Breastfeeding and maternal cardiovascular risk factors and outcomes: A systematic review

Breastfeeding duration is associated with favorable body composition and lower glycoprotein acetyls in later life

OBJECTIVE

The aim of the present study was to investigate associations between lifetime breastfeeding behaviors and cardiovascular risk in later reproductive years.

METHOD

This was a prospective 10-year longitudinal cohort study of 168 parous women. Health, lifestyle and infant feeding questionnaires, blood samples, anthropometry and body composition were collected. Cardiovascular risk was estimated using QRISK®3 and hierarchical multiple linear regression analysis performed.

RESULTS

Mean age was 42.4 years (SD 3.8; range 31-50) and 98.7% (n = 156/158) were premenopausal. Ever breastfeeding rates were 72.6% (n = 122/168) and 37.5% (n = 63/168) lifetime ≥12 months breastfeeding duration. Median durations were 5.5 weeks for exclusive breastfeeding (IQR 35.8; range 0-190) and 30.5 weeks for any breastfeeding (IQR 84.0; range 0-488). Breastfeeding duration was not associated with QRISK®3 scores in adjusted models. Lower glycoprotein acetyls were associated with ever breastfeeding (P = 0.03), and lifetime breastfeeding ≥12 months (P = 0.001). Lifetime breastfeeding ≥12 months and longer exclusive breastfeeding were associated with lower fat mass index (P = 0.03, P = 0.01), tissue percentage fat (P = 0.02, P = 0.009) and visceral adipose tissue volume (P = 0.04, P = 0.025) after correcting for confounders including body mass index.

CONCLUSION

Longer breastfeeding is associated with favorable body composition and lower glycoprotein acetyls, a novel inflammatory biomarker associated with cardiometabolic risk. Breastfeeding is a low-cost, health promoting behavior for women and infants. Pregnant women, especially those at higher risk of cardiovascular disease, should be counseled about the potential benefits of exclusive and longer breastfeeding duration.

Comparison of Breastfeeding Success by Mode of Delivery

OBJECTIVE

This article identifies how mode of delivery and the presence of labor affect the initiation and effectiveness of breastfeeding.

STUDY DESIGN

This is a retrospective cohort study of breastfeeding success after vaginal delivery, cesarean section after labor, and scheduled cesarean section in term, singleton deliveries in nulliparous patients at a large academic institution from 2017 to 2018. Exclusion criteria included major postpartum complications requiring admission to the surgical intensive care unit or neonatal intensive care unit, general anesthesia, and major fetal anomalies. Breastfeeding success in the immediate postpartum period, defined as the first 2 to 3 days postpartum prior to hospital discharge, was measured by the presence of breastfeeding, the need for formula supplementation, the average number of breastfeeding sessions per day, the average amount of time spent at each breastfeeding session, the average number of newborn stools and wet diapers produced daily, and the neonatal percentage in weight loss over the first 2 to 3 days of life. Multivariable linear and logistic regression were used to assess the association between mode of delivery and markers of breastfeeding success after adjusting for potential confounders. A Tukey's post hoc analysis with pairwise comparisons was performed to assess differences in breastfeeding outcomes between vaginal delivery, scheduled cesarean section, and cesarean section after labor.

RESULTS

A total of 2,966 women met inclusion criteria during the study period, 1,936 (65.3%) of whom underwent spontaneous vaginal delivery, 415 (14.0%) of whom delivered by scheduled cesarean section, and 615 (20.7%) of whom underwent cesarean section after labor. There were significant differences in maternal age, obesity, race/ethnicity, insurance status, gestational age at delivery, birth weight, and 1-minute Apgar's score less than 7 between vaginal delivery, scheduled cesarean section, and cesarean section after labor. There were also significant differences between indication for oxytocin, type of anesthesia, and postpartum hemorrhage between the three groups. After controlling for these factors, women who underwent vaginal delivery were more likely to have infants with decreased need for formula supplementation (adjusted odds ratio [aOR] = 1.71, 95% confidence interval [CI]: 1.52-1.93) and were less likely to switch from breast to formula feeding (aOR = 1.71, 95% CI: 1.04-1.31) in comparison to women who delivered via cesarean section in labor or scheduled cesarean section. The infants of these women also had an increased number of breastfeeding sessions on average (β = 0.06, p = 0.002), required fewer number of daily formula feedings (β = 0.14, p < 0.001), and experienced a smaller percentage in neonatal weight loss over the first 2 to 3 days of life (β = 0.18, p < 0.001) compared to those born after cesarean section and cesarean section after labor. These women comparatively required less time at each breastfeeding session (β = 0.06, p = 0.005), and produced fewer wet diapers and stools on average (β = 0.12, p < 0.001 and β = 0.12, p < 0.001, respectively). On post hoc analysis with pairwise comparisons, and on separate sensitivity analysis of only women who underwent cesarean delivery, there was no difference in breastfeeding outcome measures between scheduled cesarean section and cesarean section in labor.

CONCLUSION

Women who deliver by cesarean section, despite the presence or absence of labor, are less likely to maintain exclusive breastfeeding postpartum and are more likely to require formula supplementation. These women may need more support with breastfeeding after surgery in order to experience similar benefits for neonatal growth and weight gain.

KEY POINTS

· Women who deliver by cesarean section are less likely to maintain exclusive breastfeeding.. · Women who deliver by cesarean section are more likely to require formula supplementation.. · Women may need more support with breastfeeding after cesarean delivery..

Effects of a Person's Lactation History on Later-Life Development of Alzheimer's Disease: An Integrative Review

Objective: The purpose of this integrative review is to assess the existing evidence regarding the effects of a person's lactation history on later-life development of Alzheimer's disease. Methods: The authors searched the electronic databases PubMed, Cumulative Index to Nursing and Allied Health Literature, Scopus, and Excerpta Medica dataBASE, and performed backward reference searches using search terms such as, "Alzheimer's disease, dementia," and "breastfeeding, lactation." Authors selected relevant records through the application of inclusion and exclusion criteria and reading the titles, abstracts, or records in full. Results: In total, 400 articles were identified, and 10 articles meeting inclusion criteria were analyzed. Authors extracted data following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and scored levels of evidence according to Melnyk and Fineout-Overholt. Data were organized according to themes of breastfeeding duration, ever having breastfed, and indirect effects of breastfeeding. Conclusions: Breastfeeding may have neuroprotective effects for the lactating person and reduce the risk of later-life development of Alzheimer's disease. However, future research is necessary to determine the generalizability of this association.

Atrial fibrillation considerations in the fourth trimester (postpartum period)

Postpartum atrial fibrillation is an uncommon but increasingly prevalent tachyarrhythmia that merits special management considerations with regards to the safety and efficacy of anticoagulation, rate and rhythm control as well as drug exposure to infants throughout breastfeeding. In this state-of-the-art review, we examine the demographics of postpartum atrial fibrillation with its associated risk factors, describe the safety of commonly used atrial fibrillation therapies, and discuss important considerations for women considering subsequent pregnancies.

Pregnancy, Reproductive Factors, and Female Heart Failure Risk and Outcomes

PURPOSE OF REVIEW

The purpose of this review is to provide an overview of recent evidence on female-specific risk factors related to reproductive status or pregnancy.

RECENT FINDINGS

Pregnancy-related factors, including hypertensive disorders and gestational diabetes, increase the risk of heart failure in women, while breastfeeding and hormone therapy may offer protection. Hypertensive disorders of pregnancy, gestational diabetes, polycystic ovarian syndrome, placental abruption, younger maternal age at first live birth, younger maternal age at last live birth, number of stillbirths, number of pregnancies, onset of menstruation before 12 years of age, shorter reproductive age, ovariectomy, and prolonged absence of ovarian hormones may increase the risk of heart failure in women. Conversely, breastfeeding status and hormone therapy (for menopause or contraception) may serve as protective factors, while fertility treatments have no discernible effect on the risk of heart failure.

Postpartum Hemorrhage after Vaginal Delivery is Associated with a Decrease in Immediate Breastfeeding Success

OBJECTIVE

 This study aimed to identify the impact of postpartum hemorrhage (PPH) after vaginal delivery on immediate breastfeeding success.

STUDY DESIGN

 This is a retrospective cohort study examining the impact of PPH on breastfeeding for nulliparous patients after term, singleton, vaginal deliveries at a large academic institution from 2017 to 2018. Indicators of successful breastfeeding in the immediate postpartum period were measured by the presence of breastfeeding, the need for formula supplementation, the average number of breastfeeding sessions per day, the average amount of time spent at each breastfeeding session, the average number of newborn stools and wet diapers produced daily, and the neonatal percentage in weight loss over the first 2 to 3 days of life.

RESULTS

 A total of 1,904 women met inclusion criteria during the study period, 262 (13.8%) of whom experienced PPH, defined as an estimated blood loss of 500 mL or greater after vaginal delivery. Women who had a PPH had significantly fewer breastfeeding sessions on average (β = -0.06, p-value 0.01) and required more time at each breastfeeding session (β = 0.08, p-value <0.002). Neonates of women with PPH had a larger percentage in weight loss over the first 2 to 3 days of life compared with those without PPH (β = 0.06, p = 0.008).

CONCLUSION

 Women who experience PPH after vaginal delivery have a decreased number of breastfeeding sessions despite spending more time trying to breastfeed, and an increased percentage in neonatal weight loss over the first 2 to 3 days of life. Further work is needed to elicit the mechanism behind this association; however, it is possible that PPH results in decreased secretion of endogenous oxytocin from the hypothalamic-pituitary axis as a result of hypovolemia. These women may therefore require additional breastfeeding support for successful breastfeeding initiation in the immediate postpartum period.

KEY POINTS

· Women who experience PPH after vaginal delivery have decreased breastfeeding success.. · Further work is needed to elicit the mechanism behind this association.. · These women may require additional support for successful breastfeeding initiation postpartum..

The concentration of maternal sacubitril/valsartan transferred into human milk is negligible

Background

Peripartum cardiomyopathy (PPCM) is a common cause of heart failure (HF) in the peripartum. Some medications are considered safe while breastfeeding. However, sacubitril/valsartan (Entresto), while efficacious, is not recommended in breastfeeding women due to concerns about adverse infant development, and no published data suggest otherwise.

Objectives

This study aimed to assess the transfer of sacubitril/valsartan into human milk and evaluate the infant's risk of drug exposure.

Methods

The InfantRisk Human Milk Biorepository released samples and corresponding health information from five breastfeeding maternal-infant dyads exposed to sacubitril/valsartan. Sacubitril, valsartan, and LBQ657 (sacubitril active metabolite) concentrations were determined using liquid chromatography-mass spectrometry (LC/MS/MS) from timed samples 0, 1, 2, 4, 6, 8, 10, and 12 h following medication administration at steady state conditions.

Results

Valsartan levels were below the detection limit of 0.19 ng/mL in all milk samples. Sacubitril was measurable in all milk samples of the five participants, peaking 1 h after drug administration at a mean concentration of 1.52 ng/mL for a total infant dose of 0.00049 mg/kg/12 h and a relative infant dose (RID) calculated at 0.01%. The maximum concentration of its active metabolite LBQ657 in the milk samples was observed 4 h after medication administration and declined over the remaining 12-h dosing interval, for an average concentration of 9.5 ng/mL. The total infant dose was 0.00071 mg/kg/12 h, and the RID was 0.22%. Two mothers reported continuing to breastfeed while taking sacubitril/valsartan; both mothers stated observing no negative effects in their breastfed infants.

Conclusion

The transfer of sacubitril/valsartan into human milk is minimal. These concentrations are unlikely to pose a significant risk to breastfeeding infants, with a combined calculated RID of <0.25%, which is far lower than the industry safety standards (RID <10%).

Awareness of the Maternal Health Benefits of Lactation Among U.S. Pregnant Individuals

INTRODUCTION

We assessed awareness of the maternal health benefits of lactation among a sample of nulliparous pregnant individuals in the United States, identified variables associated with awareness of these benefits, and examined whether awareness of these benefits impacts breastfeeding attitudes or intentions.

METHODS

We administered a web-based survey to nulliparous U.S.-born individuals carrying a singleton gestation of at least 28 weeks. We assessed awareness of the maternal health benefits of lactation using 10 items to create a summative score. We examined variation in awareness of these benefits by demographic characteristics, health insurance, and personal or family health history and used multivariable models to estimate associations between awareness of the maternal health benefits of lactation and breastfeeding intentions.

RESULTS

Of the 675 individuals invited to complete surveys, 451 (67%) responded. Only 50% were aware that breastfeeding lowers maternal risk of breast cancer; fewer were aware that breastfeeding lowers the risk of ovarian cancer (35%), diabetes (27%), and hypertension and heart disease (26%). Awareness of the maternal benefits of lactation did not vary by age or race/ethnicity. However, significant regional variation was noted. In multivariable models, scores of awareness of the maternal health benefits of breastfeeding were significantly associated with intentions to breastfeed for at least 12 months (adjusted odds ratio, 1.23; 95% confidence interval, 1.11, 1.37).

CONCLUSIONS

Efforts to increase awareness of the maternal health benefits of lactation are still needed. Increasing awareness of the maternal health benefits of lactation may strengthen intentions to breastfeed as recommended.

Association of Handgrip Strength and Cardiovascular Disease Risk Among Middle-Aged Postmenopausal Women: An Analysis of the Korea National Health and Nutrition Examination Survey 2014-2019

Purpose

Handgrip strength is an indicator of overall muscle strength and has been associated with an increased risk of cardiovascular disease. Evidence suggests that menopause is a risk factor for cardiovascular disease in women, and muscle strength decreases progressively after menopause. Despite the prognostic importance of the decline in muscle strength and increased cardiovascular disease risk among postmenopausal women, evidence of their association is limited. This study aimed to investigate the relationship between handgrip strength and cardiovascular disease risk among postmenopausal, middle-aged Korean women.

Patients and Methods

Using pooled cohort equations, we calculated the 10-year risk of atherosclerotic cardiovascular disease (ASCVD) among postmenopausal women (N = 2019) aged 50-64 years without cardiovascular disease history from the 2014-2019 Korea National Health and Nutrition Examination Survey. Relative grip strength was defined as measured grip strength divided by body mass index. Logistic regression analysis of a complex sampling design was performed to evaluate the association between relative grip strength and a predicted 10-year ASCVD risk ≥7.5%.

Results

The average handgrip strength was 24.8 kg, and 5.2% of women were considered for sarcopenia (<18 kg). The quartile-stratified relative grip strength was negatively associated with 10-year ASCVD risk (p < 0.001). In the multiple logistic regression analysis, the adjusted odds ratio for the highest relative grip strength quartile was 0.53 (95% confidence interval [CI]: 0.36-0.78), and that of the group who breastfed for more than 12 months was 1.75 (95% CI: 1.36-2.25) for 10-year ASCVD risk.

Conclusion

Increased handgrip strength may be associated with lower cardiovascular disease risk among middle-aged postmenopausal women in Korea. Our findings provide critical evidence regarding the importance of increasing handgrip strength among postmenopausal, middle-aged women to reduce cardiovascular disease risk. Handgrip strength measurement might be a valuable screening tool for cardiovascular disease prevention.

Relationship Between Psychological Empowerment and Nurses' Job Satisfaction: A Systematic Review and Correlational Meta-Analysis

Psychological empowerment is a motivational concept that encompasses a person's thoughts and perceptions that give a sense of behavior and commitment to the work. Psychological empowerment is widely acknowledged to be associated with nurses' job satisfaction. However, this relationship has been found to be controversial. Therefore, this systematic review and meta-analysis aimed to investigate the relationship between psychological empowerment and nurses' job satisfaction. The electronic databases CINAHL, PubMed, Web of Science, and Google Scholar were utilized to search for relevant studies published from 2001 to 2024. The correlation coefficients were extracted for each eligible study and transformed into Fisher's Z. Then, the pooled effect size (r coefficient) was computed using Fisher's Z and the corresponding standard error. Moreover, I2 was used to assess the heterogeneity of studies. Begg's rank and Egger's test were employed to assess the publication bias. Sensitivity analysis was utilized to measure the robustness of study findings using the one-leave-out approach, and a critical appraisal tool for cross-sectional studies was adopted to assess the quality of included studies. A total of 18 studies were selected for analysis with a total sample of 6,353 nurses from different countries. The included studies ranged from moderate to high quality based on the quality assessment checklist. The pooled effect size for the correlation between psychological empowerment and nurses' job satisfaction was 0.512 (95% confidence interval = 0.406-0.604) with mild-to-moderate heterogeneity. Moreover, the majority of the studies confirmed a positive relationship between the two measured concepts. This study presents evidence indicating that psychological empowerment has a sensible relationship with nurses' job satisfaction. Therefore, nurse administrators should implement tailored strategies to trigger nurses' psychological empowerment, aiming to boost job satisfaction and reduce turnover and burnout. However, additional studies are essential to establish a causal relationship.

A cross-sectional study of the association between breastfeeding history and overweight/obesity in postmenopausal women

OBJECTIVES

This study endeavors to augment comprehension of the association between breastfeeding and maternal weight within Asian populations.

METHODS

Data were obtained from the comprehensive 2011 research titled "Risk Evaluation of Cancers in Chinese Diabetic Individuals (REACTION): a longitudinal analysis," focusing specifically on postmenopausal women residing in the metropolitan precincts of Guiyang. It presents a cross-sectional study involving 5,987 parous postmenopausal women, aged 60.1 ± 6.9 years, who underwent assessments of body mass index and waist-to-height ratio. The probability of excessive weight or obesity was evaluated in relation to the aggregate duration of breastfeeding, using single-factor and multivariate logistic regression analyses.

RESULTS

Following multiple adjustments for different confounders, the odds ratios (ORs) demonstrated that women who had borne a single child and breastfed for more than 12 months exhibited an increased prevalence of excessive weight (body mass index ≥24 kg/m 2 ) in contrast to those who abstained from breastfeeding (model I: OR, 1.481; 95% confidence interval, 1.124-1.952; P = 0.005; model II: OR, 1.471; 95% confidence interval, 1.113-1.944; P = 0.007). Conversely, among the subset of women who had given birth to two or more children, no noteworthy associations emerged between breastfeeding duration and the propensity for excessive weight or obesity (all models).

CONCLUSION

In the Asian population, the duration of breastfeeding does not appear to be necessarily linked to the prevalence of overweight or obesity in postmenopausal women.

Breastfeeding Practices in Patients with Heart Disease Stratified by Area Deprivation Index

Objective: We sought to evaluate breastfeeding (BF) practices in patients with maternal cardiac disease (MCD) stratified by area deprivation index (ADI) to identity communities at risk. Study Design: Retrospective cohort of patients managed by the University of Alabama at Birmingham (UAB) Cardio-Obstetrics Program. Patients were included if they had ≥1 prenatal visit with the Cardio-Obstetrics team, delivered at UAB, and had a street address on file. The primary outcome was BF rate at hospital discharge. Secondary outcomes included BF intent on admission and BF at the postpartum (PP) visit. ADI reports socioeconomic disadvantage at the census tract level; 1 = least deprived and 100 = most deprived. Baseline characteristics and BF rates were compared by ADI categories: Low (ADI 1-33), medium (ADI 34-66), and high (ADI 67-100). Results: One hundred and forty-eight patients were included: 14 (10%) low, 42 (28%) medium, and 92 (62%) high ADI. Patients in the high ADI category were younger relative to those in the medium or low ADI (26 versus 28 versus 32 years; p < 0.01) and less likely to be married or living with a partner (30.4% versus 58.5% versus 71.4%; p < 0.01), There was no difference in BF intent between the lowest, medium, and highest ADI categories (85.7% versus 85.4% versus 81.6%; p = 0.38) or BF rates at hospital discharge (100% versus 92.7% versus 85.6%, p = 0.23). However, there was a significant difference in BF rates at the PP visit (90% versus 63.0% versus 38.6%; p < 0.01) even after controlling for differences in baseline characteristics (odds ratio = 0.11 (95% confidence interval [0.01-0.93]), p = 0.043). Conclusions: There was an association between living in a resource-poor community and early cessation of BF in our population of patients with MCD. Community-based interventions targeting mothers with heart disease living in high ADI communities may help these individuals achieve higher BF rates.

Discordance in exclusive breastfeeding between maternal recall and deuterium dose-to-mother technique during the first 6 months of infants: A multi-country study in Asia

PURPOSE

This study aimed to assess the agreement in EBF between maternal recall and the dose-to-mother (DTM) technique.

METHODS

Indonesia, Malaysia, Mongolia, Pakistan, Sri Lanka, Thailand, and Vietnam participated in the study. A total of 207 and 118 mother-infant pairs were assessed at 3 and 6 months of child's age. Using a standardized questionnaire, mothers were asked to recall child feeding during the previous 24 h, at 3 and 6 months. Those recalled to be EBF proceeded to be assessed using DTM technique. Non-milk oral intake (NMOI) cutoff of 86.6 g/d was used to classify EBF.

RESULTS

According to DTM, 66% of infants were EBF at 3 months, while only 22% were EBF at 6 months. At 3 months, the overall % agreement between maternal recall and DTM method was 68%, kappa 0.06 (95% CI: 0.07-0.20), and at 6 months, the % agreement was only 21%, kappa -0.031 (95% CI -0.168 to 0.107). Human milk intakes were similar at 3 months and 6 months when expressed as g/d, but decreased when expressed as g/kg/d, with a large variation within and between countries; Pakistan being the lowest.

CONCLUSION

This study showed there were declining levels of EBF from 3 to 6 months in the participating countries from Asia and the agreement between maternal recall and DTM technique to classify EBF was low. To ensure that the DTM technique can be more widely used in evaluating breastfeeding promotion programs, consensus on the appropriate NMOI cutoff and simplification of the DTM protocol is necessary.

An Educational Intervention to Explore and Overcome Nursing Students' Breastfeeding Barriers: A Mixed-Methods Quasi-experimental Study

BACKGROUND

Nursing and midwifery students do not feel adequately prepared during their clinical training to support women who breastfeed, demanding more effective communication skills and knowledge.

AIM

The aim was to evaluate changes in students' breastfeeding knowledge.

METHODS

This was a mixed-methods quasi-experimental design. Forty students voluntarily participated. Using a 1:1 ratio, 2 groups were randomly created and completed the validated questionnaire ECoLaE (pre-post). The educational program consisted of focus groups, a clinical simulation, and a visit to the local breastfeeding association.

FINDINGS

The control group's posttest scores ranged from 6 to 20 (mean = 13.1, standard deviation [SD] = 3.0). The intervention group ranged from 12 to 20 (mean = 17.3, SD = 2.3). A Student's t test for independence samples was calculated ( P < .005, t = 4.5, median = 4.2). The intervention group had a mean difference of 10 points in improvement (mean =10.53, SD = 2.20, min = 7, max = 14), whereas the control group had a mean of 6 points (mean = 6.80, SD = 3.03, min = 3, max = 13). The multiple linear regression explained the intervention's effect. The regression model had statistical significance ( F = 4.87, P = 0.004), with an adjusted R2 = 0.31. The linear regression between the posttest scores and group variables after adjusting by age showed an increment of 4.1 points in the intervention posttest scores ( P < .005, 95% confidence interval [CI] = 2.1-6.1).

CONCLUSIONS

The educational program "Engage in breaking the barriers to breastfeeding" improved nursing students' knowledge.

Prenatal Counseling on the Maternal Health Benefits of Lactation: A Randomized Trial

Objective: To assess the effects of prenatal counseling about the maternal health benefits of lactation on postpartum knowledge, breastfeeding intentions, and infant feeding behaviors. Materials and Methods: We conducted a randomized trial with 411 nulliparous U.S.-born women carrying a singleton gestation. Participants were recruited online; after completing a baseline survey that assessed breastfeeding knowledge and intentions, participants were randomized to receive a 10-minute virtual counseling session about the benefits of breastfeeding or attention-control counseling about smoke-free homes. We collected data on breastfeeding knowledge, intentions, and infant feeding behaviors through 12 months postpartum and conducted an intention-to-treat analysis. Results: On enrollment, awareness of the maternal health benefits of lactation was similarly low in both study groups. Postpartum, participants who received this prenatal counseling intervention had significantly greater awareness that breastfeeding decreases maternal risk of breast cancer, ovarian cancer, diabetes, heart disease, and rheumatoid arthritis (p < 0.001 for all). On enrollment, intended duration of breastfeeding was similar between groups (10.1 months versus 9.7 months, p = 0.41). At 1-month postpartum, intended duration of breastfeeding had increased from baseline among those who received this counseling (+0.7 months versus -0.7 months among controls, p = 0.004); among intervention participants intended duration of breastfeeding decreased less at 3 (-0.8 versus -1.6, p = 0.18), 6 (-2.0 versus -3.0, p = 0.06), 9 (-2.8 versus -4.2, p = 0.03), and 12 months postpartum (-4.8 versus -6.2, p = 0.09). Rates of exclusive breastfeeding and any breastfeeding were similar between groups. Conclusion: Prenatal counseling on the maternal health benefits of lactation increases awareness of these maternal health benefits and extends intended duration of breastfeeding. ClinicalTrials.gov Identifier: NCT04601987.

Translation and validation of the Chinese version of the comprehensive breastfeeding knowledge scale (CBKS)

BACKGROUND

The level of breastfeeding knowledge of nursing students may influence their ability to support breastfeeding families. However, to date, it has not been possible to measure this accurately due to the lack of existence of a validated tool in Chinese.

OBJECTIVES

To translate the Comprehensive Breastfeeding Knowledge Scale (CBKS) into Chinese, and then evaluate its psychometric properties among Chinese undergraduate nursing students in order to inform and evaluate a nursing breastfeeding education programme.

METHODS

The Brislin translation model was followed, and a three-phase process (translation, back-translation and cultural adaptation) was used to sinicize the CBKS and evaluate its content validity. Construct validity was evaluated with exploratory factor analysis (EFA), and the reliability of internal consistency of the Chinese version of the CBKS was tested by calculating Cronbach's alpha coefficient and the half reliability coefficient.

SETTINGS

Two nursing schools in Beijing and Nanjing, China.

PARTICIPANTS

Four hundred and thirty-nine undergraduate nursing students (257 from Beijing and 182 from Nanjing).

RESULTS

Five experts rated the content validity of the Chinese version of the CBKS as excellent. EFA showed that the Chinese version of the CBKS had three subscales and 23 items. Cronbach's alpha coefficient of the Chinese version of the CBKS and the half reliability coefficient were 0.70 and 0.73, respectively. Students who had completed an obstetrics or paediatric nursing course had significantly higher total scores and mean scores for most items compared with those who had not taken a course. Most of the indictors of EFA met the standards of construct validity, and some were very close to the cut-off.

CONCLUSION

Overall, the 23-item Chinese version of the CBKS is an acceptable tool to measure the level of breastfeeding knowledge among undergraduate nursing students. This scale can be used to inform the design and evaluation of breastfeeding education materials for nursing students or other health profession students.

Breastfeeding Associated with Lower Prevalence of Metabolic Syndrome in Women with Gestational Diabetes in the Very Early Postpartum Period

OBJECTIVE

The aim of this study is to examine the association of breastfeeding with metabolic syndrome (MetS) in women with recent gestational diabetes mellitus (GDM) in the very early postpartum (PP) period.

STUDY DESIGN

We performed a secondary analysis of the Balance After Baby Intervention (BABI) study which enrolled women with recent GDM. Data collected during an early (~8 weeks) PP visit were used in this analysis. At this visit, weight, height, waist circumference (WC), blood pressure (BP), fasting plasma glucose (FPG), and lipids were obtained. MetS was classified per National Cholesterol Education Program Adult Treatment Program III (NCEP-ATP III) criteria. We defined breastfeeding as currently breastfeeding or not currently breastfeeding for the main analysis.

RESULTS

Of 181 women enrolled in BABI, 178 were included in this analysis (3 excluded for missing lipids). Thirty-four percent were Hispanic. Of non-Hispanics, 31.5% were White, 18.5% Asian, and 12.9% Black/African American. The prevalence of MetS was 42.9% in women not breastfeeding versus 17.1% in women breastfeeding (p < 0.001; adjusted odds ratio [aOR] = 0.16 [95% confidence interval (CI): 0.06-0.41]). Breastfeeding women had significantly lower odds of FPG ≥100 mg/dL (aOR = 0.36 [95% CI: 0.14-0.95], p = 0.039), HDL < 50 mg/dL (aOR = 0.19 [95% CI: 0.08-0.46], p < 0.001), and triglycerides (TG) ≥ 150 mg/dL (aOR = 0.26 [95% CI: 0.10-0.66], p = 0.005). When evaluated as continuous variables, WC, FPG, and TG were significantly lower and HDL significantly higher in women breastfeeding in the very early PP period (vs. not breastfeeding).

CONCLUSION

In a diverse population of women with recent GDM, there was lower prevalence of MetS in women breastfeeding compared with those not breastfeeding in the very early PP period. This study extends the findings of an association of breastfeeding with MetS previously reported at time points more remote from pregnancy to the very early PP period and to an ethnically and racially diverse population.

KEY POINTS

· MetS prevalence in women with recent GDM was lower in breastfeeding than not breastfeeding women.. · FPG, HDL, WC, and TG were improved in the breastfeeding group.. · This study extends prior findings to the very early PP period and to a diverse population..

Association between parities and duration of breastfeeding and the severity of coronary artery disease in women above 30 years old age (A pilot study)

Background

The prevalence and mortality of CVD in women increase over time. We conducted this research to evaluate the severity of coronary artery disease with the number of live births and breastfeeding duration.

Methods

Patients aged 30-50 years old with positive exercise tests or evidence of cardiac ischemia who were candidates for coronary angiography were included. All the participants had at least one child. Syntax score was used to evaluate the severity of coronary arteries.

Results

Mean number of children was 3.72±1.85, in those patients with <2 live births no one had a syntax score≥1, but in the>5 live births group most patients had a syntax score≥1. In patients with zero syntax score, it was estimated as 4.91±39.7; in patients with 1≤ syntax score, it was 4.48±7.29 (P =0.76). Among patients with > 5 birth lives, those with higher syntax scores had older ages (P=0.497). After adjusting age, the association between live births and syntax score became non-significant (P=0.850).

Conclusion

By increasing the number of live births >5, the severity of coronary artery disease, increases. However, this association was not significant after adjusting the age of patients.

Reproductive risk factors for cardiovascular disease in women

Cardiovascular disease (CVD) remains the leading cause of death for women. Adverse pregnancy outcomes, including hypertensive disorders of pregnancy, gestational diabetes mellitus, preterm delivery, and low birth weight-affecting up to 30% of pregnant women-increase the risk of CVD. Early menarche and polycystic ovary syndrome are implicated. Premature and early menopause and significant vasomotor symptoms are all associated. Including reproductive risk assessment is critical when determining CVD risk and implementing evidence-based prevention strategies.

Breastfeeding-Related Health Benefits in Children and Mothers: Vital Organs Perspective

Breast milk (BM) is a constantly changing fluid that represents the primary source of nutrition for newborns. It is widely recognized that breastfeeding provides benefits for both the child and the mother, including a lower risk of ovarian and breast cancer, type 2 diabetes mellitus, decreased blood pressure, and more. In infants, breastfeeding has been correlated with a lower risk of infectious diseases, obesity, lower blood pressure, and decreased incidence of respiratory infections, diabetes, and asthma. Various factors, such as the baby's sex, the health status of the mother and child, the mother's diet, and the mode of delivery, can affect the composition of breast milk. This review focuses on the biological impact of the nutrients in BM on the development and functionality of vital organs to promote the benefit of health.

Deficiencies in the Intentions, Attitudes, and Knowledge of Future Healthcare Professionals Regarding Breastfeeding

The aim of this study was to determine the level of knowledge, positive intentions, and attitudes regarding breastfeeding among university students. A validated questionnaire collected data from 236 students of the Faculty of Dental Medicine and Health Osijek about breastfeeding intentions, attitudes, and knowledge. Descriptive methods were used to present the students' results in terms of their intentions, attitudes, and knowledge. For each question included in the questionnaire, the maximum possible and maximum achieved numbers of points were calculated, as well as the percentage of points achieved in relation to the maximum possible number. Correlations between the results on individual scales of the questionnaire and the total results of the questionnaire are shown by Spearman's correlation coefficient. Questionnaire answers that were least in line with professional recommendations were selected and analyzed. We found that the areas that should be given special attention in the education of students are: the intention of breastfeeding for more than a year; the use of breaks for breastfeeding in the workplace; attitudes and knowledge about the quality of breast milk in relation to substitutes; attitudes about breastfeeding in public places and breastfeeding for more than two years; and the feeling of maternity and breastfeeding (compared to bottle feeding). The relationship between the results was considered in terms of intentions, attitudes, and knowledge in relation to the overall results of the questionnaire, and the authors' thoughts on the reasons behind the poorer results achieved for certain questions were presented.

Factors Affecting BMI Changes in Mothers during the First Year Postpartum

We tested the hypotheses that mothers of infants who exclusively breastfed would differ in the trajectories of postpartum BMI changes than mothers of infants who exclusively formula fed, but such benefits would differ based on the maternal BMI status prepregnancy (primary hypothesis) and that psychological eating behavior traits would have independent effects on postpartum BMI changes (secondary hypothesis). To these aims, linear mixed-effects models analyzed measured anthropometric data collected monthly from 0.5 month (baseline) to 1 year postpartum from two groups of mothers distinct in infant feeding modality (Lactating vs. Non-lactating). While infant feeding modality group and prepregnancy BMI status had independent effects on postpartum BMI changes, the benefits of lactation on BMI changes differed based on prepregnancy BMI. When compared to lactating women, initial rates of BMI loss were significantly slower in the non-lactating women who were with Prepregnancy Healthy Weight (β = 0.63 percent BMI change, 95% CI: 0.19, 1.06) and with Prepregnancy Overweight (β = 2.10 percent BMI change, 95% CI: 1.16, 3.03); the difference was only a trend for those in the Prepregnancy Obesity group (β = 0.60 percent BMI change, 95% CI: −0.03, 1.23). For those with Prepregnancy Overweight, a greater percentage of non-lactating mothers (47%) gained ≥ 3 BMI units by 1 year postpartum than did lactating mothers (9%; p < 0.04). Psychological eating behavior traits of higher dietary restraint, higher disinhibition, and lower susceptibility to hunger were associated with greater BMI loss. In conclusion, while there are myriad advantages to lactation, including greater initial rates of postpartum weight loss regardless of prepregnancy BMI, mothers who were with overweight prior to the pregnancy experienced substantially greater loss if they breastfed their infants. Individual differences in psychological eating behavior traits hold promise as modifiable targets for postpartum weight management.

Breastfeeding and Later-Life Cardiometabolic Health in Women With and Without Hypertensive Disorders of Pregnancy

Background Breastfeeding is associated with improved cardiometabolic profiles decades after pregnancy. Whether this association exists for women who experience hypertensive disorders of pregnancy (HDP) is unknown. The authors examined whether breastfeeding duration or exclusivity are associated with long-term cardiometabolic health, and whether this relationship differs by HDP status. Methods and Results Participants (N=3598) were from the UK ALSPAC (Avon Longitudinal Study of Parents and Children) cohort. HDP status was assessed by medical record review. Breastfeeding behaviors were assessed by contemporaneous questionnaires. Breastfeeding duration was categorized as never, <1, 1 to <3, 3 to <6, 6 to <9, and 9+ months. Breastfeeding exclusivity was categorized as never, <1, 1 to <3, and 3 to 6 months. Measures of cardiometabolic health (body mass index, waist circumference, C-reactive protein, insulin, proinsulin, glucose, lipids, blood pressure, mean arterial pressure, carotid intima-media thickness, and arterial distensibility) were measured 18 years after pregnancy. Analyses were conducted using linear regression adjusting for relevant covariates. Breastfeeding was associated with improved cardiometabolic health (lower body mass index, waist circumference, C-reactive protein, triglycerides, insulin, and proinsulin) in all women, but not for every breastfeeding duration. Interaction tests revealed additional benefits in women with a history of HDP, with the strongest benefit observed in the 6- to 9-month breastfeeding category (diastolic blood pressure, -4.87 mm Hg [95% CI, -7.86 to -1.88], mean arterial pressure -4.61 [95% CI, -7.45 to -1.77], and low-density lipoprotein cholesterol, -0.40 mmol/L [95% CI, -0.62 to -0.17 mmol/L]). Differences in C-reactive protein and low-density lipoprotein "survived" Bonferroni correction (P<0.001). Similar results were observed in the exclusive breastfeeding analyses. Conclusions Breastfeeding may be a mechanism to reduce the cardiovascular disease sequela associated with HDP; however, there is a need to establish whether associations reflect a causal effect.

Negative effects of long parental leave on maternal health: Evidence from a substantial policy change in Austria

I study the effect of parental leave duration on maternal health in the short- to medium-run leveraging variation in parental leave duration induced by an Austrian policy reform in the year 2000. Using rich administrative data and a regression discontinuity framework, I find that long parental leave of 2.5 years instead of 1.5 years deteriorates maternal health. Worse mental health mainly drives this effect. Alternative channels such as differential fertility, long-term employment effects, a change in disposable income or alternative mode of childcare are unlikely to be of main importance. There is substantial heterogeneity with longer leave spells being less harmful for mothers with unhealthy babies proxied by low birth weight.

Association of reproductive factors with cardiovascular disease risk in pre-menopausal women: nationwide population-based cohort study

BACKGROUND

Although the morbidity and mortality of cardiovascular diseases (CVD) are rising in young women, the risk factors of CVD among Korean pre-menopausal women have not been intensively investigated.

AIMS

To determine how age at menarche and other female reproductive factors are associated with the risk of CVD in pre-menopausal women.

METHODS AND RESULTS

A total of 1 088 992 pre-menopausal women who participated in health screening in 2009 were included. The study outcomes were myocardial infarction (MI) and ischaemic stroke. Cox proportional hazards regression analysis was conducted with adjustment of traditional CVD risk factors and reproductive factors.

RESULTS

Mean age was 43.8 ± 5.3 years (98.9%, < 55 years), 3.5% were current smokers, and 1.2% were heavy drinkers. During a mean follow-up of 8.3years [9 032 685.9 person-years (PY)], there were 10 876 CVD events (1.0 per 1000 PY).With later menarche, the risk of CVD increased; ≤12 years [adjusted hazard ratio (HR) 1.04, 95% confidence interval 0.93-1.16], 13 years (reference), 14 years (1.06, 0.98-1.14), 15 years (1.15, 1.07-1.24), 16 years (1.23, 1.14-1.34), and ≥17 years (1.33, 1.24-1.44). Compared with non-users, oral contraceptives (OC) users (≥1 year) had an increased risk of CVD (1.11, 1.01-1.22) (P for trend = 0.007).

CONCLUSIONS

Later menarche than the mean age at menarche (13 years old) and the use of OC (≥1 year) were associated with a higher risk of CVD, after adjusting for traditional cardiovascular risk factors. This study suggests that female reproductive factors could be unique risk factors for CVD in pre-menopausal women.

Comparing the effects of breastfeeding in the laid-back and cradle position upon the experiences of primiparous women: a parallel randomized clinical trial

BACKGROUND AND AIM

Appropriate positioning is crucial to successful breastfeeding and its continuation. Positioning can create, prevent, or correct breastfeeding problems. This study aimed to determine and compare the effects of both the laid-back and cradle positions upon the breastfeeding experiences of primiparous (cisgender) women.

METHODS

A parallel randomized clinical trial was conducted with a sample of primiparous women (n = 168) with a gestational age of between 31 and 34 weeks, referring to the perinatal clinic of Shahid Gharazi Hospital in Malayer (Hamadan Province, Iran). Participants were recruited via convenience sampling and allocated to one of two groups: intervention (laid-back position) (n = 85) and control (cradle position) (n = 83) using the random block method. Breastfeeding education was given to both groups during two sessions (weeks 31-34 and 35--37 of pregnancy) by "baby-friendly" accredited hospitals in Iran. The intervention group was instructed on how to breastfeed using the laid-back position. The control group was instructed on how to breastfeed using the cradle position. In the immediate postnatal period, breastfeeding positions were assessed in both groups. Breastfeeding experiences were measured once at the time of participants returning home and again at both 1 week and 2 weeks following birth, using the breastfeeding experience scale. Data analysis was undertaken using the SPSS software version 21. A value of P < 0.05 was considered significant.

RESULTS

No statistically significant difference was observed between the two groups in terms of concerns relating to participants nor their breasts, milk insufficiency, neonate, process, or breastfeeding experience at any time point measured. The means (SDs) of breastfeeding experience at the time of discharge, 1 week, and 2 weeks after childbirth in intervention group were 26.07 (4.533), 26.85 (3.812), and 26.65 (4.632) respectively. The means (SDs) of breastfeeding experience at the time of discharge, 1 week, and 2 weeks after childbirth in control group were 25.42 (3.315), 26.68 (3.872), and 25.41 (4.05) respectively.

CONCLUSION

There is no difference in breastfeeding experiences whether the laid-back or cradle position is used. Thus, broader education on breastfeeding and the provision of comprehensive support may be more effective in optimizing one's experience of breastfeeding.

Peripartum Cardiomyopathy: Risks Diagnosis and Management

Peripartum cardiomyopathy is a rare cause of heart failure that occurs during late pregnancy or in the early postpartum period. Delays in diagnosis may occur as symptoms of heart failure mimic those of normal pregnancy. The diagnosis should be considered in any pregnant or postpartum woman with symptoms concerning for heart failure. If there are clinical concerns, labs including N-terminal pro-BNP should be checked, and an echocardiogram should be ordered to assess for systolic dysfunction. Prompt medical treatment tailored for pregnancy and lactation is essential to prevent adverse events. Outcomes are variable, including complete recovery, persistent myocardial dysfunction with heart failure symptoms, arrhythmias, thromboembolic events, and/or rapid deterioration requiring mechanical circulatory support and cardiac transplantation. It is essential that care is provided as part of a multidisciplinary cardio-obstetrics team including obstetrics, cardiology, maternal fetal medicine, anesthesiology, and nursing. All women with peripartum cardiomyopathy should have close follow-up with a cardiologist, although optimal duration of medical therapy following complete recovery is unknown. Women considering a subsequent pregnancy require preconception counseling and close collaboration between obstetrics and cardiology throughout pregnancy.

Breastfeeding following bariatric surgery among obese women with and without diabetes mellitus

BACKGROUND

Information on exclusive breastfeeding (BF) and BF initiation following bariatric surgery (BS) among obese women with diabetes mellitus (DM) and without DM (non-DM) is limited.

METHODS

Retrospective cohort study. Obesity was defined by BMI (kg/m2) as grade 1 (30-34.9), grade 2 (35-39.9) or grade 3 (≥40). The 65 women in the DM group (40 women with gestational, 19 with Type 2 and 6 with Type 1) was similar to 84 with non-DM in BS type: Roux-en-Y (51 vs 55%), sleeve gastrectomy (32 vs 35%), laparoscopic gastric banding (17 vs 7%) and gastro-duodenal anastomosis (0 vs 4%).

RESULTS

Women with DM were older (35 vs 33y), of advanced age (54 vs 27%), with higher prevalence of grade 3 obesity (66 vs 46%), chronic hypertension (31 vs 10%), delivery of late-preterm infants (23 vs 10%) and neonatal hypoglycemia (25 vs 12%). Although infant feeding intention was similar: BF (66 vs 79%), partial BF (9 vs 7%) or formula (25 vs 14%), at discharge women with DM had lower exclusive BF (29 vs 41%) and BF initiation rates (68 vs 76%) than those with non-DM. Women with grade 3 obesity (52% were DM) differed from those with grades 1-2 (34% were DM) in exclusive BF (27 vs 52%), and BF initiation rates (66 vs 86%).

CONCLUSION

After BS, women with DM, especially those with grade 3 obesity, had higher rates of chronic hypertension and preeclampsia and lower rates of exclusive BF and BF initiation than those who had DM but had less severe obesity.

Pregnancy-related factors may signal additional protection or risk of future cardiovascular diseases

BACKGROUND

Cardiovascular disease (CVD) guidelines recommend using the Pooled Cohort Equation (PCE) to assess 10-year CVD risk based on traditional risk factors. Pregnancy-related factors have been associated with future CVD. We examined the contribution of two pregnancy-related factors, (1) history of a low birthweight (LBW) infant and (2) breastfeeding to CVD risk accounting for traditional risk factors as assessed by the PCE.

METHODS

A nationally representative sample of women, ages 40-79, with a history of pregnancy, but no prior CVD, was identified using NHANES 1999-2006. Outcomes included (1) CVD death and (2) CVD death plus CVD surrogates. We used Cox proportional hazards models to adjust for PCE risk score.

RESULTS

Among 3,758 women, 479 had a LBW infant and 1,926 reported breastfeeding. Mean follow-up time was 12.1 years. Survival models showed a consistent reduction in CVD outcomes among women with a history of breastfeeding. In cause-specific survival models, breastfeeding was associated with a 24% reduction in risk of CVD deaths (HR 0.76; 95% CI 0.45─1.27, p = 0.30) and a 33% reduction in risk of CVD deaths + surrogate CVD, though not statistically significant. (HR 0.77; 95% CI 0.52─1.14, p = 0.19). Survival models yielded inconclusive results for LBW with wide confidence intervals (CVD death: HR 0.98; 95% CI 0.47─2.05; p = 0.96 and CVD death + surrogate CVD: HR 1.29; 95% CI 0.74─2.25; p = 0.38).

CONCLUSION

Pregnancy-related factors may provide important, relevant information about CVD risk beyond traditional risk factors. While further research with more robust datasets is needed, it may be helpful for clinicians to counsel women about the potential impact of pregnancy-related factors, particularly the positive impact of breastfeeding, on cardiovascular health.

Barriers and enablers of breastfeeding in mother-newborn dyads in institutional settings during the COVID-19 pandemic: A qualitative study across seven government hospitals of Delhi, India

Introduction

The COVID-19 pandemic disrupted newborn care and breastfeeding practices across most healthcare facilities. We undertook this study to explore the barriers and enablers for newborn care and breastfeeding practices in hospitals in Delhi, India for recently delivered mother (RDM)-newborn dyads during the first wave of the COVID-19 pandemic (2020) and inductively design a "pathway of impaction" for informing mitigatory initiatives during the current and future pandemics, at least in the initial months.

Materials and methods

We used an exploratory descriptive design (qualitative research method) and collected information from seven leading public health facilities in Delhi, India. We conducted separate interviews with the head and senior faculty from the Departments of Pediatrics/Neonatology (n = 12) and Obstetrics (n = 7), resident doctors (n = 14), nurses (labor room/maternity ward; n = 13), and RDMs (n = 45) across three profiles: (a) COVID-19-negative RDM with healthy newborn (n = 18), (b) COVID-19-positive RDM with healthy newborn (n = 19), and (c) COVID-19 positive RDM with sick newborn needing intensive care (n = 8) along with their care-giving family members (n = 39). We analyzed the data using grounded theory as the method and phenomenology as the philosophy of our research.

Results

Anxiety among clients and providers, evolving evidence and advisories, separation of the COVID-positive RDM from her newborn at birth, providers' tendency to minimize contact duration and frequency with COVID-positive mothers, compromised counseling on breastfeeding, logistic difficulties in expression and transportation of COVID-positive mother's milk to her baby in the nursery, COVID restrictions, staff shortage and unavailable family support in wards and nursery, and inadequate infrastructure were identified as major barriers. Keeping the RDM-newborn together, harmonization of standard operating procedures between professional associations and within and between departments, strategic mobilization of resources, optimization of human resources, strengthening client-provider interaction, risk triaging, leveraging technology, and leadership-in-crisis-situations were notable enablers.

Conclusion

The separation of the RDM and newborn led to a cascade of disruptions to newborn care and breastfeeding practices in the study institutions. Separating the newborn from the mother should be avoided during public health emergencies unless there is robust evidence favoring the same; routine institutional practices should be family centered.

Impact of excessive gestational weight gain on exclusive breastfeeding among women with Type 1 and Type 2 diabetes and obesity

BACKGROUND

Pregestational diabetes, obesity and gestational weight gain (GWG) are associated with adverse perinatal outcomes, however, the influence of excessive GWG on lactation at discharge is less known. Our aim is to evaluate the impact of excessive GWG using the LifeCycle project guidelines on exclusive breastfeeding (EBF) and any BF rates at discharge among 171 women with Type 1 and 294 Type 2 diabetes and obesity who intended to BF.

METHODS AND FINDINGS

Retrospective cohort study. Obesity was defined by BMI (kg/m2) as grade 1 (30-34.9), grade 2 (35-39.9) or grade 3 (≥40). GWG was categorized as adequate, inadequate or excessive according to the 2019 LifeCycle Project guidelines. Women with Type 1 were younger (30 vs 33y), primiparous (51 vs 32%), delivered earlier (37 vs 38w) than women with Type 2 andwere different in grade 1 (40 vs 26%), grade 3 obesity (19 vs 49%) and median GWG (15 vs 11kg). Of all 465 women with Type 1 and Type 2 combined, 365 (78%) who had excessive GWG and 100 (22%) who had non-excessive GWG showed similar EBF (27 vs 25%) and any BF (72 vs 72%) rates. Regression analysis showed that after adjusting for potential confounders excessive GWG was not a predictor of EBF or any BF at discharge.

CONCLUSION

Type 1 and Type 2 diabetes, obesity and excessive GWG are associated with low EBF, however, excessive GWG is not an independent predictor of low EBF or any BF at discharge.

Work as an Understudied Driver of Racial Inequities in Breastfeeding

Breastfeeding inequities by race are a persistent public health problem in the United States. Inequities in occupation and working conditions likely contribute to relatively less breastfeeding among Black compared to White mothers, yet little research has addressed these interrelationships. Here, we offer a critical review of the literature and a conceptual framework to guide future research about work and racial inequities in breastfeeding. There is a strong public health case for promoting breastfeeding equity for mothers across race groups and occupation types. Existing theory suggests that employment opportunities and working conditions are a likely pathway that connects structural racism to Black-White breastfeeding inequities, in addition to other known factors. We propose a new conceptual model for studying the interrelationships among work, race, and breastfeeding outcomes.

The Fourth Trimester: a Time for Enhancing Transitions in Cardiovascular Care

Purpose of Review

The "fourth trimester" concept, defined as the first 12 weeks after delivery (and beyond), is a critical window of time for clinicians to intervene to optimize women's cardiovascular health after pregnancy. A timely and comprehensive postpartum cardiovascular assessment should be performed in all women following delivery in order to (1) follow up medical conditions present prior to conception, (2) evaluate symptoms and signs of common postpartum complications, and (3) identify risk factors and prevent future adverse cardiovascular outcomes. In this review, we aim to discuss major maternal cardiovascular risk factors such as hypertensive disorders of pregnancy, gestational diabetes mellitus, postpartum weight retention, and postpartum depression, as well as lactation as a potential protective risk modifying factor. Additionally, we will review effectiveness of outpatient interventions to enhance transitions in cardiovascular care during the fourth trimester.

Recent Findings

A seamless hand-off from obstetric to primary care, and potentially cardiology, is needed for early detection and management of hypertension, weight, glycemic control, stress and mood, and long-term cardiovascular risk. Additionally, the use of telemedicine, blood pressure self-monitoring, remote activity monitoring, and behavioral health coaches are potentially feasible modalities to augment clinic-based care for cardiovascular risk factors and weight management, but additional studies are needed to study their long-term effectiveness.

Summary

Development of a comprehensive postpartum care plan with careful consideration of each patient's risk profile and access to resources is critical to improve maternal morbidity and mortality, reduce health disparities, and achieve long-term cardiovascular health for women. Supporting postpartum well-being of women during this transition period requires a multidisciplinary approach, especially primary care engagement, and planning should start before delivery.

Contribution of environmental factors and female reproductive history to hypertension and obesity incidence in later life

BACKGROUND

Hypertension (HT) and obesity, which are important risk factors for cardiovascular diseases, are complex traits determined by multiple biological and behavioural factors. However, the role of female reproductive history in evaluating HT and obesity is still unclear.

AIM

To investigate the long-term effects of reproductive factors on the probability of obesity and HT in later life after adjusting for socio-demographic and lifestyle behaviour factors.

SUBJECTS AND METHODS

A total of 503 women (39 - 65 years) were recruited from different localities in Slovakia. Multivariable logistic regression analyses were performed to test the associations.

RESULTS

Early menarche age of 11 years and under was associated with twice higher probability of obesity at midlife, independent of environmental confounders (OR = 2.27, CI = 1.35 - 3.81, p = 0.002). Breastfeeding (Bf) women had a lower likelihood of obesity in later life than non-Bf parous women, independent of environmental confounders (OR = 0.35, CI = 0.17 - 0.72, p = 0.004). Finally, age at menarche was associated with obesity-associated HT.

CONCLUSION

Reproductive factors are significantly associated with obesity and obesity-associated HT in later life. The age at menarche and Bf can be risk factors for early identification of women with increased likelihood of adult cardiovascular risk.

Behaviour, Attitudes and Knowledge of Healthcare Workers on Breastfeeding

The aim of this paper is to determine the current state of behavior, attitudes, and knowledge of health professionals about breastfeeding in Croatia. Data were collected via a breastfeeding behavior, attitudes, and knowledge questionnaire, which has already been validated and used in Croatia. The secondary aim is to identify differences in outcomes of respondents by occupation (nurses versus others health professionals). In the study, 374 health professionals participated (37 males and 337 females). Respondents completed the questionnaire online. Respondents were rarely involved in breastfeeding education. On the behavior scale, the worst answer was given to the question of advising mothers on breastfeeding after 24 months. On the attitude scale, the worst result was achieved in terms of public breastfeeding and the support of the child's father for the breastfeeding mother. Respondents demonstrated the worst knowledge of The International Code of Marketing of Breast-milk Substitutes and the use of medications while breastfeeding. There was no statistically significant difference between the results of respondents in relation to the occupation of the respondents. In the preparation of future breastfeeding education for health professionals in Croatia, particular attention should be given to these issues.

The cardiovascular benefits of breastfeeding to mothers

Not applicable.

Polychlorinated dioxins and dibenzofurans (PCDD/F), polybrominated dioxins and dibenzofurans (PBDD/F), polychlorinated biphenyls (PCB), polybrominated diphenyl ethers (PBDE), and per- and polyfluoroalkyl substances (PFAS) in German breast milk samples (LUPE 8)

Most organic pollutants (POP) are persistent in the environment, accumulate in fatty tissues, and so a transfer through the food chain is probably, thereby causing various health effects. We quantified PCDD/F, PBDD/F, PCB, PBDE, perfluorinated substances, and ADONA in breast milk samples collected in two German federal states and breast milk and blood samples from subjects additionally exposed to PFOA. The median (95th percentile) concentrations were 2.43 (6.58) pgWHO₂₀₀₅TEQ/g l.w. for PCDD/F, 2.45 (4.82) pgWHO₂₀₀₅TEQ/g l.w. for dioxin-like PCB (dl-PCB), and 0.62 (2.69) pgWHO₂₀₀₅TEQ/g l.w. for PBDD/F. The relative contributions of the median values of PCDD/F, dl-PCB, and PBDD/F to the total-TEQ were approximately 41%, 42%, and 11%, respectively. Nondioxin-like PCB (ndl-PCB) concentrations were clearly dominated by the higher chlorinated PCB congeners, with medians of 23.2 ng/g l.w. for PCB 153, 13.9 ng/g l.w. for PCB 138, and 13.0 ng/g l.w. for PCB 180. The sum of the 3 congeners (PCB 138, 153, and 180) were multiplied with 1.64 (total PCB) and showed a median of 82.16 ng/g l.w. and a 95th percentile of 173.3 ng/g l.w. Only PFOA and PFOS could be quantified in 29% and 17% of in total 180 samples with 95th percentiles of 53 ng/l and 33 ng/l, respectively. Milk samples (n = 13) from subjects living on PFOA contaminated sites showed higher levels between 33 and 854 ng/l PFOA (mean: 199 ng/l), whilst PFOS could be quantified only in three samples. The sum of 17 PBDE congeners showed medians (95th percentile) of 1737 pg/g l.w. (22,806 pg/g l.w.), with the highest medians of 422 pg/g l.w. for BDE 209 and 378 pg/g l.w. for BDE 153. Overall, our study confirms the declining contamination level in breast milk during the last decade, but points out the need to further reduce the environmental contamination with persistent substances and subsequently the exposure in childhood.

Patterns and Predictors of Breast Milk Feeding from Birth to Age 4 Months among Primiparous African American Mother–Infant Dyads

The health benefits of breast milk feeding have been well-established, yet disparities exist, with African American mothers having the lowest breast milk feeding rates in the United States. This prospective, longitudinal study examined infant feeding (breast milk and/or infant formula) from birth to age 16 weeks, predictors of any breast milk feeding by age 1 week, and predictors of cessation of any breast milk feeding by ages 3, 8, and 16 weeks among primiparous African American mothers. This secondary analysis included 185 mother–infant dyads from the Sleep SAAF (Strong African American Families) study, a randomized clinical trial testing a responsive parenting vs. child safety control intervention. Mothers reported sociodemographic and psychosocial characteristics at age 1 week and infant feeding practices at ages 1, 3, 8, and 16 weeks. Rates of any breast milk feeding decreased from 66.5% at 1 week to 23.3% at 16 weeks. Bivariate logistic regression models showed that prepregnancy BMI (OR = 1.09), working prepregnancy (OR = 2.25), and food insecurity (OR = 2.49) significantly increased the odds of mothers feeding any breast milk by 1 week, whereas Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participation (OR = 0.21) significantly decreased the odds. Bivariate logistic regression models showed that Supplemental Nutrition Assistance Program (SNAP) participation (OR = 2.86) and racial discrimination (OR = 2.14) significantly increased the odds of cessation of any breast milk feeding by 3 weeks. SNAP (OR = 2.33) and WIC (OR = 2.38) participation significantly increased the odds of cessation of any breast milk feeding by 8 weeks, whereas higher prepregnancy BMI (OR = 0.95) decreased the odds. Higher mother’s age (OR = 0.92) significantly decreased the odds of cessation of any breast milk feeding by 16 weeks. The findings can be used to inform targeted interventions to promote mothers feeding any breast milk and help reduce breast milk feeding disparities among African American mothers.

Ethical Considerations for Hospital-Based Infant Feeding Support

I applied a systematic ethical decision-making approach to evaluate how health care professionals in hospital settings should provide infant feeding support after childbirth. Human milk is recommended as the optimal source of nutrition for infants because of the health benefits it provides for infants and their lactating parents. However, health consequences of insufficient oral intake in infants and psychological distress in the lactating parent may occur when infant feeding does not go according to plan. Infant feeding support should be provided in a way that is objective, sensitive, individualized, equitable, and supportive of autonomy and avoids harm. I provide recommendations for ethical infant feeding support that can be applied by individual health care professionals and on postpartum units in hospitals.

Exclusive breastfeeding among women with type 1 and type 2 diabetes mellitus

Objective

To compare exclusive breastfeeding (BF) and BF initiation among 185 women with Type 1 and 212 women with Type 2 pregestational diabetes who intended exclusive or partial BF and delivered at ≥34 weeks of gestation.

Methods

Retrospective cohort study. At discharge, exclusive BF is direct BF or BF complemented with expressed breast milk. BF initiation is defined by exclusive or partial BF.

Results

Type 1 and Type 2 groups were similar in prior BF experience (69 vs 67%) but were different in intention to BF exclusively (92 vs 78%) and partially (8 vs 22%). Women in the Type 1 group were younger (median age 30 vs 33y), likely to be primiparous (47 vs 25%), have a lower median BMI (32 vs 36 kg/m²) and deliver by primary cesarean (37 vs 26%). Infants born to Type 1 women were more likely to be admitted to the NICU (44 vs 18%) and to have hypoglycemia (59 vs 41%). At discharge, exclusive BF among Type 1 was higher (34 vs 23%), partial BF was similar (47 vs 46%) while FF (formula feeding) was lower (19 vs 31%) than in the Type 2 group. BF initiation occurred in 81% of Type 1 and 69% of Type 2 women.

Conclusion

Intention to BF exclusively was higher in Type 1 women compared to Type 2. At discharge, exclusive BF and BF initiation were lower and FF higher in the Type 2 group highlighting the need for different strategies if lactation in this special population is to be improved.

Associations of breastfeeding history with metabolic syndrome and cardiovascular risk factors in community-dwelling parous women: The Japan Multi-Institutional Collaborative Cohort Study

OBJECTIVE

The aim of the present study was to investigate the associations between breastfeeding and the prevalence of metabolic syndrome in community-dwelling parous women and to clarify whether the associations depend on age.

METHODS

The present cross-sectional study included 11,118 women, aged 35-69 years. Participants' longest breastfeeding duration for one child and their number of breastfed children were assessed using a self-administered questionnaire, and their total breastfeeding duration was approximated as a product of the number of breastfed children and the longest breastfeeding duration. The longest and the total breastfeeding durations were categorized into none and tertiles above 0 months. Metabolic syndrome and cardiovascular risk factors (obesity, hypertension, dyslipidemia, and hyperglycemia) were defined as primary and secondary outcomes, respectively. Associations between breastfeeding history and metabolic syndrome or each cardiovascular risk factor were assessed using multivariable unconditional logistic regression analysis.

RESULTS

Among a total of 11,118 women, 10,432 (93.8%) had ever breastfed, and 1,236 (11.1%) had metabolic syndrome. In participants aged <55 years, an inverse dose-response relationship was found between the number of breastfed children and the prevalence of metabolic syndrome; multivariable-adjusted odds ratios for 1, 2, 3, and ≥4 breastfed children were 0.60 (95% confidence interval [CI]: 0.31 to 1.17), 0.50 (95% CI: 0.29 to 0.87), 0.44 (95% CI: 0.24 to 0.84), and 0.35 (95% CI: 0.14 to 0.89), respectively. The longest and total breastfeeding durations of longer than 0 months were also associated with lower odds of metabolic syndrome relative to no breastfeeding history in participants aged <55 years. In contrast, all measures of breastfeeding history were not significantly associated with metabolic syndrome and cardiovascular risk factors in participants aged ≥55 years old.

CONCLUSIONS

Breastfeeding history may be related to lower prevalence of metabolic syndrome in middle-aged parous women.

Breastfeeding Is Associated With a Reduced Maternal Cardiovascular Risk: Systematic Review and Meta-Analysis Involving Data From 8 Studies and 1 192 700 Parous Women

Background

Breastfeeding has been robustly linked to reduced maternal risk of breast cancer, ovarian cancer, and type 2 diabetes. We herein systematically reviewed the published evidence on the association of breastfeeding with maternal risk of cardiovascular disease (CVD) outcomes.

Methods and Results

Our systematic search of PubMed and Web of Science of articles published up to April 16, 2021, identified 8 relevant prospective studies involving 1 192 700 parous women (weighted mean age: 51.3 years at study entry, 24.6 years at first birth; weighted mean number of births: 2.3). A total of 982 566 women (82%) reported having ever breastfed (weighted mean lifetime duration of breastfeeding: 15.6 months). During a weighted median follow‐up of 10.3 years, 54 226 CVD, 26 913 coronary heart disease, 30 843 stroke, and 10 766 fatal CVD events were recorded. In a random‐effects meta‐analysis, the pooled multivariable‐adjusted hazard ratios comparing parous women who ever breastfed to those who never breastfed were 0.89 for CVD (95% CI, 0.83–0.95; I²=79.4%), 0.86 for coronary heart disease (95% CI, 0.78–0.95; I²=79.7%), 0.88 for stroke (95% CI, 0.79–0.99; I²=79.6%), and 0.83 for fatal CVD (95% CI, 0.76–0.92; I²=47.7%). The quality of the evidence assessed with the Grading of Recommendations Assessment, Development, and Evaluation tool ranged from very low to moderate, which was mainly driven by high between‐studies heterogeneity. Strengths of associations did not differ by mean age at study entry, median follow‐up duration, mean parity, level of adjustment, study quality, or geographical region. A progressive risk reduction of all CVD outcomes with lifetime durations of breastfeeding from 0 up to 12 months was found, with some uncertainty about shapes of associations for longer durations.

Conclusions

Breastfeeding was associated with reduced maternal risk of CVD outcomes.

Breastfeeding initiation among women with chronic hypertension superimposed on pregestational diabetes mellitus

OBJECTIVE

To compare breastfeeding (BF) initiation among 317 women with chronic hypertension (CHTN) and 106 women with CHTN superimposed on pregestational diabetes (CHTN-DM) who intended exclusive or partial BF.

METHODS

Retrospective cohort study of women who delivered at≥34 weeks of gestation. At discharge, exclusive BF was defined by direct BF or BF complemented with expressed breast milk (EBM) while partial BF was defined by formula supplementation.

RESULTS

CHTN and CHTN-DM groups were similar in prior BF experience (42 vs 52%), intention to BF exclusively (89 vs 79%) and intention to partially BF (11 vs 21%). Women in the CHTN group were younger (31 vs 33y), more likely primiparous (44 vs 27%), and delivered vaginally (59 vs 36%) at term (85 vs 75%). Women in the CHTN-DM group had higher repeat cesarean rates (32 vs 18%), preterm birth (25 vs 15%), neonatal hypoglycemia (42 vs 14%) and NICU admission (38 vs 16%). At discharge, exclusive BF rates among CHTN was higher (48 vs 19%), while rates of partial BF (34 vs 44%) and FF (18 vs 37%) were lower than in the CHTN-DM group. BF initiation (exclusive plus partial BF) occurred in 82%of CHTN and in 63% of CHTN-DM.

CONCLUSION

Although intention to BF was similar, BF initiation rates were higher for the CHTN compared to the CHTN-DM group. Exclusive BF was low in the CHTN and even lower in the CHTN-DM group signaling the need for targeted interventions if BF initiation rates are to be improved.

Reproductive factors and breast arterial calcification: a systematic review and meta-analysis

BACKGROUND

Breast arterial calcification (BAC) is a common incidental finding on screening mammography. Recent evidence suggests that BAC is associated with cardiovascular disease (CVD). We systematically reviewed the associations between BAC and reproductive factors (menopausal status, hormone replacement therapy [HRT] use, oral contraceptive [OC] use and parity).

METHODS

MEDLINE and EMBASE databases, references of relevant papers and Web of Science were searched up to February 2020 for English-language studies that evaluated these associations. Study quality were determined and a random effects model was used to assess these associations.

RESULTS

Nineteen observational studies (n = 47,249; three cohort studies, seven case-control studies, nine cross-sectional studies) were included. BAC was associated with menopause (nine studies; n = 15,870; odds ratio [OR] 2.67; 95% confidence interval [CI] 1.50-4.77) and parity (seven studies; n = 27,728; OR 2.50; 95% CI 1.68-3.71) and inversely with HRT use (10 studies; n = 33,156; OR 0.57; 95% CI 0.40-0.80). No association was found with OC use. Eleven studies were considered good in quality. Marked heterogeneity existed across all analyses.

CONCLUSIONS

BAC is associated with HRT use, menopause and parity. However, careful interpretation is required as marked heterogeneity existed across all analyses. Traditional cardiovascular risk factors may need to be taken into account in future investigations of associations between BAC and reproductive factors.

Association of prenatal medical risk with breastfeeding outcomes up to 12 months in the All Our Families community-based birth cohort

Background

Prenatal medical risk describes physical health issues or biological factors that predate or arise during pregnancy which heighten the risk of adverse outcomes, and often warrant specialized obstetric care. The influence of the nature and magnitude of prenatal risk on breastfeeding outcomes remains poorly understood. The objective of this study was to determine the association between prenatal medical risk and breastfeeding initiation and duration up to 1 year postpartum.

Methods

We analysed a subset of data from the All Our Families longitudinal cohort (n = 2706) of women in Calgary, Canada who delivered a liveborn infant between 2008 and 2010. Data were collected from self-report questionnaires and medical records. Women with complete data on prenatal medical risk factors and breastfeeding outcomes were included in this analysis. Prenatal medical risk was operationalized as one integer score of risk severity and four binary risk types capturing pre-pregnancy characteristics, past obstetric problems, current obstetric problems, and substance use. Outcomes were breastfeeding initiation defined as the infant ever receiving breast milk, and duration operationalized as still breastfeeding at 4 months, at 12 months, and time to breastfeeding cessation in weeks. We used logistic regression and Cox regression with right censoring at 52 weeks or attrition to calculate odds ratios (OR) and hazard ratios (HR), respectively, adjusting for sociodemographic vulnerability, parity, mode of delivery, and gestational age.

Results

Prenatal medical risk severity and type were not significantly associated with breastfeeding initiation, with the exception of pre-pregnancy risk type (OR 0.45; 95% CI 0.26, 0.77). Risk severity was associated with lower odds of breastfeeding to 4 months (OR 0.94; 95% CI 0.90, 0.99), 12 months (OR 0.93; 95% CI 0.87, 0.98), and earlier breastfeeding cessation (HR 1.05; 95% CI 1.02, 1.08). Associations with shorter breastfeeding length across the first postpartum year were observed for pre-pregnancy, current obstetric, and substance use risk types, but not past obstetric problems.

Conclusion

Prenatal medical risk is associated with shortened duration of breastfeeding. Women with prenatal medical risk may benefit from the proactive arrangement of lactation support before and following delivery to promote continued breastfeeding.

Breastfeeding knowledge in university nursing students. A multicentre study in Spain

BACKGROUND

Exclusive breastfeeding is one of the main health and infant survival elements. To start and maintain breastfeeding, health professionals must receive culturally sensitive evidence-based breastfeeding training to offer future mothers the required information and support. While studying the nursing degree, acquiring the necessary knowledge and skills to successfully perform this work is essential.

OBJECTIVE

Study the level of nursing students' breastfeeding knowledge at three Spanish public universities; explore which variables are related to acquire this knowledge.

DESIGN

An observational, descriptive, cross-sectional multicentre study.

METHODS

Participants were the students registered for the 4 nursing degree years at the three participating universities (N = 1540). They were asked about their breastfeeding knowledge with the self-administered AprendeLact Questionnaire; breastfeeding-related socio-demographic variables were included.

RESULTS

The overall mean score of the 684 returned questionnaires was 4.659 (±2.377) out of 10. The year-4 students from the Castellón university obtained significantly higher mean scores and had been on practicals in maternity or neonatology units, belonged to breastfeeding associations and were artificially fed as infants. University belonged to, current academic year and placements in maternity or neonatology units were relevant factors for acquiring breastfeeding knowledge.

CONCLUSIONS

Syllabi based on progressive transversal learning, and participating in real maternity-related health settings, could be facilitating strategies to acquire a suitable level of breastfeeding knowledge.
