Current knowledge and future research on infant feeding in the context of HIV: basic, clinical, behavioral, and programmatic perspectives

Perspectives of healthcare workers on the acceptability of donor human milk banking in Southwest Nigeria

BACKGROUND

The World Health Organization prioritizes Mother's Own Milk (MOM) or donor human milk (DHM) when MOM is unavailable or insufficient. It is also important for healthcare workers (HCWs) to provide adequate support, information, and education to mothers to help improve their milk production and breastfeeding experience. DHM is scarce in developing countries, prompting a need for understanding health workers' perspectives.

METHODS

This cross-sectional study, conducted in 2021 in Ekiti State, Nigeria, examined the knowledge and attitudes of HCWs regarding human milk banking. A sample of 321 participants from government-owned hospitals completed a self-administered questionnaire.

RESULTS

Of the 321 participants (84.7% response rate), the majority were females (69.2%), aged 30-39 (32.1%), Christian (91.9%), and employed in tertiary hospitals (91.9%). About 65% of the HCWs believe that HMB is a safe practice and 42% believe that the DHM has the same quantity of immunological factors as fresh human milk. While 80.4% displayed good DHM knowledge, attitudes varied. The HCWs profession influenced their attitudes and a higher proportion of all female HCWs (71%), except for health assistants (65.4%), expressed willingness to donate their breast milk if needed. Among males HCWs, the majority of those who were doctors (82.8%) and pharmacists (62.5%) expressed willingness to support their spouses to donate breast milk, and they also had higher acceptance of DHM for their infants. In all, more than 80% of the HCWs will encourage mothers to donate their milk and feed babies under their care with DHM, but only 47% would accept DHM to feed their own children. Health assistants had less favourable views, and negative perceptions were linked to the internet and media sources.

CONCLUSIONS

The study highlights health workers' awareness of DHM but indicates a reluctance to fully embrace it, especially among health assistants. The need for targeted education programs, to address knowledge gaps and negative perceptions, is crucial for the successful implementation of human milk banks in Nigeria. Overcoming challenges, such as safety concerns and sociocultural influences, requires focused efforts from policymakers and healthcare institutions.

Projected impact of fast-tracking of anti-retroviral treatment coverage on vertical transmission of HIV in India

One of the five high-level goals under Phase V of the National AIDS and STD Control Programme (NACP) of the Government of India is the elimination of vertical transmission of HIV. In this paper, we estimate the potential impact of maintaining and enhancing the anti-retroviral treatment under the NACP in terms of averting new infections and vertical transmission rates vis-à-vis no intervention scenario. We used India's HIV Estimates 2022 models to create treatment coverage scenarios of no interventions, status quo, business as usual, on-track and fast-track scenarios from 2023 to 2030. Our analysis indicates that fast-tracking scale-up of treatment services would avert almost 41000 child infections from 2023 to 2030 leading to a vertical transmission rate of around 7.70% in 2030 vis-a-vis no interventions scenario. Higher and sustained ART coverage would not only take the country closer to the elimination goals but would also prevent thousands of vertical transmissions, thus bringing a lot of benefits to HIV-positive pregnant women and their families. Supported by efforts for the prevention of new infections in the general population, India is on track for the attainment of elimination of vertical transmission of HIV by 2030.

Infant feeding knowledge, attitudes and practices of HIV-positive breastfeeding mothers

Background

Assessment of infant feeding knowledge, attitudes and practices of human immunodeficiency virus (HIV)-positive breastfeeding mothers may determine compliance with the chosen feeding method.

Aim

The study assessed knowledge, attitudes and practices on infant feeding among HIV-positive breastfeeding mothers.

Setting

The study was conducted at five clinics in the Chief Albert Luthuli sub-district of Mpumalanga, South Africa.

Methods

A descriptive cross-sectional study with a convenient sample of 155 HIV-positive breastfeeding mothers.

Results

More than half of the participants (54.8%) were knowledgeable of exclusive breastfeeding in general. However, less than half were knowledgeable of exclusive breastfeeding in the context of HIV (46.5%), mixed feeding (28.4%) and replacement feeding (49.0%). Most participants (85.8%) reported that they were advised to exclusively breastfeed for 6 months, 61.3% intended to exclusively breastfeed for 6 months, and 29% intended to stop breastfeeding at 6 months. Most participants (64.5%) intended to introduce solids at 6 months, and for participants who intended to introduce solids before 6 months, 37.7% did not believe that exclusive breastfeeding was sufficient for the baby.

Conclusion

Although most participants were knowledgeable about exclusive breastfeeding, there were misconceptions that required attention such as the lack of knowledge on exclusive breastfeeding in the context of HIV, mixed feeding and replacement feeding. Exclusive breastfeeding for 6 months was the most emphasised infant feeding practice.

Contribution

This study builds on existing literature on infant feeding knowledge, attitudes and practices and provides a basis for interventions for improved exclusive breastfeeding rates.

Feeding modalities, HIV transmission and its predictors among HIV-exposed infants visited Gamo and Gofa zones public health facilities, Southern Ethiopia: a retrospective follow up study

BACKGROUND

Despite the highest (88%) Prevention of Mother-To-Child Transmission (PMTCT) of HIV coverage in Eastern Africa, 50% of new HIV infections in children aged 0-14 years occur in the region.

OBJECTIVE

The aim of this study was to assess the feeding modalities, the rate of HIV transmission and its predictors among HIV exposed infants (HIV-EIs) visited Gamo and Gofa Zones public health facilities, Southern Ethiopia from January 2013 to February 2019.

METHOD AND MATERIALS

Institution-based retrospective follow up study was employed among 450 HIV-EIs having DNA/PCR test results. All infant-mother pair records in selected health facilities were reviewed using a standard data extraction tool from March to July 2019. HIV transmission probabilities were assessed by Kaplan-Meier time-to-event analysis method and log-rank tests were used to compare the risk among different groups. The Cox-proportional hazards model, adjusted on infant feeding modalities and other co-variants was used to identify predictors of HIV transmission, and statistical significance was declared at a p-value of < 0.05.

RESULTS

In total, 383 complete records were analyzed. In the study, 85.6% (95%CI: 81.6%, 89.1%) of HIV-EIs were exclusively breastfed in the first six months. The 18 months probability of infant HIV transmission was 64 (16.7%) (95%CI: 13.1%-20.8%). The risk of HIV-transmission was higher among infants who were delivered at the hospital than health centers/health posts (AHR = 3.07; 95%CI: 1.19, 7.95); discontinued Cotrimoxazole prophylaxis in at least one visit (AHR = 6.32; 95%CI: 3.35, 11.94); did not exclusively breastfeed (AHR = 3.07; 95%CI: 1.72, 5.47) and came from urban areas (AHR = 5.90; 95%CI: 1.40, 24.85).

CONCLUSIONS

The study showed that HIV-EIs had a greater rate of 18 months HIV transmission than the national pooled prevalence. The risk of transmission is higher among infants who do not breastfeed exclusively for the first 6 months, and the risk increases with the number of months spent by breastfeeding. Therefore, strengthening counselling on safer feeding options and Cotrimoxazole prophylaxis use; provision of quality PMTCT service with special focus in hospitals and urban residents were recommended.

Practices, support and stigma related to infant feeding and postpartum engagement in care among women living with HIV in Canada

Background: Breastfeeding is not recommended for women living with HIV (WLWH) in Canada. We described the prevalence of breastfeeding and explored experiences of care, support, and stigma related to infant feeding. Setting: Quebec, Ontario, and British Columbia (Canada). Methods: Data were obtained from the HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) surveys, conducted between 2013 and 2018. Results: Breastfeeding was reported by 73.5% of the 786 women who delivered before HIV diagnosis and 7.3% of the 289 women who delivered after HIV diagnosis. Among them, earlier year of delivery, delivery outside of Canada, and African, Caribbean, Black ethnicity were independently associated with increased odds of breastfeeding. Among WLWH who had a live birth during the last year, 77% (40/52) felt that they had received support regarding infant feeding practices, and 77% (23/30) were concerned that not breastfeeding could lead to them being identified as WLWH. Among 71 women within one year postpartum at any one of the study waves, 89% reported having an undetectable viral load. Conclusion: Breastfeeding experiences were common among WLWH, most often prior to HIV diagnosis. Fear of unintentional HIV status disclosure when not breastfeeding and challenges to maintain an undetectable HIV viral load are important issues to address during postpartum care.

Attitudes on breast feeding among persons with HIV who have given birth and their perceptions of coercion during counseling on safe infant feeding practices

Persons with HIV can receive mixed messages about the safety of breastfeeding. We sought to assess if they felt coerced to formula feed when counseled about practices to reduce HIV transmission. Persons with HIV who had given birth were eligible to complete a survey to describe their experiences with infant feeding counseling and if they felt coerced to formula feed. An Iowa Infant Feeding Attitude Scale (IIFAS) assessed attitudes towards breastfeeding. Qualitative analyses were performed on narrative responses. One hundred surveys were collected from sites in Georgia, North Carolina, Pennsylvania, and South Carolina. The mean IIFAS score (n, 85) was 47 (SD 9.2), suggesting relatively favorable attitudes toward breastfeeding. Thirteen persons reported feeling coerced to formula feed. When controlling for choosing to give any breast milk, persons with any college education were more likely to report feeling coerced (aOR 9.8 [95% CI 1.8-52.5]). Qualitative analyses revealed three themes: perceiving breastfeeding as unsafe, engaging in shared decision-making, and resisting advice to formula feed. Persons with HIV desire to be counseled about safe infant feeding practices and have their questions answered without judgement. We highlight experiences of persons with HIV that reflect a need for a nuanced approach to infant feeding counseling.

Maternal IgA2 Recognizes Similar Fractions of Colostrum and Fecal Neonatal Microbiota

Microbiota acquired during labor and through the first days of life contributes to the newborn's immune maturation and development. Mother provides probiotics and prebiotics factors through colostrum and maternal milk to shape the first neonatal microbiota. Previous works have reported that immunoglobulin A (IgA) secreted in colostrum is coating a fraction of maternal microbiota. Thus, to better characterize this IgA-microbiota association, we used flow cytometry coupled with 16S rRNA gene sequencing (IgA-Seq) in human colostrum and neonatal feces. We identified IgA bound bacteria (IgA+) and characterized their diversity and composition shared in colostrum fractions and neonatal fecal bacteria. We found that IgA2 is mainly associated with Bifidobacterium, Pseudomonas, Lactobacillus, and Paracoccus, among other genera shared in colostrum and neonatal fecal samples. We found that metabolic pathways related to epithelial adhesion and carbohydrate consumption are enriched within the IgA2+ fecal microbiota. The association of IgA2 with specific bacteria could be explained because these antibodies recognize common antigens expressed on the surface of these bacterial genera. Our data suggest a preferential targeting of commensal bacteria by IgA2, revealing a possible function of maternal IgA2 in the shaping of the fecal microbial composition in the neonate during the first days of life.

Childbirth Care among SARS-CoV-2 Positive Women in Italy

The new coronavirus emergency spread to Italy when little was known about the infection’s impact on mothers and newborns. This study aims to describe the extent to which clinical practice has protected childbirth physiology and preserved the mother–child bond during the first wave of the pandemic in Italy. A national population-based prospective cohort study was performed enrolling women with confirmed SARS-CoV-2 infection admitted for childbirth to any Italian hospital from 25 February to 31 July 2020. All cases were prospectively notified, and information on peripartum care (mother–newborn separation, skin-to-skin contact, breastfeeding, and rooming-in) and maternal and perinatal outcomes were collected in a structured form and entered in a web-based secure system. The paper describes a cohort of 525 SARS-CoV-2 positive women who gave birth. At hospital admission, 44.8% of the cohort was asymptomatic. At delivery, 51.9% of the mothers had a birth support person in the delivery room; the average caesarean section rate of 33.7% remained stable compared to the national figure. On average, 39.0% of mothers were separated from their newborns at birth, 26.6% practised skin-to-skin, 72.1% roomed in with their babies, and 79.6% of the infants received their mother’s milk. The infants separated and not separated from their SARS-CoV-2 positive mothers both had good outcomes. At the beginning of the pandemic, childbirth raised awareness and concern due to limited available evidence and led to “better safe than sorry” care choices. An improvement of the peripartum care indicators was observed over time.

After their wives have delivered, a lot of men like going out: Perceptions of HIV transmission risk and support for HIV prevention methods during breastfeeding in sub-Saharan Africa

Female-initiated HIV prevention methods, such as oral pre-exposure prophylaxis (PrEP) and the vaginal ring, may be important risk reduction strategies for breastfeeding women. Given their novelty, information about the sociocultural context and how it influences perceptions of and support for their use during breastfeeding is lacking. To address this gap, we conducted 23 focus group discussions separately with pregnant and breastfeeding women, male partners and grandmothers (N = 196) and 36 in-depth interviews with key informants in Malawi, South Africa, Uganda and Zimbabwe. We analysed the data using a framework analysis method. Overall, breastfeeding was the norm, and participants described the transference of health (e.g., nutrition) and disease (e.g., HIV) to children through breast milk. Participants considered the early breastfeeding period as one of high HIV transmission risk for women. They explained that male partners tend to seek outside sexual partners during this period because women need time to recover from delivery, women focus their attention on the child, and some men are disgusted by breast milk. Participants highlighted concerns about the drugs in oral PrEP transferring to the child through breast milk, but fewer worried about the effects of the vaginal ring because the drug is localized. Women, grandmothers and key informants were supportive of women using these HIV prevention methods during breastfeeding, while male partners had mixed opinions. These findings can be used to tailor messages for promoting the use of PrEP or the vaginal ring during breastfeeding in sub-Saharan Africa.

Perinatal depressive symptoms and breastfeeding behaviors: A systematic literature review and biosocial research agenda

BACKGROUND

Breastfeeding is recommended to improve maternal and infant health globally. Depression has been posited to negatively impact breastfeeding, although potential causal and bidirectional pathways between these two phenomena have not been sufficiently characterized. We therefore conducted a systematic review to critically evaluate available evidence on the relationship between perinatal depressive symptoms and breastfeeding behaviors; to identify knowledge gaps and propose a biosocial research agenda to advance our understanding of this topic.

METHODS

A systematic search strategy was applied across seven databases. Data were extracted and aggregated using the matrix method to provide a narrative synthesis of findings.

RESULTS

Thirty-eight studies from 20 countries spanning 1988 through 2018 fit the inclusion criteria. In general, methods across studies were heterogeneous. Fourteen different tools were used to measure perinatal depressive symptoms. Nearly half the studies did not provide breastfeeding definitions. No studies from low-income countries met inclusion criteria. More than half (63%) of studies demonstrated a negative association between depressive symptoms across the perinatal period and less exclusive breastfeeding and/or shorter breastfeeding durations.

LIMITATIONS

Heterogeneity in study design, definitions, assessment tools, and measurement time points limited the comparability of study findings. Causality cannot be assessed.

CONCLUSIONS

Available evidence suggests perinatal depressive symptoms negatively associated with breastfeeding exclusivity and duration, which can lead to suboptimal infant nutrition and detrimental impacts on maternal mental and physical health. To better understand this relationship, we propose including consistent operationalization and assessment of depression and breastfeeding globally and concurrent repeated measures of key biological and social factors.

Assessing Medical Neglect in HIV-Exposed or Infected Children

Human Immunodeficiency Virus (HIV) causes a chronic illness requiring lifelong medical care to prevent opportunistic infections and death. It is important to identify medical neglect in children that are perinatally exposed to or living with human immunodeficiency virus and to take steps to prevent it. Diagnosis of medical neglect must be considered in the context of the caregivers' understanding of the risks of harm, and the logistical, cultural and social factors that may influence their actions or non-actions. When medical neglect as failure of treatment or prevention of infection is suspected, medical providers should work collaboratively with caregivers to assess and address barriers to adherence and to provide resources and support. Medical neglect may be diagnosed if repeated preventive efforts fail.

Acceptability of donor breastmilk banking among health workers: a cross-sectional survey in Zimbabwean urban settings

BACKGROUND

The World Health Organization (WHO) recommends that donor human milk is superior to artificial infant formula in situations where the baby cannot feed on the mother's breastmilk. The purpose of this study was to determine the acceptability of donor human milk banking among health workers in Zimbabwean urban settings.

METHODS

A cross sectional study was conducted among 535 health workers and 15 key informants. Three referral hospitals were purposively selected and systematic random sampling was used to select the health workers. The study was conducted between October 2017 and October 2018.

RESULTS

The concept of donor human milk banking was acceptable among health workers. One-third (31%) of the study participants reported that they would accept donor breastmilk for their children while 56% of them would encourage their clients to donate breastmilk. Acceptance of donor human milk banking was associated with a high level of knowledge on breastmilk banks (p = 0.009) and the study participants' health profession (p = 0.001). Clinical staff were more receptive to donor human milk banking compared to non-clinical health workers. Donor human milk banking was not associated with religion (p = 0.498) or marital status (p = 0.714).

CONCLUSIONS

The results showed that health workers and policy informers would accept the establishment of breastmilk banks subject to resource availability. Commitment to the establishment of breastmilk banks was moderately acceptable among opinion leaders responsible for spearheading health and nutrition policies.

Protocol for the evaluation of the population-level impact of Zimbabwe's prevention of mother-to-child HIV transmission program option B+: a community based serial cross-sectional study

Background

WHO recommends that HIV infected women receive antiretroviral therapy (ART) minimally during pregnancy and breastfeeding (“Option B”), or ideally throughout their lives regardless of clinical stage (“Option B+”) (Coovadia et al., Lancet 379:221–228, 2012). Although these recommendations were based on clinical trials demonstrating the efficacy of ART during pregnancy and breastfeeding, the population-level effectiveness of Option B+ is unknown, as are retention on ART beyond the immediate post-partum period, and the relative impact and cost-effectiveness of Option B+ compared to Option A (Centers for Disease Control and Prevention, Morb Mortal Wkly Rep 62:148–151, 2013; Ahmed et al., Curr Opin HIV AIDS 8:473–488, 2013). To address these issues, we conducted an impact evaluation of Zimbabwe’s prevention of mother to child transmission programme conducted between 2011 and 2018 using serial, community-based cross-sectional serosurveys, which spanned changes in WHO recommendations. Here we describe the rationale for the design and analysis.

Methods/design

Our method is to survey mother-infant pairs residing in the catchment areas of 157 health facilities randomly selected from 5 of 10 provinces in Zimbabwe. We collect questionnaires, blood samples from mothers and babies for HIV antibody and viral load testing, and verbal autopsies for deceased mothers/babies. Using this approach, we collected data from two previous time points: 2012 (pre-Option A standard of care), 2014 (post-Option A / pre-Option B+) and will collect a third round of data in 2017–18 (post Option B+ implementation) to monitor population-level trends in mother-to-child transmission of HIV (MTCT) and HIV-free infant survival. In addition, we will collect detailed information on facility level factors that may influence service delivery and costs.

Discussion

Although the efficacy of antiretroviral therapy (ART) during pregnancy and breastfeeding for prevention of mother-to-child transmission of HIV (PMTCT) has been well-documented in randomized trials, little evidence exists on the population-level impact and cost-effectiveness of Option B+ or the influence of the facility on implementation (Siegfried et al., Cochrane Libr 7:CD003510, 2017). This study will provide essential data on these gaps and will provide estimates on retention in care among Option B+ clients after the breastfeeding period.

Increasing trend of exclusive breastfeeding over 12 years period (2002-2014) among women in Moshi, Tanzania

BACKGROUND

The World Health Organization has recommended that all infants under 6 months should be exclusively breastfed. An understanding of the trend of exclusive breastfeeding (EBF) over years and over smaller geographical areas is crucial to monitor the progress made in improving the proportions of infants' EBF.

METHODS

Data on infant feeding practices on 2315 mother-infant pairs from 2002 to 2014 were extracted from cohorts of women who delivered in the Moshi Municipality. Descriptive statistics were used to establish the trend of EBF up to 1, 3 and 6 months across waves (2002/2004 = wave I, 2005/2012 = wave II and 2013/2014 = wave III), to relate EBF up to 6 months to wealth quintiles and to HIV status of mothers.

RESULTS

The number of mothers in waves I, II and III were 1656 (71.5%), 256 (11.1%) and 403(17.4%) respectively. The percentages of EBF up to 6 months increased from 5.5, 13.7 to 16.9% from wave I to III. Overall, across the waves, the proportion of EBF up to 6 months among the mothers in the low wealth quintile was 4, 9 and 42%, and 7, 26 and 15% for the ones in the highest wealth quintile. The proportion of EBF up to 6 months has been increasing among HIV positive mothers while fluctuating among their counterparts across the waves.

CONCLUSION

The proportion of EBF up to 6 months has been increasing in the Moshi municipality but is below the national average. While establishing trends of EBF at the national level is commendable, research to establish trends over smaller geographical areas is needed to provide a true picture that may otherwise be masked.

HIV Exposure and Formula Feeding Predict Under-2 Mortality in HIV-Uninfected Children, Botswana

OBJECTIVES

To prospectively assess rates and detailed predictors of morbidity and mortality among HIV-exposed uninfected children and HIV-unexposed children in Botswana in a more recent era.

STUDY DESIGN

We enrolled HIV-infected and HIV-uninfected mothers and their children in the prospective observational Tshipidi study at 2 sites (1 city and 1 village) in Botswana from May 2010-July 2012. Live-born children and their mothers were followed for 24 months postpartum. Detailed sociodemographic data, health, and psychosocial characteristics were collected at baseline and prospectively, and health outcomes ascertained. Mothers chose infant feeding method with counselling.

RESULTS

A total of 893 live-born HIV-uninfected children (436 HIV-exposed uninfected, 457 HIV-unexposed) were followed. HIV-infected mothers had a median CD4 count of 410 cells/mm3, 32% took 3-drug antiretroviral treatment during pregnancy, 67% took only zidovudine, and 1% took <2 weeks of any antiretrovirals antepartum. Twenty four-month vital status was available for 888 (99.4%) children. HIV-exposed uninfected children had a significantly higher risk of death compared with children of HIV-uninfected mothers (5.0% vs 1.8%) (adjusted hazard ratio 3.27, 95% CI 1.44-7.40). High collinearity between maternal HIV status and child feeding method precluded analysis of these factors as independent predictors of mortality. Preterm birth, low birth weight, and congenital anomaly were also associated with mortality (in separate analyses), but maternal socioeconomic factors, depression, substance use, and social support were not significant predictors.

CONCLUSIONS

The strongest predictors of 24-month mortality among children in Botswana were HIV exposure and formula feeding, although the relative contribution of these factors to child health could not be separated.

Capturing Changes in HIV-Infected Breastfeeding Mothers' Cognitive Processes from Before Delivery to 5 Months Postpartum: An Application of the Pile-Sorting Technique in Haiti

BACKGROUND

The cognitive processes involved in individuals' perceptions and prioritization of information, and how these change with experience or exposure to interventions, are rarely examined in the evaluation of nutrition interventions. Exclusive breastfeeding counseling is a common infant and young-child feeding intervention and is used to promote HIV-free survival in the prevention of mother-to-child transmission programs. However, it is often designed without adequate attention to the changes in mothers' perceptions over the course of their early breastfeeding experiences.

OBJECTIVE

The aim of this study was to identify HIV-infected breastfeeding mothers' cognitive structure (their organization of messages and ideas) of infant feeding messages and to characterize whether their cognitive organization of infant feeding messages changed from pregnancy through the first 5 mo postpartum.

METHODS

With the use of semistructured interviews and the cognitive mapping technique of pile sorting, we interviewed 30 HIV-infected breastfeeding mothers in Port-au-Prince, Haiti. We asked them to sort and rate 18 infant feeding messages 3 times (during pregnancy, 0- to 1-mo postpartum, and 3- to 5-mo postpartum). We analyzed their responses by using multidimensional scaling, property fitting, and partition analyses.

RESULTS

At all 3 visits, we found consistency in women's cognitive mapping of messages. For example, mothers consistently differentiated messages pertinent for exclusive breastfeeding compared with those that pertained to other practices. However, subtle variations in mothers' cognition over time were also evident, particularly at 0- to 1-mo postpartum, when message proximity was tightly clustered compared with the earlier and later periods.

CONCLUSIONS

We conclude that mothers share a common cognitive organization of infant feeding messages and that this organization changes over time. Attention to variations in cognition can support context-sensitive, patient-centered counseling by practitioners and improve the effectiveness of nutrition interventions. Pile sorting is an efficient, systematic technique to examine cognitive processes related to health and nutrition.

"I beg you…breastfeed the baby, things changed": infant feeding experiences among Ugandan mothers living with HIV in the context of evolving guidelines to prevent postnatal transmission

BACKGROUND

For women living with HIV (WLWH) in low- and middle-income countries, World Health Organization (WHO) infant feeding guidelines now recommend exclusive breastfeeding until six months followed by mixed feeding until 24 months, alongside lifelong maternal antiretroviral therapy (ART). These recommendations represent the sixth major revision to WHO infant feeding guidelines since 1992. We explored how WLWH in rural Uganda make infant feeding decisions in light of evolving recommendations.

METHODS

We conducted semi-structured interviews with 20 postpartum Ugandan WLWH accessing ART, who reported pregnancy < 2 years prior to recruitment. Interviews were conducted between February-August 2014 with babies born between March 2012-October 2013, over which time, the regional HIV treatment clinic recommended lifelong ART for all pregnant and breastfeeding women (Option B+). Content analysis was used to identify major themes. Infant feeding experiences was an emergent theme. NVivo 10 software was used to organize analyses.

RESULTS

Among 20 women, median age was 33 years [IQR: 28-35], number of livebirths was 3 [IQR: 2-5], years on ART was 2.3 [IQR: 1.5-5.1], and 95% were virally suppressed. Data revealed that women valued opportunities to reduce postnatal transmission. However, women made infant feeding choices that differed from recommendations due to: (1) perception of conflicting recommendations regarding infant feeding; (2) fear of prolonged infant HIV exposure through breastfeeding; and (3) social and structural constraints shaping infant feeding decision-making.

CONCLUSIONS

WLWH face layered challenges navigating evolving infant feeding recommendations. Further research is needed to examine guidance and decision-making on infant feeding choices to improve postpartum experiences and outcomes. Improved communication about changes to recommendations is needed for WLWH, their partners, community members, and healthcare providers.

HIV status disclosure among postpartum women in rural Tanzania: predictors, experiences and uptake of a nurse-facilitated disclosure intervention

HIV status disclosure is a key support strategy to start and maintain HIV care and treatment and to reduce HIV transmission. We explored the patterns and correlates of disclosure and described the effectiveness of nurse-facilitated disclosure among HIV-infected mothers of infants in coastal Tanzania. We enrolled 400 HIV positive women in an observational longitudinal study in 2011, interviewed them about maternal sociodemographic and economic characteristics, maternal and child health and history of HIV disclosure experiences and offered nurse-facilitated HIV disclosure at enrolment or at follow-up 1 month later. Mothers frequently disclosed their status to husbands and/or female relatives and experienced predominantly positive reactions. Economically vulnerable women disclosed more often to elderly female relatives, indicating that Infant and Young Child Feeding counseling given to HIV positive women should garner the support of elderly female relatives for implementing appropriate feeding practices. Nurse-facilitated disclosure was feasible in this low resource setting and was used by patients to help them with both first-time disclosure and disclosure to new persons.

Measuring exclusive breastfeeding social support: Scale development and validation in Uganda

The World Health Organization recommends exclusive breastfeeding (EBF) for 6 months and continued breastfeeding for at least 2 years. Social support has been widely recognized to influence breastfeeding practices. However, existing scales do not measure exclusive breastfeeding social support (EBFSS), rather they assess social support for any breastfeeding. Further, they are tailored towards high-income settings. Therefore, our objectives were to develop and validate a tool to measure EBFSS in low-income settings. To develop the scale, local and international breastfeeding experts were consulted on modifications to the Hughes' Breastfeeding Social Support Scale. It was then implemented in an observational cohort in Gulu, Uganda, at 1 (n = 238) and 3 (n = 237) months post-partum (NCT02925429). We performed polychoric and polyserial correlations to remove redundant items and exploratory factor analysis at 1 month post-partum to determine the latent factor structure of EBFSS. We further applied confirmatory factor analysis to assess dimensionality of the scale at 3 months post-partum. We then conducted tests of predictive, convergent, and discriminant validity against EBF, self-efficacy, general social support, and depression. The modification of the Hughes' scale resulted in 18 items, which were reduced to 16 after examining variances and factor loadings. Three dimensions of support emerged: Instrumental, Emotional, and Informational, with alpha coefficients of 0.79, 0.85, and 0.83, respectively. Predictive, convergent, and discriminant validity of the resultant EBFSS scale was supported. The EBFSS scale is valid and reliable for measuring EBFSS in northern Uganda and may be of use in other low-income settings to assess determinants of EBF.

Advancing methods for research on household water insecurity: Studying entitlements and capabilities, socio-cultural dynamics, and political processes, institutions and governance

Household water insecurity has serious implications for the health, livelihoods and wellbeing of people around the world. Existing methods to assess the state of household water insecurity focus largely on water quality, quantity or adequacy, source or reliability, and affordability. These methods have significant advantages in terms of their simplicity and comparability, but are widely recognized to oversimplify and underestimate the global burden of household water insecurity. In contrast, a broader definition of household water insecurity should include entitlements and human capabilities, sociocultural dynamics, and political institutions and processes. This paper proposes a mix of qualitative and quantitative methods that can be widely adopted across cultural, geographic, and demographic contexts to assess hard-to-measure dimensions of household water insecurity. In doing so, it critically evaluates existing methods for assessing household water insecurity and suggests ways in which methodological innovations advance a broader definition of household water insecurity.

Who knows what: An exploration of the infant feeding message environment and intracultural differences in Port-au-Prince, Haiti

Worldwide, mothers with young children receive many messages about infant feeding. Some messages are generated by health providers and others by the households, communities, and social contexts in which women live. We aimed to determine the scope of infant feeding messages in urban Haiti and to examine intracultural differences in salience of these messages and their alignment with international guidelines. We applied the method of free listing with 13 health workers and 15 human immunodeficiency virus (HIV)-infected and 15 HIV-uninfected mothers with infants 0-6 months old at Groupe Haïtien d'Etude du Sarcome de Kaposi et des Infections Opportunistes in Port-au-Prince, Haiti. Participants listed all messages women receive about infant feeding and specifically about HIV and infant feeding. Message salience was determined by frequency of mention and recall order; messages were coded for key themes. For all groups, the World Health Organization infant feeding recommendations were salient, especially those related to exclusive breastfeeding. Messages across all groups focused on infant health outcomes, with less emphasis on maternal outcomes. Cultural beliefs were also elicited and showed higher salience for mothers than health workers, particularly for consequences of poor maternal nutrition. Health workers' free lists were poorly correlated to those of mothers, whereas those of mothers were highly correlated, regardless of HIV status. Inasmuch as many salient messages were culturally generated, and differences existed between mothers and health workers, we conclude that it is important for health workers to acknowledge the broader infant feeding message environment, and discrepancies within that environment, to address successes and failures in the messages reaching mothers, given potential consequences for mothers' breastfeeding behaviours.

Negotiations of Blame and Care among HIV-positive Mothers and Daughters in South Africa's Eastern Cape

Research delineates two epidemiological categories among HIV-positive adolescents: those who contract the virus sexually and those who inherit it as infants. In this article, we are interested in how tacit inferences about adolescents' mode of infection contribute to their experiences of HIV-related blame, and their ability to achieve care, in their intimate, everyday settings. The analysis arises from ethnographic research with 23 HIV-positive adolescents living in South Africa's Eastern Cape. From these, we draw particularly on the narratives of four HIV-positive teenage girls and their HIV-positive mothers. The article explores the social stakes entailed in ascriptions of adolescents' mode of infection, particularly in terms of how blame was allocated between mothers and daughters. It further considers how these families have sought to negotiate repudiation and thereby sustain intergenerational care. The article furthers limited research on the life projects and dilemmas of this HIV-positive adolescent cohort.

Promotion of exclusive breastfeeding among HIV-positive mothers: an exploratory qualitative study

Background

Exclusive breastfeeding has the potential to reduce infant and under-five mortality, but research shows the practice is not widespread in resource-poor settings of sub-Saharan Africa. We explored factors influencing the decision to exclusively breastfeed among HIV-positive mothers accessing interventions for prevention of mother-to-child transmission of HIV in selected sites of Zambia.

Methods

This exploratory qualitative study was embedded in research conducted on: HIV and infant feeding; choices and decision-outcomes in the context of prevention of mother-to-child transmission among HIV-positive mothers in Zambia. Thirty HIV-positive mothers and six key informants were recruited from two health facilities providing mother-to-child HIV transmission prevention services. A semi-structured guide was used to conduct interviews, which were digitally recorded and simultaneously transcribed. Data coding and analysis was done with the support of QRS Nvivo 10 version software.

Results

Despite the known benefits of exclusive breastfeeding, gaps in understanding and potential for behaviour change remained. We found that information promoting exclusive breastfeeding may have been understood by mothers as instructions from the health care workers indicating how to feed their HIV-exposed babies rather than as an option for the mothers’ own informed-decision. This understanding influenced a mother’s perceptions of breast milk safety while on antiretroviral medicine, of the formula feeding option, and of the baby crying after breastfeeding. The meanings mothers attached to exclusive breastfeeding thus influenced their understanding of breast milk insufficiency, abrupt weaning and mixed feeding in the context of preventing mother-to-child transmission of HIV.

Conclusion

In order to enhance feeding practices for HIV-exposed infants, our study suggests a broader health campaign supporting all mothers to exclusively breastfeed.

Breastfeeding and Complementary Feeding Practices among HIV-Exposed Infants in Coastal Tanzania

BACKGROUND

Appropriate infant feeding is a persistent challenge for human immunodeficiency virus (HIV)-infected mothers in sub-Saharan Africa.

OBJECTIVE

This study aimed to describe correlates of infant feeding among HIV-infected mothers in coastal Tanzania.

METHODS

HIV-infected women (n = 400) with infants younger than 18 months were enrolled from June to November 2011 from 3 public health facilities in Pwani, Tanzania: Tumbi Regional Hospital (TRH), Chalinze Health Center (CHC), and Bagamoyo District Hospital (BDH). Participants were surveyed about sociodemographics and infant feeding behavior at enrollment; infant feeding data were collected prospectively and retrospectively in the month of study follow-up.

RESULTS

Statistically significant correlates of exclusive breastfeeding (EBF) were infant age (months) (adjusted odds ratio [AOR] = 0.6; 95% confidence interval [CI], 0.5-0.9), enrollment facility (TRH: reference; CHC: AOR = 5.0, 95% CI, 1.2-20.8; BDH: AOR = 11.6, 95% CI, 2.3-59.9), and HIV disclosure to one's mother (AOR = 0.2; 95% CI, 0.1-0.6). Exclusive breastfeeding prevalence among infants younger than 6 months was 77%, but 50% of infants older than 6 months no longer receiving breast milk did not receive animal source foods (ASF) daily. Enrollment facility (TRH: reference; CHC: AOR = 0.2, 95% CI, 0.1-1.0; BDH: AOR = 0.1, 95% CI, 0.01-0.4) and HIV disclosure (to mother-in-law: AOR = 0.2, 95% CI, 0.1-0.8; to brother: AOR = 0.3, 95% CI, 0.1-0.8) were negatively associated with ASF provision.

CONCLUSION

High prevalence of EBF suggests that it is an attainable behavior, whereas low prevalence of daily ASF provision suggests that adequate diets are difficult to achieve after breastfeeding cessation. These findings support current recommendations for HIV-infected mothers in resource-poor regions to continue breastfeeding for at least 1 year and suggest the need for greater support with complementary feeding. Associations between HIV disclosure and infant feeding merit further exploration, and correlations between enrollment facility and infant feeding highlight the potential influence of clinics on achieving infant feeding recommendations.

Household food insecurity, maternal nutritional status, and infant feeding practices among HIV-infected Ugandan women receiving combination antiretroviral therapy

Household food insecurity (HHFI) may be a barrier to both optimal maternal nutritional status and infant feeding practices, but few studies have tested this relationship quantitatively, and never among HIV-infected individuals. We therefore described the prevalence of HHFI and explored if it was associated with poorer maternal nutritional status, shorter duration of exclusive breastfeeding (EBF) and fewer animal-source complementary foods. We assessed these outcomes using bivariate and multivariate analyses among 178 HIV-infected pregnant and breastfeeding (BF) women receiving combination antiretroviral therapy in the PROMOTE trial (NCT00993031), a prospective, longitudinal cohort study in Tororo, Uganda. HHFI was common; the prevalence of severe, moderate, and little to no household hunger was 7.3, 39.9, and 52.8 %, respectively. Poor maternal nutritional status was common and women in households experiencing moderate to severe household hunger (MSHH) had statistically significantly lower body mass index (BMIs) at enrollment (21.3 vs. 22.5, p < 0.01) and prior to delivery (22.6 vs. 23.8, p < 0.01). BMI across time during pregnancy, but not gestational weight gain, was significantly lower for MSHH [adjusted beta (95 % CI) -0.79 (-1.56, -0.02), p = 0.04; -2.06 (-4.31, 0.19), p = 0.07], respectively. The prevalence (95 % CI) of EBF at 6 months was 67.2 % (59.7-73.5 %), and the proportion of women BF at 12 months was 80.4 % (73.3-85.7 %). MSHH was not associated with prevalence of EBF at 6 months or BF at 12 months. However, among those women still EBF at 4 months (81.4 % of population), those experiencing MSHH were significantly more likely to cease EBF between 4 and 6 months (aHR 2.38, 95 % CI 1.02-5.58). The prevalence of HHFI, maternal malnutrition, and suboptimal infant feeding practices are high and the causal relationships among these phenomena must be further explored.

Missing HIV prevention opportunities in South African children--a 7-year review

BACKGROUND

The prevention of mother-to-child transmission (PMTCT) program in South Africa is now successful in ensuring HIV-free survival for most HIV-exposed children, but gaps in PMTCT coverage remain. The study objective was to identify missed opportunities for prevention of mother-to-child transmission of HIV using the four PMTCT stages outlined in National Guidelines.

METHODS

This descriptive study enrolled HIV-exposed children who were below the age of 7 years and therefore born during the South African PMTCT era. The study site was in Gauteng, South Africa and enrolment was from June 2009 to May 2010. The clinical history was obtained through a structured caregiver interview and review of medical records and included socio-demographic data, medical history, HIV interventions, infant feeding information and HIV results. The study group was divided into the "single dose nevirapine" ("sdNVP") and "dual-therapy" (nevirapine & zidovudine) groups due to PMTCT program change in February 2008, with subsequent comparison between the groups regarding PMTCT steps during the preconception stage, antenatal care, labor and delivery and postpartum care.

RESULTS

Two-hundred-and-one HIV-exposed children were enrolled: 137 (68%) children were HIV infected and 64 (32%) were HIV uninfected. All children were born between 2002 and 2009, with 78 (39%) in the "sdNVP" and 123 (61%) in the "dual-therapy" groups. The results demonstrate significant improvements in antenatal HIV testing and PMTCT enrolment, known maternal HIV diagnosis at delivery, mother-infant antiretroviral interventions, infant HIV-diagnosis and cotrimoxazole prophylaxis. Missed opportunities without improvement include pre-conceptual HIV-services and family planning, tuberculosis screening, HIV disclosure, psychosocial support and postnatal care. Not receiving consistent infant feeding messaging was the only PMTCT component that worsened over time.

CONCLUSIONS

Multiple missed opportunities for optimal PMTCT were identified, which collectively increase children's risk of HIV acquisition. Although HIV-testing and antiretroviral interventions improved, all PMTCT components need to be optimized to reach the goal of total pediatric HIV elimination.

A review of the role of food insecurity in adherence to care and treatment among adult and pediatric populations living with HIV and AIDS

Adherence to antiretroviral therapy (ART) is critical for reducing HIV/AIDS morbidity and mortality. Food insecurity (FI) is emerging as an important barrier to adherence to care and treatment recommendations for people living with HIV (PLHIV), but this relationship has not been comprehensively examined. Therefore, we reviewed the literature to explore how FI may impact ART adherence, retention in medical care, and adherence to health care recommendations among PLHIV. We found data to support FI as a critical barrier to adherence to ART and to other health care recommendations among HIV-infected adults, HIV-infected pregnant women and their HIV-exposed infants, and child and adolescent populations of PLHIV. Associations between FI and ART non-adherence were seen in qualitative and quantitative studies. We identified a number of mechanisms to explain how food insecurity and ART non-adherence may be causally linked, including the exacerbation of hunger or ART side effects in the absence of adequate food and competing resource demands. Interventions that address FI may improve adherence to care and treatment recommendations for PLHIV.

Challenges faced by health-care providers offering infant-feeding counseling to HIV-positive women in sub-Saharan Africa: a review of current research

Exclusive breastfeeding (EBF) has been identified as the optimal nutrition and critical behavior in attaining human immunodeficiency virus (HIV)-free infant survival in resource-limited settings. Health-care providers (HCPs) in clinic- and community-settings throughout sub-Saharan Africa (sSA) provide infant-feeding counseling. However, rates of EBF at 6 months of age are suboptimal. HCPs are uniquely positioned to educate HIV-positive mothers and provide support by addressing known barriers to EBF. However, limited evidence exists on the experiences faced by HCPs in providing counseling on infant feeding to HIV-positive women. Our objective is to describe experiences faced by HCPs when delivering infant-feeding counseling in the context of HIV in program settings in sSA. We searched a range of electronic databases, including PubMed, CINAHL, and PsycINFO from January 1990 to February 2013, in addition to hand-searching, cross-reference searching, and personal communications. The search was limited to publications in English. Empirical studies of HCP experiences providing infant-feeding counseling in the prevention of mother-to-child transmission (PMTCT) of HIV programs in sSA were selected. We identified 10 peer-reviewed articles reporting HCP challenges in infant-feeding counseling that met inclusion criteria. Articles included qualitative, cross-sectional and mixed-method studies, and cumulatively reported 31 challenges faced by HCPs. Among the challenges identified, the most commonly reported were personal beliefs held by the HCPs toward infant feeding in the context of HIV, contradictory messages, staff workload, directive counseling styles, and a lack of practical strategies to offer mothers, often leading to improvised counseling approaches. Counseling strategies need to be developed that are relevant, meaningful, and responsive to the needs of both HCPs and mothers.

Temporal changes in the outcomes of HIV-exposed infants in Kinshasa, Democratic Republic of Congo during a period of rapidly evolving guidelines for care (2007-2013)

OBJECTIVE

Guidelines for prevention of mother-to-child transmission of HIV have developed rapidly, yet little is known about how outcomes of HIV-exposed infants have changed over time. We describe HIV-exposed infant outcomes in Kinshasa, Democratic Republic of Congo, between 2007 and 2013.

DESIGN

Cohort study of mother-infant pairs enrolled in family-centered comprehensive HIV care.

METHODS

Accounting for competing risks, we estimated the cumulative incidences of early infant diagnosis, HIV transmission, death, loss to follow-up, and combination antiretroviral therapy (cART) initiation for infants enrolled in three periods (2007-2008, 2009-2010, and 2011-2012).

RESULTS

1707 HIV-exposed infants enrolled at a median age of 2.6 weeks. Among infants whose mothers had recently enrolled into HIV care (N = 1411), access to EID by age two months increased from 28% (95% confidence limits [CL]: 24,34%) among infants enrolled in 2007-2008 to 63% (95% CL: 59,68%) among infants enrolled in 2011-2012 (Gray's p-value <0.01). The 18-month cumulative incidence of HIV declined from 16% (95% CL: 11,22%) for infants enrolled in 2007-2008 to 11% (95% CL: 8,16%) for infants enrolled in 2011-2012 (Gray's p-value = 0.19). The 18-month cumulative incidence of death also declined, from 8% (95% CL: 5,12%) to 3% (95% CL: 2,5%) (Gray's p-value = 0.02). LTFU did not improve, with 18-month cumulative incidences of 19% (95% CL: 15,23%) for infants enrolled in 2007-2008 and 22% (95% CL: 18,26%) for infants enrolled in 2011-2012 (Gray's p-value = 0.06). Among HIV-infected infants, the 24-month cumulative incidence of cART increased from 61% (95% CL: 43,75%) to 97% (95% CL: 82,100%) (Gray's p-value <0.01); the median age at cART decreased from 17.9 to 9.3 months. Outcomes were better for infants whose mothers enrolled before pregnancy.

CONCLUSIONS

We observed encouraging improvements, but continued efforts are needed.

Evaluation of the nutritional status of infants from mothers tested positive to HIV/AIDS in the health district of Dschang, Cameroon

INTRODUCTION

Poor infant feeding practices are common in Africa, resulting in physical and intellectual developmental impairments. Good feeding practices are crucial, especially in the first year of growth. HIV/AIDS has worsened the clinical and nutritional status of both mothers and their children, exacerbating high rates of malnutrition. The aim of this study was to assess by participative approach, the nutritional status of infants from mothers tested positive to HIV in the health district of Dschang.

METHODS

This is a cross sectional study with a period of recruitment of 2 years (2010-2012). Data Collection was done by the aim of a personal slip followed by training to strengthen the nutritional and hygienic capacity of targeted parents. Height and weight of infants were measured and body mass index (BMI) calculated.

RESULTS

Significant difference (p ≤ 0.05) was noticed in height-for-age z-score (HAZ) of girls aged between 1 to 2 years compared to 1-year old girls as well as to boys of all ages, defining them as stunted. Furthermore, the weight-for-age z-score (WAZ) results indicate that both girls and boys of all age are in moderate state of malnutrition. The results of BMI thinness classified according to gender and age groups, indicates that most infants (68/130, 52.3%) showed grade 2 thinness predominantly in 2-years old both boys and girls. However, no participants fall within the normal category for age and sex, as well as overweight and obesity categories.

CONCLUSION

Undernutrition exists among infants from mothers tested positive to HIV residing in Dschang, as most of the infants are underweight, and malnourished.

"Why Aren't You Breastfeeding?": How Mothers Living With HIV Talk About Infant Feeding in a "Breast Is Best" World

Infant feeding raises unique concerns for mothers living with HIV in Canada, where they are recommended to avoid breastfeeding yet live in a social context of "breast is best." In narrative interviews with HIV-positive mothers from Ontario, Canada, a range of feelings regarding not breastfeeding was expressed, balancing feelings of loss and self-blame with the view of responsibility and "good mothering" under the current Canadian guidelines. Acknowledging responsibility to put their child's health first, participants revealed that their choices were influenced by variations in social and cultural norms, messaging, and guidelines regarding breastfeeding across geographical contexts. This qualitative study raises key questions about the impact of breastfeeding messaging and guidelines for HIV-positive women in Canada.

Predictors of breastfeeding cessation among HIV infected mothers in Southern Ethiopia: a survival analysis

Background

Mother-to-child transmission (MTCT) of Human immunodeficiency virus (HIV) through breastfeeding remains the most significant route infection among children. Although the current guideline is recommending continued breastfeeding for HIV exposed infants, significant proportion of infants have been subjected to early weaning to prevent HIV transmission. However the predictors of breastfeeding cessation among HIV positive mothers were not documented in Ethiopia. Therefore the objective of this study was to determine the predictors of breastfeeding cessation among HIV-infected women in Southern Ethiopia.

Methods

A facility based cross sectional study was conducted in Southern Ethiopia. The samples were selected by cluster sampling technique. The Kaplan-Meier curve was used to describe the survival time of breastfeeding and a step-wise multivariable Cox-proportional hazards regression model were used to identify the predictors of breastfeeding cessation. Both crude and adjusted hazard ratio were determined and p<0.05 was considered as statistically significant.

Result

The mean duration of breastfeeding among HIV positive mothers was 13.79 [95% CI: (12.97–14.59)] months. The Kaplan-Meier estimate showed that proportions of women who were breastfeeding at 6, 9, 12 and 17 months were 89.3%, 75.3%, 66% and 17%, respectively. Those mothers having a monthly income of ≤500 ETB [AHR = 0.16, 95% CI :(0.03–0.76)], having a family size of three and below [AHR = 0.12, 95%CI: (0.02–0.68), four and above [AHR = 0.07, 95%CI: (0.01–0.35)] and bottle feeding [AHR = 3.95, 95%CI: (1.64–9.51)] were also independent factors associated with breastfeeding cessation.

Conclusion

Above one third of HIV positive mothers stopped breastfeeding before 12 months. Monthly income, bottle feeding and family size were the independent predictors of breastfeeding cessations. Strengthening the current counseling and promotion modality on avoidance of bottle feeding and continued breastfeeding is recommended for improved HIV free survival.

Commonalities and differences in infant feeding attitudes and practices in the context of HIV in sub-Saharan Africa: a metasynthesis

Exclusive breastfeeding (EBF) has been identified as a key intervention to promote infant health and to reduce the vertical transmission of HIV. Despite this knowledge and increased resources to promote EBF, the practice in sub-Saharan Africa (SSA) remains low among HIV+ women. Although a number of qualitative studies have been conducted throughout SSA, the influences on and consequences of infant feeding choices of HIV+ mothers' findings have not been regarded systematically. Therefore, our objective was to identify overarching themes, commonalities, and differences in infant feeding choices among qualitative studies with HIV+ mothers in SSA. Sixteen qualitative studies of infant feeding practices in the context of HIV were identified. Noblit and Hare's seven-step metasynthesis methodology was used to analyze the experiences of HIV+ women and those who provide infant feeding services/counseling. Data were available from approximately 920 participants (i.e., 750 HIV+ mothers, 109 health-care providers, and 62 family members) across 13 SSA countries from 2000 to 2011. From these data, five themes emerged within which 3-4 overarching key metaphors were identified. The consistency of key metaphors across a variety of geographic, economic, and cultural settings suggest the importance of approaching infant feeding holistically, within the context of maternal knowledge, health-care support, family resources, and cultural expectations. EBF campaigns in SSA are more likely to successfully support optimal health for infants and a safe supportive environment for their mothers when the impact of infant feeding decisions are evaluated across these themes.

The challenges of adherence to infant feeding choices in prevention of mother-to-child transmission of HIV infections in South East Nigeria

BACKGROUND

Global and national efforts in the 21st century are directed toward the elimination of new pediatric HIV infections through evidence-based infant feeding interventions for the prevention of mother-to-child-transmission, with patient preference, motivation, and adherence identified as key factors for success.

OBJECTIVES

This study assessed the challenges faced by HIV-infected parturients in adhering to the national infant feeding recommendations and their infant feeding preference for prevention of mother-to-child transmission in South East Nigeria.

METHODS

This is a cross-sectional, descriptive, questionnaire-based study of 556 parturients infected with HIV/AIDS.

RESULTS

The mean age of the participants was 28.0±5.3 years. The infant feeding choices were made jointly by both partners (61.1%) in the antepartum period. The HIV status disclosure rate was 89.2%. A large proportion (91.7%) practiced exclusive breastfeeding with highly active antiretroviral therapy, and 7.6% practiced mixed feeding because of nonadherence to their choice and national/international recommendations on infant feeding in the context of HIV/AIDS. This was mainly a result of pressure from family members (42.8%) and cultural practices (28.5%). Multivariate logistic regression analysis indicates that adherence was strongly associated with age, marital status, and employment status, but not with residence, educational status, or parity.

CONCLUSION

Exclusive breastfeeding is predominately the infant feeding choice among HIV-infected parturients in South East Nigeria, but there is still a gap between infant feeding preference and adherence to standard practice as a result of sociocultural challenges associated with risk for mixed feeding and the risk for mother-to-child-transmission of HIV by nursing mothers.

A phase I randomized clinical trial of candidate human immunodeficiency virus type 1 vaccine MVA.HIVA administered to Gambian infants

BACKGROUND

A vaccine to decrease transmission of human immunodeficiency virus type 1 (HIV-1) during breast-feeding would complement efforts to eliminate infant HIV-1 infection by antiretroviral therapy. Relative to adults, infants have distinct immune development, potentially high-risk of transmission when exposed to HIV-1 and rapid progression to AIDS when infected. To date, there have been only three published HIV-1 vaccine trials in infants.

TRIAL DESIGN

We conducted a randomized phase I clinical trial PedVacc 001 assessing the feasibility, safety and immunogenicity of a single dose of candidate vaccine MVA.HIVA administered intramuscularly to 20-week-old infants born to HIV-1-negative mothers in The Gambia.

METHODS

Infants were followed to 9 months of age with assessment of safety, immunogenicity and interference with Expanded Program on Immunization (EPI) vaccines. The trial is the first stage of developing more complex prime-boost vaccination strategies against breast milk transmission of HIV-1.

RESULTS

From March to October 2010, 48 infants (24 vaccine and 24 no-treatment) were enrolled with 100% retention. The MVA.HIVA vaccine was safe with no difference in adverse events between vaccinees and untreated infants. Two vaccine recipients (9%) and no controls had positive ex vivo interferon-γ ELISPOT assay responses. Antibody levels elicited to the EPI vaccines, which included diphtheria, tetanus, whole-cell pertussis, hepatitis B virus, Haemophilus influenzae type b and oral poliovirus, reached protective levels for the vast majority and were similar between the two arms.

CONCLUSIONS

A single low-dose of MVA.HIVA administered to 20-week-old infants in The Gambia was found to be safe and without interference with the induction of protective antibody levels by EPI vaccines, but did not alone induce sufficient HIV-1-specific responses. These data support the use of MVA carrying other transgenes as a boosting vector within more complex prime-boost vaccine strategies against transmission of HIV-1 and/or other infections in this age group.

Factors influencing infant-feeding choices selected by HIV-infected mothers: perspectives from Zimbabwe

AIM

To assess factors influencing infant-feeding methods selected by HIV-infected mothers.

METHODS

A descriptive quantitative study was conducted among 80 mothers with babies aged 0-6 months who were randomly selected and interviewed. Descriptive statistics were used to summarize the findings.

RESULTS

Factors considered by women in choosing the infant-feeding methods included sociocultural acceptability (58.8%), feasibility and support from significant others (35%), knowledge of the selected method (55%), affordability (61.2%), implementation of the infant-feeding method without interference (62.5%), and safety (47.5%). Exclusive breast-feeding was the most preferred method of infant feeding. Disclosure of HIV status by a woman to her partner is a major condition for successful replacement feeding method, especially within the African cultural context. However, disclosure of HIV status to the partner was feared by most women as only 16.2% of the women disclosed their HIV status to partners.

CONCLUSION

The factors considered by women in choosing the infant-feeding option were ability to implement the options without interference from significant others, affordability, and sociocultural acceptability. Knowledge of the selected option, its advantages and disadvantages, safety, and feasibility were also important factors. Nurses and midwives have to educate clients and support them in their choice of infant-feeding methods.

Barriers and promoters of home-based pasteurization of breastmilk among HIV-infected mothers in greater Dar es Salaam, Tanzania

BACKGROUND

For the past decade, heat-treating breastmilk has been an infant feeding option recommended by the World Health Organization as a strategy to reduce vertical transmission. However, little is known about field experiences with it. Our primary objective was to explore the barriers and promoters of the implementation of breastmilk pasteurization, "flash-heating" (FH), in the real-world setting of Dar es Salaam, Tanzania.

SUBJECTS AND METHODS

Nineteen in-depth interviews were conducted with participants in a home-based infant feeding counseling intervention in which FH was promoted after 6 months of exclusive breastfeeding. Additionally, three focus group discussions were conducted with peer counselors. Interviews were transcribed, translated, and coded independently using NVivo 8 software (QSR International). Data were analyzed using the socioecological framework.

RESULTS

Information and support provided by peer counselors were the most important promoters of initiation and continuation of FH; this impacted individual-, interpersonal-, and institutional-level promoters of success. Other promoters included perceived successful breastmilk expression, infant health after initiation of FH, and the inability to pay for replacement milks. Stigma was the most important barrier and cut across all levels of the framework. Other barriers included doubt about the safety or importance of pasteurized breastmilk, difficulties with expressing milk (often attributed to poor diet), and competing responsibilities. The most common suggestion for improving the uptake and duration of FH was community education.

CONCLUSIONS

Given the acknowledged role of breastmilk pasteurization in the prevention of vertical transmission, further implementation research is needed. A multilevel intervention addressing barriers to FH would likely improve uptake.

Translating Research into Practice in Low-Resource Countries: Progress in Prevention of Maternal to Child Transmission of HIV in Nigeria

Background. Research related to prevention of maternal to child transmission (PMTCT) of HIV is dynamic and rapidly changing and has provided evidence-based interventions and policies for practitioners. However, it is uncertain that research and policy guidelines are adequately being disseminated and implemented in resource-constrained countries with the largest burden PMTCT. This study examined current PMTCT practices in 27 public health facilities in Nigeria. Methods. A cross-sectional survey of 231 practicing nurses was conducted. Current PMTCT care practices were evaluated and compared to WHO and national PMTCT policy guidelines. Linear mixed models evaluated the association between PMTCT care practices and training in PMTCT. Results. Most nurses (80%) applied practices involving newborn prophylaxis; yet significant gaps in maternal intrapartum treatment and infant feeding practices were identified. PMTCT training explained 25% of the variance in the application of PMTCT care practices. Conclusion. Key PMTCT practices are not being adequately translated from research into practice. Researchers, policymakers, and clinicians could apply the study findings to address significant knowledge translation gaps in PMTCT. Strategies derived from an implementation science perspective are suggested as a means to improve the translation of PMTCT research into practice in Sub-Saharan African medical facilities.

Individual and Community Perspectives, Attitudes, and Practices to Mother-to-Child-Transmission and Infant Feeding among HIV-Positive Mothers in Sub-Saharan Africa: A Systematic Literature Review

OBJECTIVES

International guidelines on infant feeding for HIV- positive mothers promote Exclusive Replacement Feeding (ERF) (infant formula or animal milk) or exclusive breastfeeding (with no supplements of any kind). A mixed feeding pattern, where breastfeeding is combined with other milks, liquid foods or solids, has been shown to increase the risk of transmission of HIV and is strongly discouraged. However, little is known about the ability of women to adhere to recommended feeding strategies to prevent mother-to-child transmission (MTCT) of HIV from breast milk. The objective of this study was to assess the individual and community-level factors that affect perspectives, attitudes and practices of HIV-positive mothers on MTCT and infant feeding in sub-Saharan Africa as documented in peer-reviewed and grey literature.

METHODS

This work is based on an extensive review of peer-reviewed articles and grey literature from the period 2000-2012. The literature search was carried out using electronic databases like Medline Ovid, Google Scholar, PubMed and EBSCOhost. Both quantitative and qualitative studies written in English language on HIV and infant feeding with particular emphasis on Sub-Saharan Africa were included.

RESULTS

The review found low adherence to the chosen infant feeding method by HIV-positive mothers. The following factors emerged as influencing infant feeding decisions: cultural and social norms; economic conditions; inadequate counselling; and mother's level of education.

CONCLUSIONS AND PUBLIC HEALTH IMPLICATIONS

Unless local beliefs and customs surrounding infant feeding is understood by policy makers and program implementers, Prevention of Mother-to-Child Transmission (PMTCT) programs will only be partially successful in influencing feeding practices of HIV-positive women. Hence programs should provide affordable, acceptable, feasible, safe and sustainable feeding recommendations that do not erode strong cultural practices. Advice to HIV-positive mothers should be based on local conditions that are acceptable to the community.

Feasibility of using flash-heated breastmilk as an infant feeding option for HIV-exposed, uninfected infants after 6 months of age in urban Tanzania

OBJECTIVE

Heat-treating expressed breastmilk is recommended as an interim feeding strategy for HIV-exposed infants in resource-poor countries, but data on its feasibility are minimal. Flash-heating (FH) is a simple in-home technique for heating breastmilk that inactivates HIV although preserving its nutritional and anti-infective properties. Our primary objective was to determine, among HIV-infected mothers, the feasibility and protocol adherence of FH expressed breastmilk after 6 months of exclusive breastfeeding.

DESIGN

Prospective longitudinal.

PARTICIPANTS

One hundred one HIV-infected breastfeeding mothers.

SETTING

Dar es Salaam, Tanzania.

INTERVENTION

Peer counselors provided in-home counseling and support on infant feeding from 2 to 9 months postpartum. Mothers were encouraged to exclusively breastfeed for 6 months followed by FH expressed breastmilk if her infant was HIV negative. Clinic-based staff measured infant growth and morbidity monthly, and mothers kept daily logs of infant morbidity. FH behavior was tracked until 9 months postpartum using daily logs, in-home observations, and clinic-based and home-based surveys. Bacterial cultures of unheated and heated milk samples were performed.

RESULTS

Thirty-seven of 72 eligible mothers (51.4%) chose to flash-heat. Median (range) frequency of milk expression was 3 (1-6) times daily and duration of method use on-study was 9.7 (0.1-15.6) weeks. Mean (SD) daily milk volume was 322 (201) mL (range 25-1120). No heated and 32 (30.5%) unheated samples contained bacterial pathogens.

CONCLUSIONS

FH is a simple technology that many HIV-positive women can successfully use after exclusive breastfeeding to continue to provide the benefits of breastmilk while avoiding maternal-to-child transmission associated with nonexclusive breastfeeding. Based on these feasibility data, a clinical trial of the effects of FH breastmilk on infant health outcomes is warranted.
