煤炭企业工人认知功能的影响因素

The influencing factors of cognitive function in coal workers

目的探讨煤炭企业工人认知功能的影响因素。方法对某煤炭企业3205例工人进行健康检查，检查内容包括身高、体质量、血压、血常规、尿常规等，并运用简易精神状况检查表（MMSE）评价其认知功能。根据MMSE评分分为认知功能障碍组（84例）和认知功能正常组（3121例）。运用Logistic回归分析探究影响认知功能的因素。结果煤炭企业工人认知功能障碍的患病率为2．62％；认知功能障碍组年龄[（47．27±8．24）岁]显著高于认知功能正常组[（41．39±8．65）岁]（P〈0．05）、文化程度显著低于认知功能正常组（χ2=46．610，P〈0．01）；认知功能障碍组低密度脂蛋白胆固醇[（2．72±0．65）mmol/L]、尿pH（5．54±1．51）上显著低于认知功能正常组[（2．89±0．73）mmol／L、（5．92±1．28）]（P〈0．05）。Logistic回归分析显示，年龄、文化程度、BMI、低密度脂蛋白胆固醇、尿pH为认知功能障碍的影响因素。结论认知功能障碍受到年龄、文化程度、BMI、低密度脂蛋白胆固醇、尿pH的影响，年龄越大，文化程度、BMI、低密度脂蛋白胆固醇、尿PH越低，越容易出现认知功能障碍。

Objective To explore the influencing factors of coal workers＂ cognitive function. Meth- ods There was a physical examination on 3 205 workers in the coal mine enterprise.The physical examina- tion included height ,weight, blood pressure, blood routine examination and routine urine test, and Mini Men- tal State Examination （MMSE） was used to evaluate the cognitive function.The coal workers were divided in- to cognitive dysfunction group （84 cases） and cognitive function normal group （3 121 cases） according to MMSE scores.Logistic regression analysis was used to explore the influencing factors of cognitive function. Results The prevalence of cognitive dysfunction was 2.62% in coal workers.The age of the cognitive dys- function group（47.27±8.24） was significantly higher than that in the cognitive function normal group （41.39±8.65） （P〈0.05） ,and the degree of culture in cognitive dysfunction group was significantly lower than those in the cognitive function normal group （χ2 = 46.610, P〈 0.01 ）. The low density lipoprotein cholesterol （（2.72±0.65）mmol/L） , urine pH（ 5.54± 1.51 ） in the cognitive dysfunction group were significantly lower than those in the cognitive function normal group （ （ 2.89±0.73 ） retool/L, （ 5.92±1.28 ） ） （P〈 0.05 ）. The lo- gistic regression analysis showed that age, culture level, BMI, low density lipoprotein cholesterol, urine pH were the impacting factors of cognitive dysfunction. Conclusion Cognitive dysfunction is influenced by age, culture level, BMI and low density lipoproteiu cholesterol. The higher of the age and the lower of the culture level, BMl,low density lipoprotein cholesterol, urine pH, the more vulnerable to cognitive dysfunction.
