Are we doing enough? Improved breastfeeding practices at 14 weeks but challenges of non-initiation and early cessation of breastfeeding remain: findings of two consecutive cross-sectional surveys in KwaZulu-Natal, South Africa

Differences in Breastfeeding Duration by Maternal HIV Status: A Pooled Analysis of Nationally Representative Surveys in Sub-Saharan Africa

BACKGROUND

Breastfeeding improves child survival but is a source of mother-to-child HIV transmission among women with unsuppressed HIV infection. Estimated HIV incidence in children is sensitive to breastfeeding duration among mothers living with HIV (MLHIV). Breastfeeding duration may vary according to maternal HIV status.

SETTING

Sub-Saharan Africa.

METHODS

We analyzed pooled data from nationally representative household surveys conducted during 2003-2019 that included HIV testing and elicited breastfeeding practices. We fitted survival models of breastfeeding duration by country, year, and maternal HIV status for 4 sub-Saharan African regions (Eastern, Central, Southern, and Western).

RESULTS

Data were obtained from 65 surveys in 31 countries. In 2010, breastfeeding in the first month of life ("initial breastfeeding") among MLHIV ranged from 69.1% (95% credible interval: 68-79.9) in Southern Africa to 93.4% (92.7-98.0) in Western Africa. Median breastfeeding duration among MLHIV was the shortest in Southern Africa at 15.6 (14.2-16.3) months and the longest in Eastern Africa at 22.0 (21.7-22.5) months. By comparison, HIV-negative mothers were more likely to breastfeed initially (91.0%-98.7% across regions) and for longer duration (median 18.3-24.6 months across regions). Initial breastfeeding and median breastfeeding duration decreased during 2005-2015 in most regions and did not increase in any region regardless of maternal HIV status.

CONCLUSIONS

MLHIV in sub-Saharan Africa are less likely to breastfeed initially and stop breastfeeding sooner than HIV-negative mothers. Since 2020, UNAIDS-supported HIV estimates have accounted for this shorter breastfeeding exposure among HIV-exposed children. MLHIV need support to enable optimal breastfeeding practices and to adhere to antiretroviral therapy for HIV treatment and prevention of postnatal mother-to-child transmission.

Financial and Food Insecurity are Primary Challenges to Breastfeeding for Women Living with HIV in Western Kenya: A Longitudinal Qualitative Investigation

Exclusive breastfeeding for the first 6 months and continued breastfeeding for 24 months or longer is recommended for all mothers world-wide, including women living with HIV (WLWH). Given evidence of suboptimal infant feeding and the need to understand context specific barriers, we explored experiences of perinatal WLWH in Kisumu, Kenya. We applied a longitudinal qualitative approach (4 in-depth interviews) with 30 women from pregnancy to 14-18 months postpartum. Cross-sectional profiling led to a narrative description of infant feeding across time. The majority of women breastfed exclusively for 6 months and weaned by 18 months. Severe financial and food insecurity were primary challenges as women worked through when/how to breastfeed or stop breastfeeding in the setting of multiple competing priorities/pressures across time. Financial and food support and increased support for breastfeeding beyond 18 months have the potential to reduce women's stress and uncertainty associated with infant feeding as well as optimize infant health and nutrition in this setting.

Relationship between pre-pregnancy maternal body mass index and infant weight trajectories in HIV-exposed and HIV-unexposed infants

BACKGROUND

Maternal HIV and antiretroviral therapy (ART) exposure in utero may influence infant weight, but the contribution of maternal y body mass index (BMI) to early life overweight and obesity is not clear.

OBJECTIVE

To estimate associations between maternal BMI at entry to antenatal care (ANC) and infant weight through approximately 1 year of age and to evaluate whether associations were modified by maternal HIV status, maternal HIV and viral load, breastfeeding intensity through 6 months or timing of entry into ANC.

METHODS

We followed HIV-uninfected and -infected pregnant women initiating efavirenz-based ART from first antenatal visit through 12 months postpartum. Infant weight was assessed via World Health Organization BMI and weight-for-length z-scores (WLZ) at 6 weeks, 3, 6, 9 and 12 months. We used multivariable linear mixed-effects models to estimate associations between maternal BMI and infant z-scores over time.

RESULTS

In 861 HIV-uninfected infants (454 HIV-exposed; 407 HIV-unexposed), nearly 20% of infants were overweight or obese by 12 months of age, regardless of HIV exposure status. In multivariable analyses, increasing maternal BMI category was positively associated with higher infant BMIZ and WLZ scores between 6 weeks and 12 months of age and did not differ by HIV exposure status. However, HIV-exposed infants had slightly lower BMIZ and WLZ trajectories through 12 months of age, compared with HIV-unexposed infants across all maternal BMI categories. Differences in BMIZ and WLZ scores by HIV exposure were not explained by timing of entry into ANC or maternal viral load pre-ART initiation, but z-scores were slightly higher for HIV-exposed infants who were predominantly or exclusively versus partially breastfed.

CONCLUSIONS

These findings suggest maternal BMI influences early infant weight gain, regardless of infant HIV exposure status. Intervention to reduce maternal BMI may help to address growing concerns about obesity among HIV-uninfected children.

Adherence to Optimal Breastfeeding Practices Among HIV-Positive Mothers in Kilimanjaro, Tanzania

Purpose

We sought to assess how HIV-positive mothers enrolled in the PMTCT program adhere to breastfeeding recommendations concerning early initiation of breastfeeding (EIBF), ie, within one hour of birth, pre-lacteal feeds, exclusive breastfeeding until six months (EBF), and continued breastfeeding to one year of age. This study was designed to assess the practices in response to changing recommendations for breastfeeding in HIV, which have differed drastically over the years.

Patients and Methods

We recruited 524 mother-child pairs from 37 PMTCT clinics across Kilimanjaro, Tanzania. The 5 clinics with the highest patient load in each of the 7 districts of Kilimanjaro were chosen, plus the zonal and municipal referral hospitals. The children were below two years of age and currently in the PMTCT program. We administered a questionnaire to assess the mother's practices in feeding the child. We used multiple logistic regression models to determine factors associated with EIBF, EBF, and continued breastfeeding.

Results

EIBF was achieved for 73.1% of babies. Cesarean delivery, low birth weight, and partner disclosure of HIV status were significant risk factors for not achieving EIBF. About 19% of children did not breastfeed exclusively. Of the 247 children ≥12 months old, 43.3% had stopped breastfeeding before 12 months. Counseling on ARV, having had >2 pregnancies while HIV-positive and EBF were associated with breastfeeding until 12 months old. Using ART for more than two years decreased the odds of EBF and continued breastfeeding to 12 months of age.

Conclusion

Adherence to breastfeeding recommendations for HIV-positive women is suboptimal, particularly in aspects of recent changes in recommendations such as continuing breastfeeding for one year. There is a missed opportunity for interventions such as counseling, which has shown to favor adherence. Health education and counseling are needed for providers and mothers to keep them abreast with the frequently changing recommendations.

Why do first-time mothers not intend to breastfeed? --A qualitative exploratory study on the decision-making of non-initiation in Jingzhou, China

Background

Although breastfeeding is one of the top priorities for public health in China, the rate of breastfeeding is still low and a large number of women do not initiate breastfeeding due to various reasons. Hence, this study aimed to understand the decision-making of non-initiation and reveal the underlying reasons in order to protect, support, and promote breastfeeding.

Methods

In-depth, exploratory interviews were carried out with 13 new mothers who did not initiate breastfeeding. The collected data were analyzed by inductive content analysis.

Results

Although mothers generally understood the protective effects of breastfeeding, they believed that formula milk is a good alternative to human milk and even better in some aspects. Five core themes related to non-initiation decision-making emerged: (1) expected breastfeeding stress; (2) maladjustment to the maternal role; (3) concerns about physiological issues; (4) the lack of knowledge about the risks of artificial feeding; (5) belief that it is better not to initiate than to interrupt.

Conclusions

The environment for mothers to breastfeed in China is not supportive enough, and the medical staff and families should be held responsible for the non-initiation of breastfeeding. More professionals are needed to support mothers to solve their problems and breastfeeding education should be further expanded.

Infant feeding, growth monitoring and the double burden of malnutrition among children aged 6 months and their mothers in KwaZulu‐Natal, South Africa

South Africa has a documented high prevalence of stunting and increasing obesity in children as well as obesity in adults. The double burden of malnutrition, which can be on an individual‐, household‐ or population level, has implications for both health and the economic development of a community and country. This paper describes a large‐scale survey (N = 774) of infant feeding, growth monitoring and anthropometry among mother and child pairs aged 6 months of age in KwaZulu‐Natal (KZN), South Africa, conducted between January and August 2017. Among children, a large increase in the prevalence of stunting and obesity was seen between birth and 6 months of age increasing from 9.3% to 21.7% and 4.0% to 21.0%, respectively. 32.1% of the mothers were overweight [body mass index (BMI): 25.0–29.9] and 28.4% had obesity grade 1 (BMI: 30–<40). Although most mothers (93%; 563/605) initiated breastfeeding, the introduction of other foods started early with 17.6% (56/319) of the mothers having started giving other fluids or food to their child within the first month. At 6 months 70.6% (427/605) children were still breastfed and 23.5% were exclusively breastfed. In addition, we found that length measurements were done less frequently than weight measurements between birth and 6 months, on average 2.2 (SD: 1.3) versus 5.8 (SD: 1.5) times. Moreover, there is a need for improvement of health worker training and understanding regarding anthropometric measurements when assessing malnutrition in children in the clinics. Early detection and improved infant feeding practices are key in preventing both stunting and obesity in children.

The double burden of malnutrition is severe in KwaZulu‐Natal with high rates of maternal obesity and increasing prevalence of stunting and obesity among infants in the first 6 months of life.

Breastfeeding and complementary feeding practices are suboptimal and additional support for breastfeeding is required in the post‐natal period and in the workplace to address breastfeeding challenges.

Growth monitoring is inadequate in health facilities leading to many lost opportunities for early identification of malnutrition. Hence, anthropometric practices and interpretation of findings need to be strengthened.

Father involvement, maternal depression and child nutritional outcomes in Soweto, South Africa

Father involvement in South Africa is low, despite evidence that it can improve maternal and child health and wellbeing. Within a larger randomised controlled trial, we assessed whether father involvement during and after pregnancy increased birth weight and exclusive breastfeeding through improved maternal mental health. At 6-week postnatal, mothers completed questionnaires on birth, feeding practices, social support, father involvement and postnatal depression. Father involvement during pregnancy was measured by their attendance at antenatal care and the study intervention, whereas postnatal involvement was measured by attendance at antenatal care and type of paternal support provided. Structural equation modelling was used to identify associations between father involvement, maternal depression, low birth weight and exclusive breastfeeding. Among the 212 mother-baby pairs, father involvement was very low with only 43%, 33% and 1% of partners attending early ultrasound, antenatal care and the birth of the child, respectively. Twenty-nine percent of the mothers showed signs of depression during pregnancy, compared with 7% after birth. Eighteen percent of the infants were born low birth weight, and 57% of mothers reported exclusively breastfeeding at 6 weeks. Father involvement was directly associated with postnatal depression, but it did not directly or indirectly impact exclusive breastfeeding or low birth weight. We conclude that postnatal father involvement can improve postnatal maternal depression and that men would benefit from specific guidance on how they can support mothers during and after pregnancy.

Growth patterns and clinical outcomes in association with breastfeeding duration in HIV exposed and unexposed infants: a cohort study in KwaZulu Natal, South Africa

Background

Exclusive breastfeeding for 6 months and breastfeeding with complementary feeds until 12 months for HIV exposed and uninfected (HEU) infants or 24 months for HIV unexposed (HU) infants is the current World Health Organisation (WHO) recommendation for low and middle income countries (LMICs) to improve clinical outcomes and growth trajectories in infants. In a post-hoc evaluation of HEU and HU cohorts, we examine growth patterns and clinical outcomes in the first 9 months of infancy in association with breastfeeding duration.

Methods

Two cohorts of infants, HEU and HU from a low-socioeconomic township in South Africa, were evaluated from birth until 9 months of age. Clinical, anthropometric and infant feeding data were analysed. Standard descriptive statistics and regression analysis were performed to determine the effect of HIV exposure and breastfeeding duration on growth and clinical outcomes.

Results

Included in this secondary analysis were 123 HEU and 157 HU infants breastfed for a median of 26 and 14 weeks respectively. Median WLZ score was significantly (p < 0.001) lower in HEU than HU infants at 3, 6 and 9 months (− 0.19 vs 2.09; − 0.81 vs 0.28; 0.05 vs 0.97 respectively). The median LAZ score was significantly lower among HU infants at 3 and 6 months (− 1.63 vs 0.91, p < 0.001; − 0.37 vs 0.51, p < 0.01) and a significantly higher proportion of HU was classified as stunted (LAZ < -2SD) at 3 and 6 months (3.9% vs 44.9%, p < 0.001; 4.8% vs 20.9%, p < 0.001 respectively) independent of breastfeeding duration. A higher proportion of HEU infants experienced one or more episodes of skin rash (44.5% vs 12.8%) and upper respiratory tract infection (URTI) (30.1% vs 10.9%) (p < 0.0001). In a multivariable analysis, the odds of occurrence of wasting, skin rash, URTI or any clinical adverse event in HEU infants were 2.86, 7.06, 3.01 and 8.89 times higher than HU infants after adjusting for breastfeeding duration.

Conclusion

Our study has generated additional evidence that HEU infants are at substantial risk of infectious morbidity and decreased growth trajectories however we have further demonstrated that these adverse outcomes were independent of breastfeeding duration.

Formal maternal employment is associated with lower odds of exclusive breastfeeding by 14 weeks postpartum: a cross-sectional survey in Naivasha, Kenya

BACKGROUND

In many low- and middle-income countries, improvements in exclusive breastfeeding (EBF) have stalled, delaying reductions in child mortality. Maternal employment is a potential barrier to EBF.

OBJECTIVES

We evaluated associations between maternal employment and breastfeeding (BF) status. We compared formally and non-formally employed mothers in Naivasha, Kenya, where commercial floriculture and hospitality industries employ many women.

METHODS

We conducted a cross-sectional survey among mothers (n = 1186) from September 2018 to October 2019 at 4 postpartum time points: at hospital discharge (n = 296) and at 6 wk (n = 298), 14 wk (n = 295), and 36 wk (to estimate BF at 24 wk; n = 297) postpartum. Mothers reported their BF status and reasons for EBF cessation. We used multivariable logistic regression models to test the association between formal maternal employment and 3 outcomes: early BF initiation (within 1 h of birth), EBF at each time point, and continued BF at 9 mo. Models were informed by a directed acyclic graph: a causal diagram used to characterize the relationship among variables that influence the independent (employment) and dependent (BF status) variables.

RESULTS

EBF did not differ by employment status at hospital discharge or at 6 wk postpartum. However, formally employed mothers were less likely than those not formally employed to report EBF at 14 wk (59.0% compared with 95.4%, respectively; AOR: 0.19; 95% CI: 0.10, 0.34) and at 24 wk (19.0% compared with 49.6%, respectively; AOR: 0.25; 95% CI: 0.14, 0.44). The prevalence of continued BF at 36 wk did not differ by group (98.1% for formally employed compared with 98.5% for non-formally employed women; AOR: 0.80; 95% CI: 0.10, 6.08). The primary reasons reported for early EBF cessation were returning to work (46.5%), introducing other foods based on the child's age (33.5%), or perceived milk insufficiency (13.7%).

CONCLUSIONS

As more women engage in formal employment in low- and middle-income countries, additional supports to help prolong the period of EBF may be beneficial for formally employed mothers and their children.
