在大多数对老年人的大型研究中，体位性低血压(PH)的患病率约为20%；然而，这些研究并不排除患有已知的引起PH的疾病和药物的受试者。我们试图确定在健康、社区生活的老年人中的PH患病率，并与那些已知的疾病危险因素的人进行对比。我们测量了300名独立生活的老年人的仰卧位血压和一分钟站立血压，这些老年人访问了老年人健康筛查计划。受试者分为两组：已知危险因素组(n=175)和无危险因素组(n=125)。整个人群的PH(收缩压下降，大于或等于20毫米汞)的患病率为10.7%。有危险因素组患病率为13.7%(24/175)，无危险因素组患病率为6.4%(8/125)。仰卧位高血压与PH有关，但PH的出现与年龄、跌倒病史、站立症状或最近进食之间没有关系。这些数据表明，在健康的老年人中，PH是一个相对罕见的发现，其患病率与危险因素显著相关，与跌倒或症状的关联可能比之前报道的要少。
Postural hypotension (PH) has a prevalence of about 20% in most large studies of elderly individuals; however, these studies do not exclude subjects with diseases and medications known to cause PH. We sought to determine the prevalence of PH in healthy, community-living, elderly individuals in contrast to those with known risk factors for the condition. We measured supine and one-minute standing blood pressures in 300 independently living elderly persons who visited a senior citizen health screening program. Subjects were divided into two groups: those with known risk factors (n = 175) and those without (n = 125). The prevalence of PH (systolic decrease, greater than or equal to 20 mm Hg) for for the entire population was 10.7%. In the group with risk factors, the prevalence was 13.7% (24/175), compared with 6.4% in the group without risk factors (8/125). Supine hypertension was associated with PH, but there was no relationship between the presence of PH and age, history of falls, symptoms on standing, or recent meal. These data suggest that PH is a relatively uncommon finding in healthy elderly, its prevalence is significantly related to risk factors, and its association with falls or symptoms may be less than previously reported.
