Outcome Evaluation of the You Can Do It Initiative to Promote Exclusive Breastfeeding Among Women Enrolled in the New York State WIC Program by Race/Ethnicity

Unpacking Breastfeeding Disparities: Baby-Friendly Hospital Designation Associated with Reduced In-Hospital Exclusive Breastfeeding Disparity Attributed to Neighborhood Poverty

OBJECTIVES

To examine US in-hospital exclusive breastfeeding (EBF) and the associations with Baby-Friendly designation and neighborhood sociodemographic factors.

METHODS

Hospital data from the 2018 Maternity Practices in Infant Nutrition and Care survey were linked to hospital zip code tabulation area (ZCTA) sociodemographic data from the 2014-2018 American Community Survey (n = 2,024). The percentages of residents in the hospital ZCTA were dichotomized based on the relative mean percentage of the hospital's metropolitan area, which were exposure variables (high/low Black hospitals, high/low poverty hospitals, high/low educational attainment hospitals) along with Baby-Friendly designation. Using linear regression, we examined the associations and effect measure modification between Baby-Friendly designation and hospital sociodemographic factors with in-hospital EBF prevalence.

RESULTS

US mean in-hospital EBF prevalence was 55.1%. Baby-Friendly designation was associated with 9.1% points higher in-hospital EBF prevalence compared to non-designated hospitals [95% confidence interval (CI): 7.0, 11.2]. High Black hospitals and high poverty hospitals were associated with lower EBF prevalence (difference= -3.3; 95% CI: -5.1, -1.4 and - 3.8; 95% CI: -5.7, -1.8). High educational attainment hospitals were associated with higher EBF prevalence (difference = 6.7; 95% CI: 4.1, 9.4). Baby-Friendly designation was associated with significant effect measure modification of the in-hospital EBF disparity attributed to neighborhood level poverty (4.0% points higher in high poverty/Baby-Friendly designated hospitals than high poverty/non-Baby-Friendly designated hospitals).

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

BACKGROUND

Pregnant participants who perceived that the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) recommends breastfeeding only were more likely to have better early breastfeeding outcomes.

OBJECTIVES

Our objective was to examine the association between prenatal perception of WIC's breastfeeding recommendations and breastfeeding duration through the first year of infant life.

METHODS

This observational study used a national longitudinal sample of 1594 pregnant participants in the WIC Infant and Toddler Feeding Practices Study-2 in 2013. Four measures of breastfeeding duration were used: 1) a discrete measure of exclusive breastfeeding through 5 mo; 2) a continuous measure of exclusive breastfeeding (in days up to 7 mo); 3) a discrete measure of any breastfeeding through 11 mo; and 4) a continuous measure of any breastfeeding (in days up to 13 mo). The primary explanatory variable was the participant's prenatal perception of whether WIC recommended breastfeeding only. The univariate analyses of time to breastfeeding cessation were performed using Kaplan-Meier curves. The Cox regression model was adopted to estimate the likelihood of breastfeeding outcomes over time. All analyses accounted for complex survey design effects.

RESULTS

Compared with their peers who perceived WIC to recommend formula only or both breastfeeding and formula equally, participants who perceived WIC as recommending breastfeeding only were less likely to stop exclusive breastfeeding through 5 mo (HR = 0.83; 95% CI: 0.69, 0.99) or to stop any breastfeeding through 11 mo (HR = 0.80; 95% CI: 0.69, 0.92), without controlling for prenatal infant feeding intentions. Similar patterns were observed in the 2 continuous measures, as they were also less likely to stop exclusive breastfeeding by 7 mo (HR = 0.78; 95% CI: 0.69, 0.90) or to stop any breastfeeding by 13 mo (HR = 0.82; 95% CI: 0.71, 0.95).

CONCLUSIONS

Prenatal perception of WIC's breastfeeding recommendation can be a useful predictor of breastfeeding duration in WIC participants.

Exclusive breastfeeding in African American women: A concept analysis

AIM

To report an analysis of the concept of exclusive breastfeeding (EBF) in African American women.

BACKGROUND

EBF is the gold standard for infant nutrition from birth until 6 months. The rate of EBF in United States is low-26%, with African American women having the lowest rates. The low rates of EBF in this population are strongly attributed to bias, racism and generational trauma. Therefore, clarifying the concept of EBF with respect to these factors is important for promoting EBF rates of this population.

DESIGN

Concept analysis.

DATA SOURCES

Search was conducted in four databases (CINAHL, PubMed, PsycINFO and Scopus) for articles published between 2001 and 2021. A total of 30 articles (20 quantitative, seven qualitative and three mixed methods) clarified the concept. Relevant literature emanated from diverse disciplines examining historical and present maternal and infant health.

METHODS

Concept analysis using Rodger's evolutionary method.

RESULTS

An operational definition of the concept of EBF in African American women was developed from the identified antecedents (modifiable and non-modifiable), defining attributes and consequences of the concept. Access to breastfeeding resources, maternal (prenatal intention to breastfeed, smoking status, attitude towards breastfeeding), infant (skin-to-skin care, successful latching and weight) and contextual factors (socioeconomic, occupational and cultural) predict EBF. The primary attributes of EBF were physiological, physical, psychological and relational. Consequences of EBF were positive health outcomes for, and increased bonding between, mother and infant.

CONCLUSION

This concept analysis is the first identifying modifiable and non-modifiable antecedents of EBF. The analysis provides an operational definition for EBF in African American women which is useful to promote understanding of breastfeeding. This new concept examines the historic societal trauma associated with wet nursing and reframes breastfeeding as a positive maternal and infant health behaviour.

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

BACKGROUND

Prenatal psychosocial factors predict breastfeeding practices but are not assessed in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

OBJECTIVES

This study examined how prenatal perceptions of WIC's breastfeeding recommendations were associated with early breastfeeding outcomes.

METHODS

This study used longitudinal data from a national sample of 2053 pregnant participants in the WIC Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2) in 2013, the only national data assessing prenatal perceptions of WIC's breastfeeding recommendations. Early breastfeeding outcomes included breastfeeding initiation, breast milk first fed after birth, breastfeeding in the first hour, breast milk first fed after leaving the hospital, and breastfeeding status at the first and third months. The primary predictor was the participant's prenatal perception of whether WIC recommended breastfeeding only or not. Log-binomial regression was used with adjustment for socio-demographics, previous breastfeeding, WIC participation, breastfeeding support, and infant feeding intentions (IFI).

RESULTS

Without controlling for IFI, the perception of WIC recommending breastfeeding only predicted breastfeeding outcomes positively. The risk ratio (RR) associated with prenatal perceptions varied from 1.14 (95% CI: 1.03, 1.25; P = 0.008) for breastfeeding in the first hour, to 1.27 (95% CI: 1.12, 1.43; P < 0.001) for breast milk first fed after leaving hospital, to 1.66 (95% CI: 1.35, 2.04; P < 0.001) for 3-mo breastfeeding only. After controlling for IFI, the RRs were 1.13 (95% CI: 1.02, 1.24; P = 0.017) for breastfeeding in the first hour, 1.20 (95% CI: 1.06, 1.35; P = 0.004) for breast milk first fed after leaving hospital, and 1.49 (95% CI: 1.21, 1.84; P < 0.001) for 3-mo breastfeeding only, suggesting that prenatal perception was independently associated with breastfeeding outcomes.

CONCLUSIONS

Prenatal perception of WIC's breastfeeding recommendations can be regarded as a new psychosocial predictor of breastfeeding and a possible target for future intervention.

Breastfeeding counseling based on formative research at primary healthcare Services in Mexico

BACKGROUND

Breastfeeding rates in Mexico are far from World Health Organization (WHO) recommendations with 28.8% of Exclusive Breastfeeding (EBF) under 6 months of age, according to the 2018 National Health and Nutrition Survey. Formative research has shown that culturally appropriate counseling is an effective breastfeeding intervention. The objective of the current study was to evaluate the effect of interpersonal counseling on EBF in a primary healthcare center in Tijuana, México.

METHODS

This was a randomized controlled trial pilot with a sample of mothers with infants under 4 months of age from a primary care center. Participants were randomized into two groups: 1) Control group, received counseling on immunizations and standard infant feeding information, and 2) Intervention group, receiving breastfeeding counseling using a socio-ecological framework. Changes in breastfeeding attitudes, self-efficacy and EBF were evaluated at 2 months post-intervention.

RESULTS

A total of 80 mothers completed the 2 month follow up assessment (40 in each group). The mean age at baseline was 26.4 years for mothers and 1.4 months for infants. There was a 30% increase in EBF at 2 months follow up in the intervention group and 15% decrease in the control group post-intervention. We observed a significant improvement in breastfeeding attitudes (P = 0.0001), self-efficacy (P = 0.046) and EBF (P = 0.0001) in the intervention group. Reported obstacles were discomfort of breastfeeding in public (23%), infant dissatisfaction (23%), pain (19%), insufficient milk supply (15%) and returning to work (8%).

CONCLUSIONS

Breastfeeding counseling based on previous formative research improved breastfeeding attitudes, self-efficacy and practices in this population. These findings suggest that the promotion of breastfeeding utilizing a socio-ecological framework may improve breastfeeding rates by addressing the needs of women within their varying sociocultural contexts.

Impact of breastfeeding interventions among United States minority women on breastfeeding outcomes: a systematic review

BACKGROUND

In the U.S., strong ethnic/racial, socioeconomic, demographic, and geographic breastfeeding (BF) inequities persist, and African American and Hispanic women are less likely to meet their breastfeeding goals compared to White women. This systematic review (SR) was designed to answer the question: What is the impact of breastfeeding interventions targeting ethnic/racial minority women in the U.S. on improving BF initiation, duration and exclusivity rates?

METHODS

The SR was conducted following the Institute of Medicine Guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. The study protocol was developed and registered a priori in PROSPERO (ID#CRD42020177764). The electronical databases searched was MEDLINE All (Ovid). Search strategies were led by the team's expert public health librarian using both controlled vocabulary and free text queries and were tested against a validated set of relevant papers included in existing reviews. The GRADE methodology was used to assess the quality of the studies.

RESULTS

We included 60 studies that had randomized (n = 25), observational (n = 24), quasi-experimental (n = 9), or cross-sectional (n = 2) designs. The studies focused on populations that were multi-ethnic/racial (n = 22), only Hispanic (n = 24), only Black (n = 13), and only American Indian (n = 1). The study interventions were classified following the socioecological model: macrosystem/policy level (n = 6); community level (n=51), which included healthcare organizations (n = 34), The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) (n = 9), and community organizations/public health institutions (n = 8); and  interpersonal level (n = 3).

CONCLUSIONS

Policy and community level interventions delivered through WIC, healthcare facilities, and community agencies) are likely to improve BF outcomes among women of color. The combination of interventions at different levels of the socioecological model has not been studied among minority women in the U.S. Implementation science research is needed to learn how best to scale up and sustain effective BF interventions, taking into account the needs and wants of minority women. Thus, it is strongly recommended  to conduct large scale implementation research studies addressesing how to strengthen the different health and social environments surrounding women of color in the U.S. to improving their BF outcomes.

Breastfeeding Duration Is Associated With WIC Site-Level Breastfeeding Support Practices

OBJECTIVE

To describe Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) site-level breastfeeding support practices and associations with breastfeeding outcomes.

DESIGN

Secondary analysis of WIC Infant and Toddler Feeding Practices Study-2, including data from interviews with caregivers of infants and interviews and surveys with staff from 27 WIC state agencies and 80 study sites.

PARTICIPANTS

A total of 1,235 mothers of breastfed infants participating in the WIC Infant and Toddler Feeding Practices Study-2.

MAIN OUTCOME MEASURE

Any and fully breastfeeding 2, 6, and 12 months postpartum.

ANALYSIS

Descriptive statistics described WIC site-level breastfeeding supports. Multilevel mixed modeling of breastfeeding at 2, 6, and 12 months, controlling for site- and participant-level characteristics.

RESULTS

Five WIC site-level supports were significantly and independently associated with any and fully breastfeeding: access to breastfeeding peer counselors, access to International Board Certified Lactation Consultants, postnatal home visits, allowing any WIC staff member to provide breast pump education, and having a policy not to provide formula during the first 30 days postpartum. Likelihood of any and fully breastfeeding increased with each additional site-level support present (odds ratio = 1.09, 95% confidence interval, 1.06-1.12; and odds ratio = 1.26, 95% confidence interval, 1.21-1.31, respectively).

CONCLUSIONS AND IMPLICATIONS

Positive associations between site-level supports and breastfeeding at 2, 6, and 12 months were observed. Additional research is needed to understand how site-level supports interrelate and whether specific combinations are more effective, and to identify variations in implementation of breastfeeding supports.

Combined pro-breastfeeding practices are advantageous in facilities providing maternity and newborn services

This study aimed to evaluate the association between a set of pro-breastfeeding practices in facilities providing maternity and newborn services and the prevalence of exclusive breastfeeding at 30 days postpartum, considering the contribution of each practice. A cross-sectional study nested within a cohort study was conducted with 287 women who delivered healthy term infants in two hospitals in southern Brazil. They were interviewed at home at 30 days postpartum. The following practices were evaluated: skin-to-skin contact soon after birth, breastfeeding in the first hour, uninterrupted rooming-in, professional support with breastfeeding, breastfeeding guidance, encouragement to breastfeed on demand, no supplementation with infant formula, and no pacifier use. A score of pro-breastfeeding practices was calculated using a logistic model, which allowed each practice to have its discriminatory capacity and difficulty estimated individually. Poisson regression was used to estimate the association between exclusive breastfeeding at 30 days and the pro-breastfeeding practice score. The prevalence of exclusive breastfeeding at 30 days was 61.7%. The practices with greatest discriminatory capacity, that is, those that contributed most to the score estimates, were professional support with breastfeeding, breastfeeding guidance, and encouragement to breastfeed on demand. The most difficult ones were breastfeeding in the first hour, encouragement to breastfeed on demand, and non-utilization of infant formula. For each unit (standard deviation) of increase in the score, there was an increase of 20% in the prevalence of exclusive breastfeeding at 30 days. We conclude that the set of pro-breastfeeding practices assessed here increased the effect of these practices on exclusive breastfeeding rates at 30 days.

Implementing a WIC-Based Intervention to Promote Exclusive Breastfeeding: Challenges, Facilitators, and Adaptive Strategies

OBJECTIVE

Understand factors that contributed to the implementation of a successful multicomponent intervention to promote exclusive breastfeeding (EBF) within Special Supplemental Nutrition Program for Woman, Infants, and Children (WIC) clinics.

DESIGN

Qualitative study of staff implementers' experiences using implementation status reports, facilitated group discussion immediately after implementation, and WIC administrative data.

SETTING

WIC staff from 12 clinics participated in an EBF Learning Community composed of 8 intervention trainings and ongoing support from trainers and peers.

PARTICIPANTS

A total of 47 WIC staff including 11 directors, 20 other administrators, 8 nutritionists, and 6 peer counselors.

INTERVENTION

A WIC-integrated EBF promotion initiative, supported through a Learning Community, composed of prenatal screening, tailored trimester-specific counseling, and timely postpartum follow-up.

PHENOMENON OF INTEREST

Challenges and facilitators to implementation within clinics.

ANALYSIS

Iterative qualitative analysis using directed, emergent, and thematic coding.

RESULTS

Implementation experiences were characterized by (1) perceived benefits of implementation, including improved EBF knowledge and counseling confidence among staff; and (2) managing implementation, including responding to challenges posed by clinic settings (resources, routine practices, values, and perceptions of mothers) through strategies such as adapting clinic practices and intervention components.

CONCLUSIONS AND IMPLICATIONS

Implementation was shaped by clinic setting and adaptive strategies. Future WIC interventions may benefit from formal consideration of intervention fit with local clinic setting and allowable adaptations.
