Maternal Factors Associated With Infant Neurodevelopment in HIV-Exposed Uninfected Infants

Background

This study evaluated maternal factors associated with infant neurodevelopmental outcomes among HIV-exposed uninfected (HEU) infants in rural South Africa. This study followed pregnant women living with HIV pre- and postpartum and evaluated sociodemographic factors, use of antiretrovirals (ARVs), and mental health factors as predictors of HEU infant developmental outcomes (cognitive, receptive, and expressive communication, fine and gross motor skills).

Methods

Participants were 80 mother–infant dyads. Mothers were assessed during pregnancy, and HEU infant development was assessed at a mean (SD) of 13.36 (1.89) months of age.

Results

Women were an average (SD) of 28.9 (5.2) years of age, and infants were on average 13.4 (1.9) months old. An analysis of covariance indicated that infants whose mothers had ARV detected in dry blood spots at 32 weeks of pregnancy had lower functioning scores in the cognitive domain than those with undetected ARV (n = 14; M, 15.3 vs 17.2; P = .048). Antenatal physical intimate partner violence was also associated with delayed cognitive functioning (F (1, 74), 4.96; P = .029).

Conclusions

This study found risks for delayed infant cognitive development to be associated with the use of ARV during pregnancy and intimate partner violence, although findings merit replication due to the low sample size. Given the growing number of HEU infants, the necessity to better understand the potential toxicity of ARV exposure in utero is apparent. Similarly, the need for preventing intimate partner violence and screening for, and managing, developmental delays among these infants is increasing.

Sexual risk behavior among HIV-infected women in South Africa at 12-months postpartum

The postnatal period is a time of increased susceptibility to HIV infection and superinfection for postpartum women, sexual partners, and infants. This study examined the effect of a prevention to mother-to-child transmission of HIV intervention compared to standard care, and factors associated with unprotected last sex and inconsistent condom use at 12-months postpartum. Participants were N = 1399 HIV-infected women 6-30 weeks pregnant (M = 18 weeks (SD = 5.75)) assessed during pregnancy and 12-months postpartum. Women were aged an average of 28 (SD = 5.82); 48% reported 10-11 years of education. Older age (adjusted odds ratio [AOR] = 1.00) and being employed (AOR = 1.51) were associated with greater odds of unprotected sex at 12-month postpartum. Disclosure of HIV status (AOR = 0.64) and greater male involvement during pregnancy (AOR = 0.92) were associated with lower odds of unprotected sex at 12-month postpartum. HIV negative or unknown partner status (AOR = 0.45) and greater depressive symptoms (AOR = 0.97) were associated with lower odds of inconsistent condom use at 12-months postpartum. The intervention was not associated with reduced sexual risk behavior. Future studies should address male involvement and consider measurement of culturally tailored male involvement constructs for men South Africa. Perinatal women may require support for sexual communication and gender equity to reduce sexual risk.

Impact of male partner involvement on mother-to-child transmission of HIV and HIV-free survival among HIV-exposed infants in rural South Africa: Results from a two phase randomised controlled trial

BACKGROUND

The Sub-Saharan Africa region still remains the epicentre of the global HIV/AIDS epidemic. With regards to new paediatric HIV infections, almost 90% of new HIV infections are among children (aged 0-14 years), largely through mother to child transmission. Male Partner Involvement in Prevention of Mother to Child Transmission programmes is now strongly advocated as being key in improving infant outcomes. This study describes the role of Male Partner Involvement on infant HIV infection and mortality survival in the first year among HIV-exposed infants born from HIV positive mothers.

METHODS

This study was a two-phase, two condition (intervention or control) longitudinal study as part of a clinic-randomized Prevention of Mother to Child Transmission controlled trial. For Phase 1, female participants were recruited without their male partners. In Phase 2, both female and male participants were enrolled in the study as couples in order to encourage active Male Partner Involvement during pregnancy. Participants had two assessments prenatally (8-24 weeks and 32 weeks) and three assessments postnatally (6 weeks, 6 months, and 12 months).

RESULTS

About 1424 women were eligible for recruitment into the study and 18 eligible women declined to participate. All women had a partner; 54% were unmarried, 26% were cohabiting, and 20% were married. Just over half (55%) of the women had been diagnosed with HIV during the current pregnancy. Phase 1 had significantly more HIV-infected infants than Phase 2 at 12-months postpartum (aOR = 4.55 [1.38, 15.07]). Increased depressive symptoms were associated with infant HIV infection at 12-months (aOR = 1.06 [1.01, 1.10]). Phase 1 also had a significantly greater proportion of dead and HIV-infected infants than Phase 2 at 12-months (aOR = 1.98 [1.33, 2.94]).

CONCLUSION

Male partner involvement in antenatal care is critical in ensuring infant survival and HIV infection among children born to HIV-positive mothers. This study highlights the high risk of ante-and-post natal depression and underscores the need of screening for depression during pregnancy.

Increasing acceptability and uptake of voluntary male medical circumcision in Zambia: implementing and disseminating an evidence-based intervention

Voluntary medical male circumcision (VMMC) uptake in Africa could prevent 3.4 million HIV infections across a 10 year span. In Zambia, however, ~80 per cent of uncircumcised men report no interest in undergoing VMMC. The Spear & Shield (S&S) intervention has been shown to be more effective than control or observation of only conditions at increasing the number of VMMCs. This study identified predictors of S&S implementation success or failure to create an "early warning" system to enable remedial action during implementation. Participants were n = 48 staff members from 12 community health facilities conducting the S&S program in Lusaka Province, Zambia. Quantitative assessments included demographics, provider attitudes, barriers to research uptake, staff burnout, and organizational readiness. Qualitative interviews were also conducted and quantified for analysis using the Consolidated Framework for Implementation Research (CFIR). Two-thirds (66%) of staff were women with a mean age of 37.67 years (SD = 7.51). Quantitatively, staff performance (p = .033) and decreased levels of staff burnout (p = .025) were associated with S&S implementation success. Qualitatively, constructs such as improved planning, executing, and self-reflection and evaluation were associated with S&S implementation success (p = .005). Identifying these factors facilitated remedial action across health facilities. This study illustrates the utility of the CFIR to guide program decision making in VMMC implementation in the Zambian context. Early identification of challenges to implementation may enable remedial action to enhance the likelihood of program sustainability. Effective monitoring strategies for HIV prevention interventions may thus enhance dissemination, implementation, and sustainability goals to bridge research and practice.

Behavioral Medicine: a retro/prospective view of the field

The year 2017 was the 40th anniversary of the convening of the Yale Conference on Behavioral Medicine (Schwartz and Weiss, 1977). In honor of this defining moment in the history of the birthing of behavioral medicine as a formal integrative field of biobehavioral theories, research and applications, we were invited by the editors to take a retrospective and prospective look at the field. Recognizing that much has been written about this history over the years, we decided to write about the "back-channel," presenting never-before shared events associated with the birthing and evolution of the field in a way that would be fun to write and read. In the process we look back at the evolving definitions of behavioral medicine in light of contemporary advances and controversies in science. Our review includes a discussion of some of the present challenges/opportunities, and then considers the future with some "outside the box" possibilities. We outline some of the enormous advances which have taken place in technology since the 1970s and consider how such technologies can be transformative in redefining our field.

The effect of male involvement and a prevention of mother-to-child transmission (PMTCT) intervention on depressive symptoms in perinatal HIV-infected rural South African women

This study investigated perinatal depressive symptoms among HIV-infected women enrolled in a cluster-randomized, controlled trial in South Africa. Women (n = 1370) attending 12 community health centers were consecutively enrolled in a two-phase (phase 1 = without a male partner, phase 2 = with a male partner) and two-condition (experimental or control) prevention of mother-to-child transmission (PMTCT) intervention. Women were enrolled at 8-24 weeks pregnant and followed postpartum at 6 weeks and 6 and 12 months (retention rate = 69.8%). Antenatally, 45.4% of women were above the 12-point Edinburgh Postnatal Depression Scale (EPDS) cutoff, 30.2% were above the cutoff at 6 weeks, and 34.2% and 36.9% at 6 months and 12 months postpartum, respectively. In multilevel regression analyses, depressive symptoms decreased over time among women in phase 2 participating in the intervention condition, but neither condition nor phase alone was associated with a decrease in depression. Greater HIV stigma, increased psychological intimate partner violence, less male involvement, lower education, and non-adherence during pregnancy were associated with increased depressive symptoms over the perinatal period. Results indicated that women participating had high levels of depressive symptoms (> 40% prenatally and > 30% postnatally), and the combination of the multi-session PMTCT intervention plus male partner participation contributed to a reduction in depressive symptoms. Results suggest that interventions targeting the reduction of depressive symptoms in perinatal HIV-positive women by increasing male involvement and decreasing HIV stigma and intimate partner violence are needed to reduce depression in this vulnerable population.

Adolescent and young adult couples' views of intravaginal practices: a qualitative analysis of a pilot study

Purpose

In this study, we evaluated the risk behaviors that are drivers of the HIV epidemic among adolescent girls and young women in Zambia using a focus group research technique.

Subjects and methods

Eighteen adolescent couples (n=18 females and 18 males) aged 16–24 participated in six focus groups discussions (3 per gender) convened at three health facilities in Lusaka, Zambia. Focus group moderators utilized a set of open-ended questions to guide the 60-minute sessions. The focus group audio recordings were transcribed, coded, and analyzed using qualitative content analysis in Nvivo 11.

Results

Three themes and four subthemes were identified relating to adolescent and young adult couples’ knowledge, views, and male partner attitudes toward intravaginal practices (IVPs). The first theme, knowledge and rationale for IVPs, consisted of the subthemes relating to why adolescents and young adult couples engage in IVPs and assessed their knowledge of health risks associated with IVPs. The second theme, attitudes toward IVPs, consisted of the subtheme willingness to stop or support partner to discontinue IVP and practices toward IVP and strategies for changing. The third theme, strategies for changing IVPs, consisted of the subtheme raise awareness.

Conclusion

IVPs used for cleaning purposes were perceived as essential to enhancing hygiene, health, and sexual satisfaction for both girls and boys. However, couples expressed concern about the health effects of IVPs used for tightening and a desire for learning more about this practice as well as stopping it.

The Use of Efavirenz During Pregnancy is Associated with Suicidal Ideation in Postpartum Women in Rural South Africa

Efavirenz is used for the management of HIV infection during pregnancy in South Africa (SA), but it is contraindicated in patients with history of depression due to possible suicidal ideation. This study compared suicidal ideation 12-months postpartum among women receiving and not receiving efavirenz in rural SA, where high rates of depression have been identified. Antenatal psychological intimate partner violence (IPV; AOR = 1.04), depression (AOR = 1.06) and detection of efavirenz in dried blood spot at 32 weeks predicted suicidal ideation 12-months postnatally (AOR = 2.29), controlling for antenatal stigma and physical IPV. Findings support using alternative agents for the management of HIV during pregnancy.

Pre- and postnatal exposure to intimate partner violence among South African HIV-infected mothers and infant developmental functioning at 12 months of age

In rural South Africa, pregnant HIV-infected women report high rates of psychological (55%) and physical (20%) intimate partner violence (IPV). IPV increases the risk of infant developmental delays. Such delays may have negative socioemotional and cognitive outcomes throughout the lifespan. This paper assesses the relationship between IPV and infant development in rural South Africa. The present investigation was a cross-sectional add-on follow-up designed retrospectively. A randomly selected sub-sample of mothers from the main randomized controlled trial (n = 72) were asked to participate with their infants at 12 months of age; all women invited agreed to participate. Women were 18.35 ± 5.47 weeks pregnant; demographics, HIV disclosure status, and pre- and postnatal IPV measured via the Conflict Tactics Scale during pregnancy at baseline and 12 months post-partum were assessed. Infant HIV serostatus and developmental functioning at 12 months of age were assessed. Women were a mean age of 29 ± 2 years. One third had completed at least 12 years of education and had a monthly income of ~ US$76. At 12 months post-partum, 6% of infants tested HIV seropositive. Postnatal physical IPV was associated with delays in cognitive and receptive language development p < 0.05, but only in unadjusted analyses. This study identified an association between early IPV exposure and infant cognitive and receptive communication delays. Given the small sample size, findings support replication. Longitudinal studies are needed to confirm temporal order and identify appropriate timing for interventions in HIV-exposed infants.

Correlates of Suicidal Ideation During Pregnancy and Postpartum Among Women Living with HIV in Rural South Africa

In developing countries, up to 20% of maternal deaths during pregnancy are due to suicide, and being HIV-infected confers additional risk. This manuscript sought to identify perinatal correlates of suicidal ideation among women living with HIV (WLHIV) in rural South Africa. Pregnant WLHIV (N = 681) were recruited and re-assessed at 12-months postpartum. Mean age was 28.3 (SD = 5.7) years and 68% were below the poverty line. Prenatal suicidal ideation was 39%; suicidal ideation continued for 7% at 12 months, 13% experienced incident suicidal ideation, and for 19% suicidal ideation had stopped postnatally. Intimate partner violence (AOR = 1.17) and depression (AOR = 1.14) predicted sustained suicidal ideation. Increased income (AOR = 2.25) and greater stigma (AOR = 1.33) predicted incident suicidal ideation. Younger age (AOR = 0.94), disclosure of HIV status to partner (AOR = 0.60), and greater stigma (AOR = 1.24) predicted postnatal cessation of suicidal ideation. Perinatal care may provide windows of opportunity for identification and treatment of suicidal ideation.

A Bayesian Analysis of Prenatal Maternal Factors Predicting Nonadherence to Infant HIV Medication in South Africa

While efforts to prevent mother-to-child transmission of HIV been successful in some districts in South Africa, rates remain unacceptably high in others. This study utilized Bayesian logistic regression to examine maternal-level predictors of adherence to infant nevirapine prophylaxis, including intimate partner violence, maternal adherence, HIV serostatus disclosure reaction, recency of HIV diagnosis, and depression. Women (N = 303) were assessed during pregnancy and 6 weeks postpartum. Maternal adherence to antiretroviral therapy during pregnancy predicted an 80% reduction in the odds of infant nonadherence [OR 0.20, 95% posterior credible interval (.11, .38)], and maternal prenatal depression predicted an increase [OR 1.04, 95% PCI (1.01, 1.08)]. Results suggest that in rural South Africa, failure to provide medication to infants may arise from shared risk factors with maternal nonadherence. Intervening to increase maternal adherence and reduce depression may improve adherence to infant prophylaxis and ultimately reduce vertical transmission rates.

The role of social support in the association between childhood trauma and depression among HIV-infected and HIV-uninfected individuals

Childhood trauma (CT) - emotional, physical or sexual abuse, or emotional or physical neglect - has been associated with HIV infection and can lead to poor health outcomes and depression in adulthood. Though the impact of CT on depression may be decreased by social support, this may not be true of individuals living with HIV, due to the additive traumatic effects of both CT and acquisition of HIV. This study examined social support, depression, and CT among HIV-infected (n = 134) and HIV-uninfected (n = 306) men and women. Participants (N = 440) were assessed regarding sociodemographic characteristics, CT, depression, and social support. Participants were racially and ethnically diverse, 36 ± 9 years of age on average, and 44% had an income of less than USD$500 a month. Among HIV-uninfected individuals, social support explained the association between depression in persons with CT ( b = 0.082, bCI [0.044, 0.130]). Among HIV-infected individuals, after accounting for sociodemographic characteristics, social support did not explain the association between depression and CT due to lower levels of social support among HIV-infected individuals [95% CI: -0.006, 0.265]. The quality of social support may differ among HIV-infected persons due to decreased social support and smaller social networks among those living with HIV. Depressive symptoms among those living with HIV appear to be less influenced by social support, likely due to the additive effects of HIV infection combined with CT.

Physician-delivered motivational interviewing to improve adherence and retention in care among challenging HIV-infected patients in Argentina (COPA2): study protocol for a cluster randomized controlled trial

BACKGROUND

"Challenging" HIV-infected patients, those not retained in treatment, represent a critical focus for positive prevention, as linkage to care, early initiation of antiretroviral therapy, adherence and retention in treatment facilitate viral suppression, thus optimizing health and reducing HIV transmission. Argentina was one of the first Latin American countries to guarantee HIV prevention, diagnosis and comprehensive care services, including antiretroviral medication, which removed cost and access as barriers. Yet, dropout occurs at every stage of the HIV continuum. An estimated 110,000 individuals are HIV-infected in Argentina; of these, 70% have been diagnosed and 54% were linked to care. However, only 36% have achieved viral suppression and 31% of those diagnosed delayed entry to care. To achieve meaningful reductions in HIV infection at the community level, innovative strategies must be developed to re-engage patients. Motivational Interviewing (MI) is a patient-centered approach and has been used by therapists in Central and South America to enhance motivation and commitment in substance use and risk reduction. Our pilot feasibility study utilized culturally tailored MI in physicians to target patients not retained in treatment in public and private clinics in Buenos Aires, Argentina. Results demonstrated that a physician-based MI intervention was feasible and effective in enhanced and sustained patient adherence, viral suppression, and patient-physician communication and attitudes about treatment among these patients at 6 and 9 months post baseline.

METHODS/DESIGN

This clinical trial seeks to extend these findings in public and private clinics in four urban population centers in Argentina, in which clinics (n = 6 clinics, six MDs per clinic site) are randomized to experimental (physician MI Intervention) (n = 3) or control (physician Standard of Care) (n = 3) conditions in a 3:3 ratio. Using a cluster randomized clinical trial design, the study will test the effectiveness of a physician-based MI intervention to improve and sustain retention, adherence, persistence, and viral suppression among "challenging" patients (n = 420) over 24 months.

DISCUSSION

Results are anticipated to have significant public health implications for the implementation of MI to re-engage and retain patients in HIV treatment and care and improve viral suppression through high levels of medication adherence.

Sexual risk behaviour among HIV-infected women in the first twelve months after delivery in South Africa

This study aimed to assess sexual risk behaviour and its social correlates in HIV-infected women living in rural South Africa at six and twelve months post-partum. Participants were 699 HIV-positive women recruited prenatally by systematic sampling from twelve community health centres in Mpumalanga province, South Africa (mean age = 28.4 years, SD = 5.7; married =41.1%; serodiscordant or unknown partner status = 74.9%). They self-reported on their sexual activity six to twelve months after delivery; including use of condoms and partner involvement. Generalised linear mixed models were utilised to estimate unsafe sex outcomes from a prevention of mother to child transmission (PMTCT) intervention, socio-demographic factors, disclosure, and male involvement. About 20% of sexually active women in the past week had used condoms inconsistently at six and twelve months after delivery. Moreover, 16% and 18% of the women had not used a condom at last sex and 11% and 13% had unprotected sex with HIV-uninfected or unknown-status partners following delivery at six and twelve months, respectively. Higher inconsistent condom use was likely with lower male involvement. Promotion of condom use post-partum, as well as male involvement in sexual decisions, are important for safer sex post-partum by seropositive women.

Infant Development and Pre- and Post-partum Depression in Rural South African HIV-Infected Women

HIV-exposed infants born to depressed women may be at risk for adverse developmental outcomes. Half of HIV-infected women in rural South Africa (SA) may suffer from pregnancy-related depression. This pilot study examined the impact of depression in HIV-infected women in rural SA on infant development. Mother-infant dyads (N = 69) were recruited in rural SA. Demographics, HIV disclosure, depression, male involvement, and alcohol use at baseline (18.35 ± 5.47 weeks gestation) were assessed. Male involvement, depression, infant HIV serostatus and development were assessed 12 months postnatally. Half of the women (age = 29 ± 5) reported depression prenatally and one-third reported depression postnatally. In multivariable logistic regression, not cohabiting with their male partner, nondisclosure of HIV status, and postnatal depression predicted cognitive delay; decreased prenatal male involvement predicted delayed gross motor development (ps < 0.05). Assessing pregnancy-related depression among HIV-infected women and infant development and increasing male involvement may reduce negative developmental outcomes among HIV-exposed or infected infants.

Reproductive decision-making among postpartum HIV-infected women in rural South Africa

Despite pregnancy spacing recommendations to optimize health outcomes among mothers and neonates, unplanned pregnancy in sub-Saharan Africa is common among women living with human immunodeficiency virus (HIV) (WLHIV). This study examined factors associated with reproductive decision-making among WLHIV to inform pregnancy-planning interventions. WLHIV in rural South Africa (n = 165) were assessed at 12 months postpartum. The relative importance of factors associated with reproductive decision-making was estimated. Women were a mean of 28 years old (SD = 5.71). Risk of mother-to-child transmission (MTCT) of HIV (Mean = 0.43; SD = 0.33) had the greatest impact on decision-making, followed by partners' desires (M = 0.22; SD = 0.18), family preferences (M = 0.18; SD = 0.13), and community opinion (M = 0.17; SD = 0.13). MTCT was most important to women with greater HIV knowledge. However, WLHIV who had been diagnosed with HIV for a longer time placed more emphasis on partner preference and community opinion, and less importance on MTCT risk. Prevention of mother-to-child transmission (PMTCT) was less important to women experiencing intimate partner violence and those with depression. Findings highlight the need for tailored, focused interventions to support the unique circumstances of WLHIV and support the inclusion of families and/or partners in the counseling process. Results underscore the need for perinatal preconception counseling for women during routine HIV care.

Suicidality among nonadherent patients living with HIV in Buenos Aires, Argentina: prevalence and correlates

Of those in the general population hospitalized for suicidal ideation and suicide attempts in Argentina, many reattempt suicide and are readmitted. However, few studies in Argentina have examined suicidal ideation and suicide-related behaviors among people living with HIV (PLHIV) and none have examined these factors among nonadherent PLHIV, though the prevalence of suicidal ideation in this group may be higher than in the general population and also than in other groups of PLHIV. This study of PLHIV in Buenos Aires, Argentina, examined the correlates of suicidal ideation in nonadherent PLHIV. Nonadherent patients with HIV (N = 118) were recruited from two clinics providing outpatient healthcare services to PLHIV in Buenos Aires, Argentina. Participants completed assessments on demographic characteristics, depression and suicidality, stigma, and self-efficacy. Participants were HIV-infected men (51%) and women (49%) with a median age of 40 years (IQR = 11). About half had completed high school or more, two-thirds were employed, and had a mean monthly income of 4196.79 (SD = 3179.64) Argentine pesos (USD$221). Thirty-three (28% [95% CI 20.3, 37.3]) participants reported suicidal ideation in the past two weeks, and one-third (35.6% [27.1, 44.9]) reported lifetime suicidal ideation. In bivariate analyses, attending a public clinic, being female, younger, unemployed, and experiencing greater stigma and depression were associated with suicidal ideation. In multivariable logistic regression, stigma interacted with the number of years since HIV diagnosis to predict suicidal ideation. The impact of stigma on suicidal ideation decreased with time since HIV diagnosis, suggesting that suicidal ideation may arise following HIV diagnosis due to perception of HIV-related stigma. Interventions to reduce perceived stigma during the period following HIV diagnosis may reduce suicidal ideation in this population. Organizational initiatives that explore HIV stigma microagressions in the healthcare setting may be needed to optimize health outcomes.

Fertility intentions of prenatal and postpartum HIV-positive women in primary care in Mpumalanga province, South Africa: a longitudinal study

Introduction

This study aimed to assess fertility intentions (planning to have more children in the future) and associated factors among pregnant and postpartum HIV positive women in rural South Africa.

Methods

In a longitudinal study, as part of a prevention of mother to child transmission (PMTCT) intervention trial, 699 HIV positive prenatal women, were systematically recruited and followed up at 6 months and 12 months postpartum (retention rate = 59.5%).

Results

At baseline, 32.9% of the women indicated fertility intentions and at 12 months postnatal, 120 (28.0%) reported fertility intentions. In longitudinal analyses, which included time-invariant baseline characteristics predicting fertility intention over time, not having children, having a partner with unknown/HIV-negative status, and having disclosed their HIV status to their partner, were associated with fertility intentions. In a model with time-varying covariates, decreased family planning knowledge, talking to a provider about a future pregnancy, and increased male involvement were associated with fertility intentions.

Conclusion

Results support ongoing perinatal family planning and PMTCT education.

Prevalence and Factors Associated with Fixed-Dose Combination Antiretroviral Drugs Adherence among HIV-Positive Pregnant Women on Option B Treatment in Mpumalanga Province, South Africa

The possibility for all babies to be born and remain HIV-negative for the first year of life is achievable in South Africa. HIV-positive mothers' adherence to their antiretroviral medication is one of the crucial factors to achieve this target. Cross-sectional data were collected at 12 community health centres, over 12 months (2014-2015), from 673 HIV-positive women, less than 6 months pregnant, attending antenatal care, and on Option B treatment. Adherence measures included the Adults AIDS Clinical Trials Group (AACTG) four-day measure, as well as the Visual Analog Scale (VAS) seven-day measure. Bivariate analyses and multivariate logistic regressions are presented. 78.8% of respondents were adherent on AACTG, while 68.8% reported VAS adherence. Bivariate analyses for increased adherence show significant associations with older age, less/no alcohol usage, disclosure of HIV status, higher HIV knowledge, no desire to avoid ARV side effects, low stigma, and low depression. AACTG showed a negative association with intimate partner violence. Multivariable logistic regression on AACTG and VAS adherence rates resulted in unique contributions to increased adherence of older age, less/no alcohol usage, higher HIV knowledge, lack of depression, and non-disclosure. Programs targeting closer side effect monitoring, HIV disclosure, pre-natal depression, alcohol intake, and HIV knowledge need consideration.

A cluster randomized controlled trial of lay health worker support for prevention of mother to child transmission of HIV (PMTCT) in South Africa

BACKGROUND

We evaluate the impact of clinic-based PMTCT community support by trained lay health workers in addition to standard clinical care on PMTCT infant outcomes.

METHODS

In a cluster randomized controlled trial, twelve community health centers (CHCs) in Mpumalanga Province, South Africa, were randomized to have pregnant women living with HIV receive either: a standard care (SC) condition plus time-equivalent attention-control on disease prevention (SC; 6 CHCs; n  = 357), or an enhanced intervention (EI) condition of SC PMTCT plus the "Protect Your Family" intervention (EI; 6 CHCs; n  = 342). HIV-infected pregnant women in the SC attended four antenatal and two postnatal video sessions and those in the EI, four antenatal and two postnatal PMTCT plus "Protect Your Family" sessions led by trained lay health workers. Maternal PMTCT and HIV knowledge were assessed. Infant HIV status at 6 weeks postnatal was drawn from clinic PCR records; at 12 months, HIV status was assessed by study administered DNA PCR. Maternal adherence was assessed by dried blood spot at 32 weeks, and infant adherence was assessed by maternal report at 6 weeks. The impact of the EI was ascertained on primary outcomes (infant HIV status at 6 weeks and 12 months and ART adherence for mothers and infants), and secondary outcomes (HIV and PMTCT knowledge and HIV transmission related behaviours). A series of logistic regression and latent growth curve models were developed to test the impact of the intervention on study outcomes.

RESULTS

In all, 699 women living with HIV were recruited during pregnancy (8-24 weeks), and assessments were completed at baseline, at 32 weeks pregnant (61.7%), and at 6 weeks (47.6%), 6 months (50.6%) and 12 months (59.5%) postnatally. Infants were tested for HIV at 6 weeks and 12 months, 73.5% living infants were tested at 6 weeks and 56.7% at 12 months. There were no significant differences between SC and EI on infant HIV status at 6 weeks and at 12 months, and no differences in maternal adherence at 32 weeks, reported infant adherence at 6 weeks, or PMTCT and HIV knowledge by study condition over time.

CONCLUSION

The enhanced intervention administered by trained lay health workers did not have any salutary impact on HIV infant status, ART adherence, HIV and PMTCT knowledge. Trial registration clinicaltrials.gov: number NCT02085356.

The Achilles' heel of prevention to mother-to-child transmission of HIV: Protocol implementation, uptake, and sustainability

The Joint United Nations Programme on HIV and AIDS proposed to reduce the vertical transmission of HIV from ∼72,200 to ∼8300 newly infected children by 2015 in South Africa (SA). However, cultural, infrastructural, and socio-economic barriers hinder the implementation of the prevention of mother-to-child transmission (PMTCT) protocol, and research on potential solutions to address these barriers in rural areas is particularly limited. This study sought to identify challenges and solutions to the implementation, uptake, and sustainability of the PMTCT protocol in rural SA. Forty-eight qualitative interviews, 12 focus groups discussions (n = 75), and one two-day workshop (n = 32 participants) were conducted with district directors, clinic leaders, staff, and patients from 12 rural clinics. The delivery and uptake of the PMTCT protocol was evaluated using the Consolidated Framework for Implementation Research (CFIR); 15 themes associated with challenges and solutions emerged. Intervention characteristics themes included PMTCT training and HIV serostatus disclosure. Outer-setting themes included facility space, health record management, and staff shortage; inner-setting themes included supply use and availability, staff-patient relationship, and transportation and scheduling. Themes related to characteristics of individuals included staff relationships, initial antenatal care visit, adherence, and culture and stigma. Implementation process themes included patient education, test results delivery, and male involvement. Significant gaps in care were identified in rural areas. Information obtained from participants using the CFIR framework provided valuable insights into solutions to barriers to PMTCT implementation. Continuously assessing and correcting PMTCT protocol implementation, uptake and sustainability appear merited to maximize HIV prevention.

Subclinical Atherosclerosis Among Young and Middle-Aged Adults Using Carotid Intima-Media Thickness Measurements

OBJECTIVES

The presence of atherosclerotic plaque in the carotid arteries is a strong predictor of cardiovascular disease (CVD). Research and data on CVD risk have been derived primarily from individuals aged 55 years or older, and assessment of CVD risk among young and middle-aged adults seldom has been studied. The use of ultrasonography to measure carotid intima-media thickness (IMT) and carotid plaque appears to have utility to detect subclinical atherosclerosis in asymptomatic adults. This study evaluated the presence of carotid plaque using ultrasonography among healthy young and middle-aged adults.

METHODS

Participants were men and women recruited in Miami, Florida, and were 18 to 50 years old with no history of CVD. Participants underwent a general physical examination and carotid artery ultrasonography to evaluate carotid IMT and carotid plaque.

RESULTS

From a total of 173 participants with a mean age of 34 years (standard deviation 8.9), 21.0% (95% confidence interval [CI] 15.0-27.2) were identified as having carotid plaque. IMT values ranged from 0.49 to 1.03 mm, with a mean value of 0.70 mm (standard deviation 0.09). In multivariable logistic regression older age (adjusted odds ratio [AOR] 1.08, 95% CI 1.01-1.16, P = 0.024) and cigarette smoking (AOR 2.67, 95% CI 1.02-7.00, P = 0.045) were associated with plaque, after controlling for IMT (AOR 2.55, 95% CI 1.40-4.65, P = 0.002).

CONCLUSIONS

Traditional CVD risk factors such as those evaluated in this study may fail to provide adequate predictive value of carotid atherosclerosis in younger populations with no history of CVD, because the majority of traditional risk factors identified in previous research were not associated with carotid plaque in this young sample. Further research assessing nontraditional risk factors among asymptomatic individuals is required, and the evaluation of IMT as an intervention tool to detect CVD risk in these asymptomatic populations is warranted.

Let us fight and support one another: adolescent girls and young women on contributors and solutions to HIV risk in Zambia

In Zambia, adolescent girls and young women (AGYW) are disproportionately affected by human immunodeficiency virus (HIV), social, cultural and economic factors making them particularly vulnerable. This study was designed to understand the context in which AGYW are at risk and to identify perceived drivers of the epidemic and potential strategies to reduce HIV risk. Focus group discussions were conducted with AGYW in Zambian districts with the highest HIV prevalence from February through August 2016. The focus group guide addressed HIV risk factors and strategies for HIV prevention in AGYW. Focus group discussions were recorded, translated and transcribed, themes identified and responses coded. Results suggest that gender inequality undermined potentially protective factors against HIV among AGYW. Poverty and stigmatization were major barriers to accessing available HIV prevention services as well as primary risk factors for HIV infection. Sponsorship to support AGYW school attendance, programs for boys and girls to foster gender equality and financial assistance from the government of Zambia to support AGYW most in need were proposed as strategies to reduce HIV risk. Results highlight the utility of using community-based research to guide potential interventions for the affected population. Future research should explore the use of multilevel interventions to combat HIV among AGYW.

Adolescent girls and young women living with HIV: preconception counseling strategies

Background

Rates of pregnancy among women living with HIV are similar to those in the general population. Unintended pregnancies are also common, and among adolescents and young women perinatally infected (PHIV+) or behaviorally infected (BHIV+) with HIV, planning for both conception and contraception is an important element of HIV care that may be neglected. This pilot study examined the influence of intervention strategies targeting fertility planning, safer conception practices and patient-provider communication. It was hypothesized that preconception counseling interventions would enhance reproductive knowledge, planning and practices, as well as stimulate discussion with providers regarding conception.

Methods

Adolescent girls and young women (N=34) perinatally (n=21) or behaviorally (n=13) infected with HIV, aged 16–29 years, were recruited from urban South Florida, and completed measures of reproductive knowledge, sexual practices and fertility intentions. Participants were randomized to condition, ie, video presentation plus Motivational Interviewing (MI), MI only, control.

Results

The average age of women was 22 years (SD =3.27), and the majority of them were African American. Levels of depression were higher among BHIV+ compared to PHIV+ at baseline and 6 months. Pregnancy knowledge (pregnancy, safe conception and pregnancy planning) and the proportion of those engaging in birth control planning (condom use, long-term birth control, patient-provider discussions on preventing pregnancy and fertility desires) were similar between conditions at post-intervention and 6 months. Bayes factors indicated that the data were insensitive with regard to differences between conditions, limiting support for both the null and alternative hypotheses.

Conclusion

The impact of interventions used in this study to stimulate pregnancy planning was inconclusive. Results suggest that pregnancy planning interventions may require greater intensity to influence sexual behavior in this population. Despite adequate reproductive knowledge, HIV-infected adolescent girls and young women may fail to engage in planning behavior.

HIV Knowledge and Risk among Zambian Adolescent and Younger Adolescent Girls: Challenges and Solutions

In sub-Saharan Africa, young women are at the highest risk of HIV infection. Comprehensive sexuality education (CSE) and open parent-child communication about sex have been shown mitigate risky sexual practices associated with HIV. This study aimed to identify sources of HIV prevention knowledge among young women aged 10-14 years and community-based strategies to enhance HIV prevention in Zambia. Focus group discussions were conducted with 114 young women in Zambian provinces with the highest rates (~20%) of HIV. Discussions were recorded, transcribed and coded, and addressed perceived HIV risk, knowledge and access to information. Participants reported that limited school-based sexuality education reduced the potential to gain HIV prevention knowledge, and that cultural and traditional practices promoted negative attitudes regarding condom use. Parent-child communication about sex was perceived to be limited; parents were described as feeling it improper to discuss sex with their children. Initiatives to increase comprehensive sexuality education and stimulate parental communication about sexual behavior were suggested by participants. Culturally tailored programmes aiming to increase parent-child communication appear warranted. Community-based strategies aimed at enhancing protective sexual behaviour among those most at risk are essential.
