目的 调查华南地区哮喘患者哮喘控制感知力(PCA)水平,探讨影响PCA水平的主要因素.方法 入选我院门诊2009年3月～2010年4月就诊150例哮喘患者,年龄19～65(38.6±11.7)岁,男86例,女64例;间歇和轻度持续患者46例、中度持续49例、重度持续55例,调查其人口学特征、完成哮喘控制感知力问卷(PCAQ-6)、哮喘控制问卷(ACT)、标准化哮喘患者生活质量问卷(AQLQ(S)),并收集患者填写问卷当日肺功能检查结果、外周血、诱导痰细胞分类计数.结果 我院150例符合入组条件患者均完成PCAQ-6填写及上述指标采集,PCAQ-6评分范围在10～26(18.75+3.42)分.男性(18.6±3.28)分,女性(18.95±3.6)分,显著低于国外调查水平(P＜0.001).PCA与哮喘控制水平(rP=0.377,P=0.000)及哮喘相关生活质最(rP=0.675,P=0.000)显著相关.多元线性回归分析结果示:PCA与FEVl占预计值百分比(FEVl%)及与外周血嗜中性粒细胞百分比显著正相关,而与哮喘病程(年)显著负相关.结论 我国华南地区哮喘患者PCA水平低下,PCA可影响哮喘控制水平及哮喘生活质量,哮喘病程(年)及肺功能水平及外周血中性粒细胞百分比是PCA主要影响因素.%Objective To investigate the level of the patients' perceived control of asthma (PCA) in South China and analyze the risk factors contributing to inadequate PCA. Methods A total of 150 asthmatic out-patients consisting of 86 males and 64 females aged 19-65 (38.6±11.7) years were enrolled in this investigation. The patients were asked to complete questionnaires of the demographic data, perceived control of asthma (PCAQ-6) scales, asthma control test (ACT) scales and Standard asthma-specific quality of life [AQLQ(S)] scale. The data of spirometric measurements, blood cell count and induced sputum cell count were also collected. Results All the 150 asthmatic out-patients recruited completed the questionnaires and examinations. The PCAQ-6 scores ranged from 10 to 26 (18.75±3.42) in these patients (18.6±3.28 in male and 18.95±3.6 in female patients), significantly lower than those reported in other countries (P<0.001). PCA was positively correlated to the level of asthma control (rp=0.377, P=0.000) and AQLQ(S) scores (rp=0.675, P=0.000). Multiple linear regression showed that PCA was positively correlated to FEV1% and blood neutrophil counts, and inversely to asthma duration. Conclusions The level of the PCA appears inadequate in South China. The PCA can affect the level of asthma control and asthma-specific quality of life. The factors contributing to inadequate PCA include primarily asthma duration, lung function and blood neutrophil counts.
