综合指数与粗糙集联用法在评价人群血常规指标健康风险水平的应用

目的应用综合指数与粗糙集理论联用法评价人群血常规指标,为评价相关指标健康风险状况提供参考依据。方法回顾性分析2016-2020年广东地区送往广州达安临床检验中心的20023份血常规标本检验数据,建立指数分析(综合指数)与风险分析(粗糙集理论)联用法评价人群血常规8项指标健康水平,即红细胞计数(RBC)、平均红细胞容积(MCV)、血红蛋白(Hb)、平均红细胞血红蛋白量(MCH)、平均红细胞血红蛋白浓度(MCHC)、血细胞比容(HCT)、白细胞计数(WBC)和血小板计数(PLT)。结果广东整体人群血液健康指数(BHI)均值为0.774,其中老年人群为0.742、男性人群为0.758、非老年人群为0.794、女性人群为0.790。2016-2019年各类人群BHI值均表现为逐渐降低,2020年略有上升。在单项指标中,MCHC的健康指数(1.280~1.398)和MCV的健康指数(0.834~1.010)均明显高于其他指标。风险分析提示MCHC在各类人群中均存在较高风险,风险覆盖度分别为整体人群9.362‰、男性人群13.242‰、女性人群20.831‰、老年人群5.579‰和非老年人群7.547‰。结论综合指数与粗糙集理论联用法可以评价人群血常规指标健康风险状况,2016-2020年广东地区人群血常规健康程度为合格水平且表现为总体上升,MCHC和MCV指标对广东地区人血常规健康影响较大,同时在各类人群中MCHC指标均提示不同概率的风险,应加强监测。

Application of the combined method of composite index and rough set in evaluating the healthy and risky level of population blood routine indicators

Objective To evaluate the blood routine indicators of population by the combined method of composite index and rough set theory,and to provide reference basis for evaluating the health risk status of related indicators.Methods The test data of 20023 blood routine specimens sent to Guangzhou Da′an clinical laboratory center from 2016 to 2020 were analyzed retrospectively.The combined method of index analysis(composite index)and risk analysis(rough set theory)was established to evaluate the health level of 8 blood routine indicators,namely red blood cell count(RBC),mean corpuscular volume(MCV),hemoglobin(Hb),mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC),hematocrit(HCT),white blood cell count(WBC)and platelet count(PLT).Results The average blood health index(BHI)of the whole population in Guangdong was 0.774,including 0.742 for the elderly,0.758 for men,0.794 for non elderly and 0.790 for women.From 2016 to 2019,the BHI values of each population decreased gradually,and increased slightly in 2020.Among the single indicators,the health index of MCHC(1.280-1.398)and MCV(0.834-1.010)were significantly higher than the others.The risk analysis indicated that MCHC had a higher risk in all kinds of people.The risk coverage was 9.362‰for the whole population,13.242‰for the male population,20.831‰for the female population,5.579‰for the elderly and 7.547‰for the non-elderly population.Conclusion The combined method of composite index and rough set theory can evaluate the health risk status of blood routine indicators.From 2016 to 2020,the blood routine health of the population in Guangdong is at a qualified level and shows an overall increase.MCHC and MCV indicators have a great impact on the blood routine health of people in Guangdong.At the same time,MCHC indicators in all kinds of people suggest risks with different probabilities,so monitoring should be strengthened.
