Breastfeeding behaviours in women with obesity; associations with weight retention and the serum metabolome: a secondary analysis of UPBEAT. Int J Obes (Lond) 2024:10.1038/s41366-024-01576-6. [PMID: 39048696 DOI: 10.1038/s41366-024-01576-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Revised: 06/17/2024] [Accepted: 07/01/2024] [Indexed: 07/27/2024]
Abstract
BACKGROUND/OBJECTIVES Maternal obesity is associated with a decreased intention and initiation of breastfeeding as well as a shortened duration of breastfeeding. This analysis was undertaken to identify breastfeeding behaviours, and relationships with maternal anthropometry and the serum metabolome at 6-months postpartum in an ethnically diverse cohort of women with obesity. SUBJECTS/METHODS A cohort analysis of 715 women from the UK Pregnancies Better Eating and Activity Trial (UPBEAT); a multi-centre randomised controlled trial of an antenatal lifestyle intervention in women with obesity. Maternal data were collected in early pregnancy and included body mass index (BMI), socio-demographic characteristics and anthropometry. At 6-months postpartum, breastfeeding behaviours, anthropometry and 158 maternal metabolic measures from blood samples were recorded. Kaplan-Meier curves of breastfeeding duration were constructed and were stratified by obesity class (I: BMI 30.0-34.9 kg/m2, II: 35.0-39.9 kg/m2, III: ≥40.0 kg/m2). Relationships between breastfeeding behaviours, socio-demographic characteristics, the metabolome, and anthropometry were determined using regression analyses. RESULTS Eighty-two percent (591/715) of the cohort-initiated breastfeeding and at the 6-month follow-up 40% (283/715) were breastfeeding exclusively or partially. Duration of exclusive breastfeeding decreased with increasing BMI: Compared to BMI class I (mean 90.4 ± 64 days) the difference in mean for classes II and III were -15.8 days (95% confidence interval: -28.5, -3.1, p < 0.05) and -16.7 (95% CI: -32.0 to -1.35, p < 0.05), respectively. Compared to no breastfeeding, any breastfeeding at 6-months postpartum was associated with improvements in metabolites towards a healthier profile, reduced weight retention by -1.81 kg (95% CI -0.75, -2.88, p < 0.05 ) and reduced anthropometric measures, including mid-upper arm and hip circumferences. The breastfeeding related changes in anthropometry were not evident in women of Black ethnicity. CONCLUSIONS Greater emphasis on enabling breastfeeding for women with obesity could improve duration, women's weight management and metabolic health. The lack of breastfeeding related anthropometric effects in Black women requires further investigation. CLINICAL TRIAL REGISTRY ISRCTN reference 89971375.

Abstract
Inequalities in breastfeeding programmes and practices have slowed global progress in providing the life-saving protection of breastfeeding for millions of infants despite well-known life-long impacts. As breastfeeding interventions are scaled up, inequalities in coverage and breastfeeding practices should be tracked, particularly in disadvantaged groups, who are likely to suffer the most serious health and developmental impacts of poor childhood nutrition. The literature provides evidence of inequalities in breastfeeding practices, but research is limited on socioeconomic disparities in the coverage of breastfeeding interventions. This paper (1) compares inequalities in breastfeeding practices in intervention and nonintervention areas and (2) documents inequalities in programme coverage by type of intervention. We disaggregated endline evaluation surveys in Bangladesh, Burkina Faso and Vietnam, where rigorous evaluations had documented significant overall improvements, and analysed whether inequalities in breastfeeding practices and programme coverage differed by treatment areas. We used Erreygers index to quantify inequalities and found that breastfeeding practices were largely pro-poor; intervention coverage was not consistently pro-poor. While counselling coverage often favoured women from the poorest quintile, public education/media coverage consistently favoured better-off women. Inequalities favoured more educated mothers in the coverage of combined interventions. None of the programmes had explicit equality objectives. The results indicate the need for introducing specific actions to reduce inequalities in breastfeeding policies and programmes. This is a priority unfinished agenda for nutrition programming.

Complex intertwined association between breastfeeding practices and household food insecurity: Systematic review and meta-analysis. MATERNAL & CHILD NUTRITION 2024:e13696. [PMID: 38960401 DOI: 10.1111/mcn.13696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 06/14/2024] [Accepted: 06/19/2024] [Indexed: 07/05/2024]
Abstract
Breastfeeding offers ideal food and nutrition for infants; however, structural barriers may amplify breastfeeding inequities. We aimed to identify whether household food insecurity (HFI) is associated with exclusive and continued breastfeeding (EBF and CBF) as recommended by the World Health Organization/United Nations Children's Fund (UNICEF) Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis, literature searches using 'breastfeeding', 'food insecurity' and 'infant' terms were conducted in PubMed/MEDLINE, Embase, CINAHL, Global Health and LILACS from inception through November 2023, without language restrictions, yielding 1382 publications (PROSPERO:CRD42022329836). Predetermined eligibility criteria yielded the 12 included studies (nine cross-sectional and three cohorts). The risk of bias was assessed through the Effective Public Health Practice Project. Meta-analysis was performed for studies assessing EBF (n = 10), and metaregression was used to explore heterogeneity across studies. Prevalence of EBF ranged from 1.6% to 85.3%, with a lower prevalence among HFI. The pooled effect of the association between HFI and EBF presented an odds ratio (OR) of 0.61 (95% CI = 0.49-0.76) with consistent results across marginal (OR = 0.72, 95% CI = 0.55-0.94), moderate (OR = 0.59, 95% CI = 0.41-0.84) and severe HFI (OR = 0.49, 95% CI = 0.32-0.76). High heterogeneity was found only when HFI was dichotomized. The prevalence of CBF ranged from 35.4% to 78.0%, with inconsistent prevalence among HFI; a meta-analysis was not performed due to the low number of studies (n = 3). We concluded that HFI levels are associated with lower odds of EBF. Integrating service and policy-level strategies, such as screening, referrals, skilled breastfeeding counseling and access to comprehensive nutrition and social programs, could reduce structural inequities and promote adherence to the World Health Organization/UNICEF breastfeeding recommendations among food-insecure families.

Abstract
BACKGROUND Birthmark Doula Collective, a cooperative that provides doula and lactation services in the Greater New Orleans area, mounted an emergency response after two Category 4 storms: Hurricane Laura (2020) and Hurricane Ida (2021). The response included activating a no-cost emergency perinatal and infant feeding hotline. Both disasters coincided with a resurgence of COVID-19 infections in Louisiana. RESEARCH AIM The aim of this study is to understand how an emergency perinatal and infant feeding hotline supported infant and young child feeding in emergencies during hurricanes in Louisiana. METHOD This study used a cross-sectional, retrospective qualitative design in a population with low breastfeeding rates. We conducted a content analysis of 97 hotline call logs from Hurricanes Laura and Ida, focus groups with lactation support providers who staffed the hotline during either storm (n = 5), and interviews with mothers who called during Hurricane Ida (n = 2). Focus groups and interviews lasted 30 and 60 minutes, respectively. Transcripts were analyzed using thematic analysis techniques. RESULTS Call logs revealed infant feeding needs (e.g., mastitis, low milk supply, relactation, and infant formula requests) and non-infant feeding needs (e.g., infant supplies, perinatal and infant care referrals, shelter information). Infant formula was the most requested supply during both hurricanes. Maternal participants discussed family vulnerabilities during Hurricane Ida. Staff described training and strategies to provide support while maintaining their own well-being. CONCLUSION Providing a free emergency hotline service is one way to support pregnant and postpartum people and their families seeking infant feeding advice, supplies, and support in the immediate aftermath of a disaster.

The epidemiology and associated factors of non-exclusive breastfeeding: a comparative cross-sectional study of livelihood-secure and insecure areas. Front Nutr 2024; 11:1347780.

Abstract
Introduction Regardless of national commitment, non-exclusive breastfeeding (NEBF) is a public health problem that worsens over time. It can be associated with sociodemographic, economic, and environmental factors and may vary depending on livelihood security. Hence, this study aimed to determine the magnitude of NEBF and identify its associated factors by considering two areas with varied degrees of livelihood security. Methods This study represented a comparative cross-sectional survey of 1,060 under 6 months (u6m) infant-mother pairs. Both descriptive and analytic statistics were evaluated using STATA version 17 packages. A binary logistic regression was used to identify associated factors of NEBF. The odds ratio (OR) with a 95% confidence interval (CI) was used to measure the significance of the association at a p-value of <0.05. Results The pooled magnitude of 51% of NEBF mothers (95% CI: 48.0, 54.0) was 53.1% (95% CI: 49.2, 57.0) and 48.1% (95% CI: 43.4, 52.8) in livelihood-secure and livelihood-insecure areas, respectively. The lack of recollecting the infant's birth date by mothers (AOR = 2.4; 95% CI = 1.15-4.40) had the highest odds of NEBF while household heads with tertiary education (AOR = 0.14; 95% CI = 0.01-0.54) and the poorest households (AOR = 0.43; 95%CI = 0.20-0.82) had the lowest odds of NEBF in livelihood-secure areas but not in livelihood-insecure areas. Moreover, mothers with male infants (AOR = 1.9; 95% CI = 1.18-2.92) had high odds of NEBF in livelihood-insecure areas but not in livelihood-secure areas. Infants of 2 to less than 4-month-old (AOR = 8.5; 95% CI = 3.47-18.63) and 4 to less than 6-month-old (AOR = 22.2; 95% CI = 8.02-51.97) in livelihood-secure areas and infants of 2 to less than 4-month-old (AOR = 4.3; 95% CI = 1.29-11.67) and 4 to less than 6-month-old (AOR = 8.3; 95% CI = 2.44-22.39) in livelihood-insecure areas had high odds of NEBF. Conclusion Over half of the mothers were practicing NEBF, which represents a failure to meet national and international targets. Area vulnerability to livelihood security modifies factors of NEBF. Male infants in insecure areas, infants of unknown age in secure areas, and infants aged 2 months or older, regardless of setting, were more vulnerable to NEBF. However, households with the lowest wealth and higher household head educational status in livelihood-secure areas were less vulnerable to NEBF. Hence, livelihood-based interventions targeting mothers of 2 to less than 6-month-old infants, with emphasis on these factors, may help address and reduce NEBF.

Abstract
Background: In the United States, 11.1% of households experience food insecurity; however, pregnant women are disproportionately affected. Maternal food insecurity may affect infant feeding practices, for example, through being a source of chronic stress that may alter the decision to initiate and continue breastfeeding. Thus, we sought to determine whether prenatal food insecurity was associated with breastfeeding (versus not) and exclusive breastfeeding duration among Oregon women. Method: The Oregon Pregnancy Risk Assessment Monitoring System (PRAMS) data of live births from 2008 to 2015 and the Oregon PRAMS-2 follow-up survey were used (n = 3,624) in this study. Associations with breastfeeding initiation and duration were modeled with multivariable logistic regression and accelerated failure time (AFT), respectively. Models were adjusted for maternal sociodemographic and pre-pregnancy health characteristics. Results: Nearly 10% of women experienced prenatal food insecurity. For breastfeeding initiation, unadjusted models suggested non-significant decreased odds (odds ratio (OR) 0.88 [confidence intervals (CI): 0.39, 1.99]), whereas adjusted models revealed a non-significant increased odds (OR 1.41 [CI: 0.58, 3.47]). Unadjusted AFT models suggested that food-insecure mothers had a non-significant decrease in exclusive breastfeeding duration (OR 0.76 [CI: 0.50, 1.17]), but adjustment for covariates attenuated results (OR 0.89 [CI: 0.57, 1.39]). Conclusions: Findings suggest minimal differences in breastfeeding practices when exploring food security status in the prenatal period, though the persistence of food insecurity may affect exclusive breastfeeding duration. Lower breastfeeding initiation may be due to other explanatory factors correlated with food insecurity and breastfeeding, such as education and marital status.

Abstract
The climate crisis is an emerging global challenge that poses potential risks to breastfeeding practices and outcomes. There are multifaceted effects of climate change affecting the breastfeeding dyad across environmental, societal, and human health dimensions. Breastfeeding support in the face of climate change will require solutions at the structural level-healthcare, community, and workplace settings-and at the mother-infant dyad level. Breastfeeding can additionally be an adaptive response to crisis situations and can mitigate some of the environmental challenges associated with climate change. Despite the undeniable significance of climate change on breastfeeding (and vice versa), our perspective as experts in the field is that this topic has not been systematically addressed. Although we highlight some of the challenges, potential solutions, and co-benefits of breastfeeding in the context of climate change, there are numerous issues that could be further explored and necessitate additional preparedness planning.

Abstract
Human infants are born to breastfeed. While 50% of lactating persons struggle to make enough milk, there are no governmentally-approved drugs to enhance lactation1. Here, we engineer a variant of the naturally-occurring driver of lactation, the hormone Prolactin, to increase its serum half-life and produce a viable drug candidate. Our engineered variant, Prolactin-eXtra Long-acting (Prolactin-XL), is comprised of endogenously active human prolactin fused to an engineered human IgG Fc domain designed to overcome the unique drug development challenges specific to the lactating person-infant dyad. Our Prolactin-XL has a serum half-life of 70.9h in mice, 2,625-fold longer than endogenously active prolactin alone (70.9h v. 0.027h). We demonstrate that Prolactin-XL increases milk production and restores growth of pups fed by dams with pharmacologically-ablated lactation. We show that Prolactin-XL-enhanced lactation is accompanied by reversible, lactocyte-driven changes in mammary gland morphology. This work establishes long-acting prolactins as a potentially powerful pharmacologic means to combat insufficient lactation.
