英语翻译
Obesity is becoming a social and economical problem in the Western World for the numerous respiratory,cardiovascular and metabolic diseases associated with the increase in body mass.1,2 Whereas most of the organs or systems of the body slowly react to obesity,the respiratory system quickly adapts by reducing lung volumes and airway caliber.3–5 As a result,gas exchange worsens,6 and dynamic compression of the airways downstream from the flow limiting segments occurs,7 thus explaining symptoms and exercise limitation complained by obese individuals even when their spirometry is still normal or near normal.Few longitudinal studies have consistently shown that obesity is associated with higher lung function decline.8–12 Thus,obesity may alter lung function not only by reducing lung volume and airway caliber but also by accelerating the decline in lung function.However,to our knowledge,scanty information is available about the effects of changes in obesity status on lung function decline.The availability of existing longitudinal data from an epidemiological population- based study carried out in 1980s gave us the opportunity to explore this possible association of current respiratory interest.This study aimed to evaluate in a general population whether changes in obesity status may accelerate or slow down the decline in lung function over an 8-year follow-up.

肥胖正在成为一个社会和经济问题,在西方世界的许多呼吸,心血管和代谢性疾病与增加体重.1,而大多数的器官或系统的身体慢慢地作出反应,肥胖,呼吸系统迅速适应减少肺容积和气道口径.3–5结果,气体交换恶化,6和动态压缩的航空公司从下游的流量限制部分发生,7从而解释症状和行使限制抱怨的肥胖者甚至在他们的肺功能仍正常或接近正常.几个纵向研究一贯表明,肥胖是有较高的肺功能下降.8–12因此,肥胖可以改变肺功能不仅通过减少肺容积和气道口径也加速下降,肺功能.然而,据我们所知,很少有关于信息变化的影响肥胖对肺功能下降.利用现有的纵向数据从流行病学人口为基础进行的研究在20世纪80年代使我们有机会探讨这一可能的协会目前的呼吸的兴趣.本研究的目的是评估在一般人口的变化是否在肥胖状况可能加快或减缓肺功能下降超过了8年随访.
