对４３６例中老年职工（４０～６０岁）的工作能力（ＷＡＩ）进行了定量分析，研究对象分为脑力劳动、体力劳动和体脑混合３种劳动类型，将ＷＡＩ分为好、中、差３个等级．分析结果表明：男女职工ＷＡＩ均随年龄增加而明显下降，女性平均水平高于男性（Ｐ＜０．０５）；体力劳动者ＷＡＩ平均水平最低，男女分别为３１．７和３３．０，而脑力劳动者最高，男女均为３８．８，劳动类型间的差异有显著意义（Ｐ＜０．０１）．
The work ability (WAI) of 436 middle-aged and elderly workers (40-60 years old) was quantitatively analyzed. The subjects were divided into three types of labor: mental workout, physical workout and brain-brain mixing. The WAI was divided into good, moderate and poor 3 levels. The results showed that the WAI of both male and female workers decreased significantly with the increase of age, the average level of female was higher than that of male (P <0.05); the average level of WAI of manual workers was the lowest (31.7 and 33.0 respectively) The highest number of workers, both men and women were 38.8, the type of labor was significantly different (P <0.01).
