Decreasing HIV transmissions to African American women through interventions for men living with HIV post-incarceration: An agent-based modeling study

Background

Incarceration and HIV disproportionately impact African American communities. The mass incarceration of African American men is hypothesized to increase HIV acquisition risk for African American women. Interventions optimizing HIV care engagement and minimizing sexual risk behaviors for men living with HIV post-incarceration may decrease HIV incidence.

Methods

Using an agent-based model, we simulated a sexual and injection drug using network representing the African American population of Philadelphia. We compared intervention strategies for men living with HIV post-incarceration by the number of averted HIV transmissions to women within the community. Three interventions were evaluated: a 90-90-90 scenario scaling up HIV testing, ART provision, and ART adherence; a behavioral intervention decreasing sexual risk behaviors; and a combination intervention involving both.

Results

The status quo scenario projected 2,836 HIV transmissions to women over twenty years. HIV transmissions to women decreased by 29% with the 90-90-90 intervention, 23% with the behavioral intervention, and 37% with both. The number of men living with HIV receiving the intervention needed in order to prevent a single HIV transmission ranged between 6 and 10.

Conclusion

Interventions to improve care engagement and decrease sexual risk behaviors post-incarceration for men living with HIV have the potential to decrease HIV incidence within African American heterosexual networks.

Potential drivers of HIV acquisition in African-American women related to mass incarceration: an agent-based modelling study

Background

The United States has the highest incarceration rate in the world. Incarceration can increase HIV risk behaviors for individuals involved with the criminal justice system and may be a driver of HIV acquisition within the community.

Methods

We used an agent-based model to simulate HIV transmission in a sexual-contact network representing heterosexual African American men and women in Philadelphia to identify factors influencing the impact of male mass incarceration on HIV acquisition in women. The model was calibrated using surveillance data and assumed incarceration increased the number of sexual contacts and decreased HIV care engagement for men post-release. Incarceration of a partner increased the number of sexual contacts for women. We compared a counterfactual scenario with no incarceration to scenarios varying key parameters to determine what factors drove HIV acquisition in women.

Results

Setting the duration of male high-risk sexual behavior to two years post-release increased the number of HIV transmissions to women by more than 20%. Decreasing post-release HIV care engagement and increasing HIV acquisition risk attributable to sexually transmitted infections (STIs) also increased the number of HIV transmissions to women. Changing the duration of risk behavior for women, the proportion of women engaging in higher risk behavior, and the relative risk of incarceration for HIV-infected men had minimal impact.

Conclusion

The mass incarceration of African American men can increase HIV acquisition in African American women on a population-level through factors including post-release high-risk behaviors, disruption of HIV care engagement among formerly incarcerated men, and increased STI prevalence. These findings suggest that the most influential points of intervention may be programs seeking to reduce male risk behaviors and promote HIV care engagement post-release, as well as STI testing and treatment programs for recently incarcerated men, as well as women with incarcerated partners.

Condoms for prisoners: no evidence that they increase sex in prison, but they increase safe sex

Objectives

To determine if the provision of condoms to prisoners in two Australian state prison systems with different policies affects sexual behaviour. In New South Wales’ (NSW) prisons, condoms are freely distributed, while in Queensland prisons none are distributed.

Methods

We used a computer-assisted telephone interview to survey randomly selected prisoners in both states about their sexual behaviour in prison.

Results

Two thousand and eighteen male prisoners participated. The proportion of prisoners reporting anal sex in prison was equally low in NSW (3.3%) and Queensland (3.6%; p=0.8). A much higher proportion of prisoners who engaged in anal sex in NSW (56.8%) than Queensland (3.1%; p<0.0001) reported they had used a condom if they had had anal sex in prison. Sexual coercion was equally rare in both prison systems.

Conclusions

We found no evidence that condom provision to prisoners increased consensual or non-consensual sexual activity in prison. If available, condoms were much more likely to be used during anal sex. Condoms should be made available to prisoners as a basic human right.

Sex and condom use in a large jail unit for men who have sex with men (MSM) and male-to-female transgenders

Few data are available on factors contributing to sexual activity and condom use in custody settings, particularly among self-identified sexual minority prisoners. To address this gap, we undertook a study of sexual behavior and condom use of 101 randomly-selected men who have sex with men (MSM) and male-to-female transgender inmates in a segregated Los Angeles jail unit that has weekly condom access. Most survey participants (53%) reported anal sex during custody. Although 65% of these reported using condoms, 75% also reported having sex without condoms. Qualitative interviews (n=17) indicate a wide range of reasons for participating in protected and unprotected sex during custody, the use of cues within the custody environment to assess potential partners' HIV status, and support for increased condom availability. Findings also indicate that high-risk sex occurs frequently in this unit and that condom distribution likely prevents a substantial amount of related HIV/STD risk.

HIV risk behaviors, knowledge, and prevention education among offenders under community supervision: a hidden risk group

Numerous studies have established that incarcerated populations are at substantial risk for HIV infection. In response, many jails and prisons have increased HIV prevention and related services. However, although twice as many offenders are under community supervision as are incarcerated at any given time, HIV prevention needs have been largely ignored among probationers and parolees, and little is known about their HIV risk behaviors or HIV prevention needs. Compared with inmates, probationers and parolees have substantially greater opportunities to engage in HIV risk behaviors. In the present study, we describe HIV risk behaviors, knowledge, and prevention education experiences of probationers and parolees in New York City. We find that probationers and parolees have high rates of unprotected sex, and limited current exposure to effective HIV education and prevention interventions. Probation and parole departments need to improve HIV training for officers and make HIV risk reduction services more available.

Evaluation of the condom distribution program in New South Wales Prisons, Australia

Male to male unprotected anal sex is the main route of HIV transmission in Australia. The Australian Study of Health and Relationships, a large, representative population survey of sexual health behaviors, found that six percent of males in the general population have engaged in homosexual activity. These findings were consistent with studies in Europeand North America. Condoms have been shown to reduce the transmission of HIV in the community. Barriers to the use of condoms include access,stigma,and cost? Nevertheless, increased condom use has been reported among homosexual males, sex workers and injecting drug users although recent declines in condom use among homosexuals has presented new challenges in HIV prevention.

The prevalence of male to male sexual activity may be higher in prison than in the general population. Sexual activity in prison can be consensual and non-consensual involving both homosexual / bisexual and heterosexual men.

Acceptability of condom availability in a U.S. jail

Studies have documented the transmission of HIV in incarcerated populations resulting from injection drug use or sexual activity. Less than 1% of the jails and prisons in the United States allow inmates access to condoms, and none allows access to needles. Results of a survey to measure the acceptability of a condom distribution program at the Washington, DC. Central Detention Facility, where condoms are available to inmates, are presented here. Three hundred seven inmates and 100 correctional officers were surveyed from October 2000 through October 2001. The surveys demonstrate that the program is generally supported and thought to be important by inmates and correctional staff. The program has not resulted in any major security infractions and could be replicated in other correctional settings.

Human immunodeficiency virus in correctional facilities: a review

It is estimated that up to one-fourth of the people living with human immunodeficiency virus (HIV) infection in the United States pass through a correctional facility each year. The majority of persons who enter a correctional facility today will return home in the near future. Most inmates with HIV infection acquire it in the outside community; prison does not seem to be an amplifying reservoir. How correctional health services deal with the HIV-infected person has important implications to the overall care of HIV-infected people in the community. Routine HIV testing is well accepted. Combination antiretroviral therapy has been associated with a reduction in mortality in prisons. A link between area HIV specialists and correctional health care providers is an important partnership for ensuring that HIV-infected patients have optimal care both inside prison and after release.
