50 Background: Incarceration history is linked to limited access to care, including cancer screenings. Adverse consequences may also extend to their partners due to financial burdens and social stigma. This study examined associations of individual and partner incarceration history and receipt of cancer screenings in the United States. Methods: We identified individuals aged ≥ 50 years currently living with a partner who responded to the 2014-2020 Health and Retirement Study. Incarceration history was defined from responses to the question ‘Have you ever been an inmate in a jail, prison, juvenile detention center, or other correctional facility?’ People were categorized into 3 groups: 1) without individual or partner incarceration history, 2) with individual incarceration history only, and 3) with partner incarceration history only. People with both individual and partner incarceration history were excluded due to small sample size. We used multivariate logistic regression models to generate prevalence ratios (PRs) comparing receipt of any breast, cervical, and colorectal cancer screenings ≤2 years among screening-eligible people (defined by the US Preventive Services Taskforce guideline) with individual or partner incarceration history to people without incarceration history, stratifying by sex and controlling for age group, race and ethnicity, educational attainment, and comorbidity. Results: Of the sample, 0.9% and 11.8% of females and males reported individual incarceration history, respectively; 11.1% and 1.0% reported partner incarceration history, respectively. Compared to females without individual or partner incarceration history, women with partner incarceration history were less likely to receive breast cancer screening (PR:0.7, 95CI: 0.5-0.9); women with individual incarceration history were less likely to receive colorectal cancer screening in the past 2 years (PR: 0.7, 95% CI: 0.5-0.9). Compared to males without individual or partner incarceration history, men with partner incarceration history were less likely to receive colorectal cancer screening (PR: 0.5, 95% CI: 0.4-0.7). Conclusions: Individual or partner incarceration history was associated with lower prevalence of cancer screening. Programs to improve access to care and cancer screening among both people with incarcerations history and their partners are warranted.
