Osteoarthritis (OA) is one of the principal causes of pain and disability. For disease prevention and overall treatment, proper health-related behavior becomes a much critical factor in maintaining optimal health status.

In above context, a study was conducted to estimate the association between health-related behaviors and reported pain & disability among OA patients' as well as their acceptance of the disease.

A total of 198 participants were included. The ACR criteria (1988) were used to diagnose OA among participants. The methods used were pain VAS, disability index, acceptance of illness scale, health and behavior inventory and health assessment questionnaire disability index.

The average age of patients participated in the study was 59.16 years, and they all were suffering from OA since last 5.5 years. The positive correlation was noticed in pain experienced both during movement and at rest with the physical disability. Also, a positive linear correlation was observed between the age and physical disability. Acceptance of the disease (AIS) depends mostly on age, on pain in motion and at rest and on the disability levels. Study of the health-related behaviors (IZZ) shows that the average severity of declared behavior is considerably important with the physical disability (HAQ DI) (p = 0.029).

The overall results of the study confirm that the acceptance of illness is significantly reduced with age and increasing levels of disability as well as with the severity of pain. The progressive levels of disability and the younger age of the participants drive them to involve in beneficial health behavior.
