Knee osteoarthritis (OA) and depression are both major health issues influencing the quality of elderly life. The aim of the present study was to explore the prevalence of depression and the factors influencing depression in community-dwelling elderly patients with OA of the knee in China.
We conducted a cross-sectional descriptive study. The study included 214 participants aged 60 and older diagnosed with OA of the knee. The depression of the elderly was measured by using the Geriatric Depression Scale (GDS). Participants were asked to complete a demographic questionnaire, the GDS, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the society dimension of Arthritis Impact Measurement Scales 2 (AIMS2). In addition, the participants performed a timed up and go test (TUG) and the stair-climb test (SCT).
The average age of the participants was 69.2 ± 7.63 years old, their body mass index (BMI) was 25.2 ± 3.85, and their disease duration was 5.9 ± 7.72 years. The mean total score of the GDS was 4.43 ± 2.89, and the GDS scores correlated positively with pain (r = 0.45, P < 0.001), stiffness (r = 0.40, P < 0.001), physical function (r = 0.52, P < 0.001),TUG (r = 0.35, P < 0.001), and SCT (r = 0.47, P < 0.001) and negatively with social support (r = - 0.35, P < 0.001).Analysis using multiple regression demonstrated that physical function, social support, and SCT explained 36.8% of the variance in depression.
Our findings suggested that physical function, social support, and lower extremity strength were predictors of depressive symptoms in community-dwelling elderly people with OA of the knee. Focusing on this elderly group with increasing functional exercise, positive social interaction and support, and lower limb muscle strength training should help in the prevention of depression.
膝关节骨关节炎（OA）和抑郁症都是影响老年人生活质量的主要健康问题。本研究的目的是探讨中国社区老年膝关节 OA 患者抑郁的患病率及影响抑郁的因素。
我们进行了一项横断面描述性研究。研究纳入了 214 名年龄在 60 岁及以上、诊断为膝关节 OA 的患者。采用老年抑郁量表（GDS）评估老年人的抑郁情况。参与者被要求完成一份人口统计学问卷、GDS、西安大略和麦克马斯特大学骨关节炎指数（WOMAC）、关节炎影响测量量表 2 的社会维度（AIMS2）。此外，参与者还进行了计时起立行走测试（TUG）和爬楼梯测试（SCT）。
参与者的平均年龄为 69.2±7.63 岁，体重指数（BMI）为 25.2±3.85，疾病病程为 5.9±7.72 年。GDS 的总分平均为 4.43±2.89，GDS 评分与疼痛（r=0.45，P<0.001）、僵硬（r=0.40，P<0.001）、躯体功能（r=0.52，P<0.001）、TUG（r=0.35，P<0.001）和 SCT（r=0.47，P<0.001）呈正相关，与社会支持（r=-0.35，P<0.001）呈负相关。多元回归分析表明，躯体功能、社会支持和 SCT 解释了抑郁症状 36.8%的方差。
我们的研究结果表明，躯体功能、社会支持和下肢力量是社区老年膝关节 OA 患者抑郁症状的预测因素。针对这一功能逐渐下降的老年人群，增加功能锻炼、积极的社会互动和支持、下肢肌肉力量训练有助于预防抑郁。
