INTRODUCTION: Health equity science examines underlying social determinants, or drivers, of health inequities by building an evidence base to guide action across programs, public health surveillance, policy, and communications efforts. A Social Vulnerability Index (SVI) was utilized during the COVID-19 response to identify areas where inequities exist and support communities with vaccination. We set out to assess COVID-19 vaccination coverage by two SVI themes, Racial and Ethnicity Minority Status and Housing Type and Transportation to examine disparities. METHODS: US county-level COVID-19 vaccine administration data among persons aged 5 years and older reported to the Centers for Disease Control and Prevention from December 14, 2020 to December 14, 2022, were analyzed. Counties were categorized 1) into tertiles (low, moderate, high) according to each SVI theme's level of vulnerability or 2) dichotomized by urban or rural classification. Primary series vaccination coverage per age group were assessed for SVI social factors by SVI theme tertiles or urbanicity. RESULTS: Older adults aged 65 years and older had the highest vaccination coverage across all vulnerability factors compared with children aged 5-17 years and adults aged 18-64 years. Overall, children and adults had higher vaccination coverage in counties of high vulnerability. Greater vaccination coverage differences were observed by urbanicity as rural counties had some of the lowest vaccination coverage for children and adults. CONCLUSION: COVID-19 vaccination efforts narrowed gaps in coverage for adults aged 65 years and older but larger vaccination coverage differences remained among younger populations. Moreover, greater disparities in coverage existed in rural counties. Health equity science approaches to analyses should extend beyond identifying differences by basic demographics such as race and ethnicity and include factors that provide context (housing, transportation, age, and geography) to assist with prioritization of vaccination efforts where true disparities in vaccination coverage exist.

Objectives. To describe breastfeeding initiation and breastfeeding at 1, 2, and 3 months, and information sources on breastfeeding among women with a recent live birth by disability status. Methods. We analyzed October 2018 to December 2020 data from the Pregnancy Risk Assessment Monitoring System for 24 sites in the United States that included the Washington Group Short Set of Questions on Disability (seeing, hearing, walking or climbing stairs, remembering or concentrating, self-care, communicating). We defined disability as reporting "a lot of difficulty" or "cannot do this at all" on any of these questions. Results. Among 39 673 respondents, 6.0% reported disability. In adjusted analyses, breastfeeding was lower among respondents with disability at 2 (62.6% vs 66.6%; adjusted prevalence ratio [APR] = 0.94; 95% confidence interval [CI] = 0.89, 0.99) and 3 months (54.7% vs 59.6%; APR = 0.92; 95% CI = 0.86, 0.98) than those without disability. Respondents with disability were less likely to receive information from health care providers or support professionals (89.3% vs 92.3%), but as likely from breastfeeding or lactation specialists (78.1% vs 75.3%). Conclusions. Strategies to ensure women with disability, receive breastfeeding support, including breastfeeding information, could improve breastfeeding outcomes. (Am J Public Health. 2024;114(1):108-117. https://doi.org/10.2105/AJPH.2023.307438).

The objective of this study was to better understand US public awareness of maternal health benefits of breastfeeding. Data from the 2018 and 2021 SummerStyles surveys were analyzed to explore public belief in select maternal benefits of breastfeeding. As in 2018, in 2021 a low percentage of respondents believed that breastfeeding protects the mother against breast cancer (23.9%), high blood pressure (15.5%), or type 2 diabetes (15.4%), with male, older, and unmarried respondents less likely to believe in these protective effects. More public awareness of maternal benefits of breastfeeding might help increase demand for breastfeeding-supportive programs and policies.

INTRODUCTION: Initiation of breastfeeding has been associated with reduced post-perinatal infant mortality. Although most states have initiatives to protect, promote, and support breastfeeding, no analysis of the association of breastfeeding and infant mortality has been conducted at the state and regional level. To understand the associations between breastfeeding and post-perinatal infant mortality, the initiation of breastfeeding with post-perinatal infant mortality was analyzed by geographic region and individual states within each region. METHODS: This study was a prospective cohort analysis linking US national birth and post-perinatal infant death data for nearly 10 million infants born in 2016-2018, who were then followed for one year after birth and analyzed in 2021-2022. RESULTS: 9,711,567 live births and 20,632 post-perinatal infant deaths from 48 states and District of Columbia were included in the analysis. The overall adjusted odds ratio (AOR) and 95% confidence intervals (CI) for breastfeeding initiation with post-perinatal infant mortality was 0.67 (0.65-0.69, p<0.0001) for days 7-364. All 7 US geographic regions had significant reductions in post-perinatal infant deaths associated with breastfeeding initiation; Mid-Atlantic and Northeast regions had the largest reductions with AOR=0.56 (0.51-0.61, p<0.001; 0.50-0.63, p<0.001, respectively), while the Southeast had the smallest reduction with AOR=0.79 (0.75-0.84, p<0.001). Statistically significant results were noted for 35 individual states for reduction in total post-perinatal infant deaths. CONCLUSIONS: Although regional and state variation in the magnitude of the association of breastfeeding and infant mortality exists, the consistency of reduced risk, together with existing literature, suggests breastfeeding promotion and support may be a strategy to reduce infant mortality in the United States.

After reading the article by Hanna et al,1 we had concerns with their conclusions that do not seem to be supported by the data. This study included a sample of 11 lactating women with trace amounts of messenger RNA (mRNA) found in the breast milk of 5 women within 45 hours of monovalent mRNA COVID-19 vaccination. Based on these findings, the authors recommended caution regarding breastfeeding infants younger than 6 months within 48 hours of maternal vaccination and raised unfounded concerns about potential interference with routine infant vaccinations.

OBJECTIVE: Characterize feeding guidance mothers recall receiving from their child's health care provider (HCP). DESIGN: Cross-sectional study of mothers participating in the 2017-2019 National Survey of Family Growth. PARTICIPANTS: US mothers reporting (n = 1,302) information about their youngest child (aged 6 months to 5 years). VARIABLES MEASURED: Weighted percentage of mothers who recalled their child's HCP discussing 6 different feeding topics by demographic characteristics. ANALYSIS: Logistic regression assessing the relationship between recall of feeding guidance and demographics. RESULTS: In this sample, 36.9% of mothers (95% confidence interval, 32.3-41.4) recalled HCPs recommending solid food before 6 months old (34.6% at 4-5 months, and 2.3% before 4 months). Mothers who were older or had a higher education level were more likely than their counterparts to recall their HCP discussing several of the feeding topics examined. CONCLUSION AND IMPLICATIONS: Mothers reported high recollection of early childhood nutrition guidance from their HCP; however, certain topics (eg, appropriate timing of solid food introduction) could be prioritized, and some subpopulations may need additional focus to improve receipt of messages. A better understanding of variability in recall of feeding guidance could provide information for interventions to address barriers to receiving and retaining guidance.

The first 1000 days begins with pregnancy and ends at the child's second birthday. Nutrition throughout the life course, and especially during the first 1000 days, supports maternal health and optimal growth and development for children. We give a high-level summary of the state of nutrition in the first 1000 days in the United States. We provide examples where continued efforts are needed. We then discus select opportunities to strengthen federal research and surveillance, programs, and communication and dissemination efforts aimed at improving nutrition and positively, and equitably, influencing the health and well-being of mothers and children. (Am J Public Health. Published online ahead of print September 19, 2022::e1-e9. https://doi.org/10.2105/AJPH.2022.307028).

Approximately 50,000 infants are born in the United States each year with very low birthweight (VLBW) (<1,500 g).* Benefits of human milk to infants with VLBW include decreased risk for necrotizing enterocolitis, a serious illness resulting from inflammation and death of intestinal tissue that occurs most often in premature infants, especially those who are fed formula rather than human milk; late-onset sepsis; chronic lung disease; retinopathy of prematurity; and neurodevelopmental impairment (1). When mother's own milk is unavailable or insufficient, pasteurized donor human milk (donor milk) plus a multinutrient fortifier is the first recommended alternative for infants with VLBW (2). CDC's 2020 Maternity Practices in Infant Nutrition and Care (mPINC) survey was used to assess practices for donor milk use in U.S. advanced neonatal care units of hospitals that provide maternity care (3). Among 616 hospitals with neonatal intensive care units (level III or IV units),() 13.0% reported that donor milk was not available for infants with VLBW; however, approximately one half (54.7%) reported that most (80%) infants with VLBW do receive donor milk. Donor milk availability for infants with VLBW was more commonly reported among hospitals with a level IV unit, higher annual birth volume, location in the Midwest and Southwest regions, nonprofit and teaching status, and those designated Baby-Friendly.() Addressing hospitals' barriers to providing donor milk could help ensure that infants with VLBW receive donor milk when needed and help reduce morbidity and mortality in infants with VLBW (1,4).

BACKGROUND: Reducing infant mortality is a major public health goal. The potential impact of breastfeeding on infant deaths is not well studied in the United States (US). METHODS: We analyzed linked birth-death certificates for 3,230,500 US births that occurred in 2017, including 6,969 post-perinatal deaths from 7-364 days of age as the primary outcome, further specified as late-neonatal (7-27 days) or post-neonatal (28-364 days) deaths. The primary exposure was 'ever breastfed' obtained from birth certificates. Multiple logistic regression examined associations of ever breastfeeding with post-perinatal deaths and specific causes of deaths, controlling for maternal and infant factors. FINDINGS: We observed an adjusted reduced odds ratio (AOR)= 074 with 95% confidence intervals (CI)=070-079 for the association of breastfeeding initiation with overall infant deaths (7-364 days), AOR=060 (054-067) for late-neonatal deaths, and AOR=081 (076-087) for post-neonatal deaths. In race/ethnicity-stratified analysis, significant associations of breastfeeding initiation with reduced odds of overall infant deaths were observed for Hispanics [AOR=064 (055-074)], non-Hispanic Whites [AOR=075 (069-081)], non-Hispanic Blacks [AOR=083 (075-091)], and non-Hispanic Asians [AOR=051 (036-072)]. Across racial/ethnic groups, effect sizes for late-neonatal deaths were consistently larger than those for post-neonatal deaths. Significant effects of breastfeeding initiation were observed for deaths due to infection [AOR=081(069-094)], Sudden Unexpected Infant Death [AOR=085 (078-092)], and necrotizing enterocolitis [AOR=067 (049-090)]. INTERPRETATION: Breastfeeding initiation is significantly associated with reduced odds of post-perinatal infant deaths in multiple racial and ethnic groups within the US population. These findings support efforts to improve breastfeeding in infant mortality reduction initiatives.

BACKGROUND: 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). METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.

IMPORTANCE: Information on underlying conditions and severe COVID-19 illness among children is limited. OBJECTIVE: To examine the risk of severe COVID-19 illness among children associated with underlying medical conditions and medical complexity. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study included patients aged 18 years and younger with International Statistical Classification of Diseases, Tenth Revision, Clinical Modification code U07.1 (COVID-19) or B97.29 (other coronavirus) during an emergency department or inpatient encounter from March 2020 through January 2021. Data were collected from the Premier Healthcare Database Special COVID-19 Release, which included data from more than 800 US hospitals. Multivariable generalized linear models, controlling for patient and hospital characteristics, were used to estimate adjusted risk of severe COVID-19 illness associated with underlying medical conditions and medical complexity. EXPOSURES: Underlying medical conditions and medical complexity (ie, presence of complex or noncomplex chronic disease). MAIN OUTCOMES AND MEASURES: Hospitalization and severe illness when hospitalized (ie, combined outcome of intensive care unit admission, invasive mechanical ventilation, or death). RESULTS: Among 43 465 patients with COVID-19 aged 18 years or younger, the median (interquartile range) age was 12 (4-16) years, 22 943 (52.8%) were female patients, and 12 491 (28.7%) had underlying medical conditions. The most common diagnosed conditions were asthma (4416 [10.2%]), neurodevelopmental disorders (1690 [3.9%]), anxiety and fear-related disorders (1374 [3.2%]), depressive disorders (1209 [2.8%]), and obesity (1071 [2.5%]). The strongest risk factors for hospitalization were type 1 diabetes (adjusted risk ratio [aRR], 4.60; 95% CI, 3.91-5.42) and obesity (aRR, 3.07; 95% CI, 2.66-3.54), and the strongest risk factors for severe COVID-19 illness were type 1 diabetes (aRR, 2.38; 95% CI, 2.06-2.76) and cardiac and circulatory congenital anomalies (aRR, 1.72; 95% CI, 1.48-1.99). Prematurity was a risk factor for severe COVID-19 illness among children younger than 2 years (aRR, 1.83; 95% CI, 1.47-2.29). Chronic and complex chronic disease were risk factors for hospitalization, with aRRs of 2.91 (95% CI, 2.63-3.23) and 7.86 (95% CI, 6.91-8.95), respectively, as well as for severe COVID-19 illness, with aRRs of 1.95 (95% CI, 1.69-2.26) and 2.86 (95% CI, 2.47-3.32), respectively. CONCLUSIONS AND RELEVANCE: This cross-sectional study found a higher risk of severe COVID-19 illness among children with medical complexity and certain underlying conditions, such as type 1 diabetes, cardiac and circulatory congenital anomalies, and obesity. Health care practitioners could consider the potential need for close observation and cautious clinical management of children with these conditions and COVID-19.

Breastfeeding has health benefits for both infants and mothers and is recommended by numerous health and medical organizations*(,†) (1). The birth hospitalization is a critical period for establishing breastfeeding; however, some hospital practices, particularly related to mother-newborn contact, have given rise to concern about the potential for mother-to-newborn transmission of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19) (2). CDC conducted a COVID-19 survey (July 15-August 20, 2020) among 1,344 hospitals that completed the 2018 Maternity Practices in Infant Nutrition and Care (mPINC) survey to assess current practices and breastfeeding support while in the hospital. Among mothers with suspected or confirmed COVID-19, 14.0% of hospitals discouraged and 6.5% prohibited skin-to-skin care; 37.8% discouraged and 5.3% prohibited rooming-in; 20.1% discouraged direct breastfeeding but allowed it if the mother chose; and 12.7% did not support direct breastfeeding, but encouraged feeding of expressed breast milk. In response to the pandemic, 17.9% of hospitals reported reduced in-person lactation support, and 72.9% reported discharging mothers and their newborns <48 hours after birth. Some of the infection prevention and control (IPC) practices that hospitals were implementing conflicted with evidence-based care to support breastfeeding. Mothers who are separated from their newborn or not feeding directly at the breast might need additional postdischarge breastfeeding support. In addition, the American Academy of Pediatrics (AAP) recommends that newborns discharged before 48 hours receive prompt follow-up with a pediatric health care provider.

The Centers for Disease Control and Prevention administered the original Maternity Practices in Infant Nutrition and Care (mPINC) survey, a census of all US birth facilities, from 2007 to 2015 to monitor infant feeding-related maternity care practices and policies. The purpose of this paper is to describe the many uses of mPINC data. Hospitals, organizations and governments (federal, state and local) have used the mPINC survey as a tool for improving care among the populations they serve. Nationally, the mPINC survey has been used to document marked improvements in infant feeding-related maternity care. Researchers have used the mPINC data to examine a variety of questions related to maternity care practices and policies. The newly revised mPINC survey (2018) has been designed to capture changes that have occurred over the past decade in infant feeding-related US maternity care. Hospitals, organizations, governments and researchers will be able to continue using this important tool in their efforts to ensure US maternity care practices and policies are fully supportive of breastfeeding.

Prenatal breastfeeding intentions impact breastfeeding practices. Racial/ethnic disparities exist in breastfeeding rates; it is unknown if prenatal intentions and meeting intentions differ by race/ethnicity. A longitudinal cohort of USDA's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) which enrolled participants beginning in 2013 were used to estimate prenatal intentions for breastfeeding initiation, exclusive breast milk feeds at 1 and 3 months by race/ethnicity (n = 2070). Meeting intentions were determined by reported breast milk consumption at birth, 1 month and 3 months. Multivariable logistic regression was used to determine the association of race/ethnicity with meeting intentions. There were no differences in prenatal breastfeeding intentions between non-Hispanic White and non-Hispanic Black women (initiation: 86.9% and 87.2%; Month 1: 52.3% and 48.3%; Month 3: 43.8% and 40.9%; respectively), but a higher percentage of Hispanic women intended to breastfeed at all time points (95.5%, 68.3% and 56.4%; respectively, P < 0.05). Among women who intended to breastfeed at Month 1, non-Hispanic Black and Hispanic women had significantly lower odds of meeting intentions compared with non-Hispanic White women after adjusting for covariates (aORs: 0.63 [95% CI: 0.41, 0.98]; 0.64 [95% CI: 0.44, 0.92], respectively). Similar findings were seen for Month 3. Despite no differences in breastfeeding intentions, non-Hispanic Black women were less likely to meet their breastfeeding intentions than non-Hispanic White women. Hispanic women were more likely to intend to breastfeed yet were less likely to meet their intentions. This suggests that non-Hispanic Black and Hispanic women face challenges to meeting their longer breastfeeding intentions. Understanding how racism, bias and discrimination contribute to women not meeting their breastfeeding intentions may help efforts to reduce breastfeeding disparities.

Background: Breastfeeding is the preferred form of infant nutrition supporting optimal health of mothers and children. Research shows that medical training is deficient in preparing physicians to develop the knowledge base, clinical management skills, and attitudes to provide optimal support for breastfeeding families. We developed this project to assess the current gaps in breastfeeding education during medical training for physicians and to inform the plan to address those gaps. Materials and Methods: We conducted key informant interviews with nine professionals representing medical education, physician professional membership organizations, and ancillary stakeholders with an interest in improving physician education and training with respect to breastfeeding. Using those results, we developed and conducted a survey of physicians to identify training in breastfeeding received during medical school, residency/fellowship, and continuing medical education; confidence in managing breastfeeding; and attitudes about breastfeeding training. A total of 816 respondents completed the survey from the American Academy of Pediatrics, the American College of Obstetricians and Gynecologists, and the American Academy of Family Physicians. Results: Gaps exist in the training of physicians in terms of knowledge base, and clinical skills in breastfeeding support as highlighted through detailed key informant interviews and physician surveys. Physicians surveyed in the disciplines of pediatrics, obstetrics and gynecology, and family medicine indicated a desire to have more breastfeeding education integrated into their training, especially addressing clinical evaluation and management of breastfeeding problems. Conclusion: The landscape analysis demonstrates that medical education in breastfeeding remains inadequate despite previous efforts to address the gaps and that physicians desire more training in breastfeeding, especially clinical skills training, to improve provider confidence and competence. The analysis provides the foundation for further efforts to develop a comprehensive plan to enhance physician education in breastfeeding.

BACKGROUND: To describe the availability and nutrient composition of U.S. commercially available squeeze pouch infant and toddler foods in 2015. MATERIALS AND METHODS: Data were from information presented on nutrition labels for 703 ready-to-serve, pureed food products from 24 major U.S. infant and toddler food brands. We described nutritional components (e.g., calories, fat) and compared them between packaging types (squeeze pouch versus other packaging types) within food categories. RESULTS: 397 (56%) of the analyzed food products were packaged as squeeze pouches. Differences in 13 nutritional components between squeeze pouch versus other packaging types were generally small and varied by food category. Squeeze pouches in the fruits and vegetables, fruit-based, and vegetable-based categories were more likely to contain added sugars than other package types. CONCLUSION: In 2015, squeeze pouches were prevalent in the U.S. commercial infant and toddler food market. Nutrient composition differed between squeeze pouches and other packaging types for some macro- and micronutrients. Although it is recommended that infants and toddlers under two years old not consume any added sugars, a specific area of concern may be the inclusion of sources of added sugar in squeeze pouches. Linking this information with children's dietary intake would facilitate understanding how these differences affect overall diet quality.

Breast milk is the optimal source of infant nutrition. For the nearly one in 10 infants born prematurely in the United States annually (1), breast milk is especially beneficial, helping prevent sepsis and necrotizing enterocolitis and promoting neurologic development (2). National estimates of newborn feeding practices by gestational age have not been available previously. CDC analyzed 2017 birth certificate data from 48 states and the District of Columbia (3,194,873; 82.7% of all births) to describe receipt of breast milk among extremely preterm (20-27 weeks), early preterm (28-33 weeks), late preterm (34-36 weeks), and term (>/=37 weeks) infants with further stratification by maternal and infant characteristics. The prevalence of infants receiving any breast milk was 83.9% overall and varied by gestational age, with 71.3% of extremely preterm infants, 76.0% of early preterm infants, 77.3% of late preterm infants, and 84.6% of term infants receiving any breast milk. Disparities in receipt of breast milk by several sociodemographic factors, including maternal race/ethnicity, were noted across gestational age groups. These estimates suggest that many infants, particularly infants at high risk for medical complications, might not be receiving breast milk. Efforts are needed to increase the implementation of existing evidence-based policies and practices that support breast milk feeding, particularly for medically fragile infants (2,3).

With interest, we read the commentary by Pesch et al on the need for pediatricians to support their fellow breastfeeding colleagues.1 The American Academy of Pediatrics currently is funded by the Centers for Disease Control and Prevention to address improvements in breastfeeding-related physician education and training. As part of this project, the American Academy of Pediatrics, with input from representatives of the American College of Obstetrics and Gynecology, the American Academy of Family Physicians, and multiple other stakeholder organizations on the Project Advisory Committee developed the “Physician Education and Training on Breastfeeding Action Plan.”2 A key component of that plan is support for the breastfeeding physician. The plan included support for the revision of the Academy of Breastfeeding Medicine’s statement on breastfeeding-related educational objectives and skills needed for physicians, which includes a statement of support for breastfeeding medical students, residents, faculty, and staff.3 In addition, the American Academy of Family Physicians is leading efforts towards drafting a model policy describing how institutions can support their medical trainees (students, residents, and fellows). Finally, the Project Advisory Committee is in the process of developing a plan to create a culture of support for breastfeeding within the medical community that will emphasize support for breastfeeding physicians as a component of wellness. We agree with the authors’ conclusion that there is a need to support the breastfeeding physician. As the proportion of women physicians increases,4 with a majority being of reproductive age, creating environments that support breastfeeding physicians may help them meet their personal breastfeeding goals,5 improve their health and that of their own children,6, 7 and enhance their skills at providing breastfeeding care to their patients.5, 8 Breastfeeding physicians, as with all women who choose to breastfeed, need supportive environments to make breastfeeding a success.

BACKGROUND: Having a written breastfeeding policy that is routinely communicated to staff is important. Furthermore, hospitals seeking the Baby-Friendly designation are required to purchase infant formula at fair market value. We sought to determine the trends of model policies and receipt of free infant formula among hospitals with maternity care in the United States. METHODS: The Maternity Practices in Infant Nutrition and Care (mPINC) survey obtained information, every 2 years, on breastfeeding-related practices and policies from hospitals in the United States. We examined the prevalence of hospitals with a model breastfeeding policy, individual policy elements, and how policies were communicated as well as the receipt of free infant formula from 2009 to 2015. Statistical testing is not included because mPINC is a census. RESULTS: The proportion of hospitals with a model breastfeeding policy increased from 14.1% in 2009 to 33.1% in 2015. More hospitals incorporated policy elements on limited use of pacifiers (+21.0% points), early initiation of breastfeeding (+15.5% points), and limiting non-breast milk feeds of breastfed infants (+14.1% points). Fewer hospitals disseminated policies by word of mouth (-2.0% points), whereas, more posted policies (+8.1% points). The percent of hospitals not receiving free infant formula increased from 7.4% in 2009 to 28.7% in 2015. DISCUSSION: While more hospitals in the United States are implementing model breastfeeding policies and not receiving free infant formula, the majority do not adhere to these practices. Hospitals may consider reviewing their policies around infant feeding to improve care for new mothers.

BACKGROUND: Experiences during the birth hospitalization affect breastfeeding outcomes. In the United States, hospital policies and practices supportive of breastfeeding are routinely assessed through the Maternity Practices in Infant Nutrition and Care (mPINC) survey; however, mPINC does not capture data on breastfeeding outcomes. MATERIALS AND METHODS: Data from the 2015 mPINC survey were linked to 2015 data from the Joint Commission (TJC), a major accreditor of health care systems in the United States (n = 1,305 hospitals). Each hospital participating in mPINC is given a total score, which is the average of seven subscores; all ranging from 0 to 100. TJC has hospital-specific data on the percentage of infants exclusively breastfeeding at hospital discharge. We used linear regression to estimate differences between quartiles of (1) total mPINC score and (2) each mPINC subscore with rates of exclusive breastfeeding at hospital discharge, adjusting for hospital type, teaching status, and number of annual births. We additionally used linear models to test for trend across quartiles of mPINC score. RESULTS: The mean percentage of in-hospital exclusive breastfeeding increased from 39.0% for hospitals in the lowest mPINC total score quartile (<75) to 60.4% for hospitals in the highest mPINC total score quartile (>/=89), an adjusted difference of 21.1 percentage points (95% confidence interval 18.6-23.6). The mean percentage of in-hospital exclusive breastfeeding significantly increased (p < 0.0001) as mPINC scores increased for total mPINC score and for each mPINC subscore. CONCLUSIONS: Higher mPINC scores were associated with higher rates of in-hospital exclusive breastfeeding. Hospitals can make improvements to their maternity care practices and policies to support breastfeeding.

BACKGROUND: About 15% of women aged 15-44 in the US experience infertility. Factors associated with infertility and fertility treatments may also be associated with lactation difficulties. Limited data exist examining the impact of infertility or mode of conception on breastfeeding outcomes. OBJECTIVE: The objectives of this study were to report breastfeeding outcomes (initiation and duration at 8 weeks) among women who conceived spontaneously compared to women who conceived using fertility treatments (assisted reproductive technology, intrauterine insemination, or fertility-enhancing drugs). STUDY DESIGN: Maternal-reported data from four states from the 2012-2015 Pregnancy Risk Assessment and Monitoring System (PRAMS) were used to explore use of fertility treatment and breastfeeding initiation and continuation at 8 weeks (n=15,615). Data were weighted to represent all women delivering live births within each state; SAS survey procedures were used to account for PRAMS complex survey design. Stepwise, multivariable logistic regression, adjusted for maternal demographics, parity, plurality, mode of delivery, preterm birth, and maternal pre-pregnancy health conditions, was used to quantify the associations between fertility treatment use and breastfeeding. RESULTS: Mode of conception was not associated with breastfeeding outcomes when comparing women who conceived spontaneously to women who conceived using any fertility treatment. The odds of breastfeeding at 8 weeks were lower among women who conceived using assisted reproductive technology, after adjusting for basic demographic covariates (aOR: 0.71; 95% CI: 0.52-0.97) and additionally adjusting for maternal health conditions (aOR: 0.68; 95% CI: 0.49-0.93), but this difference was no longer significant after adjusting for plurality and preterm birth (aOR: 0.74; 95% CI: 0.54-1.02). CONCLUSIONS: This study suggests that mothers who conceive using assisted reproductive technology may breastfeed for shorter durations than mothers who conceive spontaneously, partially mediated by an increased likelihood of multiples and infants born preterm. Studies are needed to elucidate these associations and to understand the intentions and barriers to breastfeeding among women who conceive with the help of assisted reproductive technology.

BACKGROUND: Hospitals that provide maternity care can play an important role in providing or directing mothers to postdischarge breastfeeding support, which improves breastfeeding duration especially when providing multiple support modes. This study described 2007-2015 national trends in postdischarge breastfeeding supports among United States maternity care hospitals. METHODS: Data were from the Maternity Practices in Infant Nutrition and Care survey, a biennial census of maternity care hospitals in the United States and territories. Hospitals reported whether they provided nine support types, which we categorized into three support modes: physical contact (eg, return visits), active reaching out (eg, telephone calls), and referrals (eg, to lactation consultants). We calculated prevalence of each support type, each support mode, and providing all three support modes for each survey year and examined trends over 2007-2015. For 2015, we assessed differences by hospital- and area-level characteristics. RESULTS: Prevalence of providing all three support modes increased from 24% (2007) to 31% (2015). Nearly all (99%) hospitals provided referrals in each survey year. Fewer offered physical contact and active reaching out. However, from 2007 to 2015, the prevalence of physical contact increased from 39% to 46%; active reaching out increased from 54% to 64%. In 2015, smaller and rural hospitals were more likely to provide all three discharge supports. CONCLUSIONS: Prevalence of offering referrals was high, but there is room for improvement in providing physical contact and active reaching out to ensure multiple modes of support are available to help mothers reach their breastfeeding goals.

BACKGROUND: Rooming-in, or keeping mothers and infants together throughout the birth hospitalization, increases breastfeeding initiation and duration, and is one of the Ten Steps to Successful Breastfeeding. METHODS: The Centers for Disease Control and Prevention's (CDC) Maternity Practices in Infant Nutrition and Care (mPINC) survey is a biennial census of all birth facilities in the United States and its territories. Data from the 2007-2015 mPINC surveys were used to assess trends in the prevalence of hospitals with most (>/=90%) infants rooming-in more than 23 hours per day (ideal practice). Hospital practices among breastfed infants not rooming-in at night and reasons why hospitals without ideal rooming-in practices removed healthy, full-term, breastfed infants from their mothers' rooms were also analyzed. RESULTS: The percentage of hospitals with ideal practice increased from 27.8% in 2007 to 51.4% in 2015. Most breastfed infants who were not rooming-in were brought to their mothers at night for feedings (91.8% in 2015). Among hospitals without ideal rooming-in practices, the percentage removing 50% or more of infants from their mothers' rooms at any point during the hospitalization decreased for all reasons surveyed during 2007-2015; however, in 2015, hospitals still reported regularly removing infants for hearing tests (73.2%), heel sticks (65.5%), infant baths (40.2%), pediatric rounds (35.5%), and infant photos (25.4%). CONCLUSIONS: Hospital implementation of rooming-in increased 23.6 percentage points during 2007-2015. Continued efforts are needed to ensure that all mothers who choose to breastfeed receive optimal lactation support during the first days after giving birth.

BACKGROUND: Evidence-based maternity practices and policies can improve breastfeeding duration and exclusivity. Maternity facilities report practices through the Maternity Practices in Infant Nutrition and Care (mPINC) survey, but individual outcomes, such as breastfeeding duration and exclusivity, are not collected. METHODS: mPINC data on maternity care practices for 2009 were linked to data from the 2009 Pregnancy Risk Assessment Monitoring System (PRAMS), which collects information on mothers' behaviors and experiences around pregnancy. We calculated total mPINC scores (range 0-100). PRAMS data on any and exclusive breastfeeding at 8 weeks were examined by total mPINC score quartile. RESULTS: Of 15 715 women in our sample, 53.7% were breastfeeding any at 8 weeks, and 29.3% were breastfeeding exclusively. They gave birth at 1016 facilities that had a mean total mPINC score of 65/100 (range 19-99). Care dimension subscores ranged from 41 for facility discharge care to 81 for breastfeeding assistance. In multivariable analysis adjusting for covariates, a positive relationship was found between total mPINC score quartile and both any breastfeeding (quartile 2: odds ratio [OR] 1.40 [95% confidence interval {CI} 1.08-1.83], quartile 3: OR 1.50 [95% CI 1.15-1.96], quartile 4: OR 2.12 [95% CI 1.61-2.78] vs quartile 1) and exclusive breastfeeding (quartile 3: OR 1.41 [95% CI 1.04-1.90], quartile 4: OR 1.89 [95% CI 1.41-2.55] vs quartile 1) at 8 weeks. CONCLUSIONS: These data demonstrate that evidence-based maternity care practices and policies are associated with better breastfeeding outcomes. Maternity facilities may evaluate their practices and policies to ensure they are helping mothers achieve their breastfeeding goals.

Breast milk is the recommended nutrition for infants. For preterm infants, when mother's milk is not available, pasteurized donor milk is recommended (1). Non-Hispanic black mothers are at increased risk for having a preterm birth and for not breastfeeding (2,3); however, it is not known whether demographic disparities exist in the use of breast milk in neonatal intensive care units (NICUs). Data from CDC's 2015 Maternity Practices in Infant Nutrition and Care (mPINC) survey, which does not collect patient-level demographics, were linked to the 2011-2015 U.S. Census Bureau's American Community Survey (ACS)* to examine use of breast milk in NICUs based on demographic makeup of the hospital's postal code area. Among U.S. hospitals with a NICU, the use of mother's own milk and donor milk were examined by the percentage of non-Hispanic black (black) residents in the hospital postal code area, categorized as being above or below the national average (12.3%). In postal codes with >12.3% black residents, 48.9% of hospitals reported using mothers' own milk in ≥75% of infants in the NICU, and 38.0% reported not using donor milk, compared with 63.8% and 29.6% of hospitals, respectively, in postal codes with ≤12.3% black residents. Further investigation is needed to understand variations in breast milk use in NICUs. Targeted efforts to increase breast milk use in hospitals located in postal codes where the percentage of black mothers is above the national average might help ensure more equitable access to breast milk for preterm and other high-risk infants.

BACKGROUND: Although previous studies suggest that the intentions of mothers to breastfeed during pregnancy strongly predict actual breastfeeding practice, no studies have examined the changes in the intentions of mothers to breastfeed from the prenatal to neonatal periods. The purpose of this study was to examine changes in intended breastfeeding duration from the prenatal to neonatal periods, their association with actual duration, and predictors for shortened duration. METHODS: The Infant Feeding Practices Study II was a longitudinal study of mothers in the United States. Changes to intended breastfeeding duration were calculated as the difference from prenatal to neonatal reports (months); we compared this change to actual breastfeeding duration. By using multivariable logistic regression, we identified maternal characteristics associated with a shortened breastfeeding intention. RESULTS: Of 1780 women, 43.7% had no change to intended breastfeeding duration, 35.0% had a shorter intended duration, and 21.3% had a longer intended duration. Mothers with shortened intended duration also had shorter actual duration (P < .001). Women of Hispanic ethnicity, with a prepregnancy body mass index of ≥30 kg/m2 , who were primiparous and who smoked prenatally had increased odds of shortening their breastfeeding intention from prenatal to neonatal reports. A maternal age of ≥35 years was associated with decreased odds of shortened breastfeeding intention. CONCLUSION: Approximately one in three women shorten their intended breastfeeding duration during the early postpartum period, which negatively affects the actual duration of their breastfeeding. Women may need additional support during the early postpartum period to meet their prenatal breastfeeding intentions.

BACKGROUND: Exclusive breastfeeding is recommended for the first 6 months of life. However, many barriers to breastfeeding exist. We examine public opinions about the benefits of breastfeeding and the infant health risks associated with formula feeding. METHODS: A national public opinion survey was conducted in 2013. Participants indicated their level of agreement with four breastfeeding-related statements. Except for the last one, all statements were positively worded with agreement representing positive opinions toward breastfeeding. To focus on the prevalence of positive opinions, we estimated percentage agreement with the first three statements, but disagreement with the fourth. Multiple logistic regression was used to examine how odds of these positive opinions varied by socio-demographic factors. RESULTS: Seventy-eight percent of participants agreed that breastmilk is nutritionally designed for infants, but few believed breastfeeding protects against overweight (12%). Approximately one-quarter agreed that formula feeding increases the chance of illness, whereas 45 percent disagreed that infant formula is equivalent to breastmilk. Older, less-educated, unmarried, and non-Hispanic black participants were less likely to agree that formula feeding increases the risk of infant illness. Races other than non-Hispanic white, participants aged 30-44 years and 45-59 years, unmarried, and less-educated participants were less likely to disagree with the equivalence of infant formula to breastmilk. DISCUSSION: The nutritional value of breastmilk is well known. Fewer adults believe that breastfeeding protects against childhood overweight or that formula feeding increases the chance of infant illness. Communication efforts may increase public awareness of the health benefits of breastfeeding.

Introduction Breastfed newborns are often given non-breast milk supplements in the hospital, which can negatively impact breastfeeding outcomes. Efforts to improve maternity care practices include reducing supplementation of breastfed newborns. Methods The Maternity Practices in Infant Nutrition and Care (mPINC) survey is administered every 2 years to all hospitals in the United States and territories with registered maternity beds. We examined provision of non-breast milk supplements to healthy, full-term breastfed newborns from 2009 to 2013. Results Hospitals that provided non-breast milk supplements to at least 50 % of breastfed newborns decreased from 31.5 % in 2009 to 23.3 % in 2013. Among hospitals providing any supplements, there was no change in the percent that supplemented with infant formula; whereas, supplementing with water declined from 8.8 % in 2009 to 4.2 % in 2013 and with glucose water from 23.4 % to 12.5 %, respectively. In 2013, 64.9 % of breastfed infants were supplemented with formula for "mother's choice," 25.0 % for "doctor's orders," and 8.7 % for "nurse's recommendation." Discussion Despite improvements in maternity care practices, nearly one-fourth of hospitals are still providing at least 50 % of healthy, full-term breastfed newborns with non-breast milk supplements. While there has been no change in the proportion of hospitals providing infant formula supplements, the proportion supplementing with water and glucose water have declined. Additional education and support of mothers during the early post-partum period and training of physicians may address reasons breastfed infants are supplemented.

Researchers hypothesize that pregnancy and lactation are part of a continuum, with lactation meant to "reset" the adverse metabolic profile that develops as a part of normal pregnancy, and that when lactation does not occur, women maintain an elevated risk of cardio-metabolic diseases. Several large prospective and retrospective studies, mostly from the United States and other industrialized countries, have examined the associations between lactation and cardio-metabolic outcomes. Less evidence exists regarding an association of lactation with maternal postpartum weight status and dyslipidemia, whereas more evidence exists for an association with diabetes, hypertension, and subclinical and clinical cardiovascular disease. Expected final online publication date for the Annual Review of Nutrition Volume 36 is July 17, 2016. Please see http://www.annualreviews.org/catalog/pubdates.aspx for revised estimates.

Zika virus is a mosquito-borne flavivirus discovered in Africa in 1947. Most persons with Zika virus infection are asymptomatic; symptoms when present are generally mild and include fever, maculopapular rash, arthralgia, and conjunctivitis. Since early 2015, Zika virus has spread rapidly through the Americas, with local transmission identified in 31 countries and territories as of February 29, 2016, including several US territories. All age groups are susceptible to Zika virus infection, including children. Maternal-fetal transmission of Zika virus has been documented; evidence suggests that congenital Zika virus infection is associated with microcephaly and other adverse pregnancy and infant outcomes. Perinatal transmission has been reported in 2 cases; 1 was asymptomatic, and the other had thrombocytopenia and a rash. Based on limited information, Zika virus infection in children is mild, similar to that in adults. The long-term sequelae of congenital, perinatal, and pediatric Zika virus infection are largely unknown. No vaccine to prevent Zika virus infection is available, and treatment is supportive. The primary means of preventing Zika virus infection is prevention of mosquito bites in areas with local Zika virus transmission. Given the possibility of limited local transmission of Zika virus in the continental United States and frequent travel from affected countries to the United States, US pediatric health care providers need to be familiar with Zika virus infection. This article reviews the Zika virus, its epidemiologic characteristics, clinical presentation, laboratory testing, treatment, and prevention to assist providers in the evaluation and management of children with possible Zika virus infection.
