INTRODUCTION: HIV prevalence among criminal justice (CJ)-involved adults is five times higher than the general population. Following incarceration, CJ-involved individuals experience multilevel barriers to HIV prevention. Pre-exposure prophylaxis (PrEP) is a widely available, daily medication efficacious in preventing HIV. Little is known about PrEP knowledge, acceptability, initiation and sustained use among CJ-involved persons or about how these outcomes vary by multilevel factors. The Southern Pre-Exposure Prophylaxis Study (SPECS) will investigate barriers and facilitators for PrEP initiation and sustained use among CJ-involved adults, building a foundation for PrEP interventions for this underserved population.
METHODS AND ANALYSIS: SPECS uses a mixed-methods sequential …
Developing Triage Tools For Retention In Care And Viral Suppression, And Identifying Predictors Of Sexually Transmitted Infections Among People With Hiv, Merhawi T. Gebrezgi
Developing Triage Tools For Retention In Care And Viral Suppression, And Identifying Predictors Of Sexually Transmitted Infections Among People With Hiv, Merhawi T. Gebrezgi
FIU Electronic Theses and Dissertations
This study developed risk prediction tools for non-retention in HIV care and non-viral suppression, and identified factors associated with self-reported chlamydia and gonorrhea diagnosis among people with HIV (PHIV) in the Miami-Dade County Ryan White Program (RWP). Using retrospective cohort study data, we used stepwise logistic regression to develop score-based risk prediction tools for non-retention in care and non-viral suppression. We then used bootstrapping to internally validate the risk prediction tools. We also assessed the prevalence of self-reported chlamydia and gonorrhea diagnoses and factors associated with the diagnoses cross-sectionally using multivariate logistic regression.
Among the 7439 people meeting the inclusion …
Trinidad & Tobago : Hiv Epidemic, Madison Caldwell
Trinidad & Tobago : Hiv Epidemic, Madison Caldwell
Global Public Health
Trinidad and Tobago are twin islands located in the Caribbean off the coast of Venezuela. In the recent years since about 1990, citizens of this country have been greatly affected by the HIV epidemic. HIV stands for human immunodeficiency virus and is spread through infected seman, blood, or vaginal fluids usually through sexual intercourse. As this virus continues to progress in the body, it will eventually turn into AIDS, which stands for acquired immunodeficiency syndrome. Once HIV progresses to AIDS, the outcome is ultimately fatal, hence why there is a dire need to promote awareness and methods of intervention to …
Hiv And Concurrent Sexual Partnerships: Modelling The Role Of Coital Dilution, Larry Sawers, Alan G. Isaac, Eileen Stillwaggon
Hiv And Concurrent Sexual Partnerships: Modelling The Role Of Coital Dilution, Larry Sawers, Alan G. Isaac, Eileen Stillwaggon
Economics Faculty Publications
Background: The concurrency hypothesis asserts that high prevalence of overlapping sexual partnerships explains extraordinarily high HIV levels in sub-Saharan Africa. Earlier simulation models show that the network effect of concurrency can increase HIV incidence, but those models do not account for the coital dilution effect (nonprimary partnerships have lower coital frequency than primary partnerships).
Methods: We modify the model of Eaton et al (AIDS and Behavior, September 2010) to incorporate coital dilution by assigning lower coital frequencies to non-primary partnerships. We parameterize coital dilution based on the empirical work of Morris et al (PLoS ONE, December …
Concurrent Sexual Partnerships Do Not Explain The Hiv Epidemics In Africa: A Systematic Review Of The Evidence, Larry Sawers, Eileen Stillwaggon
Concurrent Sexual Partnerships Do Not Explain The Hiv Epidemics In Africa: A Systematic Review Of The Evidence, Larry Sawers, Eileen Stillwaggon

The notion that concurrent sexual partnerships are especially common in sub-Saharan Africa and explain the region’s high HIV prevalence is accepted by many as conventional wisdom. In this paper, we evaluate the quantitative and qualitative evidence offered by the principal proponents of the concurrency hypothesis and analyze the mathematical model they use to establish the plausibility of the hypothesis.
We find that research seeking to establish a statistical correlation between concurrency and HIV prevalence either finds no correlation or has important limitations. Furthermore, in order to simulate rapid spread of HIV, mathematical models require unrealistic assumptions about frequency of sexual …
Complexity, Cofactors, And The Failure Of Aids Policy In Africa, Eileen Stillwaggon
Complexity, Cofactors, And The Failure Of Aids Policy In Africa, Eileen Stillwaggon
Economics Faculty Publications
Global AIDS policy still treats HIV as an exceptional case, abstracting from the context in which infection occurs. Policy is based on a simplistic theory of HIV causation, and evaluated using outdated tools of health economics. Recent calls for a health systems strategy – preventing and treating HIV within a programme of comprehensive health care – have not yet influenced the silo approach of AIDS policy.
Evidence continues to accumulate, showing that multiple factors, such as malnutrition, malaria and helminthes, increase the risk of sexual and vertical transmission of HIV. Moreover, complementary interventions that reduce viral load, improve immune response, …

OBJECTIVES: This study examines the impact of the condom availability program in New York City public high schools by comparing rates of sexual activity and condom use for New York students and similar students in Chicago.
METHODS: A total of 7119 students from 12 randomly selected New York schools and 5738 students from 10 Chicago schools participated in a cross-sectional survey.
RESULTS: New York students, compared with Chicago students, reported equal rates of sexual activity but higher rates of condom use at last intercourse (odds ratio [OR] = 1.36). For higher-risk students (those with three or more sexual partners in …
