The impact of the Baby-Friendly Hospital Initiative on breastfeeding rates at maternity units in France.

The Baby-Friendly Hospital Initiative (BFHI) is associated with improved breastfeeding outcomes in many high-income countries including the UK and the USA, but its effectiveness has never been evaluated in France. We investigated the impact of the BFHI on breastfeeding rates in French maternity units in 2010, 2016 and 2021 to assess if the BFHI aids to reduce inequalities in breastfeeding. We examined breastfeeding in maternity units (exclusive, mixed and any breastfeeding) in mothers of singleton full-term newborns using the 2010 (n = 13 075), 2016 (n = 10 919) and 2021 (n = 10 209) French National Perinatal Surveys. We used mixed-effect hierarchical multinomial regression models adjusting for neonatal, maternal, maternity unit and French administrative department characteristics, and tested certain interactions. The adjusted rate of exclusive breastfeeding was higher by +5.8 (3.4-8.1) points among mothers delivering in BFHI-accredited maternity units compared with those delivering in non-accredited units. When compared with average-weight newborns, this difference was sharper for infants with low birthweight: +14.9 (10.0-19.9) points when their birthweight was 2500 g. Mixed breastfeeding was lower by -1.7 points (-3.2-0) in BFHI-accredited hospitals, with no notable difference according to the neonatal or maternal characteristics. Mothers delivering in BFHI-accredited maternity units had higher exclusive breastfeeding rates and lower mixed breastfeeding rates than those delivering in non-accredited maternity units. The positive impact of the BFHI was stronger among low-birthweight neonates, who are less often breastfed, helping reduce the gap for this vulnerable group while favouring mothers with higher education levels.

Racializing Motherhood and Maternity Care in News Representations of Breastfeeding.

Racial inequalities in breastfeeding have been a U.S. national concern, prompting health science research and public discourse. Social science research reveals structural causes, including racism in labor conditions, maternity care practices, and lactation support. Yet research shows that popular and health science discourses disproportionately focus on individual and community factors, blaming Black women and communities for unequal breastfeeding rates. This study examines how scientific reports are communicated to the public through a critical analysis of 104 U.S. news articles reporting research on racial disparities in breastfeeding. Findings show that articles acknowledge unequal treatment within maternity care but justify it by presenting Black patients as overburdening the maternity care systems they use due to low socioeconomic status, welfare dependency, poor family support, and poor health. Through these representations, articles co-construct racialized motherhood and maternity care systems in ways that hide manifestations of obstetric racism and combat social support for systemic change.

Breastfeeding rates in England during the Covid-19 pandemic and the previous decade: Analysis of national surveys and routine data.

Few studies have compared breastfeeding rates before and during the pandemic using comparable data across time. We used data from two national maternity surveys (NMS) to compare breastfeeding rates in England before and during the pandemic. Analysis was conducted using the NMS from 2018 (pre-pandemic; n = 4,509) and 2020 (during the pandemic; n = 4,611). The prevalence of breastfeeding initiation, and 'any' breastfeeding and exclusive breastfeeding (EBF) at 6 weeks and 6 months were compared between these surveys. Data were interpreted in the context of underlying trends in these prevalences from previous NMS (from 2010 and 2014), and annual routine data for England (from 2009-10 to 2020-21). Modified Poisson regression was used to estimate adjusted risk ratios (aRR) for the effect of birth during the pandemic (2020 versus 2018) on breastfeeding, with adjustment for sociodemographic and birth-related factors. Breastfeeding initiation and any breastfeeding at 6 weeks remained relatively constant in the NMS and the routine data. Birth during the pandemic was associated with a 3 percentage point decrease in EBF at 6 weeks in the NMS (aRR 0.92, 95%CI: 0.87, 0.98 for pandemic versus pre-pandemic), but a smaller decrease in the routine data. Birth during the pandemic was associated with a 3 percentage point increase in any breastfeeding at 6 months in the NMS (aRR 1.05, 95%CI: 1.00, 1.10). Breastfeeding varied across different groups of women in the NMS (i.e. marked inequalities), but the small changes observed between the pandemic and pre-pandemic NMS were broadly similar across the sociodemographic and birth-related factors examined (i.e. no change in inequalities). Breastfeeding initiation and any breastfeeding at 6 weeks in England were unaffected by the pandemic, and the persistent inequalities in breastfeeding did not widen. Services should aim to reduce these inequalities in breastfeeding which have been documented since the 1970s.

Maternal and child factors associated with timely initiation of breastfeeding in sub-Saharan Africa

BackgroundThe probability of not breastfeeding within the first hour after delivery (timely initiation of breastfeeding) is particularly pronounced in sub-Saharan Africa. In this study, we examined the maternal and child factors associated with timely initiation of breastfeeding in sub-Saharan Africa.MethodsWe pooled data from 29 sub-Saharan African countries’ Demographic and Health Surveys conducted from 2010 to 2018. A total of 60,038 childbearing women were included. Frequencies, percentages, and binary logistic regression analyses were carried out. Binary logistic regression was used to examine the maternal and child factors associated with timely initiation of breastfeeding and the results were presented as adjusted odds ratios (aOR) at 95% confidence interval (CI). ResultsWe found a prevalence of 55.81% of timely initiation of breastfeeding in the sub-region. The country with the highest prevalence of timely initiation of breastfeeding was Burundi (86.19%), whereas Guinea had the lowest prevalence (15.17%). The likelihood of timely initiation of breastfeeding was lower among married women, compared to never married women (aOR 0.91; 95% CI 0.85, 0.98); working women compared to non-working women (aOR 0.90; 95% CI 0.87, 0.93); women who watched television at least once a week, compared to those who never watched television (aOR 0.74; 95% CI 0.70, 0.78); women who delivered through caesarean section, compared to vaginal birth (aOR 0.30; 95% CI 0.27, 0.32); and those with multiple births, compared to those with single births (aOR 0.67; 95% CI 0.59, 0.76). Women who lived in Central Africa were less likely to initiate breastfeeding timely compared to those who lived in West Africa (aOR 0.80; 95% CI 0.75, 0.84).ConclusionsThe findings call for the need for a behavioural change communication programmes, targeted at timely initiation of breastfeeding, to reverse and close the timely initiation of breastfeeding gaps stratified by the maternal and child factors. Prioritising policies to enhance timely initiation of breastfeeding is needed, particularly among Cental African countries where timely initiation of breastfeeding remains a challenge. Sufficient supportive care, especially for mothers with multiple births and those who undergo caesarean section, is needed to resolve timely initiation of breastfeeding inequalities.

Trends in social inequalities in breastfeeding and infant formulas in Latin American countries between the 1990 and 2010 decades.

To analyse trends of social inequality in breastfeeding and infant formula (IF) use in Latin America between 1990 and 2010 decades. Time-series cross-sectional study with data from Demographic and Health Surveys. We described the prevalence of exclusive breastfeeding (EBF), breastfeeding between 6 and 12 months (BF6-12) and IF for infants under 6 months (IF < 6) and between 6 and 12 months (IF6-12). Social inequalities were assessed using the slope index of inequality (SII) and concentration index (CIX). Trends in the prevalence of breastfeeding, IF and index of social inequality were analysed by a linear regression model with weighted least squares variance. Bolivia, Colombia, Dominican Republic, Guatemala, Haiti and Peru. 51·358 alive infants younger than 12 months. Five countries showed an increasing trend for EBF and BF6-12, four increased for IF < 6 and six for IF6-12. Simultaneous decrease in IF < 6 (Colombia: -0·3/year; Haiti: -0·02/year) and increase in EBF (Colombia: +2·0/year; Haiti: +1·9/year) were observed only in two countries. EBF prevalence was high in the lowest income quintiles in five countries, and IF prevalence was high in the highest income quintiles in all countries and over the decades. For BF6-12, a decrease in inequality (prevalence increased in the highest quintile) was observed in Guatemala (SII1995 = -0·42; SII2015 = -0·28) and the Dominican Republic (SII1996 = -0·54; SII2013 = -0·26). Guatemala was the only country showing a decrease in inequality for BF (SII = -0·005; CIX = -0·0035) and an increase for IF (SII = 0·022; CIX = 0·01). The inequality in BF and IF remained over time. However, inequality in IF < 6 has decreased because low-income infants have increased use and high-income infants have decreased.

Infant Formula Consumption Is Positively Correlated with Wealth, Within and Between Countries: A Multi-Country Study

ABSTRACTBackgroundIn contrast with the ample literature on within- and between-country inequalities in breastfeeding practices, there are no multi-country analyses of socioeconomic disparities in breastmilk substitute (BMS) consumption in low- and middle-income countries (LMICs).ObjectiveThis study aimed to investigate between- and within-country socioeconomic inequalities in breastfeeding and BMS consumption in LMICs.MethodsWe examined data from the Demographic Health Surveys and Multiple Indicator Cluster Surveys conducted in 90 LMICs since 2010 to calculate Pearson correlation coefficients between infant feeding indicators and per capita gross domestic product (GDP). Within-country inequalities in exclusive breastfeeding, intake of formula or other types of nonhuman milk (cow/goat) were studied for infants aged 0–5 mo, and for continued breastfeeding at ages 12–15 mo through graphical presentation of coverage wealth quintiles.ResultsBetween-country analyses showed that log GDP was inversely correlated with exclusive (r = −0.37, P < 0.001) and continued breastfeeding (r = −0.74, P < 0.0001), and was positively correlated with formula intake (r = 0.70, P < 0.0001). Continued breastfeeding was inversely correlated with formula (r = −0.79, P < 0.0001), and was less strongly correlated with the intake of other types of nonhuman milk (r = −0.40, P < 0.001). Within-country analyses showed that 69 out of 89 did not have significant disparities in exclusive breastfeeding. Continued breastfeeding was significantly higher in children belonging to the poorest 20% of households compared with the wealthiest 20% in 40 countries (by ∼30 percentage points on average), whereas formula feeding was more common in the wealthiest group in 59 countries.ConclusionsBMS intake is positively associated with GDP and negatively associated with continued breastfeeding in LMICs. In most countries, BMS intake is positively associated with family wealth, and will likely become more widespread as countries develop. Urgent action is needed to protect, promote, and support breastfeeding in all income groups and to reduce the intake of BMS, in light of the hazards associated with their use.

Gaps in Health and Wealth: The relationship between trends in income inequality and breastfeeding inequalities

ABSTRACT&#x0D; ObjectivesThe objective of this study was to identify whether breastfeeding inequalities have increased between 1984 and 2014 and to examine whether trends in income inequality are related to breastfeeding inequalities.&#x0D; MethodsWe used linkable administrative data from the Population Health Research Data Repository. Our sample included all infants born in Manitoba, 1984 to 2014. We used area-level income – derived from the Canadian Census – to stratify infants into income quintiles. Canadian Census income data were also used to quantify provincial level income inequality for each fiscal year in our study period. Data from the hospital discharge abstract database were used to classify infants according to whether or not they had initiated breastfeeding. We linked infant data to maternal data using the Manitoba health insurance registry to capture maternal characteristics – including the mother’s postal code of residence and her age at first birth. We used generalized linear models to calculate income quintile-specific breastfeeding rates for each fiscal year in our observation period for all of Manitoba. We also calculated age-adjusted breastfeeding rates to account for the changing age distribution in Manitoba mothers, over time. We measured breastfeeding inequities using the concentration index as well as the rate ratio and rate difference (comparing the breastfeeding rate between the highest and lowest income quintiles). We quantified income inequality using the Gini coefficient on income. Trend analyses and two-sided Z-tests tested for changes, over time. Time by income-quintile interactions tested whether breastfeeding rates were statistically significantly different, across socioeconomic groups.&#x0D; ResultsBreastfeeding rates increased from 1985 to 2014, from 72% to 81% (p&lt;0.01). The Gini coefficient increased from 0.16 to 0.21; a linear trend test of the Gini coefficient showed income inequality increased over the study period (p&lt;0.05). Rate differences, rate ratios, and the Concentration index showed that significant breastfeeding inequalities existed throughout the study period. Trend tests revealed that breastfeeding inequalities did not increase, over time.&#x0D; ConclusionsAggregate analyses may suggest overall improvement when inequality persists. Although there was improvement in breastfeeding initiation rates, children from lower socioeconomic status continue to lag behind their counterparts. Policy-focused health equity research needs to measure outcomes, overall, and inequity across time.

Breastfeeding in England: time trends 2005-2006 to 2012-2013 and inequalities by area profile.

Breastfeeding rates in England have risen steadily since the 1970s, but rates remain low and little is known about area-based trends. We report an ecological analysis of time trends in area breastfeeding rates in England using annual data on breastfeeding initiation (2005-2006 to 2012-2013) and any breastfeeding at 6-8 weeks (2008-2009 to 2012-2013) for 151 primary care trusts (PCTs). Overall, breastfeeding initiation rose from 65.5% in 2005-2006 to 72.4% in 2012-2013 (average annual absolute increase 0.9%). There was a statistically significantly higher (interaction P < 0.001) annual increase in initiation in PCTs in the most deprived (1.2%) compared with the least deprived tertile (0.7%), and in PCTs with low baseline breastfeeding initiation (2005-2006; 1.4%) compared with high baseline initiation (0.6%). Similar trends were observed when PCTs were stratified by the proportion of teenage mothers and maternal smoking, but not when stratified by ethnicity. Although breastfeeding prevalence at 6-8 weeks also increased significantly over the observed time period (41.2% in 2008-2009, 43.7% in 2012-2013; annual increase 0.7%), there was no difference in the average increase by deprivation profile, ethnicity, teenage mothers and maternal smoking. However, PCTs with low baseline prevalence in 2008-2009 saw a significantly larger annual increase (0.8%) compared with PCTs with high baseline prevalence (0.07%). In conclusion, breastfeeding initiation and prevalence have seen higher increases in areas with low initial breastfeeding, and for initiation, more disadvantaged areas. Although these results suggest that inequalities in breastfeeding have narrowed, rates have plateaued since 2010-2011. Sustained efforts are needed to address breastfeeding inequalities.

Have we left some behind? Trends in socio-economic inequalities in breastfeeding initiation: a population-based epidemiological surveillance study.

Breastfeeding is associated with improved health. Surveillance data show that breastfeeding initiation rates have increased; however, limited work has examined trends in socio-economic inequalities in initiation. The study's research question was whether socio-economic inequalities in breastfeeding initiation have changed over the past 20 years. This population-based study is a project within PATHS Equity for Children. Analyses used hospital discharge data for Manitoba mother-infant dyads with live births, 1988-2011 (n=316,027). Income quintiles were created, each with ~20% of dyads. Three-year, overall and by-quintile breastfeeding initiation rates were estimated for Manitoba and two hospitals. Age-adjusted rates were estimated for Manitoba. Rates were modelled using generalized linear models. Three measures, rate ratios (RRs), rate differences (RDs) and concentration indices, assessed inequality at each time point. We also compared concentration indices with Gini coefficients to assess breastfeeding inequality vis-à-vis income inequality. Trend analyses tested for changes over time. Manitoba and Hospital A initiation rates increased; Hospital B rates did not change. Significant inequalities existed in nearly every period, across all three measures: RRs, RDs and concentration indices. RRs and concentration indices suggested little to no change in inequality from 1988 to 2011. RDs for Manitoba (comparing initiation in the highest to lowest income quintiles) did not change significantly over time. RDs decreased for Hospital A, suggesting decreasing socio-economic inequalities in breastfeeding; RDs increased for Hospital B. Income inequality increased significantly in Manitoba during the study period. Overall breastfeeding initiation rates can improve while inequality persists or worsens.

Do population-based interventions widen or narrow socioeconomic inequalities? The case of breastfeeding promotion.

Despite numerous population-based randomized intervention trials, the impact of such interventions on socioeconomic inequalities has rarely been examined. We used data from a large cluster-randomized trial to assess the impact of a breastfeeding promotion intervention on socioeconomic inequalities in breastfeeding (exclusivity and duration) and in child cognitive ability at early school age. The Promotion of Breastfeeding Intervention Trial (PROBIT) randomized 31 Belarusian maternity hospitals and their affiliated polyclinics either to receive a breastfeeding promotion intervention modelled on the WHO/UNICEF Baby-Friendly Hospital Initiative or to continue the standard practices in effect at the time of randomization. We estimated and compared inequalities in discontinuation of exclusive breastfeeding before 3 months and of any breastfeeding before 12 months and in child verbal IQ at age 6.5 years, across maternal education strata between the two intervention arms. Socioeconomic inequalities in discontinuing exclusive breastfeeding before 3 months were negligible in the control group. However, graded inequalities by maternal education emerged in the intervention group {relative risk [RR] = 1.12 [95% confidence interval (CI): 1.04, 1.20] for partial university and RR = 1.20 [95% CI: 1.11, 1.31] for secondary education or less vs complete university; risk difference [RD] = 0.06 [95% CI: 0.03, 0.09] and 0.10 [95% CI: 0.06, 0.14], respectively}. For discontinuing any breastfeeding before 12 months, small socioeconomic gradients in the control group were widened in the intervention group (RR = 1.04 and 1.16, respectively, for mothers with secondary education or less). Despite these differential effects on breastfeeding, however, we observed a small, nonsignificant reduction in socioeconomic inequalities in child verbal IQ at age 6.5 years. A population-based intervention to promote breastfeeding slightly widened socioeconomic inequalities in breastfeeding but not those in child cognitive ability.

Factors associated with exclusive breast-feeding and breast-feeding in Norway

To identify factors associated with exclusive breast-feeding and breast-feeding during the first year of life among Norwegian infants. Data on breast-feeding practices were collected by a semi-quantitative FFQ. In 2006-2007 about 3000 infants were invited to participate in a population-based prospective cohort study in Norway. A total of 1490 mothers/infants participated at both 6 and 12 months of age. Exclusive breast-feeding at 4 months was associated with parental education, parity and geographical region, while exclusive breast-feeding at 5·5 months was associated only with maternal age. At both ages, a negative association with exclusive breast-feeding was observed for maternal smoking. Breast-feeding at 6 months was associated with parental education, maternal age and marital status. Breast-feeding at 12 months was associated with maternal education, maternal age and number of children. At both ages, negative associations with breast-feeding were observed for maternal smoking and descending birth weight. At 12 months, a negative association was also observed for having day care by other than the parents. Even though Norway has an extensive and positive breast-feeding tradition and a maternal leave system that supports the possibility to breast-feed, factors like maternal education, maternal age and maternal smoking are strongly associated with duration of exclusive breast-feeding and breast-feeding. Research to better understand the reasons for inequalities in breast-feeding is needed to facilitate the development of more effective breast-feeding promotion strategies. This again may improve compliance with recommendations and reduce inequalities in infant feeding practices.
