RESUMEN

People living with HIV (PLHIV) in the United States (US) are more likely to experience traumatic events than non-affected peers. Sexual violence is a unique trauma that has important implications for HIV-related treatment and care. The aim of the current study was to examine links between sexual violence and Quality of Life (QoL) among PLHIV in South Carolina - a Southern state that is disproportionately impacted by the HIV epidemic. Specifically, we surveyed 402 PLHIV about their past exposure to sexual traumas and their current QoL across multiple domains. Results indicated that women living with HIV were more likely to have experienced sexual trauma than men. Participants with histories of sexual trauma reported poorer overall QoL, as well as less satisfaction with their health. Multiple regression analyses indicated that exposure to sexual violence was associated with lower QoL in four of six domains, including psychological functioning, independence, social relationships, and environment. Sexual trauma was not associated with physical health QoL in the current study. Surprisingly, sexual trauma was associated with higher spiritual QoL. Findings support the need to screen PLHIV for sexual trauma exposure, adopt trauma-informed practices, and ensure that all PLHIV have access to comprehensive psychological services when indicated.

RESUMEN

Ensuring the wellbeing of people living with HIV (PLWH) has become a significant public health concern in the era of highly active antiretroviral therapy. This study was to assess the quality of life (QoL) among PLWH in South Carolina (SC) and to examine the relationship between self-reported viral load (VL) suppression and their perceived QoL. In 2018, a cross-sectional survey was conducted among 402 PLWH from a large immunology clinic in SC. The WHOQoL brief version (WHOQoL-HIV-BREF) instrument with six domains (physical health, psychological health, social relations, independence, environmental health, and spirituality) and two specific questions (overall rate of QoL and satisfaction with health) were used. On a five-point scale, the participants rated their overall rating of QoL as good (mean = 4.07). The participants reported their psychological health as the highest (mean = 3.88) followed by environmental health (mean = 3.82), social relations (mean = 3.69), and independence (mean = 3.47). 71% reported an undetected VL. In multivariable analyses, self-awareness of undetected VL was significantly associated with satisfaction with health, psychological health, social relations, environmental health, but negatively associated with spirituality. These findings suggest that self-awareness of undetected VL had a significant impact on their perceived QoL beyond sociodemographic factors among PLWH who were linked to care in SC.

RESUMEN

BACKGROUND: The objective of this study was to determine if a school support intervention for adolescent orphans in Kenya had effects on mental health, a secondary outcome. METHODS: In this paper, we analyzed data from a 4-year cluster-randomized trial of a school support intervention (school uniforms, school fees, and nurse visits) conducted with orphaned adolescents in Siaya County, western Kenya, who were about to transition to secondary school. 26 primary schools were randomized (1:1) to intervention (410 students) or control (425 students) arms. The study was longitudinal with annual repeated measures collected over 4 years from 2011 to 2014. We administered five items from the 20-item Center for Epidemiologic Studies Depression Scale Revised, a self-reported depression screening instrument. RESULTS: The intervention prevented depression severity scores from increasing over time among adolescents recruited from intervention schools. There was no evidence of treatment heterogeneity by gender or baseline depression status. The intervention effect on depression was partially mediated by higher levels of continuous school enrollment among the intervention group, but this mediated effect was small. CONCLUSIONS: School support for orphans may help to buffer against the onset or worsening of depression symptoms over time, promoting resilience among an important at-risk population.

RESUMEN

Women and girls are disproportionately affected by HIV and other sexually transmitted infections (STIs) such as Herpes Simplex Virus type-2 (HSV-2) in Sub-Saharan Africa (SSA). Given this gender disparity and women's vulnerability to HIV/STIs, prevention efforts often target women, but relatively little attention has been paid to compare whether HIV interventions produce equal program effects across gender. The purpose of this study is to examine whether the school support intervention had equal program effects on study outcomes and biomarkers by gender among orphaned adolescents in Kenya. A randomized controlled trial was conducted to test whether keeping orphaned boys and girls in school reduced risky sexual behaviors and prevented HIV/HSV-2 infection in Kenya (N = 835). We collected four annual surveys and biomarkers measures of HIV and HSV-2 at Time 1 and Time 4. Regression analysis and multi-level linear mixed models were conducted, and t test with Satterthwaites' method for each regression coefficients was used to compare program effects by gender. There were substantial gender differences on risky sexual behaviors, HSV-2 infection, and gendered ideologies prior to intervention implementation. The school support intervention had significant gender-specific program impacts on HSV-2. The intervention females experienced a 36% increase in HSV-2 infection while intervention males experienced a 23% decrease after 3 years of program implementation. Differential program effects by gender on attitudes toward abstaining from sex were also found. More scientific research is needed to test whether HIV interventions produce equal program impacts by gender. Prevention programs should recognize gender-specific program effects and address individual, relational, and contextural factor that reinforce the gender disparity in HIV/HSV-2 risk.

RESUMEN

We evaluated 2 assays to detect antibodies to herpes simplex virus type 2 in dried blood spots prepared from blood specimens submitted to a reference laboratory in Kenya. Dried blood spots did not perform well with the Kalon herpes simplex virus type 2 assay. Focus HerpeSelect 2 was 98.8% sensitive and 98.9% specific with dried blood spots.

RESUMEN

Globally, significant progress has been made in primary school enrollment. However, there are millions of adolescents-including orphans in sub-Saharan Africa-who still experience barriers to remaining in school. We conducted a 4-year cluster randomized controlled trial (cRCT) (N = 835) in a high HIV prevalence area in western Kenya to test whether providing orphaned adolescents with a school support intervention improves their educational outcomes. The school support intervention consisted of directly paying tuition, exam fees, and uniform costs to primary and secondary schools for those students who remained enrolled. In addition, research staff monitored intervention participants' school attendance and helped to address barriers to staying in school. This school support intervention had significant positive impacts on educational outcomes for orphaned adolescents. Over the course of the study, school absence remained stable for intervention group participants but increased in frequency for control group participants. Intervention group participants were less likely to drop out of school compared to the control group. Furthermore, the intervention participants were more likely to make age-appropriate progression in grade, matriculate into secondary school, and achieve higher levels of education by the end of the study. The intervention also increased students' expectations of graduating from college in the future. However, we found no significant intervention impact on primary and secondary school test scores. Results from this cRCT suggest that directly covering school-related expenses for male and female orphaned adolescents in western Kenya can improve their educational outcomes.

RESUMEN

Orphaned adolescents are a large and vulnerable population in sub-Saharan Africa, at higher risk for HIV than non-orphans. Yet prevention of new infection is critical for adolescents since they are less likely than adults to enter and remain in treatment and are the only age group with rising AIDS death rates. We report process evaluation for a randomized controlled trial (RCT) testing support to stay in school (tuition, uniform, nurse visits) as an HIV prevention strategy for orphaned Kenyan adolescents. The RCT found no intervention effect on HIV/HSV-2 biomarker outcomes. With process evaluation, we examined the extent to which intervention elements were implemented as intended among the intervention group (N = 412) over the 3-year study period (2012-2014), the implementation effects on school enrollment (0-9 terms), and whether more time in school impacted HIV/HSV-2. All analyses examined differences as a whole, and by gender. Findings indicate that school fees and uniforms were fully implemented in 94 and 96% of cases, respectively. On average, participants received 79% of the required nurse visits. Although better implementation of nurse visits predicted more terms in school, a number of terms did not predict the likelihood of HIV/HSV-2 infection. Attending boarding school also increased number of school terms, but reduced the odds of infection for boys only. Four previous RCTs have been conducted in sub-Saharan Africa, and only one found limited evidence of school impact on adolescent HIV/HSV-2 infection. Our findings add further indication that the association between school support and HIV/HSV-2 prevention appears to be weak or under-specified.

RESUMEN

Educational achievement has important implications for the health and well-being of young women in sub-Saharan Africa. The authors assessed the effects of providing school support on educational outcomes of orphan girls in rural Zimbabwe. Data were from a randomized controlled trial offering the intervention group comprehensive schooling support and controls no treatment initially and then fees only. Results indicated comprehensive support reduced school dropout and absence but did not improve test scores. Providing support to orphan girls is promising for addressing World Health Organization Millennium Development Goals, but further research is needed about contextual factors affecting girls' school participation and learning.

RESUMEN

BACKGROUND: This paper examines the discordance between biological data of HIV and herpes simplex virus type 2 (HSV-2) infections and self-reported questionnaire responses among orphan adolescents in Western Kenya. METHODS: In 2011, 837 orphan adolescents from 26 primary schools were enrolled in an HIV prevention trial. At baseline, blood samples were drawn for HIV and HSV-2 infection biomarker testing, and participants completed an audio computer-assisted self-interviewing survey. RESULTS: Comparing biological data with self-reported responses indicated that 70% of HIV-positive (7 out of 10) and 64% of HSV-2-positive (18 out of 28 positive) participants reported never having had sex. Among ever-married adolescents, 65% (57 out of 88) reported never having had sex. Overall, 10% of study participants appeared to have inconsistently reported their sexual behaviour. Logistic regression analyses indicated that lower educational level and exam scores were significant predictors of inconsistent reporting. CONCLUSIONS: Our study demonstrates the discordance between infections measured by biomarkers and self-reports of having had sex among orphan adolescents in Kenya. In order to detect programme effects accurately in prevention research, it is necessary to collect both baseline and endline biological data. Furthermore, it is recommended to triangulate multiple data sources about adolescent participants' self-reported information about marriage and pregnancies from school records and parent/guardians to verify the information. Researchers should recognise potential threats to validity in data and design surveys to consider cognitive factors and/or cultural context to obtain more accurate and reliable information from adolescents regarding HIV/sexually transmitted infection risk behaviours.

RESUMEN

OBJECTIVES: Herpes simplex virus type 2 (HSV-2) biomarkers are often used in adolescent sub-Saharan HIV prevention studies, but evaluations of test performance and disclosure outcomes are rare in the published literature. Therefore, we investigated the proportion of ELISA-positive and indeterminate samples confirmed by western blot (WB), the psychosocial response to disclosure and whether reports of sexual behaviour and HSV-2 symptoms are consistent with WB confirmatory results among adolescent orphans in Kenya. METHODS: In 2011, 837 Kenyan orphan youth in grades 7 and 8 enrolled in an HIV prevention clinical trial with HSV-2 biomarker outcomes. We used a modified algorithm for the Kalon HSV-2 ELISA to improve specificity; positive and indeterminate results were WB tested. We developed culturally sensitive protocols for disclosing positive results, and documented psychosocial responses, reports of sexual contact and HSV-2 symptoms. RESULTS: 28 adolescents (3.3%) were identified as HSV-2 seropositive, six as indeterminate. Of these, 22 positive and all indeterminates were WB tested; 20 and 5, respectively, were confirmed positive. Most youth reported moderate brief stress after disclosure; 22% reported longer and more severe distress. Boys were more likely to be in the latter category. Self-reported virginity was highly inconsistent with WB-confirmed positives. CONCLUSIONS: The higher than manufacturer's cut-off for Kalon ELISA modestly reduced the rate of false-positive test results, but also increased false negatives. Investigators should consider the risk:benefit ratio in deciding whether or not to disclose HSV-2 results to adolescent participants under specific field conditions. TRIAL REGISTRATION NUMBER: NCT01501864.

RESUMEN

Research is limited on whether providing school support to female adolescent orphans mitigates their HIV risk disadvantage compared to other female adolescents. This paper examines 2011 Zimbabwe Demographic and Health Survey (ZDHS) HIV-related biomarker and behavior data for orphaned and nonorphaned rural adolescent females to compare findings from a similar sample participating in a randomized controlled trial (RCT) testing school support as HIV prevention. HIV status, marriage, pregnancy, sexual debut, school dropout, years of schooling, and socioeconomic status were analyzed with the combined data-sets. Bivariate analyses compared variables between RCT comprehensive intervention and delayed partial intervention conditions, and between ZDHS orphan and nonorphan groups. Multivariable analyses included a series of group comparisons as follows: ZDHS orphans vs. ZDHS nonorphans; RCT orphans in each condition vs. ZDHS nonorphans; RCT orphans in each condition vs. ZDHS orphans. Analyses methods accounted for the complex survey sampling design within each data-set. A total of 751 observations were included. All orphan groups had consistently higher odds of HIV infection than ZDHS nonorphans. ZDHS orphans had higher odds of marriage, pregnancy, and sexual debut than ZDHS nonorphans. Comprehensive intervention participants had lower odds of marriage, sexual debut, and school dropout than ZDHS nonorphans. RCT participants in both conditions had lower odds of marriage, sexual debut, and school dropout than ZDHS orphans. The findings indicate that orphans are at a distinct disadvantage to HIV risk compared to nonorphans, and much of this is likely related to vertical transmission. We found no evidence that provision of school fees to orphans will reduce their risk of HIV infection relative to nonorphans but further evidence that such programs may reduce risk behaviors including early sexual debut, child marriage, and school dropout. Further research is needed to determine how these programs can be sustainably scaled-up in resource-limited settings.

RESUMEN

Self-report of sexual behavior among adolescents is notoriously inconsistent, yet such measures are commonly used as outcomes for human immunodeficiency virus (HIV) prevention intervention trials. There has been a growing interest in the use of HIV and other sexually transmitted disease biomarkers as more valid measures of intervention impact in high HIV prevalence areas, particularly in sub-Saharan Africa. We examine the challenges, benefits, and feasibility of including HIV and herpes simplex virus type 2 (HSV-2) biomarker data, with details about different data collection and disclosure methods from two adolescent prevention trials in Kenya and Zimbabwe. In Kenya, whole blood samples were collected using venipuncture; adult guardians were present during biomarker procedures and test results were disclosed to participants and their guardians. In contrast, in Zimbabwe, samples were collected using finger pricks for dried blood spots (DBS); guardians were not present during biomarker procedures, and results were not disclosed to participants and/or their guardians. In both countries, prevalence in the study samples was low. Although the standard of care for testing for HIV and other sexually transmitted infections includes disclosure in the presence of a guardian for adolescents under age 18, we conclude that more research about the risks and benefits of disclosure to adolescents in the context of a clinical trial is needed. Notably, current serological diagnosis for HSV-2 has a low positive predictive value when prevalence is low, resulting in an unacceptable proportion of false positives and serious concerns about disclosing test results to adolescents within a trial. We also conclude that the DBS approach is more convenient and efficient than venipuncture for field research, although both approaches are feasible. Manufacturer validation studies using DBS for HSV-2, however, are needed for widespread use.

RESUMEN

OBJECTIVE: The paper examines the influence of religion on attitudes, behaviors, and HIV infection among rural adolescent women in Zimbabwe. DESIGN: We analyzed data from a 2007 to 2010 randomized controlled trial in rural eastern Zimbabwe testing whether school support can prevent HIV risk behaviors and related attitudes among rural adolescent orphan girls; supplementary data from the 2006 Zimbabwe Demographic and Health Survey (ZDHS) were also analyzed. The present study design is largely cross-sectional, using the most recent available survey data from the clinical trial to examine the association between religious affiliation and religiosity on school dropout, marriage, and related attitudes, controlling for intervention condition, age and orphan type. The ZDHS data examined the effect of religious denomination on marriage and HIV status among young rural women, controlling for age. RESULTS: Apostolic Church affiliation greatly increased the likelihood of early marriage compared to reference Methodist Church affiliation (odds ratio = 4.5). Greater religiosity independently reduced the likelihood of school dropout, increased gender equity attitudes and disagreement with early sex, and marginally reduced early marriage. Young rural Apostolic women in the ZDHS were nearly four times as likely to marry as teenagers compared to Protestants, and marriage doubled the likelihood of HIV infection. CONCLUSIONS: Findings contradict an earlier seminal study that Apostolics are relatively protected from HIV compared to other Christian denominations. Young Apostolic women are at increased risk of HIV infection through early marriage. The Apostolic Church is a large and growing denomination in sub-Saharan Africa and many Apostolic sects discourage medical testing and treatment in favor of faith healing. Since this can increase the risk of undiagnosed HIV infection for young married women and their infants in high prevalence areas, further study is urgently needed to confirm this emerging public health problem, particularly among orphan girls. Although empirical evidence suggests that keeping orphan girls in school can reduce HIV risk factors, further study of the religious context and the implications for prevention are needed.

RESUMEN

This cost-effectiveness study analyzes the cost per quality-adjusted life year (QALY) gained in a randomized controlled trial that tested school support as a structural intervention to prevent HIV risk factors among Zimbabwe orphan girl adolescents. The intervention significantly reduced early marriage, increased years of schooling completed, and increased health-related quality of life. By reducing early marriage, the literature suggests the intervention reduced HIV infection. The intervention yielded an estimated US$1,472 in societal benefits and an estimated gain of 0.36 QALYs per orphan supported. It cost an estimated US$6/QALY gained, about 1 % of annual per capita income in Zimbabwe. That is well below the maximum price that the World Health Organization (WHO) Commission on Macroeconomics and Health recommends paying for health gains in low and middle income countries. About half the girls in the intervention condition were boarded when they reached high school. For non-boarders, the intervention's financial benefits exceeded its costs, yielding an estimated net cost savings of $502 per pupil. Without boarding, the intervention would yield net savings even if it were 34 % less effective in replication. Boarding was not cost-effective. It cost an additional $1,234 per girl boarded (over the 3 years of the study, discounted to present value at a 3 % discount rate) but had no effect on any of the outcome measures relative to girls in the treatment group who did not board. For girls who did not board, the average cost of approximately 3 years of school support was US$973.

RESUMEN

OBJECTIVES: This study investigated the 8-year incidence and progression of hearing loss (HL) and its types and examined the risk factors for changes in HL. METHODS: This longitudinal cohort study analyzed data from the Korean Genome and Epidemiology Study (KoGES), an ongoing, prospective, community-based cohort study that has been conducted since 2001. Altogether, 1,890 residents of urban areas in Korea aged 45-75 years at time 1 (baseline) were included in the study. Pure-tone audiometry (PTA) testing was performed twice, at time 1 (2008-2009) and time 2 (2015-2018, follow-up), 8 years apart. HL grades were defined as seven mutually exclusive categories following the revised World Health Organization classification. Incidence was defined as PTA >20 dB HL in the better ear at time 2 among those without HL at time 1. Progression was defined as the progressive deterioration of HL among those with HL at time 1. The three types of HL constituted sensorineural (SNHL), conductive, and mixed HL. RESULTS: At time 1, 36.40% of patients were diagnosed with HL, which increased to 51.64% at time 2. The 8-year incidence of HL was 27.20%, and progressive deterioration of HL occurred in 23.11% of those with HL. SNHL was the most common type of HL, and its prevalence markedly increased at time 2. Multivariate analysis demonstrated that the incidence of HL was significantly associated with increasing age, male sex (odds ratio [OR], 1.73; 95% confidence interval [CI], 1.07-2.81), and diabetes mellitus (OR, 1.43; 95% CI, 1.04-1.96). Alcohol consumption was a risk factor for HL deterioration among those with HL at time 1. CONCLUSION: The prevalence and deterioration of HL were extremely high among older adults, and age was the strongest risk factor for these changes. Therefore, timely screening and intervention are necessary to prevent HL and delay its deterioration among older adults.

RESUMEN

We conducted a 2-year pilot randomized controlled trial (N = 105) in a high HIV-prevalence area in rural western Kenya to test whether providing young orphan adolescents with uniforms, school fees, and community visitors improves school retention and reduces HIV risk factors. The trial was a community intervention, limited to one community. In this paper, we examined intervention implementation and its association with outcomes using longitudinal data. We used both quantitative and qualitative methods to evaluate the community-based model for orphan HIV prevention, with recommendations for future studies. Despite promising effects after 1 year, GEE analyses showed null effects after 2 years. Volunteer community visitors, a key element of the intervention, showed little of the expected effect although qualitative reports documented active assistance to prevent orphans' school absence. For future research, we recommend capturing the transition to high school, a larger sample size, and biomarker data to add strength to the research design. We also recommend a school-based intervention approach to improve implementation and reduce infrastructure costs. Finally, we recommend evaluating nurses as agents for improving school attendance and preventing dropout because of their unique ability to address critical biopsychosocial problems.

RESUMEN

Objective: We assessed the collateral impact of the COVID-19 pandemic on healthcare service use among people with disabilities. Methods: We utilized the COVID-19 database from the Korean National Health Insurance Service claims from 2015 until June 2020. We included 5,850 people with disabilities and matched 5,850 without disabilities among those who were neither tested nor diagnosed with COVID-19. We used a quasi-experimental setting with a COVID-19 outbreak as an external event in a difference-difference estimation with matching controls. Results: Participants with disabilities recorded a larger decrease in the number of claims for total services (2.1 claims per 5 months) upon the COVID-19 pandemic's onset compared to those without disabilities (1.6 claims), and the difference-in-difference estimates were statistically significant (0.46 claims). The decline was driven by outpatient and emergency visits. The extent of the decline was large for the severe disability group overall. By disability type, those with a physical disability showed a statistically significant decline in the number of claims. Conclusion: The COVID-19 pandemic has had a collateral impact on people with disabilities' use of healthcare services. Continued assessment is needed regarding whether the collateral impact has been sustained or is following a different path.

RESUMEN

OBJECTIVES: Using a randomized controlled trial in rural eastern Zimbabwe, we tested whether comprehensive support to keep orphan adolescent girls in school could reduce HIV risk. METHODS: All orphan girls in grade 6 in 25 primary schools were invited to participate in the study in fall 2007 (n = 329). Primary schools were randomized to condition. All primary schools received a universal daily feeding program; intervention participants received fees, uniforms, and a school-based helper to monitor attendance and resolve problems. We conducted annual surveys and collected additional information on school dropout, marriage, and pregnancy rates. We analyzed data using generalized estimating equations over 3 time points, controlling for school and age at baseline. RESULTS: The intervention reduced school dropout by 82% and marriage by 63% after 2 years. Compared with control participants, the intervention group reported greater school bonding, better future expectations, more equitable gender attitudes, and more concerns about the consequences of sex. CONCLUSIONS: We found promising evidence that comprehensive school support may reduce HIV risk for orphan girls. Further study, including assessment of dose response, cost benefit, and HIV and herpes simplex virus 2 biomarker measurement, is warranted.

RESUMEN

This study aimed to examine the potential mediation effect of adherence self-efficacy on the associations between individual and neighborhood socioeconomic status and antiretroviral therapy adherence in a sample of 337 people living with HIV in South Carolina, United States. Results showed that there were no direct effects of individual or neighborhood socioeconomic status on antiretroviral therapy adherence, whereas both individual socioeconomic status and neighborhood socioeconomic status were associated with adherence self-efficacy, which in turn were related to antiretroviral therapy adherence. These findings suggest that interventions targeting adherence self-efficacy may improve antiretroviral therapy adherence among people living with HIV with low socioeconomic status or those living in socioeconomically disadvantaged neighborhoods.

RESUMEN

This study examines prevention practices and perceptions in U.S. schools since passage of federal No Child Left Behind (NCLB) legislation, using survey data from state education agencies (SEA) and a population-based sample of school districts. Only one third of U.S. public school districts rely on evidence-based prevention curriculum in middle schools. Funding from other sources and large size were positively associated with using evidence-based curricula. States and districts differed on their perceptions of high-priority activities, and neither supported the federal priority on student drug testing. The findings suggest that there is a disconnect between what NCLB says and what is funded.
