Abstract
U.S. Veterans and people living with HIV (PWH) experience higher rates of unhealthy alcohol and tobacco/nicotine use than non-Veterans and people without HIV (PWoH). Both groups are susceptible to adverse health outcomes associated with alcohol and tobacco/nicotine use. We explored awareness of alcohol- and tobacco/nicotine-related cancer and immune health risks among Veterans Health Administration (VA) patients with and without HIV. Among a sample of 41 (46% PWH; 73% male; 39% Black) purposively-selected VA patients receiving care 2020-2021 we conducted semi-structured interviews via telephone; interviews were recorded, transcribed and analyzed using a Rapid Assessment Process. Purposive selection was based on HIV status, alcohol and/or tobacco/nicotine use, and demographics. Among participants, 66% reported current smoking, and most screened positive for unhealthy alcohol use. Participants had high awareness of cancer and other health risks related to smoking but low awareness of synergistic risks and cancer risks associated with alcohol use despite awareness of a range of other alcohol-related risks. Awareness of alcohol and/or tobacco/nicotine's impacts on the immune system was variable. Findings did not distinctly differ between PWH and PWoH. Low awareness of alcohol-related cancer risk, risks of co-occurring use, and varying awareness of the impacts of alcohol and tobacco/nicotine on the immune system suggest a need for improved messaging regarding substance use-related cancer and immune risk. This may be especially important among PWH, for whom the prevalence and adverse effects of alcohol and tobacco use, and immune dysfunction are higher.
