Objectives: We aimed to describe the characteristics of caregivers with cancer compared to those without and analyze the association between having cancer and caregivers’ psychological distress in Japan. Methods: We used data from the Japanese Comprehensive Survey of Living Conditions in 2010, 2013, and 2016. The participants were 5258 family caregivers aged ≥40 years, caring for only one family member whose information in the dataset was available for all the covariates included in the model.
