【摘要】 目的:探讨孕产妇死亡病例空间分布理论概率模型。方法:采用Poisson分布和负二项分布对开江县1991～2005年孕产妇死亡病例空间分布进行拟合。结果:开江县孕产妇死亡病例的实际分布不服从Poisson分布(χ2=8.43,P<0.025),而服从于负二项分布(χ2=0.84,P>0.50)。结论:开江县孕产妇死亡病例在空间分布不是随机均匀的,而有严格的地区聚集性。引起这种聚集的原因,可能与当地医疗条件,孕产妇保健工作人员业务水平及孕产妇保健知识缺乏有关。更多还原

【Abstract】 Objective:Study of space distribution probability model of gravida and puerperant death cases.Methods:Fitting the Poisson distribution and the negative binomial distribution on gravida and puerperant death cases by space distribution in Kaijiang county 1991-2005 years.Results:Not accord with the Poisson distribution(χ2 =8.43,P<0.025),but accord with the negative binomial distribution (χ2=0.84, P>0.50) of reality distribution of gravida puerperabt death cases.Conclusion:Prove not random,but have strict gather area of gravida and puerperant death cases in Kaijiang county.This cause it is the rural area medical treatment equipment,gravida and puerperant health workers vocational standard,gravida and puerperant health knowledge deficiency have sth.更多还原
