RESUMEN

BACKGROUND: Sleep problems are reported for up to 80% of autistic individuals. We examined whether parsimonious sets of items derived from the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) and the Brief Infant Sleep Questionnaire (BISQ) are superior to the standard M-CHAT-R in predicting subsequent autism spectrum disorder (ASD) diagnoses. METHODS: Participants from 11 Environmental influences on Child Health Outcomes (ECHO) cohorts were included. We performed logistic LASSO regression models with 10-fold cross-validation to identify whether a combination of items derived from the M-CHAT-R and BISQ are superior to the standard M-CHAT-R in predicting ASD diagnoses. RESULTS: The final sample comprised 1552 children. The standard M-CHAT-R had a sensitivity of 44% (95% CI: 34, 55), specificity of 92% (95% CI: 91, 94), and AUROC of 0.726 (95% CI: 0.663, 0.790). A higher proportion of children with ASD had difficulty falling asleep or resisted bedtime during infancy/toddlerhood. However, LASSO models revealed parental reports of sleep problems did not improve the accuracy of the M-CHAT-R in predicting ASD diagnosis. CONCLUSION: While children with ASD had higher rates of sleep problems during infancy/toddlerhood, there was no improvement in ASD developmental screening through the incorporation of parent-report sleep metrics. IMPACT: Parental-reported sleep problems are common in autism spectrum disorder (ASD). We investigated whether the inclusion of parental-reports of infant/toddler sleep patterns enhanced the effectiveness of developmental screening for autism. We reported higher rates of difficulty falling asleep and resisting bedtime during infancy and toddlerhood among children later diagnosed with ASD; however, we did not find an improvement in ASD developmental screening through the incorporation of parent-report sleep metrics. In our sample, the standard M-CHAT-R had a sensitivity of 39% among children of mothers with government insurance compared with a sensitivity of 53% among children of mothers with employer-based insurance.

RESUMEN

Intersecting forms of stigma including both HIV and sex work stigma have been known to impede HIV prevention and optimal treatment outcomes among FSW. Recent research has indicated that intersectional stigma can be resisted at the community and individual level. We assessed pathways between HIV stigma, sex work stigma, social cohesion and viral suppression among a cohort of 210 FSW living with HIV in the Dominican Republic. Through Poisson regression we explored the relationship between HIV outcomes and internalized, anticipated and enacted HIV and sex work stigma, and resisted sex work stigma. We employed structural equation modeling to explore the direct effect of various forms of stigma on HIV outcomes, and the mediating effects of multi-level stigma resistance including social cohesion at the community level and occupational dignity at the individual level. 76.2% of FSW were virally suppressed and 28.1% had stopped ART at least once in the last 6 months. ART interruption had a significant negative direct effect on viral suppression (OR = 0.26, p < 0.001, 95% CI: 0.13-0.51). Social cohesion had a significant positive direct effect on viral suppression (OR = 2.07, p = 0.046, 95% CI: 1.01-4.25). Anticipated HIV stigma had a significant negative effect on viral suppression (OR = 0.34, p = 0.055, 95% CI: 0.11-1.02). This effect was mediated by the interaction between cohesion and dignity which rendered the impact of HIV stigma on viral suppression not significant. Findings demonstrate that while HIV stigma has a negative impact on viral suppression among FSW, it can be resisted through individual and collective means. Results reinforce the importance of community-driven, multi-level interventions.

RESUMEN

Background: Adult studies have demonstrated that polysubstance use increases HIV acquisition risk through increased sexual behaviors, however, few studies have examined polysubstance in young Black and Latinx sexual minority men (SMM) and transgender women (TW). Methods: We used cross-sectional data from 466 young Black and Latinx SMM and TW living in four high HIV-burden US cities enrolled in the PUSH Study, a status-neutral randomized control trial to increase HIV prevention and treatment adherence. We examined data for patterns of polysubstance use comparing age differences of use and explored associations between substance use and sexual partnership factors - inconsistent condom use, pressure to have condomless anal sex, and older partner, using bivariate and multivariate analyses. Results: Most participants described prior substance use with alcohol and cannabis being most common (76% each) and 23% described other illicit drug use, including stimulants, cocaine, hallucinogens, sedatives, opioids, and inhalants. Polysubstance use was common with nearly half (47%) of participants reporting alcohol and cannabis use, 20% reporting alcohol, cannabis, and one other illicit drug use, and 19% reporting alcohol or cannabis use plus one other illicit drug use. Polysubstance use was associated with greater adjusted odds of pressure to have condomless anal sex, older partner (>5 years older), and inconsistent condom use. Conclusions: Associations of polysubstance use with sexual practices and sexual partnerships that are known predictors of HIV acquisition or transmission among Black and Latinx SMM and TW underscore the need for combination interventions that include substance use treatment alongside antiretroviral-based and partner-based HIV prevention and treatment interventions.Trial Registration: ClinicalTrials.gov Identifier: NCT03194477.

RESUMEN

BACKGROUND: Female sex workers ( FSWs) are vulnerable to a number of health issues, but often delay seeking health care due to structural barriers. Multiservice drop-in centers have been shown to increase FSW access to health services globally, but their impact on FSW in the United States is lacking. This study seeks to evaluate the effect of a community-level empowerment intervention (the multiservice drop-in SPARC center) on cumulative sexually transmitted infections (STIs) among FSW in a city in the United States. METHODS: Between September 2017 and January 2019, 385 FSWs were recruited in Baltimore. Participants from areas served by SPARC were recruited to the intervention; other areas of Baltimore were the control. Follow-up occurred at 6, 12, and 18 months. The primary outcome is cumulative STI (ie, positive gonorrhea or chlamydia test at any follow-up). We tested effect modification by condomless sex with paying clients reported at baseline. Logistic regressions with propensity score weighting were used to estimate intervention effect, accounting for loss to follow-up, with bootstrap confidence intervals. RESULTS: Participants completed 713 follow-up study visits (73%, 70%, 64% retention at 6, 12, and 18 months, respectively). Baseline STI prevalence was 28% and cumulative STI prevalence across follow-ups was 26%; these both did not differ between control and intervention communities in bivariate analyses. After adjusting for covariates, FSW in the intervention had a borderline-significant decrease in odds of cumulative STI compared with control (odds ratio, 0.61, P = 0.09 ) . There was evidence of effect modification by baseline condomless sex, such that FSW in the intervention who reported condomless sex had lower odds of cumulative STI compared with FSW in the control community who also reported baseline condomless sex (odds ratio, 0.29; P = 0.04). CONCLUSIONS: Results demonstrate the value of a low-barrier, multiservice model on reducing STIs among the highest-risk FSW.Clinical Trial Number: NCT04413591.

RESUMEN

Female sex workers (FSW) have worse HIV outcomes in part due to lower anti-retroviral therapy (ART) adherence. Substance use and depression are important barriers to ART adherence, yet few studies have assessed these relationships among FSW in longitudinal studies. Cross-Lagged Panel Models and autoregressive mediation analyses assessed substance use (illicit drug use and alcohol use disorders) in relation to ART non-adherence and the mediation role of depressive symptoms among 240 FSW living with HIV in the Dominican Republic. In annual visits (T1, T2, T3), the majority (70%, 66%, and 53%) reported at-risk drinking and 15%, 13% and 9% used illicit drug during the past 6 months. Most FSW (70%, 62% and 46%) had mild-to-severe depression. Illicit drug use predicted later ART non-adherence. This relationship was not mediated via depressive symptoms. Integrated substance use and HIV care interventions are needed to promote ART adherence and viral suppression among FSW.


RESUMEN: Las trabajadoras sexuales (TRSX) tienen peores resultados de VIH debido en parte a la menor adherencia a la terapia antirretroviral (TAR). El uso de sustancias y la depresión son barreras importantes para la adherencia; sin embargo, pocos estudios longitudinales han evaluado estas relaciones entre las TRSX. Utilizamos modelos de panel y análisis de mediación para evaluar el uso de sustancias en relación a la falta de adherencia al TAR y el papel de mediación de los síntomas depresivos entre 240 TRSX con VIH en la República Dominicana. En visitas anuales (T1, T2, T3), la mayoría (70%, 66%, and 53%) reportó consumo riesgoso de alcohol y 15%, 13% y 9% consumieron alguna droga ilícita durante los últimos 6 meses. La mayoría (70%, 62% y 46%) tenían depresión leve a grave. El uso de drogas ilícitas predijo la falta de adherencia al TAR. Esta relación no fue mediada por síntomas depresivos. Se necesitan intervenciones integradas de atención del VIH y el uso de sustancias para promover la adherencia al TAR y la supresión viral entre TRSX.

RESUMEN

This study assessed the relationship between the quality of HIV care and treatment literacy on antiretroviral therapy (ART) adherence and viral suppression among female sex workers (FSWs) living with HIV (n = 211) in Santo Domingo, Dominican Republic. Multivariable logistic regression results indicate better patient-provider communication (AOR 1.04; 95% CI 1.01-1.07) and respectful treatment (AOR 2.17; 95% CI 1.09-4.32) increase the odds of viral suppression, while higher costs reduce both the odds of ART adherence (AOR 0.57, 95% CI 0.34- 0.95) and being virally suppressed (AOR 0.59, 95% CI 0.41-0.85). Greater treatment literacy was associated with an increased odds of ART adherence (AOR 4.15 for understanding of viral load; 95% CI 1.50-11.52) and viral suppression (AOR 2.75 for understanding of CD4 count; 95% CI 1.31-5.80). Findings support investments in treatment education, effective and respectful patient-provider communication, dignified care, and cost-support for associated HIV care costs to facilitate FSWs' pathway towards viral suppression.


RESUMEN: Este estudio evaluó la relación entre la calidad de la atención para el VIH y la alfabetización relacionada al tratamiento sobre la adherencia a la terapia antirretroviral (TAR) y la supresión viral entre las trabajadoras sexuales (TRSX) que viven con el VIH (n = 211) en Santo Domingo, República Dominicana. Los resultados de la regresión logística multivariable indican una mejor comunicación entre el paciente y el proveedor (RMa: 1.04; IC del 95%: 1.01­1.07) y un tratamiento respetuoso (RMa: 2.17; IC del 95%: 1.09­4.32) aumenta la probabilidad de supresión viral, mientras que los costos elevados reducen tanto las probabilidades de adherencia al TAR (RMa: 0.57; IC del 95%: 0.34­0.95) como la supresión viral (RMa: 0.59, IC del 95%: 0.41­0.85). Una mayor alfabetización relacionada al tratamiento se asoció con una mayor probabilidad de adherencia al TAR (RMa: 4.15 para la comprensión de la carga viral; IC del 95%: 1.50­11.52) y la supresión viral (RMa: 2.75 para la comprensión del conteo de CD4; IC del 95%: 1.31­5.80). Los hallazgos respaldan inversiones en educación sobre el tratamiento, la comunicación efectiva y respetuosa entre el paciente y el proveedor, la atención digna y el apoyo económico para los costos asociados con la atención del VIH para facilitar el camino de las TRSX hacia la supresión viral.

RESUMEN

Pre-exposure prophylaxis (PrEP) rollout efforts thus far have inadequately reached young people from underrepresented backgrounds. This study explores PrEP engagement among young Black and Latinx men who have sex with men, transgender women, and gender diverse individuals in three U.S. cities using an adapted PrEP continuum measure. We analyze data from the recruitment phase of an ongoing PrEP engagement intervention (n = 319) using partial proportional odds logistic regression. Participants reported high willingness and intention to use PrEP, yet most (82%) were not currently taking PrEP. Being insured (aOR = 2.95, 95%-CI = 1.60-5.49), having one or more PrEP users in one's sexual network (aOR = 4.19, 95%-CI = 2.61-6.79), and higher individual HIV risk scores (aOR = 1.62, 95%-CI = 1.34-1.97) were each associated with being further along the PrEP continuum. Strategies are needed to address barriers to healthcare access and leverage connections within social and sexual networks in order to bolster PrEP engagement among marginalized young people from diverse backgrounds.


RESUMEN: Los esfuerzos de dar a conocer la profilaxis prexposición (PrEP) hasta el momento han llegado de forma inadecuada a los jóvenes de entornos desfavorecidos. Este estudio explora en tres ciudades de los EE. UU. el compromiso con la PrEP entre los jóvenes de raza negra y latino quienes son minorías sexuales o de género, utilizando una medida de seguimiento de la PrEP adaptada. Analizamos los datos de la fase de reclutamiento de una participación en la PrEP en curso (n = 319) utilizando una regresión logística parcial de probabilidades proporcionales. Los participantes manifestaron una alta disposición e intención de utilizar la PrEP, aunque la mayoría (82%) no tomaba actualmente la PrEP. Estar asegurado (aOR = 2,95, 95%-CI = 1,60­5,49), tener uno o más usuarios de la PrEP en su red sexual (aOR = 4,19, 95%-CI = 2,61­6,79), y mayores puntuaciones individuales de riesgo de VIH (aOR = 1,62, 95%-CI = 1,34­1,97) se asociaron con el hecho de llevar un seguimiento estrecho con la PrEP. Se necesitan estrategias para abordar las barreras de acceso a la atención médica y aprovechar las conexiones entre las redes sociales y las de carácter sexual, con el fin de reforzar el compromiso con la PrEP entre los jóvenes marginados de diversas procedencias.

RESUMEN

Among women who exchange sex (WES), social cohesion is associated with multi-level HIV-risk reduction factors, and client condom coercion (CCC) is associated with increased HIV-risk. Sexual minority WES (SM-WES) face exacerbated HIV-risk, yet relevant research is scant. We examined the role of sexual orientation in the relationship between social cohesion and CCC among cisgender WES (n = 384) in Baltimore, Maryland using stratified logistic regression, controlling for potential confounders. Forty-five percent of WES experienced CCC. SM-WES reported significantly higher social cohesion than heterosexual WES. The relationship between social cohesion and CCC differed by sexual orientation. Among SM-WES, higher social cohesion was independently associated with decreased odds of experiencing CCC, controlling for food insecurity, crack use, police harassment, and method of finding clients. Among heterosexual WES, no significant association was found. Ongoing research and practice with WES should (1) collect sexual orientation data to allow for deeper understanding and tailored interventions, (2) leverage and nurture social cohesion and (3) tailor interventions to populations with attention to sexual orientation.


RESUMEN: Among women who exchange sex (WES), social cohesion is associated with multi-level HIV-risk reduction factors, and client condom coercion (CCC) is associated with increased HIV-riskEntre las mujeres que intercambian sexo (WES), la cohesión social atenúa el riesgo de VIH, y la coerción del uso del condón por parte de clientes (CCC) amplifica el riesgo de VIH. Las WES de minorías sexuales (SM-WES) experiencian un riesgo elevado de VIH, pero las investigaciónes relevantes son pocas. En este papel, examinamos la contribución de la orientación sexual en modificando la relación entre la cohesión social y la CCC entre WES cisgénero (n = 384) en Baltimore, Maryland, utilizando regresión logística estratificada, ajustando por posibles factores de confusión. Cuarenta y cinco por ciento de WES reportaron experiencias de CCC. SM-WES exhibieron cohesión social significativamente más alta que las WES heterosexuales. La relación entre la cohesión social y CCC fue moderada por la orientación sexual. Entre SM-WES, la cohesión social se asoció independientemente con menores probabilidades de reportar experiencias de CCC, ajustando por la inseguridad alimentaria, el uso de crack, el acoso policial y el método de encontrar a clientes. Entre las WES heterosexuales, la misma asociación no fue significativa. La investigación y la práctica con WES deben 1) recopilar datos de orientación sexual para permitir una comprensión más profunda e intervenciones personalizadas, 2) aprovechar y fomentar la cohesión social y 3) adaptar las intervenciones a estas poblaciones con atención a la orientación sexual.

RESUMEN

OBJECTIVES: Though highly vulnerable to HIV and STIs, transgender female sex workers (TFSWs) are understudied in the US HIV and STI response. This study examined the correlates of laboratory-confirmed STIs among a cohort of 62 TFSWs followed over the course of 1 year and explored associations between specimen site and self-reported engagement in insertive and receptive anal intercourse. METHODS: Participants completed an interviewer-administered computer-assisted personal interview at baseline, 3-, 6-, 9- and 12-month visits where self-administered anal swabs and urine samples for gonorrhea, chlamydia and trichomoniasis were also collected. HIV testing was conducted at baseline, 6-month and 12-month visits. RESULTS: Baseline HIV prevalence was 40.3% with no HIV seroconversions over follow-up. Baseline prevalence of gonorrhea, chlamydia and trichomoniasis was 9.7%, 17.7% and 14.5%, respectively. In the multivariable regression modelling, recent arrest was significantly associated with testing positive for any STI (adjusted risk ratio (RR) 1.77; 95% CI: 1.10 to 2.84). Insertive anal sex with clients was associated with increased risk of testing positive for an STI via urine specimen (RR 3.48; 95% CI: 1.14 to 10.62), while receptive anal sex was not significantly associated with specimen site. CONCLUSION: Our findings confirm a high prevalence of STIs among TFSWs and highlight the importance of addressing structural drivers such as criminal justice involvement as well as the need to ensure screening for STIs at all anatomical sites regardless of self-reported sites of potential exposure. More research is needed to better understand HIV and STI vulnerabilities and appropriate interventions for TFSWs in the USA.

RESUMEN

BACKGROUND: Female sex workers (FSWs) have elevated rates of sexually transmitted infections (STIs) including HIV, yet few studies in the United States have characterized the STI burden in this population. METHODS: Data were derived from the EMERALD study, a structural community-based intervention with FSWs in Baltimore, MD. Participants (n = 385) were recruited through targeted sampling on a mobile van. Prevalent positive chlamydia or gonorrhea infections were determined by biological samples. Multivariable logistic regressions modeled correlates of confirmed positive STI (gonorrhea or chlamydia). RESULTS: Confirmed STI positive prevalence was 28%, 15% chlamydia and 18% gonorrhea. Approximately two-thirds of the sample (64%) was younger than 40 years, one-third (36%) were Black, and 10% entered sex work in the past year. The sample was characterized by high levels of structural vulnerabilities (e.g., housing instability and food insecurity) and illicit substance use. Female sex workers were more likely to have a positive STI if they had financial dependent(s) (P = 0.04), experienced food insecurity at least weekly (P = 0.01), entered sex work in the past year (P = 0.002), and had 6 or more clients in the past week (P = 0.01). Female sex workers were less likely to have a positive STI test result if they were 40 years or older compared with FSW 18 to 29 years old (P = 0.02), and marginally (P = 0.08) less likely with high (vs. low) social cohesion. CONCLUSIONS: More than a quarter of FSWs had confirmed chlamydia or gonorrhea. In addition to STI risks at the individual level, STIs are driven by structural vulnerabilities. Results point to a number of salient factors to be targeted in STI prevention among FSWs.

RESUMEN

There is growing evidence for the key role of social determinants of health (SDOH) in understanding morbidity and mortality outcomes globally. Factors such as stigma, racism, poverty or access to health and social services represent complex constructs that affect population health via intricate relationships to individual characteristics, behaviors and disease prevention and treatment outcomes. Modeling the role of SDOH is both critically important and inherently complex. Here we describe different modeling approaches and their use in assessing the impact of SDOH on HIV/AIDS. The discussion is thematically divided into mechanistic models and statistical models, while recognizing the overlap between them. To illustrate mechanistic approaches, we use examples of compartmental models and agent-based models; to illustrate statistical approaches, we use regression and statistical causal models. We describe model structure, data sources required, and the scope of possible inferences, highlighting similarities and differences in formulation, implementation, and interpretation of different modeling approaches. We also indicate further needed research on representing and quantifying the effect of SDOH in the context of models for HIV and other health outcomes in recognition of the critical role of SDOH in achieving the goal of ending the HIV epidemic and improving overall population health.

RESUMEN

Female sex workers' (FSWs) risk for HIV/STIs is influenced by their work environments. While previous research has characterized vulnerability in a single workplace, many FSWs solicit clients from multiple settings. Using latent class analysis (LCA), we examined client solicitation patterns and associated HIV/STI-related behaviors (consistent condom use with clients, asking clients about HIV/STIs, and past 6-month HIV/STI testing) among 385 FSWs in Baltimore, Maryland. The LCA yielded a three-class solution: predominantly street (61.2%), mixed street/venue (23.7%), and multisource (street, venue, and online) (15.1%). Consistent condom use differed significantly (p < 0.01) by class, with the mixed street/venue having the lowest (40.6%) rate and the multisource having the highest (70.6%). Classes differed on HIV/STI testing (p < 0.01), with the predominantly street class having the lowest testing rate (56.2%) and multisource with the highest (85.7%). These findings underscore the importance of considering how solicitation patterns are linked to HIV/STI susceptibility of FSWs and adapting interventions accordingly.

RESUMEN

While HIV stigma has received significant attention, limited work has been conducted on the measurement of intersecting stigmas. We developed the Experiences of Sex Work Stigma (ESWS) scale in the Dominican Republic (DR) and Tanzania. We conducted in-depth interviews with 20 female sex workers (FSW) per country to identify scale domains followed by cognitive debriefing interviews to assess content validity. Items were administered in a survey to FSW in DR (n = 211) and Tanzania (n = 205). Factor analysis established four sex work stigma domains including: shame (internalized), dignity (resisted), silence (anticipated) and treatment (enacted). Reliability across domains ranged from 0.81 to 0.93. Using item response theory (IRT) we created context-specific domain scores accounting for differential item functioning between countries. ESWS domains were associated with internalized HIV stigma, depression, anxiety, sexual partner violence and social cohesion across contexts. The ESWS is the first reliable and valid scale to assess multiple domains of sex work stigma and can be used to examine the effects of this form of intersectional stigma on HIV-related outcomes across settings.

RESUMEN

We examined the relationship between mindfulness, mental health and HIV outcomes among female sex workers (FSW) from the Dominican Republic (DR) (n = 201) and Tanzania (n = 208) using cross-sectional survey and biologic data. We employed stratified multivariate linear and logistic regression. Depression was associated with lower odds of ART adherence in the DR (AOR 0.25, 95% CI: 0.08-0.78) and of viral suppression in Tanzania (AOR 0.49, 95% CI: 0.24-0.97). In both countries, mindfulness was associated with lower odds of moderate to severe depression (AOR 0.82, 95% CI: 0.76-0.88 for the DR; AOR 0.85, 95% CI: 0.77-0.95 for Tanzania). In the DR, mindfulness was associated with lower odds of anxiety (AOR 0.83, 95% CI: 0.77-0.89), lower HIV stigma (ß = - 0.28 per unit change, 95% CI: - 0.37 to - 0.19) and greater odds of viral suppression (AOR 1.09, 95% CI: 1.02-1.15). Findings demonstrate the potential of tailored mindfulness interventions to improve mental health and HIV outcomes among FSW.


RESUMEN: Examinamos la relación entre la atención plena, la salud mental y los resultados del VIH entre las trabajadoras sexuales (TRSX) de la República Dominicana (RD) (n = 201) y Tanzania (n = 208) utilizando una encuesta transversal y datos biológicos. Empleamos regresión lineal multivariada estratificada y regresión logística. La depresión se asoció con menores probabilidades de adherencia al terapia antiretroviral (TAR) en la República Dominicana (AOR 0.25, IC del 95%: 0.08­0.78) y de supresión viral en Tanzania (AOR 0.49, IC del 95%: 0.24­0.97). En ambos países, la atención plena se asoció con menores probabilidades de depresión moderada a grave (AOR 0.82, IC del 95%: 0.76­0.88 para la República Dominicana; AOR 0.85, IC del 95%: 0.77­0.95 para Tanzania). En la República Dominicana, la atención plena se asoció con menores probabilidades de ansiedad (AOR 0.83, IC del 95%: 0.77­0.89), menor estigma del VIH (ß = − 0.28 por unidad de cambio, IC del 95%: − 0.37 to − 0.19) y mayores probabilidades de supresión viral (AOR 1.09, 95% CI: 1.02­1.15). Los hallazgos demuestran el potencial de las intervenciones de atención plena para mejorar la salud mental y los resultados del VIH entre las TRSX.

RESUMEN

BACKGROUND: Female sex workers in sub-Saharan Africa face high unmet need for family planning and higher risk for unintended pregnancy. Community empowerment HIV prevention approaches have the potential to increase family planning uptake and present an opportunity to integrate HIV, reproductive health, and contraception. This article describes family planning use and pregnancy among female sex workers in Iringa, Tanzania and evaluates whether engagement in a community empowerment HIV prevention program is associated with contraceptive use. METHODS: This study consists of secondary analysis from a two-community randomized controlled trial following a longitudinal cohort over 18 months. We implemented a year-long community empowerment intervention consisting of 1) a community-led drop-in-center; 2) venue-based peer education, condom distribution, and HIV testing; 3) peer service navigation; 4) sensitivity trainings for providers and police; and 5) text messages to promote engagement. Additionally, monthly seminars were held at the drop-in-center, one of which focused on family planning. Modified Poisson regression models were used to estimate the association between program exposure and family planning use in the intervention arm. (Trials Registration NCT02281578, Nov 2, 2014.) RESULTS: Among the 339 participants with follow-up data on family planning, 60% reported current family planning use; 6% reported dual use of modern contraception and condoms; over 90% had living children; and 85% sought antenatal care at their most recent pregnancy. Among the 185 participants in the intervention arm, the adjusted relative risk (aRR) of family planning use among female sex workers who reported ever attending the Shikamana drop-in-center and among female sex workers who reported attending a family planning-related workshop was respectively 26% (aRR 1.26 [95% Confidence Interval (CI): 1.02-1.56]) and 36% (aRR 1.36 [95%CI: 1.13-1.64) higher than among those who had not attended. CONCLUSION: There is a clear need for family planning among this population. General program exposure and exposure to a family planning workshop were associated with higher family planning use, which suggests that community empowerment models have potential to increase family planning uptake for this vulnerable group.

RESUMEN

BACKGROUND: The role of business employees and community members in the HIV risk environment of female sex workers (FSW) is underexplored, despite sex work often located in commercial and residential urban areas. We explored the effect of negative interactions between business employees and community members on inconsistent condom use with clients of female sex workers. METHODS: This study uses baseline data from the EMERALD study, a community empowerment intervention with FSW. We recruited a sample of 361 FSW in Baltimore, Maryland using targeted sampling techniques in ten zones characterized by high rates of sex work, located throughout the city. Participants were recruited between September 2017 and January 2019 and completed a survey, HIV rapid testing, and self-administered gonorrhea and chlamydia testing. The outcome, inconsistent condom use, was defined as not reporting "always" using condoms with paying clients. Poisson regressions with robust variance were used to model the effect of business employee and/or community member interactions on inconsistent condom use. RESULTS: Over half (54%) the sample was between 18 and 40 years old, 44% Black or another race, and experienced a range of structural vulnerabilities such as housing instability and food insecurity. Forty-four percent of the sample reported inconsistent condom use with clients. FSW reported being reported to the police weekly or daily for selling drugs (14% by employees, 17% by community), for selling sex (19% by employees, 21% by community), and experiencing weekly or daily verbal or physical threats (18% by employees, 24% by community). In multivariable models, being reported to the police for selling sex weekly or daily by community members (vs. never, aRR = 1.42, 95% CI = 1.08, 1.86) and business owners (vs. never, aRR = 1.36, 95% CI = 1.05, 1.76) increased risk of inconsistent condom use, as did monthly verbal or physical threats by community members (vs. never, aRR = 1.43, 95% CI = 1.08, 1.91). CONCLUSIONS: Results show that both actors play important roles in FSWs' HIV risk environment. Businesses and community members are important targets for holistic HIV prevention interventions among FSW in communities where they coexist in close proximity.

RESUMEN

BACKGROUND: Long-acting injectable antiretroviral therapy (LA ART) has been shown to be non-inferior to daily oral ART, with high patient satisfaction and preference to oral standard of care in research to date, and has recently been approved for use in the United States and Europe. This study examined the perspectives of health care providers participating in LA ART clinical trials on potential barriers and solutions to LA ART roll-out into real world settings. METHODS: This analysis draws on two data sources: (1) open-ended questions embedded in a structured online survey of 329 health care providers participating in the ATLAS-2 M trial across 13 countries; and (2) in-depth interviews with 14 providers participating in FLAIR/ ATLAS/ATLAS-2 M trials in the United States and Spain. Both assessments explored provider views and clinic dynamics related to the introduction of LA ART and were analyzed using thematic content analysis. The Consolidated Framework for Implementation Research (CFIR) was drawn on as the conceptual framework underpinning development of a model depicting study findings. RESULTS: Barriers and proposed solutions to LA ART implementation were identified at the individual, clinic and health system levels. Provider perceptions of patient level barriers included challenges with adhering to frequent injection appointments and injection tolerability. Proposed solutions included patient education, having designated staff for clinic visit retention, and clinic flexibility with appointment scheduling. The main provider concern was identifying appropriate candidates for LA ART; proposed solutions focused on patient provider communication and decision making. Clinic level barriers included the need for additional skilled individuals to administer injections, shifts in workflow as demand increases and the logistics of cold-chain storage. Proposed solutions included staff hiring and training, strategic planning around workflow and logistics, and the possibility of offering injections in other settings, including the home. Health system level barriers included cost and approvals from national regulatory bodies. Potential solutions included governments subsidizing treatment, ensuring cost is competitive with oral ART, and offering co-pay assistance. CONCLUSIONS: Results suggest the importance of multi-level support systems to optimize patient-provider communication and treatment decision-making; clinic staffing, workflow, logistics protocols and infrastructure; and cost-related factors within a given health system.

RESUMEN

PURPOSE OF REVIEW: This review describes social determinants of HIV in two geographic and epidemic settings, the Dominican Republic (DR) and Tanzania, among female sex workers (FSW), their influence on HIV outcomes including 90-90-90 goals, and the development and impact of tailored, context driven, community empowerment-based responses in each setting. RECENT FINDINGS: Our review documents the significance of social determinants of HIV including sex work-related stigma, discrimination, and violence and the impact of community empowerment-based approaches on HIV incidence in Tanzania and other HIV prevention, treatment, and care outcomes, including care engagement and adherence, in the DR and Tanzania. Community empowerment approaches where FSW drive the response to HIV and strategically engage partners to target socio-structural and environmental factors can have a demonstrable impact on HIV prevention, treatment, and care outcomes. Such approaches can also support further gains towards reaching the 90-90-90 across geographies and types of epidemics.

RESUMEN

Female sex workers (FSWs) are disproportionately affected by HIV. Inconsistent condom use (ICU) represents the most proximal risk for acquisition and transmission. We evaluate associations of partner-specific factors including physical and sexual violence, coercion, and substance use with ICU with clients and regular non-paying partners, respectively, among FSWs. Baseline survey data from a prospective cohort of 250 street-based FSW in Baltimore, Maryland, USA included partner-level drug and alcohol use, violence, condom coercion and ICU, in addition to individual and structural exposures. Logistic regression analyses were stratified by partner type, followed by path analysis where indicated. Within client and regular non-paying partnerships, FSWs reported prevalent recent violence (34.8%, 16%, respectively), condom coercion (42.4%, 9.9%, respectively) and ICU (39.2%, 44.4%, respectively). Recent physical or sexual violence enabled coercive condom negotiation (AORclient 8.22, 95% CI 4.30, 15.73; AORnonpayingpartner 3.01 95% CI 1.05, 8.63). ICU with clients was associated with client condom coercion (AOR 1.76, 95% CI 1.03, 3.02), and client intoxication during sex (AOR 2.25, 95% CI 1.13, 4.45). In path analysis of client-FSW partnerships, condom coercion fully mediated the influences of both sex worker intoxication and recent violence on ICU. ICU with non-paying partners was associated with FSW intoxication during sex (AOR 8.66, 95% CI 3.73, 20.10), and past-year police violence (AOR 2.92, 1.30, 6.57). Partner-level substance use and gendered power differentials influenced FSWs' ICU patterns differently by partner type. ICU with clients was rooted solely in partner factors, and coercive condom negotiation mediated the roles of violence and partner-level substance use on ICU. By contrast, ICU with non-paying partners was rooted in partner-level substance use and police violence as a structural determinant. Addressing HIV risk behavior for FSWs requires condom promotion efforts tailored to partner type that addresses power differentials.

RESUMEN

OBJECTIVE: Gender-based violence threatens women's health and safety. Female sex workers (FSWs) experience violence disproportionately, yet prospective data on violence predictors is lacking. In the first US-based prospective FSW cohort study, we examine incidence rates (IRs) and predictors of violence from distinct perpetrators: paying clients, non-paying intimate partners and police. METHODS: The parent cohort (Sex Workers and Police Promoting Health In Risky Environments) recruited street-based cisgender FSWs in urban Baltimore, MD (n=250) with 5 assessments at 3-month intervals through 12-month follow-up. Stratifying by violence perpetrator, we characterise violence at baseline, IR over the study period and time-varying predictors using Poisson models. RESULTS: The violence IR per person year was highest for client-perpetrated violence (0.78), followed by intimate partner violence (IPV; IR 0.39), and police violence (IR 0.25). Prevalence over the 12-month follow-up period among participants with complete visit data (n=103), was 42% for client violence, 22% for IPV and 16% for police violence. In adjusted analyses, risk factors for incident violence varied across perpetrators and included entry to sex work through force or coercion (adjusted IR ratio (aIRR)IPV 2.0; 95% CI 1.2 to 3.6), homelessness (aIRRIPV 2.0; 95% CI 1.3 to 2.9; aIRRpolice 2.7; 95% CI 1.3 to 5.8) and daily injection drug use (aIRRclient 1.9; 95% CI 1.2 to 3.0). Risk of incident client violence and IPV was elevated by past abuse from each respective perpetrator. Help-seeking following abuse was limited. CONCLUSIONS: FSWs face profound, enduring risk for violence from a range of perpetrators, likely enabled by criminalisation-related barriers to justice and perpetrator impunity. FSWs represent a priority population for access to justice, trauma-informed healthcare and violence-related support services. Structural vulnerabilities including homelessness and addiction represent actionable priorities for improving safety and health.
