A substantial proportion of US maternity care facilities engage in practices that are not evidence-based and that interfere with breastfeeding. The CDC Survey of Maternity Practices in Infant Nutrition and Care (mPINC) showed significant variation in maternity practices among US states.

The purpose of this article is to use benchmarking techniques to identify states within relevant peer groups that were top performers on mPINC survey indicators related to breastfeeding support.

We used 11 indicators of breastfeeding-related maternity care from the 2011 mPINC survey and benchmarking techniques to organize and compare hospital-based maternity practices across the 50 states and Washington, DC. We created peer categories for benchmarking first by region (grouping states by West, Midwest, South, and Northeast) and then by size (grouping states by the number of maternity facilities and dividing each region into approximately equal halves based on the number of facilities).

Thirty-four states had scores high enough to serve as benchmarks, and 32 states had scores low enough to reflect the lowest score gap from the benchmark on at least 1 indicator. No state served as the benchmark on more than 5 indicators and no state was furthest from the benchmark on more than 7 indicators. The small peer group benchmarks in the South, West, and Midwest were better than the large peer group benchmarks on 91%, 82%, and 36% of the indicators, respectively. In the West large, the Midwest large, the Midwest small, and the South large peer groups, 4-6 benchmarks showed that less than 50% of hospitals have ideal practice in all states.

The evaluation presents benchmarks for peer group state comparisons that provide potential and feasible targets for improvement.

Given the importance of mother’s milk for very low birth weight (VLBW) infants, it would be helpful to know which circumstances are most favorable for milk expression.

This study aimed to estimate the volume of milk obtained by mothers of VLBW infants as a function of proximity to the infant and use of the kangaroo position during the actual expression.

In this prospective cohort study, when the infant was stable and the mother had established a breastfeeding routine, she was given a notebook in which to record the location of expression and the amount of milk expressed for 10 consecutive days. Breast milk expression volumes were recorded and analyzed.

Data were collected on 26 mother-VLBW infant dyads and 1642 milk expressions. The first early morning expressions (n = 276, 17%) were conducted at home. Thereafter, 743 (45%) expressions were conducted far from the infant, either in a different room within the hospital or at home, and 623 (38%) were performed in proximity to the infant (beside the incubator, during kangaroo mother care [KMC], after KMC, or during kangaroo father care). The mean milk volume was significantly higher when expression was conducted in proximity to the infant. When only milk expressions conducted in proximity to the infant were considered, volumes obtained during KMC (107.7 mL, 91.8-123.5) and after KMC (117.7 mL, 99.0-136.5) were significantly higher than those obtained beside the incubator (96.9 mL, 79.9-113.9), respectively, P = .0030 and P = .0024.

Milk expression conducted in proximity to the infant, particularly during and immediately after KMC, is associated with higher milk volume.

The Human Milk Banking Association of North America (HMBANA) is a nonprofit association that standardizes and facilitates the establishment and operation of donor human milk (DHM) banks in North America. Each HMBANA milk bank in the network collects data on the DHM it receives and distributes, but a centralized data repository does not yet exist. In 2010, the Food and Drug Administration recognized the need to collect and disseminate systematic, standardized DHM bank data and suggested that HMBANA develop a DHM data repository.

This study aimed to describe data currently collected by HMBANA DHM banks and evaluate feasibility and interest in participating in a centralized data repository.

We conducted phone interviews with individuals in different HMBANA milk banks and summarized descriptive statistics.

Eight of 13 (61.5%) sites consented to participate. All respondents collected donor demographics, and half (50%; n = 4) rescreened donors after 6 months of continued donation. The definition of preterm milk varied between DHM banks (≤ 32 to ≤ 40 weeks). The specific computer program used to house the data also differed. Half (50%; n = 4) indicated that they would consider participation in a centralized repository.

Without standardized data across all HMBANA sites, the creation of a centralized data repository is not yet feasible. Lack of standardization and transparency may deter implementation of donor milk programs in the neonatal intensive care unit setting and hinder benchmarking, research, and quality improvement initiatives.

Human milk oligosaccharides (HMO) represent the third most abundant component of human breast milk. More than a hundred structurally distinct HMO have been identified, and the HMO composition varies between mothers as well as over the course of lactation. Some newborn infants receive donor milk (DM) when their mother’s own milk (MOM) volume is inadequate or unavailable.

This study aimed to compare HMO content between DM and MOM.

We used high performance liquid chromatography analysis of fluorescently labeled HMO to analyze the variation in HMO amount and composition of 31 different batches of DM (each pooled from 3 individual donors) provided by the Mothers’ Milk Bank in San Jose, California, and compared it to 26 different MOM samples donated by mothers with infants in our neonatal intensive care unit (NICU).

Total HMO amount as well as concentrations of lacto-N-tetraose, lacto-N-neotetraose, lacto-N-fucopentaose 1, and disialyllacto-N-tetraose were significantly lower in DM than in MOM, whereas the concentrations of 3’-sialyllactose and 3-fucosyllactose were significantly higher in DM.

Our data show that infants in our NICU who receive DM are likely to ingest HMO at different total amounts and relative composition from what they would receive with their MOM. Recent in vitro and animal studies have started to link individual HMO to infant health and disease. Future studies are needed to assess the importance of a mother-infant match with regard to HMO composition.

Benefits of using a breast pump are well documented, but pump-related problems and injuries and the associated risk factors have not been reported.

This study aimed to describe breast pump-related problems and injuries and identify factors associated with these problems and injuries.

Data were from the Infant Feeding Practices Study II; mothers were recruited from a nationally distributed consumer opinion panel. Mothers were asked about breast pump use, problems, and injuries at infant ages 2, 5, and 7 months. Survival analysis was used to identify factors associated with pump-related problems and injuries.

The sample included 1844 mothers. About 62% and 15% of mothers reported pump-related problems and injuries, respectively. The most commonly reported problem was that the pump did not extract enough milk and the most commonly reported injury was sore nipples. Using a battery-operated pump and intending to breastfeed less than 12 months were associated with higher risks of pump-related problems and injury. Learning from a friend to use the pump was associated with lower risk of pump-related problems, and using a manual pump and renting a pump were associated with a higher risk of problems.

Our results suggest that problems and injuries associated with breast pump use can happen to mothers of all socioeconomic characteristics. Breastfeeding mothers may reduce their risks of problems and injury by not using battery-operated pumps and may reduce breast pump problems by not using manual pumps and by learning breast pump skills from a person rather than following written or video instructions.

Distribution of industry-sponsored formula sample packs to new mothers undermines breastfeeding.

Using data from the Infant Feeding Practices Study II (IFPS II), we aimed to determine whether receipt of 4 different types of bags was associated with exclusive breastfeeding during the first 6 months of life.

We extracted data from IFPS II questionnaires. Type of discharge bag received was categorized as “formula bag,” “coupon bag,” “breastfeeding supplies bag,” or “no bag”. We examined exclusive breastfeeding status at 10 weeks (post hoc) and at 6 months using univariate descriptive analyses and multivariate logistic regression models, controlling for sociodemographic and attitudinal variables.

Overall, 1868 (81.4%) of women received formula bags, 96 (4.2%) received coupon bags, 46 (2.0%) received breastfeeding supplies bags, and 284 (12.4%) received no bag. By 10 weeks, recipients of breastfeeding supplies bags or no bag were significantly more likely to be exclusively breastfeeding than formula bag recipients. In the adjusted model, compared to formula bag/coupon bag recipients, recipients of breastfeeding supplies bag/no bag were significantly more likely to breastfeed exclusively for 6 months (odds ratio = 1.58; 95% confidence interval, 1.06-2.36).

The vast majority of new mothers received formula sample packs at discharge, and this was associated with reduced exclusive breastfeeding at 10 weeks and 6 months. Bags containing breastfeeding supplies or no bag at all were positively associated with exclusive breastfeeding at 10 weeks and 6 months.

Exclusive breastfeeding is recommended for 6 months. Successful breastfeeding requires support from family members, peers, and health care professionals.

This study aimed to determine the association between maternal perception of the attitudes of obstetric and pediatric care providers about infant feeding during the neonatal period and exclusive breastfeeding at 1, 3, and 6 months.

The study sample consisted of 1602 women from the Infant Feeding Practices Study II (2005-2007), a longitudinal study of women in the United States. Analyses included chi-square and Fisher’s exact tests and logistic regression models.

Mothers who perceived that the obstetric care provider favored exclusive breastfeeding were significantly more likely to exclusively breastfeed their infants at 1 and 3 months (odds ratio [OR] = 1.73, 95% confidence interval [CI], 1.33-2.24; and OR = 1.41, 95% CI, 1.09-1.80, respectively) as compared to mothers who perceived that the obstetric care provider was neutral about the type of infant feeding. Similarly, mothers who perceived that the pediatric care provider favored exclusive breastfeeding had higher odds of exclusively breastfeeding their infants at 1 and 3 months (OR = 1.53, 95% CI, 1.17-1.99; and OR = 1.51, 95% CI, 1.17-1.95, respectively) as compared to mothers who perceived that the pediatric care provider was neutral about the type of infant feeding. The association was no longer significant at 6 months.

Maternal perception of obstetric and pediatric care providers’ preference for exclusive breastfeeding during the neonatal period is associated with exclusive breastfeeding until 3 months.

In 2009, the Centers for Disease Control and Prevention implemented the Maternity Practices in Infant Nutrition and Care (mPINC) survey in all US birth facilities to assess breastfeeding-related maternity practices. Maternity practices and hospital policies are known to influence breastfeeding, and Alabama breastfeeding rates are very low.

Our objective was to assess whether staff training and structural-organizational aspects of care, such as policies, were associated with infants’ breastfeeding behaviors 24 to 48 hours postpartum.

We linked 2009 mPINC data from 48 Alabama hospitals with birth certificate and newborn screening databases. We used data collected 24 to 48 hours postpartum to classify 41 536 healthy, term, singleton infants as breastfed (any breast milk) or completely formula fed and examined associations with hospitals’ mPINC scores in comparison with the state mean. We conducted multilevel analyses to assess infants’ likelihood of being breastfed if their birth hospital scores were lower versus at least equal to the Alabama mean, accounting for hospital clustering, demographics, payment method, and prenatal care.

The odds of breastfeeding were greater in hospitals with a higher-than-state-mean score on the following: new employees’ breastfeeding education, nurses’ receipt of breastfeeding education in the past year, prenatal breastfeeding classes offered, having a lactation coordinator, and having a written breastfeeding policy. The number of recommended elements included in hospitals’ written breastfeeding policies was positively associated with newborn breastfeeding rates.

Educating hospital staff to improve breastfeeding-related knowledge, attitudes, and skills; implementing a written hospital breastfeeding policy; and ensuring continuity of prenatal and postnatal breastfeeding education and support may improve newborn breastfeeding rates.

Employer support is important for mothers, as returning to work is a common reason for discontinuing breastfeeding. This article explores support available to breastfeeding employees of hospitals that provide maternity care.

This study aimed to describe the prevalence of 7 different types of worksite support and changes in these supports available to breastfeeding employees at hospitals that provide maternity care from 2007 to 2011.

Hospital data from the 2007, 2009, and 2011 Centers for Disease Control and Prevention Survey on Maternity Practices in Infant Nutrition and Care (mPINC) were analyzed. Survey respondents were asked if the hospital provides any of the following supports to hospital staff: (1) a designated room to express milk, (2) on-site child care, (3) an electric breast pump, (4) permission to use existing work breaks to express milk, (5) a breastfeeding support group, (6) lactation consultant/specialist available for consult, and (7) paid maternity leave other than accrued vacation or sick leave. This study was exempt from ethical approval because it was a secondary analysis of a publicly available dataset.

Of the 7 worksite supports in hospitals measured, 6 increased and 1 decreased from 2007 to 2011. Across all survey years, more than 70% of hospitals provided supports for expressing breast milk, whereas less than 15% provided direct access to the breastfeeding child through on-site child care, and less than 35% offered paid maternity leave. Results differed by region and hospital size and type. In 2011, only 2% of maternity hospitals provided all 7 worksite supports; 40% provided 5 or more.

The majority of maternity care hospitals (> 70%) offer breastfeeding supports that allow employees to express breast milk. Supports that provide direct access to the breastfeeding child, which would allow employees to breastfeed at the breast, and access to breastfeeding support groups are much less frequent than other supports, suggesting opportunities for improvement.

Maternal anxiety and depression may impair maternal intention, motivation, and self-efficacy in multiple domains associated with child health including breastfeeding.

We tested the hypothesis that mothers who experience substantial anxiety during pregnancy or the postpartum period are at increased risk for reduced initiation, exclusivity, and continuation of breastfeeding.

We obtained data on 255 Canadian pregnant women from the Maternal Adversity, Vulnerability and Neurodevelopment (MAVAN) study recruited between June 2004 and February 2009. We utilized data collected from 18 to 23 weeks gestation through 12 months postpartum. Multivariate logistic regression was used to assess whether scores on the Hamilton Anxiety Scale (HAM-A) and State-Trait Anxiety Inventory (STAI) were associated with initiation, exclusivity, and continuation of breastfeeding.

Prenatal anxiety was not associated with breastfeeding outcomes. In adjusted models, a single point increase in HAM-A scores at 3 months postpartum was associated with an 11% reduction in the odds of exclusive breastfeeding at 6 months (adjusted odds ratio [aOR] = 0.89; 95% CI, 0.80-0.99). A single point increase in STAI State and STAI Trait scores at 3 months postpartum was associated with a 4% (aOR = 0.96; 95% CI, 0.92-0.99) and 7% (aOR = 0.93; 95% CI, 0.86-1.00) reduction, respectively, in the odds of any breastfeeding at 12 months.

Our findings suggest a relationship between maternal anxiety and reduced exclusivity and continuation of breastfeeding. Maternal anxiety should be actively monitored and managed appropriately in the postpartum period to support optimal breastfeeding practices.
