摘要
目的 探讨化工工人脑力功能状况及其影响因素。方法 采用系统抽样的方法抽取10 1名化工职工,对其进行脑力功能测定:短时记忆能力、译码能力、脑力作业能力(AYP)指数和脑力功能指数(MFI)。结果 化工工人脑力功能呈近似正态分布;不同年龄化工工人脑力功能明显不同,>4 0岁年龄组脑力功能各项指标均低于≤4 0岁年龄组(P<0 .0 1) ;随着文化程度的提高,化工工人脑力功能各项指标均逐渐增加(P<0 .0 1) ;不同劳动类型中,各指标均为脑力劳动者最高,体力劳动者最低,但仅MFI差异有统计学意义(P<0 .0 5 ) ;女性职工各项指标均高于男性职工,除短时记忆外,差异具有统计学意义(P<0 .0 1) ;脑力功能与年龄呈显著的负相关关系,与文化程度呈显著的正相关关系(P<0 .0 1)。结论 增强化工劳动者文化素质是提高其脑力功能并进而促进其工作能力的一个重要途径。
Objective To study the mental capacity and its influential factors among workers in chemical industry system(CIS). Methods One hundred and one workers were selected from CIS by systematic sampling. Then their mental capacity was measured using 4 indices: short-time memory, decode, AYP and mental functional index (MFI). Results Normality test revealed that the data of CIS workers' mental capacity displayed a profile approximate to normal distribution. All the levels of the four indices measured in the CIS workers aged more than 40 years were lower than those in workers aged less than 40 years (P<0.01). All the levels of indices gradually increased with the increase of educational level (P<0.01). Among the workers doing different types of work, the mental workers had the highest level in all indices while physical workers had the lowest level, but only the difference in respect to MFI was significant (P<0.05). Female CIS workers had higher level in all indices than male; the differences were significant except that in short-time memory (P<0.01). Mental capacity was noted to have significantly negative correlation with age and significantly positive correlation with educational level (P<0 01). Conclusion Increasing CIS workers' educational level is a very important approach to the improvement of their mental capacity and hence the upgrading of their work ability.
