RESUMO

The relationship between food insecurity and transactional sex is well recognized, but less is known about this relationship among adolescents. We analyzed cross-sectional baseline data from 3,130 female secondary students aged 12-19 enrolled in a three-arm, cluster randomized controlled trial to examine the association between food insecurity and transactional sex. The explanatory variable was food security and the outcome was ever engaging in transactional sex. Over one quarter (28.7%) reported any food insecurity and 1.9% of all participants (9.6% of sexually active participants) reported ever engaging in transactional sex. In adjusted models, ever experiencing any food insecurity was associated with a higher prevalence of ever transactional sex (PR: 1.60; 95% CI: 1.02, 2.49) compared to little to no food insecurity. These results provide insight into potential predictors of higher-risk sexual behavior in Rwanda; they also provide policy-makers with populations with whom to intervene on upstream determinants of transactional sex, notably poverty and food insecurity.

RESUMO

BACKGROUND: Concerns about the interconnected relationship between HIV and mental health were heightened during the COVID-19 pandemic. This study assessed whether there were temporal changes in the mental health status of people living with HIV presenting for care in Shinyanga region, Tanzania. Specifically, we compared the prevalence of depression and anxiety before and during COVID-19, with the goal of describing the changing needs, if any, to person-centered HIV services. METHODS: We analyzed baseline data from two randomized controlled trials of adults initiating ART in Shinyanga region, Tanzania between April-December 2018 (pre-COVID-19 period, n = 530) and May 2021-March 2022 (COVID-19 period, n = 542), respectively. We compared three mental health indicators that were similarly measured in both surveys: loss of interest in things, hopelessness about the future, and uncontrolled worrying. We also examined depression and anxiety which were measured using the Hopkins Symptom Checklist-25 in the pre-COVID-19 period and the Patient Health Questionnaire-4 in the COVID-19 period, respectively, and classified as binary indicators per each scale's threshold. We estimated prevalence differences (PD) in adverse mental health status before and during the COVID-19 pandemic, using stabilized inverse probability of treatment weighting to adjust for underlying differences in the two study populations. RESULTS: We found significant temporal increases in the prevalence of feeling 'a lot' and 'extreme' loss of interest in things ['a lot' PD: 38, CI 34,41; 'extreme' PD: 9, CI 8,12)], hopelessness about the future [' a lot' PD: 46, CI 43,49; 'extreme' PD: 4, CI 3,6], and uncontrolled worrying [' a lot' PD: 34, CI 31,37; 'extreme' PD: 2, CI 0,4] during the COVID-19 pandemic. We also found substantially higher prevalence of depression [PD: 38, CI 34,42] and anxiety [PD: 41, CI 37,45]. CONCLUSIONS: After applying a quasi-experimental weighting approach, the prevalence of depression and anxiety symptoms among those starting ART during COVID-19 was much higher than before the pandemic. Although depression and anxiety were measured using different, validated scales, the concurrent increases in similarly measured mental health indicators lends confidence to these findings and warrants further research to assess the possible influence of COVID-19 on mental health among adults living with HIV.

RESUMO

INTRODUCTION: Stigma has inhibited public health practitioners' influence during the COVID-19 pandemic. We explore the experienced and anticipated stigma of people affiliated with a large university in the United States, using the Health Stigma and Discrimination Framework. METHODS: We conducted a qualitative secondary substudy of 20 people who tested SARS-CoV-2 positive and 10 who tested negative in the summer of 2020, selected from a study of 3,324 university students and employees. FINDINGS: No participants reported anticipated stigmatization prior to testing positive. However, eight of 20 participants recounted stigma marking (being marked by COVID-19 diagnosis or membership in a "high-risk" group) or manifestations of stigma after testing positive, including feelings of guilt or shame, and concerns about being judged as selfish or irresponsible. Three described being denied services or social interactions as a result of having had COVID-19, long after their infectiousness ended. Participants noted that clear public health messaging must be paired with detailed scientific information, rather than leaving people to resort to non-experts to understand the science. DISCUSSION: Public health messaging designed to mitigate spread of SARS-CoV-2 and protect the community may perpetuate stigma and exacerbate inequities. As a result, people may avoid testing or treatment, mistrust public health messaging, or even use risk-increasing behavior as coping mechanisms. IMPLICATIONS FOR PRACTICE: Intentional use of language that promotes equity and deters discrimination must be high priority for any COVID-19-related public health messaging. Partnership with community leaders to co-create programs and disseminate messaging is a critical strategy for reducing stigma, especially for historically mistreated groups.

RESUMO

BACKGROUND: HIV risk remains high among adolescent girls and young women (AGYW, ages 15-24) in Tanzania. Many AGYW experience stigma and provider bias at health facilities, deterring their use of HIV prevention services. Privately-owned drug shops, ubiquitous in many communities, may be an effective and accessible channel to deliver HIV prevention products to AGYW, including oral pre-exposure prophylaxis (PrEP) and the dapivirine vaginal ring. METHODS: In July-August 2019, we enrolled 26 drug shops in Shinyanga, Tanzania in an ongoing study to create "girl-friendly" drug shops where AGYW can access HIV self-testing and contraception. At baseline, all shop dispensers were given basic information about oral PrEP and the dapivirine ring and were asked about their interest in stocking each. During the next 3-5 months, we surveyed AGYW (n = 56) customers about their interest in oral PrEP and the ring. RESULTS: Among dispensers, the median age was 42 years and 77% were female. Overall, 42% of dispensers had heard of a medication for HIV prevention. Almost all dispensers reported some interest in stocking oral PrEP (92%) and the dapivirine ring (96%). Most (85%) reported they would provide oral PrEP to AGYW who requested it. Among AGYW customers, the median age was 17 years; 29% of AGYW were married or had a steady partner and 18% had children. Only 20% of AGYW had heard of a medication to prevent HIV, yet 64% and 43% expressed some interest in using oral PrEP and the dapivirine ring, respectively, after receiving information about the products. PrEP interest was higher among AGYW who were partnered and had children. CONCLUSIONS: Despite low prior awareness of PrEP among shop dispensers and AGYW, we found high levels of interest in oral PrEP and the dapivirine ring in both groups. Community-based drug shops represent a promising strategy to make HIV prevention more accessible to AGYW.

RESUMO

BACKGROUND: Many persons with active SARS-CoV-2 infection experience mild or no symptoms, presenting barriers to COVID-19 prevention. Regular temperature screening is nonetheless used in some settings, including university campuses, to reduce transmission potential. We evaluated the potential impact of this strategy using a prospective university-affiliated cohort. METHODS: Between June and August 2020, 2912 participants were enrolled and tested for SARS-CoV-2 by PCR at least once (median: 3, range: 1-9). Participants reported temperature and symptoms daily via electronic survey using a previously owned or study-provided thermometer. We assessed feasibility and acceptability of daily temperature monitoring, calculated sensitivity and specificity of various fever-based strategies for restricting campus access to reduce transmission, and estimated the association between measured temperature and SARS-CoV-2 test positivity using a longitudinal binomial mixed model. RESULTS: Most participants (70.2%) did not initially have a thermometer for taking their temperature daily. Across 5481 total person months, the average daily completion rate of temperature values was 61.6% (median: 67.6%, IQR: 41.8-86.2%). Sensitivity for SARS-CoV-2 ranged from 0% (95% CI 0-9.7%) to 40.5% (95% CI 25.6-56.7%) across all strategies for self-report of possible COVID-19 symptoms on day of specimen collection, with corresponding specificity of 99.9% (95% CI 99.8-100%) to 95.3% (95% CI 94.7-95.9%). An increase of 0.1 °F in individual mean body temperature on the same day as specimen collection was associated with 1.11 increased odds of SARS-CoV-2 positivity (95% CI 1.06-1.17). CONCLUSIONS: Our study is the first, to our knowledge, that examines the feasibility, acceptability, and effectiveness of daily temperature screening in a prospective cohort during an infectious disease outbreak, and the only study to assess these strategies in a university population. Daily temperature monitoring was feasible and acceptable; however, the majority of potentially infectious individuals were not detected by temperature monitoring, suggesting that temperature screening is insufficient as a primary means of detection to reduce transmission of SARS-CoV-2.

RESUMO

BACKGROUND: Rwandan adolescents have limited access to high-quality family planning and reproductive health (FP/RH) information and care to prevent unplanned pregnancy and HIV/STIs. In addition to the immediate implications for health and well-being, teenage pregnancy is a significant cause of school drop-out, limiting girls' future potential and employment opportunities. This study introduces a direct-to-consumer digital education program that uses storytelling to deliver age-appropriate FP/RH information and economic empowerment training to adolescents. It also facilitates access to high-quality, youth-friendly FP/RH care and products. We evaluate two different school-based models of its implementation to understand how to optimize the uptake of contraception and HIV testing among adolescents. METHODS: The study consists of two distinct phases. The first formative intervention design phase, conducted from 2016 to 2019, used a human-centered design methodology to develop the intervention alongside over 600 Rwandan adolescents, their parents, teachers, and healthcare providers. Through this methodology, we sought to maximize the fit between evidence-based practices (uptake of modern contraception and HIV testing) and the implementation context of adolescents in Rwanda. The second phase is an impact evaluation, in which we will use a Hybrid Trial Type 2 Effectiveness-Implementation study design to determine the overall effectiveness of this digital intervention as well as the relative effectiveness of the two different school-based implementation models. This takes the form of a 3-arm cluster-randomized non-inferiority trial, with a sample of 6000 youth aged 12-19 in 60 schools across 8 districts in Rwanda. Primary outcome measures include use of modern contraception, delayed initiation of childbearing, and uptake of HIV testing. DISCUSSION: This study will yield insights into not only whether this digital intervention is successful in achieving the intended sexual and reproductive health outcomes, but also which mechanisms are likely to drive this effectiveness. The methodologies used are broadly applicable to the design, implementation, and evaluation of other behavior-based health programs in low and middle-income countries.

RESUMO

Citizen groups, though celebrated during their sudden arrival on the lobbying scene, are vastly outnumbered by groups representing elite, occupationally based interests. Sensitive to the odds that nonoccupational groups face, this study asks what factors have allowed patient groups to form and become active in federal politics. Using three distinct data sets--a survey of patient groups, content analysis of group websites, and in-depth interviews with group representatives and policy makers in Washington, DC--this study assesses the activities of patient groups in the United States and argues that patient advocacy organizations garner stability from the relatively easy provision of selective and solidary benefits. Larger patient groups are especially likely to make use of these structural advantages to pursue congressional lobbying strategies. However, even these groups seek out noncompetitive, distributive political environments. Moreover, the study finds that patient groups rarely form coalitions across diseases, forgoing the potential to collectively speak for shared patient interests.

RESUMO

Background: Age-disparate relationships (ADR) place adolescent girls and young women (AGYW) at higher risk of unprotected sex and HIV infection; few studies have investigated ADR at first sex in sub-Saharan Africa. This study investigates ADR at first sex and its association with reproductive autonomy, reproductive empowerment, contraception coercion, and consent at first sex among female Rwandan youth. Methods: Cross-sectional data from a randomized trial (n = 5768) of in-school youth ages 12-19 at enrollment were analyzed with focus on those who reported sexual activity (n = 1319). General estimating equation linear models and Poisson models were used to estimate linear coefficients and prevalence ratios (PR), with 95% confidence intervals (CIs) estimated using robust standard errors. Results: Females reported a significantly higher average partner age gap than males by 2.43 years (2.90 years vs. 0.46 years, 95% CI: 2.01, 2.86). Overall, 23.4% (n = 102) of sexually active AGYW engaged in an ADR at first sex. The prevalence of non-consensual first sex was 60% higher among AGYW reporting ADR at first sex compared to AGYW reporting similar-aged partners (adjusted PR = 1.59, 95% CI: 1.25, 2.02). No association was found between ADR at first sex and reproductive autonomy, reproductive empowerment, or contraception coercion. Conclusions: Our results suggest a high prevalence of sexual violence among AGYW engaging in first sex with an age-disparate partner. However, we did not find evidence that ADR at first sex affects reproductive autonomy or empowerment within the first few years of sexual initiation. Further research is needed to explore the impact of ADR at first sex and longer-term trajectories of sexual behavior, empowerment and autonomy.

RESUMO

Importance: Nearly half of US states have restricted abortion access. Policy makers are exploring pathways to increase access to abortion and reproductive health care more broadly. Since 2016, California pharmacists could prescribe hormonal birth control, providing an opportunity to learn about the implementation of pharmacist-provided reproductive health care. Objective: To explore the feasibility of broadening pharmacist scope of practice to include prescribing medication abortion. Design, Setting, and Participants: A cross-sectional online survey was conducted from October 11 to December 20, 2022, among a convenience sample of California licensed community pharmacists to examine their attitudes toward, knowledge of, and confidence in prescribing hormonal birth control and reports of pharmacy-level practices. Main Outcomes and Measures: Descriptive analyses and log-binomial regression models were used to compare medication abortion and contraceptive provision attitudes by pharmacist and pharmacy characteristics. Results: Among the 316 pharmacists included in the analysis who worked at community pharmacies across California (mean [SD] age, 40.9 [12.0] years; 169 of 285 [59.3%] cisgender women; and 159 of 272 [58.5%] non-Hispanic Asian individuals), most (193 of 280 [68.9%]) indicated willingness to prescribe medication abortion to pharmacy clients if allowed by law. However, less than half were confident in their knowledge of medication abortion (139 of 288 [48.3%]) or their ability to prescribe it (115 of 285 [40.4%]). Pharmacists who indicated that providing access to hormonal birth control as a prescribing provider was important (263 of 289 [91.0%]) and were confident in their ability to prescribe it (207 of 290 [71.4%]) were 3.96 (95% CI, 1.80-8.73) times and 2.44 (95% CI, 1.56-3.82) times more likely to be willing to prescribe medication abortion and to express confidence in doing so, respectively. Although most pharmacists held favorable attitudes toward hormonal birth control, less than half (144 of 308 [46.8%]) worked in a pharmacy that provided prescriptions for hormonal birth control, and 149 who did not reported barriers such as lack of knowledge or training (65 [43.6%]), insufficient staff or time to add new services (58 [38.9%]), and lack of coverage for services (50 [33.6%]). Conclusions and Relevance: The findings of this cross-sectional survey study of California pharmacists suggest that most pharmacists were willing to prescribe medication abortion. However, future efforts to expand pharmacists' scope of practice should include training to increase knowledge and confidence in prescribing medication abortion. Pharmacy-level barriers to hormonal birth control prescription, such as insurance coverage for pharmacist effort, should also be addressed, as they may serve as barriers to medication abortion access.

RESUMO

BACKGROUND: Economic incentives can improve clinical outcomes among in-care people living with HIV (PLHIV), but evidence is limited for their effectiveness among out-of-care PLHIV or those at risk of disengagement. We propose a type 1 hybrid effectiveness-implementation study to advance global knowledge about the use of economic incentives to strengthen the continuity of HIV care and accelerate global goals for HIV epidemic control. METHODS: The Rudi Kundini, Pamoja Kundini study will evaluate two implementation models of an economic incentive strategy for supporting two groups of PLHIV in Tanzania. Phase 1 of the study consists of a two-arm, cluster randomized trial across 32 health facilities to assess the effectiveness of a home visit plus one-time economic incentive on the proportion of out-of-care PLHIV with viral load suppression (< 1000 copies/ml) 6 months after enrollment (n = 640). Phase 2 is an individual 1:1 randomized controlled trial designed to determine the effectiveness of a short-term counseling and economic incentive program offered to in-care PLHIV who are predicted through machine learning to be at risk of disengaging from care on the outcome of viral load suppression at 12 months (n = 692). The program includes up to three incentives conditional upon visit attendance coupled with adapted counselling sessions for this population of PLHIV. Consistent with a hybrid effectiveness-implementation study design, phase 3 is a mixed methods evaluation to explore barriers and facilitators to strategy implementation in phases 1 and 2. Results will be used to guide optimization and scale-up of the incentive strategies, if effective, to the larger population of Tanzanian PLHIV who struggle with continuity of HIV care. DISCUSSION: Innovative strategies that recognize the dynamic process of lifelong retention in HIV care are urgently needed. Strategies such as conditional economic incentives are a simple and effective method for improving many health outcomes, including those on the HIV continuum. If coupled with other supportive services such as home visits (phase 1) or with tailored counselling (phase 2), economic incentives have the potential to strengthen engagement among the subpopulation of PLHIV who struggle with retention in care and could help to close the gap towards reaching global "95-95-95" goals for ending the AIDS epidemic.

RESUMO

BACKGROUND: Emergency departments (EDs) provide care to patients at increased risk for acquiring HIV, and for many of them, the ED serves as their sole point of entry into the healthcare system. We implemented the HIV PreventED Program to increase access to HIV prevention services for ED patients. SETTING: ED in Oakland, CA with an annual census of 57,000 visits. METHODS: This cross-sectional study evaluated the first 9 months of the HIV PreventED Program. In this program, a navigator surveyed adult ED patients who tested HIV negative to determine their risk for acquiring HIV infection, incorporating HIV prevention counseling into their assessments. Patients at higher risk for acquiring HIV were referred to outpatient prevention services, if interested. The primary outcome measure was the number and proportion of ED patients at higher risk for acquiring HIV who followed up for outpatient prevention services. RESULTS: In this study, 1233 patients who tested HIV negative were assessed by the navigator and received ED-based HIV prevention counseling. Of these, 193 (15.7%) were identified at higher risk and offered an outpatient referral for prevention services, of which 104 accepted (53.9%), 23 (11.9%) attended the referral, and 13 (6.7%) were prescribed preexposure prophylaxis (PrEP). The median time to linkage was 28 days (interquartile range 15-41 days). CONCLUSION: A navigator focused on providing ED-based HIV prevention counseling and linkage to outpatient services is feasible. Strategies to more efficiently identify ED patients at higher risk for HIV acquisition, such as automated identification of risk data from the electronic health record, and policies to improve follow-up and the receipt of PrEP, such as same-day PrEP initiation, should be prospectively evaluated.

RESUMO

INTRODUCTION: Adverse sexual and reproductive health (SRH) outcomes, such as unplanned pregnancies and HIV infection, disproportionately affect adolescent girls and young women (AGYW; aged 15-24 years) in east Africa. Increasing uptake of preventive SRH services via innovative, youth-centred interventions is imperative to addressing disparities in SRH outcomes. METHODS AND ANALYSIS: From 2018 to 2019, we used human-centred design to co-develop a theoretically driven HIV and pregnancy prevention intervention for AGYW at private drug shops called Accredited Drug Dispensing Outlets (ADDOs) in Tanzania. The result, Malkia Klabu (Queen Club), was a customer loyalty programme designed to strengthen ADDOs' role as SRH providers while encouraging uptake of critical SRH prevention products among AGYW. Malkia Klabu members had access to free contraceptives and oral HIV self-test (HIVST) kits and earned punches on a loyalty card for other shop purchases; punches were redeemable for small prizes. Our pilot among 40 shops showed that intervention ADDOs had higher AGYW patronage and distributed more HIVST kits and contraceptives to AGYW relative to business-as-usual (ie, client purchasing) comparison shops. We will conduct a cluster-randomised controlled trial (c-RCT) among 120-140 ADDOs in 40 health catchment areas in Shinyanga and Mwanza Regions (Lake Zone), Tanzania. ADDO shop recruitment includes a 1-month run-in with a tablet-based electronic inventory management system for tracking shop transactions, followed by enrolment, randomisation and a 24-month trial period. Our c-RCT evaluating the human-centred design-derived intervention will assess population impact on the primary outcomes of HIV diagnoses and antenatal care registrations, measured with routine health facility data. We will also assess secondary outcomes focusing on mechanisms of action, evaluate programme exposure and AGYW behaviour change in interviews with AGYW, and assess shop-level implementation strategies and fidelity. ETHICS AND DISSEMINATION: Ethical approval was granted from both the University of California, San Francisco and the Tanzanian National Institute for Medical Research. Study progress and final outcomes will be posted annually to the National Clinical Trials website; study dissemination will occur at conferences, peer-reviewed manuscripts and local convenings of stakeholders. TRIAL REGISTRATION NUMBER: NCT05357144.

RESUMO

PURPOSE: CyberRwanda is a digital health intervention designed to increase knowledge of family planning and reproductive health (FP/RH) and access to youth-friendly services in Rwanda. METHODS: Sixty schools in eight districts were randomized 1:1:1 to one of two CyberRwanda implementation models-self-service (tablet-only) or facilitated (tablet, activity booklet, peer facilitators)-or to control. Students aged 12-19 years were randomly selected to participate. Baseline and 12-month midline surveys assessed intermediate (secondary) outcomes of FP/RH and HIV knowledge, attitudes/beliefs, self-efficacy, and behavior. Prevalence differences (PDs) were estimated using generalized linear mixed models. RESULTS: There were 5,767 midline participants (51% female, mean/median age: 16 years, 29.9% sexually active). Those in CyberRwanda schools had higher knowledge of emergency contraception (57.3% vs. 47.5%, PD: 0.09, 95% confidence interval [CI]: 0.05-0.13); greater confidence in providing consent (73.3% vs. 68.1%, PD: 0.05, 95% CI: 0.01-0.08), negotiating partner's contraceptive use (88.3% vs. 85.0%, PD: 0.03, 95% CI: 0.01-0.06), and accessing/using contraceptive services (95.6% vs. 91.8%, PD: 0.03, 95% CI: 0.02-0.05); and more favorable views on FP/RH services (54.5% vs. 48.5%, PD: 0.06, 95% CI: 0.02-0.11) and condoms (76.9% vs. 71.3%, PD: 0.06, 95% CI: 0.03-0.08) compared to control. No significant differences in HIV/fertility knowledge, confidence in accessing HIV testing, or condom use were observed. DISCUSSION: CyberRwanda increased FP/RH knowledge, supportive attitudes/beliefs, self-efficacy, and behavior at 12 months. The 24-month endline analysis will reveal whether CyberRwanda's benefits on intermediate outcomes result in changes to the primary outcomes, including contraception use and childbearing.

RESUMO

BACKGROUND: Human herpesvirus 8 (HHV-8) is endemic in Uganda and transmissible by blood. We evaluated mortality following transfusion of HHV-8 antibody-positive blood. METHODS: In a hospital-based, observational, prospective cohort study with a 6-month follow-up, we examined the effect of HHV-8 antibody-positive blood on transfusion recipients surviving at least 7 days. RESULTS: Of 1092 recipients, 471 (43.1%) were transfused with HHV-8 antibody-positive blood. Median age was 1.8 years (range, 0.1-78); 111 (10.2%) died during follow-up. After adjusting for confounders (increasing age, human immunodeficiency virus infection, illness other than malaria, receipt of multiple transfusions), recipients of HHV-8 antibody-positive blood stored ≤4 days ("short-stored") were more likely to die than recipients of HHV-8 antibody-negative blood (adjusted hazards ratio [AHR], 1.92; 95% confidence interval [CI], 1.21-3.05; P = .01). The AHR of the effect of each additional short-stored HHV-8 antibody-positive transfusion was 1.79 (95% CI, 1.33-2.41; P = .001). CONCLUSIONS: Transfusion with short-stored HHV-8 antibody-positive blood was associated with an increased risk of death. Further research is warranted to determine if a causal pathway exists and to verify the observed association between acute HHV-8 infection and premature mortality.

RESUMO

OBJECTIVES: To examine how sales of sexual and reproductive health (SRH) products varied among pharmacies in Kenya using administrative data, leveraging natural variation in the COVID-19 pandemic and accompanying policy restrictions between 2019 and 2021. DESIGN AND SETTING: Ecological study of pharmacies in Kenya. PARTICIPANTS: 761 pharmacies using the Maisha Meds product inventory management system (capturing 572 916 products sold). OUTCOMES: Sales quantity, price and revenue of SRH products sold per pharmacy per week. RESULTS: COVID-19 deaths were associated with a -2.97% (95% CI -3.82%, -2.11%) decrease in sales quantity, a 1.09% (95% CI 0.44%, 1.72%) increase in sales price and a -1.89% (-1.00%, -2.79%) decrease in revenues per pharmacy per week. Results were similar when considering new COVID-19 cases (per 1000) and the Average Policy Stringency Index. Results differed substantially between individual SRH products-a large decrease in sales quantity in pregnancy tests, injectables and emergency contraception, a modest decrease in condoms and no change in oral contraception. Sales price increases were similarly varied; four of the five most sold products were revenue neutral. CONCLUSIONS: We found a robust negative association between SRH sales at pharmacies in Kenya and COVID-19 reported cases, deaths and policy restriction. Although our data cannot definitively point to reduced access, existing evidence from Kenya regarding unchanged fertility intentions, increases in unintended pregnancies and reported reasons for non-use of contraceptives during COVID-19 suggests a prominent role of reduced access. While policymakers may have a role in sustaining access, their role may be limited by broader macroeconomic problems, such as global supply chain disruptions and inflation, during supply shocks.

RESUMO

PURPOSE: Understanding the timing of sexual debut is critical for informing sexual and reproductive health interventions. We investigated sexual behavior and early sexual debut among Rwandan youth. METHODS: We conducted a cross-sectional analysis of data from a cluster-randomized trial with 6079 students ages 12-19 years in Rwanda. We examined predictors of early sexual debut (<15 years) using logistic regression to estimate odds ratios and factors associated with the timing of first sex using Cox models to estimate hazard ratios. Interpretations of sex were also explored. RESULTS: Participants were 15 years and 51.5% female on average; 1723 (28.3%) reported sexual activity. Among the 1320 participants who provided an age of sexual debut, 51.4% reported sex at ≤12 years and 75.7% at<15 years. Males had a higher odds of early sexual debut (adjusted odds ratio: 2.40; 95% CI: 1.99, 2.90) and a higher hazard of sex occuring at an earlier age than females (adjusted hazard ratio: 1.91; 95% CI: 1.67, 2.20). One-third of participants considered "sexual intercourse" to include kissing, touching, or masturbation. CONCLUSIONS: Sex at ≤12 years was frequently reported, indicating that interventions facilitating access to youth-friendly sexual and reproductive health services are necessary before age 12. Validation studies are needed to evaluate how interpretations of sexual intercourse influence the assessment of sexual activity. CLINICAL TRIAL: NCT04198272.

RESUMO

OBJECTIVES: To identify incident SARS-CoV-2 infections and inform effective mitigation strategies in university settings, we piloted an integrated symptom and exposure monitoring and testing system among a cohort of university students and employees. DESIGN: Prospective cohort study. SETTING: A public university in California from June to August 2020. PARTICIPANTS: 2180 university students and 738 university employees. PRIMARY OUTCOME MEASURES: At baseline and endline, we tested participants for active SARS-CoV-2 infection via quantitative PCR (qPCR) test and collected blood samples for antibody testing. Participants received notifications to complete additional qPCR tests throughout the study if they reported symptoms or exposures in daily surveys or were selected for surveillance testing. Viral whole genome sequencing was performed on positive qPCR samples, and phylogenetic trees were constructed with these genomes and external genomes. RESULTS: Over the study period, 57 students (2.6%) and 3 employees (0.4%) were diagnosed with SARS-CoV-2 infection via qPCR test. Phylogenetic analyses revealed that a super-spreader event among undergraduates in congregate housing accounted for at least 48% of cases among study participants but did not spread beyond campus. Test positivity was higher among participants who self-reported symptoms (incidence rate ratio (IRR) 12.7; 95% CI 7.4 to 21.8) or had household exposures (IRR 10.3; 95% CI 4.8 to 22.0) that triggered notifications to test. Most (91%) participants with newly identified antibodies at endline had been diagnosed with incident infection via qPCR test during the study. CONCLUSIONS: Our findings suggest that integrated monitoring systems can successfully identify and link at-risk students to SARS-CoV-2 testing. As the study took place before the evolution of highly transmissible variants and widespread availability of vaccines and rapid antigen tests, further research is necessary to adapt and evaluate similar systems in the present context.

RESUMO

Background: Pharmacies are a promising setting through which to expand access to human immunodeficiency virus (HIV) prevention, including pre-exposure and post-exposure prophylaxis (PrEP and PEP, respectively). We aimed to evaluate and inform the implementation of California's Senate Bill 159 (2019), allowing pharmacists to independently prescribe PrEP and PEP. Methods: From October through December 2022, we conducted a cross-sectional study of 919 California pharmacists and pharmacy students, primarily recruited via the email listservs of professional organizations. Participants completed an online survey assessing the implementation of pharmacist-initiated PrEP/PEP, including knowledge, attitudes, practices, perceived barriers, and implementation preferences elicited through a discrete choice experiment. Results: Among 919 participants (84% practicing pharmacists, 43% in community pharmacies), 11% and 13% reported that pharmacists at their pharmacy initiate PrEP and PEP, respectively. Most believed that pharmacist-initiated PrEP/PEP is important (96%) and were willing to provide PrEP (81%); fewer (27%) had PrEP/PEP training. Common implementation barriers were lack of staff/time and payment for pharmacist services. Participants preferred PrEP implementation models with in-pharmacy rapid oral HIV testing and pharmacists specifically hired to provide PrEP services. Conclusions: Despite pharmacists' supportive attitudes, Senate Bill 159 implementation in California pharmacies remains limited, in part due to policy-level and organizational-level barriers. Ensuring PrEP/PEP-related payment for services and sufficient workforce capacity is key to leveraging pharmacists' role in HIV prevention.

RESUMO

Background: Economic incentives can improve clinical outcomes among in-care people living with HIV (PLHIV), but evidence is limited for their effectiveness among out-of-care PLHIV or those at-risk of disengagement. We propose a type 1 hybrid effectiveness-implementation study to advance global knowledge about the use of economic incentives to strengthen the continuity of HIV care and accelerate global goals for HIV epidemic control. Methods: The Rudi Kundini, Pamoja Kundini study will evaluate two implementation models of an economic incentive strategy for supporting two groups of PLHIV in Tanzania. Phase 1 of the study consists of a two-arm, cluster randomized trial across 32 health facilities to assess the effectiveness of a home visit plus one-time economic incentive on the proportion of out-of-care PLHIV with viral load suppression (<1000 copies/ml) 6 months after enrollment (n = 640). Phase 2 is an individual 1:1 randomized controlled trial designed to determine the effectiveness of a short-term counseling and economic incentive program offered to in-care PLHIV who are predicted through machine learning to be at-risk of disengaging from care on the outcome of viral load suppression at 12 months (n = 692). The program includes up to three incentives conditional upon visit attendance coupled with adapted counselling sessions for this population of PLHIV. Consistent with a hybrid effectiveness-implementation study design, phase 3 is a mixed methods evaluation to explore barriers and facilitators to strategy implementation in phases 1 and 2. Results will be used to guide optimization and scale-up of the incentive strategies, if effective, to the larger population of Tanzanian PLHIV who struggle with continuity of HIV care. Discussion: Innovative strategies that recognize the dynamic process of lifelong retention in HIV care are urgently needed. Strategies such as conditional economic incentives are a simple and effective method for improving many health outcomes, including those on the HIV continuum. If coupled with other supportive services such as home visits (phase 1) or with tailored counselling (phase 2), economic incentives have the potential to strengthen engagement among the subpopulation of PLHIV who struggle with retention in care and could help to close the gap towards reaching global '95-95-95' goals for ending the AIDS epidemic.Phase 1: Clinicaltrials.gov, NCT05248100, registered 2/21/2022 https://clinicaltrials.gov/ct2/show/NCT05248100Phase 2: Clinicaltrials.gov, NCT05373095, registered 5/13/2022 https://clinicaltrials.gov/ct2/show/NCT05373095.

RESUMO

BACKGROUND: Optimizing retention in human immunodeficiency virus (HIV) treatment may require sequential behavioral interventions based on patients' response. METHODS: In a sequential multiple assignment randomized trial in Kenya, we randomly assigned adults initiating HIV treatment to standard of care (SOC), Short Message Service (SMS) messages, or conditional cash transfers (CCT). Those with retention lapse (missed a clinic visit by ≥14 days) were randomly assigned again to standard-of-care outreach (SOC-Outreach), SMS+CCT, or peer navigation. Those randomly assigned to SMS or CCT who did not lapse after 1 year were randomly assigned again to either stop or continue the initial intervention. Primary outcomes were retention in care without an initial lapse, return to the clinic among those who lapsed, and time in care; secondary outcomes included adjudicated viral suppression. Average treatment effect (ATE) was calculated using targeted maximum likelihood estimation with adjustment for baseline characteristics at randomization and certain time-varying characteristics at rerandomization. RESULTS: Among 1809 participants, 79.7% of those randomly assigned to CCT (n=523/656), 71.7% to SMS (n=393/548), and 70.7% to SOC (n=428/605) were retained in care in the first year (ATE: 9.9%; 95% confidence interval [CI]: 5.4%, 14.4% and ATE: 4.2%; 95% CI: -0.7%, 9.2% for CCT and SMS compared with SOC, respectively). Among 312 participants with an initial lapse who were randomly assigned again, 69.1% who were randomly assigned to a navigator (n=76/110) returned, 69.5% randomly assigned to CCT+SMS (n=73/105) returned, and 55.7% randomly assigned to SOC-Outreach (n=54/97) returned (ATE: 14.1%; 95% CI: 0.6%, 27.6% and ATE: 11.4%; 95% CI: -2.2%, 24.9% for navigator and CCT+SMS compared with SOC-Outreach, respectively). Among participants without lapse on SMS, continuing SMS did not affect retention (n=122/180; 67.8% retained) versus stopping (n=151/209; 72.2% retained; ATE: -4.4%; 95% CI: -16.6%, 7.9%). Among participants without lapse on CCT, those continuing CCT had higher retention (n=192/230; 83.5% retained) than those stopping (n=173/287; 60.3% retained; ATE: 28.6%; 95% CI: 19.9%, 37.3%). Among 15 sequenced strategies, initial CCT, escalated to navigator if lapse occurred and continued if no lapse occurred, increased time in care (ATE: 7.2%, 95% CI: 3.7%, 10.7%) and viral suppression (ATE: 8.2%, 95% CI: 2.2%, 14.2%), the most compared with SOC throughout. Initial SMS escalated to navigator if lapse occurred, and otherwise continued, showed similar effect sizes compared with SOC throughout. CONCLUSIONS: Active interventions to prevent retention lapses followed by navigation for those who lapse and maintenance of initial intervention for those without lapse resulted in best overall retention and viral suppression among the strategies studied. Among those who remained in care, discontinuation of CCT, but not SMS, compromised retention and suppression.
