Prevalence and Factors Associated with Chronic Energy Deficiency among Adolescent Girls and Young Mothers in Sub-Saharan Africa

Background Adolescent girls and young mothers (AGYM) have high nutritional needs, which puts them at risk of malnutrition. In particular, little is known about the prevalence and determinants of chronic energy deficiency (CED) of AGYM, which received less attention among researchers in sub-Saharan Africa. Objective The aim of the study was to examine the prevalence and associated factors of CED among AGYM in sub-Saharan Africa. Methods Data from the latest demographic and health surveys in four countries were used for this study: Gabon, Kenya, Malawi and Nigeria. Chronic energy deficiency, the outcome variable referred to as Body Mass Index (BMI), is classified as underweight for AGYM, whose BMI is less than 18.5kg/m2 according to the global standards established by the United Nations Children’s Fund (UNICEF) . Data analysis was done in three stages: descriptive, bivariate, and multivariable. Results The prevalence of chronic energy deficiency among AGYM was 7.2% in Malawi, 13.4% in Gabon, 14.9% in Kenya and 15.4% in Nigeria. The extent of chronic energy deficiency was particularly high among adolescent girls aged 15-19 in Gabon, AGYMs with no education in Nigeria and Kenya, and AGYMs from poor households in Nigeria, suggesting the necessity to provide systematic food rations to AGYMs of these specific groups. Finally, multivariable analysis shows that there are reduced odds of suffering from chronic energy deficiency among AGYM aged 20-24 years in Gabon and Kenya, compared with 15-19-year-olds. It is also revealed that education was negatively associated with chronic energy deficiency of AGYM in Nigeria and Kenya. Conclusion Mothers, particularly girls and young mothers, need more economic programmes to safeguard their reproductive rights through the promotion of nutritional information. This information is key for their nutritional protection, particularly for teenage girls (aged 15-19), the uneducated, and those living in poor households.

Effect of Fermentation Time and Blending Ratio on Microbial Dynamics, Nutritional Quality and Sensory Acceptability of Shameta: A Traditional Cereal-Based Fermented Porridge for Lactating Mothers in Ethiopia

Ethiopia has one of the highest levels of malnourished lactating mothers in sub-Saharan Africa. However, traditionally, different communities prepare foods solely for lactating mothers. For example, “Shameta” is one of the cereal-based fermented cultural foods exclusively produced for lactating mothers with the perception that it would support the health, increase the strength, and promote the recovery process of mothers after childbirth. This study investigated the effects of the fermentation time and blending ratio on the nutritional quality of “Shameta”. Three levels of blending ratio of ingredients (maize–barley–fava bean) and three levels of fermentation times were laid down in a completely randomized design (CRD). The study showed that lactic acid bacteria was the dominant group, followed by yeasts. Notably, the ingredient formulation ratio of Maize–barley–fava bean (81:5:5) had the highest LAB dominance with the highest crude fat (13.23 g/100g) content in all fermentation times (8, 10, and 12 days). However, the highest crude protein (16.56 g/100g) and mineral contents were observed in a ratio mix of 66:10:15 fermented for 12 days. The results of this study indicate that the nutritional quality of culturally prepared Shameta can be improved by optimizing the fermentation time and ingredient compositions for fast recovery, increased strength, and improved health of lactating mothers.

In their own words: linguistic analysis of interviews with Sesotho mothers on their child’s first thousand days

ABSTRACT Sensitive and responsive caregiving is a critical protective factor for children in Sub-Saharan Africa (SSA) during their first 1000 days of life. Health initiatives may benefit from evaluating the experience of caregivers in SSA to understand their parenting experiences. This study utilized linguistic analysis to gain insight into the lived experience of 19 Sesotho-speaking mothers of infants aged 18–30 months in low-income areas of Mangaung, Free State, South Africa. Women were asked the same set of questions about their child’s first 1000 days of life, and we used LIWC (Linguistic Inquiry and Word Count) LIWC to evaluate the perspectives of mothers in SA compared to published LIWC norms. Analyses revealed word use patterns associated with psychological processes such as negative affect, social processes, anger and anxiety. Findings are discussed within the context of Sesotho culture to aid in the future intervention development for this vulnerable population. This study is important because it yields important information about the subjective experience of an understudied critical population of mothers in SSA. Further, this study points to future directions for the field of understanding the impact of motherhood on women in low resource settings.

Comparing adverse maternal and neonatal outcomes in adolescent versus adult mothers in Sub-Saharan Africa.

Adolescent pregnancy is a major social and public health problem that burdens affected families, the communities and societies globally. It has been associated with a higher prevalence of adverse pregnancy outcomes compared to pregnancy in adults. To compare adverse pregnancy outcomes in adolescents (13-19 years) and those in adults (20 to 35 years) at the Korle-Bu Teaching Hospital in Accra, Ghana and investigate the associated factors among adolescents. This comparative study involved 110 adolescents (13-19 years) and 220 adults (20 to 35 years) who delivered at the Maternity Unit of the Korle-Bu Teaching Hospital between November 2016 and February 2017. Participants were recruited using the convenience sampling method. After study protocol was explained to the parturient, informed voluntary consent and assent were obtained. Participants who met the inclusion criteria were recruited in the study. Sociodemographic characteristics, antenatal and delivery records; and maternal and perinatal outcomes were collected using an interviewer administered questionnaire and the participants' records. Data analysis was done using SPSS version 16.0. The prevalence of adolescent pregnancies during the study period was 5.1%. Compared to adults, adolescents were about 3 times more likely to have eclampsia although preeclampsia occurred more in adults. Adolescents that resided in sub-urban dwellings were more likely to have an adverse perinatal outcome compared to their adult counterparts. Our study found that, in addition to their socioeconomic and biophysical disadvantages, adolescents were likely to have exceptionally high risk of eclampsia.

Preventing Perinatal Depression: Cultural Adaptation of the Mothers and Babies Course in Kenya and Tanzania.

Pregnant women and mothers in sub-Saharan Africa are at high risk for perinatal depression, warranting a need to develop culturally tailored interventions to prevent perinatal depression. This paper documents the process of adapting an evidence-based preventive intervention developed in the United States, the Mothers and Babies Course (MBC), to fit the contexts of rural pregnant women and mothers of young children in Kenya and Tanzania using the updated Framework for Reporting Adaptations and Modifications-Enhanced (FRAME). Data from informant interviews and field observations from the planning and implementation phases were used to make adaptations and modifications of the MBC for perinatal women through the eight aspects of FRAME. Follow-up field visits and reflection meetings with case managers and intervention participants indicated that the adapted version of the MBC was well accepted, but fidelity was limited due to various implementation barriers. The FRAME provided an optimal structure to outline the key adaptations and modifications of a preventive intervention intended to maximize engagement, delivery, and outcomes for high-risk perinatal women in rural settings.

Genetic studies on iron and zinc concentrations in common bean (Phaseolus vulgaris L.) in Ghana

Iron and zinc deficiencies cause high health risk to young children and expectant mothers in sub Saharan Africa. The development of biofortified common bean (Phaseolus vulgaris L.) varieties could address the acute micronutrient deficiencies with associated improvement in the nutrition and health of women, children and adults. The objective of this study was to determine the mode of gene action and genetic advance in iron and zinc levels in common bean. Field experiment was carried out using six generations of two populations made of crosses between pairs of low iron, low zinc and high iron, moderate zinc genotypes (Cal 96 ˣ RWR 2154; MCR-ISD-672 ˣ RWR 2154). Each generation (P1, P2, F1, F2, BC1P1 and BC1P2) was evaluated on the field in a randomized complete block design with three replications. Generation mean analysis were performed for each trait measured in each of the crosses while iron and zinc levels were quantified by x-ray fluorescence. The study showed that both additive and non-additive gene effects were important in determining the expression of high iron and zinc levels. Iron concentration in the common bean seeds ranged from 60.68 to 101.66ppm while zinc levels ranged from 25.87 to 34.04ppm. Broad sense heritability estimates of iron and zinc were high in the two crosses (62-82% for Fe and 60-74% for Zn) while narrow sense heritability ranged from low to high (53-75% for Fe and 21-46% for Zn). Heritability and genetic gain were used as selection criteria for iron and zinc, and it was concluded that doing so would be beneficial for future improvement.

Risk of early horizontal transmission of hepatitis B virus in children of uninfected mothers in sub-Saharan Africa: a systematic review and meta-analysis

Sub-Saharan Africa is highly endemic for hepatitis B virus (HBV); historically, most people were exposed during childhood through vertical or horizontal transmission. Although all African countries now provide a three-dose infant hepatitis B vaccination starting at age 6-8 weeks, only a third of African countries have introduced birth dose (HepB-BD) vaccine. Adding HepB-BD is fundamental to prevent vertical transmission, but its effectiveness in preventing horizontal transmission, compared with the three-dose infant vaccination alone, is unknown. We aimed to estimate the risk of early horizontal transmission in children of hepatitis B surface antigen (HBsAg)-negative mothers in sub-Saharan Africa stratified according to the vaccination schedule. In this systematic review and meta-analysis we searched MEDLINE, Global Health, Embase, African Index Medicus and African Journals Online from their inception to Oct 24, 2022, for studies reporting HBsAg or HBV DNA, or both, in children (aged 0-5 years) of HBsAg-negative mothers. We excluded studies if children were only tested at birth. Two reviewers independently screened the titles and abstracts of all articles and data were extracted using a standardised pre-piloted data extraction sheet, and authors were contacted if any important information was missing. The primary outcome was the risk of HBV infection in children of HBsAg-negative mothers, stratified by vaccination schedule (no vaccination, first dose at 6-8 weeks, or first dose at birth). We pooled the child risks of HBsAg or HBV DNA-positivity from the age of 0 years to 5 years via a random-effect meta-analysis using a generalised linear mixed model. The study was registered on PROSPERO, CRD42021236203. Of 8856 articles identified, 27 studies evaluating 10 003 children of HBsAg-negative mothers were included. The pooled risks of infection were 6·16% (95% CI 3·05-12·04; 155/1407) in the no vaccination group, 0·21% (0·04-1·15; 10/3425) in children who received their first dose at 6-8 weeks, and 0·05% (0·00-1·32; 3/2902) in children who received their first dose at birth. The difference was not statistically significant in children who received their first dose at 6-8 weeks and children who received their first dose at birth after adjusting for the study period, region, and maternal HIV status (test of moderators p=0·37). In children of HBsAg-negative mothers, the risk of infection might be minimal even with the vaccination starting at 6-8 weeks, without clear additional benefit from HepB-BD. When births take place at home and timely administration of HepB-BD is challenging, antenatal HBsAg screening and selective HepB-BD might allow efficient allocation of resources to mother and child pairs at high risk compared with universal HepB-BD. None. For the French translation of the abstract see Supplementary Materials section.

Suitability of testers to characterize provitamin a content and agronomic performance of tropical maize inbred lines.

Vitamin A deficiency poses health risks for children, pregnant women, and nursing mothers in sub-Saharan Africa (SSA) and Southeast Asia. Provitamin A–biofortified maize varieties can contribute to minimizing the adverse effects of vitamin A deficiency in areas where maize is a staple food crop. Identifying suitable testers is important to breed provitamin A–biofortified hybrid maize. This study was therefore conducted to 1) assess the suitability of maize inbred lines with contrasting levels of provitamin A (one with high and one with low provitamin A concentration) to assess the combining ability of maize inbred lines in accumulating provitamin A and other carotenoids, and grain yield, 2) confirm the mode of inheritance of provitamin A and grain yield, and 3) identify promising inbred lines with desirable combining ability effects for use to develop high-yielding provitamin A–biofortified hybrids. The inbreds crossed to the two inbred testers were evaluated in four environments for the carotenoid content and eight environments for the agronomic performance. The combined analysis of variance revealed a significant genetic variation among the testcrosses for all carotenoids, grain yield, and other agronomic traits. The mode of inheritance for grain yield, other agronomic traits, provitamin A, and other carotenoids was regulated by both additive and non-additive gene effects with a prominence of additive gene effects. The high provitamin A tester that displayed positive GCA effects for β-carotene and provitamin A content, broader agronomic performance of testcrosses, and higher levels of provitamin A in testcrosses can be considered suitable for breeding programs developing provitamin A–biofortified hybrids. The inbred lines TZI2012, TZI2142, TZI2130, TZI2065-2, TZI2161, TZI2025, TZI1278, TZI1314, TZI1304, and TZI2032 with positive GCA effects for grain yield and provitamin A content could be used as parental lines to develop source population of new inbred lines and high-yielding hybrids with elevated levels of provitamin A. The best performing hybrids are promising for release as high-yielding provitamin A maize hybrids after further evaluations.

Sero-prevalence of human immunodeficiency virus\u2013hepatitis B virus (HIV\u2013HBV) co-infection among pregnant women attending antenatal care (ANC) in sub-Saharan Africa (SSA) and the associated risk factors: a systematic review and meta-analysis

BackgroundThere is plenitude of information on HIV infection among pregnant mothers attending antenatal care (ANC) in sub-Saharan Africa. However, the epidemiology of HBV–HIV co-infections in the same cohort is not clear despite the common route of transmission of both viruses. The aim of our study was to synthesize data on the prevalence of HBV–HIV co-infection among pregnant women attending ANC in Sub-Saharan Africa to assist in the design of public health interventions to mitigate the challenge.MethodsThe study was done in tandem with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards and the Cochran’s Q test, I2 statistics for heterogeneity and the prevalence were calculated using commercially available software called MedCalcs (https://www.medcalc.org). A random effect model was used to pool the prevalence since all the heterogeneities were high (≥ 78%) and Phet < 0.05 indicated significant heterogeneities. The risk factors and risk differences for HBV–HIV co-infection were analyzed. Any likely sources of heterogeneity were analyzed through sensitivity analysis, meta-regression and sub-group analysis. All analyses were done at 95% level of significance and a P < 0.05 was considered significant.ResultsThe overall pooled prevalence of HBV–HIV co-infection among pregnant mothers in sub-Saharan Africa was low 3.302% (95%CI = 2.285 to 4.4498%) with heterogeneities (I2) of 97.59% (P > 0.0001). Within regional sub group meta-analyses, West Africa had significantly higher prevalence of 5.155% (95% = 2.671 to 8.392%) with heterogeneity (I2) of 92.25% (P < 0.0001) than any other region (P < 0.001). Articles published from 2004–2010 had significantly higher prevalence of 6.356% (95% = 3.611 to 9.811%) with heterogeneity (I2) 91.15% (P < 0.0001) compared to those published from 2011 to 2019 (P < 0.001). The HIV positive cohort had significantly higher prevalence of HBV–HIV co-infection of 8.312% (95% CI = 5.806 to 11.22%) with heterogeneity (I2)94.90% (P < 0.0001) than the mothers sampled from the general population with a prevalence of 2.152% (95% CI = 1.358 to 3.125%) (P < 0.001). The overall and sub group analyses had high heterogeneities (I2 > 89%, P < 0.0001) but was reduced for South Africa (I2) = 78.4% (P = 0.0314). Age, marital status and employment were independent factors significantly associated with risk of HBV–HIV co-infection (P < 0.001) but not extent of gravidity and education level (P > 0.05). After meta-regression for year of publication and sample size for HBsAg positivity, the results were not significantly associated with HBV pooled prevalence for sample size (P = 0.146) and year of publication (P = 0.560). Following sensitivity analysis, the HBsAg pooled prevalence slightly increased to 3.429% (95% CI = 2.459 to 4.554%) with heterogeneity I2 = 96.59% (95% CI = 95.93 to 97.14%), P < 0.0001ConclusionThere is an urgent need for routine HBV screening among HIV positive pregnant mothers attending antenatal care in sub-Saharan Africa to establish the extent of HBV–HIV co-infection in this cohort. Future studies need to investigate the putative risk factors for HBV–HIV co-infection and prioritize plausible control strategies.

Stigma toward small babies and their mothers in Ghana: A study of the experiences of postpartum women living with HIV.

Infants born to HIV-infected mothers are more likely to be low birthweight (LBW) than other infants, a condition that is stigmatized in many settings worldwide, including sub-Saharan Africa. Few studies have characterized the social-cultural context and response to LBW stigma among mothers in sub-Saharan Africa or explored the views of women living with HIV (WLHIV) on the causes of LBW. We purposively sampled thirty postpartum WLHIV, who had given birth to either LBW or normal birthweight infants, from two tertiary hospitals in Accra, Ghana. Using semi-structured interviews, we explored women’s understanding of the etiology of LBW, and their experiences of caring for a LBW infant. Interviews were analyzed using interpretive phenomenology. Mothers assessed their babies' smallness based on the baby's size, not hospital-recorded birthweight. Several participants explained that severe depression and a loss of appetite, linked to stigma following an HIV diagnosis during pregnancy, contributed to infants being born LBW. Women with small babies also experienced stigma due to the newborns' "undesirable" physical features and other people's unfamiliarity with their size. Consequently, mothers experienced blame, reluctance showing the baby to others, and social gossip. As a result of this stigma, women reported self-isolation and depressive symptoms. These experiences were layered on the burden of healthcare and infant feeding costs for LBW infants. LBW stigma appeared to attenuate with increased infant weight gain. A few of the women also did not breastfeed because they thought their baby's small size indicated pediatric HIV infection. Among WLHIV in urban areas in Ghana, mother and LBW infants may experience LBW-related stigma. A multi-component intervention that includes reducing LBW incidence, treating antenatal depression, providing psychosocial support after a LBW birth, and increasing LBW infants’ weight gain are critically needed.

Non-uptake of childhood vaccination among the children of HIV-infected mothers in sub-Saharan Africa: A multilevel analysis

ABSTRACTThe aim of this study was to develop and test models for non–uptake of three doses of diphtheria-tetanus-pertussis containing vaccines (DTP3) among children of women living with HIV in sub-Saharan Africa. The study used demographic and health survey data from 27 sub-Saharan African countries that have the required HIV and immunization data sets. Multivariable logistic regression models were used to assess the relationship between individual and contextual factors associated with non-uptake of DTP3 among the children. At the individual level, the odds of non-uptake of DTP3 decreased with formal education, increasing age and access to media. The full model shows that the odds of non-uptake of DTP3 is increased among unemployed women, those living in communities with high illiteracy rate and in countries with low adult literacy level. For a child who moved to another country or community with a higher probability of DTP3 non-uptake, the median increase for the odds of DTP3 non-uptake would be 2.24% and 1.22% respectively for country and community. This study shows that individual and contextual factors contributed significantly to non-uptake of DTP3 among the children of women living with HIV. Interventions should be focused on women living with HIV who are young mothers, unemployed women, those without formal education, individuals living in communities with high illiteracy rate and in countries with low adult literacy rate. The use of mass media tools and creation of more employment opportunities for HIV-infected women could improve vaccination coverage among their children.

Mind the Gap: What explains the education-related inequality in missed opportunities for vaccination in sub-Saharan Africa? Compositional and structural characteristics

ABSTRACTMissed opportunities for vaccination (MOV) is an important barrier hindering full immunisation coverage among eligible children. Though factors responsible for MOV are well documented in literature, little attention has been paid to the role of inequalities. The aim of this study is to examine the association between structural or compositional factors and education inequalities in MOV. Blinder-Oaxaca decomposition technique was used to explain the factors contributing to the average gap in missed opportunities for vaccination between uneducated and educated mothers in sub-Saharan Africa using DHS survey data from 35 sub Saharan African countries collected between 2007 and 2016. The sample contained 69,657 children aged 12 to 23 months. We observed a wide variation and inter-country differences in the prevalence of missed opportunity for vaccination across populations and geographical locations. Our results show that the prevalence of MOV in Zimbabwe among uneducated and educated mothers was 9% and 21% respectively while in Gabon corresponding numbers were 85% and 89% respectively. In 15 countries, MOV was significantly prevalent among children born to uneducated mothers (pro-illiterate inequality) while in 5 countries MOV was significantly prevalent among educated mothers (pro-educated inequality). Our results suggest that education-related inequalities in missed opportunities for vaccination are explained by compositional and structural characteristics; and that neighbourhood socio-economic status was the most important contributor to education-related inequalities across countries followed by either the presence of under-five children, media access or household wealth index. The results showed that differential effects such as neighbourhood socio-economic status, presence of under-five children, media access and household wealth index, primarily explained education-related inequality in MOV. Interventions to reduce gaps in education-related inequality in MOV should focus on social determinants of health.

Risk factors for prelacteal feeding in sub-Saharan Africa: a multilevel analysis of population data from twenty-two countries.

To examine the risk factors of prelacteal feeding (PLF) among mothers in sub-Saharan Africa (SSA). We pooled data from Demographic and Health Surveys in twenty-two SSA countries. The key outcome variable was PLF. A multilevel logistic regression model was used to explore factors associated with PLF. Demographic and Health Surveys in twenty-two SSA countries. Mother-baby pairs (n 95348). Prevalence of PLF in SSA was 32·2 %. Plain water (22·1 %), milk other than breast milk (5·0 %) and sugar or glucose water (4·1 %) were the predominant prelacteal feeds. In the multivariable analysis, mothers who had caesarean section delivery had 2·25 times the odds of giving prelacteal feeds compared with mothers who had spontaneous vaginal delivery (adjusted OR=2·25; 95 % CI 2·06, 2·46). Other factors that were significantly associated with increased likelihood of PLF were mother's lower educational status, first birth rank, fourth or above birth rank with preceding birth interval less than or equal to 24 months, lower number of antenatal care visits, home delivery, multiple birth, male infant, as well as having an average or small sized baby at birth. Mothers aged 20-34 years were less likely to give prelacteal feeds compared with mothers aged ≤19 years. Belonging to the second, middle or fourth wealth quintile was associated with lower likelihood of PLF compared with the highest quintile. To achieve optimal breast-feeding, there is a need to discourage breast-feeding practices such as PLF. Breast-feeding promotion programmes should target the at-risk sub-population groups discovered in our study.

The World Health Organization (WHO) recommends exclusive breast-feeding (EBF) for HIV exposed infants for six months; this is considered best practice for reducing mother-to-child transmission of HIV in the postpartum period. This is a scoping review of the barriers affecting women&#39;s decision-making and choice to sustain the practice of EBF in sub-Saharan Africa (SSA). An online literature search via PubMed, Science Direct, Google Scholar, WHO and Joint United Nations Programme on HIV and AIDS (UNAIDS) websites identified research studies and reports that explored socio-economic, cultural and infant feeding counselling-related barriers to EBF among HIV-positive mothers in SSA. A total of 341 relevant articles were identified only 35 (23 qualitative, 3 quantitative and 9 mixed methods) met the inclusion criteria. Findings reveal that key barriers to choice and sustained practice of EBF are healthcare workers&rsquo; personal biases, inadequate counselling skills and guideline knowledge, a culture of mixed feeding norms, and maternal lack of decision-making power and fear of vertical transmission. Transmission of HIV programs in countries where major challenges persist should evaluate and address the identified healthcare worker and community-level factors impeding EBF. Key words: Africa South of the Sahara, breastfeeding, counselling, cultural norms, socioeconomic, HIV seropositivity, mothers.

Increased Cytomegalovirus Secretion and Risks of Infant Infection by Breastfeeding Duration From Maternal Human Immunodeficiency Virus Positive Compared to Negative Mothers in Sub-Saharan Africa.

BackgroundBreastfeeding imparts beneficial immune protection and nutrition to infants for healthy growth, but it is also a route for human immunodeficiency virus (HIV) and human cytomegalovirus (HCMV) infection. In previous studies, we showed that HCMV adversely affects infant development in Africa, particularly with maternal HIV exposure. In this study, we analyzed infants risks for acquisition of HCMV infection from breastfeeding and compared HIV-positive and HIV-negative mothers.MethodsTwo cohorts were studied in Zambia. (1) Two hundred sixty-one HIV-infected and HIV-uninfected mothers were compared for HCMV deoxyribonucleic acid (DNA) loads and genotypes (glycoprotein gO) in milk from birth to 4 months postpartum. (2) Maternally HIV-exposed and HIV-unexposed infants were compared for HCMV infection risk factors. The second cohort of 460 infants, from a trial of micronutrient-fortified complementary-food to breastfeeding, were studied between 6 and 18 months of age. Human cytomegalovirus seroprevalence was assayed, and logistic regression was used to calculate risk factors for HCMV infection, including maternal HIV exposure and breastfeeding duration.ResultsHuman cytomegalovirus was detected in breast milk from 3 days to 4 months postpartum, with significantly raised levels in HIV-positive women and independent of genotype. In infants, HCMV antibody seroprevalence was 83% by 18 months age. Longer breastfeeding duration increased infection risk in maternally HIV-unexposed (odds ratio [OR] = 2.69 for 18 months vs <12 months; 95% confidence interval [CI], 0.84–8.59; P = .03) and HIV-exposed infants (OR = 20.37 for >6 months vs never; 95% CI, 3.71–111.70; P < .001).ConclusionsProlonged breastfeeding, which is common in Africa, increased risk of HCMV infection in infants. Both HIV-positive and HIV-negative women had extended milk HCMV secretion. Women who were HIV-positive secreted higher HCMV levels, and for longer duration, with their children at increased infection risk. Human cytomegalovirus control is required to maintain health benefits of breastfeeding.

High Rates of Exclusive Breastfeeding in Both Arms of a Peer Counseling Study Promoting EBF Among HIV-Infected Kenyan Women.

Exclusive breastfeeding (EBF) is recommended for 6 months after delivery as the optimal infant feeding method and is especially important for prevention of mother-to-child HIV transmission (PMTCT). However, EBF promotion efforts among HIV-infected mothers in sub-Saharan Africa have achieved mixed success and require context-specific interventions. HIV-positive, pregnant women from six clinics in Nairobi were enrolled into a clinic-level, before-after counseling intervention study. All women received standard perinatal and HIV care. Women in the intervention arm were offered three counseling sessions that promoted EBF, described its benefits, and explained breastfeeding techniques. Mother-infant pairs were followed until 14 weeks postpartum, with infant HIV testing at 6 weeks. EBF prevalence at 14 weeks postpartum was compared between study arms using log-binomial regression. Proportions of 6-week HIV-free survival and 14-week infant survival were assessed using Cox regression. Risk estimates were adjusted for clinic, relationship status, and antiretroviral therapy. Between 2009 and 2013, 833 women were enrolled of whom 94% planned to practice EBF for 6 months and 95% were taking therapeutic or prophylactic antiretrovirals. Median age was 27 years; median CD4 count was 403 cells/μL. EBF prevalence at 14 weeks postpartum was 86% in the control and 81% in the intervention group (p = 0.19). No differences were observed between groups for 6-week HIV-free survival and 14-week infant survival. Women who received breastfeeding counseling were not more likely to breastfeed exclusively, in part due to high overall EBF prevalence in this study population. The high EBF prevalence is an important finding, given recent efforts to promote EBF in Kenya.

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

Appropriate infant feeding is a persistent challenge for human immunodeficiency virus (HIV)-infected mothers in sub-Saharan Africa. This study aimed to describe correlates of infant feeding among HIV-infected mothers in coastal Tanzania. 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. 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. 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.

Health care-seeking behaviour of HIV-infected mothers and male partners in Nairobi, Kenya

Health care-seeking behaviours of HIV-infected mothers in sub-Saharan Africa are poorly characterised and typically focus on individual health conditions rather than overall health. We conducted a qualitative study to understand how HIV-infected mothers, their male partners and their HIV-exposed infants seek medical services. We performed 32 in-depth interviews (17 female, 15 male) and four focus group discussions among HIV-infected post-partum women and their male partners in Nairobi, Kenya. We used a grounded theory approach to explore the paths followed for health-related concerns. Female participants reported that willingness to be tested for HIV influences whether women sought antenatal care and the type of facility they preferred for childbirth. The need for medical care outside regular clinic hours and securing safe transportation at night were also significant barriers to seeking care.
