Previously we assessed risk factors for FEV(1) decline in children and adolescents using the Epidemiologic Study of Cystic Fibrosis (J Pediatr 2007;151:134-139); the current study assessed risk factors in adults.
Risk factors for FEV(1) decline over 3-5.5 years for ages 18-24 and ≥25 years were assessed using mixed-model regression.
Mean rates of FEV(1) decline (% predicted/year) were -1.92 for ages 18-24y (n=2793) and -1.45 for ages ≥25y (n=1368). For the 18-24y group, B. cepacia, pancreatic enzyme use, multidrug-resistant P. aeruginosa, cough, mucoid P. aeruginosa, and female sex predicted greater decline; low baseline FEV(1) and sinusitis predicted less decline. For the ≥25y group, only pancreatic enzyme use predicted greater decline; low baseline FEV(1) and sinusitis predicted less decline.
Risk factors for FEV(1) decline in adults <25 years are similar to those previously identified in children and adolescents; older adults had few statistically significant risk factors.
此前,我们使用囊性纤维化的流行病学研究(J Pediatr 2007;151:134-139)评估了儿童和青少年 FEV1 下降的危险因素;本研究评估了成年人的危险因素。
使用混合模型回归评估了 18-24 岁和≥25 岁人群中,FEV1 在 3-5.5 年内下降的危险因素。
18-24 岁组(n=2793)和≥25 岁组(n=1368)FEV1 年下降率(%预计值/年)分别为-1.92 和-1.45。在 18-24 岁组中,洋葱伯克霍尔德菌、胰酶使用、多药耐药铜绿假单胞菌、咳嗽、粘液型铜绿假单胞菌和女性性别预示着更大的下降;低基线 FEV1 和鼻窦炎预示着下降较小。在≥25 岁组中,只有胰酶使用预示着更大的下降;低基线 FEV1 和鼻窦炎预示着下降较小。
18-24 岁以下成年人 FEV1 下降的危险因素与先前在儿童和青少年中确定的危险因素相似;老年患者的统计学显著危险因素较少。
