Quantitative study on relation between IAA and EHT

  Objective   To discuss the relationship between IAA and EHT and discover its mechanism.

  Methods   Fifty-eight patients of EHT were randomly selected from 600 teachers under 60 years old in primary and middle schools in BeiPiao city as case group, 33 teachers were randomly sampled as control group from the same crowd with no hyper tension, no liver or nephritic diseases, no diabetes.Then the content of IAA in the two groups was measur ed with quantitative method.The statistic methods were χ²-test and noncondition-Logistic analysis.

  Results   IAA of EHT group was apparently higher than that of control, they were 10.34%, 44.83%, 44.83% in EHT group.That in control group were 33.33%, 48.49% and 18.18%.There was significant difference proved by χ²-test(P < 0.05).There was dose-reaction relationship between IAA and EHT.By noncondition-Logistic analysis, family history, IN and IAA were involved in the model.

  Conclusion   There was a relationship between IAA and EHT.IAA was likely an independent risk factor of EHT.
