Objective: Despite the joint pain and significant dysfunction that characterizes arthritis, many people with arthritis continue to carry out everyday duties and responsibilities. The objective of the present study was to describe participation in informal caregiving (unpaid assistance to someone with a health issue or limitation) among people with arthritis. Methods: Analysis of baseline data from the Canadian Longitudinal Study on Aging (CLSA), a nationally representative sample of people ages 45–85 years (n = 21,241), was performed.
