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. A questionnaire covering sociodemographic, health, and caregiving variables was completed by each study participant. Caregiving variables examined characteristics of the person who received the most care from the questionnaire respondent, as well as the types of caregiving (e.g., hands-on versus hands-off tasks) and amount of care provided (e.g., hours per week). Results: There was no difference in the proportion of people with and without arthritis who provided informal care (46%). Individuals with arthritis reported worse health, but this did not affect the likelihood of providing care, nor the types or amount of care provided. Caregivers with and without arthritis were most likely to provide fewer than 7 hours per week of care, and the most common type of care was characterized as hands-off, particularly transportation assistance. Men were just as likely to provide care as women but were less likely to provide high intensity care or perform hands-on tasks. Conclusion: Despite reporting worse health on average, people with arthritis were just as likely as people without arthritis to provide informal care. The need to provide informal care among people with arthritis may impact their ability to engage in self-management activities for their arthritis.
