슬관절 골관절염 증상이 환자에게 미치는 우울 효과
Osteoarthritis(OA) of the knee represents a common chronic disease, especially in the elderly, leading to functional impairment and disability. And OA patients have depressive symptoms frequently. Several factors contribute to the level of depressive symptoms. Authors tried to assess these factors and show effect of these factors to depressive symptoms. Through this study in the future physicians must consider psychiatric problems besides the pain itself in the treatment of OA patients.
Subjects included in this study were 64 knee joint OA patients. We obtained depressive symptoms from the CES-D(The Korean version of the Center for Epidemiological Studies-Depression Scale), level of pain, stiffness, functional disability from KWOMAC(WOMAC Korean Version 2, The Korean version of Western Ontario and Macmaster Osteoarthritis Index Score) and other factors able to contribute to depressive symptoms. RESULT: We divided the patients into two groups using CES-D cut-off score of 21. Each group consists of 46(CES-D<21) and 18(CES-D> or =21) patients. Frequency of sleep disturbance and pain consistency and level of pain, stiffness and functional disability were different significantly between two groups(p<0.0l). Through the correlation analysis level of pain, stiffness and functional disability were associated with CES-D score significantly(p<0.0l). And through the stepwise multiple regression analysis we demonstratred that the CES-D score influenced by level of functional disability, BMI, disease duration and, pain but only level of functional disability and BML were statistically significant(p<0.0l). Level of functional disability explained 46% of CES-D score(partial R2=0.46) so influenced on depressive symptoms most effectively.
This study suggested that functional disability was most important factors to explain depressive symptoms of knee joint OA patients.
