Epidemiological and population-based investigations of persons infected with HIV

I am a demographer who is currently involved in observational research into the impact of antiretroviral therapy on quality of life and life expectancy of persons with HIV disease in British Columbia. I am also interested in issues regarding access to antiretroviral therapy in developing nations. My most significant contributions to HIV research include: Studies monitoring seroincidence and determinants of HIV infection and risk behaviour among gay and bisexual men In a natural history study of HIV-positive gay and bisexual men, we demonstrated that lower socioeconomic status decreases the length of survival. Low income was significantly associated with shorter survival from HIV infection to death, even after adjustment for CD4 count (which measures immune suppression in persons with HIV), age at infection, year of infection and use of HIV therapies and prophylaxis. Studies measuring the impact of HIV infection on population health My primary goal in the area of population health research has been examining the impact of HIV on patterns of mortality, migration and hospitalization in Canada. One study I conducted showed that although there are barriers to widespread HIV treatment, limited used of antiretroviral therapy could have an immediate impact on South Africa’s AIDS epidemic. A second study demonstrated that the cost of making combination antiretroviral therapy available worldwide would be exceedingly high, especially in countries with limited financial resources. Studies evaluating the impact of antiretroviral therapy on the health and well-being of persons with HIV disease One of my studies demonstrated a significant reduction in mortality and AIDS-free survival for HIV infected individuals who initiated therapy with regimens including stavudine or lamivudine compared to those who initiated therapy with regimes limited to zidovudine, didanosine and zalcitabine.
