Two modeling approaches are commonly used to estimate the associations between neighborhood characteristics and individual-level health outcomes in multilevel studies (subjects within neighborhoods). Random effects models (or mixed models) use maximum likelihood estimation. Population average typically a generalized estimating equation (GEE) approach. These methods place of basic regression because residents same may be correlated, thus violating independence assumptions made by traditional...
Afghanistan and Iraq veterans experienced traumas during deployment, disrupted connections with friends family. In this context, it is critical to understand the nature of veterans' transition civilian life, challenges navigated, approaches reconnection. We investigated these issues in a qualitative study, framed by homecoming theory, that comprised in-depth interviews 24 veterans. Using an inductive thematic analysis approach, we developed three overarching themes. Military as family...
Stigma is a known barrier to HIV testing and care. Because access antiretroviral therapy reduces overt illness mortality, some scholars theorized that HIV-related stigma would decrease as treatment availability increased. However, the association between ART accessibility has not been straightforward originally predicted. We conducted "situational analysis"—a rapid, community-based qualitative assessment inform combination prevention program in high prevalence communities. In context of this...
South African men who have sex with (MSM) a high burden of undiagnosed HIV infection and HIV-testing rates incommensurate their risk. self-testing (HIVST) may increase testing uptake, frequency, earlier detection treatment.Gert Sibande Ehlanzeni districts, Mpumalanga Province, Africa.We conducted longitudinal HIVST study among MSM between June 2015 May 2017. Overall 127 HIV-negative were provided up to 9 test kits choice-oral fluid or blood fingerstick-to use themselves distribute networks....
Men who have sex with men (MSM) continue to be disproportionately impacted globally by the HIV epidemic. Studies suggest that self-testing (HIVST) is highly acceptable among MSM. Social network strategies increase testing are effective in reaching MSM, particularly MSM of color, may not otherwise test. We tested a social network-based strategy distribute HIVST kits African American (AAMSM) and Latino (LMSM).This study was conducted Alameda County, California, large, urban/suburban county an...
BackgroundHIV testing rates in many hyper-endemic areas are lower than needed to curtail the HIV epidemic. New strategies overcome barriers traditional clinic based testing; self-testing is one modality that offers promise reaching individuals who experience clinic-based testing.MethodsWe conducted a randomized control trial among young women ages 18-26 living rural Mpumalanga, South Africa where they were 1:1 allocation either the: (1) Counseling and Testing (HCT) arm: an invitation test at...
We sought to determine the association of social-environmental factors with condom use and sexually transmitted infections (STIs) among 420 sex workers participating in an STI/HIV prevention study Corumbá, Brazil, inform future intervention efforts.
IntroductionCommunity mobilizing strategies are essential to health promotion and uptake of HIV prevention. However, there has been little conceptual work conducted establish the core components community mobilization, which needed guide prevention programming evaluation. ObjectivesWe aimed identify key domains mobilization (CM) change outcomes or behaviors, determine whether these hypothesized CM were relevant a rural South African setting. MethodWe studied social movements capacity,...
HIV self-testing has the potential to increase testing frequency and uptake. This pilot study assessed feasibility acceptability of in a sample sexually active men who have sex with (MSM) Peru Brazil. Participants were trained use whole blood rapid self-test instructed monthly during this three-month study. Test was measured self-reported test at one-month visits, by direct observation administration final visit. A total 103 participants (52 51 Brazil) enrolled, 86% completed Nearly all...
A self-administered, street intercept survey was conducted in order to examine the relation of stigma and shame associated with sexually transmitted infections (STI) STI testing practices, partner notification, partner-delivered treatment among young African American men (n=108) a low-income, urban community San Francisco high burden. Multivariate logistic regression revealed that increasing STI-related significantly decreased odds testing, such every standard deviation increase score 0.62...
Community mobilization (CM) is increasingly recognized as critical to generating changes in social norms and behaviours needed achieve reductions HIV. We conducted a CM intervention modify negative gender norms, particularly among men, order reduce associated HIV risk.Twenty two villages the Agincourt Health Socio-Demographic Surveillance Site rural Mpumalanga, South Africa were randomized either theory-based, transformative, or no intervention. Two cross-sectional, population-based surveys...
The uptake of HIV self-testing (HIVST) could address socio-structural barriers that prevent South African youth from utilizing the testing resources available in their communities. However, to facilitate this, we must tailor components HIVST kit and process ensure reach encourage test. purpose this study elucidate concerns issues regarding rollout among youth. This was conducted two phases: 1) focus group discussions with rural, aged 18–24 2) direct observations participants completing an...
This paper examines the reporting of sexual and other risk behaviors within a randomized experiment using computerized versus face-to-face interview mode. Biomarkers for sexually transmitted infection (STI) were used to validate self-reported behavior by As part parent study evaluating home clinic screening diagnosis STIs, 818 women aged 18-40 years recruited in 2004 at or near primary care São Paulo, Brazil, audio computer-assisted self-interviewing. Ninety-six percent participants tested...
Sexually transmitted infection (STI)/HIV prevention programs, which do not modify social structural contexts that contribute to risk of STI/HIV may fail bring about improvements in health, particularly among groups who experience discrimination and exclusion from public life. We conducted a multilevel intervention with sex workers, including improved clinical care community-mobilizing strategies factors shape sexual behavior, improve condom use reduce incident STI.We followed 420 workers...
