目的分析北京广外社区55岁以上居民踝臂血压指数变化与心血管病相关危险因素关系。方法选取2014—2015年“十二五”国家科技支撑计划项目广外社区协作组55岁以上361例人群资料,通过问卷调查了解人群基本情况、家族史、生活方式及行为相关危险因素;体格检查收集调查对象的身高、体重、腰围、血压,踝臂血压、身体脂肪率,利用SPSS 19.0软件包进行统计分析。结果 1调查人群踝臂血压指数(ABI)均值为(1.22±0.11),其中男性水平(1.26±0.11)和女性ABI值(1.21±0.11)之间差异无统计学意义(P=0.306);2方差分析比较各年龄组之间ABI值的差异显著(P<0.05);3高血压组ABI值(1.21±0.10)与非高血压组ABI值(1.24±0.11)相比,两组差异具有统计学意义(P=0.033)。对生活方式和行为、家族史等因素进行Logistic回归分析得出:BMI、年龄、身体脂肪率、高血压家族史是影响ABI变化的主要影响因素。结论随着年龄增长,ABI值逐渐下降,高血压、年龄、体质指数、身体脂肪率和家族高血压病史是踝臂血压指数异常的重要影响因素。通过对踝臂指数的监测,可以有针对性开展高危人群心血管疾病早期评估和干预。
Objective To analyze the relationship between the changes of ankle-brachial pressure index and the risk factors associated with cardiovascular disease in residents over 55 in Beijing’s Guang-Wai community. Methods A total of 361 subjects over 55 years of age in Guangsai Community Collaborative Group from 2014 to 2015 in the “Twelfth Five-Year Plan” National Science and Technology Support Program were selected to investigate the basic risk factors, family history, lifestyle and behavioral risk factors through questionnaire. Physical examination The subjects’ height, weight, waist circumference, blood pressure, ankle-brachial blood pressure and body fat percentage were collected and analyzed by SPSS 19.0 software package. Results 1 The ABI of the surveyed population was (1.22 ± 0.11), and there was no significant difference between the male level (1.26 ± 0.11) and female ABI (1.21 ± 0.11) (P = 0.306); 2 Analysis of variance showed significant differences in ABI values among all age groups (P <0.05); ABI of hypertension group (1.21 ± 0.10) was significantly higher than that of non-hypertension group (1.24 ± 0.11) Significance of learning (P = 0.033). Logistic regression analysis of lifestyle and behavior, family history and other factors concluded that BMI, age, body fat rate and family history of hypertension were the main influencing factors of ABI. Conclusions With age, the ABI value decreased gradually. The history of hypertension, age, body mass index, body fat percentage and family history of hypertension were the important influencing factors of ABA. By monitoring the ankle-brachial index, early assessment and intervention of cardiovascular disease can be targeted in high-risk groups.
