RESUMO

BACKGROUND: Little is known about penile high-risk HPV among MSM in low-and-middle income countries. We aimed to determine the incidence, clearance and persistence of penile hrHPV among Rwandan MSM. METHODS: We enrolled 350 MSM (345 with valid HPV results), aged ≥18 years, at each visit (6-12 months apart), we collected penile PreservCyt specimens and blood for HPV and HIV testing, socio-demographic and behavioral variables. HPV testing was performed using the Ampfire assay. Penile hrHPV incidence and clearance/1,000 person-months of follow-up (PMF), prevalent- and incident-persistence were computed and compared by HIV status. RESULTS: The mean age was 27.7 ± 6.7 years and 19.4% were living with HIV. Penile hrHPV incidence was 34.8 (95% CI: 29.1, 41.8)/1,000 PMF. HPV16 (11.7, CI 9.26, 14.9) and HPV59 (6.1, CI 4.52, 8.39) had the highest incidence rates. Prevalent- and incident-persistence were 47.5% and 46.6%, respectively. HPV66 (33.3%), HPV52 (30.8%) and HPV16 (29.2%) had the highest prevalent-persistence and HPV33 (53.8%), HPV31 (46.7%) and HPV16 (42.6%) the highest incident-persistence. No differences were found by HIV status except for HPV45 (higher in MSM with HIV). CONCLUSION: We found high incidence and prevalent/incident-persistence of penile hrHPV among Rwandan MSM. This highlights the importance of preventive strategies for HPV-associated anogenital cancers.

RESUMO

Comorbid depression and heavy episodic drinking (HED) may threaten the success of "treat all" policies in sub-Saharan Africa as the population of people with HIV (PWH) ages. We investigated associations between depressive symptoms and heavy episodic drinking (HED) and the extent the relationship differed across ages among PWH receiving HIV care in Cameroon. We conducted a retrospective analysis of 18-60-year-old PWH on antiretroviral therapy in Cameroon from January 2016 to March 2020. Age-varying effect modelling was conducted to assess associations between depressive symptoms and HED across ages and by gender. Prevalence of depression and HED was highest at ages 20 and 25, respectively. After age 25, the magnitude of the association between depressive symptoms and HED was significant and increased until age 30 (aOR: 1.88, 95% CI: 1.48, 2.39), with associations remaining significant until age 55 (aOR: 1.64, 95% CI: 1.17, 2.29). Women had more variability and higher magnitudes of associations between depressive symptoms and HED than men. The interrelationship between depressive symptoms and HED was significant throughout most of adulthood for PWH receiving HIV care in Cameroon. Understanding age and gender trends in these associations can guide integration efforts in HIV care settings.

RESUMO

This study qualitatively explores HIV-related gossip as both a manifestation and driver of HIV-related stigma, which is a known barrier to HIV testing and treatment in Botswana. Data were elicited from 5 focus group discussions and 46 semi-structured in-depth interviews with individuals living with HIV and community members with undisclosed serostatus in Gaborone, Botswana in 2017 (n = 84). Directed content analysis using the 'What Matters Most' theoretical framework identified culturally salient manifestations of HIV-related stigma; simultaneous use of Modified Labeling Theory allowed interpretation and stepwise organization of how the social phenomenon of gossip leads to adverse HIV outcomes. Results indicated that HIV-related gossip can diminish community standing through culturally influenced mechanisms, in turn precipitating poor psychosocial well-being and worsened HIV-related outcomes. These harms may be offset by protective factors, such as appearing healthy, accepting one's HIV status, and community education about the harms of gossip.

RESUMO

Food insecurity disproportionately affects people with HIV and women in the United States (US). More evidence is needed to understand the interplay between levels of food insecurity and levels of antiretroviral therapy (ART) adherence over time, as well as how food insecurity relates to engagement in HIV care. We used random effects models with longitudinal data from the US Women's Interagency HIV Study to estimate the (1) adjusted associations of current and 6-month lagged food security with ART adherence categories (n = 1646), and (2) adjusted associations of food security with engagement-in-care (n = 1733). Very low food security was associated with a higher relative risk of ART non-adherence at prior and current visits compared with food security, and this association increased across non-adherence categories. Very low food security was associated with lower odds of receiving HIV care and higher odds of a missed visit. Food insecurity among US women with HIV is associated with poorer engagement in care and degree of ART non-adherence over time.

RESUMO

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.

RESUMO

BACKGROUND: 'Treat All' policies recommending immediate antiretroviral therapy (ART) soon after HIV diagnosis for all people living with HIV (PLHIV) are now ubiquitous in sub-Saharan Africa. While early ART initiation and retention is effective at curtailing disease progression and transmission, evidence suggests that stigma may act as a barrier to engagement in care. This study sought to understand the relationships between HIV stigma and engagement in care for PLHIV in Rwanda in the context of Treat All. METHODS: Between September 2018 and March 2019, we conducted semi-structured, qualitative interviews with adult PLHIV receiving care at two health centers in Kigali, Rwanda. We used a grounded theory approach to data analysis to develop conceptual framework describing how stigma influences HIV care engagement in the context of early Treat All policy implementation in Rwanda. RESULTS: Among 37 participants, 27 (73%) were women and the median age was 31 years. Participants described how care engagement under Treat All, including taking medications and attending appointments, increased their visibility as PLHIV. This served to normalize HIV and use of ART but also led to high levels of anticipated stigma in the health center and community at early stages of treatment. Enacted stigma from family and community members and resultant internalized stigma acted as additional barriers to care engagement. Nonetheless, participants described how psychosocial support from care providers and family members helped them cope with stigma and promoted continued engagement in care. CONCLUSIONS: Treat All policy in Rwanda has heightened the visibility of HIV at the individual and social levels, which has influenced HIV stigma, normalization, psychosocial support and care engagement in complex ways. Leveraging the individual and community support described by PLHIV to deliver evidence-based, peer or provider-delivered stigma reduction interventions may aid in attaining Treat All goals.

RESUMO

BACKGROUND: Although 1·3 million women with HIV give birth annually, care and outcomes for HIV-exposed infants remain incompletely understood. We analyzed programmatic and health indicators in a large, multidecade global dataset of linked mother-infant records from clinics and programs associated with the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. METHODS AND FINDINGS: HIV-exposed infants were eligible for this retrospective cohort analysis if enrolled at <18 months at 198 clinics in 10 countries across 5 IeDEA regions: East Africa (EA), Central Africa (CA), West Africa (WA), Southern Africa (SA), and the Caribbean, Central, and South America network (CCASAnet). We estimated cumulative incidences of DNA PCR testing, loss to follow-up (LTFU), HIV diagnosis, and death through 24 months of age using proportional subdistribution hazard models accounting for competing risks. Competing risks were transfer, care withdrawal, and confirmation of negative HIV status, along with LTFU and death, when not the outcome of interest. In CA and EA, we quantified associations between maternal/infant characteristics and each outcome. A total of 82,067 infants (47,300 EA, 10,699 CA, 6,503 WA, 15,770 SA, 1,795 CCASAnet) born from 1997 to 2021 were included. Maternal antiretroviral therapy (ART) use during pregnancy ranged from 65·6% (CCASAnet) to 89·5% (EA), with improvements in all regions over time. Twenty-four-month cumulative incidences varied widely across regions, ranging from 12·3% (95% confidence limit [CL], 11·2%,13·5%) in WA to 94·8% (95% CL, 94·6%,95·1%) in EA for DNA PCR testing; 56·2% (95% CL, 55·2%,57·1%) in EA to 98·5% (95% CL, 98·3%,98·7%) in WA for LTFU; 1·9% (95% CL, 1·6%,2·3%) in WA to 10·3% (95% CL, 9·7%,10·9%) in EA for HIV diagnosis; and 0·5% (95% CL, 0·2%,1·0%) in CCASAnet to 4·7% (95% CL, 4·4%,5·0%) in EA for death. Although infant retention did not improve, HIV diagnosis and death decreased over time, and in EA, the cumulative incidence of HIV diagnosis decreased substantially, declining to 2·9% (95% CL, 1·5%,5·4%) in 2020. Maternal ART was associated with decreased infant mortality (subdistribution hazard ratio [sdHR], 0·65; 95% CL, 0·47,0·91 in EA, and sdHR, 0·51; 95% CL, 0·36,0·74 in CA) and HIV diagnosis (sdHR, 0·40; 95% CL, 0·31,0·50 in EA, and sdHR, 0·41; 95% CL, 0·31,0·54 in CA). Study limitations include potential misclassification of outcomes in real-world service delivery data and possible nonrepresentativeness of IeDEA sites and the population of HIV-exposed infants they serve. CONCLUSIONS: While there was marked regional and temporal heterogeneity in clinical and programmatic outcomes, infant LTFU was high across all regions and time periods. Further efforts are needed to keep HIV-exposed infants in care to receive essential services to reduce HIV infection and mortality.

RESUMO

Depression is associated with suboptimal HIV care outcomes. Little is known about the extent to which the prevalence of depressive symptoms varies across the HIV care continuum. Also, the relationship among gender, HIV disclosure, HIV care stage, and depressive symptoms in PLWH remains poorly understood. We analyzed cross-sectional data from 12,507 PLWH at enrollment in International epidemiology Databases to Evaluate AIDS (IeDEA) Cameroon between 2016 and 2020. Recent depressive symptoms were assessed using the Patient Health Questionnaire-2 (PHQ-2). A score of three or greater on the PHQ-2 was considered indicative of likely major depressive disorder. We estimated the prevalence of depressive symptoms across three stages of HIV care: those not yet on antiretroviral therapy (ART), recent ART initiators (ART initiation ≤ 30 days prior), and ART users (ART initiation > 30 days prior). Adjusted prevalence differences (aPD) of depressive symptoms were estimated comparing recent ART initiators and ART users. Disclosure and gender were examined as effect measure modifiers of the relationship between HIV care stage and depressive symptoms. The prevalence of depressive symptoms was 11.9%, 22.0%, and 8.7% among PLWH not yet on ART, recent ART initiators, and ART users, respectively. ART users had significantly lower prevalence of depressive symptoms compared to recent ART initiators (aPD - 0.09 [95% CI - 0.11, - 0.08]). Neither gender nor HIV disclosure modified the effect measure of the relationship between HIV care stage and depressive symptoms. Depressive symptoms were commonly reported among this group of PLWH and were associated with recent ART initiation. Integration of screening and treatment of depression into HIV care should be prioritized and may be particularly relevant for PLWH initiating ART.

RESUMO

Social support is associated with improved HIV care and quality of life. We utilized latent class analysis to identify three classes of baseline emotional and tangible perceived social support, termed "Strong", "Wavering" and "Weak". "Weak" vs. "Strong" perceived social support was associated over time with an 8% decreased risk of optimal antiretroviral therapy (ART) adherence for emotional and 6% decreased risk for tangible perceived social support. Importantly, "Wavering" vs "Strong" social support also showed a decreased risk of ART adherence of 6% for emotional and 3% for tangible support. "Strong" vs. "Weak" perceived support had a similar association with undetectable viral load, but the association for "Strong" vs. "Wavering" support was not statistically significant. Intensity of social support is associated with HIV care outcomes, and strong social support may be needed for some individuals. It is important to quantify the level or intensity of social support that is needed to optimize HIV outcomes.


RESUMEN: El apoyo social está asociado con una mejor atención y calidad de vida del virus de inmunodeficiencia humana (VIH). Utilizamos el análisis de clase latente para identificar tres clases de apoyo social percibido emocional y tangible de referencia, denominado "fuerte", "vacilante" y "débil". El apoyo social percibido "débil" versus el "fuerte" se asoció con el tiempo con una disminución del 8% en el riesgo de una adherencia óptima al terapia antirretroviral (TAR) para el apoyo emocional y del 6% en el riesgo de un apoyo social percibido tangible. Es importante destacar que el apoyo social "vacilante" frente a "fuerte" también mostró una disminución del riesgo de adherencia al TAR del 6% para el apoyo emocional y del 3% para el apoyo tangible. El apoyo percibido "fuerte" frente a "débil" tuvo una asociación similar con una carga viral indetectable, pero la asociación entre el apoyo "fuerte" y el apoyo "vacilante" no fue estadísticamente significativa. La intensidad del apoyo social está asociada con los resultados de la atención del VIH, y algunas personas pueden necesitar un fuerte apoyo social. Es importante cuantificar el nivel o la intensidad del apoyo social que se necesita para optimizar los resultados del VIH.

RESUMO

BACKGROUND: Food insecurity is associated with increased morbidity and mortality in people with human immunodeficiency virus (HIV) on antiretroviral therapy, but its relationship with immune dysregulation, a hallmark of HIV infection and comorbidity, is unknown. METHODS: In 241 women participating in the Women's Interagency HIV Study, peripheral blood mononuclear cells were characterized by flow cytometry to identify cell subsets, comprising surface markers of activation (%CD38+HLADR+), senescence (%CD57+CD28-), exhaustion (%PD-1+), and co-stimulation (%CD57- CD28+) on CD4+ and CD8+ T cells. Mixed-effects linear regression models were used to assess the relationships of food insecurity with immune outcomes, accounting for repeated measures at ≤3 study visits and adjusting for sociodemographic and clinical factors. RESULTS: At the baseline study visit, 71% of participants identified as non-Hispanic Black, 75% were virally suppressed, and 43% experienced food insecurity. Food insecurity was associated with increased activation of CD4+ and CD8+ T cells, increased senescence of CD8+ T cells, and decreased co-stimulation of CD4+ and CD8+ T cells (all P < .05), adjusting for age, race/ethnicity, income, education, substance use, smoking, HIV viral load, and CD4 count. In stratified analyses, the association of food insecurity with CD4+ T-cell activation was more pronounced in women with uncontrolled HIV (viral load >40 copies/mL and CD4 <500 cells/mm3) but remained statistically significant in those with controlled HIV. CONCLUSIONS: Food insecurity may contribute to the persistent immune activation and senescence in women with HIV on antiretroviral therapy, independently of HIV control. Reducing food insecurity may be important for decreasing non-AIDS-related disease risk in this population.

RESUMO

In 2019, the National Institutes of Health combined the Multicenter AIDS Cohort Study (MACS) and the Women's Interagency HIV Study (WIHS) into the MACS/WIHS Combined Cohort Study (MWCCS). In this paper, participants who made a study visit during October 2018-September 2019 (targeted for MWCCS enrollment) are described by human immunodeficiency virus (HIV) serostatus and compared with people living with HIV (PLWH) in the United States. Participants include 2,115 women and 1,901 men with a median age of 56 years (interquartile range, 48-63); 62% are PLWH. Study sites encompass the South (18%), the Mid-Atlantic/Northeast (45%), the West Coast (22%), and the Midwest (15%). Participant race/ethnicity approximates that of PLWH throughout the United States. Longitudinal data and specimens collected for 35 years (men) and 25 years (women) were combined. Differences in data collection and coding were reviewed, and key risk factor and comorbidity data were harmonized. For example, recent use of alcohol (62%) and tobacco (28%) are common, as are dyslipidemia (64%), hypertension (56%), obesity (42%), mildly or severely impaired daily activities (31%), depressive symptoms (28%), and diabetes (22%). The MWCCS repository includes serum, plasma, peripheral blood mononuclear cells, cell pellets, urine, cervicovaginal lavage samples, oral samples, B-cell lines, stool, and semen specimens. Demographic differences between the MACS and WIHS can confound analyses by sex. The merged MWCCS is both an ongoing observational cohort study and a valuable resource for harmonized longitudinal data and specimens for HIV-related research.

RESUMO

BACKGROUND: Cervical cancer is a leading cause of death among Cameroon women. The burden of cervical cancer is in part traceable to the inadequate understanding of socio-contextual determinants of access to screening and prevention opportunities. We explored multilevel individual, community and structural factors that facilitate or inhibit cervical cancer prevention in women at risk in a low-income, high HIV prevalence context. METHODS: We utilized an exploratory qualitative approach to obtain data through focus group discussions and in-depth interviews from May to August, 2018. A two-stage purposive sampling strategy was used to select 80 women and 20 men who participated in 8 focus group discussions and 8 in-depth interviews. The socio-ecological model guided data analyses to identify micro-, meso-, and macro-level determinants of cervical cancer screening. RESULTS: Micro-level factors including lack of awareness and knowledge about cervical cancer, lack of access to information, excessive cost of cervical cancer screening, low risk perceptions, and poor health seeking behaviors were major barriers for women seeking cervical cancer screening. Meso-level factors, such as social networks, socio-cultural norms, perceptions of the role of men and HIV-related stigma when screening is integrated into HIV care, also engender negative attitudes and behaviors. Macro-level barriers to cervical cancer screening included poorly equipped health facilities and a lack of national cancer prevention policies and programs. CONCLUSION: In the context of the call for elimination of cervical cancer as a public health problem, our findings highlight challenges and opportunities that should be considered when implementing interventions to increase uptake of cervical cancer screening in low-middle income settings.

RESUMO

BACKGROUND: Food insecurity is a well-established determinant of suboptimal, self-reported antiretroviral therapy (ART) adherence, but few studies have investigated this association using objective adherence measures. We examined the association of food insecurity with levels of ART concentrations in hair among women living with human immunodeficiency virus (WLHIV) in the United States. METHODS: We analyzed longitudinal data collected semiannually from 2013 through 2015 from the Women's Interagency HIV Study, a multisite, prospective, cohort study of WLHIV and controls not living with HIV. Our sample comprised 1944 person-visits from 677 WLHIV. Food insecurity was measured using the US Household Food Security Survey Module. ART concentrations in hair, an objective and validated measure of drug adherence and exposure, were measured using high-performance liquid chromatography with mass spectrometry detection for regimens that included darunavir, atazanavir, raltegravir, or dolutegravir. We conducted multiple 3-level linear regressions that accounted for repeated measures and the ART medication(s) taken at each visit, adjusting for sociodemographic and clinical characteristics. RESULTS: At baseline, 67% of participants were virally suppressed and 35% reported food insecurity. In the base multivariable model, each 3-point increase in food insecurity was associated with 0.94-fold lower ART concentration in hair (95% confidence interval, 0.89 to 0.99). This effect remained unchanged after adjusting for self-reported adherence. CONCLUSIONS: Food insecurity was associated with lower ART concentrations in hair, suggesting that food insecurity may be associated with suboptimal ART adherence and/or drug absorption. Interventions seeking to improve ART adherence among WLHIV should consider and address the role of food insecurity.

RESUMO

BACKGROUND: In some time-to-event analyses, it is unclear whether loss to follow up should be treated as a censoring event or competing event. Such ambiguity is particularly common in HIV research that uses routinely collected clinical data to report the timing of key milestones along the HIV care continuum. In this setting, loss to follow up may be viewed as a censoring event, under the assumption that patients who are "lost" from a study clinic immediately enroll in care elsewhere, or a competing event, under the assumption that people "lost" are out of care all together. METHODS: We illustrate an approach to address this ambiguity when estimating the 2-year risk of antiretroviral treatment initiation among 19,506 people living with HIV who enrolled in the IeDEA Central Africa cohort between 2006 and 2017, along with published estimates from tracing studies in Africa. We also assessed the finite sample properties of the proposed approach using simulation experiments. RESULTS: The estimated 2-year risk of treatment initiation was 69% if patients were censored at loss to follow up or 59% if losses to follow up were treated as competing events. Using the proposed approach, we estimated that the 2-year risk of antiretroviral therapy initiation was 62% (95% confidence interval: 61, 62). The proposed approach had little bias and appropriate confidence interval coverage under scenarios examined in the simulation experiments. CONCLUSIONS: The proposed approach relaxes the assumptions inherent in treating loss to follow up as a censoring or competing event in clinical HIV cohort studies.

RESUMO

Objectives. To examine whether women's incarceration increases numbers of total and new sexual partners.Methods. US women with or at risk for HIV in a multicenter cohort study answered incarceration and sexual partner questions semiannually between 2007 and 2017. We used marginal structural models to compare total and new partners at visits not following incarceration with all visits following incarceration and visits immediately following incarceration. Covariates included demographics, HIV status, sex exchange, drug or alcohol use, and housing instability.Results. Of the 3180 participants, 155 were incarcerated. Women reported 2 partners, 3 or more partners, and new partners at 5.2%, 5.2%, and 9.3% of visits, respectively. Relative to visits not occurring after incarceration, odds ratios were 2.41 (95% confidence interval [CI] = 1.20, 4.85) for 2 partners, 2.03 (95% CI = 0.97, 4.26) for 3 or more partners, and 3.24 (95% CI = 1.69, 6.22) for new partners at visits immediately after incarceration. Odds ratios were similar for all visits following incarceration.Conclusions. Women had more total partners and new partners immediately and at all visits following incarceration after confounders and loss to follow-up had been taken into account.

RESUMO

Identifying structural determinants affecting HIV outcomes is important for informing interventions across heterogeneous geographies. Longitudinal hierarchical generalized mixed-effects models were used to quantify the associations between changes in certain structural-level factors on HIV care engagement, medication adherence, and viral suppression. Among women living with HIV in the WIHS, ten-unit increases in census-tract level proportions of unemployment, poverty, and lack of car ownership were inversely associated with viral suppression and medication adherence, while educational attainment and owner-occupied housing were positively associated with both outcomes. Notably, increased residential stability (aOR 5.68, 95% CI 2.93, 9.04) was positively associated with HIV care engagement, as were unemployment (aOR: 1.59, 95% CI 1.57, 1.60), lack of car ownership (aOR 1.14, 95% CI 1.13, 1.15), and female-headed households (aOR 1.23, 95% CI 1.22, 1.23). This underscores the importance of understanding neighborhood context, including factors that may not always be considered influential, in achieving optimal HIV-related outcomes.

RESUMO

Background: Chronic inflammation is associated with AIDS-defining and non-AIDS-defining conditions. Limited research has considered how food insecurity influences chronic inflammation among people living with human immunodeficiency virus (HIV). We examined whether food insecurity was associated with higher levels of inflammation among women living with HIV (WWH) in the United States. Methods: We analyzed cross-sectional data collected in 2015 from 421 participants on antiretroviral therapy from the Women's Interagency HIV Study. The exposure was any food insecurity. The outcome was inflammation, measured by proinflammatory cytokine interleukin-6 (IL-6) and tumor necroses factor receptor 1 (TNFR1) levels. We conducted multivariable linear regressions, adjusting for sociodemographic, clinical, and nutritional factors. Results: Nearly one-third of participants (31%) were food insecure and 79% were virally suppressed (<20 copies/mL). In adjusted analyses, food insecurity was associated with 1.23 times the level of IL-6 (95% confidence interval [CI], 1.06-1.44) and 1.13 times the level of TNFR1 (95% CI, 1.05-1.21). Findings did not differ by HIV control (virally suppressed with CD4 counts ≥500 cells/mm3 or not) in adjusted stratified analyses. Conclusion: Food insecurity was associated with elevated inflammation among WWH regardless of HIV control. Findings support the need for programs that address food insecurity among WWH.

RESUMO

BACKGROUND: Food insecurity, which disproportionately affects marginalized women in the United States, is associated with depressive symptoms. Few studies have examined relations of food insecurity with other mental health outcomes. OBJECTIVE: The aim of this study was to investigate the associations of food insecurity with symptoms of generalized anxiety disorder (GAD), stress, and posttraumatic stress disorder (PTSD) in the Women's Interagency HIV Study (WIHS), a prospective cohort study of women with or at risk of HIV in the United States. METHODS: Participants were 2553 women with or at risk of HIV, predominantly African American/black (71.6%). Structured questionnaires were conducted during April 2013-March 2016 every 6 mo. Food security (FS) was the primary predictor, measured using the Household Food Security Survey Module. We measured longitudinal outcomes for GAD (GAD-7 score and a binary GAD-7 screener for moderate-to-severe GAD). Only cross-sectional data were available for outcomes measuring perceived stress (PSS-10 score) and PTSD (PCL-C score and a binary PCL-C screener for PTSD). We examined associations of FS with the outcomes through use of multivariable linear and logistic regression, including lagged associations with GAD outcomes. RESULTS: After adjusting for sociodemographic and health-related factors including HIV serostatus, current marginal, low, and very low FS were associated with increasingly higher GAD-7 scores, and with 1.41 (95% CI: 1.10, 1.80; P < 0.01), 2.03 (95% CI: 1.59, 2.61; P < 0.001), and 3.23 (95% CI: 2.43, 4.29; P < 0.001) times higher odds of screening positive for moderate-to-severe GAD, respectively. Low and very low FS at the previous visit (6 mo earlier) were independently associated with GAD outcomes at current visit. Associations of FS with PSS-10 and PCL-C scores exhibited similar dose-response relations. Very low FS was associated with 1.93 (95% CI: 1.15, 3.24; P < 0.05) times higher odds of screening positive for PTSD. CONCLUSIONS: Food insecurity may be associated with a range of poor mental health outcomes among women in the United States with or at risk of HIV.

RESUMO

BACKGROUND: Food insecurity and mental health negatively affect the lives of women in the United States. Participants in the Women's Interagency HIV Study (WIHS) provided the opportunity to understand the association of food insecurity with depression and mental well-being over time. OBJECTIVE: We investigated the association between current and persistent food insecurity and depression among women at risk of or living with HIV in the United States. METHODS: We used longitudinal data from the WIHS, a prospective cohort study in women at risk of or living with HIV from multiple sites in the United States. Participants completed 6 semiannual assessments from 2013 to 2016 on food security (FS; high, marginal, low, and very low) and mental health (i.e., depressive symptoms and mental well-being). We used multiple regression analysis to estimate the association between these variables. RESULTS: Among 2551 participants, 44% were food insecure and 35% reported depressive symptoms indicative of probable depression. Current marginal, low, and very low FS were associated with 2.1-, 3.5-, and 5.5-point (all P < 0.001) higher depression scores, respectively. In models adjusting for both current and previous FS, previous marginal, low, and very low FS were associated with 0.2-, 0.93-, and 1.52-point higher scores, respectively (all P < 0.001). Women with very low FS at both time points (persistent food insecurity) had a 6.86-point higher depression score (P < 0.001). In the mental health models, there was a dose-response relation between current FS and worse mental health even when controlling for previous FS (all P < 0.001). Previous low FS was associated with worse mental health. These associations did not differ by HIV status. CONCLUSIONS: Food insecurity placed women at risk of depression and poor mental well-being, but the risk was substantially higher for women experiencing persistent food insecurity. Future interventions to improve women's mental health call for multilevel components that include addressing food insecurity.

RESUMO

Social support is associated with HIV-related health outcomes. However, few studies have explored this longitudinally. We assessed psychometric properties of the Medical Outcomes Study's Social Support Survey among women in the Women's Interagency HIV Study, and explored the longitudinal effects of social support on HIV medication adherence (HIV-positive women) and healthcare utilization (HIV-positive and negative women). The 15 questions loaded into two factors, with Cronbach's Alpha > 0.95. Over 3 years, perceived emotional support was associated with optimal medication adherence (OR 1.19, 95% CI 1.10-1.28) and healthcare utilization (OR 1.16, 95% CI 1.05-1.27), and tangible social support with adherence only (OR 1.18, 95% CI 1.08-1.27) when controlling for covariates, including core sociodemographic characteristics and depressive symptoms. Interventions to further understand the drivers of sub-types of social support as well as enhance sustained social support may assist with optimizing care of women with and at risk for HIV.
