近年来,我国早产儿发生率有所上升,有关资料显示,我国包括早产儿在内的低出生体重儿出生率为4.75%～8.51%。其原因除了疾病和遗传等因素外,还受到社会、经济环境和人们生育观念变化的影响,如近年来生育年龄的推迟造成高龄产妇的增加、人工受精和人工流产的增多、孕妇在孕期生活和工作压力加大以及环境所导致的意外因素等。应当引起关注。
In recent years, the incidence of premature infants in our country has risen. The data show that the birth rate of low birth weight infants, including premature infants, is 4.75% ~ 8.51%. In addition to the factors such as diseases and heredity, the reasons are also influenced by social and economic conditions and changes in people’s concept of birth. For example, the postponement of childbearing age in recent years has resulted in the increase of older mothers, the increase of artificial insemination and induced abortion, the increase of pregnant women during pregnancy and Work pressure and the environment caused by unexpected factors. Should cause concern.
