在接受哮喘评价的少数民族儿童中,超重和肥胖与肺功能值有关

摘要
背景:少数民族儿童的超重、肥胖和哮喘更为常见,然而少数民族哮喘患儿中,超重和肥胖与肺功能值的关系尚未完全清楚。
目的:在纽约布朗克斯一个大型市内医院接受哮喘评价的儿童中,研究体重、种族和肺功能值的关系。
方法:对980名年龄7~20岁的哮喘患儿初次呼吸科门诊的肺功能检测值进行回顾性分析。白人、非洲裔美国人和西班牙裔美国人中,采用线性回归分析超重和肥胖儿童以及正常体重儿童的超重和肥胖与肺功能的关系。
结果:与白人相比(51.2%),更多的非洲裔美国人(58%)和西班牙裔美国人(65.4%)存在超重和肥胖(p < 0.05)。与正常体重儿童相比,超重和肥胖的非洲裔美国人(分别为2.99%, p < 0.05;3.56%, p < 0.01)和西班牙裔美国人(分别为2.64%, p < 0.05;2.36%, p < 0.05)第一秒用力呼气体积(FEV1)与用力肺活量(FVC)的比值显著下降,这种现象在肥胖的白人中也存在(3.73%, p < 0.05),而超重白人未观察到此现象(0.68%, p = 0.7)。
结论:超重和肥胖的非洲裔美国儿童和西班牙裔美国儿童的FEV1/FVC显著降低,而该现象仅在肥胖的白人儿童中观察到。这些结果显示,与白人儿童相比,少数民族儿童的体重轻微增加,伴随着下气道梗阻的肺功能检测值的下降。由于非洲裔美国人和西班牙裔美国人中超重和肥胖的发病率较高,我们研究结果为这些少数民族儿童哮喘发病率较高提供了一个解释。

Abstract
BACKGROUND:Overweight, obesity, and asthma are more prevalent in minority children; yet, the association of overweight and obesity with spirometric values in asthmatic minorities is not well characterized.
OBJECTIVE: To study the relationship between weight, ethnicity, and spirometric values in children referred for asthma evaluation to a large inner-city hospital in Bronx, NY.
METHODS:Retrospective review of spirometry done at the first pulmonary clinic visit of 980 asthmatic children, aged 7-20 years, was conducted. Linear regression analysis was performed to elucidate the association of overweight and obesity with pulmonary function among Whites, African Americans, and Hispanics compared with their normal weight counterparts.
RESULTS:More African Americans (58%) and Hispanics (65.4%) were overweight and obese than Whites (51.2%) (p < .05). Compared with their normal weight counterparts, percent forced expiratory volume in the 1st second (FEV(1))/forced vital capacity (FVC) ratio was lower in both overweight and obese African Americans (2.99%, p < .05 and 3.56%, p < .01, respectively) and Hispanics (2.64%, p < .05 and 2.36%, p < .05, respectively); these differences were found in obese (3.73%, p < .05) but not in overweight (0.68%, p = .7) Whites.
CONCLUSIONS: FEV(1)/FVC ratio was lower in both overweight and obese African American and Hispanic children, while this association was present only among obese Whites compared with their normal weight counterparts. These results suggest that spirometric measures of lower airway obstruction decrease with smaller weight increments in minority children when compared with White children. In the context of the higher prevalence of overweight and obesity among African Americans and Hispanics, our findings offer one potential explanation for increased asthma among minority children.
