摘要 目的 探讨老年人收缩压夜间下降百分比(NRR)的临床参考值范围及其影响因素.方法 对1207例老年人[(男996例,女211例),年龄67~93(76.00±6.00)岁]进行问卷调查、体格检查、实验室检查和24 h动态血压检测;使用百分位数法确定378例正常老年人(指无高血压和脑梗死病史的老年人)收缩压NRR的临床参考值范围,运用单因素分析和多元回归分析确定1207例老年人收缩压NRR的影响因素.结果 正常老年人收缩压NRR的95%临床参考值范围为-11.14%-20.55%.老年人收缩压NRR的影响变量有性别(β=-2.048,P=0.005)、年龄(β=-0.212,P=0.001)和脑梗死(β=-3.753,P=0.0000).结论 为便于临床应用,可将老年人收缩压NRR的临床参考值范围定为-10%~20%.老年人收缩压NRR与性别、年龄和脑梗死等因素有关.
