Data have been obtained from a total population study of diagnosed Down's syndrome cases born in Queensland between 1976 and 1985. Survival curves show a survival rate to one year of 87.4% and no significant differences in such patterns over the two five year periods of the study. Survival curves comparing maternal age at birth, sex of the infant, and locality of birth also indicate that early death is unrelated to any of these factors. Congenital heart disease and respiratory infection are the most common causes of infant death.
数据来自对1976年至1985年间在昆士兰州出生的已确诊唐氏综合征病例的全人群研究。生存曲线显示,一岁时的生存率为87.4%,在该研究的两个五年期间,这种模式没有显著差异。比较出生时母亲年龄、婴儿性别和出生地的生存曲线也表明,早期死亡与这些因素中的任何一个都无关。先天性心脏病和呼吸道感染是婴儿死亡的最常见原因。
