PREVALENCE OF DEPRESSION AND ITS IMPACT ON QUALITY OF SLEEP AMONG VARIOUS STAGES OF KNEE OSTEOARTHRITIS

Background: Knee osteoarthritis (OA) is a degenerative disease characterized by chronic pain and impaired mobility, which contribute significantly to psychological distress and poor sleep quality, elevating the overall disease burden. Objective: This study aims to determine the frequency of depression across different stages of knee OA and to evaluate its impact on sleep quality. Methods: Data were collected from 184 participants aged 45 to 70 years using non-probability convenience sampling. Depression was assessed using the Center for Epidemiologic Studies Depression Scale, sleep quality was measured with the Pittsburgh Sleep Quality Index, and knee OA severity was graded using the Kellgren and Lawrence system. The sample consisted of 110 males (59.8%) and 74 females (40.2%). Results: Of the total participants, 49.5% (n=91) showed no signs of depression. Mild depression symptoms were observed in 14.7% (n=27), moderate symptoms in another 14.7% (n=27), and severe symptoms were found in 21.2% (n=39). Sleep quality analysis revealed that while 52.2% reported good sleep quality, 22.8% had poor sleep, and 25% experienced severe disturbances. Conclusion: The study underscores a clear correlation between the severity of knee OA and the incidence of depression, which significantly affects sleep quality. Addressing mental health issues in these patients could improve sleep and overall well-being.
