Reciprocal Association Between Chronic Pain and Health Insurance Type in a Population-based Longitudinal Cohort Study.

Chronic pain is a widespread condition limiting adults' daily activities and labor force participation. In the United States, withdrawal from the workforce could be associated with loss of health insurance coverage, while lack of health insurance coverage can limit access to diagnosis and management of chronic health conditions. We used a longitudinal cohort study of middle-aged adults to investigate whether chronic pain is reciprocally associated with coverage by any insurance and type of insurance coverage over a 2-year period (2018 and 2020).
