RESUMEN

Male circumcision is a protective HIV prevention strategy. However, uncircumcised Zambian men are reluctant to undergo voluntary medical male circumcision (VMMC). Tailored interventions are necessary to stimulate the uptake of early infant male circumcision (EIMC) and VMMC in Zambia. This feasibility study presents the formative process of utilising the PRECEDE framework in the development of a family-centred EIMC/VMMC intervention, Like Father Like Son, and its application in an existing VMMC intervention, Spear & Shield. We found that fear of the pain associated with EIMC procedures, foreskin disposal, beliefs in children's autonomy and rights, and men's dominance in health decision-making were factors affecting EIMC uptake. Perceived benefits for infants included improved hygiene, protection from HIV infection, and faster recovery. Reinforcing factors included female partners and fathers' MC status. The availability and access to EIMC services and information, skill and experience of health workers, and engagement and belief in traditional circumcision practices were factors enabling EIMC uptake. These individual, interpersonal, and structural factors positively and negatively influencing EIMC uptake in the Zambian clinic context were integrated into the intervention for expecting parents. Feedback from community advisory boards suggested the process was effective in developing a culturally tailored and acceptable EIMC/VMMC promotion intervention.

RESUMEN

INTRODUCTION: This study used an unsupervised machine learning algorithm, sidClustering and random forests, to identify clusters of risk behaviors of Bacterial Vaginosis (BV), the most common cause of abnormal vaginal discharge linked to STI and HIV acquisition.  METHODS: Participants were 391 cisgender women in Miami, Florida, with a mean of 30.8 (SD = 7.81) years of age; 41.7% identified as Hispanic; 41.7% as Black and 44.8% as White. Participants completed measures of demographics, risk behaviors [sexual, medical, and reproductive history, substance use, and intravaginal practices (IVP)], and underwent collection of vaginal samples; 135 behavioral variables were analyzed. BV was diagnosed using Nugent criteria. RESULTS: We identified four clusters, and variables were ranked by importance in distinguishing clusters: Cluster 1: nulliparous women who engaged in IVPs to clean themselves and please sexual partners, and used substances frequently [n = 118 (30.2%)]; Cluster 2: primiparous women who engaged in IVPs using vaginal douches to clean themselves (n = 112 (28.6%)]; Cluster 3: primiparous women who did not use IVPs or substances [n = 87 (22.3%)]; and Cluster 4: nulliparous women who did not use IVPs but used substances [n = 74 (18.9%)]. Clusters were related to BV (p < 0.001). Cluster 2, the cluster of women who used vaginal douches as IVPs, had the highest prevalence of BV (52.7%). CONCLUSIONS: Machine learning methods may be particularly useful in identifying specific clusters of high-risk behaviors, in developing interventions intended to reduce BV and IVP, and ultimately in reducing the risk of HIV infection among women.

RESUMEN

Background: Many clinical and population-based research studies pivoted from in-person assessments to phone-based surveys due to the COVID-19 pandemic. The impact of these transitions on survey response remains understudied, especially for people living with HIV. Given that there are gender-specific trends in alcohol and substance use, it is particularly important to capture these data for women.Objective: Identify factors associated with responding to an alcohol and substance use phone survey administered during the COVID-19 pandemic in the Women's Interagency HIV Study, a multicenter US prospective cohort of women living with and without HIV.Methods: We used multivariable logistic regression to assess for associations of pre-pandemic (April-September 2019) sociodemographic factors, HIV status, housing status, depressive symptoms, alcohol use, and substance use with response to an early-pandemic (August-September 2020) phone survey.Results: Of 1,847 women who attended an in-person visit in 2019, 78% responded to a phone survey during the pandemic. The odds of responding were lower for women of Hispanic ethnicity (aOR 0.47 95% CI 0.33-0.66, ref=Black/African American) and those who reported substance use (aOR 0.63 95% CI 0.41-0.98). By contrast, the odds were higher for White women (aOR 1.64 95% CI 1.02-2.70, ref=Black/African American) and those with stable housing (aOR 1.74 95% CI 1.24-2.43).Conclusions: Pivoting from an in-person to phone-administered alcohol and substance use survey may lead to underrepresentation of key subpopulations of women who are often neglected in substance use and HIV research. As remote survey methods become more common, investigators need to ensure that the study population is representative of the target population.

RESUMEN

Human immunodeficiency virus-1 (HIV-1) clade C is the most prevalent form of HIV-1 comprising nearly 46% of global infections and is the dominant subtype in India. Despite its predominance, the impact of HIV-1 clade C infection on cognitive function has been understudied in comparison with other subtypes, notably clade B, which is primarily found in Europe and North America. Few studies have assessed cognitive impairment in antiretroviral therapy (ART) naïve men and women with HIV-1 clade C infection. In this study conducted in Northern India, differences in neuropsychological functioning were compared between 109 participants (70 men, 39 women) with untreated HIV-1 clade C infection and 110 demographically matched healthy controls (74 men, 36 women). A comprehensive neuropsychological battery was used to examine depression, self-assessment of functioning, and cognitive performance in six domains of functioning. Group differences were assessed by HIV-1 status and sex, controlling for age and education. Results indicated that cognitive deficits were substantially greater among male participants with HIV-1 clade C compared to male controls in all domains of cognitive functioning; in contrast, women with HIV-1 clade C had only minor deficits compared to healthy female participants. In addition, a larger proportion of men with HIV-1 clade C exhibited high levels of depression than women with HIV-1 clade C. These findings suggest that untreated HIV-1 clade C infection in men can have debilitating effects on neuropsychological function and depression, and stress the importance of facilitating rapid access to treatment to reduce the impact of HIV-1 infection.

RESUMEN

Despite increasing interest in Early-Infant and Early-Adolescent Medical Circumcision (EIMC and EAMC, respectively) in Zambia, parental willingness to have their sons undergo the procedure has not been explored. This study describes Zambian parents' perspectives on EIMC and EAMC. A total of N = 600 men and women (n = 300 couples) were recruited. Most parents, 89% and 83%, planned to have their newborn or adolescent sons circumcised, respectively, and 70% and 57% had plans for EIMC and EAMC, respectively. Most (91% for infants and 86% for adolescents) reported they were considering the pros and cons of circumcision. Parents' age (OR 1.05), having children living in one's home (OR 3.58), and lower education (OR 0.63) were associated with sons' circumcision. The minimal risks associated with circumcision and the lifetime benefits conferred underscore its contribution to public health in high HIV prevalence areas.


RESUMEN: A pesar del creciente interés en la Circuncisión Médica Temprana de Niños y Adolescentes (EIMC y EAMC, respectivamente, por su siglas en ingles) en Zambia, no se ha explorado la voluntad de los padres, de dar consentimiento, para que sus hijos se sometan al procedimiento. Este studio, describe las perspectivas de los padres de Zambia sobre EIMC y EAMC. Se reclutaron un total de N = 600 hombres y mujeres (n = 300 parejas) que esperaban tener un hijo. La mayoría de los padres, 89% y 83%, planeaban circuncidar a sus hijos recién nacidos o adolescentes, respectivamente, y 70% y 57% tenían planes para EIMC y EAMC, respectivamente. La mayoría (91% para bebés y 86% para adolescentes) informaron que estaban considerando las ventajas y desventajas de la circuncisión. La edad de los padres (OR 1,05), tener hijos viviendo en el hogar (OR 3,58) y menor educación (OR 0,63) se asociaron con la circuncisión de los hijos. Los riesgos mínimos asociados con la circuncisión y los beneficios conferidos de por vida subrayan su contribución a la salud pública en áreas de alta prevalencia del VIH.

RESUMEN

Mental health and substance use epidemics interact to create psychosocial syndemics, accelerating poor health outcomes. Using latent class and latent transition analyses, we identified psychosocial syndemic phenotypes and their longitudinal transition pathways among sexual minority men (SMM) in the Multicenter AIDS Cohort Study (MACS, n = 3,384, mean age 44, 29% non-Hispanic Black, 51% with HIV). Self-reported depressive symptoms and substance use indices (i.e., smoking, hazardous drinking, marijuana, stimulant, and popper use) at the index visit, 3-year and 6-year follow-up were used to model psychosocial syndemics. Four latent classes were identified: "poly-behavioral" (19.4%), "smoking and depression" (21.7%), "illicit drug use" (13.8%), and "no conditions" (45.1%). Across all classes, over 80% of SMM remained in that same class over the follow-ups. SMM who experienced certain psychosocial clusters (e.g., illicit drug use) were less likely to transition to a less complex class. These people could benefit from targeted public health intervention and greater access to treatment resources.

RESUMEN

Intravaginal practices (IVPs) refer to placing items (e.g., water, soap, commercial douches, fingers, rags) inside the vagina. IVPs have been shown to contribute to the development of bacterial vaginosis (BV) and may increase sexually transmitted infections and HIV risk. We developed the Intravaginal Practices Questionnaire (IVQ). The purpose of this study was to validate the IVQ, with the goal of establishing a consistent method of assessing IVP across studies. Women enrolled in this study (n = 180) were on average 30 years of age (SD = 8.32). Half (54%) identified as non-Hispanic, and 45% identified as Black; 41% reported lifetime IVP. Past month IVP use included commercial douches (9%), water (35%), fingers (41%), soap (21%), cloths/rags/wipes (10%), and vinegar (3%), which were placed in the vagina. No women used yogurt or herbs. An exploratory factor analysis indicated that a single-factor structure best explained the underlying constructs in participant responses in six endorsed items assessing commercial douches, water, fingers, soap, clothes/rags/ wipes, and vinegar use, suggesting that a common factor underlies these behaviors. All factor loadings were > 0.496. Cronbach's α was 0.99, suggesting that the reliability of the scale was excellent. Lastly, a total IVQ score was related to BV diagnosis (p = .007) as well as self-reported symptoms of BV (p = .034). Results illustrate that the IVQ has adequate psychometric properties. This tool may be used by public health experts and clinicians to identify IVPs that may potentially increase HIV risk.

RESUMEN

BACKGROUND: Polypharmacy, using five or more medications, may increase the risk of nonadherence to prescribed treatment. We aimed to identify the interrelationship between trajectories of adherence to antiretroviral therapy (ART) and polypharmacy. METHODS: We included women with HIV (aged ≥ 18) enrolled in the Women's Interagency HIV Study in the United States from 2014 to 2019. We used group-based trajectory modeling (GBTM) to identify trajectories of adherence to ART and polypharmacy and the dual GBTM to identify the interrelationship between adherence and polypharmacy. RESULTS: Overall, 1,538 were eligible (median age of 49 years). GBTM analysis revealed five latent trajectories of adherence with 42% of women grouped in the consistently moderate trajectory. GBTM identified four polypharmacy trajectories with 45% categorized in the consistently low group. CONCLUSIONS: The joint model did not reveal any interrelationship between ART adherence and polypharmacy trajectories. Future research should consider examining the interrelationship between both variables using objective measures of adherence.

RESUMEN

BACKGROUND: Elimination of vertical HIV Transmission (VHT) and maternal deaths are global health priorities. Male involvement is one of the most important factors that influences women's decisions, including the uptake of Prevention of vertical HIV transmission (P-VHT). We sought to understand not knowing a male partner's HIV status (MPHIVs) amongst women using services to prevent vertical HIV transmission in six South African districts with high antenatal HIV burden. METHODS: A mixed-methods cross-sectional study was conducted in six South African districts, and data collected through face-to-face interviews with women and focus group discussions (FGDs) with women or male partners. The quantitative data were analyzed using STATA SE-17.0 and an inductive approach was used for qualitative data analysis. RESULTS: Overall, 28.7% of women were unaware of their MPHIVs, while 25.3% and 46.0% knew the MPHIVs was positive or negative, respectively. In multivariable logistic regression, single marital status and unplanned pregnancy increased the odds of not knowing a MPHIVs while a woman's disclosure of her HIV status to the male partner reduced the odds. FDGs highlighted complexities around MPHIVs disclosure, e.g., reluctance to test for HIV and potential interventions including healthcare worker (HCW) assisted HIV disclosure. CONCLUSION: User-informed interventions to address MPHIVs non-disclosure amongst women of child-bearing age, particularly those at risk of unstable sexual partners and unplanned pregnancies, should be strengthened.

RESUMEN

We evaluated the psychometric properties of a modified version of the Vaccine Hesitancy Scale (VHS) among people with HIV (PWH) for COVID-19 vaccination in a cross-sectional study in the US. Self-report data from an online questionnaire were collected from a sample of N = 175 PWH. Participants were surveyed in English or Spanish regarding attitudes towards COVID-19 vaccination using the adapted VHS. Participants were on average 51.55 years of age (SD = 13.90) 55% were women. The reliability of the scale was acceptable (α = 0.72). An exploratory factor analysis showed that "Lack of confidence" and "Risks" explained 45.55% and 12.31% of the variance. Related items showed expected associations with these factors, supporting construct validity. Results illustrate that the modified VHS for COVID-19 vaccination has adequate psychometric properties. We replicated the original factor structure of the VHS and demonstrated adequate internal consistency and construct validity. Validated tools are essential to guide vaccination policy and campaigns towards populations at risk.


RESUMEN: En este estudio transversal, evaluamos las propiedades psicométricas de la Escala de Reticencia a la Vacunación (VHS, por sus siglas en inglés) para la vacuna contra el COVID-19 en personas con VIH (PCV) en los EE. UU. Los participantes (N = 175) respondieron a una encuesta en línea en inglés o en español, sobre las actitudes hacia la vacuna contra el COVID-19 utilizando una version adaptada de la VHS. La edad promedio de los participantes fue de 51,55 años (DE = 13,90;) y 55% eran mujeres. La fiabilidad de la escala fue aceptable (α = 0,72). Un análisis factorial exploratorio mostró que la "falta de confianza" y los "riesgos" explicaron el 45,55% y el 12,31% de la varianza. Los elementos relacionados mostraron asociaciones esperadas con dichos factores, apoyando la validez de la VHS adaptada para esta población. Los resultados ilustran que la VHS modificada para la vacuna contra el COVID-19 tiene propiedades psicométricas adecuadas. Replicamos la estructura factorial original de la VHS y demostramos una adecuada validez y consistencia interna. La validación de instrumentos de recolección de datos es esencial para orientar las políticas y campañas de vacunación para poblaciones en riesgo, tal como PCV.

RESUMEN

Although prior research has examined associations between blood pressure (BP), depression, and suicidal ideation, few studies have examined this in high-risk populations such as pregnant women with HIV (WHIV). The current study examined the association of BP with depression and suicidal ideation among pregnant WHIV (n = 217) in rural South Africa. BP data (measured ≤ 1 month before the study visit) was extracted from medical records. Depressive symptomatology and suicidal ideation were assessed using the Edinburgh Postnatal Depression Scale. Diastolic BP was positively associated with both suicidal ideation and depressive symptomatology, even after controlling for demographic variables, gestational age, and intimate partner violence. These findings suggest that WHIV with elevated BP may be at greater risk for antenatal depression and suicidal ideation. Future research should utilize longitudinal designs to examine potential mechanisms and the directionality of the relationship, as well as other contributing factors.


RESUMEN: Aunque investigaciones anteriores han examinado las asociaciones entre la presión arterial (PA), depresión e ideación suicida, pocos estudios han examinado esto en poblaciones de alto riesgo, como las mujeres embarazadas con VIH. El estudio actual examinó la asociación de la PA con la depresión y la ideación suicida entre mujeres embarazadas con VIH (n = 217) en zonas rurales de Sudáfrica. Los datos de PA (medidos ≤ 1 mes antes de la visita del estudio) se extrajeron de los registros médicos. La sintomatología depresiva y la ideación suicida se evaluaron mediante la Escala de depresión posnatal de Edimburgo. La PA diastólica se asoció positivamente tanto con la ideación suicida como con la sintomatología depresiva, incluso después de controlar variables demográficas, edad gestacional y violencia de la pareja íntima. Estos hallazgos sugieren que mujeres embarazadas con VIH con PA elevada puede tener un mayor riesgo de depresión prenatal e ideación suicida. Las investigaciones futuras deberían aprovechar diseños longitudinales para examinar los posibles mecanismos y la direccionalidad de la relación, así como otros factores contribuyentes.

RESUMEN

Bacterial vaginosis (BV) is the most common genital infection in women and is associated with an increased risk of sexually transmitted infections and HIV. This study uses a syndemic approach to evaluate factors associated with BV. Non-pregnant, HIV-negative, sexually active, cis-gender women aged 18-45 years living in Miami, Florida were recruited from Nov.2018- Jun.2021. Participants completed a sociodemographic and behavioral questionnaire along with gynecological examinations. BV was diagnosed by Amsel criteria and confirmed by a Nugent score ≥ 4. A syndemic score was calculated as the sum of factors associated with BV. The association between syndemic score and BV was assessed using logistic regression. Of 166 women included, 60.2% had BV. Race, ethnicity, education, vaginal sex, recent cannabis use, and reasons for intravaginal practices were included in the syndemic score. Higher odds of BV were found in women with a score of ≥ 3 compared to women with a score of 0/1. A higher syndemic score was associated with increased odds of having BV. Multilevel interventions to decrease BV are needed to decrease women's risk of acquiring HIV.


RESUMEN: La vaginosis bacteriana (VB) es la infección genital más común en mujeres y está asociada con un mayor riesgo de enfermedades de transmisión sexual (ETS) y de VIH. Este estudio utilizó un enfoque sindémico para evaluar factores asociados con VB. Entre noviembre del 2018 y junio del 2021, se reclutaron mujeres cisgénero de entre 18­45 años, que no estuvieran embarazadas, que fueran VIH negativas y sexualmente activas, y que vivieran en Miami, Florida. Las participantes completaron un cuestionario sociodemográfico y de comportamiento junto con un examen ginecológico. Se diagnosticó VB empleando los criterios de Amsel y se confirmó empleando el criterio de Nugent con una puntuación ≥ 4. La puntuación sindémica fue calculada como la suma de factores asociados con VB utilizando. La asociación entre la puntuación sindémica con VB se evaluó mediate una regresión logística. De 166 mujeres incluidas, 60.2% fueron diagnosticadas con VB. Los factores incluidos en la puntuación sindémica fueron la raza, etnia, educación, sexo vaginal, consumo reciente de cannabis, y el uso de prácticas intravaginales. Se encontraron mayores probabilidades de VB en mujeres con una puntuación ≥ 3 en comparación con aquellas con una puntuación de 0/1. Una puntuación sindémica alta se asoció con una mayor probabilidad de tener VB. Son necesarias intervenciones multinivel para disminuir la VB y disminuir el riesgo de que las mujeres contraigan ETS y VIH.

RESUMEN

This study aimed to examine intimate partner violence (IPV) as it relates to both partners' perceptions of IPV and sexual behaviors, considering how their IPV might be interdependent within the relationship dynamics. The sample consisted of 713 female-male dyads in which women were pregnant and living with HIV in rural South Africa. Using an actor-partner interdependence model (APIM), we examined the interdependent influence of psychological and physical IPV on men by their female partners and psychological and physical IPV on women by their male partners on sexual risk behavior. The APIM model found there were no actor (b = -0.06, SE = 0.05, p = .221) or partner (b = -1.2, SE = 0.06, p = .056) effects contributing to protected sex by female IPV victimization. In contrast, significant actor (b = -0.28, SE = 0.06, p < .001) and partner (b = -0.29, SE = 0.06, p < .001) effects for protection were related to male IPV victimization. The model also found that the covariate of female HIV disclosure was associated with both male (b = 0.5, SE = 0.12, p < .001) and female protected sexual intercourse (b = 0.58, SE = 0.1, p < .001). Female HIV disclosure was related to an increased likelihood of protected sex by both male and female partners. As male partners reported more IPV victimization, the likelihood of protected sex between male and female partners decreased.Trial registration: ClinicalTrials.gov identifier: NCT02085356.

RESUMEN

BACKGROUND: Transgender women (TGW) consistently show lower adherence to antiretroviral treatment (ART), than cisgender people (CP) living with HIV. This study examined sociodemographic and psychosocial factors associated with gender identity among individuals disengaged from HIV care in Argentina. METHODS: Data for this study was obtained at baseline from the Conexiones y Opciones Positivas en la Argentina 2 (COPA2) study. Forty-one TGW and 360 CP (177 male, 183 female) disengaged from HIV care completed questionnaires assessing sociodemographic information, severity of depressive symptoms, substance and alcohol use, patient-provider relationship quality, self-efficacy, ART adherence motivation, self-reported adherence, and treatment-related factors. Analyses included chi-square tests exploring the association between categorical variables and gender identity, and ANCOVAs comparing groups controlling for age. RESULTS: Being a TGW was associated with having only public health insurance; substance use, particularly cocaine; substance-related problems; and hazardous drinking. TGW showed more negative consequences related to substance use, more hazardous alcohol use, lower patient-provider relationship quality, and lower self-reported adherence, than CP. CONCLUSIONS: Harm reduction should be a key component in HIV care for TGW to address substance use. Health care teams should receive formal training in patient-provider communication skills and trans-specific competencies to enhance TGW's adherence and retention. Public policies to address structural factors that negatively affect TGW's adherence to ART are also needed.

RESUMEN

PURPOSE: Measuring perinatal depression in women with HIV poses a challenge to accurate assessment. South Africa has particularly high rates of perinatal depression, with antenatal depression rates ranging from 21 to 47% and postnatal depression rates ranging from 17 to 50%. With the goal of providing an examination of the psychometric properties of the Edinburgh Postnatal Depression Scale (EPDS) in a population at greater risk for depression, the current manuscript examined the factor structures and reliability of the English and Zulu versions of the EPDS among pre- and postnatal women with HIV in South Africa. METHODS: This study included n = 1179 women who completed the EPDS in Zulu (n = 709) and English (n = 470) antenatally, and n = 866 women were analyzed at 12-months after birth (n = 494 in Zulu and n = 372 in English). RESULTS: Using factor analytic and item response theory approaches, the English and Zulu versions of the EPDS were compared. Although a few items performed poorly, particularly item 4, the construct validity of the English and Zulu versions of the pre- and postnatally administered EPDS was supported; the reliability of the scale was also supported, with adequate reliability in Zulu and English ante-natally (α = .78), and postnatally (α = .82 and α = .77 respectively). DISCUSSION: This study contributes to improved measurement of depressive symptoms among vulnerable women in a resource constrained setting. The early and accurate detection of depressive symptoms ante- and postnatally among perinatal women living with HIV can facilitate increased treatment which may in turn help prevent the negative maternal and neonatal outcomes associated with depression.

RESUMEN

Management of cardiovascular disease risk requires many lifestyle changes involving diet, smoking, and exercise. Individuals with arterial plaque are encouraged to adopt these changes to promote longevity through a variety of interventions. This study examined behavioral changes in response to the standard of care after detection of arterial plaque, specifically among HIV-infected cocaine users. 127 individuals (HIV - COC - n = 43, HIV + COC - n = 19, HIV + COC + n = 35, HIV - COC + n = 30) were followed after a standard of care intervention and assessed 1 and 2 years later on a variety of lifestyle (diet, exercise, smoking) and physiological (blood pressure, body mass index, number of arterial plaques) outcomes. Arterial plaque was found to increase over time (b = 0.003, SE = 0.002, p = .031), and a composite measure of cardiovascular disease risk did not change (b = - 0.004, SE = 0.01, p = .548). Following provision of a standard of care cardiovascular risk reduction intervention, important health behaviors related to CVD risk were resistant to change among both those HIV-infected and uninfected and among cocaine users and non-users.


RESUMEN: El manejo del riesgo para enfermedades cardiovasculares requiere muchos cambios en el estilo de vida, como dieta, dejar de fumar, y ejercicio. Se les recomienda a las personas, con placa arterial, adoptar estos cambios a través de una variedad de intervenciones. Este estudio examinó los cambios de comportamiento, en respuesta al estándar de atención, después de la detección de la placa arterial, específicamente entre los usuarios de cocaína infectados con VIH. 127 individuos (HIV − COC − n = 43, HIV + COC − n = 19, HIV + COC + n = 35, HIV − COC + n = 30) fueron seguidos después de una intervención de atención estándar y sus resultados fisiológicos (presión arterial, índice de masa corporal, número de placas arteriales) fueron evaluados 1 y 2 años después. Encontramos que la placa arterial aumento con el tiempo (b = 0.003, SE = 0.002, p = .031), y una formula que calcula el de riesgo de enfermedad cardiovascular no cambió (b = − 0.004, SE = 0.01, p = .548). Tras la provisión de una intervención estándar de atención para la reducción del riesgo cardiovascular, los comportamientos de salud importantes relacionados con el riesgo de enfermedades cardiovasculares fueron resistentes al cambio tanto entre los infectados y no infectados por el VIH como entre los usuarios y no usuarios de cocaína.

RESUMEN

Disclosure of HIV serostatus is beneficial for women, their partners, and their infants as it enables women to actively participate in preventative care (Hodgson et al. in PLoS ONE 9(11):e111421, 2014; Odiachi et al. in Reprod Health 15(1):36, 2018). Therefore, it is important that interventions addressing HIV prevention include elements that foster disclosure of HIV to partners. This study conducted in South Africa utilizes the "Protect Your Family" (PYF) behavioral intervention and compares Prevention of Mother to Child Transmission (PMTCT) among women participating in the program versus those in a control program. Within both groups, male partners were either present or not present for the intervention. The purpose of this study was to examine differential disclosure over time for individuals in the different conditions and partner involvement. A firth logistic regression revealed an interaction in the experimental condition with male partners participating (b = - 2.84, SE = 1.56, p = .012), in which female participants were less likely to disclose their HIV status over time. Findings from this study illustrate that additional efforts are needed to empower women to disclose their HIV status.


RESUMEN: Revelar su estado serológico del VIH a sus parejas es beneficioso para las mujeres, sus parejas y sus bebés, ya que les permite a las mujeres participar activamente en atención preventiva (Hodgson et al. in PLoS ONE 9(11):e111421, 2014; Odiachi et al. in Reprod Health 15(1):36, 2018). Por lo tanto, es importante que las intervenciones que aborden la prevención del VIH incluyan elementos que fomenten la revelación del estado serológico del VIH de las mujeres a sus parejas. Este estudio realizado en Sudáfrica utiliza la intervención conductual "Protege a tu familia" (PYF por sus siglas en Ingles) y compara la prevención de la transmisión de madre a hijo (PMTCT por sus siglas en Ingles) entre mujeres que participaron en el programa y las que participaron en un programa de control. Dentro de ambos grupos, los compañeros masculinos estuvieron presentes o no presentes para la intervención. El propósito de este estudio fue examinar la revelación diferente a lo largo del tiempo para individuos en diferentes condiciones y participación de pareja. Una regresión logística reveló de Firth una interacción en la condición experimental con la participación de parejas masculinas (b = − 2.84, SE = 1.56, p = .012), en las cuales las participantes femeninas tenían menos probabilidades de revelar su estado de VIH a lo largo del tiempo. Los resultados de este estudio ilustran que se necesitan esfuerzos adicionales para motivar a las mujeres a revelar su estado de VIH.

RESUMEN

Male partner involvement (MPI) during the prenatal and postnatal periods has been proven to have a beneficial effect on infant development. Infants born to HIV seropositive mothers with lacking or no prenatal and postnatal male partner support may be at a higher risk for adverse developmental outcomes. This study examined the effect of MPI on cognitive, communicative, fine, and gross motor development in 160 infants born to HIV seropositive mothers attending Prevention of Mother-to-Child Transmission of HIV (PMTCT) services in rural South Africa. Results of the bivariate logistic regression showed that both prenatal (OR 1.13; 95% CI 1.01, 1.26; p < 0.05) and postnatal MPI (at 12 months) (1.19; 1.07, 1.31; p < 0.005) were associated with risk for delayed gross motor development in HIV exposed infants. Decreased postnatal MPI (0.85; 0.75, 0.98; p < 0.05) was significantly associated with risk for delayed cognitive development. Not living together with a male partner (2.01; 1.06, 3.80; p < 0.05) was significantly associated with risk for delayed cognitive development. In the multivariate logistic regression analysis, decreased postnatal MPI (0.85; 0.75, 0.98; p < 0.05) was significantly associated with risk for delayed cognitive development. On the other hand, postnatal MPI (1.30; 1.12, 1.50; p < 0.005) was associated with risk for delayed gross motor development among HIV exposed infants. Increased MPI can have beneficial effects on infants' cognitive development. Interventions in PMTCT programs should promote increased prenatal and postnatal MPI to improve cognitive development in HIV exposed infants.

RESUMEN

The COVID-19 pandemic poses a risk to mental health and may disproportionately affect people living with HIV (PLWH). This study examined the interaction of social support and resilient coping in predicting depressive symptoms among PLWH. PLWH residing in Buenos Aires, Argentina and in Miami, Florida (US) were asked to complete an anonymous survey on the impact of COVID-19. Statistical analysis included ordinary least squares regression. A total of 1,554 participants were included. Mean age was 47.30 years; 63.70% were men. A test of three-way interaction of social support × resilient coping × study site indicated differences by site (b = -0.63, p = 0.04, 95%CI [-1.24, -0.02]). In Argentina, higher levels of social support and resilient coping were associated with lower depressive symptoms. Lower levels of social support and resilient coping were associated with higher depressive symptoms. The impact of COVID-19 on mental health illustrates the need for developing innovative strategies to support resilience and to enhance coping with stress and adversity among PLWH.


RESUMEN: La pandemia de COVID-19 presenta riesgos importantes para la salud mental y puede afectar desproporcionadamente a personas con VIH. Este estudio examinó el efecto entre el apoyo social y la resiliencia para afrontar situaciones difíciles en predecir síntomas depresivos en personas con VIH. Personas con VIH residentes de Buenos Aires (Argentina) y Miami, Florida (EE.UU) completaron una encuesta anónima sobre el impacto del COVID-19. El análisis estadístico incluyó un modelo clásico de regresión lineal con mínimos cuadrados ordinarios. Se incluyeron 1554 participantes. La edad promedio fue 47.30 años y 63.7% eran hombres. La prueba de interacción de apoyo social × resiliencia para hacer frente a situaciones difíciles × país indicó diferencias entre países (b = −0.63, p = 0.043, IC 95% [1.24, −0.02]). En Argentina, los participantes con mayor apoyo social y resiliencia para hacer frente a situaciones difíciles mostraron síntomas depresivos más bajos; y aquellos con menor apoyo social y resiliencia para hacer frente a situaciones difíciles, mostraron síntomas depresivos más altos. Este efecto no se observó en los participantes de Miami. El impacto de COVID-19 en la salud mental en personas con VIH ilustra la necesidad de desarrollar estrategias innovadoras para apoyar la resiliencia y mejorar el enfrentamiento del estrés y la adversidad.

RESUMEN

Motivational interviewing (MI) utilizes a patient-centered approach to address patient ambivalence about treatment and has been found to improve treatment ART adherence among patients living with HIV disengaged from care. This study examined MI training for clinicians, uptake, and sustainability over time. Clinics (n = 7) with N = 38 physicians were randomized to condition (MI, Enhanced Standard of Care). Physicians completed video- recorded patient consultations at baseline and 6, 12, and 18-month follow-up. MI condition physicians had greater relational and technical scores over time and were more likely to adhere to and sustain MI over time. Overall, physicians found the MI training highly acceptable and were able to sustain their skills. Results illustrate the feasibility of MI training, implementation, and sustainment over 18 months. Findings support previous research in Argentina in which trained physicians found MI useful with challenging patients. Broader implementation of MI among HIV care physicians in Argentina is merited.


RESUMEN: La entrevista motivacional (EM) es una intervención con enfoque en el paciente que sirve para abordar la ambivalencia del paciente sobre el tratamiento. Se ha descubierto que EM mejora la adherencia al tratamiento antirretroviral en pacientes con VIH y que no están recibiendo tratamiento. En este estudio se examinó la capacitación de EM entre médicos, como también la aceptación y la sostenibilidad de EM a lo largo del tiempo. Las clínicas (n = 7) con N = 38 médicos se asignaron al azar a la condición (EM o estándar de atención mejorada). Los médicos hicieron consultas de pacientes, las cuales fueron grabadas en video al inicio del estudio y a los 6, 12 y 18 meses de seguimiento. Los médicos de la condición de EM obtuvieron puntuaciones relacionales y técnicas más altas a lo largo del tiempo y fueron más propensos ha adherirse y usar la EM con el tiempo. En general, los médicos consideraron que la formación en EM era muy aceptable y pudieron mantener sus habilidades. Los resultados ilustran la viabilidad de la capacitación, implementación y mantenimiento de la EM durante 18 meses. Los descubrimientos sustentan investigaciones anteriores en Argentina en las que médicos capacitados encontraron que la EM era útil para pacientes desafiantes. Una implementación más amplia de la EM entre los médicos de atención del VIH en Argentina es necesaria para mejorar el tratamiento de personas con VIH.
