at 24 (OR=2·52) and 36 (OR=2·42) months, and all food groups at 24 (OR=3·92) months. There were no effects on grain, dairy, fruit and vegetable, or fatty/sugary food recommendations in most models. The conventional and more novel methods yielded similar results. Mediation analysis indicated that 13 % of the intervention's effect on cognitive functioning was mediated by 36-month protein food consumption.

CONCLUSIONS

The study demonstrates some potential to alter early childhood dietary patterns through community-based intervention programmes.

Poverty and Child Health in the United States

Almost half of young children in the United States live in poverty or near poverty. The American Academy of Pediatrics is committed to reducing and ultimately eliminating child poverty in the United States. Poverty and related social determinants of health can lead to adverse health outcomes in childhood and across the life course, negatively affecting physical health, socioemotional development, and educational achievement. The American Academy of Pediatrics advocates for programs and policies that have been shown to improve the quality of life and health outcomes for children and families living in poverty. With an awareness and understanding of the effects of poverty on children, pediatricians and other pediatric health practitioners in a family-centered medical home can assess the financial stability of families, link families to resources, and coordinate care with community partners. Further research, advocacy, and continuing education will improve the ability of pediatricians to address the social determinants of health when caring for children who live in poverty. Accompanying this policy statement is a technical report that describes current knowledge on child poverty and the mechanisms by which poverty influences the health and well-being of children.

A Road Map to Address the Social Determinants of Health Through Community Collaboration

Economic, environmental, and psychosocial needs are common and wide-ranging among families cared for in primary care settings. Still, pediatric care delivery models are not set up to systematically address these fundamental risks to health. We offer a roadmap to help structure primary care approaches to these needs through the development of comprehensive and effective collaborations between the primary care setting and community partners. We use Maslow's Hierarchy of Needs as a well-recognized conceptual model to organize, prioritize, and determine appropriate interventions that can be adapted to both small and large practices. Specifically, collaborations with community organizations expert in addressing issues commonly encountered in primary care centers can be designed and executed in a phased manner: (1) build the case for action through a family-centered risk assessment, (2) organize and prioritize risks and interventions, (3) develop and sustain interventions, and (4) operationalize interventions in the clinical setting. This phased approach to collaboration also includes shared vision, codeveloped plans for implementation and evaluation, resource alignment, joint reflection and adaptation, and shared decisions regarding next steps. Training, electronic health record integration, refinement by using quality improvement methods, and innovative use of clinical space are important components that may be useful in a variety of clinical settings. Successful examples highlight how clinical-community partnerships can help to systematically address a hierarchy of needs for children and families. Pediatricians and community partners can collaborate to improve the well-being of at-risk children by leveraging their respective strengths and shared vision for healthy families.

A Primary Care-Based Early Childhood Nutrition Intervention: Evaluation of a Pilot Program Serving Low-Income Hispanic Women

Nutrition in early childhood can significantly impact physical and mental health outcomes for children. However, research on broadly defined pre/postnatal nutrition interventions is sparse. The present study is a process and outcome evaluation of a primary care-based nutrition intervention targeting low-income Hispanic women. Pregnant women enrolled in the program were in their first trimester and received services through their 6-month well child check. The program provided vouchers for fruits and vegetables from the local farmers' market, nutrition classes, cooking classes, and lactation counseling. We conducted a prospective study of program participants (n = 32) and a comparable group of women for whom the program was not available (n = 29). Panel survey data measured maternal diet, exercise, stress, depression, social support, infant feeding practices, and demographics. Outcome measures obtained from medical records included pregnancy weight gain, infant weight at 6 and 12 months, and infant development at 9 months. Findings reveal that the program was not associated with infant weights. However, despite similar profiles at baseline, women in the intervention group were more likely than women in the comparison group to have significant improvements in diet, exercise, and depression (p ≤ .05). In addition, participants were more likely to breastfeed (p = .07) and their infants were more likely to pass the ages and stages developmental screen (p = .06) than women in the comparison group. The study was limited by a lack of random assignment and small samples. However, the breadth and size of the effects suggest pre/postnatal nutrition interventions integrated into primary care warrant additional investigation.
