RESUMO

Intimate partner violence (IPV) and HIV are serious and related public health problems that detrimentally impact women's health. Because women who experience IPV are more likely to acquire HIV, it is critical to promote HIV prevention strategies, such as HIV pre-exposure prophylaxis (PrEP), that increase autonomy. This study of cisgender women eligible for HIV PrEP took place between 2017 and 2019 in Philadelphia and New York City. This study aimed to examine the relationship between four types of IPV (control, psychological, physical, sexual) and intention to start PrEP among PrEP-eligible cisgender women and assess the extent to which HIV relevant factors moderated the association between IPV experience and intention to start PrEP. In this sample of PrEP-eligible women (n = 214), 68.7% indicated intention to start PrEP in the next 3 months. Ethnicity was strongly associated with intention to start PrEP, with Hispanic women having the highest odds of intending to start PrEP in the next 3 months. Having a controlling partner significantly predicted intention to start PrEP. Women with more than one sex partner and a controlling partner had higher odds of intending to start PrEP as compared with those who had one or no partners and had no IPV control. These findings point to a need for patient-centered interventions that address the need for safety and autonomy among cisgender, PrEP-eligible women.

RESUMO

Despite evidence supporting HIV pre-exposure prophylaxis (PrEP) effectiveness, very few women with opioid use disorder (OUD) take PrEP. Interventions that improve medication assisted treatment (MAT) uptake and adherence may also be beneficial for PrEP. The reSET-O mobile phone app is a component of the evidence-based Therapeutic Education System, which improves retention and abstinence for people with OUD. To better understand use of this mobile health tool as a support for PrEP among women with OUD, pre-implementation contextual inquiry is needed. Therefore, we set out to assess target user characteristics, implementation barriers, feasibility, and acceptability of reSET-O. We recruited women with OUD receiving care from a community-based organization in Philadelphia to complete semi-structured interviews. All participants were prescribed reSET-O. We interviewed 20 participants (average age 37 years; 70% white, 15% Hispanic, 5% Black) from 5/2021 to 2/2022. We used an integrated analysis approach combining modified grounded theory and implementation science constructs. Half reported recent injection drug use, and 6 were taking buprenorphine. Mental health symptoms were common, and half described engaging in transactional sex. The majority expressed strong interest in PrEP. Participants reported the app would be highly acceptable for PrEP and MAT adherence support, but only two redeemed the prescription. The most common barriers included phone and internet access. Our findings highlight potential implementation challenges for the use of such an app to support PrEP use in this population. Poor uptake of the app at follow-up indicates that initial prescription redemption is a major barrier to reSET-O implementation.

RESUMO

HIV pre-exposure prophylaxis (PrEP) uptake among cisgender women in the United States is low. Just4Us, a theory-based counseling and navigation intervention, was evaluated in a pilot randomized controlled trial among PrEP-eligible women (n = 83). The comparison arm was a brief information session. Women completed surveys at baseline, post-intervention, and at three months. In this sample, 79% were Black, and 26% were Latina. This report presents results on preliminary efficacy. At 3 months follow-up, 45% made an appointment to see a provider about PrEP; only 13% received a PrEP prescription. There were no differences in PrEP initiation by study arm (9% Info vs. 11% Just4Us). PrEP knowledge was significantly higher in the Just4Us group at post-intervention. Analysis revealed high PrEP interest with many personal and structural barriers along the PrEP continuum. Just4Us is a promising PrEP uptake intervention for cisgender women. Further research is needed to tailor intervention strategies to multilevel barriers.Clinicaltrials.gov registration NCT03699722: A Women-Focused PrEP Intervention (Just4Us).


RESUMEN: La aceptación de la profilaxis previa a la exposición (PrEP) al VIH entre las mujeres cisgénero en los Estados Unidos es baja. Just4Us, una intervención de asesoramiento y navegación basada en la teoría, se evaluó en un ensayo piloto controlado aleatorizado con mujeres aptas para la PrEP (n = 83). El brazo de comparación fue una breve sesión de información. Las mujeres completaron encuestas al inicio, después de la intervención ya los 3 meses. En la muestra, el 79% eran negros y el 26% eran latinas. Este informe presenta resultados sobre la eficacia preliminar. A los 3 meses de seguimiento, el 45% hizo una cita para ver a un proveedor acerca de la PrEP; solo el 13% recibió una receta de PrEP. No hubo diferencias en el inicio de la PrEP por brazo de estudio (9% Info frente a 11% Just4Us). El conocimiento fue significativamente mayor en el grupo Just4Us después de la intervención. El análisis reveló un alto interés por la PrEP con muchas barreras personales y estructurales a lo largo del continuo de la PrEP. Just4Us es una prometedora intervención de adopción de PrEP para mujeres cisgénero. Se necesita más investigación para adaptar las estrategias de intervención a las barreras multinivel.

RESUMO

BACKGROUND: The burden of heart failure (HF) is unequally distributed among population groups. Few study authors have described social determinants of health (SDoH) enabling/impeding self-care. AIM: The aim of this study was to explore the relationship between SDoH and self-care in patients with HF. METHODS: Using a convergent mixed-methods design, we assessed SDoH and self-care in 104 patients with HF using the Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences (PRAPARE) and the Self-Care of HF Index v7.2 with self-care maintenance, symptom perception, and self-care management scales. Multiple regression was used to assess the relationship between SDoH and self-care. One-on-one in-depth interviews were conducted in patients with poor (standardized score ≤ 60, n = 17) or excellent (standardized score ≥ 80, n = 20) self-care maintenance. Quantitative and qualitative results were integrated. RESULTS: Participants were predominantly male (57.7%), with a mean age of 62.4 ± 11.6 years, with health insurance (91.4%) and some college education (62%). Half were White (50%), many were married (43%), and most reported adequate income (53%). The money and resources core domain of PRAPARE significantly predicted self-care maintenance ( P = .019), and symptom perception ( P = .049) trended significantly after adjusting for other PRAPARE core domains (personal characteristics, family and home, and social and emotional health) and comorbidity. Participants discussed social connectedness, health insurance coverage, individual upbringing, and personal experiences as facilitators of self-care behavior. CONCLUSION: Several SDoH influence HF self-care. Patient-specific interventions that address the broader effects of these factors may promote self-care in patients with HF.

RESUMO

We aimed to elucidate the specific roles and responsibilities of expert clients in service delivery among adolescents living with HIV in Eswatini, and to provide recommendations for enhancing adolescent service provision among expert clients and similar lay health workers throughout low- and middle-income countries. An exploratory qualitative descriptive methodology using conventional content analysis was used to meet our study aims. We recruited 20 expert clients and 12 key informants (programme managers, programme coordinators and nurses) to participate in semi-structured interviews, and we arranged four focus group discussions among adolescents living with HIV with seven to ten participants per focus group. Adherence counselling in clinical and community settings was considered paramount to the roles and responsibilities of expert clients with regard to adolescent-specific HIV service delivery. The following recommendations were made to enhance expert client service delivery practices among adolescents: (1) training in adolescent developmental, sexual and reproductive needs; (2) training to enhance clinical knowledge and skills; (3) additional work equipment and compensation; and d) more parent and guardian engagement in their work. While expert clients meet the needs of adolescents living with HIV in several capacities, they require additional resources, skills and training to improve their work, especially in the realm of sexual and reproductive health. Future research is needed to evaluate the impact of expert client service delivery on adolescent health outcomes.

RESUMO

The underutilization of pre-exposure prophylaxis (PrEP) among cisgender women in the U.S. limits this population's ability to reduce their risk for HIV infection, especially within the unique individual, social and structural systems they navigate. There is a need to identify the relevant multi-level barriers and facilitators to PrEP use among cisgender women to inform theory-guided efforts that address HIV disparities by race/ethnicity among cisgender women. Guided by the Integrated Behavioral Model and the Behavioral Model of Vulnerble Populations we conducted 41 interviews with PrEP eligible cisgender women in New York City and Philadelphia. Directed content analysis identified 11 modal behavioral beliefs crucial to PrEP uptake, including anticipated negative social consequences, 5 normative beliefs centered on available social supports, and 9 control beliefs such as anticipated barriers such as cost. Awareness and knowledge of PrEP as a biobehavioral HIV prevention method is limited for this sample. Through conventional content analysis we identified interpersonal and structural barriers to PrEP uptake including lack of partner support, transportation, mental health challenges, and challenges in accessing PrEP care. Potential solutions to structural barriers were enumerated along with implications for future intervention work and public health programming.

RESUMO

Since the beginning of the HIV epidemic in the USA, effective interventions to reduce HIV risk among cisgender women have been lacking. Although oral HIV pre-exposure prophylaxis (PrEP) is effective in pharmacologically preventing HIV infection, there is a gap between the recommended use of PrEP and PrEP uptake among eligible women. This study aimed to identify the role of patient-provider communication in PrEP decision-making among women considering PrEP. Semi-structured in-depth interviews were conducted with 41 PrEP-eligible women in Philadelphia and New York City. A thematic analysis of the responses was conducted, and a conceptual model developed and confirmed as analysis continued. Of the women interviewed, 53.6% were African American and 29.3% were Latina. Women noted that having a trusting relationship with their health care provider, receiving a tailored recommendation for PrEP based upon their specific needs and using their health care provider as support were crucial facilitators of PrEP decision-making. Lack of provider knowledge about PrEP, perceived health care provider stigma about their drug use and sexual activity, and lack of care continuity were all identified as barriers to effective communication. Study findings can inform future interventions to enhance patient-provider communication about PrEP and increase PrEP uptake among women.

RESUMO

OBJECTIVE: US disparities in pediatric type 1 diabetes treatment and outcomes are increasing disproportionately among Black youth and compounded for youth from single parent homes. Despite worsened outcomes, Black youth from single parent homes and their caregivers are underrepresented in pediatric type 1 diabetes research. The purpose of this study was to understand the social determinants of health (SDOH) barriers that may contribute to health disparities and family management in Black youth with type 1 diabetes from single parent homes. RESEARCH DESIGN AND METHODS: A three-phase mixed methods study with self-identified Black single parents of youth with type 1 diabetes from an urban US pediatric diabetes center was conducted. Focus groups and interviews informed development of a parent-generated survey of SDOH barriers to diabetes management. Survey results are presented. RESULTS: A resulting 71 item parent-generated survey was administered to 105 parents. Among all items, most problematic SDOH barriers included lack of social support, managing parent/child diabetes-related stress, difficulties accessing diabetes supplies, pain management, cost of food and diabetes camp, need to take time off from work, lack of skilled school staff, school absences and unsafe neighborhoods. Structural racism related to child welfare reporting, and police targeting were also notable concerns. CONCLUSIONS: There is a critical need for clinical, community, and policy-related research and interventions, designed to reduce type 1 diabetes racial health disparities by addressing the impacts of SDOH as drivers of family management outcomes among Black youth from single parent families.

RESUMO

Chronic illnesses cause significant mortality in adults. Caregivers (spouses, adult children, friends) support adults with chronic illness in multiple ways, for instance through support of their autonomous decisions about how and why to engage in self-care. AIM: To examine interventions designed to improve the health and well-being of adults with chronic illness by enhancing the autonomy supportive behaviours of caregivers. DESIGN: Systematic review of randomized controlled trials with narrative synthesis. DATA SOURCES: All available dates of publication through August 2020 conducted in PubMed, Medline, Ageline, PsychInfo, and CINAHL. METHODS: Randomized controlled interventions of adults with chronic illness and their caregivers with content to enhance caregiver autonomy support were included. Interventions involving healthcare personnel, adults without self-care capacity, or not published in English were excluded. Quality was appraised using Joanna Briggs Institute recommendations. Common themes in autonomy support and associated outcomes (e.g., self-care, social support) were synthesized. RESULTS: Search identified 1,426 studies with 16 included in review (N = 2,486 dyads). Methodological quality was moderate. Successful interventions were skills-based, targeted various communication styles, contained in-person elements, and involved nurses. Half of the interventions assessed autonomy support outcomes; 63% (5 of 8) of these improved autonomy support. Results were generally positive for social support, mixed for self-care, and null for caregiver burden. Heterogeneity and complexity of studies limited attribution of effects. CONCLUSION: Behavioural interventions designed to enhance dyadic caregiver interpersonal communication to be autonomy supportive may positively influence caregiver skills and chronic illness outcomes. Future studies of autonomy support are needed to identify core intervention components. IMPACT: This is the first systematic review examining interventions promoting caregiver to care-receiver autonomy support. Modifying interpersonal communication to be autonomy supportive has potential to improve chronic illness outcomes. Findings can inform how clinicians and investigators enlist caregiver autonomy support to encourage behaviour change.

RESUMO

Women comprise 19% of those newly diagnosed with HIV in the U.S. There is a wide gap between recommended use of pre-exposure prophylaxis (PrEP) and actual uptake among women who are eligible for PrEP. In order to identify women's beliefs and intentions about starting PrEP, a survey, informed by the reasoned action approach, was administered to 160 cisgender PrEP-eligible women, age 18-55, in Philadelphia and New York City. The mean age was 40.2 years (SD = 11.78), 44% had completed high school, 75% were unemployed, and 85% experienced financial instability in the past 3 months. Multivariate linear regression analyses identified sets of behavioral and normative beliefs associated with intention to start PrEP in the next 3 months. Behavioral beliefs reflected views about PrEP benefits such as preventing HIV, and normative beliefs reflected perceptions of support or lack thereof from others including partners, friends, mother, and children. These findings can be used to inform interventions to foster greater PrEP uptake among women.

RESUMO

Certified nursing assistants (CNAs) provide the majority of direct care to nursing home residents in the United States and, therefore, are keys to ensuring optimal health outcomes for this frail older adult population. These diverse direct care workers, however, are often not recognized for their important contributions to older adult care and are subjected to poor working conditions. It is probable that social-based discrimination lies at the core of poor treatment toward CNAs. This review uses perspectives from critical social theory to explore the phenomenon of social-based discrimination toward CNAs that may originate from social order, power, and culture. Understanding manifestations of social-based discrimination in nursing homes is critical to creating solutions for severe disparity problems among perceived lower-class workers and subsequently improving resident care delivery.

RESUMO

Intimate partner violence (IPV), the physical, sexual, psychological abuse or control by a former or current intimate partner, affects almost one-third of women in the United States. IPV exposure can result in many negative outcomes including physical injury, increased stress, and depression. Currently, there is a small, but, growing body of literature examining the link between IPV victimization and increased cardiovascular disease (CVD) risk among young adult women. To better prevent this negative outcome, it is imperative to understand what factors associated with IPV victimization may be increasing this risk. A secondary analysis of Wave IV of the Add Health study was conducted to examine possible factors mediating past year IPV exposure and 30-year CVD risk score including perceived stress, depressive symptoms, and alcohol dependence among a representative sample of young adult women in the United States. Multiple mediation analyses were run to examine the possible mediating factors in the relationship between IPV and CVD risk. In a multiple mediation model, the indirect effect of perceived stress became insignificant when depressive symptoms were introduced. The findings of this study reveal that 30-year CVD risk in the context of IPV victimization should continue to be examined among this population. The mediation models suggested the importance of stress and depression in the context of IPV and heart health. Screening for depression among women exposed to IPV should be considered as an important intervention point, not only to mitigate mental health issues, but to also help prevent the development of cardiovascular disease.

RESUMO

Scientific advances in health care have been disproportionately distributed across social strata. Disease burden is also disproportionately distributed, with marginalized groups having the highest risk of poor health outcomes. Social determinants are thought to influence health care delivery and the management of chronic diseases among marginalized groups, but the current conceptualization of social determinants lacks a critical focus on the experiences of people within their environment. The purpose of this article was to integrate the literature on marginalization and situate the concept in the framework of social determinants of health. We demonstrate that social position links marginalization and social determinants of health. This perspective provides a critical lens to assess the societal power dynamics that influence the construction of the socio-environmental factors affecting health. Linking marginalization with social determinants of health can improve our understanding of the inequities in health care delivery and the disparities in chronic disease burden among vulnerable groups.

RESUMO

This study investigates what needs to be considered in our current health services to appropriately respond to abused Korean immigrant women. Using a community-based participatory approach, this qualitative interpretive description analyzed counseling documents and semi-structured interviews. Data analyses suggested that intimate partner violence (IPV) screening for ethnic minority women in health care settings can be improved by informing patients about the role of health care providers in addressing IPV, establishing rapport before IPV screening, assuring confidentiality is maintained, respecting Korean immigrant women's unique perspectives and response toward IPV, providing translation services, and collaborating with ethnic minority women's community organizations.

RESUMO

BACKGROUND: Intimate partner violence directed at women by men continues to be a global concern. However, little is known about the factors associated with perpetrating intimate partner violence among heterosexual men. PURPOSE: History of childhood sexual abuse and other sociodemographic variables were examined as potential factors associated with severe intimate partner violence perpetration toward women in a sample of heterosexual men in South Africa. METHODS: Longitudinal logistic generalized estimating equations examined associations of childhood sexual abuse and sociodemographic variables at baseline with intimate partner violence perpetration at subsequent time points. RESULTS: Among participants with a steady female partner, 21.81 % (190/ 871) reported perpetrating intimate partner violence in the past year at baseline. Having a history of childhood sexual abuse (p < .001), binge drinking (p = .002), being employed (p = .050), and more difficulty controlling sexual impulses in order to use a condom (p = .006) at baseline were associated with self-reported intimate partner violence perpetration in the past year at subsequent time points. CONCLUSIONS: With high levels of recent severe physical and/or sexual intimate partner violence perpetration in South Africa, comprehensive interventions are urgently needed. To more fully address gender-based violence, it is important to address associated factors, including exposure to childhood sexual abuse that could impact behavior later in life and that have long-lasting and deleterious effects on men and their female partners.

RESUMO

Drug-reward cues trigger motivational circuitry, a response linked to drug-seeking in animals and in humans. Adverse life events have been reported to increase sensitivity to drug rewards and to bolster drug reward signaling. Therefore, we hypothesized that cocaine-dependent individuals with prior emotional, physical and sexual abuse might have a heightened mesolimbic brain response to cues for drug reward in a new brief-cue probe. Cocaine-dependent human individuals (N = 68) were stabilized in an inpatient setting and then completed an event-related blood-oxygen-level dependent functional magnetic resonance imaging task featuring 500-ms evocative (cocaine, sexual, aversive) and comparator (neutral) cues. Responses to three questions about emotional, physical and sexual abuse from the Addiction Severity Index were used to divide the patients into subgroups (history of Abuse [n = 40] versus No Abuse [n = 28]). When subjects were grouped by the historical presence or absence of emotional, physical or sexual abuse, the Abuse group showed a heightened midbrain, thalamic, caudate, and caudal orbitofrontal cortex response to cocaine cues; a similar result was found in other evocative cues, as well. These findings are the first reported for a 500-ms cocaine-cue probe, and they highlight the ability of very brief evocative cues to activate the brain's motivational circuitry. Although all participants had severe cocaine use disorders, individuals reporting prior abuse had a heightened mesolimbic response to evocative cues. To our knowledge, this is the first study in humans linking a history of abuse to a brain vulnerability (heightened mesolimbic response to drug cues) previously shown to contribute to drug-seeking.

RESUMO

BACKGROUND: Adolescents living in South Africa are at high risk for HIV and other sexually transmitted diseases (STDs). The present study sought to identify correlates of curable STD incidence among a cohort of adolescents in Eastern Cape Province, South Africa. METHODS: Data were collected in conjunction with an HIV/STD prevention intervention randomized controlled trial. At 54 months postintervention, curable STD incidence (gonorrhea, chlamydial infection, and trichomoniasis) was assayed and self-report measures of potential correlates of STD incidence were collected. RESULTS: Participants were adolescents reporting at least 1 sexual partner in the past 3 months (n = 659). As expected, univariate analyses revealed that girls were more likely than boys to have an STD. In addition, intimate partner violence, unprotected sex, and having older partners were associated with incident STD. In Poisson multiple regression analyses, sex (risk ratio [RR], 4.00; 95% confidence interval [CI], 2.51-6.39), intimate partner violence (RR, 1.23; 95% CI, 1.12-1.35), unprotected sex (RR, 1.42; 95% CI, 1.09-2.01), and multiple partners (RR, 1.70; 95% CI, 1.11-2.61), but not partner's age (RR, 1.00; 95% CI, 0.94-1.07) were associated with incident STD, adjusting for 42-month STD prevalence. Binge drinking, forced sex, and age were unrelated to STD incidence in both analyses. Interactions between sex and the hypothesized correlates were nonsignificant, suggesting that sex did not modify these relationships. CONCLUSIONS: Interventions to reduce HIV/STD incidence among adolescents in South Africa should address the risk associated with sex, unprotected sex, intimate partner violence, and multiple partnerships.

RESUMO

OBJECTIVE: Increasing physical activity is an important public-health goal worldwide, but there are few published mediation analyses of physical-activity interventions in low-to-middle-income countries like South Africa undergoing a health transition involving markedly increased mortality from non-communicable diseases. This article reports secondary analyses on the mediation of a theory-of-planned-behavior-based behavioral intervention that increased self-reported physical activity in a trial with 1181 men in Eastern Cape Province, South Africa. METHOD: Twenty-two matched-pairs of neighborhoods were randomly selected. Within pairs, neighborhoods were randomized to a health-promotion intervention or an attention-matched control intervention with baseline, immediate-post, and 6- and 12-month post-intervention assessments. Theory-of-planned-behavior constructs measured immediately post-intervention were tested as potential mediators of the primary outcome, self-reported physical activity averaged over the 6- and 12-month post-intervention assessments, using a product-of-coefficients approach in a generalized-estimating-equations framework. Data were collected in 2007-2010. RESULTS: Attitude, subjective norm, self-efficacy, and intention were significant mediators of intervention-induced increases in self-reported physical activity. The descriptive norm, not affected by the intervention, was not a mediator, but predicted increased self-reported physical activity. CONCLUSION: The results suggest that interventions targeting theory-of-planned-behavior constructs may contribute to efforts to increase physical activity to reduce the burden of non-communicable diseases among South African men.

RESUMO

AIMS AND OBJECTIVES: In this critical literature review, we examine evidence-based interventions that target sexual behaviours of 18- to 25-year-old emerging adult women. BACKGROUND: Nurses and clinicians implement theory-driven research programmes for young women with increased risk of HIV/AIDS and sexually transmitted infections. Strategies to decrease transmission of HIV and sexually transmitted infections are rigorously evaluated and promoted by public health agencies such as the United States Centers for Disease Control and Prevention. While many interventions demonstrate episodic reductions in sexual risk behaviours and infection transmission, there is little evidence they build sustainable skills and behaviours. Programmes may not attend to contextual and affective influences on sexual behaviour change. DESIGN: Discursive paper. METHODS: We conducted a conceptually based literature review and critical analysis of the Centers for Disease Control and Prevention's best-evidence and good-evidence HIV behavioural interventions. In this review, we examined three contextual and affective influences on the sexual health of emerging adult women: (1) developmental age, (2) reproduction and pregnancy desires and (3) sexual security or emotional responses accompanying relationship experiences. RESULTS: Our analyses revealed intervention programmes paid little attention to ways age, desires for pregnancy or emotional factors influence sexual decisions. Some programmes included 18- to 25-year-olds, but they made up small percentages of the sample and did not attend to unique emerging adult experiences. Second, primary focus on infection prevention overshadowed participant desires for pregnancy. Third, few interventions considered emotional mechanisms derived from relationship experiences involved in sexual decision-making. CONCLUSIONS: Growing evidence demonstrates sexual health interventions may be more effective if augmented to attend to contextual and affective influences on relationship risks and decision-making. Modifying currently accepted strategies may enhance sustainability of sexual health-promoting behaviours. RELEVANCE TO CLINICAL PRACTICE: This study provides nurses and public health educators with recommendations for broadening the content of sexual health promotion intervention programming.

RESUMO

AIM: The aim of this study was to identify relationship dynamics that influences the use of STI/HIV testing among young, urban African American women. BACKGROUND: Increasing STI/HIV testing is a key prevention strategy, but more research is needed to identify barriers to testing for young women such as intimate partner violence (IPV). METHODS: Thirty semi-structured interviews were conducted with African American women ages 18-24. Content analysis was used. RESULTS: Women in choice-restricted relationships were unable to negotiate safer sex practices and testing was viewed as the best option. Women in relationships where the desire to use condoms was mutual used STI and HIV testing as a sign of trust building that preceded unprotected sex. CONCLUSIONS: STI/HIV testing must be viewed as one strategy within a package of possible risk reduction. For those in choice-restricted relationships, clinicians should screen patients for partner abuse and provide additional support and referrals as clinically appropriate.
