中老年职工心肺功能评价及其与工作能力的关系

Study on Cardiorespiratory Capacity of Aged Workers And Its Relation With Work Ability

本研究测量了162名来自不同行业中老年职工的心肺功能状态，年龄在40～60岁，其中男性110名，女性52名。结果发现心肺功能有着明显的性别差异，女性心肺功能指标的平均水平仅为男性的73％～78％。40～49岁年龄组职工的FVC％平均水平显著高于50～60岁组（P＜0．05）。提示随年龄增加FVC％下降，不同劳动类型间心肺功能的平均水平差异无显著意义（P＞0．05）。相关分析表明，心肺功能各测定指标与WAI间的相关性较低，心肺功能指标与WAI交叉分级间的关系也缺乏有统计学意义的联系，本文对其可能的原因进行了讨论。

In this study,the cardiorespiratory capacity of 162 aged workers (aged from 40 to 60),including 110 men and 52 women from various occupations was measured and the relation ship between cardiorespiratory capacity and work ability was evaluated. Work ability was estimated by work ability index (WAI). The results showed that a marked sex difference in cardiorespirory capacity was found. The mean levels of cardiorspiratory capacity of the women workers were about 73% to 78% of that of the men. The averaged FVC% for workers aged 40-49 years was significantly higher than that for workers aged 50- 60years (P< 0. 05 ),which suggested that the pulmonary ventilation function weaken with age. There were nosignificantly differences of cardiorespatory capacity in different work types. The resultsfrom correlation analysis Indicated a poor relation existed between cardiorespitatory capacity and WAI.
