Infant feeding knowledge and practice vary by maternal HIV status: a nested cohort study in rural South Africa



We investigate whether correct infant feeding knowledge and practice differ by maternal HIV status in an era of evolving clinical guidelines in rural South Africa.


This cohort study was nested within the MONARCH stepped-wedge cluster-randomised controlled trial ( NCT02626351) which tested the impact of continuous quality improvement on antenatal care quality at seven primary care clinics in KwaZulu-Natal, from July 2015 to January 2017. Women aged ≥18 years at delivery were followed up to 6 weeks postpartum. Clinical data were sourced from routine medical records at delivery. Structured interviews at early postnatal visits and the 6-week postnatal immunisation visit provided data on infant feeding knowledge and feeding practices respectively. We measured the relationship between maternal HIV status and (i) correct infant feeding knowledge at the early postnatal visit; and (ii) infant feeding practice at 6 weeks, using Poisson and multinomial regression models, respectively.


We analysed data from 1693 women with early postnatal and 471 with 6-week postnatal interviews. HIV prevalence was 47% (95% confidence interval [CI] 42, 52%). Women living with HIV were more knowledgeable than women not living with HIV on correct infant feeding recommendations (adjusted risk ratio, aRR, 1.08, p <  0.001). More women living with HIV (33%; 95% CI 26, 41%) were not breastfeeding than women not living with HIV (15%; 95% CI 11, 21%). However, among women who were currently breastfeeding their infants, fewer women living with HIV (5%; 95% CI 2, 9%) mixed fed their babies than women not living with HIV (21%; 95% CI 14, 32%). In adjusted analyses, women living with HIV were more likely to avoid breastfeeding (adjusted relative risk ratio, aRRR, 2.78, p <  0.001) and less likely to mixed feed (aRRR 0.22, p <  0.001) than women not living with HIV.


Many mothers in rural South Africa still do not practice exclusive breastfeeding. Women living with HIV were more knowledgeable but had lower overall uptake of breastfeeding, compared with women not living with HIV. Women living with HIV were also more likely to practice exclusive breastfeeding over mixed feeding if currently breastfeeding. Improved approaches are needed to increase awareness of correct infant feeding and exclusive breastfeeding uptake.


Exclusively breastfeeding infants for the first 6 months of life can be life-saving, have long-term health benefits [1,2,3,4], and is aligned with sustainable development goals (SDGs) [5]. Yet a potential barrier to uptake of breastfeeding in HIV-endemic settings is risk of mother-to-child transmission of HIV (MTCT) which is correlated with maternal viral load [6, 7]. Effective antiretroviral therapy (ART) during pregnancy and breastfeeding minimises MTCT [7]. Exclusive breastfeeding also lowers MTCT risk compared with mixed feeding (breastmilk with other foods or fluids) even with untreated maternal HIV [4, 8]. An important caveat is HIV reservoirs in latent and active CD4+ T cells in breastmilk even among women on suppressive ART [9]. The benefits of exclusive breastfeeding in resource-poor settings outweigh any risks (including concerns of micronutrient deficiency without supplementary feeds after 4 months of age) [10], supporting recommendations of exclusive breastfeeding for all infants until 6 months of age regardless of maternal HIV status [11, 12].

Although the rapid evolution of clinical guidelines may challenge their real-time implementation, infant feeding guidelines and elimination of mother-to-child transmission of HIV (eMTCT) guidelines must be applied concurrently for maximal impact, particularly in HIV-endemic settings. South Africa, the highest HIV burden country in the world, has further changed infant feeding and ART guidelines since 2015 alongside major efforts to improve exclusive breastfeeding (6 months for all women) since 2011 [13,14,15]. These changes included revising the total breastfeeding duration to 24 months for all women regardless of HIV status aligned with WHO guidelines [16], CD4 eligibility expansions for ART — Option B+ for pregnant and breastfeeding women from January 2015 [17], and Universal Test and Treat for all people living with HIV from September 2016 [18] — and more frequent HIV viral load monitoring [17, 18].

Within the context of these new guidelines we anticipate more postpartum women to initiate and sustain exclusive breastfeeding in South Africa, because they may be more confident in suppressive ART; be aware of how maternal viral load influences HIV transmission, and be aware of the dangers of mixed feeding and benefits of exclusive breastfeeding. However, despite substantial improvements in exclusive breastfeeding initiation [19,20,21,22], early cessation of exclusive breastfeeding remains a problem [22,23,24,25].

The antenatal period is a crucial phase during which women engaging with healthcare services may become aware of their HIV status and receive critical information on HIV care and infant feeding. Women’s knowledge of infant feeding recommendations, knowledge of HIV, and actual feeding practices therefore reflect quality of healthcare services. We tested whether a continuous quality improvement (CQI) intervention (MONARCH, NCT02626351) could improve antenatal HIV services in public sector primary care clinics [26, 27]. The pre-registered primary endpoints were HIV viral load monitoring among pregnant women living with HIV and repeat HIV testing among pregnant women not living with HIV; the primary findings are reported elsewhere: briefly, CQI improved viral load monitoring but not repeat HIV testing [27].

The aims of this paper are to examine, among women recruited to the MONARCH trial (1) whether knowledge of infant feeding recommendations differs by maternal HIV status; and (2) whether infant feeding practice differs by maternal HIV status.


Study design

The CQI intervention targeted health workers providing antenatal services at seven participating primary care clinics in northern KwaZulu-Natal, located within and adjoining the Africa Health Research Institute (AHRI) population intervention platform surveillance area (PIPSA). The first six of these seven primary care clinics are all of the clinics located within the AHRI PIPSA geographic bounds, which formed the contiguous geographically designed study community for this study. The seventh clinic, located in the market town of Mtubatuba, was located outside the AHRI PIPSA geographic bounds. We included this clinic in our study, because it is the one primary clinic that people living in the AHRI PIPSA community frequently attend [26]. Details of the MONARCH stepped-wedge cluster-randomised controlled trial are reported elsewhere [26].

The present cohort study was nested within the parent trial. Eligible women were followed from delivery up to 6 weeks postpartum, between July 2015 and January 2017. Thus, the same version of guidelines on duration of exclusive breastfeeding (6 months for all women) and ART eligibility for pregnant and breastfeeding women (removal of CD4 count criteria, Option B+) applied to all women enrolled in this study.


Women were aged ≥18 years at delivery and recruited at three time points independent of previous or future recruitment: delivery, the 3–6 day postnatal visit, and the 6-week postnatal immunisation visit [26]. Women who were recruited at more than one time point were linked within the study database. Women were recruited at delivery if they were resident within the AHRI population surveillance area during pregnancy or attended one of the seven study clinics during pregnancy [26]. At postnatal visits, women who attended a study clinic were recruited regardless of their antenatal clinic or area of residency.


The main exposure of interest was maternal HIV status at delivery, as documented in the antenatal medical record.


We considered the following two endpoints: (1) correct knowledge of infant feeding recommendations at an early postnatal visit (delivery or 3–6 days postpartum); and (2) self-reported uptake of feeding modalities in relation to exclusive breastfeeding at 6 weeks postpartum (see Table 1 for definitions). We also describe knowledge of HIV treatment and transmission as an exploratory analysis, by maternal HIV status.

Table 1 Study endpoint definitions

Data sources

Clinical data including HIV status were sourced from antenatal medical records. Structured interviews of consenting women conducted at delivery, the 3–6 day postnatal visit and the 6-week postnatal visit were sourced for demographic data and the endpoints listed above. The delivery and 3–6 day postnatal interviews were identical and included a theme on knowledge of infant feeding (Table S1), whereas the 6-week postnatal interview covered knowledge of HIV treatment and transmission, and self-reported practices of infant feeding (Table S1) [26]. We selected the 6-week interview for HIV treatment and transmission knowledge questions for the following reasons: (i) we were concerned women may find such questions too stressful to handle shortly after giving birth, and (ii) the 6-week postnatal visit was the next scheduled routine clinic visit (aligned with infant immunisation) following the 3–6 day postnatal visit. Given our recruitment method, some women were interviewed at delivery and the 3–6 day postnatal visit, whereas others were interviewed at only one of these early postnatal visits.

Participants were included in the analysis for endpoint 1 (feeding knowledge) if they had (i) a medical record available; and (ii) a delivery or 3–6 day (early postnatal) interview available. Where both delivery and 3–6 day interviews were available, the delivery interview was analysed as it was the earliest opportunity to measure maternal feeding knowledge. Participants were included in the analysis for endpoint 2 (feeding practice) if they had (i) a medical record available; and (ii) a delivery or 3–6 day interview available; and (iii) a 6-week postnatal interview available. Knowledge of HIV treatment and transmission was analysed only among women included for endpoint 2.

Statistical analyses

We used Poisson regression to determine the association between HIV status and correct knowledge of infant feeding, because our knowledge outcome was a count. The regression model generated risk ratios (RR). We then used a multinomial regression model [28] to determine the association between HIV status and three unordered categories of infant feeding (exclusive breastfeeding, mixed feeding, not currently breastfeeding). Not currently breastfeeding and mixed feeding were each compared against the base category of exclusive breastfeeding. Coefficients were generated for the effect of each independent variable (including HIV status) on each feeding category relative to the base category of exclusive breastfeeding (relative risk ratios, RRR).

All ‘basic’ models included adjustments for maternal age and education status. Models for feeding practice also included infant feeding knowledge. Adjusted models were complete case analyses with covariates for parity, relationship status, employment status, household assets, CQI exposure, and calendar time. We used household assets as a proxy for household income given the large number of missing responses to the latter. We also separately explored knowledge of HIV treatment and transmission (from 6-week postnatal interviews) to support our interpretation of feeding practices. We clustered standard errors by first attended antenatal clinic (i.e., the seven study clinics and a category for “other” clinics). Based on our eligibility criteria for recruitment at delivery, not all women attended a study clinic at their first antenatal visit. The first antenatal clinic was selected as that was the first opportunity for influencing the reported outcomes.

Sensitivity analyses: in the adjusted models for infant feeding knowledge (early postnatal interviews) and infant feeding practices (6-week postnatal interviews) we substituted household income for household assets to examine the robustness of our main findings.

Statistical significance was defined at the α = 0.05 level. Stata version 15.0 (StataCorp. 2017. Stata Statistical Software: Release 15) was used for all analyses.


Of 3147 participants in the parent trial, 2498 had a medical record available. Of these, 1693 women (68%) completed a delivery and/or 3–6 day (early postnatal) interview; 516/1693 completed both delivery and 3–6 day interviews; 471/1693 women (28%) completed a 6-week postnatal interview. Participant characteristics at the early postnatal visit of those with and without a 6-week postnatal interview were similar (Table S2). Most women (86%) attended a study clinic for their first antenatal care (ANC) visit.

Median age was 25 years (interquartile range [IQR], 21–30). Median gestation at first ANC visit was 19 weeks (IQR 15–24 weeks). Most women were unemployed and were not living with their partner (Table 2). Women living with HIV were less educated, had less household wealth and more children than women not living with HIV; however, more women living with HIV were employed than women not living with HIV (Table 2). HIV prevalence at delivery was 47% (95% CI 42, 52%). Of women living with HIV, 93% had at least one documented ART prescription during pregnancy and 56% had at least one viral load measured during pregnancy. Of viral loads performed 53% had a documented result, 83% of which were suppressed < 200 copies/mL.

HIV status and infant feeding knowledge (early postnatal interviews)

Most women living with HIV and women not living with HIV responded correctly to infant feeding knowledge questions (Table 3). Women living with HIV were more likely to be knowledgeable on infant feeding recommendations in basic (RR 1.09; 95% CI 1.07, 1.11) and adjusted (aRR 1.08; 95% CI 1.06, 1.09) regression models which included a covariate for parity (Table S3). This may be due to differences in awareness of the definition of exclusive breastfeeding and feeding recommendations for HIV-exposed infants (Table 3).

Table 3 Descriptive outcomes by HIV status: correct knowledge of infant feeding and infant feeding practices

Our findings remained robust to substituting household income for household assets in the adjusted model (aRR 1.08; 95% CI 1.06, 1.10), with a similar range of uncertainty (Table S3).

Uptake of any breastfeeding

Overall 351/467 (75%) women were breastfeeding (including exclusive breastfeeding and mixed feeding). Fewer women living with HIV (66%) were breastfeeding at 6 weeks compared with women not living with HIV (84%), Table 3.

Uptake of exclusive breastfeeding

Although similar proportions of all women living with HIV (63%) and women not living with HIV (66%) respectively practised exclusive breastfeeding, there were key differences by HIV status in mixed feeding and not currently breastfeeding (Table 3). In regression models relative to the baseline feeding category exclusive breastfeeding, women living with HIV (versus women not living with HIV) were more likely not to breastfeed in basic (RRR 2.62; 95% CI 1.71, 4.02) and adjusted (aRRR 2.78; 95% CI 1.78, 4.34) models. Moreover, women living with HIV were less likely to mixed feed their babies in basic (RRR 0.22; 95% CI 0.12, 0.41) and adjusted (aRRR 0.22; 95% CI 0.11, 0.43) models, see Fig. 1 and Table S3.

Graphs depict outputs from unadjusted and adjusted multinomial regression models comparing (i) not breastfeeding vs exclusive breastfeeding, and (ii) mixed feeding vs exclusive breastfeeding. The unadjusted (basic) model contains a priori covariates for maternal age, education and knowledge. The adjusted model contains additional covariates for parity, employment, relationship status, household assets, CQI exposure, and time. Both unadjusted and adjusted models account for clinic-level clustering of outcomes. CQI, continuous quality improvement; WLHIV, women living with HIV; WNLHIV, women not living with HIV

Our findings remained robust when we substituted household income for household assets in the adjusted model, albeit with a wider range of uncertainty: relative to the baseline feeding category exclusive breastfeeding, women living with HIV (versus women not living with HIV) were more likely not to breastfeed (aRRR 3.90; 95% CI 2.44, 6.24) and were less likely to mixed feed their babies (aRRR 0.26; 95% CI 0.11, 0.61), see Table S3.

Knowledge of HIV treatment and transmission (6-week postnatal interviews)

Most women living with HIV and women not living with HIV responded correctly to questions on HIV testing, the role of ART and the role of CD4 count. More women living with HIV responded correctly than did women not living with HIV to each question (Fig. 2). However, knowledge of viral load and its role in HIV transmission was poor, even among women living with HIV.

Other factors associated with feeding practice

Unemployed women were more likely to exclusively breastfeed than not breastfeed (aRRR for not breastfeeding vs exclusive breastfeeding 0.39; 95% CI 0.20, 0.76). Although infant feeding knowledge was associated with lower likelihood of mixed feeding vs exclusive breastfeeding in the basic model (RRR 0.50; 95% CI 0.30, 0.84), the effect size did not persist in the adjusted model and is of unclear significance. HIV treatment and transmission knowledge scores and other factors were not associated with infant feeding modality at commonly used benchmarks of statistical significance.

Reasons for infant feeding choice

Of 112 participants not currently breastfeeding, 43 provided reasons: lack of milk (26%), return to work (21%), and being too busy (12%); of the 28 women living with HIV, 21% cited HIV as a reason for not breastfeeding. Among 49 participants who were mixed feeding, reasons included lack of milk (47%), crying baby (33%), and return to work (4%).


Using data on 1693 women enrolled in our parent trial in rural South Africa, we demonstrate differences in knowledge of correct infant feeding recommendations, and self-reported infant feeding practices between mothers with and without HIV. Although women living with HIV were more knowledgeable on infant feeding recommendations, they were less likely to breastfeed than women not living with HIV. Conversely, among those currently breastfeeding, women living with HIV were more likely to exclusively breastfeed than mixed feed. Knowledge of the meaning and role of viral load suppression was poor, even among women living with HIV, and not associated with feeding practice. Our findings are important for health policy as future areas for targeted interventions.

Overall exclusive breastfeeding uptake in our study was similar to other studies from South Africa and elsewhere [19, 20, 23, 25, 29]. Our study mirrors two other studies on differences in exclusive breastfeeding uptake among women living with HIV compared with women not living with HIV in the Option B+ era [19, 20], despite being nested within a trial specifically targeting antenatal care quality for all women.

We postulate several reasons for these differences in infant feeding knowledge and practice. First, factors at health service level may have resulted in different delivery of feeding messages and support to women living with HIV compared with women not living with HIV. Importantly, there was no evidence of a CQI spillover effect from the main trial, and this is potentially attributable to insufficient time to improve infant feeding during the CQI intervention (due to time constraints of the study design and emphasis on primary endpoints). There may have been more opportunities for health workers to engage with women living with HIV (e.g. due to higher frequency of clinical consultations for HIV), or women not living with HIV may have paid less attention to messages due to less perceived relevance to themselves. Gaps in health worker understanding of the scientific rationale for exclusive breastfeeding among women living with HIV and women not living with HIV [30, 31], or inadequate breastfeeding support by health workers may have also contributed [32]. Consistent messaging and support to all women, regardless of their HIV status, are critical in an HIV hyperendemic setting such as this [33] where HIV seroconversion during the breastfeeding period is a real concern and risk of MTCT is high [34].

Second, there may be other individual- or community-level factors that transcend availability of correct information, although correct knowledge of infant feeding guidelines [19, 35,36,37] and quality of health worker messaging [19, 20, 23, 25, 38] influence individual feeding choice and duration. One factor is employment status [14, 20, 22, 39], especially as financial pressures may compel return to work shortly after birth without paid maternity leave [14, 40] and women may prefer replacement feeds over expressed breastmilk when returning to work or study [38]. Another is a limited support network for breastfeeding: most women in our study were not living with their partner, and poverty and unemployment may hinder marriage given traditional customs of bridewealth [41]. Among those who initiate breastfeeding, factors that may contribute to early cessation include cultural beliefs, stigma, HIV status disclosure, maternal mental health concerns, lack of a supportive workplace, and lack of paid maternity leave [14, 19, 21, 22, 29, 40]. Family pressures may also override women’s feeding choice [25, 30, 38, 39].

Finally, even among women living with HIV, awareness of the role of HIV viral load in treatment response and transmission was low. This knowledge gap — despite established South African national guidelines recommending HIV viral load monitoring for individuals on ART [42], and routinely available viral load monitoring at all facilities in the area – may be attributable to underutilisation of viral load monitoring as identified in our parent trial [27]. Whilst we expect better HIV treatment and transmission knowledge among women living with HIV, both groups of women were knowledgeable about HIV testing, the role of ART, and what a CD4 count means, indicating wide reach of general HIV treatment messages in this HIV hyperendemic community. Although HIV treatment and transmission knowledge were not associated with feeding practice, correct information on viral load is critical for ART adherence and reassurance on the safety of exclusive breastfeeding.

We add to the emerging evidence of infant feeding knowledge and practice in South African primary healthcare services after establishment of landmark HIV treatment guidelines [17, 18]. The limited maternal awareness of HIV viral load highlights the need for updating public health messages alongside rigorously implementing ART guidelines at health facilities. Methodological strengths of our study include maternal HIV status sourced directly from clinical records, detailed sociodemographic data from interviews, and a stringent definition of exclusive breastfeeding. By measuring feeding knowledge prior to feeding practice, we reduced knowledge recall bias.

There are some limitations to our study. First, our follow-up period was limited to 6 weeks and the total breastfeeding duration in our cohort is unknown. Second, social desirability biases may have influenced self-reported feeding practices. Third, the relatively small sample size of 6-week postnatal interviews may have reduced statistical power. Fourth, only a small subset of participants provided reasons for their feeding practices, and those results must be interpreted with caution.

Areas for further research include integrating maternal and child services, and interdisciplinary interventions to sustain exclusive breastfeeding. Longitudinal studies in the “treat all” era, on actual infant feeding practice up to 2 years postpartum concurrently with regular postpartum HIV testing for women not living with HIV, viral load monitoring for women living with HIV, and early diagnosis of HIV-exposed infants are needed.


We found differences in infant feeding knowledge and practice among women living with HIV and women not living with HIV. We also found poor knowledge of the role of HIV viral load in monitoring treatment response and transmission. These findings may be due to differences in quality of health worker messages on feeding and low utilisation of HIV viral load in clinical practice.

A multifactorial approach is encouraged. These include enhanced health worker training and supervision on adherence to infant feeding and HIV treatment guidelines, education interventions targeting the wider community including family members, and work environments conducive to breastfeeding. We recommend routine programme evaluation indicators on infant feeding modality up to 2 years postpartum. Areas for future research include longitudinal studies on MTCT during the entire breastfeeding period.
