Breastfeeding initiation: impact of obesity in a large Canadian perinatal cohort study

A perinatal social nutrition approach to improve breastfeeding in a culturally diverse group of low-income women

Alima, Perinatal Social Nutrition Centre, is an established community organization that adopts a perinatal social nutrition approach to provide multidimensional support to women living in vulnerable conditions, particularly those with a precarious migratory status. This study aims to (i) determine which maternal characteristics, pregnancy-related variables, and structural features of the Alima intervention are associated with breastfeeding; and (ii) examine whether the association between attending breastfeeding workshops and breastfeeding characteristics differ according to maternal factors. The Alima digital database was used to analyze data from women who received the perinatal intervention between 2013 and 2020. Infant feeding data were retrieved at 2 weeks postpartum (T0, n = 2925), 2 months postpartum (T2, n = 1475), and 4 months postpartum (T4, n = 890). Logistic regressions were used to estimate the odds of overall and exclusive breastfeeding depending on sociodemographic characteristics, pregnancy-related variables, and features of the intervention. The prevalence of overall and exclusive breastfeeding was, respectively, 96.1% and 60.7% at T0; 93.0% and 58.5% at T2; 83.0% and 48.4% at T4. Higher education, previous breastfeeding experience, and recent immigration were associated with a higher likelihood of breastfeeding at each time point. Breastfeeding workshop attendance was associated with a greater likelihood of overall and exclusive breastfeeding at T2 and T4, with a stronger effect among women aged 35 or less, those with lower education, and those with excessive gestational weight gain. In conclusion, the Alima intervention is associated with positive breastfeeding outcomes, especially among vulnerable women living with precarious migratory status in Canada.

The Impact of Excessive Weight on Breastfeeding Intention, Initiation, and Duration

Background: Breastfeeding is widely recognized as the optimal feeding method for infants. However, breastfeeding goals are often unmet, especially in mothers with excessive weight. Potential factors associated with unmet goals could be disparities in care for women with higher body mass index (BMI) or mental health symptomology. Methods: Women enrolled in a longitudinal study were stratified by BMI into three groups: mothers with normal weight (18.5-24.9 kg/m2, n = 101), with overweight (25-29.9 kg/m2, n = 78), and with obesity (OB; 30-35 kg/m2, n = 48). Breastfeeding intention and standardized mental health questionnaires were administered at gestational weeks 12 and 36. The prevalence of initiation and duration of breastfeeding were determined based on self-reported breastfeeding start and end dates. Wilcoxon tests, pairwise proportion test, Cox proportional hazards regression, and linear regression were used. Results: Higher maternal weight status (OB) was significantly associated with lower breastfeeding intention and duration. As expected, higher breastfeeding intention scores were associated with significantly longer breastfeeding duration. Higher scores on the Beck Depression Inventory (BDI), associated with a greater number of depression symptoms, mediated the negative impact of weight status on breastfeeding intention. Conclusions: breastfeeding outcomes are negatively associated with maternal weight status and prenatal mental health with the relationship between the two being interconnected, despite subclinical scores on the BDI. Further research is needed to explore the role of mental health on breastfeeding outcomes. From these findings, targeted prenatal interventions for women with excessive weight and depressive symptoms would likely promote and improve breastfeeding outcomes.

Main Biopsychosocial Factors Influencing Breastfeeding: a Systematic Review

Background: Background: Breastfeeding is important for an infant's development as well as the mother's recovery after birth. Breastfeeding is influenced by a variety of biopsychosocial variables. The purpose of this study was to conduct a comprehensive literature search and explore the relationship between any biopsychological component and breastfeeding duration and intensity. Methods:The databases of PubMed and ScienceDirect were searched. The official website of World Health Organization (WHO) was also explored. Results:The search identified 19 studies, reporting the main biopsychosocial factors affecting breastfeeding intention and duration, including maternal age, occupation, smoking, obesity, the feeding type that the women received, social support, birth complications, cesarean delivery, anxiety and self-efficacy. Conclusion:This systematic review has confirmed that there are specific biopsychosocial factors influencing the breastfeeding process. It is proposed that current care and support should encourage mothers to breastfeed their newborns by providing corrective information and aid.

Influence of maternal excess weight before pregnancy on breast-feeding and weaning: pooled analyses of four population-based cohorts born between 1982 and 2015

To investigate the associations of maternal excess weight before pregnancy with (1) weaning at 3 months of age, (2) duration of exclusive breast-feeding at 6 months of age, (3) duration of any breast-feeding at 12 months of age and (4) to compare the magnitude of these associations over four decades. Data were from participants in the Pelotas (Brazil) Birth Cohorts born in 1982 (n 5334), 1993 (n 1442), 2004 (n 4092) and 2015 (n 4102). Maternal pre-pregnancy weight was collected after the delivery and breast-feeding status was assessed when children were 3 and 12 months old. Only in the most recent cohort (2015), women with excess weight (BMI ≥ 25 kg/m²) before pregnancy had higher risk of discontinuing exclusive breast-feeding within the first 6 months postpartum than women with normal weight (hazard ratio = 1·22 (95 % CI 1·15, 1·30)). Duration of any type of breast-feeding until 12 months of age was not affected by pre-pregnancy weight. Excess weight before pregnancy is associated with exclusive breast-feeding only in the most recent birth cohort coinciding with increases in excess weight and breast-feeding over time.

BMI and miscarriage after IVF

PURPOSE OF REVIEW

To summarize recent findings related to the risk of miscarriage in women with elevated BMI undergoing IVF, and the mechanisms involved in said risk.

RECENT FINDINGS

Miscarriage rates are increased in overweight and obese women in both natural and assisted reproduction. Oocyte and embryo quality assessed according to classic morphological static parameters does not seem to be affected by excessive female body weight. Despite the initial lack of consensus between studies regarding embryo morphokinetics in obese women, blastocyst formation and quality have recently been shown to be similar across BMI groups, even in the case of euploid embryos. However, some metabolomic differences have been described in oocytes and embryos from obese women, thus pointing to a functional alteration. In women with elevated BMI, the percentage of aneuploid embryos is similar to that of normal weight women, and rates of miscarriage are higher, despite the transfer of euploid embryos. Therefore, the origin of the increased pregnancy loss rate after IVF in these women may be related to metabolomic, epigenetic or mitochondrial oocyte and embryo disturbances, or to the abnormal endocrine, metabolic and inflammatory uterine environment induced by obesity, which seems to be also responsible for other numerous complications during pregnancy and the in-utero fetal programming of postnatal diseases. A displacement of the window of implantation in obese women undergoing artificial endometrial preparation has recently been described and may be related to the poorer embryo implantation rates and increased risk of miscarriage observed following fresh and frozen embryo transfers with autologous oocytes, and with donated ova in recipients with extremely high BMI.

SUMMARY

Female obesity is related to poorer outcome in natural and assisted conception, including an increased risk of miscarriage. Embryo morphology, assessed by conventional methods or by morphokinetics, does not seem to be affected by excess weight, with similar blastocyst formation and quality than normal weight women reported in IVF cycles. Embryo aneuploidy is not increased, and higher miscarriages rates are seen after euploid embryo transfer in obese women. Disturbances of the uterus or its environment induced by female obesity seem to be the most likely cause of the increased risk of miscarriage, although metabolomic, epigenetic or mitochondrial oocyte and embryo dysfunction cannot be ruled out as cannot congenital anomalies. In the context of all the above, weight reduction before pregnancy should be advised in obese women trying to become pregnant.

Breastfeeding Practices in the United Arab Emirates: Prenatal Intentions and Postnatal Outcomes

Breastfeeding provides the ideal nutrition in infancy, and its benefits extend to the health of mothers. Psychosocial factors such as the intention to breastfeed, self-efficacy, or maternal confidence to breastfeed have been shown to impact breastfeeding outcomes in other communities. The aim of this study was to assess the potential associations between mothers’ prenatal intention to breastfeed and post-delivery breastfeeding practices. A cross-sectional study was conducted from March to September 2017. Emirati and non-Emirati mothers with children below the age of 2 were recruited from maternal and child health centers in various geographical areas in Abu Dhabi Capital district, United Arab Emirates. The variables (mothers’ intention to breastfeed, breastfeeding knowledge, support from family and health care professionals, and initiation and duration of breastfeeding) were collected by research assistants during an in-person interview, using a structured questionnaire. A total of 1799 mothers participated in this study. Mothers’ prenatal intention to breastfeed was significantly associated with breastfeeding initiation (p < 0.001) and length of exclusive breastfeeding (p = 0.006). Furthermore, intention to breastfeed during early pregnancy showed a strong association (p < 0.001) with mothers who had exclusively breast fed for more than three months. In addition, knowledge on the benefits of breastfeeding and getting support from relatives and non-relatives demonstrated significant relationship with a longer period of exclusive breastfeeding (p < 0.01) In total, mothers in the study reported receiving almost four thousand advice about breastfeeding, of which 3869 (97%) were encouraging to our others in the study. Our findings on prenatal intentions, knowledge and network support on exclusive breastfeeding indicates the importance of including breastfeeding knowledge and support as critical topics during prenatal education, not only to the mothers but also to close network members who seek a healthy pregnancy outcome.

The Role of Maternal Prepregnancy Body Mass Index in Breastfeeding Outcomes: A Systematic Review

Background: The benefits of breastfeeding are well established in the literature. Barriers related to breastfeeding, such as maternal obesity, are also cited in the literature. Worldwide obesity rates in women of reproductive age are rising at an alarming pace. Previous research has attempted to study the relationship between maternal body mass index (BMI) and its effect on breastfeeding outcomes, but it is not clear what the role of maternal BMI category has on breastfeeding outcomes. Objectives: The objective of this review is to examine whether and how maternal BMI affects maternal breastfeeding outcomes such as intention, initiation, duration, and exclusivity. Methods: A systemic literature search through PubMed and Cumulative Index to Nursing and Allied Health Literature was conducted between January and May 2020, by using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of 23 relevant articles were retrieved. Results: Of the 23 studies that assessed the relationship between maternal BMI and breastfeeding intention and other outcomes, only 4 found no differences in breastfeeding outcomes across BMI categories. Higher than normal maternal prepregnancy BMI has been found to be associated with poorer breastfeeding outcomes. Overweight and obese women are less likely to intend to breastfeed and initiate breastfeeding. They also have shorter breastfeeding durations and are less likely to exclusively breastfeed for any period compared with normal weight women. Conclusions: Breastfeeding rates across all BMI categories do not meet the recommended guidelines established by the World Health Organization and other public health agencies, and overweight and obese women have poorer breastfeeding outcomes. Overweight and obese women need additional support to initiate breastfeeding, and to breastfeed longer and exclusively. Targeted and well-designed interventions should be implemented early in the perinatal period to support this vulnerable population.

The Relationship Between Internalized Weight Stigma During Pregnancy and Breastfeeding: A Prospective Longitudinal Study

OBJECTIVE

This study aimed to examine the relationship between internalized weight stigma during pregnancy and breastfeeding outcomes at 1 month post partum among individuals with prepregnancy overweight or obesity. Secondarily, the study explored the temporal stability of internalized weight stigma from the third trimester to 1 month post partum via the Weight Bias Internalization Scale (WBIS).

METHODS

A total of 103 pregnant individuals with overweight or obesity were recruited for this study. Participants completed the WBIS during the third trimester and self-reported breastfeeding initiation, continuation, and exclusivity outcomes at 1 month post partum. A paired t test and binomial logistic regression were conducted with covariates hierarchically added to the model.

RESULTS

The average prepregnancy BMI was 33.53 (SD 7.17) kg/m² (range = 25.4-62), and average prenatal WBIS scores were 25.95 (SD 11.83). No difference was found in mean prenatal and postpartum scores (25.95 [SD 11.83]; 26.86 [SD 13.03], respectively; t₉₄ = -0.83, P = 0.41), evidencing temporal stability in WBIS scores from pre to post partum. Prenatal WBIS scores did not predict breastfeeding initiation, continuation, or exclusivity at 1 month post partum in either unadjusted or adjusted models.

CONCLUSIONS

Collectively, this sample displayed low weight bias internalization, which was not predictive of breastfeeding initiation, continuation, or exclusivity at 1 month post partum. Future research is needed to develop a pregnancy-specific weight stigma measure.

Relationship between obesity and lower rates of breast feeding initiation in regional Victoria, Australia: an 8-year retrospective panel study

OBJECTIVES

Using routinely collected hospital data, this study explored secular trends over time in breast feeding initiation in a large Australian sample. The association between obesity and not breast feeding was investigated utilising a generalised estimating equations logistic regression that adjusted for sociodemographics, antenatal, intrapartum and postpartum conditions, mode of delivery and infant's-related covariates.

DESIGN

Population-based retrospective panel.

SETTING

A regional hospital that serves 26% of Victoria's 6.5 million population in Australia.

PARTICIPANTS

All women experiencing live births between 2010 and 2017 were included. Women with missing body mass index (BMI) were excluded.

RESULTS

A total of 7491 women contributed to 10 234 live births. At baseline, 57.2% of the women were overweight or obese, with obesity increasing over 8 years by 12.8%, p=0.001. Although, breast feeding increased over time, observed in all socioeconomic status (SES) and BMI categories, the lowest proportions were consistently found among the obese and morbidly obese (78.9% vs 87.1% in non-obese mothers, p<0.001). In the multivariable analysis, risk of not breast feeding was associated with higher BMI, teenage motherhood, smoking, belonging to the lowest SES class, gravidity >4 and undergoing an assisted vaginal or caesarean delivery. Compared with women with a normal weight, the obese and morbidly obese were 66% (OR 1.66, 95% CI 1.40 to 1.96, p<0.001) to 2.6 times (OR 2.61, 95% CI 2.07 to 3.29, p<0.001) less likely to breast feed, respectively. The detected dose-response effect between higher BMI and lower breast feeding was not explained by any of the study covariates.

CONCLUSION

This study provides evidence of increasing breast feeding proportions in regional Victoria over the past decade. However, these proportions were lowest among the obese and morbidly obese and those coming from the most disadvantaged backgrounds suggesting the need for targeted interventions to support breast feeding among these groups. The psychosocial and physiological associations between obesity and breast feeding should further be investigated.

The Impact of Socio-Demographic Factors on Breastfeeding: Findings from the "Mamma & Bambino" Cohort

Background and objectives: The World Health Organization (WHO) recommends women (1) to initiate breastfeeding within one hour of birth; (2) to exclusively breastfeed for the first six months; and (3) to continue breastfeeding until two years of age. However, women do not always adhere to these recommendations, threatening the health of their children. The present study aims to evaluate breastfeeding status and the main maternal factors associated with exclusive breastfeeding for six months among women from the "Mamma & Bambino" study, a prospective cohort settled in Catania, Italy. Materials and Methods: We used data from 220 women (median age = 37 years) enrolled in the "Mamma & Bambino" cohort during prenatal obstetric counselling. Self-reported breastfeeding status was collected during the follow-up interviews at 1 and 2 years, referring to breastfeeding status (i.e., yes or no) and type of breastfeeding (i.e., exclusive or predominant). We also collected data about duration of breastfeeding to classify women into those who adhered to the WHO recommendation and those who did not. Results: In the general population, we noted that the proportion of women who have breastfed increased with increasing educational level. Accordingly, logistic regression analysis demonstrated that medium (OR = 3.171; 95% CI = 1.285-7.822; p = 0.012) and high educational levels (OR = 4.549; 95% CI = 1.525-13.570; p = 0.007) were positively associated with breastfeeding if compared to low educational level. Among women who have breastfed, instead, the proportion of adherents to the WHO recommendation was higher among those with medium-high educational level and those who were employed. In line with this, we demonstrated that full-time employment (OR = 2.158; 95% CI = 1.033-4.508; p = 0.041) and medium educational level (OR = 4.632; 95% CI = 1.227-17.484; p = 0.024) were positively associated with exclusive breastfeeding for the first six months. Conclusions: Socio-demographic factors should be taken into account through public health strategies for improving maternal knowledge about health benefits of exclusive breastfeeding.

Obstetric and neonatal outcomes in women with pregnancy associated cancer: a population-based study in Lombardy, Northern Italy

BACKGROUND

Pregnancy associated cancer (PAC) may lead to adverse obstetric and neonatal outcomes. This study aims to assess the association between PACs and adverse perinatal outcomes [i.e. labor induction, iatrogenic delivery, preterm birth, small for gestational age (SGA) newborn, low Apgar score, major malformations, perinatal mortality] in Lombardy, Northern Italy.

METHODS

This population-based historic cohort study used the certificate of delivery assistance and the regional healthcare utilization databases of Lombardy Region to identify beneficiaries of National Health Service who delivered between 2008 and 2017. PACs were defined through oncological ICD-9-CM codes reported in the hospital discharge forms. Each woman with PAC was matched to four women randomly selected from those cancer-free (1:4). Log-binomial regression models were fitted to estimate crude and adjusted prevalence ratio (aPR) and the corresponding 95% confidence interval (CI) of each perinatal outcome among PAC and cancer-free women.

RESULTS

Out of the 657,968 deliveries, 831 PACs were identified (1.26 per 1000). PAC diagnosed during pregnancy was positively associated with labor induction or planned delivery (aPR=1.80, 95% CI: 1.57-2.07), cesarean section (aPR=1.78, 95% CI: 1.49-2.11) and premature birth (aPR=6.34, 95% CI: 4.59-8.75). No association with obstetric outcomes was found among PAC diagnosed in the post-pregnancy. No association of PAC, neither during pregnancy nor in post-pregnancy was found for SGA (aPR=0.71, 95% CI: 0.36-1.35 and aPR=1.04, 95% CI: 0.78-1.39, respectively), but newborn among PAC women had a lower birth weight (p-value< 0.001). Newborns of women with PAC diagnosed during pregnancy had a higher risk of borderline significance of a low Apgar score (aPR=2.65, 95% CI: 0.96-7.33) as compared to cancer-free women.

CONCLUSION

PAC, especially when diagnosed during pregnancy, is associated with iatrogenic preterm delivery, compromising some neonatal heath indicators.

Association between Adherence with Recommended Antenatal Care in Low-Risk, Uncomplicated Pregnancy, and Maternal and Neonatal Adverse Outcomes: Evidence from Italy

Antenatal care (ANC) aims of monitoring wellbeing of mother and foetus during pregnancy. We validate a set of indicators aimed of measuring the quality of ANC of women on low-risk, uncomplicated pregnancy through their relationship with maternal and neonatal outcomes. We conducted a population-based cohort study including 122,563 deliveries that occurred between 2015 and 2017 in the Lombardy Region, Italy. Promptness and appropriateness of number and timing of gynaecological visits, ultrasounds and laboratory tests were evaluated. We assessed several maternal and neonatal outcomes. Log-binomial regression models were used to estimate prevalence ratio (PR), and corresponding 95% confidence interval (95% CI), for the exposure→outcome association. Compared with women who adhered with recommendations, those who were no adherent had a significant higher prevalence of maternal intensive care units admission (PR: 3.1, 95%CI: 1.2-7.9; and 2.7, 1.1-7.0 respectively for promptness of gynaecological visits, and appropriateness of ultrasound examinations), low Apgar score (1.6, 1.1-1.2; 1.9, 1.3-2.7; and 2.1, 1.5-2.8 respectively for appropriateness and promptness of gynaecological visits, and appropriateness of ultrasound examinations), and low birth weight (1.8, 1.5-2.3 for appropriateness of laboratory test examinations). Benefits for mothers and newborn are expected from improving adherence to guidelines-driven recommendations regarding antenatal care even for low-risk, uncomplicated pregnancies.

Communication practices of healthcare professionals when caring for overweight/obese pregnant women: A scoping review

OBJECTIVE

To synthesize existing research on communication practices between healthcare professionals and overweight and obese pregnant women.

METHODS

Following PRISMA guidance on conducting scoping reviews, we included original research addressing communication/counseling practices of healthcare professionals with overweight and/or obese pregnant women, published between 2008-2018, and available in English. Fourteen articles are included in this review.

RESULTS

Study findings were organized into three themes: (a) topics addressed during encounters, (b) providers' comfort/confidence, knowledge and methods in communicating with overweight/obese pregnant women, and (c) overweight/obese pregnant women's experiences in communicating with healthcare providers. The most prevalent topics addressed were gestational weight gain, physical activity, and nutrition. Healthcare professionals experience discomfort and are reluctant to address weight status with overweight/obese pregnant patients, use vague statements about weight gain and weight-related obstetric risks, and report low confidence when counseling obese pregnant women. Overweight/obese pregnant women perceive weight stigma when interacting with providers.

CONCLUSION

Weight-related counseling in obstetric care is suboptimal. Providers may benefit from training to more confidently and effectively counsel overweight and obese pregnant women about gestational weight gain, physical activity, and nutrition.

PRACTICE IMPLICATIONS

Patients perceive weight stigma in the obstetric setting, which may be prevented by effective, patient-centered communication.

Effectiveness of a Pilot Breastfeeding Educational Intervention Targeting High BMI Pregnant Women

INTRODUCTION

Overweight and obesity during pregnancy are associated with adverse health outcomes leading to increased maternal and neonatal morbidity and mortality. Women with a high body mass index (BMI) also experience low breastfeeding rates. There is limited evidence of effective educational programs that aim to improve length of breastfeeding among this population. The main objective of this pilot educational intervention was to determine knowledge and skills retention at six weeks after completion of a breastfeeding class.

METHODS

A two-hour breastfeeding class was offered during the second and third trimester of pregnancy targeting high BMI women. A longitudinal, survey study design was conducted using two data collection points. No comparator group was employed.

RESULTS

Baseline mean age of respondents was 26.6 years (SD = 5.7). Respondents who completed post-intervention surveys were largely white (69.2%) followed by Hispanic (15.4%) and non-Hispanic black (15.4%), some college (57.1%), earned less than $50,000/year (64.3%), had employer-provided insurance (53.8%), and did not receive WIC benefits (78.6%). Most respondents had a pre-pregnancy BMI category of overweight (28.6%) or obese (57.1%). The intervention appeared to have some impact on responses. The following were observed: an increased understanding that baby may be fussy in the evening hours and wants to nurse more often (p < 0.002), how to bring baby to the breast (p = 0.004), knowing what to do if breastfeeding hurts (p = 0.031), and knowing what to do when baby has trouble breastfeeding (p = 0.021).

CONCLUSION

Consistent with previous findings, all participants in our study reported increased knowledge to breastfeed. Thus, women's confidence to breastfeed their infant is enhanced through knowledge obtained from breastfeeding education. Additional studies are underway to assess breastfeeding behaviors.

Maternal Body Mass Index and Breastfeeding Non-Initiation and Cessation: A Quantitative Review of the Literature

This study aims to investigate which maternal body mass index (BMI) categories are associated with the non-initiation or cessation of breastfeeding (BF) based on a quantitative review of the literature. We searched Ovid MEDLINE and EBSCO CINAHL for peer-reviewed articles published between 1946 (MEDLINE) or 1981 (CINAHL), and 2019. Selected studies were either cross-sectional or cohort studies, of healthy mothers and infants, that reported nutrition method (exclusive/full or any) and period (initiation/duration/cessation) of breastfeeding according to maternal BMI levels. Pairwise meta-analyses of 57 studies demonstrated that the pooled odds risks (OR) of not initiating BF among overweight and obese mothers compared to normal weight mothers were significant across 29 (OR 1.33, 95% confidence interval (CI), 1.15–1.54, I² = 98%) and 26 studies (OR 1.61, 95% CI, 1.33–1.95, I² = 99%), respectively; the pooled risks for BF cessation were inconsistent in overweight and obese mothers with substantial heterogeneity. However, we found that overweight mothers (n = 10, hazard ratio (HR) 1.16, 95% CI, 1.07–1.25; I² = 23%) and obese mothers (n = 7, HR 1.45, 95% CI: 1.27–1.65; I² = 44%) were both associated with an increased risk of not continuing any BF and exclusive BF, respectively. Overweight and obese mothers may be at increased risk of not initiating or the cessation of breastfeeding.

Maternal obesity adversely affects early breastfeeding in a multicultural, multi-socioeconomic Melbourne community

BACKGROUND

Maternal breastfeeding support and maternal obesity are concerns effectively addressed at the community level. International, national and regional surveys have established that elevated maternal body mass index (BMI) is a risk factor for early cessation of breastfeeding. However, the extent of these concerns in the local community is often an unknown and related to variables such as socioeconomic status, education, culture and ethnicity.

AIMS

We believed that a survey of post-natal breastfeeding and BMI status would provide a valuable insight into developing targeted local health initiatives.

MATERIALS AND METHODS

In 2014, we teamed up with the Whittlesea Maternal and Child Health Service to complete a questionnaire of mothers and babies attending the eight-week infant review. Data included: infant and maternal weight, medical conditions, breastfeeding experience and satisfaction, prime language, education level, support.

RESULTS

Maternal obesity at eight weeks postpartum was high at 28.9%, with 63.6% of mothers being overweight or obese. Obesity was associated with a lack of higher education (P < 0.05) and with English as the prime language (P < 0.05). Breastfeeding initiation was high across all BMI categories at 98.3%. By eight weeks, 32.2% of mothers had ceased breastfeeding. Breastfeeding continuation at eight weeks was negatively correlated with elevated BMI (P < 0.01). Breastfeeding cessation in mothers with elevated BMI correlated with psycho-social concerns (P < 0.05) and lack of previous breastfeeding experience (P < 0.01).

CONCLUSION

Elevated maternal BMI is prevalent in our community and significantly impacts the success of breastfeeding in the early post-natal period. The survey data have allowed targeted health responses to be developed.

Nutrition in developmental age: few rules to stay healthy

The first 1000 days of life represent a critical window for infants' and children's development. Overweight and insulin resistance, at the basis of non-communicable diseases (NCDs), are linked to various risk factors that begin in childhood, including children's diet. Italian data on infants' and children's dietary habits show higher intake of proteins, simple sugars, unhealthy fats and salt than recommended, while the iron intake is below requirement. We reviewed current literature analyzing observational studies, meta-analysis, systematic review and randomized clinical trials of the last 10 years (from 2009) on nutrition in developmental age, providing some few rules to abide by. Exclusive breastfeeding is recommended by World Health Organization for the first 6 months of life and it should be continued alongside the complementary feeding period until 12 months, or even afterward. Complementary feeding should not be started before the 17th week of age with energetically adequate foods, paying attention to limit protein intake and favoring iron-rich foods. Intake of simple sugars should be limited or avoided at all; it has been demonstrated that substituting sugar-sweetened beverages with water decreases body fatness development in adolescence. Quality of the ingested fats is more important than their quantity: polyunsaturated fatty acids should be preferred. Sodium intake should be limited in the first 24 months of life, as first prevention measure of arterial hypertension later in adulthood. Healthy eating habits are the first important step toward the prevention of NCDs.

Electronic Monitoring Of Mom's Schedule (eMOMS™): Protocol for a feasibility randomized controlled trial to improve postpartum weight, blood sugars, and breastfeeding among high BMI women

Background

Overweight and obesity are major risk factors for gestational diabetes among U.S. women. Evidence suggests that longer duration of breastfeeding among women with a history of gestational diabetes is associated with lower incidence of developing type 2 diabetes after pregnancy. Women may potentially benefit from a lifestyle change program that includes breastfeeding education and support.

Purpose

To describe the design and justification of a combined breastfeeding, national Diabetes Prevention Program (DPP)-based feasibility randomized controlled trial, the electronic Monitoring Of Mom's Schedule (eMOMS^TM) study. eMOMS^TM compares the feasibility and efficacy of three interventions on six-month postpartum weight loss among women with a BMI ≥25.

Methods

The intervention is delivered via Facebook and includes three groups: DPP and breastfeeding (eMOMS1); DPP only (eMOMS2); and Usual Care (eMOMS3). Recruitment is ongoing at two clinical sites (rural and urban). A total of 72 women, 24 per group, will be randomly assigned to one of the three groups. It is anticipated that women in eMOMS1 will have greater weight loss and increased length of breastfeeding at three and six months postpartum compared to women in eMOMS2 and eMOMS3. Additional data will be collected on metabolic markers, anthropometrics, physical activity, nutrition, breastfeeding, and depression. Program cost will be compared to that of traditionally scheduled group meetings. Expected study completion date: October 2021.

Conclusions

This study has the potential to define a high impact, cost effective intervention that can improve public health by reducing negative health outcomes associated with gestational diabetes among an at-risk population.

Prevalence and Associated Factors of Caesarean Section and its Impact on Early Initiation of Breastfeeding in Abu Dhabi, United Arab Emirates

The World Health Organization (WHO) recommends the early initiation of breastfeeding. Research shows that factors such as mode of delivery may interfere with the early initiation of breastfeeding. However, data in the United Arab Emirates (UAE) on these findings is limited. Thus, the aim of this study was to describe the prevalence of caesarean sections (CSs) and evaluate their effect on breastfeeding initiation among mothers of children under the age of two years in Abu Dhabi. Data were collected in clinical and non-clinical settings across various geographical areas in Abu Dhabi during 2017 using consent and structured questionnaires for interviews with mothers. Data analysis included both descriptive and inferential statistics. Among the 1624 participants, one-third (30.2%) reportedly delivered by CS, of which 71.1% were planned, while 28.9% were emergency CS. More than half of all mothers (62.5%) initiated early breastfeeding. Multivariable logistic regression indicated factors that were associated positively with CS included advanced maternal age, nationality, and obesity. However, gestational age (GA) was negatively associated with CS. This study shows that the prevalence of CS is high in Abu Dhabi, UAE. CS is associated with lower early initiation rates of breastfeeding. The early initiation rates of breastfeeding were 804 (79.2%) 95% confidence interval (CI) (76.4, 82.0), 162 (16.0%) 95% CI (10.4, 21.6), and 49 (4.8%) 95% CI (1.2, 10.8) among vaginal delivery, planned CS, and emergency CS, respectively. Regarding the mode of delivery, vaginal were 2.78 (Adjusted Odd Ratio (AOR)): CI (95%), (2.17–3.56, p < 0.001) times more likely related to an early initiation of breastfeeding. CS in general, and emergency CS, was the main risk factor for the delayed initiation of breastfeeding. The study provides valuable information to develop appropriate strategies to reduce the CS rate in UAE. Maternal literacy on CS choices, the importance of breastfeeding for child health, and additional guidance for mothers and their families are necessary to achieve better breastfeeding outcomes.

High Maternal Body Mass Index Is Associated with an Early-Onset of Overweight/Obesity in Pre-School-Aged Children in Malawi. A Multilevel Analysis of the 2015-16 Malawi Demographic and Health Survey

BACKGROUND

Overweight/obesity in young children is one of the most serious public health issues globally. We examined whether individual- and community-level maternal nutritional status is associated with an early onset of overweight/obesity in pre-school-aged children in Malawi.

DESIGN

Data were obtained from the 2015-16 Malawi Demographic and Health Survey (MDHS). The maternal nutritional status as body mass index and childhood overweight/obesity status was assessed by using the World Health Organization (WHO) recommendations. To examine whether the maternal nutritional status is associated with overweight/obesity in pre-school-aged children, two-level multilevel logistic regression models were constructed on 4023 children of age less than five years dwelling in 850 different communities.

RESULTS

The multilevel regression analysis showed that children born to overweight/obese mothers had increased odds of being overweight/obese [adjusted odds ratio (aOR) = 3.11; 95% confidence interval (CI): 1.13-8.54]. At the community level, children born to mothers from the middle (aOR: 1.68; 95% CI: 1.02-2.78) and high (aOR: 1.69; 95% CI: 1.00-2.90) percentage of overweight/obese women had increased odds of being overweight/obese. In addition, there were significant variations in the odds of childhood overweight/obesity in the communities.

CONCLUSIONS

Strategies aimed at reducing childhood overweight/obesity in Malawi should address not only women and their children but also their communities. Appropriate choices of nutrition, diet and physical activity patterns should be emphasized upon in overweight/obese women of childbearing age throughout pregnancy and beyond.

Comparison of national cross-sectional breast-feeding surveys by maternal education in Europe (2006-2016)

OBJECTIVE

Breast-feeding is an important determinant of health of mothers and their offspring. The present study aimed to compare breast-feeding rates across Europe disaggregated by maternal education and establish what proportion achieves at least 50 % exclusive breast-feeding (EBF) at 6 months.Design/SettingSecondary analysis of national or sub-national studies' breast-feeding data for EU Member States plus Norway and Iceland, published in 2006-2016. Nineteen EU Member States plus Norway reported rates of EBF and any breast-feeding disaggregated by maternal education, of which only thirteen could be matched to the International Standard Classification of Education.ParticipantsMothers and their infants aged 0-12 months.

RESULTS

Data on EBF rates at 6 and 4 months were found in only four and six countries, respectively. At 6 months, EBF rates of 49 % in Slovakia and 44 % in Hungary were closest to WHO's target of at least 50 % EBF. At 4 months, mothers with high education level in Denmark, the Netherlands and Germany had the highest EBF rates (71, 52 and 50 %, respectively). Mothers with low education level were less likely to initiate breast-feeding and cessation occurred early. The inequality gap ranged from 63 % in Irish mothers to no gap or very low levels of inequality in Poland, Sweden and Norway.

CONCLUSIONS

More mothers with high, compared with low, education initiate breast-feeding and practise EBF for longer. More European policies should be targeted to protect, support and promote breast-feeding, especially among mothers with only mandatory education.

Maternal Prepregnancy Body Mass Index, Gestational Weight Gain, and Cessation of Breastfeeding: A Systematic Review and Meta-Analysis

Background: Suboptimal breastfeeding, a major factor of maternal and child morbidity and mortality, has been reported around the world. Maternal weight status, as a significant variable influencing breastfeeding outcomes, needs to be studied sufficiently. Objective: This review is to explore the effect of different prepregnancy BMI and gestational weight gain (GWG) categories on breastfeeding initiation and cessation. Materials and Methods: Cohort studies were systematically searched in Embase, Web of Science, PubMed, and CINAHL databases from database establishment to February 2019. Summary risk ratio (RR) on breastfeeding initiation and cessation was estimated with the use of a random-effects model. Results: Thirty cohort studies were included in meta-analysis. Prepregnancy obesity was a risk factor for breastfeeding initiation (RR 1.49, 95% CI [1.33-1.67]), exclusive and any breastfeeding (ABF) duration (RR 1.26, 95% CI [1.17-1.36]; RR 1.34 95% CI [1.16-1.56]). Inadequate GWG was a risk factor for breastfeeding initiation (RR 1.27, 95% CI [1.08-1.49]). Excessive GWG was a risk factor for ABF duration when women were prepregnancy overweight and obese (RR 1.42 95% CI [1.32-1.53]; RR 1.89 95% CI [1.13-3.17]). Conclusion: If women are obese before pregnancy or gain excessive/inadequate weight during pregnancy, they are less likely to initiate and continue breastfeeding according to recommendation time. Hence, guidance about proper weight management to reproductive age women and consultation about recommended GWG to pregnant women should be fully implemented to improve breastfeeding practices. Besides, future research needs to find out the association between prepregnancy underweight status and breastfeeding outcomes.

Prepregnancy obesity as a risk factor for exclusive breastfeeding initiation in Japanese women

OBJECTIVES

Breastfeeding rates in many countries fall short of the World Health Organization's recommendations. It has been reported that exclusive breastfeeding (EBF) is negatively associated with obesity; however, the association varies with ethnicity, and little information is available from Asia. We explored whether prepregnancy body mass index (BMI) and gestational weight gain (GWG) were associated with initiation of EBF.

METHODS

We investigated 6125 Japanese women with full-term (37-42 wk of gestation) singleton babies between January 2010 and June 2013, in a hospital with the largest annual number of deliveries in Tokyo, Japan.

RESULTS

Successful EBF initiation was observed in 72% of women 1 mo after delivery. The average GWG was 10 kg in underweight (BMI < 18.5 kg/m²) and normal weight (BMI 18.5-24.9 kg/m²) women; 7 kg in overweight (BMI 25-29.9 kg/m²) women, and 4 kg in obese (BMI ≥ 30 kg/m²) women. After adjusting for covariates, stepwise modeling revealed that compared with women of normal weight, obesity (odds ratio [OR], 0.29; 95% confidence interval [CI], 0.16-0.53), and a single-unit increase in the GWG (OR, 0.98; 95% CI, 0.96-1.00) were significantly associated with unsuccessful EBF initiation. No statistical interaction was evident between prepregnancy BMI and GWG. Other significant risk factors for unsuccessful EBF initiation included older maternal age (P < 0.001), nulliparity (P < 0.001), cesarean delivery (P < 0.001), an earlier gestational week (P < 0.001), a light-for-date infant (P < 0.05), and mother-child separation for clinical reasons (P < 0.001).

CONCLUSIONS

This study suggested that prepregnancy obesity is a risk factor for EBF initiation among Japanese women.

Advocacy for Improving Nutrition in the First 1000 Days to Support Childhood Development and Adult Health

Maternal prenatal nutrition and the child's nutrition in the first 2 years of life (1000 days) are crucial factors in a child's neurodevelopment and lifelong mental health. Child and adult health risks, including obesity, hypertension, and diabetes, may be programmed by nutritional status during this period. Calories are essential for growth of both fetus and child but are not sufficient for normal brain development. Although all nutrients are necessary for brain growth, key nutrients that support neurodevelopment include protein; zinc; iron; choline; folate; iodine; vitamins A, D, B₆, and B₁₂; and long-chain polyunsaturated fatty acids. Failure to provide key nutrients during this critical period of brain development may result in lifelong deficits in brain function despite subsequent nutrient repletion. Understanding the complex interplay of micro- and macronutrients and neurodevelopment is key to moving beyond simply recommending a "good diet" to optimizing nutrient delivery for the developing child. Leaders in pediatric health and policy makers must be aware of this research given its implications for public policy at the federal and state level. Pediatricians should refer to existing services for nutrition support for pregnant and breastfeeding women, infants, and toddlers. Finally, all providers caring for children can advocate for healthy diets for mothers, infants, and young children in the first 1000 days. Prioritizing public policies that ensure the provision of adequate nutrients and healthy eating during this crucial time would ensure that all children have an early foundation for optimal neurodevelopment, a key factor in long-term health.

Influence of weight concerns on breastfeeding: Evidence from the Norwegian mother and child cohort study

Objectives

High body mass index (BMI) often predicts truncated breastfeeding, although why is unclear. We test a proposed mediating role of body concerns on breastfeeding initiation and child's age at weaning using longitudinal data for 55,522 mothers from the Norwegian Mother and Child Cohort Study (MoBa).

Methods

A linear regression‐based mediation analysis with bootstrapping estimates the indirect effects of BMI on breastfeeding decisions (ever‐initiation of breastfeeding, child's age at weaning, and duration of any breastfeeding beyond six months) through the variables of concern around prepregnancy weight and weight gains due to pregnancy.

Results

Contrary to prediction, Norwegian mothers with greater prepregnancy weight concerns had a higher likelihood of initiating breastfeeding. Concerns about weight gain during pregnancy, however, predicted earlier weaning. This relationship was the same for higher and lower BMI mothers.

Conclusion

In this very large sample, body image affects some breastfeeding decisions. However, this effect is independent of mother's body size.

A comparison of breastfeeding rates by obesity class

PURPOSE

The purpose of this study is to compare breastfeeding initiation rates for women across body mass index (BMI) classes, including normal BMI (18.50-24.99 kg/m²), overweight (25.00-29.99 kg/m²), obese (30.00-39.99 kg/m²), morbidly obese (40.00-49.99 kg/m²) and extreme obesity (≥50.00 kg/m²).

MATERIALS AND METHODS

Retrospective cohort of women with singleton pregnancies, delivering in St. John's, NL between 2002 and 2011. The primary outcome was any breastfeeding on hospital discharge. Breastfeeding rates across BMI categories were compared, using univariate analyses. Multivariate analysis included additional maternal and obstetric variables.

RESULTS

Twelve thousand four hundred twenty-two women were included: 8430 breastfed and 3992 did not breastfeed on hospital discharge. Progressively decreasing rates of breastfeeding were noted with increasing obesity class: normal BMI (71.1%), overweight (69.1%), obese (61.6%), morbidly obese (54.2%), and extremely obese women (42.3%). Multivariate analysis confirmed that increasing obesity class resulted in lower odds of breastfeeding: overweight (adjusted odds ratios (aOR) 0.86, 95%CI 0.76-0.98), obese (aOR 0.65, 95%CI 0.57-0.74), morbidly obese (aOR 0.57, 95%CI 0.44-0.74), and extreme obesity (aOR 0.37, 95%CI 0.19-0.74).

CONCLUSION

Women in higher obesity classes are progressively less likely to initiate breastfeeding. Women with the highest prepregnancy BMIs should be particularly counseled on the benefits of breastfeeding.

Mother's education and the risk of several neonatal outcomes: an evidence from an Italian population-based study

Background

Maternal socioeconomic disparities strongly affect child health, particularly in low and middle income countries. We assessed whether neonatal outcomes varied by maternal education in a setting where healthcare system provides universal coverage of health services to all women, irrespective of their socioeconomic status.

Methods

A population-based study was performed on 383,103 singleton live births occurring from 2005 to 2010 in Lombardy, an Italian region with approximately 10 million inhabitants. The association between maternal education, birthplace and selected neonatal outcomes (preterm birth, low birth weight, small-for-gestational age, low 5-min Apgar score, severe congenital anomalies, cerebral distress and respiratory distress) was estimated by fitting logistic regression models. Model adjustments were applied for sociodemographic, reproductive and medical maternal traits.

Results

Compared with low-level educated mothers, those with high education had reduced odds of preterm birth (Odds Ratio; OR = 0.81, 95% CI 0.77–0.85), low birth weight (OR = 0.78, 95% CI 0.70–0.81), small for gestational age (OR = 0.82, 95% CI 0.79–0.85), and respiratory distress (OR = 0.84, 95% CI 0.80–0.88).

Mothers born in a foreign country had higher odds of preterm birth (OR = 1.16, 95% CI 1.11–1.20), low Apgar score (OR = 1.18, 95% CI 1.07–1.30) and respiratory distress (OR = 1.19, 95% CI 1.15–1.24) than Italian-born mothers. The influence of maternal education on neonatal outcomes was confirmed among both, Italian-born and foreign-born mothers.

Conclusions

Low levels of education and maternal birthplace are important factors associated with adverse neonatal outcomes in Italy. Future studies are encouraged to investigate factors mediating the effects of socioeconomic inequality for identifying the main target groups for interventions.

Infant feeding counseling and knowledge are the key determinants of prelacteal feeding among HIV exposed infants attending public hospitals in Ethiopia

BACKGROUND

Despite the fact that breastfeeding promotes optimal health and growth for infants and young children, inappropriate feeding practice, such as prelacteal feeding increases the risk of neonatal death and illness and remains a public health problem in Ethiopia. Therefore, this study assessed the prevalence of prelacteal feeding and associated factors among HIV positive mothers with children aged 7-20 months attending government hospitals in North Gondar zone, northwest Ethiopia.

METHODS

An institution based cross-sectional study was conducted from February to March, 2016, at public hospitals of North Gondar Zone. Three hundred sixty-seven HIV positive mothers attending PMTCT clinics in government hospitals during the study period were included in the study. A multivariate logistic regression analysis was used to investigate factors associated with prelacteal feeding. The Adjusted Odds Ratio (AOR) with the corresponding 95% Confidence Interval (CI) was used to show the strength of association, and variables with a P-value of <0.05 were considered statistically significant.

RESULTS

In this study, the overall prevalence of prelacteal feeding was 19.1% (95% CI: 15-23). According to the multivariate analysis, prelacteal feeding was associated with fathers with no formal education (AOR = 5.85; 95% CI: 2.02, 16.92), lack of infant feeding counseling (AOR = 3.36; 95% CI: 1.27, 8.85), discarding the colostrum (AOR = 5.16; 95% CI: 2.32, 11.45), inadequacy of antenatal care visit (AOR = 0.07; 95% CI: 0.03, 0.15), and high IYCF knowledge (AOR = 0.10; 95% CI: 0.03, 0.30).

CONCLUSION

In this study, the prevalence of prelacteal feeding was high. Furthermore, father's education, colostrum feeding, infant feeding counseling, ANC visit, and IYCF knowledge were significantly associated with prelacteal feeding. As a result, strengthening maternal health care utilization, breastfeeding counseling, and IYCF knowledge are essential to address the high burden of prelacteal feeding.

Exploring the need for interventions to manage weight and stress during interconception

Interventions to manage weight and stress during the interconception period (i.e., time immediately following childbirth to subsequent pregnancy) are needed to promote optimal maternal and infant health outcomes. To address this gap, we summarize the current state of knowledge, critically evaluate the research focused on weight and stress management during the interconception period, and provide future recommendations for research in this area. Evidence supports the importance of weight and stress management during the reproductive years and the impact of weight on maternal and child health outcomes. However, evidence-based treatment models that address postpartum weight loss and manage maternal stress during the interconception period are lacking. This problem is further compounded by inconsistent definitions and measurements of stress. Recommendations for future research include interventions that address weight and stress tailored for women in the interconception period, interventions that address healthcare providers' understanding of the significance of weight and stress management during interconception, and long-term follow-up studies that focus on the public health implications of weight and stress management during interconception. Addressing obesity and stress during the interconception period via a reproductive lens will be a starting point for women and their families to live long and healthy lives.

Is the Risk of Preterm Birth and Low Birth Weight Affected by the Use of Antidepressant Agents during Pregnancy? A Population-Based Investigation

Background

Untreated depression during pregnancy increases the risk of morbidity and mortality in the mother and child. Therefore, specific treatments are required for this population.

Objective

The study aimed to investigating the effect of antidepressant medication used during pregnancy with reference to the risk of preterm birth (PTB) and low birth weight (LBW).

Methods

A population-based study was carried out with data provided by the healthcare utilization database of Lombardy, an Italian region with about ten million inhabitants. The study included 384,673 births from 2005 to 2010. Maternal use of antidepressants before and during pregnancy was investigated. Log-binomial regression was used to estimate the association between the use of antidepressants during pregnancy, compared to the non-use or use just before pregnancy, and the prevalence ratio of PTB and LBW.

Results

Women who used antidepressants during pregnancy had a 20% (95% CI: 10–40%) increased prevalence of both PTB and LBW compared to those who never used antidepressants. There was no evidence that women who used antidepressants during pregnancy had a higher prevalence of the considered outcomes compared to women who used antidepressants before pregnancy, but stopped during pregnancy. Such findings were confirmed by considering separately the effects of SSRIs and other antidepressants together.

Conclusions

Our findings suggest that depression in itself, rather than antidepressant medication, might be implicated in the causal pathway of PTB and LBW.

Obese women experience multiple challenges with breastfeeding that are either unique or exacerbated by their obesity: discoveries from a longitudinal, qualitative study

Obese women are at risk for shorter breastfeeding duration, but little is known about how obese women experience breastfeeding. The aim of this study was to understand obese women's breastfeeding experiences. We enrolled pregnant women in upstate New York, who were either obese [n = 13; body mass index (BMI) ≥30 kg/m² ] or normal weight (n = 9; BMI 18.5-24.9 kg/m² ) before conception and intended to breastfeed. A longitudinal, qualitative study was conducted from February 2013 through August 2014 with semi-structured interviews during pregnancy and at specific times post-partum through 3 months. Interviews were audio recorded, transcribed and analyzed using content analysis. Themes that emerged in analysis were compared between obese and normal-weight women. Differences were identified and described. Prenatally, obese women expressed less confidence about breastfeeding than normal-weight women. Post-partum, obese women and their infants had more health issues that affected breastfeeding, such as low infant blood glucose. Compared with normal-weight women, they also experienced more challenges with latching and positioning their infants. Breastfeeding required more time, props and pillows, which limited where obese women could breastfeed. Obese women also experienced more difficulty finding nursing bras and required more tangible social support than normal-weight women. In conclusion, obese women experienced more challenges than women of normal weight; some challenges were similar to those of normal-weight women but were experienced to a greater degree or a longer duration. Other challenges were unique. Obese women could benefit from targeted care prenatally and during the hospital stay as well as continued support post-partum to improve breastfeeding outcomes. © 2016 John Wiley & Sons Ltd.

Maternal weight status, diet, and supplement use as determinants of breastfeeding and complementary feeding: a systematic review and meta-analysis

CONTEXT

Infant feeding practices are influenced by maternal factors.

OBJECTIVE

The aim of this review is to examine the associations between maternal weight status or dietary characteristics and breastfeeding or complementary feeding.

DATA SOURCES

A systematic literature search of the Embase, Cochrane Library, Google Scholar, MEDLINE, PubMed, and Web of Science databases was performed.

STUDY SELECTION

Interventional and cohort studies in healthy mothers and infants that reported on maternal weight status, diet, or supplement use were selected.

DATA EXTRACTION

Outcomes assessed included delayed onset of lactogenesis; initiation, exclusivity, duration, and cessation of breastfeeding; and timing of complementary feeding.

DATA ANALYSIS

Eighty-one studies were included. Maternal underweight, diet, and supplement use were not associated with infant feeding practices. Obese women had a relative risk of failure to initiate breastfeeding (risk ratio [RR] = 1.23; 95%CI, 1.03-1.47) and a delayed onset of lactogenesis (RR  =  2.06; 95%CI, 1.18-3.61). The RR for breastfeeding cessation was 1.11 (95%CI, 1.07-1.15) per increase in category of body mass index.

CONCLUSIONS

Prevention of obesity in women of reproductive age, as well as counseling of obese women after delivery, could be targeted to improve infant feeding practices.

The Impact of Maternal Obesity on Breastfeeding

OBJECTIVE

To compare the rate of any breastfeeding at the time of postpartum hospital discharge between obese women (BMI ≥ 30.00 kg/m(2)) and women with a normal BMI (18.50 to 24.99 kg/m(2)).

METHODS

We conducted a retrospective cohort study of women with live, singleton pregnancies who delivered in St. John's, Newfoundland and Labrador between 2002 and 2011, using data from the Newfoundland and Labrador provincial perinatal registry. The primary outcome was any breastfeeding at the time of discharge from hospital. Secondary analysis included comparison of breastfeeding rates by class of obesity. We compared additional maternal and neonatal outcomes between women who were breastfeeding at discharge and those who were not. Univariate and multivariate logistic regression analyses were performed, and adjusted odds ratios (aORs) and 95% CIs were calculated.

RESULTS

We included 12 831 women with BMI data available in the study: 8676 were breastfeeding and 4155 were not at the time of postpartum discharge. Obese women were less likely to breastfeed than women with normal weight (60.0% vs. 71.7%) (aOR 0.63; 95% CI 0.55 to 0.71). Multivariate analysis showed a significant effect on the primary outcome of a mother's age (aOR 1.03; 95% CI 1.02 to 1.05), nulliparity (aOR 1.73; 95% CI 1.51 to 1.98), being partnered (aOR 1.57; 95% CI 1.34 to 1.84), working (aOR 1.10; 95% CI 1.02 to 1.19), having higher education (aOR 1.48; 95% CI 1.38 to 1.60), smoking (aOR 0.35; 95% CI 0.29 to 0.43), having gestational diabetes (aOR 0.70; 95% CI 0.5 to 0.92), pre-existing hypertension (aOR 0.58; 95% CI 0.39 to 0.87), gestational hypertension (aOR 0.67; 95% CI 0.55 to 0.82), and undergoing general anaesthesia (aOR 0.41; 95% CI 0.22 to 0.77).

CONCLUSION

Obesity is an independent risk factor for not breastfeeding at the time of postpartum discharge from hospital. It is important to counsel women on the benefits of breastfeeding, emphasizing these particularly in women with a high pre-pregnancy BMI.

Factors associated with prelacteal feeding in the rural population of northwest Ethiopia: a community cross-sectional study

Background

Prelacteal feeding has continued as a deep-rooted nutritional malpractice in developing countries. Prelacteal feeding is a barrier for implementation of optimal breastfeeding practices, and increases the risk of neonatal illness and mortality. However, its determinants are not well studied, which are essential to design intervention. This study aimed to assess the prevalence and determinants of prelacteal feeding among mothers with children aged 6–24 months in the rural population of northwest Ethiopia.

Methods

A community based cross-sectional study was conducted in Dabat Health and Demographic Surveillance System site, Dabat district, northwest Ethiopia from May 01 to June 29, 2015. Eight hundred and twenty-two mother-child pairs were included in the study. A pretested and structured questionnaire was used to collect data. Multivariable logistic regression analysis was carried out to identify the determinants of prelacteal feeding.

Results

In this community, about 26.8 % of children were given prelacteal feeds. The odds of prelacteal feeding was higher among mothers with a poor knowledge of Infant and Young Child Feeding (IYCF) (Adjusted Odds Ratio [AOR] = 3.82; 95 % Confidence Interval [CI] 2.42, 6.04), who gave birth at home (AOR = 3.74; 95 % CI 2.12, 6.60), and who were in the lowest wealth status (AOR = 2.11; 95 % CI 1.35, 3.31).

Conclusions

Prelacteal feeding was common in the study area, and significantly associated with a poor household wealth status, poor maternal knowledge of IYCF, and giving birth at home. Thus, emphasis should be given to improve mothers IYCF knowledge and utilization of institutional delivery. Moreover, special attention should be given to mothers with poor socio-economic status to reduce the practice of prelacteal feeding.

Changing Societal and Lifestyle Factors and Breastfeeding Patterns Over Time

BACKGROUND

Breastfeeding is an important determinant of early infant immune function and potentially future health. Although numerous studies have reported rising breastfeeding initiation rates and duration, few longitudinally investigated the impact of shifting societal and lifestyle factors on breastfeeding patterns in developed nations.

METHODS

The Ulm Birth Cohort Study (UBCS) and Ulm SPATZ Health Study (SPATZ) cohorts consist of newborns and their mothers recruited, respectively, from 2000 to 2001 and 2012 to 2013 at the University Medical Center Ulm, Germany. Cox proportional hazards models were used to estimate crude and mutually adjusted hazard ratios for study effect (time trend) and individual risk factors on noninitiation and duration of predominant and total breastfeeding.

RESULTS

Compared with UBCS mothers, SPATZ mothers had lower cessation rates of both predominant breastfeeding by 4 months and total breastfeeding by 6 months: hazard ratio (95% confidence interval) 0.79 (0.67-0.93) and 0.71 (0.60-0.82), respectively. However, this crude time trend was limited to mothers with higher educational achievement. Similar time trend effects were observed among less educated mothers only after adjustment for early cessation risk factors. Mutually adjusted hazard ratios for individual risk factors were similar in both studies: low education, high BMI, smoking within 6 weeks of delivery, and cesarean delivery were associated with early breastfeeding cessation beginning at 6 weeks. In addition, actively abstaining from drinking alcohol was associated with lower rates of early cessation.

CONCLUSIONS

Our results suggest widening socioeconomic disparity in breastfeeding and potentially subsequent child health, which may require new targeted interventions.

Predictive Models for Characterizing Disparities in Exclusive Breastfeeding Performance in a Multi-ethnic Population in the US

OBJECTIVES

Maternal lactation performance varies across populations, yet the relative impact of maternal sociodemographics, perinatal factors, and birth outcomes on disparities in exclusive breastfeeding (XBR) outcomes is not well known. We aimed to develop predictive models and compare the relative contribution of predictors for XBR initiation and XBR ≥ 6 months.

METHODS

Infant feeding data were obtained from women with children aged 0-6 years (n = 1471) in a multi-ethnic cross-sectional study in the US (2011-2012). We compared discriminant ability of predictors for ever XBR and XBR ≥ 6 months using discriminant function analysis, respectively. We also calculated adjusted ORs for factors associated with XBR outcomes and breast-bottle feeding (BrBot) subgroups.

RESULTS

Maternal sociodemographics (education level, marital status, nativity, and age at childbirth) had greater discriminating abilities in predicting ever XBR and XBR ≥ 6 months than birth outcomes and perinatal factors. Foreign-born women were two-fold more likely to initiate XBR but not necessarily continue to 6 months compared to their US-born counterparts. Factors associated with BrBot subgroups differed from those associated with XBR outcomes, whereas maternal age was the only predictor consistently associated with ever XBR, XBR ≥ 6 months, and BrBot subgroups. The areas under the receiver operating characteristic curves for models predicting ever XBR and XBR ≥ 6 months were 0.88 (95 % CI 0.85, 0.91) and 0.90 (95 % CI 0.88, 0.93), respectively.

CONCLUSIONS

Findings underscore the importance of educational, clinical, and social support to promote XBR in mothers with sociodemographic factors predictive of none or poor XBR outcomes.

Lactation and appetite-regulating hormones: increased maternal plasma peptide YY concentrations 3-6 months postpartum

Breast-feeding is associated with maternal hormonal and metabolic changes ensuring adequate milk production. In this study, we investigate the impact of breast-feeding on the profile of changes in maternal appetite-regulating hormones 3-6 months postpartum. Study participants were age- and BMI-matched lactating mothers (n 10), non-lactating mothers (n 9) and women without any history of pregnancy or breast-feeding in the previous 12 months (control group, n 10). During study sessions, young mothers breast-fed or bottle-fed their babies, and maternal blood samples were collected at five time points during 90 min: before, during and after feeding the babies. Outcome parameters were plasma concentrations of ghrelin, peptide YY (PYY), leptin, adiponectin, prolactin, cortisol, insulin, glucose and lipid values. At baseline, circulating PYY concentrations were significantly increased in lactating mothers (100·3 (se 6·7) pg/ml) v. non-lactating mothers (73·6 (se 4·9) pg/ml, P=0·008) and v. the control group (70·2 (se 9) pg/ml, P=0·021). We found no differences in ghrelin, leptin and adiponectin values. Baseline prolactin concentrations were over 4-fold higher in lactating mothers (P<0·001). Lactating women had reduced TAG levels and LDL-cholesterol:HDL-cholesterol ratio, but increased waist circumference, when compared with non-lactating women. Breast-feeding sessions further elevated circulating prolactin (P<0·001), but induced no acute effects on appetite-regulating hormones. In summary, one single breast-feeding session did not acutely modulate circulating appetite-regulating hormones, but increased baseline PYY concentrations are associated with prolonged lactation. PYY might play a role in the coordination of energy balance during lactation, increasing fat mobilisation from maternal depots and ensuring adequate milk production for the demands of the growing infant.
