| 目的 探讨老年人体成分对老年症状性膝骨关节炎(SKOA)患者管理与康复的意义。方法 选取2018年11月至2019年7月在北京某社区采用结构化问卷收集的681例老年人资料,采用生物电阻抗分析(BIA)法测量体成分,评估体成分与SKOA的关系,并依据体质量指数(BMI)和肌肉百分比将受试者分为4个亚组,分析各亚组患SKOA的风险。结果 老年女性的SKOA患病率高于男性(44.3%比32.4%,P＜0.05),但两组间BMI差异无统计学意义[(23.8±3.5)kg/m2比(24.2±3.1)kg/m2,P=0.153],而女性的体脂百分比高于男性(34.0±7.4比29.3±6.4,P＜0.001),躯干肌肉百分比(28.5±3.4比31.0±3.0,P＜0.001)和下肢肌肉百分比(19.0±3.0比22.2±2.9,P＜0.001)低于男性。老年女性的SKOA患病风险与BMI和体脂百分比呈正相关,与躯干肌肉百分比和下肢肌肉百分比呈负相关。在男性中,SKOA患病率仅与躯干肌肉百分比负相关,与BMI、体脂百分比和下肢肌肉百分比均无明显关系。肥胖且肌肉百分比较低的老年女性和男性患SKOA的风险都显著较高,OR(95%CI)值分别为2.24(1.35,3.71)、2.31(1.18,4.53)。结论 体成分与老年女性SKOA密切相关。使用BMI结合体成分分析可能有助于了解SKOA患者的身体特点。 |

| Objective To explore the significance of body composition of the elderly in the management and rehabilitation of elderly symptomatic knee osteoarthritis (SKOA) patients.Methods Selected the data of 681 elderly people collected using a structured questionnaire in a community in Beijing from November 2018 to July 2019. Body composition was measured by bioelectrical impedance analysis (BIA), and the relationship between body composition and SKOA was evaluated. The subjects were divided into four subgroups according to body mass index (BMI) and muscle percentage, and the risk of SKOA in each subgroup was analyzed.Results The prevalence of SKOA in elderly women was higher than that in men (44.3% vs.32.4%,P<0.05), but there was no significant difference in BMI [(23.8±3.5) kg/m2 vs.(24.2±3.1) kg/m2,P=0.153].The percentage of body fat in women was higher than that in men (34.0±7.4 vs.29.3±6.4, P<0.001), and the trunk muscle percentage (28.5±3.4 vs.31.0±3.0,P<0.001) and the lower limb muscle percentage (19.0±3.0vs.22.2±2.9,P<0.001) were lower. The risk of SKOA in elderly women was positively correlated with BMI and body fat percentage, and negatively correlated with trunk muscle percentage. In men, the prevalence of SKOA was only negatively correlated with trunk muscle percentage, but not with BMI, body fat percentage and lower limb muscle percentage. Elderly women and men who were obese with lower muscle percentage have a significantly higher risk of SKOA, with OR (95%CI) values of 2.24 (1.35,3.71) and 2.31 (1.18,4.53), respectively.Conclusion Body composition is closely related to SKOA in elderly women. Using BMI combined with body composition analysis may help to understand the physical characteristics of SKOA patients. |
