Infant feeding practices and body mass index up to 7.5 years in the French nationwide ELFE study.

BACKGROUND/OBJECTIVES: The infant diet represents one of the main modifiable determinants of early growth. This study aimed to investigate the associations of infant feeding practices with body mass index (BMI) until 7.5 years. SUBJECTS/METHODS: Analyses were based on data from the French nationwide ELFE birth cohort. Data on breastfeeding (BF) and complementary feeding (CF) were collected monthly from 2 to 10 months. Infant feeding practices were characterized using principal component analyses (PCA) and hierarchical ascendant classification. BMI z-score was computed at 1, 2, 3, 5 and 7.5 years, from data collected in the child's health booklet; 7.5-year overweight was defined according to IOTF references. Associations between infant feeding practices and BMI were investigated by linear regression models adjusted for main confounders. RESULTS: Ever breastfeeding was not associated with BMI up to 7.5 years. Compared to intermediate breastfeeding duration (1 to <3 months), longer breastfeeding duration (≥6 months) was related to lower 1-year BMI, but not at older ages. Compared to the recommended age at CF introduction (4-6 months), early CF (<4 months) was related to higher BMI up to 5 years with a similar trend at 7.5 years, but not to the risk of overweight. The PCA patterns characterized by early baby cereal introduction and late food pieces introduction or by frequent intake of main food groups were related to a lower BMI up to 7.5 years. CONCLUSION: Breastfeeding was related with a lower BMI in infancy but not thereafter, whereas an early CF initiation (<4 months) was associated with a higher BMI in childhood.

The Rights of Physicians and Future Physicians Who Are Lactating, Breastfeeding, or Chestfeeding: An American Medical Women's Association Position Article.

Breastfeeding is a fundamental and biologically normal function with well-established benefits for both lactating parents and infants. Despite these benefits, physicians, particularly those in training, often face significant obstacles when attempting to meet their breastfeeding and pumping goals. In response to these challenges, the American Medical Women's Association (AMWA) and a diverse group of health care professionals have come together to advocate for comprehensive lactation support policies in medical learning environments and workplaces. This position article highlights the ethical necessity of comprehensive lactation support in medical educational and workplace settings, emphasizing the importance of not only providing physical accommodations but also fostering a cultural shift, educational initiatives, and policy reforms to empower lactating parents. It offers an examination of the difficulties encountered by lactating parents within medical environments and proposes guidelines for the formulation and enhancement of supportive policies. The position article envisions a future where medical professionals can thrive in both their careers and parenthood through collaborative efforts and a commitment to the key elements of Effective Lactation Support Programs in medical workplaces based on the following: (1) well-equipped lactation facilities, (2) customized work schedules, (3) mentorship and support networks, (4) lactation support in clinical settings, and (5) research and advocacy.

Theory-based antecedents of breastfeeding among pregnant women in the United States.

Background: Breastfeeding provides several positive health benefits for the newborn child, yet breastfeeding rates remain low in the United States (US). Theory-based approaches have the potential to improve breastfeeding promotion interventions. Hence, the study examined the correlates of intention to breastfeed among US pregnant women based on the multi-theory model (MTM) of health behavior change. Methods: Using a cross-sectional design, a 36-item online survey was administered to a nationally representative sample of 315 pregnant women in the US. The instrument was psychometrically validated for face, content, and construct validity by a panel of six experts over two rounds. Further, construct validation was done by confirmatory factor analysis (CFA). Hierarchical regression modeling was employed to explain the intention to start breastfeeding and sustain exclusive breastfeeding for up to six months and with complementary foods for up to 24 months. Results: Internal consistency using Cronbach's alpha was found to be acceptable. It was found that behavioral confidence and changes in the physical environment positively affected the initiation of breastfeeding (P<0.01; adjusted R2=0.478). All three constructs of MTM namely practice for change, emotional transformation, and changes in the social environment were significant predictors for the sustenance of breastfeeding at six months (P<0.01; adjusted R2=0.591) and at 24 months (P<0.01; adjusted R2=0.347). Conclusion: Based on the findings of this study it is essential for educators and healthcare providers to design MTM-based interventions to promote breastfeeding among pregnant women in the US.

Assessment of breast-feeding and weaning practices of under-fives and their associated co-morbidities in urban and rural areas of Ahmedabad City, Gujarat, India.

Introduction: Shaping up the post-2015 development agenda is of crucial importance in the development process around the Globe as 20151 was the last year of milllenium development goals. It is the right time to asses our own progress vis-a-vis the Millennium development goals. Appropriate feeding and weaning practices are the key contributor for decreasing morbidities and mortalities in under-five children. As per national family health survey-5 (NFHS-5), only 55.8% of the Indian infants between 0 and 6 months were exclusively breastfed in Gujarat. Children age 6-8 months receiving solid or semi-solid food and breast milk were only 49.4% in Gujarat. Only 5.8% of breastfeeding infants aged 6-23 months receive an adequate diet in Gujarat. Hence the following study was done to know the practice of breastfeeding and weaning in mothers of urban and rural area of Ahmedabad city, Gujarat. Objective: The primary objective of this study was to describe the breastfeeding and newborn care practices and the factors affecting the initiation and duration of breastfeeding in urban and rural areas of Ahmedabad city, Gujarat and the secondary objective was to describe the comorbidities associated with them. Methods: Cross-sectional study was done in anganwadis of slums of urban and rural field practice area of B.J. Medical College, Ahmedabad. Results: Half of the under-five children were provided jaggery as pre-lacteal feed both in urban (45%) and rural (53%) area. In urban area most common reason for providing pre lacteal feeds was due to family customs (55%) followed by their belief that it leads to help in removal of meconium from gut (22%) followed by as advised from their relatives (23%) as compared to in rural area where there was belief that it leads to help in removal of meconium from gut (52%) followed by family customs (31%) and advise from relatives (17%). There were 7.5% under-five children in urban area in whom breastfeeding was not initiated immediately compared to rural area in which there were 42% under-five children. Conclusion: Frequent occurrence of acute illness among under-fives may have lead to undernutrition.

Inequality in breastfeeding and complementary feeding practices in Argentina by household income level in 2018-2019. / Desigualdad en las prácticas de lactancia y alimentación complementaria en la Argentina, según nivel de ingresos del hogar en 2018-19.

Introduction. Diet quality is a right related to survival, healthy growth, prevention of chronic diseases, and malnutrition in all its forms. The objective of this study was to analyze breastfeeding and feeding practices in children younger than 2 years from urban areas of Argentina in 2018-2019 according to their household income level. Population and methods. Secondary analysis of data of the Second National Survey on Nutrition and Health (ENNyS2) of 2018-2019. Breastfeeding and complementary feeding indicators proposed by the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) were analized. Data were stratified by household income level. Results. The analysis included 5763 children younger than 24 months old. Although 97% was ever breastfed, only 47% of infants younger than 6 months were exclusively breastfed the previous day and 48% continued with breastfeeding after 1 year old, with a higher prevalence in low-income children. The previous day, 23% of children aged 6 to 23 months did not eat any fruit or vegetable, 60% consumed unhealthy foods, and 50% consumed sweet beverages. The consumption of sweet beverages and the absence of fruit and vegetables were higher in low-income households. Conclusion. The quality of children's diet is far from the recommendations and is conditioned by income. Early initiation of breastfeeding, minimum dietary diversity, fruit and vegetable consumption are lower and sweet beverage consumption is greater in impoverished sectors.

Introducción. La calidad de la alimentación es un derecho vinculado con la supervivencia, el crecimiento saludable, la prevención de enfermedades crónicas y malnutrición en todas sus formas. El objetivo de este trabajo fue analizar las prácticas de lactancia y de alimentación de menores de 2 años de áreas urbanas de la Argentina en 2018-19, según el nivel de ingreso de los hogares. Población y métodos. Estudio secundario con datos de la 2.a Encuesta Nacional de Nutrición y Salud 2018-19. Se analizaron indicadores de lactancia y alimentación complementaria, según metodología de la Organización Mundial de la Salud (OMS) y Unicef. Se estratificó según nivel de ingresos del hogar. Resultados. El análisis incluyó 5763 menores de 24 meses. Aunque el 97 % fue alguna vez amamantado, solo el 47 % de los menores de 6 meses tuvo lactancia exclusiva el día previo y el 48 % mantenía la lactancia luego del año, con mayor prevalencia en los niños/as de menores ingresos. En el día previo, el 23 % de los niños/as de 6 a 23 meses no consumió ninguna verdura o fruta; el 60 % consumió alimentos no saludables y el 50 %, bebidas dulces. Las bebidas dulces y la ausencia de frutas y verduras fueron mayores en aquellos de hogares de menores ingresos. Conclusión. La calidad de la alimentación de los niños/as dista de las recomendaciones y está condicionada por los ingresos. En los sectores empobrecidos, es menor el inicio temprano de la lactancia, la diversidad alimentaria mínima y el consumo de frutas y verduras, y es mayor el consumo de bebidas dulces.

Is maternal body weight or composition associated with onset of lactogenesis II, human milk production or infant consumption of mother's own milk? A systematic review and meta-analysis.

Maternal adiposity impacts lactation performance, but the pathways are unclear. We conducted a systematic review to understand whether maternal adiposity (body mass index [BMI] or % fat mass) is associated with onset of lactogenesis II (copious milk; hours), human milk production (expressed volume/24hrs), and infant consumption of mother's own milk (volume/24hrs). We used random-effects standard meta-analyses to compare the relative risk (RR) of delayed lactogenesis II (>72 hours) between mothers classified as underweight (BMI <18.5kg/m2), healthy weight (BMI 18.5-24.9 kg/m2), and overweight/obese (BMI >25kg/m2) and random-effects meta-regressions to examine associations with hours to lactogenesis II and infant milk consumption. The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation approach. We included 122 articles. Mothers with underweight (RR: 0.61; 95% CI: 0.46, 0.83; I2= 46.27%; 8 articles/datapoints) or healthy weight status (RR: 0.72; 95% CI: 0.61, 0.84; I2= 64.41%; 15 articles/datapoints) were less likely to experience delayed lactogenesis II than mothers with overweight/obesity. We found no association between maternal BMI and time onset of lactogenesis II (ß= 1.45 hours; 95% CI: -3.19, 6.09; p= 0.52, I2= 0.00%; 8 articles, 15 datapoints). Due to limited data, we narratively reviewed articles examining BMI or % fat mass and milk production (n=6); half reported an inverse association, and half no association. We found no association between maternal BMI (ß= 5.84mL; 95% CI: -11.92, 23.60; p= 0.51, I2= 44.18 %; 58 articles, 75 datapoints) nor % fat mass (ß= 6.54mL; 95% CI: -3.60, 16.68; p= 0.20, I2= 21.40%; 30 articles, 32 datapoints) and infant milk consumption. Certainty of evidence for all outcomes was very low. In conclusion, mothers with overweight/obesity may be at risk of delayed lactogenesis II. Available data do not support an association with infant milk consumption but included studies do not adequately represent mothers with obesity. PROSPERO REGISTRATION #: 285344 STATEMENT OF SIGNIFICANCE: While results suggest mothers with overweight/obesity may be at risk of delayed lactogenesis II, it is important to note that available data do not adequately represent mothers at the higher end of the BMI and % fat mass spectrum (BMI >30 kg/m2, % fat mass >40%). Future research should explore the association between maternal body weight or composition and lactation outcomes including onset of lactogenesis II, human milk production and infant consumption of mother's own milk among mothers with greater variability in weight status. Understanding these relationships may help guide the creation of more specialized lactation care for mothers of all body sizes.

[Evaluation of the satisfaction of healthcare professionals using the CRAT website, and launch of a new version]. / Évaluation de la satisfaction des professionnels de santé utilisateurs du site internet du CRAT et lancement d'une nouvelle version.

In preparation for a new version of the CRAT (Centre de référence sur les agents tératogènes) website, an evaluation of user satisfaction was carried out. An invitation to complete an online questionnaire covering the various dimensions of the website (appearance, content, interactivity, ease of use, technical performance) was sent in April 2022 to healthcare professionals who referred to CRAT for clinical expertise over the previous two years. After sending out 3224 individual e-mail invitations, 758 evaluators completed the questionnaire in full (response rate: 23.5%). The evaluation revealed a high-level of overall satisfaction among site users (98.0% very satisfied or satisfied). Satisfaction with the site's appearance was also high, although comments were made about the site's lack of a modern web design. Health professionals recognized in their responses the reliable, relevant and up-to-date nature of the content of this free, public online resource, independent of the pharmaceutical industry. On the basis of these highly favorable assessments, with content that has been widely acclaimed and areas for improvement that have caught the attention of site users (evolution of its appearance, of the search tool, implementation of a mobile site), a new version of www.lecrat.fr was launched in the fall of 2023.

Enrollment and use of a peer counselor mHealth texting program to support breastfeeding in low-income people: A pilot study in the District of Columbia.

OBJECTIVE: To describe the characteristics of postpartum people who did and did not enroll in a breastfeeding peer-counselor mobile health (mHealth) texting program as well as the issues raised through 2-way texting with peer counselors. DESIGN: Pilot intervention study involving two Special Supplemental Nutrition Programs for Women Infants and Children (WIC) sites in the District of Columbia over 1 year. SAMPLE: WIC recipients. MEASUREMENTS: Descriptive statistics, comparison of recipients who enrolled or not and qualitative content analysis of text messages. INTERVENTION: A breastfeeding peer counselor texting program entitled BfedDC involving routine 1-way programmed messages and 2-way texting capacity for recipients to engage with peer counselors. RESULTS: Among our sample (n = 1642), nearly 90% initiated breastfeeding. A total of 18.5% (n = 304) enrolled in the BfedDC texting program, of whom 19.7% (n = 60) utilized the 2-way texting feature. Message content covered seven content themes and included inquiries about expressing human milk, breastfeeding difficulties, breastfeeding frequency and duration, appointments and more. CONCLUSIONS: Although enrollment was relatively low in BfedDC, benefits included 1-way supportive texts for breastfeeding and the ability to 2-way text with peer counselors. This program aligns with the Surgeon General's Call to Action to Support Breastfeeding and promotes breastfeeding equity in low-income people.

Effectiveness of a Postpartum Breastfeeding Support Group Intervention in Promoting Exclusive Breastfeeding and Perceived Self-Efficacy: A Multicentre Randomized Clinical Trial.

There are numerous recognized benefits of breastfeeding; however, sociocultural, individual, and environmental factors influence its initiation and continuation, sometimes leading to breastfeeding rates that are lower than recommended by international guidelines. The aim of this study was to evaluate the effectiveness of a group intervention led by midwives supporting breastfeeding during the postpartum period in promoting exclusive breastfeeding, as well as to assess the impact of this intervention on perceived self-efficacy. This was a non-blind, multicentric, cluster-randomized controlled trial. Recruitment started October 2021, concluding May 2023. A total of 382 women from Andalusia (Spain) participated in the study. The results showed that at 4 months postpartum there was a higher prevalence of breastfeeding in the intervention group compared to formula feeding (p = 0.01), as well as a higher prevalence of exclusive breastfeeding (p = 0.03), and also at 6 months (p = 0.01). Perceived self-efficacy was similar in both groups for the first two months after delivery, which then remained stable until 4 months and decreased slightly at 6 months in both groups (p = 0.99). The intervention improved the average scores of perceived self-efficacy and indirectly caused higher rates of exclusive breastfeeding (p = 0.005). In conclusion, the midwife-led group intervention supporting breastfeeding proved to be effective at maintaining exclusive breastfeeding at 6 months postpartum and also at increasing perceived self-efficacy.

A Stress Reduction Intervention for Lactating Mothers Alters Maternal Gut, Breast Milk, and Infant Gut Microbiomes: Data from a Randomized Controlled Trial.

BACKGROUND: This secondary analysis of data from a randomized controlled trial (RCT) investigated how the maternal gut, breast milk, and infant gut microbiomes may contribute to the effects of a relaxation intervention, which reduced maternal stress and promoted infant weight gain. METHODS: An RCT was undertaken in healthy Chinese primiparous mother-infant pairs (340/7-376/7gestation weeks). Mothers were randomly allocated to either the intervention group (IG, listening to relaxation meditation) or the control group (CG). Outcomes were the differences in microbiome composition and the diversity in the maternal gut, breast milk, and infant gut at 1 (baseline) and 8 weeks (post-intervention) between IG and CG, assessed using 16S rRNA gene amplicon sequencing of fecal and breastmilk samples. RESULTS: In total, 38 mother-infant pairs were included in this analysis (IG = 19, CG = 19). The overall microbiome community structure in the maternal gut was significantly different between the IG and CG at 1 week, with the difference being more significant at 8 weeks (Bray-Curtis distance R2 = 0.04 vs. R2 = 0.13). Post-intervention, a significantly lower α-diversity was observed in IG breast milk (observed features: CG = 295 vs. IG = 255, p = 0.032); the Bifidobacterium genera presented a higher relative abundance. A significantly higher α-diversity was observed in IG infant gut (observed features: CG = 73 vs. IG = 113, p < 0.001). CONCLUSIONS: The findings were consistent with the hypothesis that the microbiome might mediate observed relaxation intervention effects via gut-brain axis and entero-mammary pathways; but confirmation is required.

Consumption of cow's milk formula in the nursery and the development of milk allergy.

BACKGROUND: The effect of the amount of transient cow's milk formula (CMF) consumed during the first days of life on IgE-cow's milk allergy (IgE-CMA) is unknown. METHODS: A cohort of 58 patients with IgE-CMA was identified from a large scale population-based study of 13,019 infants followed from birth. A group of 116 infants matched for sex and breastfeeding only duration (beyond the nursery period), and another random group of 259 healthy infants were used as controls. Parents were interviewed and the infants' medical records were searched to assess CMF consumption in the nursery. RESULTS: While 96% of the mothers of the 174 infants (58 with Cow's milk allergy and 116 controls) reported on exclusive breastfeeding during the stay in the nursery, CMF consumption was documented in 96 (55%) of the infants. Of those, most (57; 59%) received one to three feedings, 20 (21%) received four to nine feedings, and 19 (20%) received ≥10 feedings. Fewer formula feeds (1-3) were significantly more common in the allergic group than ≥4 feeds (p = 0.0003) and no feeds at all (p = 0.02) compared to controls (n = 116). Of those exclusively breastfed in the nursery, 13/23 allergic infants (57%) introduced CMF at age 105-194 days (the period with highest-risk for IgE-CMA) compared to 33/98 (34%) from the random control group (n = 259) (p = 0.04). CONCLUSIONS: Most infants end up receiving few CMF feeds in the nursery. Transient CMF in the nursery is associated with increased risk of IgE-CMA.

Plasma sphingomyelins and carnitine esters of infants consuming whole goat or cow milk-based infant formulas or human milk.

BACKGROUND: Infant formulas are typically manufactured using skimmed milk, whey proteins, and vegetable oils, which excludes milk fat globule membranes (MFGM). MFGM contains polar lipids including sphingomyelin (SM). OBJECTIVE: Comparison of infant plasma SM and acylcarnitine species between infants who are breastfed or receiving infant formulas with different fat sources. METHODS: In this explorative study we focused on SM and acylcarnitine species concentrations measured in plasma samples from the TIGGA study (ACTRN12608000047392), where infants were randomized to receive either a cow milk-based infant formula (CIF) with vegetable oils only or a goat milk-based infant formula (GIF) with a goat milk fat (including MFGM) and plant oil mixture at least up to the age of 4 months. Breastfed infants were followed as a reference group. Using tandem mass spectrometry, SM species in the study formulas and SM and acylcarnitine species in plasma samples collected at the age of four months were analyzed. RESULTS: Total SM concentrations (around 42 µmol/L) and patterns of SM species were similar in both formulas. The total plasma SM concentrations were not different between the formula groups, but were 15 % (CIF) and 21% (GIF) lower in the formula groups than in the breast fed group. Between the formula groups, differences in SM species were statistically significant but small. Total carnitine and major (acyl) carnitine species were not different between the groups. CONCLUSIONS: The higher total SM concentration in breastfed than in formula-fed infants might be related to a higher SM content in human milk, differences in cholesterol metabolism, dietary fatty acid intake or other factors not yet identified. SM and acylcarnitine species composition in plasma is not closely related to the formula fatty acid composition.

Protective effect of breastfeeding on Kawasaki disease: A systemic review and meta-analysis.

BACKGROUND: Previous research has indicated a negative correlation between exclusive breastfeeding and the incidence of Kawasaki disease (KD). However, the validation of this discovery through meta-analytical studies has been lacking. Furthermore, uncertainties persist regarding whether breastfeeding reduces the risk of coronary artery lesions (CAL) or resistance to intravenous immunoglobulin (IVIG). METHODS: A systematic exploration of the MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, and ClinicalTrials.gov databases was conducted to identify longitudinal or randomized controlled trials investigating the efficacy of breastfeeding in preventing KD. The primary focus was on the incidence of KD, with secondary emphasis placed on the incidence of CAL and IVIG resistance. Data were pooled using a frequentist-restricted maximum-likelihood random-effects model. RESULTS: Of the 179 potentially eligible studies identified, five (n = 1,982,634) were included. The analysis revealed a significantly lower risk of KD (expressed as odds ratio, with 95% confidence intervals and p-values) in comparisons between exclusive breastfeeding and formula feeding (0.62, 0.43-0.91, p = 0.014), exclusive breastfeeding/partial breastfeeding and formula feeding (0.66, 0.46- 0.96, p = 0.03), and exclusive breastfeeding and partial breastfeeding/formula feeding (0.81, 0.74- 0.90, p < 0.01). However, no significant difference was observed in the risk of developing KD when comparing partial breastfeeding to formula feeding exclusively. Regarding secondary outcomes, no statistically significant difference was found in the risk of CAL or IVIG resistance across any comparison formats. CONCLUSIONS: Our study suggests that breastfeeding correlated with a reduced risk of KD but not with a reduced risk of CAL or IVIG resistance. These findings advocate for the implementation of breastfeeding policies in clinical practice.

The interplay between emotional and breastfeeding difficulties in first-time mothers.

AIM/BACKGROUND: Both mental maternal health and breastfeeding difficulties impact maternal and infant health. The present study analyses the association between psychosocial and breastfeeding variables and maternal mental health. DESIGN/METHODS: The participants were 107 first-time mothers from Chile. Sociodemographic variables and breastfeeding difficulties were assessed at 6 weeks postpartum. Depression and anxiety symptoms, parental self-efficacy, and perceived social support were measured using validated, self-report questionnaires at 6 weeks and 5 months postpartum. This study is a secondary analysis of an intervention trial. RESULTS: 76% of the women reported having experienced some breastfeeding difficulty in the first postpartum weeks. The number of breastfeeding difficulties was associated with maternal mental health symptoms at 6 weeks postpartum and parental self-efficacy at both assessment times. Women who did not experience breastfeeding difficulties presented significantly fewer depressive (t(102) = 2.5, p = .015) and anxiety symptoms (t(50) = 2.3, p = .028) at 6 weeks postpartum than those who did. Mothers who exclusively breastfed at 5 months postpartum presented significantly higher parental self-efficacy (t(94) = 2.4, p = .044). A higher number of breastfeeding difficulties and low perceived social support contributed to higher depressive symptoms (R2 = .30; F(3,103) = 14.6, p < .001), anxiety symptoms (R2 = .32, F(3.103) = 17.27, p < .001) and lower parental self-efficacy at 6 weeks postpartum (R2 = .39; F(2,103) = 9.4, p < .001). CONCLUSION: Breastfeeding difficulties and social support are associated with fewer mental health symptoms and higher parental self-efficacy during early postpartum in first-time mothers.

Factors Associated with Low Volumes of Mother's Own Milk at Neonatal Intensive Care Unit Discharge of Very Low Birth Weight Infants-a Cohort Study.

Background: Mother's own milk (MOM) provides health benefits for infants with very low birth weight (VLBW). This study aimed to describe the incidence and factors associated with low volumes of MOM (<50% of total diet volume) at discharge for VLBW infants. Methods: A prospective cohort study of infants with VLBW and gestational age of <30 weeks, who survived to discharge and had no contraindication to MOM. We conducted bivariate analyses to investigate associations with the volume of MOM at discharge, using chi-square, t, and Mann-Whitney tests. All p-value analyses were two-tailed. The variables significantly associated with "low volumes of MOM" entered the multivariable analysis. Univariate and multivariate relative risk (confidence interval [CI] 95%) estimates were obtained from Poisson regression with a robust estimate of variance and controlled by the length of hospital stay. Results: Of 414 infants included and followed until discharge, 32.9% (n = 136) received less than 50% of the total daily volume of MOM. This outcome was associated with gestational age <28 weeks, lower birth weight, multiple births, developing bronchopulmonary dysplasia, and longer lengths of stay. After Poisson regression, low volumes of MOM at discharge were associated only with being born multiples (RR 2.01; CI 95% 1.53-2.64, p < 0.001) and with longer length of stay (RR 1.07; CI 95% 1.01-1.14, p = 0.01). Conclusions: Most VLBW infants were discharged home receiving predominantly MOM. Each neonatal intensive care unit (NICU) should acknowledge which clinical characteristics of mothers and VLBW infants are associated with difficulties maintaining MOM volumes until discharge.

[Prevalence of and risk factors for perceived absence of breast milk supply in Chinese lactating women in 2013].

OBJECTIVE: To investigate the prevalence and influencing factors of postpartum perceived absence of breast milk supply among Chinese mothers in 2013. METHODS: This is a cross-sectional study based on the data collected from children and mothers under 2 years of age in 2013 as part of the nutrition and health surveillance of Chinese residents. In this study, multistage stratified cluster sampling method was used to select subjects from 55 countires/districts in 30 provinces in China. The perceived absence of breast milk supply was defined as the mother's self-reported absence of breast milk and failure to breastfeed. Breastfeeding knowledge, maternal breastfeeding knowledge and general characteristics were collected through a structured questionnaire. Univariate analysis and Logistic regression were used to analyze the factors associated with perceived absence of breast milk supply. RESULTS: A total of 12091 mothers were included in the study, including 419 in the perceived non-breastfeeding group, the prevalence of perceived absence of breast milk supply was 3.5%. Multivariate Logistic regression showed maternal age(OR=1.04, 95%CI 1.02-1.06), postpartum hemorrhage(OR=2.03, 95%CI 1.30-3.16), and belief that breastfeeding should continue beyond 12 months of age(OR=0.27, 95%CI 0.17-0.45), not knowing how to breastfeed(OR=3.31, 95%CI: 2.31-4.74) were the main influencing factors for perceived absence of breast milk supply after delivery. CONCLUSION: Age, postpartum hemorrhage and knowledge level of breastfeeding are the main risk factors for perceived absence of breast milk supply, and knowledge level of breastfeeding is a modifiable factor.

From womb to world: mapping gut microbiota-related health literacy among Italian mothers, a cross-sectional study.

BACKGROUND: The gut microbiota is a key determinant of long-term health. Promoting maternal health literacy may enhance children well-being. Aim of the present study was to assess gut microbiota-related health literacy of Italian women and identify potential gaps in awareness. METHODS: A cross-sectional survey study was conducted using an online questionnaire (17 questions) on determinants and long-term impact of infant gut microbiota. The survey targeted Italian pregnant women and mothers of children under 2 years old, and was distributed through various social media channels between September 28th and November 15th, 2022. A total score was calculated as the sum of positive answers. Data on demographics, pregnancy status, and pre-existing knowledge of the infant gut microbiota were also collected. Descriptive and inferential statistics were applied. RESULTS: The questionnaire was completed by 1076 women. Median total score was 9 [7-11]. The 81.7% of respondents declared prior knowledge of the gut microbiota. The internet was among the most commonly cited primary sources of information. Independent predictors of total score were having a university degree (B = 0.656, p = 0.002) and prior knowledge (B = 2.246, p < 0.001). Conversely, older age was associated with lower total scores (B = -0.092, p < 0.001). The least known determinants of infant gut microbiota were gestational BMI, prematurity, mode of delivery and NICU stay. Pregnant women failed to recognize the role of breastfeeding in the development of infant gut microbiota more frequently than non-pregnant women. The 97.5% of participants reported increased interest in the gut microbiota, with heightened interest associated with prior knowledge. CONCLUSIONS: Our study revealed a moderate level of knowledge about infant gut microbiota among respondents, emphasizing the positive impact of prior knowledge on understanding and interest. Targeted educational interventions are needed to address awareness gaps, especially concerning the influence of breastfeeding on infant gut microbiota. Healthcare providers have the potential to enhance women's knowledge and awareness of this topic.

Association between postpartum depression and breastfeeding self-efficacy in mothers: a systematic review and meta-analysis.

BACKGROUND: Depression is one of the most common mental disorders in the postpartum period. Depression can decrease self-efficacy in breastfeeding by reducing the mother's self-confidence. Considering the conflicting results regarding the relationship between postpartum depression and breastfeeding self-efficacy, this systematic review was conducted to investigate the relationship between breastfeeding self-efficacy and postpartum depression. METHOD: In this systematic review, published articles in PubMed, Scopus, Web of Sciences, Cochrane Library, and Google Scholar databases were searched using English keywords "Self-efficacy, breastfeeding, breastfeeding Self-efficacy, depression, postpartum depression" without publication date limit. Data analysis was done with employing STATA14 software. Heterogeneity was assessed using I2 index which was 0%. Therefore, the fixed effects method was used to combine the data and perform meta-analysis. RESULT: The results of the meta-analysis showed that based on the fixed effect method, depression was associated with decreased breastfeeding self-efficacy on the first day (SMD = 0.62, 95%CI: -0.830, -0.41, p = 0.0001) and on the third day (SMD = 0.84, 95% CI: -0.55,1.14, p = 0.0001). The Begg and Manzumdar test revealed no publication bias, with p = 0.317. CONCLUSION: Postpartum depression may be associated with a decrease in the mother's breastfeeding self-efficacy and placing mother in a condition to pay low attention to her maternal role. Therefore, healthcare providers should provide adequate support according to the needs of mothers and develop diagnostic and treatment protocols to improve the level of maternal health.

Lactation duration and development of type 2 diabetes and metabolic syndrome in postpartum women with recent gestational diabetes mellitus.

BACKGROUND: The World Health Organization and United Nations Children's Fund recommend exclusive breastfeeding (EBF) for the first six months of an infant's life. Although evidence suggests that maintaining breastfeeding has positive impacts on glucose and lipid metabolism in postpartum women with a history of gestational diabetes mellitus (GDM), no study has investigated whether such effects differ between breastfeeding intensities. This study aimed to evaluate the impact of maintaining breastfeeding on prediabetes, type 2 diabetes mellitus (T2DM), and metabolic syndrome (MetS) six months postpartum in women with GDM. This study also examined the potential variations in glucometabolic outcomes between EBF at six months and partial breastfeeding at six months. METHODS: This prospective cohort study included 130 women with recent GDM who experienced live births between 7 September 2020 and 31 January 2023 at a university hospital in Bangkok, Thailand. All the women were free of T2DM and MetS at baseline (six weeks postpartum). We followed up these women six months postpartum to assess their breastfeeding practices (EBF at six months, partial breastfeeding at six months, or not maintaining breastfeeding) and evaluate their progression to prediabetes, T2DM, and MetS. Maintaining breastfeeding was defined as breastfeeding for six months. EBF was determined using the "recall since birth" method. RESULTS: Of the 130 participants included, the rates of prediabetes, T2DM, and MetS six months postpartum were 33% (n = 43), 2% (n = 3), and 17% (n = 22), respectively. In the unadjusted model, maintaining breastfeeding was associated with a reduction in the risks of prediabetes and MetS but not T2DM. After adjusting for potential confounders, maintaining breastfeeding was a significant protective factor only for prediabetes. The adjusted risk ratios and 95% confidence intervals were 0.54 (0.29, 0.99) for prediabetes and 0.47 (0.19, 1.06) for MetS. When EBF at six months and partial breastfeeding at six months were separately analyzed, the risks of prediabetes and MetS differed between the two groups. In the EBF at six months-to-partial breastfeeding at six months comparison, the adjusted risk ratios (95% confidence intervals) of prediabetes and MetS were 0.46 (0.22, 0.97) vs. 0.79 (0.25, 2.49) and 0.34 (0.11, 0.99) vs. 0.69 (0.22, 2.07), respectively. CONCLUSIONS: Maintaining breastfeeding reduced the risk of prediabetes and MetS, but not of T2DM, six months postpartum; these effects were significant only with EBF. These findings indicate that supporting maternal efforts to practice EBF for six months may improve women's health after GDM.
