General knowledge of _ related to young man's hypertension of Swedish expert's premature delivery
Swedish scientific research personnel think after analyzing the male health records of about 330,000 Sweden, premature delivery will lead to the fact the boy baby has a bit high blood pressure after growing into the youth, but this conclusion is suitable for women's remaining to study yet.
Some previous research reveal, it has relation high instead of blood pressure after growing up that the baby is underweight when being born in. In order to deepen the research in this respect, researcher Stevan and Johansson,et al. of Stockholm and Caroline medical college, having analyzed about 330,000 Swedish man's conscription health records at the age of 20, the research object was born during the period from 1973 to 1981.
Swedish researchers say, the foetus was usually born in gestation from 37 weeks to 40 weeks, is earlier than this period the birth is considered to be premature delivery. Separately through from 33 week to 36 week, 29 week until gestation was born from 32 week, 24 week to 28 week foetus, can be regarded as separately slight premature delivery, serious premature delivery and very serious premature delivery.
Johansson,et al. says in the medical magazine of latest American heart " circulates", their analysis result reveals, the boy baby of the slight premature delivery group is after grow into the youth, the intersection of heart and systolic pressure higher incidence 25% among the they, proportion this can rise in the colony in serious the intersection of premature delivery and group and very serious the intersection of premature delivery and young man of group, especially in very serious young man of premature delivery, heart the intersection of systolic pressure and higher incidence up to 93%. In addition, study, find slight premature delivery in the young man of group, too can increase risk to suffer from hypertension its while being underweight born, still; The shorter time they stayed in the mother's womb, its diastolic pressure of heart is the higher after growing up.
The reason pregnant time relates with blood pressure that Swedish researchers are not clear, but Johansson thinks, perhaps this relates to the fact that it is different from ordinary person that early newborn baby's blood vessel structure and hormone are secreted.
