摘要
为探索中老年职工肺功能与工作能力的关系，采用现场调查法对成都地区２８５名不同职业的中老年职工进行肺功能〔用力肺活量（ＦＶＣ）、一秒钟用力呼气容积（ＦＥＶ１）、一秒率（ＦＥＶ１％）、用力呼气中段平均流量（ＭＭＥＦ），将前三项指标等级化值之和得肺功能指数（ＰＦＩ）〕和工作能力指数（ＷＡＩ）测量。结果显示，ＦＶＣ、ＦＥＶ１％在劳动类型间均具显著性差异（Ｐ＜０．０５），ＦＶＣ在性别间也有显著性差异（Ｐ＜０．０５）。ＦＥＶ１％、ＭＭＥＦ分别和ＷＡＩ有显著的相关关系（Ｐ＜０．０５）；而ＦＶＣ、ＦＥＶ１与ＷＡＩ的关系不明显（Ｐ＞０．０５）。同时，ＰＦＩ与ＷＡＩ分级的一致率达４３．８％：完全不一致率为４．５６％。提示，ＦＥＶ１％、ＭＭＥＦ在中老年在职职工工作能力评价中可能具有潜在应用价值。
To explore the relationship between pulmonary function and work ability,a field study was conducted in 285 aging workers (aged 40 to 60) of different occupations in Chengdu area.The pulmonary function indices included FVC,FEV 1,FEV 1%,MMEF,and the pulmonary function index (PFI) which was the sum of the rating values from the first three indices.The work ability index (WAI) was also measured.Between work types,the indices,including FVC and FEV 1%,showed significant difference( P <0 05);FVC also showed significant difference between male and female workers( P <0 05) There was a significant relationship between PFI (including FEV 1% and MMEF) and WAI( P <0 05), but the relationship between FVC(or FEV 1) and WAI was not statistically significant ( P >0 05) Moreover,the agreement percentage between the classifications of PFI and WAI was 43.8%;the disagreement percentage was 4.56%.The results suggest that FEV 1% and MMEF may be beneficial to the objective evaluation of the work ability of aging workers
