早产儿是围产儿死亡的主要原因,存活者80％易发生疾病,易出现呼吸窘迫、支气管炎、肺发育不良、动脉导管未闭及免疫功能不完善等并发症。因此,预防早产一直是围产医学研究的课题,但早产病因目前尚不完全了解,尚需从多方面着手进行研究。运用圆形分布法探讨疾病发生规律,已在许多疾病病因探讨中应用,但在早产中尚未见报道,为了探讨早产儿发生的原因及发生时间规律,本文分析了西宁地区1996年-2001年间在青海医学院附属医院出生新生儿的全部资料,旨在发现早产儿发生的时间规律,现报告如下。
Premature babies are the major cause of perinatal death. 80% of the survivors are prone to the disease and are prone to respiratory distress, bronchitis, lung dysplasia, patent ductus arteriosus, and complications such as imperfect immune function. Therefore, the prevention of premature birth has been the topic of perinatal medical research, but the cause of premature birth is not yet fully understood, still need to proceed from many aspects of research. The use of circular distribution to explore the law of disease has been used in many etiological studies, but it has not been reported in preterm birth. In order to investigate the causes of premature infants and the timing of their occurrence, this paper analyzes the prevalence of premature infants in Xining from 1996 to 2001 Qinghai Medical College Hospital, all the information on newborns born to see the timing of preterm children found, are as follows.
