Characteristics of physically inactive older adults with arthritis: results of a population-based study.
BACKGROUND
Arthritis is the most prevalent chronic condition among persons age 65 and older in North America. Physical inactivity in this population is linked to functional limitations, increased risk for cardiovascular disease, diminished quality of life, and disability. The purpose of this study was to identify risk factors for inactivity.


METHODS
National data for 6256 community-dwelling older adults with arthritis from the 1996-1997 Canadian National Population Health Survey were examined using logistic regression analyses. The independent variables included sociodemographic characteristics, health status, psychosocial factors, health behaviors, and medication use.


RESULTS
Inactive persons were significantly (P < 0.05) more likely to be women, older (75+), have functional limitations, be underweight (BMI < 20) or overweight (BMI > 25), have severe pain, or not have prescription drug insurance coverage. The same group was less likely to be unmarried, well educated, from western provinces, attend church frequently, consume alcohol infrequently, have higher levels of social support, have better self-rated health, or use pain medication.


CONCLUSIONS
The profile presented in this study should be fully considered by health care providers when educating patients with arthritis about the adverse health effects of sedentary behavior. Prescription drug insurance coverage may facilitate activity among elders with arthritis.
