Demographics of cancer screening in Providence’s homeless population.

Abstract

1585 Background: Adults experiencing homelessness have a higher incidence and mortality from cancer. It is estimated that almost 60% of homeless people in the US are from racial and ethnic minorities. Therefore, cancer mortality among the homeless may be an important disparity. In recent years homelessness has increased in Providence RI due to high rents and end of covid subsidies. The objective of this project was to learn about the demographics of the homeless population in Providence, focusing on risk factors for cancer and barriers to screening, to acquire the necessary information to develop interventions to improve cancer screening in the unhoused population. Methods: We conducted a cross-sectional survey of homeless individuals in Providence, RI. Survey data was obtained at homeless shelters, on the street, at soup kitchens and at other community events supporting the homeless. The largest single source of participants was those attending the Matthewson Street Church Friendship Breakfast on Sunday mornings. Results: Data was obtained from 278 homeless individuals from September 2023 to December 2023. 70% were male, 30% female. Age ranges included 28 (10%) < 40 years, 78 (28%) 40-49 years, 88 (32%) 50-59 years, 74 (27%) 60-69 years and 10 (4%) > 70 years. Race/ethnicity included 56% White, 18% Black, 13% Hispanic/Latino, 2% Native American, 9% multiracial and 2% other. 51% were sleeping in a shelter, 29% were unsheltered (including outside, car or tent), 12% “couch surfing”, and 7% were recently housed. Most participants (92%) had health insurance, the majority being state Medicaid, and had PCP visits (59%), mostly to community health centers, within the last 12 months. 72% of individuals were current cigarette smokers and 45% currently used alcohol. Among women, only 32% were on schedule for mammogram and 61% were on schedule for cervical cancer screening. Colon cancer screening rate for individuals > 45 years was 32%. Only 32% of males over 50 had prostate cancer screening. Barriers identified included needing to have other needs met such as food and housing, lack of transportation to healthcare facilities, and lack of awareness about the need to undergo screening. Conclusions: The most common age range of homelessness in Providence, ages 50-59, is when cancer screening should be ongoing. There is a higher incidence of homelessness among minorities. The homeless population have high risk factors for cancer but screening rates for breast, cervical, lung, prostate and colon cancer are well below national guidelines. This represents a health disparity. Given the proportion of participants with a PCP and health insurance, interventions to improve cancer screening in this population may be feasible. We plan to develop educational partnerships with community health centers during the next phase of this initiative to increase awareness and uptake of screening recommendations.
