Cancer risk behavior and healthcare utilization among people experiencing homelessness in Europe

BACKGROUND: People experiencing homelessness (PEH) are a vulnerable population, having higher cancer morbidity and mortality compared to the housed population. Reasons for this may be due to higher prevalence of risky health behaviors but also owning to barrier to access and utilize healthcare services. This study aimed to show the prevalence of risky health behavior and utilization of healthcare services in PEH in Austria, Greece, Spain and the UK. METHODS: Data from 262 PEH participating in an ongoing longitudinal study on cancer prevention and early detection were included in a preliminary analysis (03/2023). Participants were adults, with no history of cancer recruited during their visits to social and healthcare services. Demographic data, high-risk health behaviors and visits to healthcare services were collected via questionnaires. RESULTS: Mean age of participants was 47.6 years (SD = 12.9) with 56.2% identifying themselves as male. The majority (50.4%) were homeless for up to 3 years and 61.6% had no history of homelessness. On average, 13.6 (SD = 10.2) cigarettes per day were reported by 62% of active smokers, 51% reported regular alcohol intake and 20.6% reported use of illicit drugs. Multimorbidity (co-occurrence of two or more chronic illnesses) was prevalent in 20.2% of participants. Half of participants reported having health insurance and 55% reported utilizing health care services in the past 12 months. The average number of visits to general practitioners and medical specialists was 3.9 (SD = 5.5) and 2.1 (SD = 5.1), respectively with an average of 2.2 (SD = 7.3) nights spent in hospital. CONCLUSIONS: The proportion of PHE engaging in high-risk health behaviors is higher and utilization of health services is lower compared to the housed population. PEH may benefit from improved access to preventive and community health services, which is currently assessed by implementing the Health Navigator Model as part of the Horizon 2020 CANCERLESS project (GA965351). KEY MESSAGES: • High prevalence of risky health behaviors and multimorbidity in PEH was observed. • The reported low health care utilization among PEH may be due to structural barriers.
