西安地区人群肺功能问卷调查

Questionnaire survey on pulmonary function test in Xi＇an

目的探讨西安地区部分人群肺功能的特点，生活习惯和环境等因素与肺功能的关系。方法2012年7—8月对西安地区东郊和北郊共405人进行问卷调查和肺功能检测，并用多元逐步回归分析不同因素对肺功能指标的影响。结果西安地区东郊和北郊人群FVC，PEF和FEF25—75均低于正常预计值，东郊和北郊人群之间肺功能主要指标差异有统计学意义（P〈0．001）；肺功能主要指标与年龄增长、性别和肺部疾病呈负相关（P〈0．05）。结论西安地区部分人群肺功能主要指标偏低，为今后该地区呼吸系统疾病防治提供依据。
