Determinants of short birth interval in Ethiopia: A multilevel analysis based on EDHS 2019, Ethiopia, 2023.

According to the World Health Organization and Ethiopian Demographic and Health Survey on birth spacing, there should be at least a two-year gap between conception and the first of two children born in quick succession. In poor nations like Ethiopia, resource issues were complex, making it difficult to get statistics for the entire country. However, by examining Ethiopian mini demographic and health survey data, we were able to provide data at the national level. The cross-sectional survey-based study was conducted in several of Ethiopia's administrative cities and nine regions. In the analysis, sampling weight was used to correct the survey's non-proportional sample distribution to strata and areas throughout the survey process and restore representative data. The study's household population was presented and described using descriptive statistics such as weighted frequencies and percentages. The statistically significant factors linked to frequent short birth intervals were found using a multivariable, multilevel logistic regression analysis. Overall, 4306 weighted multigravida mothers nested within 305 enumeration areas were included in the analysis. The respondents' mean (standard deviation) of the birth interval was 42.027(26.69). Higher-educated women had 12% lower odds of having a shorter pregnancy (AOR = 0.88; 95% CI: 0.35, 0.98) than women without higher education. The odds of a short birth interval were 3.04 times greater among women in the age category of 40-49 years at first marriage (AOR = 3.04; 95% CI: 1.08, 8.46) than among women in the age category of 15-19 years. This indicates that older women were most likely to have short birth intervals. In the multilevel logistic regression model, maternal age, maternal educational status, the wealth quintile index, use of contraceptives, duration of breastfeeding, and contextual regions were significantly associated with short birth intervals in Ethiopia.

Process evaluation of a breastfeeding support intervention to promote exclusive breastfeeding and reduce social inequity: a mixed-methods study in a cluster-randomised trial

BackgroundBreastfeeding is a powerful public health intervention that produces long-term health benefits. However, in high-income countries such as Denmark, breastfeeding rates are suboptimal and unequally distributed across socio-economic positions. The ‘Breastfeeding – a good start together’ intervention, to promote longer duration of exclusive breastfeeding and reduce social inequity, was implemented in a cluster-randomised trial during 2022–2023 across 21 municipalities in two Danish regions. A process evaluation was conducted to assess the implementation, mechanisms of impact, and possible contextual factors affecting the intervention.MethodsThe study was guided by the Medical Research Council’s guidance for conducting process evaluations and employed a mixed-methods approach in a convergence design. Quantitative data: contextual mapping survey (n = 20), health visitor survey (n = 284), health visitor records from 20 clusters and intervention website statistics. Qualitative data: dialogue meetings (n = 7), focus groups (n = 3) and interviews (n = 8).ResultsOverall, the intervention was delivered as planned to intended recipients, with few exceptions. Health visitors responded positively to the intervention, noting that it fitted well within their usual practice and enhanced families’ chances of breastfeeding. Mothers expressed having received the intervention with few exceptions, and reacted positively to the intervention. Although health visitors were concerned about the potential stigmatisation of mothers receiving the intensified intervention, none of the interviewed mothers felt stigmatised. Contextual factors impacting the intervention implementation and mechanisms included staff and management turnover, project infrastructure and mothers’ context, such as resources, social networks and previous experiences. The overall fidelity of the intervention delivery was high.ConclusionsHealth visitors and families responded well to the intervention. Interventions aimed at enabling health care providers to deliver simplified and structured breastfeeding support, in alignment with support provided in other sectors of the health care system, may increase breastfeeding rates and reduce social inequity in breastfeeding, even in international contexts.Trial registrationClinical Trials: NCT05311631.

Breastfeeding During COVID-19 Stay-at-Home Orders: Implications for Future Maternal Work Policies and Health Equity.

This study aimed to explore the impact of the COVID-19 pandemic and associated stay-at-home orders on the breastfeeding experiences of U.S. people a identify facilitators and barriers to breastfeeding during this period, and to assess the effects of maternal stress and misinformation on breastfeeding practices. U.S. women with infants were selected through purposive and convenience sampling. An online survey, distributed during summer 2020, measured changes in infant feeding practices, maternal stress levels, use of lactation support resources, and the influence of misinformation on feeding decisions. Quantitative data were analyzed using descriptive statistics, and qualitative responses underwent thematic analysis. Our sample (n = 1,861) revealed that 34% of U.S. women realized the pandemic affected their feeding practices, 544 women provided qualitative data. Major themes from qualitative analysis included ease of breastfeeding at home, bonding, increased breastfeeding duration, and challenges like limited access to lactation support. Logistic regressions highlighted demographic influences on breastfeeding practices, with no significant effects found related to the child's age or women's income on changes in feeding practices. The COVID-19 pandemic substantially impacted breastfeeding experiences of U.S. women, yielding insights for future policy and healthcare practices. The findings underscore the potential benefits of telehealth lactation support services and flexible remote work environments for breastfeeding people. Clear and scientifically-grounded communication regarding breastfeeding, mental health support, and policy development, are essential to promote equitable and flexible work and maternity leave options for breastfeeding people especially during global health crises.

Differences in Breastfeeding Initiation and Duration by Migration History in the Hispanic Community Health Study/Study of Latinos.

Objective: To estimate differences in breastfeeding initiation and duration across dimensions of migration history (migration to the U.S. 50 states/District of Columbia [DC] in childhood, adulthood, or not at all) in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Methods: We used data from HCHS/SOL on 520 individuals with a post-baseline live birth and information on breastfeeding collected at Visit 2 (2014-2017). We fit log binomial models adjusted for parity, age at pregnancy, education, income, and immigration history and incorporating sampling weights. Results: Overall, 84% of participants reported initiating breastfeeding and 30% reported breastfeeding for 6 or more months. On average, individuals reported breastfeeding for a median of 88 days (interquartile range: 156). Compared with those born in the U.S. 50 states/DC, individuals born in another country or U.S. territory who arrived in the U.S. 50 states/DC as children (<18 years old) were 2.7 times more likely to initiate breastfeeding (adjusted prevalence ratio 2.7, 95% confidence interval [CI]: 1.4, 4.9) and those who arrived as adults were 2 times more likely to initiate breastfeeding (adjusted prevalence ratio 2.0, 95% CI: 1.1, 3.6). We observed similar patterns for breastfeeding continuation. Conclusions: The timing and duration of life course experiences such as migration are key determinants of breastfeeding behavior among Hispanic/Latina postpartum persons.

Patterns of complementary feeding introduction and associated factors in a cohort of Brazilian infants

BackgroundUnderstanding the timing of food introduction in infants is essential for promoting optimal complementary feeding practices. However, existing studies often rely on cross-sectional data, limiting the ability to capture age-specific patterns. We aimed to describe food introduction during the first year of life by identifying patterns related to age at food introduction and associated factors in a cohort of Brazilian infants.MethodsData were collected through standardized questionnaires administered to mothers via face-to-face interviews during the infant’s first month of life and at 3, 6, 9, and 12 months of age. Additionally, two telephone interviews were conducted at 2 and 4 months of age. Information regarding food intake was assessed using a list of 48 foods, with two key aspects recorded: whether the food was introduced (yes/no) and the age at introduction. To define food introduction patterns, we employed k-means cluster analysis. Hierarchical Poisson multiple regression was employed to examine the associations between sociodemographic, biological, and healthcare factors and patterns of food introduction.ResultsThree distinct patterns were identified and named according to their main characteristics: Pattern 1 – “Low Infant Formula and Timely CF Introduction”; Pattern 2 – “High Infant Formula and Early CF Introduction”; and Pattern 3 – “High Infant Formula and Later Ultra-processed Food Introduction”. Breastfeeding at six months showed a positive association with Pattern 1 (PR = 1.40; 95% CI = 1.10–1.80), while bottle use at four months was negatively associated with Pattern 1 (PR = 0.68; 95% CI = 0.53–0.87). No variables studied exhibited an association with Pattern 2. For Pattern 3, higher prevalences were observed among children whose mothers were aged < 20 years (PR = 1.54; 95% CI = 1.13–2.01) or > 34 years (PR = 1.42; 95% CI = 1.04–1.93). Not receiving guidance on the recommended duration of breastfeeding and complementary feeding during prenatal care was associated with a higher prevalence of children in this pattern (PR = 1.35; 95% CI = 1.01–1.80).ConclusionsWe identified three distinct patterns of age at food introduction in the study population, although none perfectly aligned with Brazilian or WHO dietary recommendations. These findings underscore the need for targeted interventions to promote timely and healthy complementary feeding practices in Brazilian infants.

Development of a complex intervention to strengthen municipality-based breastfeeding support to reduced social inequity in breastfeeding

BackgroundBreastfeeding is the ideal nutrition for infants and protects infants and mothers from a range of adverse health outcomes during their lifespan. In Denmark, while the breastfeeding initiation rate is high, only 14% of mothers meet the World Health Organization’s recommendation of exclusive breastfeeding at six months. Furthermore, a notable social inequity exists among those who achieve this recommendation. Knowledge of effective interventions to reduce breastfeeding inequity is limited. A previous hospital-based intervention succeeded in increasing breastfeeding duration. However, most breastfeeding support is provided in Danish municipalities by health visitors. This called for adapting the intervention to the health visiting program and developing an intensified intervention addressing the social inequity in breastfeeding. This article describes the adaptation and development process of a municipality-based intervention.MethodsDuring a 15-month period in 2020–21, the municipal intervention was iteratively developed using a three-stage framework for developing complex health interventions described by Hawkins et al. The three stages were 1) need assessment and stakeholder consultation, 2) co-production and 3) prototyping. The process was inspired by O’Cathain et al.’s principles for a user-centred, co-created and theory- and evidence-based approach, involving parents and health visitors.ResultsIn stage 1, we identified the needs and priorities of the target groups of the intervention. In stage 2, the intervention was developed through action research design and inspired by Duus’ ‘learning cycles’ as the method to enhance motivation and ownership and to strengthen the implementation process by creating a joint room for learning and reflection with health visitors and developers. In stage 3, the intervention was tested for feasibility and usefulness during a 2.5-month period accompanied by monthly dialogue meetings with health visitors and developers. In this period, the intervention was refined based on the gathered experiences and was subsequently prepared for evaluation.ConclusionThe description of the development of this complex intervention, aimed at increasing breastfeeding duration and reducing inequity, offers breastfeeding practitioners and researchers a transparent foundation for continuously improving breastfeeding support and a methodology for complex intervention development.Trial registrationRegistered at Clinical Trials NCT05311631.

Epigenetic and Immune Mechanisms Linking Breastfeeding to Lower Breast Cancer Rates.

This review shows how mammary stem cells (MaSCs) influence breast development, breastfeeding, and breast cancer risk. MaSCs, which can differentiate into various cell types, are vital for breast tissue health, but also disease development in breast tissue. Research shows that breastfeeding affects MaSCs, offering protection against breast cancer through various mechanisms. Hormonal changes such as increased prolactin concentration, oxytocin secretion, lower progesterone levels, and reduced exposure to estrogen during lactation promote apoptosis in potential cancer cells, boost immune surveillance, and modulate inflammation. Key findings reveal that pregnancy at an earlier age and extended breastfeeding reduce MaSC numbers, lowering cancer risk. Additionally, breastfeeding induces various epigenetic changes, such as DNA methylation and histone modification, which provide long-term protection against the development of cancer. Components of breast milk, like alpha-lactalbumin and lactoferrin, contribute by promoting cancer cell apoptosis and inhibiting tumor growth. The dual benefits of breastfeeding are reduced breast cancer risk for mothers and immunological advantages for infants. Multicenter epidemiology research has focused particular attention on longer breastfeeding duration associated with a reduced risk of triple-negative breast cancer. This review offers comprehensive evidence that breastfeeding protects against breast cancer through various biological, hormonal, and molecular mechanisms, showing the importance of promoting breastfeeding as a natural cancer prevention method. This article reviews the role of mammary stem cells in breast development, lactation, and breast cancer.

Reproductive factors and mammographic density within the International Consortium of Mammographic Density: A cross-sectional study

BackgroundElevated mammographic density (MD) for a woman’s age and body mass index (BMI) is an established breast cancer risk factor. The relationship of parity, age at first birth, and breastfeeding with MD is less clear. We examined the associations of these factors with MD within the International Consortium of Mammographic Density (ICMD).MethodsICMD is a consortium of 27 studies with pooled individual-level epidemiological and MD data from 11,755 women without breast cancer aged 35–85 years from 22 countries, capturing 40 country-& ethnicity-specific population groups. MD was measured using the area-based tool Cumulus. Meta-analyses across population groups and pooled analyses were used to examine linear regression associations of square-root (√) transformed MD measures (percent MD (PMD), dense area (DA), and non-dense area (NDA)) with parity, age at first birth, ever/never breastfed and lifetime breastfeeding duration. Models were adjusted for age at mammogram, age at menarche, BMI, menopausal status, use of hormone replacement therapy, calibration method, mammogram view and reader, and parity and age at first birth when not the association of interest.ResultsAmong 10,988 women included in these analyses, 90.1% (n = 9,895) were parous, of whom 13% (n = 1,286) had ≥ five births. The mean age at first birth was 24.3 years (Standard deviation = 5.1). Increasing parity (per birth) was inversely associated with √PMD (β: − 0.05, 95% confidence interval (CI): − 0.07, − 0.03) and √DA (β: − 0.08, 95% CI: − 0.12, − 0.05) with this trend evident until at least nine births. Women who were older at first birth (per five-year increase) had higher √PMD (β:0.06, 95% CI:0.03, 0.10) and √DA (β:0.06, 95% CI:0.02, 0.10), and lower √NDA (β: − 0.06, 95% CI: − 0.11, − 0.01). In stratified analyses, this association was only evident in women who were post-menopausal at MD assessment. Among parous women, no associations were found between ever/never breastfed or lifetime breastfeeding duration (per six-month increase) and √MD.ConclusionsAssociations with higher parity and older age at first birth with √MD were consistent with the direction of their respective associations with breast cancer risk. Further research is needed to understand reproductive factor-related differences in the composition of breast tissue and their associations with breast cancer risk.

Prenatal Breastfeeding Education with or without Hand Expressing Human Milk and Breastfeeding Duration in a Rural Population.

The benefits of breastfeeding are well recognized. However, exclusive breastfeeding (EBF) rates are well below the Healthy People 2030 Guidelines, with a rapid drop in exclusive breastfeeding over the first 3 months of life. Although breastfeeding support has increased the initiation of breastfeeding, the role of perinatal interventions, particularly in the context of breastfeeding support, remains a topic of contradiction. This observational study was designed to assess the impact of a unique prenatal educational intervention in rural East Texas. The study had two aims: (1) to determine whether the addition of prenatal breastfeeding education increased the rate of exclusive breastfeeding at four time points, and (2) to assess the impact of hand expression education on breastfeeding exclusivity. Differences in breastfeeding behaviors were seen between those who received the education and those who did not for exclusivity and duration of breastfeeding. Participants who received the hand expression education were 1.79 times more likely to continue EBF practices at three months postpartum, 6.27 times more likely to continue EBF practices at six months postpartum, and 3.34 times more likely to continue breastfeeding at twelve months postpartum than those who did not receive any hand expression education. This study demonstrates that prenatal education is beneficial for increasing breastfeeding exclusivity and duration and underscores its potential to improve maternal and infant health outcomes. Further research is needed to resolve the ongoing debate and advance our understanding of interventions to increase breastfeeding duration.

The Effect Of Prepregnancy Bmi And Parity On The Duration Of Breastfeeding During Exclusive Breastfeeding

Obesity Is a condition in a person who experiences overnutrition, Especially Fat Accumulation, Which cause the body to weight more than normal body weight, Indicated with A Body Mass Index (BMI) of more than 29.9 kg/M2 several International Pieces Of Research State That Obese Mothers Fail To Breastfeed Exclusively. Aside From Maternal BMI, Maternal Characteristics Also Support Exclusive Breastfeeding. Maternal Characteristic Factors Include Age, Parity, And Mother’s Education. This Study Aims To Determine The Correlation Between Prepregnancy BMI And Maternal Characteristic Factors With The Duration Of Breastfeeding During Exclusive Breastfeeding. This Research Is Quantitative Research Using A Cross-Sectional Descriptive-Correlational Method With A Retrospective Approach. The Number Of Samples In This Research Was 300 Mothers Who Met The Inclusion Criteria With The Purposive Sampling Technique. Data were collected and processed statistically using the Chi-Square Test and T-test to determine factors related to breastfeeding duration, and the linear regression test with the backward method was used to determine the most influential factors in breastfeeding.The Chi-Square Test Results Showed That All Variables Were Related To The Duration Of Breastfeeding With A P-value &lt;0.05. The Linear Regression Test Showed That The Factors That Had A Significant Effect On The Duration Of Breastfeeding Were Prepregnancy BMI And Parity With A Significance Of 0.00; judging From The Coefficient B Factor Value Of 0.285, Parity Had A More Dominant Effect.

Undernutrition and its determinants among children aged 6–59 months in Southern Ethiopia

Malnutrition is responsible for over one-third of deaths among children under the age of five in low-and middle-income countries, including Ethiopia, and is largely preventable. The objective of this study was to determine the prevalence of undernutrition and its contributing factors among children aged 6–59 months in the Gedio zone of Southern Ethiopia. A community-based cross-sectional study design was used, and data were collected from 403 children and their mothers selected through random sampling technique. Anthropometric measures were converted to Z-scores using WHO-Anthro version 3.2.2 software. The prevalence of underweight, wasting, and stunting were 19.7% (95% CI 16-24%), 10% (95% CI 7–13%), and 49% (95% CI 44–54%) respectively. Low birth weight (AOR = 2.8, 95% CI (1.585–4.895), feeding non-diversified diet (AOR = 1.9, 95% CI (1.036–3.497), and being unvaccinated (AOR: 2.0; 95%CI (1.013–4.197) were significantly associated with being underweight. Family size of ≥ 5 (AOR = 4.4, CI (1.274–5.059), meal frequency of < 3 times per a day (AOR = 2.3, CI (1.037–5.024), and index birth interval of < 24 months (AOR = 2.2, CI (1.015–4.843) were significantly associated with wasting. Similarly, children aged ≥ 24 months (AOR = 2.8, CI (1.769–4.474), feeding non-diversified diet (AOR = 1.8, CI (1.153–2.894), total duration of breast-feeding < 12 months (AOR = 4.0, CI (2.547–6.429), and mothers BMI below 18.5 (AOR = 2.2, CI (1.328–3.718) were identified as a predictors of stunting. The study revealed significant levels of undernutrition, including underweight, wasting, and stunting, among children in the study area. Factors such as birth weight, dietary diversity score, and vaccine status were found to be strongly linked to underweight. Additionally, living in a large family, meal frequency, and birth interval were significantly associated with wasting. The age of the child, duration of breastfeeding, dietary diversity score, and maternal BMI status were also significantly linked to stunting. To address this issue, the study recommends promoting healthier feeding practices, dietary diversification, optimal breastfeeding, complete vaccination, wider birth intervals, and improving maternal nutrition to reduce undernutrition among children aged 6–59 months in the area. Implementing these measures could significantly improve the health of children in the study area.

Increased Cadmium Load, Vitamin D Deficiency, and Elevated FGF23 Levels as Pathophysiological Factors Potentially Linked to the Onset of Acute Lymphoblastic Leukemia: A Review.

The preventability of acute lymphocytic leukemia during childhood is currently receiving great attention, as it is one of the most common cancers in children. Among the known risk factors so far are those affecting the development of gut microbiota, such as a short duration or absence of breastfeeding, cesarean section, a diet lacking in short-chain fatty acids (SCFAs), the use of antibiotics, absence of infection during infancy, and lack of pets, among other factors. Namely, it has been shown that iron deficiency anemia (IDA) and lack of vitamin D may cause intestinal dysbiosis, while at the same time, both increase the risk of hematological malignancies. The presence of IDA and vitamin D deficiency have been shown to lead to a decreased proportion of Firmicutes in stool, which could, as a consequence, lead to a deficit of butyrate. Moreover, children with IDA have increased blood concentrations of cadmium, which induces systemic inflammation and is linked to the onset of an inflammatory microenvironment in the bone marrow. Finally, IDA and Cd exposure increase fibroblast growth factor 23 (FGF23) blood levels, which in turn suppresses vitamin D synthesis. A lack of vitamin D has been associated with a higher risk of ALL onset. In brief, as presented in this review, there are three independent ways in which IDA increases the risk of acute lymphocytic leukemia (ALL) appearance. These are: intestinal dysbiosis, disruption of vitamin D synthesis, and an increased Cd load, which has been linked to systemic inflammation. All of the aforementioned factors could generate the appearance of a second mutation, such as ETV6/RUNX1 (TEL-AML), leading to mutation homozygosity and the onset of disease. ALL has been observed in both IDA and thalassemia. However, as IDA is the most common type of anemia and the majority of published data pertains to it, we will focus on IDA in this review.

The Lack of an Association of Breastfeeding with the Development of Childhood Intussusception: A Nationwide Birth Cohort Survey in Japan.

Background: This study investigated the association between feeding practices and the development of childhood intussusception. Materials and Methods: We conducted secondary data analyses using the Longitudinal Survey of Newborns in the 21st Century in Japan. We performed multivariable logistic regression analyses to examine the association between feeding practice and intussusception development in children aged between 6 and 18 months. We used the following variables as potential confounders: gender, gestational age, birth weight, singleton or multiple births, parity, maternal age at delivery, maternal smoking status, and paternal smoking status. Furthermore, we performed multivariable logistic regression analyses to examine the association between breastfeeding duration and intussusception development. Results: In total, 31,802 children were analyzed in this study. The annual incidence of intussusception was 1.6 cases per 1,000 children aged between 6 and 18 months. No significant association was found between exclusive breastfeeding and the development of intussusception, compared with exclusive formula feeding (odds ratio, 1.64; 95% confidence interval, 0.32-30.0). Furthermore, no significant association was observed between breastfeeding duration and intussusception development. Conclusions: Our findings demonstrated no association between breastfeeding and the development of childhood intussusception.

Does Breast Feeding Protect Mothers From Obesity?

Hepatosteatosis, which we frequently observe today with change in lifestyle, is often unnoticed, but preventable and reversible; if not prevented, it can lead to serious comorbidities. There is contradicting evidence in the literature; we believe that breastfeeding has a protective effect on hepatosteatosis. In this cross-sectional study we conducted, we aimed to examine the relationship between breastfeeding duration, metabolic parameters and fatty liver. We examined the data of 135 patients aged 20-40 years who have had at least one pregnancy and were admitted to our polyclinic. Forty-five healthcare staff who never breastfed were included in the control group. Measurements of height and weight were taken, and number of children and total breastfeeding time were questioned. Blood values were measured to calculate insulin resistance, non-alcoholic fatty liver disease (NAFLD) fibrosis score and Fibrosis-4 (FIB-4) score. Consequently, there was no significant correlation between total breastfeeding time and body mass index (BMI), NAFLD fibrosis score, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) value and hemoglobin A1C (HbA1C). When two groups were formed as patients breastfeeding for less than six months and patients breastfeeding for more than six months, a significant difference in BMI was observed between these two groups (p: 0.02). There was a significant relationship between BMI and NAFLD (p: 0.00) and HOMA-IR (p: 0.00). It was observed that there was a significant difference between BMI FIB-4 and NAFLD fibrosis scores of the control group and breastfed group. Lactation should be maintained for at least six months for maternal health together with the baby's health, and more comprehensive studies should be conducted for long-term data.

Impact of Maternal Body Composition, Hydration, and Metabolic Health on Breastfeeding Success: A Comprehensive Review.

It is well established that breastfeeding provides significant health benefits for both the mother and the infant. The World Health Organization recommends initiating breastfeeding within the first hour after birth and continuing exclusive breastfeeding for 6 months. Successful breastfeeding is influenced not only by the proper physiological preparation of the body and the action of pregnancy-related hormones but also by the mother's overall health status. However, the role of maternal body composition and metabolic condition in breastfeeding success has received little attention. To better understand the impact of these factors on breastfeeding effectiveness, we reviewed the latest research on this topic, with particular emphasis on the role of hydration and lipid metabolism. Our narrative review indicates that the amount and distribution of water and adipose tissue are crucial for successful lactation and that various hormonal imbalances and metabolic disorders increase the risk of delayed breastfeeding initiation, shortened breastfeeding duration, or insufficient milk production. In light of our findings, measurement methods for assessing described parameters were also introduced. This article aims to review the effects of maternal body composition, hydration status, and metabolic and social factors on lactation and breastfeeding.

Factors Influence Breastfeeding Duration after High Risk and Low Risk Pregnancies.

Breastfeeding provides vital nutrients and fosters maternal-infant bonding, benefiting both mother and child. However, breastfeeding duration is influenced by various factors, especially in women of high-risk pregnancy. This study aims to identify predictors of breastfeeding duration among women of high-risk and low-risk pregnancy, focusing on exclusive and mixed feeding practices. Conducted at a public hospital in Attica, Greece, this 20-month prospective cohort study (May 2020-January 2022) included 380 pregnant women, divided into high-risk and low-risk groups. The final sample of 157 women, after excluding non-breastfeeding participants, was assessed across five phases from prenatal to six months postpartum using interviews, calls, and surveys. Multiple linear regression identified key predictors, with statistical methods applied. Results revealed birth weight as a consistent significant predictor of breastfeeding duration. For women with high-risk pregnancy, additional factors like infant gender, jaundice, and early introduction of solid foods influenced breastfeeding duration. The mixed breastfeeding model for women with high-risk pregnancy explained 72.9% of the variance. Exclusive and mixed breastfeeding models for women with low-risk pregnancy also highlighted birth weight's influence. The findings highlight the important role of birth weight and other specific factors in determining breastfeeding duration among women of high-risk and low-risk pregnancy. Further research is needed to validate these findings across diverse populations.

Abstract A014: Racial and socioeconomic disparities in breast feeding and the impact of pregnancy-related medical conditions among a population-based sample of non-Hispanic Black and White women

Abstract Background: Breastfeeding has been associated with a reduced risk of breast cancer (BC), particularly with Triple Negative BC (TNBC). The risk of TNBC is higher among premenopausal women, Black/African American (AA) women, and poorer women. Notably there are significant disparities in breastfeeding, where non-Hispanic Black (NHB) women and poorer women are less likely to breastfeed in the United States. Studies have identified historical racial trauma, unsupportive work and hospital policies, breast milk formula advertising, and knowledge and beliefs about breast feeding as factors that contribute to breast feeding practices. However, there is a paucity of research on pregnancy related medical conditions (PMCs) that potentially impact initiation and duration of breastfeeding. The purpose of this study is to evaluate racial and socioeconomic differences in breastfeeding, and if PMCs impact breastfeeding practices in a population-based sample of non-Hispanic Black and White women. Method: Data are from the Young Women’s History and Health Study (YWHHS), a population- based case-control study of invasive BC among non-Hispanic Black (NHB) and non-Hispanic White (NHW) women aged 20-49 years residing in Metropolitan Detroit and Los Angeles County, 2010-2015. The analytic sample here includes the first pregnancy of control participants with singleton live births (n=675). Area-based control participants were sampled from the 2010 Census. Interviews assessed complete reproductive histories, including breastfeeding history (never, &amp;lt;6 months, and ≥6 months), PMCs experienced during pregnancy, self-reported race, and household financial struggles before age 13 years (to approximate childhood socioeconomic position (chSEP)). PMCs examined included: 1) premature birth, 2) diabetes or pre-diabetes related PMCs, 3) blood pressure-related PMCs, and 4) BMI ≥ 25 kg/m2 at age 18 years. Weighted percentages were evaluated with a chi-square test and considered significant at p &amp;lt; 0.05. Analyses were further stratified by race/ethnicity and chSEP. Result: NHB women were 2.4 times significantly more likely to never breastfeed than NHW women (W% =52.0 (NHB) and 21.3 (NHW), p=&amp;lt;0.0001). Similarly, women with lower compared to higher chSEP were 1.5 times significantly more likely to never breastfeed (W% = 42.7 (lower chSEP) and 28.5 (higher chSEP), p=0.003). Those with BMI ≥ 25 kg/m2 at age 18 years (p&amp;lt;0.001) alone, and with one or more PMCs (p=0.01) were also less likely to breastfeed. When stratified by race/ethnicity the pattern of breastfeeding did not differ significantly by any PMC within NHB and NHW women. When stratified by chSEP, however, BMI ≥ 25 kg/m2 at age 18 years (p = 0.004) and having one or more PMCs (p=0.03) were significantly associated with never breastfeeding among those with higher chSEP. Conclusion: NHB women and women with lower chSEP were substantially less likely to breastfeed. Additionally, BMI ≥ 25 kg/m2 at age 18 and PMCs were associated with lower frequency of breastfeeding overall and among those with higher chSEP. Citation Format: Meheret B. Gebreegziabher, Lydia R.

Abstract B070: Addressing health disparities around breastfeeding: Development of a braided curriculum

Abstract Purpose: Breastfeeding initiation and longer duration are known to reduce risk of breast and ovarian cancer. While racial disparities in breast cancer diagnosis and mortality rates exist in the United States, disparate rates of breastfeeding initiation and duration continue to widen. The positive effects of these community lactation support through peer education programs among Black mothers have been demonstrated, but these programs are limited by the lack of reach to vulnerable families. Integration of lactation education and support within parenting programs targeting complementary maternal behaviors, such as psychosocial stress does not exist. This proof-of-concept study uses novel Systematic Braiding methodology to develop an integrated maternal behavior parenting curriculum. Methods: In line with the systematic braiding technique, key stakeholders of two evidence based programs, Intergen (a culturally competent breastfeeding peer-educator program) and SafeCare® (a widely disseminated evidence-based parenting program), were consulted to identify core program components, shared and unique theoretical constructs, and programmatic targets including: population of interest, behaviors, delivery mode, program content, dose and length, assessment, fidelity monitoring. Results: 10 program developers and content experts identified shared and unique theoretical constructs and programmatic targets including: population of interest – at-risk minority parents, behaviors (parenting, breastfeeding, and cancer prevention), delivery mode (in person and self-guided), program content, dose and length, assessment, and fidelity monitoring. Areas of integration were captured to inform the braiding of the new curriculum based in social cognitive theory and the theory of planned behavior including modules on cancer education, prevention through breastfeeding, and screening were captured to inform the braiding of the new curriculum. Future directions will assess the acceptability and feasibility of the braided curriculum via user-centered feedback across informants from each of four key informant groups: 1) target recipients of the curriculum including Black women, &amp;lt;36 weeks gestation; 2) potential program providers; 3) community health care professionals; and 4) state-level legislative representatives. Interim findings will be presented. Discussion: There is limited exploration on using widely disseminated parenting programs to increase breastfeeding uptake among African American mothers. This study takes first steps towards developing a robust intervention to increase the reach of breastfeeding education to expecting African American mothers through a widely disseminated parenting model. Improving knowledge of cancer prevention through breastfeeding along with behavior (initiation and duration) among this at-risk population may positively impact breast and ovarian cancer risk.

Abstract B071: Mothers Informed Lactation Knowledge and Support (MILKS): Addressing Cancer Disparities through Community Action

Abstract Purpose: The Mothers Informed Lactation Knowledge and Support (MILKS) project aims to increase breastfeeding initiation and duration in Aiken County, South Carolina, specifically among Black/African American (B/AA) and Hispanic women. Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer death from 2012-2016 in this county. Methods: In collaboration with the Aiken Maternal Health Workgroup, a community health needs assessment was conducted. Listening sessions, health data review, and an environmental scan were conducted. A community report card was developed to disseminate and identify intervention needs. Areas assessed include: knowledge of cancer prevention, breastfeeding resources, lactation consultant/peer educators, breastfeeding friendly employers, and community support. Results: Aiken Co. has a total population of 174,150, 37% of the population lives in rural areas, 24.7% are non-Hispanic B/AA, 6.3% are Hispanic, and 12% of the population is uninsured. The breastfeeding initiation rate is 77.2 % (64.3%, B/AA and 86.7% Hispanic), compared to 78.5 percent for South Carolina and 83.2 percent for the United States. Breast cancer 5-year incidence rate all women is similar between Aiken (124) and South Carolina (129) /100,000, and breast cancer mortality rate is higher in Aiken (25) vs. SC (22) / 100,000 age-adjusted population. B/AA women have a significantly higher rate of breast cancer incidence (98.0) and mortality (37.8)/100,000 than state and national averages. There is an inappropriate number of lactation consultants and peer educators – only 1 is available to a limited population in-person, 2 are available to WIC recipients virtually. The WIC office also has two peer counselor positions, both of which were vacant at the time of research. Community listening sessions (n=4) provided insight into language and cultural barriers in accessing breastfeeding resources. Specifically, Hispanic women expressed difficulties in finding culturally relevant information and assistance. Participants highlighted the importance of education, advocating for improved workplace accommodations, such as designated lactation spaces and flexible scheduling, to enable breastfeeding mothers to manage the challenges of returning to work while continuing to breastfeed. No one reported previous knowledge of cancer prevention through breastfeeding. A lack of social norms for breastfeeding was also identified. Conclusions: Recommendations based on the report card include expanding peer education programs, enhancing workplace support, and ensuring cultural and linguistic inclusivity in breastfeeding education and support, and cancer prevention resources. The next steps include implementing additional peer education programs in the community, with a focus on cancer prevention through education, screening, and community support. This project provides a replicable blueprint for addressing cancer disparity through community engagement and collaboration.

Breastfeeding mothers' self-confidence: A mixed-method study

Objective: To establish the association of the mother's breastfeeding self-efficacy with infant feeding in the first six months of the child's life and identify the mothers’ perception of their confidence to breastfeed. Background: Breastfeeding is a multi-determined process. Many factors contribute to a mother’s ability to exclusively breastfeed until a child reaches six months of age. Among these factors is a mother’s confidence in her abilities to breastfeed her baby, referred to as breastfeeding self-efficacy. Thus, self-efficacy for breastfeeding could be an essential predictor of reducing the risk of early weaning. Study design and methods: This is a mixed-method sequential explanatory study. The short form of the Breastfeeding Self-Efficacy Scale was used to determine the level of the mothers' confidence. 158 mothers were surveyed during their postpartum hospital stay, and 128 were included in a follow-up six months after delivery. Additionally, 22 participants were randomly selected for an in-depth interview (qualitative stage). Data were analysed using inferential statistics and thematic content analysis. Results: High levels of breastfeeding efficacy were identified during the hospitalisation and after discharge among all participants. Exclusive breastfeeding was practised among 45.31% of mothers six months after delivery. Return to work was a key factor contributing to early weaning. Family and health professional support during the breastfeeding process were associated as crucial for the duration of exclusive breastfeeding. Discussion: Exclusive breastfeeding for the first six months after delivery involves various factors, such as the mother’s confidence in her breastfeeding skills and the specific circumstances she faces while breastfeeding. Thus, through the mixed qualitative and quantitative approaches, it was possible to identify the convergence of self-efficacy scores and the breastfeeding mothers' perception of their confidence and intention to maintain exclusive breastfeeding. Conclusion: High self-efficacy to breastfeed alone was not enough to maintain exclusive breastfeeding. It is necessary to combine self-efficacy and family or health service support and guidance to clarify the mother's doubts about potential difficulties that may appear throughout the breastfeeding process, the maintenance of lactation when she plans to return to work, and the breastfeeding technique. Implication for practice: Applying the Breastfeeding Self-Efficacy Scale associated with the breastfeeding mothers' interview during the prenatal and perinatal period facilitates early identification of mothers at risk for early weaning and helps nurses in planning interventions to support the breastfeeding mother and her child in favour of exclusive breastfeeding duration. What is already known about the topic? Exclusive breastfeeding (EBF) is recommended for the first six months of a child's life; however, many mothers do not follow this recommendation due to multiple barriers such as mental health issues (i.e., postpartum depression or anxiety), educational gaps, physical discomfort like sore nipples, engorgement, return to work, and lack of support. Breastfeeding self-efficacy has been associated with the duration of breastfeeding. What this paper adds Breastfeeding mothers' self-efficacy is essential for stimulating maintenance. Questions 3 (I always feed my baby without using powdered milk as a supplement) and 11 (I always breastfeed my baby on one breast and then switch to the other) of the Breastfeeding Self-Efficacy Scale (short form) predicted early weaning risk. Planning nursing care intervention for breastfeeding mothers in their follow-up after birth should include assessing their breastfeeding self-efficacy and factors that could contribute to early weaning, such as returning to work and the lack of a support network.
