Barriers to Exclusive Breastfeeding Among Women With Gestational Diabetes Mellitus in the United States

Promoting breastfeeding in women with gestational diabetes mellitus in high-income settings: an integrative review

BACKGROUND

Breastfeeding provides many short- and long-term health benefits for mothers and their infants and is a particularly relevant strategy for women who experience Gestational Diabetes Mellitus (GDM) during pregnancy. However, breastfeeding rates are generally lower amongst this group of women than the general population. This review's objective is to identify the factors that influence breastfeeding by exploring the experiences and outcomes of women in in high-income health care contexts when there is a history of GDM in the corresponding pregnancy.

METHODS

A comprehensive search strategy explored the electronic databases Medline, CINAHL, Web of Science and Scopus for primary studies exploring breastfeeding practices for papers published between January 2011 and June 2023. All papers were screened independently by two researchers with included papers assessed using the Crowe Critical Appraisal tool. Findings were analysed using a narrative synthesis framework.

RESULTS

From an initial search result of 1037 papers, 16 papers representing five high-income nations were included in this review for analysis - the United States of America (n = 10), Australia (n = 3), Finland (n = 1), Norway (n = 1), and Israel (n = 1). Fifteen papers used a quantitative design, and one used a qualitative design. The total number of participants represented in the papers is 963,718 of which 812,052 had GDM and 151,666 did not. Women with an immediate history of GDM were as likely to initiate breastfeeding as those without it. However, they were more likely to have the first feed delayed, be offered supplementation, experience delayed lactogenesis II and or a perception of low supply. Women were less likely to exclusively breastfeed and more likely to completely wean earlier than the general population. Maternity care practices, maternal factors, family influences, and determinants of health were contextual and acted as either a facilitator or barrier for this group.

CONCLUSION

Breastfeeding education and support need to be tailored to recognise the individual needs and challenges of women with a history of GDM. Interventions, including the introduction of commercial milk formula (CMF) may have an even greater impact and needs to be very carefully considered. Supportive strategies should encompass the immediate and extended family who are major sources of influence.

Self-management of type 2 diabetes mellitus in pregnancy and breastfeeding experiences among women in Thailand: Study protocol

Women with type 2 diabetes mellitus are at a higher risk of pregnancy complications. Although traditional beliefs and practices influence diabetes management and breastfeeding, recommendations integrating Thai cultural beliefs in maternal care are lacking. The purpose of this study is to describe diabetes self-management in pregnancy and breastfeeding experiences in women with preexisting type 2 diabetes mellitus from Thailand. A convergent parallel mixed-methods study will be conducted. Data will be collected from 20 pregnant women with preexisting type 2 diabetes mellitus in Thailand who are either primigravida or multigravida, aged 20-44 years old, speak the Thai language, and provide consent. The National Institute on Minority Health and Health Disparities Framework's sociocultural and behavioral domains guides the research aims. Data will be collected two times. The first time is during pregnancy (T1); study participants will complete questionnaires and engage in an interview about diabetes self-management, breastfeeding confidence, and breastfeeding intention. The second time is at 4-6 weeks postpartum (T2); study participants will be interviewed about their breastfeeding experiences. We will review and extract maternal health outcomes including body mass index, gestational weight gain, and glycated hemoglobin for T1 as well as fasting plasma glucose for T2. Qualitative data will be analyzed using directed content analysis. Quantitative data will be analyzed using descriptive statistics. Data sources will be triangulated with relative convergence in the results. This proposed study is significant because the findings will be used as a preliminary guide to developing a culturally tailored approach to enhance health outcomes of Thai women with diabetes in pregnancy and postpartum periods.

Decision-making process of breastfeeding behavior in mothers with gestational diabetes mellitus based on health belief model

BACKGROUND

Gestational diabetes mellitus (GDM) threatens GDM mothers and their offspring's health and breastfeeding is one of the most effective ways to decrease the risk. However, the prevalence of breastfeeding among GDM mothers is far from optimal and how GDM mothers develop their feeding behavior is still unclear. Thus, this study aimed to explore the formation of GDM mothers' breastfeeding behaviors based on the health belief model (HBM).

METHODS

A questionnaire survey was conducted on 324 GDM mothers who have given birth within 6 months from January 1 to February 6, 2022. According to HBM, GDM mothers' knowledge, the perceived threat from GDM, the perceived value of breastfeeding, self-efficacy, social support and GDM mothers' breastfeeding behavior were measured. Exclusive breastfeeding (EBF) was defined as an infant who received only breast milk in the past 24 h before the survey. Structural equation modeling (SEM) was applied to explore how GDM mothers form their breastfeeding behaviors based on HBM.

RESULTS

The prevalence of EBF among GDM mothers was 33.95%. GDM mothers had limited knowledge of GDM (average 63.14% correct answer to 7 questions), especially poor on the long-term effect of GDM (39.81%) and protective effect of breastfeeding (34.57%-45.99%). Although GDM mothers showed high perceived benefits (Mean: 3.35, SD: 0.46), high self-efficacy (Mean: 3.43, SD: 0.97) and high level of social support for breastfeeding (Mean: 3.74, SD: 0.74), the various barriers (Mean: 2.20, SD: 0.47) hindered their success in EBF. The SEM results showed that a higher level of social support and more self-efficacy of breastfeeding resulted in a higher likelihood of EBF, while the higher level of knowledge of GDM, perceived higher barriers and benefits of breastfeeding and higher susceptibility to GDM consequences led to less EBF.

CONCLUSION

To promote EBF, physicians' education, emphasizing the protective effect of breastfeeding and how to correct breastfeeding, is highly recommended. In addition, social support for GDM mothers is also important to reduce their barriers to breastfeeding and help enhance self-efficacy in breastfeeding.

Predictors of Prenatal Breastfeeding Self-Efficacy in Expectant Mothers with Gestational Diabetes Mellitus

Breastfeeding is beneficial for mothers with gestational diabetes mellitus (GDM). Saudi Arabia is considered one of the countries with the highest prevalence of GDM. Mothers with GDM have a low intention to breastfeed and are less likely to continue breastfeeding. This study aimed to measure breastfeeding self-efficacy among expectant mothers with GDM and quantify its determinants. This cross-sectional study recruited expectant mothers with GDM from an antenatal care clinic and queried them on breastfeeding knowledge and attitudes using the Arabic validated prenatal breastfeeding self-efficacy scale (PBSES). The study took place at the Medical City of King Saud University, during January–April 2021. The average PBSES score among 145 GDM Saudi participants was 64.07 ± 16.3. Higher academic level, previous satisfactory breastfeeding experiences, breastfeeding intention, six months or more breastfeeding experience, and health education were significantly positively correlated with PBSES score. A higher knowledge score was also correlated with a higher PBSES score (p = 0.002). Longer breastfeeding duration (β.197, p = 0.036), satisfactory previous breastfeeding experience (β.218, p = 0.020), and higher knowledge score (β.259, p = 0.004) were significant predictors of a high PBSES score. Breastfeeding self-efficacy is low among expectant Saudi mothers with GDM, especially those with unsatisfactory previous experience or low knowledge scores. Establishing systematic education about breastfeeding during antenatal care is recommended to improve breastfeeding experience and improve GDM outcomes.

Lactation Consultation by an International Board Certified Lactation Consultant Improves Breastfeeding Rates for Mothers With Gestational Diabetes Mellitus

BACKGROUND

In patients with gestational diabetes, breastfeeding decreases the lifetime risk of Type 2 diabetes by half. Lactation consultation has been shown to increase breastfeeding rates in the general population but has not been assessed in a gestational diabetes population.

RESEARCH AIMS

To determine if (1) a postpartum International Board Certified Lactation Consultant (IBCLC) consultation during delivery hospitalization improved inclusive (any) or exclusive breastfeeding rates at hospital discharge and 3 months postpartum in participants with GDM; and if (2) obstetrical providers' acknowledgement of maternal feeding preference affected the rates of IBCLC consultation for patients.

METHODS

This was a retrospective, comparative, secondary analysis of a prospective cohort (N = 517) study of women gestational diabetes. Participants who received a IBCLC consultation (n = 386; 74.5%) were compared to those who did not (n = 131; 25.5%). Baseline demographics, antepartum characteristics, neonatal information, mode of infant feeding at hospital discharge and 3 months postpartum, and IBCLC consultation during postpartum hospitalization were measured.

RESULTS

After adjusting for baseline differences, participants who received an IBCLC consultation were more likely to report any breastfeeding at postpartum discharge (aOR 4.87; 95% CI [2.67, 8.86]) and at 3 months postpartum (aOR 5.39; 95% CI [2.61, 11.16]) compared to participants who did not. However, there was no difference in exclusive breastfeeding rates between those who did and did not receive IBCLC consultation.

CONCLUSION

Inpatient IBCLC consultation during the immediate postpartum period was associated with improved rates of any breastfeeding in participants with GDM.

How breastfeeding behavior develops in women with gestational diabetes mellitus: A qualitative study based on health belief model in China

BACKGROUND

Gestational diabetes mellitus (GDM) is a condition in which women develop hyperglycemia during pregnancy, and is associated with long-term health burden on both mother and their offspring, such as future type 2 diabetes mellitus (T2DM). Although breastfeeding was expected to mitigate metabolic sequelae for both mothers and their newborns, the prevalence of breastfeeding in GDM mothers are sub-optimal worldwide.

OBJECTIVE

To explore the experience of disease among mothers with GDM and how they develop feeding behaviors.

METHODS

This study was conducted in three branches of an integrated tertiary hospital in the central area of China. Mothers who were diagnosed with GDM, had no other complications, and gave birth before no more than 6 months were approached based on a purposive sampling. GDM mothers' experience of the disease and breastfeeding were collected via in-depth interviews. A theory-driven thematic analysis based on Health Belief Model (HBM) was applied for data analysis. Inductive reasoning was used to identify emerging themes which were not included in HBM.

RESULTS

16 GDM mothers were included in the current study, with nine using breastfeeding, six mixed feeding and one artificial feeding, respectively. Nine themes were identified, including: 1) GDM diagnosis and severity; 2) information searching and GDM knowledge;3) GDM management; 4) perceived susceptibility of future diabetes;5) perceived severity of future diabetes;6) perceived benefits of breastfeeding;7) perceived barriers of breastfeeding;8) decision making process of feeding and social support. Generally, mothers with GDM lack reliable sources of information, considered the disease as a minor and transient illness during pregnancy, and failed to realize the long-term risk of GDM and the protective effect of breastfeeding to themselves and their babies. They rarely considered GDM in their feeding decision. Instead, the formation of feeding behaviors depends on the balance between the benefits and barriers of breastfeeding as well as the level of social support.

CONCLUSION

To promote breastfeeding, a multi-facet intervention targeted on healthcare providers (HCPs), GDM mothers and their networks was important to help GDM mothers better and correctly understand the disease and breastfeeding, and increase their capacity of breastfeeding.

An exploration of differences in infant feeding practices among women with and without diabetes in pregnancy: A mixed-methods study

AIMS

(1) To determine the likelihood of full breastfeeding at 3 months postpartum in women with and without diabetes in pregnancy (DiP); (2) to explore the associations between diabetes management practices and infant feeding practices in those who had DiP and (3) to examine women's experiences of feeding their infants after having DiP.

METHODS

The quantitative study used data from Alberta Pregnancy Outcomes and Nutrition (APrON) cohort study. Participants who had DiP (n = 62) were matched 1:3 to participants without DiP for pre-pregnancy BMI, parity, mode of delivery and pre-term birth. Infant feeding questionnaires, prospective breastfeeding diaries and medical chart data were analysed to determine likelihood of fully breastfeeding at 3 months postpartum. For the qualitative study, interviews were conducted with postpartum women who had DiP to explore the experiences of infant feeding. Interviews were thematically analysed, and the results were compared between women who were categorized as 'full breast feeders' or 'mixed feeders'.

RESULTS

The odds of fully breastfeeding were 50% lower in women with DiP than women without DiP (OR: 0.50, 95% CI 0.25-0.99, p = 0.04). Qualitative interviews identified that although all women showed resilience in the face of infant feeding challenges, those who were fully breastfeeding reported seeking out external infant feeding supports, for example, classes or Doula's. Mixed Feeders perceived there was a lack of infant feeding information and support given to them prior to giving birth.

CONCLUSION

Women with DiP may require additional prenatal and postnatal infant feeding support to be better prepared to overcome feeding challenges they may face.

Breastfeeding support and barriers to women with gestational diabetes mellitus: a nationwide cross-sectional survey of hospitals in Japan

BACKGROUND

Despite the benefits of breastfeeding for women with Gestational Diabetes Mellitus (GDM) and their infants, breastfeeding is less likely to be performed by this group. This study aimed to examine the current levels of implementation of breastfeeding support to women with GDM in Japan and to clarify barriers to promoting breastfeeding among this population.

METHODS

A 25-item questionnaire was developed by the authors to investigate the current levels of implementation of breastfeeding support for women with GDM provided in hospitals, and to explore barriers for promoting breastfeeding among these women. The questionnaire was sent to all 1046 hospitals facilitating childbirth in Japan. Descriptive statistics were used to analyze the quantitative data, and content analysis was used to analyze qualitative data from the open-ended questions.

RESULTS

All 296 respondents were included in this study. Regarding breastfeeding support, 95.2% of the respondents provided general information on breastfeeding to GDM women during antenatal midwife consultations. However, the benefits of breastfeeding for preventing type 2 diabetes were addressed by only 48.0%. Likewise, although follow-up services (e.g., telephone support or breastfeeding consultations) were conducted in 88.9% of hospitals, only 50.7% of hospitals informed women that breastfeeding decreases the risk of developing type 2 diabetes after GDM. Regarding barriers, seven categories and 20 subcategories about promoting breastfeeding for women with GDM were extracted and abstracted into the following three themes: Barriers associated with mother and infant, Barriers associated with health professionals, and Organizational barriers.

CONCLUSIONS

In Japan, most hospitals that responded provided general breastfeeding support from the antenatal to postpartum periods. However, the benefits of breastfeeding in terms of preventing the incidence of type 2 diabetes following GDM were insufficiently communicated to women with GDM. Furthermore, there were numerous barriers to promoting breastfeeding among women with GDM.

Screening for Gestational Diabetes: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

IMPORTANCE

Gestational diabetes is associated with several poor health outcomes.

OBJECTIVE

To update the 2012 review on screening for gestational diabetes to inform the US Preventive Services Task Force.

DATA SOURCES

MEDLINE, EMBASE, and CINAHL (2010 to May 2020), ClinicalTrials.gov, reference lists; surveillance through June 2021.

STUDY SELECTION

English-language intervention studies for screening and treatment; observational studies on screening; prospective studies on screening test accuracy.

DATA EXTRACTION AND SYNTHESIS

Dual review of titles/abstracts, full-text articles, and study quality. Single-reviewer data abstraction with verification. Random-effects meta-analysis or bivariate analysis (accuracy).

MAIN OUTCOMES AND MEASURES

Pregnancy, fetal/neonatal, and long-term health outcomes; harms of screening; accuracy.

RESULTS

A total of 76 studies were included (18 randomized clinical trials [RCTs] [n = 31 241], 2 nonrandomized intervention studies [n = 190], 56 observational studies [n = 261 678]). Direct evidence on benefits of screening vs no screening was limited to 4 observational studies with inconsistent findings and methodological limitations. Screening was not significantly associated with serious or long-term harm. In 5 RCTs (n = 25 772), 1-step (International Association of Diabetes and Pregnancy Study Group) vs 2-step (Carpenter and Coustan) screening was significantly associated with increased likelihood of gestational diabetes (11.5% vs 4.9%) but no improved health outcomes. At or after 24 weeks of gestation, oral glucose challenge tests with 140- and 135-mg/dL cutoffs had sensitivities of 82% and 93%, respectively, and specificities of 82% and 79%, respectively, against Carpenter and Coustan criteria, and a test with a 140-mg/dL cutoff had sensitivity of 85% and specificity of 81% against the National Diabetes Group Data criteria. Fasting plasma glucose tests with cutoffs of 85 and 90 mg/dL had sensitivities of 88% and 81% and specificities of 73% and 82%, respectively, against Carpenter and Coustan criteria. Based on 8 RCTs and 1 nonrandomized study (n = 3982), treatment was significantly associated with decreased risk of primary cesarean deliveries (relative risk [RR], 0.70 [95% CI, 0.54-0.91]; absolute risk difference [ARD], 5.3%), shoulder dystocia (RR, 0.42 [95% CI, 0.23-0.77]; ARD, 1.3%), macrosomia (RR, 0.53 [95% CI, 0.41-0.68]; ARD, 8.9%), large for gestational age (RR, 0.56 [95% CI, 0.47-0.66]; ARD, 8.4%), birth injuries (odds ratio, 0.33 [95% CI, 0.11-0.99]; ARD, 0.2%), and neonatal intensive care unit admissions (RR, 0.73 [95% CI, 0.53-0.99]; ARD, 2.0%). The association with reduction in preterm deliveries was not significant (RR, 0.75 [95% CI, 0.56-1.01]).

CONCLUSIONS AND RELEVANCE

Direct evidence on screening vs no screening remains limited. One- vs 2-step screening was not significantly associated with improved health outcomes. At or after 24 weeks of gestation, treatment of gestational diabetes was significantly associated with improved health outcomes.

Determinants of Successful Exclusive Breastfeeding for Saudi Mothers: Social Acceptance Is a Unique Predictor

Recent guidelines motivate health care professionals to promote exclusive breastfeeding (EBF). The reported rate of EBF is low in Saudi Arabia. This study aimed to explore the determinants of successful exclusive breastfeeding for Saudi mothers. A cross-sectional, survey-based study was conducted in family medicine clinics. The dependent variable was the actual practice of EBF. Independent variables were the mothers’ demographic information, comfortableness with breastfeeding in public, knowledge and attitudes about breastfeeding, previous experience of successful breastfeeding, and a previous feeding plan. Statistical analysis was carried out using bivariate analysis and multinomial logistic regression. Out of the 322 respondents, only 28% practiced exclusive breastfeeding for the first six months. Perceived insufficient milk (p = 0.011) was associated with a lower EBF rate. Mothers’ degrees of comfort with breastfeeding in front of their relatives (p = 0.024) and in front of friends (p = 0.028) were significantly associated with their infants’ actual feeding practices for the first six months of their infants’ lives. Mothers reported that the absence of a suitable place for breastfeeding caused them to stop breastfeeding (p = 0.043) and was associated with their infant’s actual feeding practices for the first six months of their infant’s lives. An antenatal breastfeeding intention was considered a significant predictor of EBF; OR: 7.31 (95% CI: 2.24—23.84). Mothers who do not stop breastfeeding when they get sick have a 5.054 times higher chance of continuing EBF (95% CI: 1.037—24.627) than the formula-only feeding group. Thus, social acceptance is a unique predictor for their success in exclusive breastfeeding. Mothers have good intentions and a desire to breastfeed. Therefore, they must be guided through their pregnancy and postpartum period to overcome breastfeeding issues.

Breastfeeding Success Among Women with Gestational Diabetes Managed by Diet Only Compared with Those Requiring Medications

Objective: Breastfeeding is known to have a positive impact on maternal and neonatal health. Some have suggested that gestational diabetes mellitus (GDM) is associated with lower breastfeeding rates, but it is not known whether rates are further impacted by glucose control in pregnancy. Thus, we examined whether patients with GDM requiring medication (A2 GDM) were more likely to not initiate or discontinue breastfeeding compared with patients with GDM well controlled by diet (A1 GDM). Research Design and Methods: This is a secondary analysis of a prospective cohort study of 600 patients with GDM. Eligible patients were enrolled during their delivery hospitalization and followed prospectively postpartum. The primary outcome was exclusive breastfeeding at hospital discharge and secondary outcomes included breastfeeding rates at 3 months postpartum. Patients classified as A2 GDM were compared with those classified as A1 GDM. Results: Of the 600 patients enrolled, 301 had A2 GDM and 299 had A1 GDM. Patients who needed medication were observed to be older and more likely to be parous and obese. There were no significant differences in labor outcomes or neonatal complications. After adjusting for baseline differences between the two groups, adjusted odds ratios (aORs) for exclusive breastfeeding rates were similar in mothers with A2 GDM compared with those with A1 GDM at hospital discharge (aOR 0.83 [0.54-1.28]) and 3 months postpartum (aOR 0.58 [0.34-1.01]). Additionally, any breastfeeding rates were similar in mothers with A2 GDM compared with those with A1 GDM, both at hospital discharge (aOR 0.72 [0.44-1.16]) and 3 months postpartum (aOR 0.63 [0.34-1.17]). Conclusions: After adjusting for baseline differences, there was no difference in any or exclusive breastfeeding rates at hospital discharge or 3 months postpartum among patients with A2 GDM compared with those with A1 GDM.

Factors that positively influence in-hospital exclusive breastfeeding among women with gestational diabetes: An integrative review

PROBLEM

Women with gestational diabetes have higher rates of introducing infant formula before leaving hospital.

BACKGROUND

Despite health professional support, less women with gestational diabetes exclusively breastfeed in hospital.

AIM

To find factors that positively influence in-hospital exclusive breastfeeding practices among women with gestational diabetes.

METHODS

An online search was performed in Medline, Scopus, Pubmed, CINAHL and Cochrane databases. Studies containing the keywords gestational diabetes and breastfeeding were retrieved.

FINDINGS

Authors identified 1935 papers from search criteria. Twenty-six papers with no restrictions on research design met inclusion criteria and were included in the review. Factors were divided into personal, antenatal, intrapartum and postnatal factors. The main modifiable factors that were associated with improved in-hospital exclusive breastfeeding rates were having a strong intention to breastfeed, being confident, feeling supported and having continuity of education and support. Women's main reasons to introduce formula were related to baby's hypoglycaemia, delayed lactogenesis II and perceived low milk supply. Skin-to-skin contact after birth combined with frequent breastfeeds were effective ways to improve in-hospital exclusive breastfeeding rates.

CONCLUSION

Influencing factors such as women's breastfeeding intention, confidence and ongoing support are no different to the general population of women. However, promoting skin-to-skin contact after birth combined with frequent feeds are crucial for women with gestational diabetes who are more likely to introduce formula due to delayed lactogenesis II and fear of neonatal hypoglycaemia. There is a need for developing educational and supportive interventions that are tailored specifically for women who have gestational diabetes.

Barriers and benefits to breastfeeding with gestational diabetes

Gestational diabetes mellitus (GDM) is a disease of glucose intolerance during pregnancy and is associated with infant macrosomia, infant hypoglycemia, and increased risk of type 2 diabetes development for both mother and infant. Although breastfeeding potentially mitigates metabolic sequelae for both mother and her offspring, women with GDM are more likely to introduce formula and, therefore, are less likely to exclusively breastfeed, and some studies show less initiation and shorter breastfeeding duration as well. Therefore, women with GDM and their infants warrant investigation of methods by which to increase breastfeeding exclusivity and duration. Exploration of the barriers to breastfeeding for women with GDM demonstrate not only biologic complications such as maternal obesity, increased prevalence of cesarean section, and infant hypoglycemia, but also maternal report of less provider support of breastfeeding and reduced breastfeeding self-efficacy. Consequently, interventions designed to optimize breastfeeding outcomes in this high-risk population should not only focus on the biology but also on provider behavior and maternal social factors.

Knowledge and Health Beliefs of Gestational Diabetes Mellitus Associated with Breastfeeding Intention Among Pregnant Women in Bangladesh

PURPOSE

This study aimed to investigate the knowledge of gestational diabetes mellitus (GDM) and the health beliefs about GDM management, as well as to investigate the effects of these factors on breastfeeding intention in Bangladesh.

METHODS

This study involved a cross-sectional survey of 358 healthy pregnant women who visited antenatal clinics in Bangladesh.

RESULTS

Perceived susceptibility, perceived benefit, and self-efficacy were identified as significant factors for breastfeeding intention (p < .05). Participants had a poor understanding and a lack of knowledge of GDM, which can lead to inadequate health behavior. Health beliefs were significantly associated with participants' breastfeeding intention related to GDM.

CONCLUSION

Antenatal education for breastfeeding in GDM mothers should focus on providing accurate information on GDM and strengthening their health beliefs such as self-efficacy within the context of the mothers' culture.

Breastfeeding Initiation as Related to the Interaction of Race/Ethnicity and Maternal Diabetes

Introduction: The health benefits of breastfeeding for both the mother and her offspring are well established, and breastfeeding may be especially important for mitigating negative health effects of pregnancy complicated by diabetes. Objective: This study sought to examine the association between race/ethnicity, maternal diabetes, and breastfeeding initiation in South Carolina (SC). Materials and Methods: Our study population is comprised of all live, singleton, full-term births in SC delivered January 2004 to December 2016 (292,468 non-Hispanic Whites, 173,158 non-Hispanic Blacks, and 52,174 Hispanics). Generalized estimating equations and an interaction term between race/ethnicity and maternal diabetes status were used to estimate the race/ethnic-specific odds ratio (OR) and 95% confidence intervals (CIs) that a mother with diabetes versus without diabetes initiated breastfeeding. Models were adjusted for maternal and infant sociodemographics (Model 1), additionally for clinical variables and birth outcomes (Model 2), and also for maternal prepregnancy body mass index (BMI) (Model 3). Results: We found statistically significant differences in breastfeeding initiation by race/ethnicity and diabetes status in Model 1. These associations were attenuated and lost significance upon additional adjustment. Non-Hispanic Black mothers with gestational diabetes were significantly more likely to initiate breastfeeding than nondiabetic non-Hispanic Black mothers, even after adjustment for prepregnancy BMI (OR: 1.07 [95% CI 1.02-1.12]). Conclusion: This large, population-based study of all live, singleton, full-term births in SC improves our understanding of how race/ethnicity and maternal metabolic disorders impact breastfeeding initiation, and may inform future hospital-based breastfeeding interventions in populations with the most need.

Caesarean delivery associated with adverse breastfeeding practices: a prospective cohort study

Caesarean delivery rates are increasing in many Asian countries. This study investigated the effects of caesarean section on breastfeeding practices from delivery to twelve months postpartum. A prospective cohort study was conducted on 2030 pregnant women recruited from three cities in Vietnam during 2015-2017. The overall caesarean rate was 38.1%. Mothers who underwent caesarean section were more likely to give prelacteal feeds to their infants (adjusted odds ratio (OR) 13.91, 95% confidence interval (CI) 10.52-18.39) and as a result have lower rates of early initiation of breastfeeding (adjusted OR 0.04, 95%CI 0.02-0.05). Having a caesarean section reduced the likelihood of (any, predominant and exclusive) breastfeeding from discharge to 6 months postpartum. After 1 year, the any breastfeeding rate was still lower in the caesarean delivery (70.2%) compared with the vaginal delivery group (72.9%), p = .232. Vietnamese women who give birth by caesarean section need extra support to initiate and maintain breastfeeding.IMPACT STATEMENTWhat is already known on this subject? Early initiation of breastfeeding, and 'exclusive' or 'predominant' breastfeeding rates at discharge are lower in mothers delivering by caesarean section compared to vaginal delivery. Prelacteal feeding rates are higher following caesarean section. However, the association between 'any' breastfeeding duration and caesarean delivery has not been established.What the results of this study add? This study showed that caesarean delivery reduced all breastfeeding rates from discharge to six months and any breastfeeding rate at 12 months postpartum in Vietnamese women.What the implications are of these findings for clinical practice and/or further research? Further breastfeeding interventions are needed during the postpartum period for mothers who deliver by caesarean section.

Gestational Diabetes Mellitus Reduces Breastfeeding Duration: A Prospective Cohort Study

BACKGROUND

Gestational diabetes mellitus (GDM) and its complications are major concerns because of the negative effects of GDM during antenatal period and on the future health of mothers and infants. Breastfeeding is beneficial for GDM mothers and their babies to reduce future health risks. Little is known about the link between GDM and the duration of "any" breastfeeding. Therefore, the aim of this study was to investigate the relationship between GDM and the duration for which Vietnamese women breastfeed their babies postpartum.

MATERIALS AND METHODS

A prospective cohort of 2,030 pregnant women between 24 and 28 weeks of gestation was recruited. GDM status was determined using a 75 g oral glucose tolerance test. Included mothers were then followed up from discharge after childbirth until 12 months postpartum to determine their breastfeeding duration. Kaplan-Meier estimates, log-rank tests, logistic and Cox regression models were used to examine the association between GDM and breastfeeding outcomes.

RESULTS

In our cohort, 94.4% of all women reported "any" breastfeeding at discharge and 72.9% of women were still breastfeeding at 12 months postpartum. The risk of early breastfeeding cessation was higher in GDM women than their non-GDM counterparts after adjustment for demographic factors (hazard ratios [HR] = 1.39, 95% confidence intervals [CI] = 1.13-1.71, p = 0.002), and all potential confounding factors (HR = 1.38, 95% CI = 1.12-1.70, p = 0.002). There were no significant differences in breastfeeding outcomes at discharge (early initiation, prelacteal feeding, and "any" breastfeeding rate) between GDM and non-GDM mothers.

CONCLUSIONS

GDM was associated with shorter breastfeeding duration. Women with GDM require ongoing support after hospital discharge to maintain long-term breastfeeding.
