The findings are available now in the online edition of the journal "AIDS and Behavior" and are scheduled for publication in an upcoming print issue.
"We found the greatest and most sustained reductions in sexual risk took place when the prevention interventions were delivered by medical care providers during HIV patients' routine visits. An important feature of this research is that it was conducted in actual clinical settings and not in the somewhat artificial setting of a clinical trial," said the study's lead author, Janet J. Myers, PhD, MPH, assistant professor of medicine at the UCSF Center for AIDS Prevention Studies and co-principal investigator of the project.
When they received risk assessment prevention counseling from their clinical providers, HIV patients showed a consistent decline in risky behavior over the 12-month study period. The researchers saw HIV patients cut almost in half their sexual risk behaviors: unprotected anal or vaginal intercourse with either a HIV-negative partner or one whose status was unknown. HIV patients receiving services from health educators, social workers or peer educators also significantly reduced risk behaviors at 6 months, but not at 12 months.
"Other studies testing behavioral prevention interventions have demonstrated that boosters delivered at periodic intervals assist in sustaining behavior changes. Since patients see their medical providers regularly to monitor disease and therapeutic regimens, delivering prevention services during these visits is not only exceedingly effective in reducing risk behaviors, but is likely to be highly cost-effective," said Steve Morin, PhD, professor of medicine and director of the UCSF Center for AIDS Prevention Studies and the study's principal investigator.
The roughly 3500 HIV-positive trial participants were diverse—half of the sample was men who have sex with men, 30 percent was women and 20 percent was heterosexual men. The research was conducted at 13 demonstration sites in 12 states and included sites in major urban centers and sites in smaller cities.
"These findings are very robust given the number of participants and their diversity and the variety of sites where the research was conducted. This intervention, especially when delivered by medical care providers, should be considered for inclusion in emerging 'test and treat' and 'test, treat and link to care' models that seek to dramatically increase the number of HIV-infected patients receiving care. The expected prevention benefits from increasing the number of people who know their HIV status and from successfully achieving some viral control amongst those infected could be effectively and efficiently increased if these behavioral interventions are included as part of a combination HIV prevention effort," said Morin.
Study co-authors include Starley B. Shade, Carol Dawson-Rose, Kimberly Koester, Andre Maiorana, Jennifer Bie, and Mi-Suk Kang-Dufour from the UCSF Center for AIDS Prevention Studies and Faye E. Malitz from the HIV/AIDS Bureau of the U.S. Health Resources and Services Administration (HRSA).
The research was supported by the HRSA Special Projects of National Significance Program.
Established in 1986, the UCSF Center for AIDS Prevention Studies conducts domestic and international research to prevent the acquisition of HIV and to optimize health outcomes among HIV-infected individuals.
The UCSF Center for AIDS Prevention Studies is affiliated with the AIDS Research Institute (ARI) at UCSF. UCSF ARI houses hundreds of scientists and dozens of programs throughout UCSF and affiliated labs and institutions, making ARI one of the largest AIDS research entities in the world.
UCSF is a leading university dedicated to defining health worldwide through advanced biomedical research, graduate level education in the life sciences and health professions and excellence in patient care.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
