Prevalence and risk factors of osteoarthritis in patients at a public hospital in Limpopo province

Abstract

Background: Osteoarthritis (OA) is a public health concern affecting millions globally. Osteoarthritis has been ranked as the 12th leading cause of disability among the ageing population globally. In addition, OA can lead to disability, which can affect the quality of life and physical and emotional well-being.

Methods: A cross-sectional survey was conducted. An interviewer-administered questionnaire was utilised. Logistic regression was used to identify OA-related factors in the univariable and multivariable models. A p-value less than 0.05 was deemed statistically significant.

Results: A total of 210 participants responded to the questionnaire. The overall prevalence of OA at the public hospital was 55.7% in adults over 18 years willing to participate. Among the study participants, females, individuals over the age of 50 years, and obese patients reported a high prevalence of OA. Family history and knee and hip pain were significantly associated with OA (p < 0.05). Participants with a family history of OA were 6.9 times more likely to have OA, those with knee pain were 22.8 times more likely and those with hip pain were 5.5 times more likely after adjusting for the other variables.

Conclusion: A high proportion of patients reported to have OA. Family history, knee pain and hip pain were strongly associated with OA. Understanding the prevalence and risk factors associated with OA is crucial for developing targeted interventions for prevention and management.

Contribution: Targeted health promotion and education interventions are needed for prevention and early management.
