我国年龄≥35岁人群臂间收缩压差及影响因素

Inter-arm systolic blood pressure difference and its influencing factors in people aged≥35 years in China

目的 了解我国年龄≥35岁人群臂间收缩压差(IASBPD)增大的检出情况及相关影响因素。方法 采用分层多阶段的抽样方法从31个省(自治区、直辖市)随机选择2012—2015年262个城市和农村的常住居民。采用简单随机抽样方法在东部、中部和西部地区选取16个城市和17个农村。剔除信息缺失人数后共获得年龄≥35岁研究对象34 121人进行分析。数据采用问卷收集方式,采用踝臂血压指数测量仪测量双臂血压。所有数据采用SPSS 23.0软件进行统计分析。连续数据用均数±标准差(x±s)表示,组间比较符合正态分布采用F检验,不符合正态分布采用秩和检验。分类资料用频数和率或构成比表示,各种率及构成比的比较用χ2检验。采用多因素logistic回归分析IASBPD增高的影响因素。结果 总人群IASBPD≥10和≥15 mmHg的检出率分别为16.31%、7.55%。多因素logistic回归发现,年龄增大、高血压家族史、低高密度脂蛋白胆固醇(HDL-C)血症、高血压、腹型肥胖是IASBPD≥10与≥15 mmHg的危险因素(均P<0.05)。结论 我国年龄≥35岁人群IASBPD≥10与≥15 mmHg的检出率分别为16.31%、7.55%,并且年龄、低HDL-C血症、高血压家族史、高血压和腹型肥胖为IASBPD增大的影响因素。

Objective To investigate the detection rate of the increase of inter-arm systolic pressure difference(IASBPD)in people aged≥35 years in China and the related factors.Methods Stratified multi-stage sampling method was used to randomly select 262 urban and rural residents from 31 provinces,autonomous regions and municipalities.from 2012 to 2015.Simple random sampling method was used to select 16 cities and 17 areas from eastern,central and western regions.A total of 34121 subjects aged≥35 years were analyzed after removing the missing information.Data were collected by questionnaire,and blood pressure in both arms was measured by ankle-brachial index meter.All data were analyzed by SPSS 23.O software.Continuous data were expressed as meanstandard deviation,and compared between groups using F-test if they were normal distribution,and using rank-sum test if not.Categorical data were expressed as frequency,rate or constituent ratio,and were compared using x^(2) test between groups.Multivariate logistic regression was used to analyze the influencing factors of IASBPD increase.Results The detection rates of IASBPD≥10 mmHg and≥15 mmHg were 16.31%and 7.55%,respectively.Multivariate logistic regression showed that age,family history of hypertension,low high density lipoprotein cholesterol(HDL-C),hypertension and abdominal obesity were risk factors of IASBPD≥10 mmHg and≥15 mmHg(all P<0.05).Conclusions The detection rates of IASBPD≥10 and≥15 mmHg in Chinese people≥35 years old are 16.31%and 7.55%,respectively,Age,low HDL-C,family history of hypertension,hypertension and abdominal obesity are the influencing factors of IASBPD increase.
