我国社区中老年人膝骨关节炎的发病趋势分析

目的观察探讨我国社区中老年人膝骨关节炎的X线片特征、流行病学特征、临床症状与其发病趋势间的相关性。方法选取我国22个社区2009年5月～2011年5月年龄>50岁的膝关节炎患者1072例,均采取X线片检查、体格检查、问卷调查,观察其检查及调查结果。结果 1072例膝关节炎患者的不同年龄与发病率间比较呈正相关关系(r=0.78,P<0.05),具有统计学意义。临床症状、体征及X线分级与发病率的关系无明显的相关性(r=-0.042,0.021,-0.054,P>0.05),无统计学意义。结论我国社区中老年人膝骨关节炎的发病趋势是随着年龄增长逐渐呈上升的趋势,以慢性、老年性发病为主要的流行病学特征。
