Abstract

Background

Osteoarthritis is the most common chronic joint disease. In the absence of an effective medical treatment and due to the chronic nature of this condition, an osteoarthritis medical diagnosis may finally result in decreased health-related quality of life. Therefore, the aim of this study was to measure the impact of the osteoarthritis medical labelling on physical and mental health-related quality of life.

Methods

Subjects (n = 1132, 58.7% women) were approached as participants of an urban population-based cohort (EPIPorto). Self-reported information on previous diagnosis of knee, hip or hand osteoarthritis was obtained and rheumatologists established knee, hip or hand osteoarthritis clinical diagnosis in symptomatic individuals. Physical and mental dimensions of health-related quality of life were evaluated using the self-administered Medical Outcomes Study: 36-Item Short Form Survey. Crude and adjusted linear regression coefficients (beta) and the corresponding 95% confidence intervals (95% CI) were computed to estimate the associations between being labelled as an osteoarthritis case and health-related quality of life.

Results

Regardless of disease medical labelling, individuals with osteoarthritis scored significantly lower physical health-related quality of life when compared to those without joint disease (kneeunexposed: beta = −5.3, 95% CI: −7.6, −3.1; kneeexposed: beta = −6.0, 95% CI: −8.4, −3.7; hipunexposed: beta = −6.0, 95% CI: −9.8, −2.3; hipexposed: beta = −11.0, 95% CI: −15.6, −6.4; handunexposed: beta = −4.3, 95% CI: −6.5, −2.0; handexposed: beta = −4.3, 95% CI: −6.6, −2.1). The same was not observed regarding mental health-related quality of life. Among subjects with clinically confirmed osteoarthritis, the medical labelling of this joint disease was not significantly associated to health-related quality of life.

Conclusions

The labelling of knee, hip and hand osteoarthritis diagnosis may not add specific benefit to osteoarthritis patients in terms of its capability to improve health-related quality of life.
