Background: An individual with chronic osteoarthritis (OA) is known to experience depressive symptoms frequently. Furthermore, OA is one of the most common conditions that cause disability, particularly in the elderly. Around 10% of individuals above 55 years old with knee OA experience severe disability. Therefore, this study aimed to analyze the contributing factors to depressive syndrome in individuals with knee OA.
Methods:A cross-sectional predictive linear regression multivariate design was employed, and sampling was conducted consecutively for 120 subjects with knee OA who participated in this study. Meanwhile, the severity of depressive syndrome was assessed using the Beck Depression Inventory-II (BDI-II).
Results:The majority of the samples were female (n=64, 53%), with a median age of 61 (40 -68), an average Body Mass Index (BMI) of 24.39+4.16, 70.83% (n=85) were married, and 49.17% (n=59) were employed. The median degree of knee OA in the sample was grade 3, the median level of experienced pain was 5 (3-7), and the BDI score was 21.23+7.16 (mild to moderate). The results of the multivariate linear regression analysis showed that income level (β = -4.127, p = <0.001), gender (β = 4.670, p = 0.003), BMI (β = 3.920, p = 0.02), degree of OA (β = 7.341, p = <0.001), and pain level (β = 6.528, p = <0.001) were associated with the severity of depressive syndrome (adjusted R2 = 74.7%).
Conclusion:This study indicated that there were several factors associated with the severity of depressive syndrome in individuals with knee OA. Income level acted as a protective factor, while gender, BMI, degree of OA, and pain level were aggravating factors for the severity of depressive syndrome.
