RESUMO
BACKGROUND: The critical time to continue or stop breastfeeding is during the first month after hospital discharge. Mothers receive lactation and physical support by fathers and others bottle-feeding human or formula milk to their infants. PURPOSE: To describe the effect of feeders (mothers, fathers, and others) and different milk feeding on infants' weekly exclusive breastfeeding rates, from birth to 1 month after discharge. METHODS: This study was a secondary analysis of a descriptive longitudinal study of mothers' (full-term: n = 77; late preterm: n = 39) breastfeeding experience, frequency of feeding, and infant feeding behaviors. Mothers completed a weekly questionnaire of who (mothers, fathers, and others) fed their infants human or formula milk by direct breastfeeding or bottle-feeding. RESULTS: More than 60% of mothers reported fathers and others bottle-fed their infants. Exclusive breastfeeding rates were significantly higher when only mothers fed their infants at week 1 ( P < .001), week 3 ( P < .05), and week 4 ( P < .05). Exclusive breastfeeding rates were negatively affected across time by bottle-feeding any human or formula milk for all feeders. When fathers bottle-fed their infants at week 1, the relative rates of exclusive breastfeeding at week 4 decreased to 52% (OR = 0.103; 95% CI, 0.26-0.404; P < .0001). IMPLICATION FOR PRACTICE: Individuals providing early bottle-feeding adversely affect breastfeeding outcomes. Providers need to address maternal and paternal knowledge gaps about early breastfeeding practice. IMPLICATIONS FOR RESEARCH: Further research is needed to explore clinical standard of care for management of infant weight loss, early supplementation, and support of exclusive breastfeeding outcomes.

BACKGROUND: In the United States, there are racial disparities in 6 months of exclusive breastfeeding. Only, 25.8% of American infants were breastfed for the first 180 days of life, with African American infants least (19.8%) exclusively breastfed in 2018. PURPOSE: The meta-ethnography explored the breastfeeding support for African American women in the United States. DATA SOURCES: The online databases of American Psychological Association, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, PubMed, and Scopus were searched with key words, and the search was not limited by the year of publication. STUDY SELECTION: The inclusion criteria for the study selection entailed all qualitative studies conducted on breastfeeding support among self-identified African American women in the United States, written in English language, peer reviewed, or dissertation. The initial search produced 905 articles of which 8 met the eligibility criteria. DATA EXTRACTION: Data extraction and analysis were guided by Noblit and Hare's (1988) meta-ethnography approach. The analysis process was completed by a team of researchers, inclusive of breastfeeding experts. RESULTS: Five overarching themes emerged including trustworthy information; early postpartum support by key influencers; maternal culture; tangible resources, and Black mothers' empowerment. IMPLICATIONS FOR PRACTICE AND RESEARCH: Social support is a major determinant for the initiation and continuation of breastfeeding among African American women in the United States. Future longitudinal studies are warranted to explore the social support of breastfeeding among African American women in the United States.

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.

BACKGROUND: The World Health Organization recommends exclusive breastfeeding for the first 6 months of an infant's life and continued breastfeeding for 2 years. The global rate of exclusive breastfeeding is low at 33%. Thus, it is important to identify philosophical and theory-based strategies that can promote exclusive breastfeeding. The aim of the study was to identify philosophical schools of thought and theories used in research on promoting the practice of exclusive breastfeeding. METHODS: A scoping review using Arksey and O'Malley's framework explored the phenomenon of exclusive breastfeeding practice promotion. Searches were conducted using CINAHL Plus full-text, PubMed, APA PsycInfo, and Academic Search Premier. Search terms included theory, philosophy, framework, model, exclusive breastfeeding, promotion, support, English, and publication between 2001-2022. RESULTS: The online search yielded 1,682 articles, however, only 44 met the inclusion criteria for the scoping review. The articles promoting exclusive breastfeeding used pragmatism (n = 1) or phenomenology (n = 2) philosophies and theories of self-efficacy (n = 10), theory of planned behaviour (n = 13), social cognitive theories (n = 18) and represented 16 countries. Theories of self-efficacy and planned behaviour were the most used theories. CONCLUSIONS: This review suggests that theories and models are increasingly being used to promote exclusive breastfeeding. Orienting exclusive breastfeeding programmes within theoretical frameworks is a step in the right direction because theories can sensitize researchers and practitioners to contextually relevant factors and processes appropriate for effective exclusive breastfeeding strategies. Future research should examine the efficacy and effectiveness of theory-informed exclusive breastfeeding programmes over time. Such information is important for designing cost-effective EBF programmes.

BACKGROUND: Emotion regulation is a regulatory process to modify emotional activation in a wide range of situations and shows potential effects to reduce pain and emotional distress. The purpose of this review was to enhance an understanding of the role of emotion regulation strategies and their outcomes in reducing women's pain from labor to 3 months postpartum. DESIGN: Integrative review. METHODS: The literature was reviewed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The search was conducted using electronic databases CINAHL, PsycINFO, PubMed, Scopus, and ProQuest dissertation from 1990-2019. RESULTS: Nine publications were included. Two emotion regulation strategies, mindfulness and distraction, were used. The findings revealed that prolonged training in mindfulness-based interventions produced significant improvements in decreasing pain intensity during labor and increasing maternal comfort 2 hours postpartum. The distraction strategy showed a significant decrease in pain intensity during labor for women who were trained and self-practiced during the prenatal period. CONCLUSIONS: Both mindfulness and distraction would be offered to pregnant women as part of alternative self-pain management strategies to prepare them for dealing with pain and other discomforts. Future research needs to test the effects of the intervention beyond childbirth.

BACKGROUND: Thirty percent of women who seek professional breastfeeding support require assistance with ongoing breast and nipple pain and < 50% of women report resolution of their pain. It is unknown if there is a molecular risk for ongoing breast and nipple pain during breastfeeding. Aim -To evaluate associations among breast and nipple pain sensitivity and candidate pain sensitivity single-nucleotide polymorphisms [SNPs], (COMT rs6269, rs4633, rs4818, rs4680 and OXTR rs2254298, rs53576) in breastfeeding women. Design - A secondary analysis of a pilot randomized controlled trial of a pain self-management intervention conducted over 6 weeks postpartum. Setting and Participants - Sixty women were recruited from two hospital settings after birth. Methods - All participants underwent standardized mechanical somatosensory testing for an assessment of pain sensitivity and provided baseline buccal swabs for genetic analysis. At 1, 2, and 6 weeks postpartum, women self-reported breast and nipple pain severity using a visual analogue scale. Results - Women with the minor allele OXTR rs53576 reported 8.18-fold higher breast and nipple pain severity over time. For every 1-unit increase in Mechanical detection threshold and windup ratio, women reported 16.51-fold and 4.82-fold higher breast and nipple pain severity respectively. Six women with the OXTR rs2254298 minor allele reported allodynia. Conclusion - The presence of OXTR alleles in women with enhanced pain sensitivity suggests a phenotype of genetic risk for ongoing breast and nipple with potential for pain-associated breastfeeding cessation. Somatosensory testing identified women who reported higher breast and nipple pain during the first weeks of breastfeeding.

PROBLEM IDENTIFICATION: To date, there is limited study of the end of treatment (EOT) transition experiences and needs of children/adolescents with cancer and their parents. LITERATURE SEARCH: A systematic search identified primary research focusing on EOT, describing child, adolescent, and parental perceptions, experiences, and needs during this transition period. Of 170 articles identified, 22 met inclusion criteria. DATA EVALUATION/SYNTHESIS: Studies were appraised for level and quality of evidence. Narrative synthesis was performed to extract themes and integrate the literature. Family members' perceived needs, factors influencing the EOT experience, and consequences of this transition emerged as themes. CONCLUSIONS: Uncertainty and heightened anxiety at EOT highlight the need for increased education and support for family members. Family functioning and distress influence the EOT experience, with variable effects on each family member. There is a call for individualized interventions to promote coping and positive outcomes.

OBJECTIVES: To evaluate the effect of early breastfeeding cessation on incidence of diarrhea in a cohort of U.S. infants. DESIGN, SAMPLE, AND MEASUREMENTS: A secondary data analysis was conducted using data from 2,340 mother-infant dyads participating in the Infant Feeding Practices Study II. We examined associations between duration of feeding type (e.g., exclusive breastfeeding [EBF], any breastfeeding [BF], formula feeding) and incidence of diarrhea before one year. RESULTS: The sample included mother-infant dyads that were 86.2% White, 3% Black, and 5% Hispanic. Interruption of EBF before 3 months was significantly associated with higher odds of having diarrhea at 6 months (OR = 1.80, p value ≤ 0.01) and between 6 and 12 months (OR = 1.45, p ≤ .01). Breastfeeding interruption before 6 months was associated with higher odds of having diarrhea at 6 months (OR = 3.19, p ≤ .01). Formula feeding for ≥3 months was associated with higher odds of diarrhea between 6 and 12 months. CONCLUSIONS: Exclusive breastfeeding for 3 months accompanied by any breastfeeding for 6 months provided the most protective effect against diarrhea. Public health interventions should address disparities in breastfeeding practices and provide support across clinical, workplace and community settings. Research should include more diverse population groups.

BACKGROUND: Over 90% of women experience pain during breastfeeding initiation and lack strategies to self-manage breast and nipple pain. Guided by the Individual and Family Self-Management Theory, a breastfeeding self-management (BSM) intervention targeted women's knowledge, beliefs, and social facilitation to manage their breast and nipple pain and achieve their breastfeeding goals. OBJECTIVES: The purpose of this longitudinal pilot randomized control trial (RCT) was to test the preliminary efficacy of the BSM intervention on general and specific pain related to breastfeeding. METHODS: Sixty women intending to breastfeed were approached within 48 hours of delivery to participate in this pilot RCT (30 randomized to the BSM intervention and 30 randomized to the control group). All participants provided baseline data before discharge and pain and breastfeeding measures at 1, 2, and 6 weeks. Participants in the BSM intervention group received educational modules addressing breast and nipple pain and biweekly, text-based nurse coaching and completed a daily breastfeeding journal. RESULTS: Women in the BSM intervention group reported significantly less breast and nipple pain at 1 and 2 weeks using a visual analog scale (p < .014 and p < .006) and at 2 weeks using the Brief Pain Inventory intensity scale (p < .029), but no difference in breastfeeding duration. DISCUSSION: The BSM intervention pilot demonstrates a positive effect on breastfeeding specific and overall generalized pain. Future investigation is needed to identify at-risk women of ongoing breastfeeding pain and develop precision interventions to sustain this beneficial health behavior for mothers and infants.

OBJECTIVE: Pain disability is a complex and challenging problem that impacts the daily lives of individuals living with persistent pain. Although this concept is measured throughout pain populations, conceptual clarity is needed to identify the defining characteristics and further understand what comprises this experience for clinical translation. DESIGN: We completed a concept analysis to identify major attributes and provide a broad framework of pain disability for improved recognition throughout the discipline of nursing. DATA SOURCES: Literature searches in PubMed, CINAHL, PsychINFO, and Scopus identified 39 relevant cross-disciplinary articles published between January 1990 and November 2017. REVIEW/ANALYSIS METHODS: We implemented Avant and Walker's method of concept analysis to establish the attributes, antecedents, and consequences of pain disability. RESULTS: Two major attributes of pain disability are discussed, including (1) physical and/or psychological responses leading to a functional loss; and (2) the degree of ability to fulfill role expectations. The antecedent to the development of pain disability is a painful trigger. Three leading consequences are identified as suffering, pain reactivity, and secondary loss. CONCLUSIONS: Pain disability is a fluid concept that is characterized by the subjective experiences of the individual. A new conceptualization of pain disability is offered as the inability to maintain role expectations due to the result of a painful trigger and subsequent physical and/or psychosocial dysfunction.

The majority of women experience pain during breastfeeding initiation with few strategies to manage breast and nipple pain. In fact, women cite breast and nipple pain as among the most common reasons for breastfeeding cessation. To address this important issue, we developed a breastfeeding self-management (BSM) intervention, based on the Individual and Family Self-Management Theory Framework. In this framework, self-management is conceptualized as a process in which women use knowledge, beliefs, and social facilitation to achieve breastfeeding goals. The purpose of this longitudinal pilot randomized controlled trial was to test the feasibility, acceptability, and preliminary efficacy of the BSM intervention with women initiating breastfeeding. Recruitment of 60 women intending to breastfeed occurred within 48 hr of delivery and women were randomized to either the intervention or usual care group. The BSM intervention group received BSM education modules that included information of how to manage breast and nipple pain and self-management support through biweekly texting from the study nurse, and were asked to complete a daily breastfeeding journal. Primary outcomes measured at baseline, 1, 2, and 6 weeks will be used to (a) evaluate feasibility, acceptability, and preliminary efficacy of the BSM intervention, and (b) assess the influence of protective and risk factors of breastfeeding pain (including individual genetic polymorphisms related to pain sensitivity) on process variables for self-management of breastfeeding and breastfeeding pain, and on proximal (breastfeeding pain severity and interference, breastfeeding frequency) and distal outcomes (breastfeeding exclusivity and duration and general well-being).

PURPOSE: In 2014, the Youth Acute Pain Functional Ability Questionnaire (YAPFAQ) was developed to investigate patient's self-rated functional ability during times of acute pain in the inpatient clinical setting. Although it has great potential, the application of this tool has not been made a standard of care. The purpose of this multiple methods study was to determine if, through an educational intervention, hospital staff could consistently document the YAPFAQ in children with sickle cell disease (SCD) during a vaso-occlusive episode. DESIGN AND METHODS: Twenty-two staff members participated in an educational intervention and semi-structured group discussions. Pre/post surveys measured knowledge of the YAPFAQ before and after the intervention. Group discussions were recorded, transcribed verbatim, and analyzed for thematic clusters. Retrospective chart reviews of children with SCD were reviewed for YAPFAQ documentation frequency before and after the intervention. RESULTS: Staff knowledge of who completes the YAPFAQ increased after the intervention, (p<.001). YAPFAQ documentation decreased after the intervention, (p<.001). Qualitative analysis identified personal, physical, and patient barriers to completing the YAPFAQ and multiple recommendations to change the method of documentation in the electronic health records (EHR). CONCLUSIONS: Although the staff expressed high interest in utilizing the YAPFAQ, application was inhibited by delayed translation to the EHR. The YAPFAQ continues to hold high potential for directing nursing care, but requires staff investment for clinical practice change. PRACTICAL APPLICATIONS: A seamless integration between nursing education and translation through EHR is recommended as technology continues to integrate into nursing practice.
RESUMO
BACKGROUND: Breast milk is the gold standard of nutrition for preterm infants. Yet, initiation of direct breastfeeding before 32 weeks' postconceptional age (PCA) is not common practice in many neonatal intensive care units (NICUs). Our clinical question was, "In preterm infants, when is it safe to initiate breastfeeding in infants <32 weeks PCA receiving enteral feedings?" SEARCH STRATEGY: A review of the literature was compiled between February 2013 and January 2015 by using the following databases: CINAHL, Cochrane Systematic Review, Scopus, and PubMed. Articles found were written in English and published after 1985. Key words were utilized during searches and references were hand checked. RESULTS: Our review revealed that stable preterm infants maintain their physiological status during exposure to the breast as early as 27 to 28 weeks' PCA. Several studies demonstrated infants during breastfeeding compared with bottle-feeding experienced minimal variation in oxygen saturation and heart rate during feeding. Some infants exposed to the breast before 30 weeks' PCA were exclusively breastfeeding (direct breastfeeding and breast milk) at 32.8 weeks' PCA. Skin-to-skin mother-infant contact is crucial to the successful transition to direct breastfeeding. IMPLICATIONS FOR PRACTICE AND RESEARCH: The transition from enteral feedings to direct, exclusive breastfeeding should involve frequent mother-infant skin-to-skin contact requiring support and guidance from the NICU staff. Future research should involve creating standard protocols within NICUs to facilitate breastfeeding transition and exploring barriers that may prevent the preterm infant from achieving direct, exclusive breastfeeding.

The purpose of this integrative review was to uncover information regarding emotional and other types of support required by mothers providing breast milk for infants in the neonatal intensive care unit (NICU). These high-risk infants are often unable to directly breastfeed and, thus, mothers need to pump their breast milk for weeks to months, which can be both a pleasing experience that increases satisfaction and infant involvement, while at the same time being an uncomfortable and tiring endeavor. Understanding this notion is important because pumping at least 8 times each day is central to increasing or maintaining breast milk production. Articles were gathered using PubMed and CINAHL databases. Forty-four sources were chosen for inclusion in this review. Search terms included "breastfeeding," "pumping," "neonatal intensive care unit," "emotional support," and "breast milk." We identified that the emotional and practical support for NICU mothers is different from those of other breastfeeding mothers, especially around the development of early bonding behaviors. These mothers require significant ongoing emotional support from healthcare professionals and their partners and peers. Healthcare providers need to monitor breast milk production and provide educated encouragement that anticipates breastfeeding challenges, especially when the mother is pumping for an extended period of time while their infant is maturing in the NICU. Effective providers' support may be best provided by selectively bundling interventions to support pumping initiation and transition to direct breastfeeding.

OBJECTIVE: To synthesize evidence from qualitative studies on the experiences of women from around the world who exclusively breastfed their full-term infants. DATA SOURCES: CINAHL Plus, PubMed, APA PsycInfo, Scopus, and ProQuest Dissertation & Theses Global. STUDY SELECTION: We selected reports of qualitative studies that were conducted in high-, middle-, and low-income countries; published between January 2001 and February 2022 in English; and focused on the experiences of women who exclusively breastfed their full-term infants. DATA EXTRACTION: We extracted the following data from included studies: methodological characteristics (i.e., country of origin, authors' disciplines, research design, sample size, sampling, data collection, and data analysis method), participants' demographics (i.e., age, parity, marital status, education, and exclusive breastfeeding duration) and direct participant quotes, and key concepts and themes about women's experiences of exclusive breastfeeding. We managed and stored extracted data using a Microsoft Excel spreadsheet. DATA SYNTHESIS: We synthesized reciprocal translations using Noblit and Hare's approach to meta-ethnography. Five overarching themes emerged from the meta-synthesis: Favorable Conditions, Not a Smooth Journey,Support, Determination and Perseverance, and Reflections on Benefits. CONCLUSION: In the included studies, participants experienced challenges with exclusive breastfeeding; however, they also recounted benefits. We recommend 6-month maternity leave and support from family and health care professionals to improve rates of exclusive breastfeeding.

BACKGROUND: Aging leads to a decline in muscle mass and strength, contributing to frailty and decreased quality of life. Sirolimus (rapamycin) , an mTOR inhibitor, has shown potential in preclinical studies to extend lifespan and improve health span. This study evaluates the safety and efficacy of once-weekly sirolimus (rapamycin) administration on muscle strength and endurance in older adults engaged in a 13-week exercise program. METHODS: This randomized, double-blind, placebo-controlled trial will enroll 40 participants aged 65-85. Participants will be randomly assigned to receive either sirolimus (rapamycin) 6 mg/week or placebo for 13 weeks, in conjunction with an at-home exercise program. The primary outcome measure is the change in muscle strength and endurance, assessed by the 30-Second Chair-Stand Test. Secondary outcome measures include adverse events, changes in muscle strength and endurance as measured by the 6-min walk test, handgrip strength, and participant-reported outcomes using the SF-36 survey. Assessments will be conducted at baseline, mid-intervention (week 6), and post-intervention (week 13). Blood samples will be collected for hematology and biochemistry analyses, including full blood count, urea and electrolytes, liver function tests, HbA1c, lipids, serum IGF-1, and hs-CRP. DNA methylation will be analyzed using TruDiagnostic™ to explore changes in biological age. DISCUSSION: This study aims to provide insights into the potential benefits of intermittent sirolimus (rapamycin) administration on muscle performance in older adults. By alternating periods of mTOR inhibition through rapamycin and activation via exercise, this study will explore a novel approach to enhancing muscle strength and endurance in the aging population. The results could have significant implications for developing interventions to improve physical function and overall health outcomes in older adults. Safety and tolerability will also be closely monitored to ensure the feasibility of this regimen for wider application.

Estimates suggest that only 24.9% of infants born in 2019 were exclusively breastfed before 6 months of age, despite the known health benefits of exclusive breastfeeding. Breast and nipple pain is one of the primary determinants of exclusive breastfeeding. Environmental contributions to breastfeeding success have been reported extensively in the literature, but the contribution(s) of maternal genetics has yet to be discovered. The purpose of the study was to identify an association between pain and lactation-related gene variants with exclusive breastfeeding determinants. We selected 4 genes having single nucleotide polymorphisms (SNPs) with potential functional significance in breastfeeding and pain: prolactin receptor (PRLR), oxytocin receptor (OXTR), catechol-O-methyltransferase (COMT), and milk fat globule epidermal growth factor and factor V/VIII domain containing (MFGE8). We performed a cross-sectional secondary analysis of a longitudinal randomized controlled trial study, Promoting Self-Management of Breast and Nipple Pain with Biomarkers and Technology for Breastfeeding Women (NCT05262920). Breast and nipple pain, perceived insufficient milk, and breastfeeding self-efficacy were examined using total scale scores for the Brief Pain Inventory, Visual Analog Scale, H&H Lactation Scale, and the Breastfeeding Self-efficacy Scale-short form, respectively. Of the candidate genes examined, SNPs within COMT were significantly associated with breastfeeding-related outcomes. Specifically, COMT rs4633 and rs4680 minor allele carriers (T, A) reported higher breast and nipple pain intensity than women homozygous for the major allele (C, G). COMT is the most widely researched "pain gene" and has been linked to cold, postoperative, and postpartum pain. This study is the first to identify a contribution of COMT variants to breast and nipple pain and, as a result, to breastfeeding exclusivity. PERSPECTIVE: Two SNPs in the pain gene COMT are associated with breast and nipple pain. Clinically, a minor allele in COMT rs4633 and rs4680 may increase a woman's rating of moderate breast and nipple pain. TRIAL REGISTRATION: PROMPT was registered in ClinicalTrials.gov (protocol #NCT05262920).

Purpose: To describe the breastfeeding attitudes and subjective norms of breastfeeding among African American Christians from the New England region. Study Design and Methods: A study was conducted using an online survey. Participants were recruited from four Christian churches in the New England region during the summer of 2021. Responses from direct questions about exclusive breastfeeding histories were tabulated. Open-ended question responses were analyzed using thematic analysis. Two results were merged to make the conclusions. Results: Participants (n = 101) aged 18-44 years (62.3%), college graduates (72.3%), and Catholics (71.4%) responded. Participants were willing to recommend six months of exclusive breastfeeding practice to relatives (89.9%) and friends/peers (87.9%) and support relatives (94.0%) and friends/peers (94.8%) to practice exclusive breastfeeding for 6 months. Breastfeeding attitude themes included beneficial and natural and receiving breastfeeding support. Subjective norms of breastfeeding themes included receiving support for breastfeeding; Christian leadership, teachings, and communal engagements; and gaps in Christian influence. Conclusion: The African American Christian community may be an emergent agent of breastfeeding social support for African American Christian women who chose to breastfeed. Health professionals should collaborate with African American Christian leadership to initiate programs to promote breastfeeding among African American Christian women in the United States.

Introduction: Women below the poverty threshold have lower representation and retention in breastfeeding studies. Methods: A secondary analysis of a longitudinal randomized controlled self-management for breast and nipple pain during breastfeeding study. Participants completed online surveys at discharge, weeks 1, 2, 3, 6, 9, 12, 18, and 24, with face-to-face interviews at 6 and 24 weeks. Text messages were sent to participants when modules and surveys were due. Retention was assessed in R with descriptive statistics, Mann-Whitney, Pearson's chi-square, and Cox Proportional Hazard Regression. Results: Two hundred and forty-four women (89 ≤$50,000 and 155 >$50,000) were recruited. Retention rates at 1 (93%), 2 (87%), 6 (82%), 9 (77%) and 24 (72%) weeks. For women of low income compared to those of high income there was a hazard ratio (HR) of 2.5 (p=0.0001) for retention. For non-Hispanic Black and Hispanic women compared to the combined non-Hispanic White and Other group, HRs for retention were 3.3 and 2.6 respectively (p=0.0001). Adjustment for age in the final hazard regression model of income, age, race and ethnicity decreased the HR for women of low income to 1.6 and HRs for non-Hispanic Black and Hispanic women to 2.1 and 1.9, respectively (p=.0001). However, none of the individual factors in the model achieved statistical significance. Discussion: Retention in breastfeeding studies impacts breastfeeding duration, a key lifelong preventative health behavior. Despite accessible study design, retention of women desiring to breastfeed was adversely affected by the intersection of income, race and ethnicity, and age.
RESUMO
Background: In United States, African American women are the least likely group to breastfeed exclusively compared with Hispanic and non-Hispanic white women. It is crucial to examine the perceived confidence of African American women towards practicing exclusive breastfeeding. Previous studies have examined breastfeeding self-efficacy and other factors influencing exclusive breastfeeding. However, there is no research on exclusive breastfeeding self-efficacy of this population. The purpose of this study was to examine the validity and reliability of the breastfeeding self-efficacy scale to measure exclusive breastfeeding, and the relationship between exclusive breastfeeding self-efficacy and general self-efficacy and demographic variables in African American women. Methods: Descriptive cross-sectional design was used. A convenience sample of 53 pregnant African American women completed an online survey. Construct and criterion-related validity were assessed and reliability of the breastfeeding self-efficacy scale to measure exclusive breastfeeding (BSES-EBF) was examined using Cronbach's reliability. The general self-efficacy scale measured general self-efficacy. Descriptive statistics, bivariate correlation and non-parametric analyses were performed using statistical package for social sciences (v.28). Results: The breastfeeding self-efficacy to measure exclusive breastfeeding scale had a Cronbach's alpha score of 0.907. One principal component was extracted from the BSES-EBF scale, with an Eigenvalue of 5.271 and which explained 58.57% of the variance in the instrument. The mean prenatal exclusive breastfeeding self-efficacy of participants was 35.15 (±7.41) from a range of 9 to 45. Exclusive breastfeeding was significantly associated with general self-efficacy (r = 0.503, p ≤ 0.001) and exclusive breastfeeding intention (p = 0.034). Conclusion: Breastfeeding self-efficacy scale to measure exclusive breastfeeding is a valid and reliable tool to measure exclusive breastfeeding self-efficacy in African American women. African American women had high exclusive breastfeeding self-efficacy (internal motivation). Hence, there is a need to address breastfeeding barriers and provide access to culturally sensitive support (external motivation) to increase exclusive breastfeeding in African American women.
