HIV status, breastfeeding modality at 5 months and postpartum maternal weight changes over 24 months in rural South Africa

ObjectiveTo determine the effect of infant feeding practices on postpartum weight change among HIV-infected and -uninfected women in South Africa.MethodsIn a non-randomised intervention cohort study of antiretroviral therapy-naïve women in South Africa, infants were classified as exclusive (EBF), mixed (MF) or non-breastfed (NBF) at each visit. We analysed infant feeding cumulatively from birth to 5 months using 24-hour feeding history (collected weekly for each of the preceding 7 days). Using generalised estimating equation mixed models, allowing for repeated measures, we compared postpartum weight change (kg) from the first maternal postpartum weight within the first 6 weeks (baseline weight) to each subsequent visit through 24 months among 2340 HIV-infected and -uninfected women with live births and at least two postpartum weight measurements.ResultsHIV-infected (?0.2 kg CI: ?1.7 to 1.3 kg; P = 0.81) and -uninfected women (?0.5 kg; 95% CI: ?2.1 to 1.2 kg; P = 0.58) had marginal non-significant weight loss from baseline to 24 months postpartum. Adjusting for HIV status, socio-demographic, pregnancy-related and infant factors, 5-month feeding modality was not significantly associated with postpartum weight change: weight change by 24 months postpartum, compared to the change in the reference EBF group, was 0.03 kg in NBF (95% CI: ?2.5 to +2.5 kg; P = 0.90) and 0.1 kg in MF (95% CI: ?3.0 to +3.2 kg; P = 0.78).ConclusionHIV-infected and -uninfected women experienced similar weight loss over 24 months. Weight change postpartum was not associated with 5-month breastfeeding modality among HIV-infected and -uninfected women.ObjectifDéterminer l'effet des pratiques d'alimentation des nourrissons sur la variation du poids postpartum chez les femmes infectées et non infectées par le VIH en Afrique du Sud.MéthodesDans une étude de cohorte d'intervention non randomisée sur la thérapie aux antirétroviraux, les nourrissons de femmes naïves pour le traitement en Afrique du Sud, ont été classés comme allaités exclusivement au sein (EBF), recevant une alimentation mixte (MF) ou non allaités au sein (NBF), à chaque visite. Nous avons analysé l'alimentation du nourrisson cumulativement de la naissance à cinq mois, en utilisant l'historique de l'alimentation sur 24 heures (recueillies hebdomadairement pour chacun des sept jours précédents). En utilisant l’équation d'estimation des modèles mixtes généralisés, permettant des mesures répétées, nous avons comparé les changements de poids (kg) postpartum de la première mesure du poids postpartum de la mère endéans les six premières semaines (poids de base) au poids à chaque visite subséquente durant 24 mois chez 2340 femmes infectées et non infectées par le VIH, ayant eu des naissances vivantes et au moins deux mesures du poids postpartum.RésultatsLa perte de poids des femmes infectées (-0,2 kg; IC: -1,7 à 1,3 kg; P = 0,81) et non infectées (0,5 kg, IC95%: -2,1 à 1,2 kg; P = 0,58) par le VIH était marginalement non significative de la base à 24 mois postpartum. En ajustant pour le statut VIH et sociodémographique, pour les facteurs liés à la grossesse et infantiles, le mode d'alimentation sur cinq mois n’étaient pas significativement associé à la variation du poids postpartum; la variation de poids sur 24 mois postpartum comparée à celle dans le groupe EBF de référence, était de 0,03 kg chez les NBF (IC95%: -2,5 à 2,5 kg; P = 0,90) et 0,1 kg chez les MF (IC95%: -3,0 à 3,2 kg; P = 0,78).ConclusionLes femmes infectées et non infectées par le VIH connaissent une perte de poids similaire sur 24 mois. La variation du poids postpartum n'a pas été associée au mode d'allaitement à cinq mois chez les femmes infectées et non infectées par le VIH.ObjetivoDeterminar el efecto de las prácticas de alimentación de los bebés en la variación del peso materno postparto entre mujeres infectadas y no infectadas con VIH en Sudáfrica.MétodosEn una intervención en Sudáfrica no aleatorizada, dentro de un estudio de cohortes de mujeres que no habían recibido anteriormente terapia antirretroviral (naive) – los bebés de se clasificaron como recibiendo exclusivamente el pecho (EP), alimentación mixta (AM), o que no eran amamantados (NA) en cada visita. Hemos analizado la alimentación acumulativa del bebé, desde el nacimiento hasta los cinco meses de edad, utilizando un historial de alimentación de 24 horas (recogido semanalmente para los 7 días anteriores). Utilizando modelos mixtos de ecuaciones de estimación generalizadas, permitiendo medidas repetidas, hemos comparado el cambio de peso (kg) durante el postparto - desde la primera pesada dentro de las primeras seis semanas postparto (peso inicial) con cada visita subsiguiente, durante los 24 meses posteriores, para 2340 mujeres - infectadas con VIH y sin infectar – que dieron a luz bebés nacidos vivos y que tenían recogidas al menos dos pesadas postparto.ResultadosLas mujeres infectadas con VIH (-0.2 kg IC: -1.7 – 1.3 kg; P = 0.81) y aquellas no infectadas (-0.5kg; 95% IC: -2.1 – 1.2 kg; P =0.58) tenían una pérdida de peso marginal y no significativa entre el comienzo del estudio hasta los 24 meses después del parto. Ajustando para el estatus de VIH, los factores sociodemográficos y relacionados con el embarazo y el bebé, la modalidad de alimentación del bebé durante sus cinco primeros meses no estaba significativamente asociada con el cambio de peso postparto: el cambio de peso 24 meses después del parto, comparada con el cambio en referencia al grupo EP, era de 0.03 kg en NA (IC 95%: -2.5 – +2.5 kg; P = 0.90) y 0.1 kg en AM (IC 95%: -3.0 – +3.2 kg; P = 0.78).ConclusiónLas mujeres infectadas con VIH y aquellas sin infección experimentaron una pérdida de peso similar en los 24 meses postparto. El cambio de peso no estaba asociado con la modalidad de amamantamiento entre las mujeres VIH positivas y VIH negativas

The Amagugu intervention: a conceptual framework for increasing HIV disclosure and parent-led communication about health among HIV-Infected parents with HIV-uninfected primary school-aged children

Advances in access to HIV prevention and treatment have reduced vertical transmission of HIV, with most children born to HIV-infected parents being HIV-uninfected themselves. A major challenge that HIV-infected parents face is disclosure of their HIV status to their predominantly HIV-uninfected children. Their children enter middle childhood and early adolescence facing many challenges associated with parental illness and hospitalization, often exacerbated by stigma and a lack of access to health education and support. Increasingly, evidence suggests that primary school-aged children have the developmental capacity to grasp concepts of health and illness, including HIV, and that in the absence of parent-led communication and education about these issues, HIV-exposed children may be at increased risk of psychological and social problems. The Amagugu intervention is a six-session home-based intervention, delivered by lay counselors, which aims to increase parenting capacity to disclose their HIV status and offer health education to their primary school-aged children. The intervention includes information and activities on disclosure, health care engagement, and custody planning. An uncontrolled pre–post-evaluation study with 281 families showed that the intervention was feasible, acceptable, and effective in increasing maternal disclosure. The aim of this paper is to describe the conceptual model of the Amagugu intervention, as developed post-evaluation, showing the proposed pathways of risk that Amagugu aims to disrupt through its intervention targets, mechanisms, and activities; and to present a summary of results from the large-scale evaluation study of Amagugu to demonstrate the acceptability and feasibility of the intervention model. This relatively low-intensity home-based intervention led to: increased HIV disclosure to children, improvements in mental health for mother and child, and improved health care engagement and custody planning for the child. The intervention model demonstrates the potential for disclosure interventions to include pre-adolescent HIV education and prevention for primary school-aged children

Communication about HIV and death: Maternal reports of primary school-aged children's questions after maternal HIV disclosure in rural South Africa

Introduction: Children's understanding of HIV and death in epidemic regions is under-researched. We investigated children's death-related questions post maternal HIV-disclosure. Secondary aims examined characteristics associated with death-related questions and consequences for children's mental health. Methods: HIV-infected mothers (N = 281) were supported to disclose their HIV status to their children (6–10 years) in an uncontrolled pre-post intervention evaluation. Children's questions post-disclosure were collected by maternal report, 1–2 weeks post-disclosure. 61/281 children asked 88 death-related questions, which were analysed qualitatively. Logistic regression analyses examined characteristics associated with death-related questions. Using the parent-report Child Behaviour Checklist (CBCL), linear regression analysis examined differences in total CBCL problems by group, controlling for baseline. Results: Children's questions were grouped into three themes: ‘threats’; ‘implications’ and ‘clarifications’. Children were most concerned about the threat of death, mother's survival, and prior family deaths. In multivariate analysis variables significantly associated with asking death-related questions included an absence of regular remittance to the mother (AOR 0.25 [CI 0.10, 0.59] p = 0.002), mother reporting the child's initial reaction to disclosure being “frightened” (AOR 6.57 [CI 2.75, 15.70] p=<0.001) and level of disclosure (full/partial) to the child (AOR 2.55 [CI 1.28, 5.06] p = 0.008). Controlling for significant variables and baseline, all children showed improvements on the CBCL post-intervention; with no significant differences on total problems scores post-intervention (β -0.096 SE1.366 t = -0.07 p = 0.944). Discussion: The content of questions children asked following disclosure indicate some understanding of HIV and, for almost a third of children, its potential consequence for parental death. Level of maternal disclosure and stability of financial support to the family may facilitate or inhibit discussions about death post-disclosure. Communication about death did not have immediate negative consequences on child behaviour according to maternal report. Conclusion: In sub-Saharan Africa, given exposure to death at young ages, meeting children's informational needs could increase their resilience

Health impact of catch-up growth in low-birth weight infants : systematic review, evidence appraisal, and meta-anaylsis

This study aimed to systematically review and appraise evidence on the short-term (e.g. morbidity, mortality) and long-term (obesity and non-communicable diseases, NCDs) health consequences of catch-up growth (versus no catch-up growth) in individuals with a history of low birth weight (LBW).We searched MEDLINE, EMBASE, Global Health, CINAHL plus, Cochrane Library, ProQuest Dissertations and Thesis, and reference lists. Study quality was assessed using the risk of bias assessment tool from the Agency for Health Care Research and Quality, and the evidence base was assessed using the GRADE tool. Eight studies in 7 cohorts (2 from high-income countries, 5 from low-middle income countries) met the inclusion criteria for short-term (mean age: 13.4 months) and/or longer-term (mean age: 11.1 years) health outcomes of catch-up growth which had occurred by 24 or 59 months. Of 5 studies on short-term health outcomes, 3 found positive associations between weight catch-up growth and body mass and/or glucose metabolism; 1 suggested reduced risk of hospitalisation and mortality with catch-up growth. Three studies on longer-term health outcomes found catch-up growth was associated with higher body mass, BMI, or cholesterol. GRADE assessment suggested that evidence quantity and quality were low. Catch-up growth following LBW may have benefits for the individual with LBW in the short term, and may have adverse population health impacts in the long-term, but the evidence is limited. Future cohort studies could address the question of the consequences of catch-up growth following LBW more convincingly, with a view to informing future prevention of obesity and NCDs

Living with HIV, disclosure patterns and partnerships a decade after the introduction of HIV programmes in rural South Africa

Prevention of mother-to-child Transmission and HIV Treatment programmes were scaled-up in resource-constrained settings over a decade ago, but there is still much to be understood about women's experiences of living with HIV and their HIV disclosure patterns. This qualitative study explored women's experiences of living with HIV, 6–10 years after being diagnosed during pregnancy. The area has high HIV prevalence, and an established HIV treatment programme. Participants were enrolled in a larger intervention, “Amagugu”, that supported women (n = 281) to disclose their HIV status to their children. Post-intervention we conducted individual in-depth interviews with 20 randomly selected women, stratified by clinic catchment area, from the total sample. Interviews were entered into ATLAS.ti computer software for coding. Most women were living with their current sexual partner and half were still in a relationship with the child's biological father. Household exposure to HIV was high with the majority of women knowing at least one other HIV-infected adult in their household. Eighteen women had disclosed their HIV status to another person; nine had disclosed to their current partner first. Two main themes were identified in the analyses: living with HIV and the normalisation of HIV treatment at a family level; and the complexity of love relationships, in particular in long-term partnerships. A decade on, most women were living positively with HIV, accessing care, and reported experiencing little stigma. However, as HIV became normalised new challenges arose including concerns about access to quality care, and the need for family-centred care. Women's sexual choices and relationships were intertwined with feelings of love, loyalty and trust and the important supportive role played by partners and families was acknowledged, however, some aspects of living with HIV presented challenges including continuing to practise safe sex several years after HIV diagnosis

Maternal HIV infection associated with small-for-gestational age infants but not preterm births: evidence from rural South Africa

BACKGROUND: Human immunodeficiency virus (HIV) is prevalent in many countries where small-for-gestational age (SGA) and premature delivery are also common. However, the associations between maternal HIV, preterm delivery and SGA infants remain unclear. We estimate the prevalence of SGA and preterm (<37 weeks) births, their associations with antenatal maternal HIV infection and their contribution to infant mortality, in a high HIV prevalent, rural area in South Africa.METHODS: Data were collected, in a non-randomized intervention cohort study, on all women attending antenatal clinics (2001-2004), before the availability of antiretroviral treatment. Newborns were weighed and gestational age was determined (based on last menstrual period plus midwife assessment antenatally). Poisson regression with robust variance assessed risk factors for preterm and SGA birth, while Cox regression assessed infant mortality and associated factors.RESULTS: Of 2368 live born singletons, 16.6% were SGA and 21.4% were preterm. HIV-infected women (n= 1189) more commonly had SGA infants than uninfected women (18.1 versus 15.1%; P = 0.051), but percentages preterm were similar (21.8 versus 20.9%; P = 0.621). After adjustment for water source, delivery place, parity and maternal height, the SGA risk in HIV-infected women was higher [adjusted relative risk (aRR) 1.28, 95% confidence interval (CI): 1.06-1.53], but the association between maternal HIV infection and preterm delivery remained weak and not significant (aRR: 1.07, 95% CI: 0.91-1.26). In multivariable analyses, mortality under 1 year of age was significantly higher in SGA and severely SGA than in appropriate-for-gestational-age infants [adjusted hazard ratio (aHR): 2.12, 95% CI: 1.18-3.81 and 2.77, 95% CI: 1.56-4.91], but no difference in infant mortality was observed between the preterm and term infants (aHR: 1.18 95% CI: 0.79-1.79 for 34-36 weeks and 1.31, 95% CI: 0.58-2.94 for <34 weeks).CONCLUSIONS: Maternal HIV infection increases the risk of SGA, but not preterm births, in this cohort

Breastfeeding, HIV exposure, childhood obesity, and prehypertension: a South African cohort study

Background: Evidence on the association between breastfeeding and later childhood obesity and blood pressure (BP) is inconsistent, especially in HIV-prevalent areas where, until recently, HIV-infected women were discouraged from breastfeeding, but obesity is increasingly prevalent. Methods and findings: The Siyakhula cohort (2012–2014), a population-based prospective cohort study, collected data over 3 visits on HIV-negative children ages 7 to 11 years in rural South Africa. We used weight (body mass index [BMI]), fat, and BP as outcome variables and incorporated early life (including mother’s age at delivery and HIV status) and current life factors (including maternal education and current BMI). Our primary exposure was breastfeeding duration. We dichotomized 3 outcome measures using pre-established thresholds for clinical interpretability: (1) overfat: ≥85th percentile of body fat; (2) overweight: >1 SD BMI z score; and (3) prehypertension: ≥90th percentile for systolic BP (SBP) or diastolic BP (DBP). We modelled each outcome using multivariable logistic regression, including stopping breastfeeding, then early life, and finally current life factors. Of 1,536 children (mean age = 9.3 years; 872 girls; 664 boys), 7% were overfat, 13.2% overweight, and 9.1% prehypertensive. Over half (60%) of the mothers reported continued breastfeeding for 12+ months. In multivariable analyses, continued breastfeeding between 6 and 11 months was associated with approximately halved odds of both being overfat (adjusted odds ratio [aOR] = 0.43, 95% confidence interval [CI] 0.21–0.91, P = 0.027) and overweight (aOR = 0.46, CI 0.26–0.82, P = 0.0083), but the association with prehypertension did not reach statistical significance (aOR = 0.72, CI 0.38–1.37, P = 0.32). Children with a mother who was currently obese were 5 times more likely (aOR = 5.02, CI 2.47–10.20, P < 0.001) to be overfat and over 4 times more likely to be overweight (aOR = 4.33, CI 2.65–7.09, P < 0.001) than children with normal weight mothers. Differences between HIV-exposed and unexposed children on any of the outcomes were minimal and not significant. The main study limitation was that duration of breastfeeding was based on maternal recall. Conclusions: To our knowledge, this is the first study examining and quantifying the association between breastfeeding and childhood obesity in an African setting with high HIV prevalence. We observed that breastfeeding was independently associated with reduced childhood obesity for both HIV-exposed and unexposed children, suggesting that promoting optimal nutrition throughout the life course, starting with continued breastfeeding, may be critical to tackling the growing obesity epidemic. In the era of widespread effective antiretroviral treatment for HIV-infected women for life, these data further support the recommendation of breastfeeding for all women

Drug resistance in children at virological failure in a rural KwaZulu-Natal, South Africa, cohort.

BACKGROUND: Better understanding of drug resistance patterns in HIV-infected children on antiretroviral therapy (ART) is required to inform public health policies in high prevalence settings. The aim of this study was to characterise the acquired drug resistance in HIV-infected children failing first-line ART in a decentralised rural HIV programme. METHODS: Plasma samples were collected from 101 paediatric patients (≤15 yrs of age) identified as failing ART. RNA was extracted from the plasma, reverse transcribed and a 1.3 kb region of the pol gene was amplified and sequenced using Sanger sequencing protocols. Sequences were edited in Geneious and drug resistance mutations were identified using the RegaDB and the Stanford resistance algorithms. The prevalence and frequency of mutations were analysed together with selected clinical and demographic data in STATA v11. RESULTS: A total of 101 children were enrolled and 89 (88%) were successfully genotyped; 73 on a non-nucleoside reverse-transcriptase inhibitor (NNRTI)-based regimen and 16 on a protease inhibitor (PI)-based regimen at the time of genotyping. The majority of patients on an NNRTI regimen (80%) had both nucleoside reverse-transcriptase inhibitor (NRTI) and NNRTI resistance mutations. M184V and K103N were the most common mutations amongst children on NNRTI-based and M184V among children on PI-based regimens. 30.1% had one or more thymidine analogue mutation (TAM) and 6% had ≥3 TAMs. Only one child on a PI-based regimen harboured a major PI resistance mutation. CONCLUSIONS: Whilst the patterns of resistance were largely predictable, the few complex resistance patterns seen with NNRTI-based regimens and the absence of major PI mutations in children failing PI-based regimens suggest the need for wider access to genotypic resistance testing in this setting

Need for timely paediatric HIV treatment within primary health care in rural South Africa

<p>Background: In areas where adult HIV prevalence has reached hyperendemic levels, many infants remain at risk of acquiring HIV infection. Timely access to care and treatment for HIV-infected infants and young children remains an important challenge. We explore the extent to which public sector roll-out has met the estimated need for paediatric treatment in a rural South African setting.</p> <p>Methods: Local facility and population-based data were used to compare the number of HIV infected children accessing HAART before 2008, with estimates of those in need of treatment from a deterministic modeling approach. The impact of programmatic improvements on estimated numbers of children in need of treatment was assessed in sensitivity analyses.</p> <p>Findings: In the primary health care programme of HIV treatment 346 children <16 years of age initiated HAART by 2008; 245(70.8%) were aged 10 years or younger, and only 2(<1%) under one year of age. Deterministic modeling predicted 2,561 HIV infected children aged 10 or younger to be alive within the area, of whom at least 521(20.3%) would have required immediate treatment. Were extended PMTCT uptake to reach 100% coverage, the annual number of infected infants could be reduced by 49.2%.</p> <p>Conclusion: Despite progress in delivering decentralized HIV services to a rural sub-district in South Africa, substantial unmet need for treatment remains. In a local setting, very few children were initiated on treatment under 1 year of age and steps have now been taken to successfully improve early diagnosis and referral of infected infants.</p&gt
