Children caught in the long shadow of COVID-19

Despite the more transmissible delta variant being associated with higher rates of COVID-19 in unvaccinated adolescents, children have remained relatively spared from severe disease. Nevertheless, children are indirectly affected by the COVID-19 pandemic, which threatens to have far-reaching consequences. The effect of disruptions of seasonal patterns of circulation of respiratory pathogens on future immunity against such pathogens, childhood immunisation programmes, and HIV and tuberculosis treatment programmes poses a threat to the future wellbeing of children. Furthermore, the economic devastation caused by the pandemic, including an increase in unemployment, gives rise to numerous challenges, such as food insecurity, which is likely to worsen childhood nutritional status. Also, COVID-19 has ongoing effects on the mental wellbeing of children, driven in part by the interruption of schooling and other opportunities to socialise. An increase in psychological illnesses has manifested in children consequent to the stresses of the pandemic, lockdowns, caregiver deaths. In this article, we highlight the indirect effects of COVID-19 on children, and suggest solutions to mitigate against the long-term sequelae. A focused health, nutrition, education and child protection response is required from government and healthcare practitioners to safeguard the health and wellbeing of South African children.

Indian Academy of Pediatrics Revised (2021) Guidelines on Prevention and Treatment of Vitamin D Deficiency and Rickets

The emerging literature on prevalence of vitamin D deficiency in India, prevention and treatment strategies of rickets, and extra-skeletal benefits of vitamin D suggest the need for revising the existing guidelines for prevention and treatment of vitamin D deficiency in India. To review the emerging literature on vitamin D prevalence and need for universal vitamin D supplementation. To suggest optimum vitamin D therapy for treatment of asymptomatic and symptomatic vitamin D deficiency, and rickets. To evaluate the extra-skeletal health benefits of vitamin D in children. A National consultative committee was formed that comprised of clinicians, epidemiologists, endocrinologists, and nutritionists. The Committee conducted deliberations on different aspects of vitamin D deficiency and rickets through ten online meetings between March and September, 2021. A draft guideline was formulated, which was reviewed and approved by all Committee members. The group reiterates the serum 25-hydroxy vitamin D cutoffs proposed for vitamin D deficiency, insufficiency, and sufficiency as <12 ng/mL, 12-20 ng/mL and >20 ng/mL, respectively. Vitamin D toxicity is defined as serum 25OHD >100 ng/mL with hypercalcemia and/or hypercalciuria. Vitamin D supplementation in doses of 400 IU/day is recommended during infancy; however, the estimated average requirement in older children and adolescents (400-600 IU/day, respectively) should be met from diet and natural sources like sunlight. Rickets and vitamin D deficiency should be treated with oral cholecalciferol, preferably in a daily dosing schedule (2000 IU below 1 year of age and 3000 IU in older children) for 12 weeks. If compliance to daily dosing cannot be ensured, intermittent regimens may be prescribed for children above 6 months of age. Universal vitamin D supplementation is not recommended in childhood pneumonia, diarrhea, tuberculosis, HIV and non-infectious conditions like asthma, atopic dermatitis, and developmental disorders. Serum 25-hydroxy vitamin D level of >20 ng/mL should be maintained in children with conditions at high-risk for vitamin deficiency, like nephrotic syndrome, chronic liver disease, chronic renal failure, and intake of anticonvulsants or glucocorticoids.

The impact of the caregiver mobility on child HIV care in the Manhiça District, Southern Mozambique: A clinical based study.

Manhiça District, in Southern Mozambique harbors high HIV prevalence and a long history of migration. To optimize HIV care, we sought to assess how caregiver's mobility impacts children living with HIV (CLHIV)´s continuation in HIV care and to explore the strategies used by caregivers to maintain their CLHIV on antiretroviral treatment (ART). A clinic-based cross-sectional survey conducted at the Manhiça District Hospital between December-2017 and February-2018. We enrolled CLHIV with a self-identified migrant caregiver (moved outside of Manhiça District ≤12 months prior to survey) and non-migrant caregiver, matched by the child age and sex. Survey data were linked to CLHIV clinical records from the HIV care and treatment program. Among the 975 CLHIV screened, 285 (29.2%) were excluded due to absence of an adult at the appointment. A total of 232 CLHIV-caregiver pairs were included. Of the 41 (35%) CLHIV migrating with their caregivers, 38 (92.6%) had access to ART at the destination because either the caregivers travelled with it 24 (63%) or it was sent by a family member 14 (36%). Among the 76 (65%) CLHIV who did not migrate with their caregivers, for the purpose of pharmacy visits, 39% were cared by their grandfather/grandmother, 28% by an aunt/uncle and 16% by an adult brother/sister. CLHIV of migrant caregivers had a non-statistically significant increase in the number of previous reported sickness episodes (OR = 1.38, 95%CI: 0.79-2.42; p = 0.257), ART interruptions (OR = 1.73; 95%CI: 0.82-3.63; p = 0.142) and lost-to-follow-up episodes (OR = 1.53; 95%CI: 0.80-2.94; p = 0.193). Nearly one third of the children attend their HIV care appointments unaccompanied by an adult. The caregiver mobility was not found to significantly affect child's retention on ART. Migrant caregivers adopted strategies such as the transportation of ART to the mobility destination to avoid impact of mobility on the child's HIV care. However this may have implications on ART stability and effectiveness that should be investigated in rural areas.

Childhood trauma and genetic variation in the DAT 40-bp VNTR contribute to HIV-associated neurocognitive disorders.

HIV/AIDS is a major public health burden in South Africa, currently affecting an estimated 13.5% of the population. Despite improved access to antiretroviral therapies, HIV-associated neurocognitive disorders (HAND), characterised by a spectrum of neurocognitive impairment, emotional disturbances and motor abnormalities, continue to persist. Gene-environment interactions contribute to HAND pathophysiology and previous research has identified childhood trauma as an environmental risk factor. Dopaminergic signalling in the prefrontal cortex plays a key role in cognitive function. Thus, variants in genes encoding the dopamine transporter (DAT) and catechol-O-methyltransferase (COMT), which are responsible for dopamine transport and metabolism, could represent genetic risk factors for HAND. This study investigated whether the DAT variable number of tandem repeats (VNTR) and COMT Val158Met (rs4680) polymorphisms are associated with longitudinal change in cognitive function in the context of childhood trauma and HIV. Participants (n = 49 HIV-negative and n = 64 HIV-positive women) completed the Childhood Trauma Questionnaire – Short Form (CTQ-SF) and provided blood for genetic analyses. Global cognitive scores were generated from baseline and one-year follow-up assessments. Following polymerase chain reaction, genotypes were determined using gel electrophoresis and confirmed by Sanger sequencing. Baseline global cognitive scores, genotype, HIV status and CTQ-SF scores were regressed on one-year global cognitive scores in regression models. Analysis of variance was used to examine the effect of including predictor variable interactions on model fit. HIV seropositivity was associated with poorer cognitive performance at one-year follow-up (p = 2.46 ×10−4). The combination of HIV and DAT 10-repeat homozygosity (DAT 10/10) was associated with reduced global cognitive scores in longitudinal models (p = 0.010). Including the interaction between DAT 10/10, childhood trauma, and HIV explained significantly more of the variance in longitudinal cognitive scores (p = 0.008). There were no significant associations with the COMT genotype. Our research indicates that childhood trauma and genetic variation in DAT contribute toward the aetiology of HAND. Future studies in larger cohorts are warranted to verify these results.

Dental caries and its association with the oral microbiomes and HIV in young children\u2014Nigeria (DOMHaIN): a cohort study

BackgroundThis study seeks to understand better the mechanisms underlying the increased risk of caries in HIV-infected school-aged Nigerian children by examining the relationship between the plaque microbiome and perinatal HIV infection and exposure. We also seek to investigate how perinatal HIV infection and exposure impact tooth-specific microbiomes' role on caries disease progression.MethodsThe participants in this study were children aged 4 to 11 years recruited from the University of Benin Teaching Hospital (UBTH), Nigeria, between May to November 2019. Overall, 568 children were enrolled in three groups: 189 HIV-infected (HI), 189 HIV-exposed but uninfected (HEU) and 190 HIV-unexposed and uninfected (HUU) as controls at visit 1 with a 2.99% and 4.90% attrition rate at visit 2 and visit 3 respectively. Data were obtained with standardized questionnaires. Blood samples were collected for HIV, HBV and HCV screening; CD4, CD8 and full blood count analysis; and plasma samples stored for future investigations; oral samples including saliva, buccal swabs, oropharyngeal swab, tongue swab, dental plaque were collected aseptically from participants at different study visits.ConclusionsResults from the study will provide critical information on how HIV exposure, infection, and treatment, influence the oral microbiome and caries susceptibility in children. By determining the effect on community taxonomic structure and gene expression of dental microbiomes, we will elucidate mechanisms that potentially create a predisposition for developing dental caries. As future plans, the relationship between respiratory tract infections, immune and inflammatory markers with dental caries in perinatal HIV infection and exposure will be investigated.

Mother-to-Child Transmission of HIV and Associated Factors Among Exposed Infants in Pastoralist Health Facilities, South Omo Zone, Ethiopia, 2020 - A Retrospective Cross-Sectional Study.

BackgroundAlthough HIV/AIDS is affecting all age groups, it is a primary cause of illness and deaths among children globally. A significant bulk of HIV infections in children under the age of 15 were as a result of vertical transmission, where it accounts for 95% of childhood HIV infections in Ethiopia.ObjectiveTo assess the proportion of mother-to-child transmission (MTCT) of HIV and associated factors among exposed infants on follow-up in pastoralist health facilities, South Omo, Ethiopia.MethodologyA retrospective, cross-sectional study was employed among 228 HIV-exposed infants. Medical records of HIV-exposed infant-mother pairs in the study institutions were extracted. The confirmatory HIV serostatus of every infant was taken at the end of 24 months. Data were entered in Epi Data 4.2 version and exported to SPSS version 25 for final analysis. Multivariable logistic regression analysis was used to identify significant predictor variables at P-value < 0.05.ResultsA total of 228 records were included in the analysis. The rate of HIV transmission was 5.3% (95% CI: 2.6–8.3%). Not receiving antiretroviral prophylaxis at birth (AOR = 5.8, 95% CI: 1.02–33.53), absence of maternal antiretroviral prior to current pregnancy (AOR = 5.6, 95% CI: 1.14–28.1), and mother’s advanced World Health Organization clinical stage of HIV (AOR: 10.5, 95% CI: 1.4–81) were associated with MTCT of HIV.ConclusionThis study identified a high proportion of MTCT among exposed infants in the study area. Not receiving antiretrovirals prior to pregnancy and advanced WHO clinical stage of HIV, and not getting antiretroviral prophylaxis at birth resulted in higher risk of MTCT of HIV. Hence, health workers and policy-makers should offer antiretroviral prophylaxis, put mothers on antiretroviral therapy and limit the stage of HIV at lower WHO clinical stages.

An HLA-I signature favouring KIR-educated Natural Killer cells mediates immune control of HIV in children and contrasts with the HLA-B-restricted CD8+ T-cell-mediated immune control in adults.

Natural Killer (NK) cells contribute to HIV control in adults, but HLA-B-mediated T-cell activity has a more substantial impact on disease outcome. However, the HLA-B molecules influencing immune control in adults have less impact on paediatric infection. To investigate the contribution NK cells make to immune control, we studied >300 children living with HIV followed over two decades in South Africa. In children, HLA-B alleles associated with adult protection or disease-susceptibility did not have significant effects, whereas Bw4 (p = 0.003) and low HLA-A expression (p = 0.002) alleles were strongly associated with immunological and viral control. In a comparator adult cohort, Bw4 and HLA-A expression contributions to HIV disease outcome were dwarfed by those of protective and disease-susceptible HLA-B molecules. We next investigated the immunophenotype and effector functions of NK cells in a subset of these children using flow cytometry. Slow progression and better plasma viraemic control were also associated with high frequencies of less terminally differentiated NKG2A+NKp46+CD56dim NK cells strongly responsive to cytokine stimulation and linked with the immunogenetic signature identified. Future studies are indicated to determine whether this signature associated with immune control in early life directly facilitates functional cure in children.

Impact of adverse childhood experiences on women’s psychosocial and HIV-related outcomes and early child development in their offspring

ABSTRACT Adverse childhood experiences (ACEs) may have a critical influence on adult outcomes and subsequent offspring development, but few data have explored the effects of ACEs in low-resource settings where the burdens of childhood adversity and HIV are high. Among mothers living with HIV in Cape Town, we examined the effects of ACEs on maternal psychosocial and HIV-related outcomes, as well as early child development in their offspring aged 36–60 months. The World Health Organization’s Adverse Childhood Experiences International Questionnaire was used to measure maternal reports of ACEs, and the Ages & Stages Questionnaire to screen for developmental delays in their offspring. Among 353 women (median age: 32 years), 84% reported ≥1 ACEs. Increased report of ACEs was strongly associated with depressive symptoms, hazardous alcohol use, intimate partner violence and self-reported suboptimal adherence to antiretroviral therapy. These associations were driven by more severe childhood experiences, including abuse, neglect and exposure to collective violence. Among 255 women who reported on their child’s development, maternal ACEs were associated with poorer socioemotional development. These data suggest that childhood adversity has long-term effects on maternal outcomes as well as their children’s socioemotional development and point to ACEs that might be targeted for screening and intervention.

The Etiology of Pneumonia in HIV-infected Zambian Children: Findings From the Pneumonia Etiology Research for Child Health (PERCH) Study.

Despite recent declines in new pediatric HIV infections and childhood HIV-related deaths, pneumonia remains the leading cause of death in HIV-infected children under 5. We describe the patient population, etiology and outcomes of childhood pneumonia in Zambian HIV-infected children. As one of the 9 sites for the Pneumonia Etiology Research for Child Health study, we enrolled children 1-59 months of age presenting to University Teaching Hospital in Lusaka, Zambia, with World Health Organization-defined severe and very severe pneumonia. Controls frequency-matched on age group and HIV infection status were enrolled from the Lusaka Pediatric HIV Clinics as well as from the surrounding communities. Clinical assessments, chest radiographs (CXR; cases) and microbiologic samples (nasopharyngeal/oropharyngeal swabs, blood, urine, induced sputum) were obtained under highly standardized procedures. Etiology was estimated using Bayesian methods and accounted for imperfect sensitivity and specificity of measurements. Of the 617 cases and 686 controls enrolled in Zambia over a 24-month period, 103 cases (16.7%) and 85 controls (12.4%) were HIV infected and included in this analysis. Among the HIV-infected cases, 75% were <1 year of age, 35% received prophylactic trimethoprim-sulfamethoxazole, 13.6% received antiretroviral therapy and 36.9% of caregivers reported knowing their children's HIV status at time of enrollment. A total of 35% of cases had very severe pneumonia and 56.3% had infiltrates on CXR. Bacterial pathogens [50.6%, credible interval (CrI): 32.8-67.2], Pneumocystis jirovecii (24.9%, CrI: 15.5-36.2) and Mycobacterium tuberculosis (4.5%, CrI: 1.7-12.1) accounted for over 75% of the etiologic fraction among CXR-positive cases. Streptococcus pneumoniae (19.8%, CrI: 8.6-36.2) was the most common bacterial pathogen, followed by Staphylococcus aureus (12.7%, CrI: 0.0-25.9). Outcomes were poor, with 41 cases (39.8%) dying in hospital. HIV-infected children in Zambia with severe and very severe pneumonia have poor outcomes, with continued limited access to care, and the predominant etiologies are bacterial pathogens, P. jirovecii and M. tuberculosis.

Population-based socio-demographic household assessment of livelihoods and health among communities in Migori County, Kenya over multiple timepoints (2021, 2024, 2027): A study protocol.

Migori County is located in western Kenya bordering Lake Victoria and has traditionally performed poorly on important health metrics, including child mortality and HIV prevalence. The Lwala Community Alliance is a non-governmental organization that serves to promote the health and well-being of communities in Migori County through an innovative model utilizing community health workers, community committees, and high-quality facility-based care. This has led to improved outcomes in areas served, including improvements in childhood mortality. As the Lwala Community Alliance expands to new programming areas, it has partnered with multiple academic institutions to rigorously evaluate outcomes. We describe a repeated cross-sectional survey study to evaluate key health metrics in both areas served by the Lwala Community Alliance and comparison areas. This will allow for longitudinal evaluation of changes in metrics over time. Surveys will be administered by trained enumerators on a tablet-based platform to maintain high data quality.

Abacavir pharmacokinetics in African children living with HIV: A pooled analysis describing the effects of age, malnutrition and common concomitant medications.

AimsAbacavir is part of WHO‐recommended regimens to treat HIV in children under 15 years of age. In a pooled analysis across four studies, we describe abacavir population pharmacokinetics to investigate the influence of age, concomitant medications, malnutrition and formulation.MethodsA total of 230 HIV‐infected African children were included, with median (range) age of 2.1 (0.1–12.8) years and weight of 9.8 (2.5–30.0) kg. The population pharmacokinetics of abacavir was described using nonlinear mixed‐effects modelling.ResultsAbacavir pharmacokinetics was best described by a two‐compartment model with first‐order elimination, and absorption described by transit compartments. Clearance was predicted around 54% of its mature value at birth and 90% at 10 months. The estimated typical clearance at steady state was 10.7 L/h in a child weighing 9.8 kg co‐treated with lopinavir/ritonavir, and was 12% higher in children receiving efavirenz. During coadministration of rifampicin‐based antituberculosis treatment and super‐boosted lopinavir in a 1:1 ratio with ritonavir, abacavir exposure decreased by 29.4%. Malnourished children living with HIV had higher abacavir exposure initially, but this effect waned with nutritional rehabilitation. An additional 18.4% reduction in clearance after the first abacavir dose was described, suggesting induction of clearance with time on lopinavir/ritonavir‐based therapy. Finally, absorption of the fixed dose combination tablet was 24% slower than the abacavir liquid formulation.ConclusionIn this pooled analysis we found that children on lopinavir/ritonavir or efavirenz had similar abacavir exposures, while concomitant TB treatment and super‐boosted lopinavir gave significantly reduced abacavir concentrations.

Improving Sampling Efficiency for Determining Pediatric HIV Prevalence in National Surveys: Evidence From 8 Sub-Saharan African Countries.

Measurement of mother-to-child HIV transmission through population-based surveys requires large sample sizes because of low HIV prevalence among children. We estimate potential improvements in sampling efficiency resulting from a targeted sample design. Eight countries in sub-Saharan Africa with completed Population-based HIV Impact Assessment (PHIA) surveys as of 2017. The PHIA surveys used a geographically stratified 2-stage sample design with households sampled from randomly selected census enumeration areas. Children (0-14 years of age) were eligible for HIV testing within a random subsample of households (usually 50%). Estimates of child HIV prevalence in each country were calculated using jackknife replicate weights. We compared sample sizes and precision achieved using this design with a 2-phase disproportionate sample design applied to strata defined by maternal HIV status and mortality. HIV prevalence among children ranged from 0.4% (95% confidence interval: 0.2 to 0.6) in Tanzania to 2.8% (95% confidence interval: 2.2 to 3.4) in Eswatini with achieved relative standard errors between 11% and 21%. The expected precision improved in the targeted design in all countries included in the analysis, with proportionate reductions in mean squared error ranging from 27% in Eswatini to 61% in Tanzania, assuming an equal sample size. Population-based surveys of adult HIV prevalence that also measure child HIV prevalence should consider targeted sampling of children to reduce required sample size, increase precision, and increase the number of positive children tested. The findings from the PHIA surveys can be used as baseline data for informing future sample designs.

Fixed-dose combination bictegravir, emtricitabine, and tenofovir alafenamide in adolescents and children with HIV: week 48 results of a single-arm, open-label, multicentre, phase 2/3 trial

Bictegravir is a potent integrase strand-transfer inhibitor (INSTI) with a high genetic barrier to resistance. Bictegravir, coformulated with emtricitabine and tenofovir alafenamide, is recommended by key European and US HIV treatment guidelines as the preferred single-tablet regimen for adults and adolescents. The aim of this study was to assess the pharmacokinetics, safety, and efficacy of switching to this regimen in virologically suppressed children and adolescents with HIV. In this single-arm, open-label trial, we enrolled virologically suppressed children and adolescents (aged 6 to <18 years) with HIV at 22 hospital clinics in South Africa, Thailand, Uganda, and the USA. Eligible participants had a bodyweight of at least 25 kg, were virologically suppressed (HIV-1 RNA <50 copies per mL) on a stable ART regimen for at least 6 months before screening, had a CD4 count of at least 200 cells per μL, and an estimated glomerular filtration rate of at least 90 mL/min per 1·73 m2 by the Schwartz formula at screening. All participants received the fixed-dose regimen of coformulated bictegravir 50 mg, emtricitabine 200 mg, and tenofovir alafenamide 25 mg once daily. Pharmacokinetic analysis was used for dosing confirmation, and results compared with adult values. The primary outcomes were area under the curve at the end of the dosing interval (AUCtau) and concentration at the end of the dosing interval (Ctau) of bictegravir, and incidence of treatment-emergent adverse events and laboratory abnormalities at week 24. Efficacy and safety analyses included all participants who received at least one dose of study drug. We report the 48-week results. This study is registered with ClinicalTrials.gov, NCT02881320. Between Sept 29, 2016 and Feb 16, 2018, we enrolled 102 participants. 100 participants received bictegravir, emtricitabine, and tenofovir alafenamide (cohort 1 [adolescents aged 12 to <18 years], n=50; cohort 2 [children aged 6 to <12 years], n=50). The mean bictegravir AUCtau was 89 100 ng × h/mL (coefficient of variation 31·0%) in adolescents (cohort 1) and 128 000 ng × h/mL (27·8%) in children (cohort 2). Compared with adults, bictegravir Ctau was 35% lower in adolescents and 11% lower in children. The 90% CIs of both parameters were within the predefined pharmacokinetic equivalence boundary and within overall range of exposures observed in adults and deemed to be safe and efficacious (geometric least-squares mean ratio [GLSM] 86·3% [90% CI 80·0-93·0] for AUCtau and 65·4% [58·3-73·3] for Ctau in adolescents; GLSM 125% [90% CI 117-134] for AUCtau and 88·9% [80·6-98·0] for Ctau for children). Bictegravir, emtricitabine, and tenofovir alafenamide was well tolerated; most adverse events were grade 2 or less in severity and no study drug-related serious adverse events were reported. One participant discontinued study drug due to adverse events (grade 2 insomnia and anxiety). Virological suppression (HIV-1 RNA <50 copies per mL) was maintained by all 100 participants at week 24 and by 98 (98%) of 100 at week 48; no participants had treatment-emergent resistance. In adolescents and children with HIV, the bictegravir, emtricitabine, and tenofovir alafenamide single-tablet regimen was well tolerated and maintained virological suppression. Our data support the treatment of HIV in adolescents and children with this single-tablet regimen. At present, the single-tablet regimen is recommended as first-line treatment in the USA for adolescents and as an alternative regimen in children and has the potential to represent an important regimen in the paediatric population.

Fathers and grandmothers experiences participating in nutrition peer dialogue groups in Vihiga County, Kenya.

Grandmothers and fathers are key influencers of maternal and child nutrition and are increasingly included in interventions. Yet, there is limited research exploring their experiences participating in interventions. This study reports on findings from a qualitative process evaluation of a quasi‐experimental study that we conducted with grandmother and father peer dialogue groups to support maternal, infant and young child feeding practices in western Kenya. The aim was to explore grandmother and father experiences participating in interventions and how participation influences care and feeding practices. Grandmother and father peer educators received training to facilitate discussions about maternal and child nutrition, HIV and infant feeding, family communication, and family members' roles. Father peer educators also received training on gender inequities and power dynamics. In the original quasi‐experimental study, the intervention was associated with increased social support and improvements in some complementary feeding practices. The process evaluation explored participants' experiences and how participation influenced infant care and feeding practices. We used Atlas.ti to thematically analyse data from 18 focus group discussions. The focus group discussions revealed that grandmothers and fathers valued their groups, the topics discussed and what they learned. Grandmothers reported improved infant feeding and hygiene practices, and fathers reported increased involvement in child care and feeding and helping with household tasks. Both described improved relationships with daughters‐in‐law or wives. This study highlights the importance of engaging influential family members to support child nutrition and identifies factors to build cohesion among group members, by building on grandmothers' roles as advisors and expanding fathers' roles in nutrition through gender transformative activities.

South African Fathers Involvement and Their Adolescents' Sexual Risk Behavior and Alcohol Consumption.

Although considerable research has examined the influence of parent-adolescent relationships on the sexual health of adolescents, there is a great need for research to understand the influence of fathers on their children's HIV sexual risk behavior, particularly in sub-Saharan Africa. We examined how the residence and the involvement of fathers are related to their children's HIV sexual risk and alcohol consumption behaviors. A cross-sectional survey was completed by 175 sixth-grade adolescents in the Eastern Cape Province, South Africa. Analyses showed that adolescents living with their fathers had fewer sexual partners (B = -0.606, SE = 0.299, p = .043) and consumed alcohol less frequently (B = -0.642, SE = 0.294, p = .029). Adolescents who spent more quality days with their fathers in the past 30days had fewer sexual partners (B = -0.103, SE = 0.039, p = .008) and had condomless sex less frequently (B = -0.097, SE = 0.047, p = 0.041). It was also found that there were significant father-residence × child-gender interactions on sexual debut (B = 1.132, SE = 0.564, p = .045) and on frequency of condomless sex (B = -2.140, SE = 0.924, p = .021). These interactions indicate that boys living with their fathers were less likely to have had vaginal intercourse than girls and that girls living with their fathers were less likely to have unprotected sex than boys. This study highlights the importance of South African fathers' roles in their adolescent children's HIV sexual risk and alcohol drinking behaviors and the need to promote father-child relationships for adolescent health. The results suggest that health programs aiming to reduce South African adolescents' HIV sexual risk behaviors and alcohol consumption consider strategies that target their fathers.

Participatory Methods for Stigma Reduction with HIV-Affected Families

HIV stigma contributes to risks for poor health; these risks are exacerbated by additional stigmas of race, gender, sexual orientation, and substance abuse history. As women continue to be infected by HIV and as people with HIV are living longer, their children, most of whom are not HIV infected, are affected by their parent’s HIV status. Children may feel stigma as acutely as their HIV-positive (HIV+) parents, contributing to the children’s vulnerability. Children of HIV+ mothers have more emotional problems, disrupted relationships, and poor school outcomes than those whose mothers are not living with HIV. As we learn about stigma’s impact beyond the individual, we are compelled to respond systemically within families to reduce future generations’ vulnerability to HIV and other risks. Based on a line of inquiry with HIV-affected teens about their stigma experiences, our multidisciplinary team discovered stigma’s impact on our ability, not only to study stigma, but to engage parents and especially their children in services and research. We draw on these findings and the literature on community-based participation to contend that participatory methods have value, not only for research and program development, but in reducing the impact of stigma with our HIV-affected partners. The participatory process is as important to stigma reduction as knowledge and service development outcomes. Participatory methods can expand our potential for breaking the cycle of intergenerational vulnerability by strengthening family skills and capacity and enhancing self-worth so those affected by HIV are empowered to overcome stigma’s impact.

Caregiver and child factors predicting HIV status disclosure among children enrolled on ART: a cross-regional study in Addis Ababa and Oromia, Ethiopia

ABSTRACT Introduction: The World Health Organization recommends that for children of school age who are HIV-positive, their HIV status should be disclosed. The purpose of this study was to get a better understanding of disclosure rates among school-aged children in Ethiopia and to investigate the variables amongst caregivers and children predicting disclosure/non-disclosure. Methods: Data from 231 children were collected prospectively through a structured questionnaire after initiation of ART treatment. Data were analysed with χ 2 test for comparison and logistic regression to verify the prediction of independent variables with the child’s HIV status disclosure. Results: Child age, caregiver marital status and caregiver residence were significantly associated with disclosure at 6 months. Similarly, child age, caregiver marital status and caregiver–child relationship were found to be significantly associated with disclosure at 12 months. Child age greater than nine years at 6 months (aOR 8.5, 95% CI: 2.5–29) and at 12 months (aOR 5.3, 95% CI: 1.8–16) were found to be significantly associated with disclosure. Furthermore, at 6 months, children with caregivers who had a partner they were not married to were more likely to disclose the HIV status to the child. This study suggests that paediatrics HIV care and treatment should consider these issues through contextualized strategies on child HIV disclosure and related challenges. Large-scale studies are required to better generalize on the subject.
