The livebirth prevalence of infantile simple hydrocephalus (IH) was investigated in a Swedish population-based survey. The study comprised all liveborn infants with IH apparent before the age of one year and born in the study area between 1967-82. A total of 202 infants fulfilled these criteria; of these, 141 (70%) were born at term and 61 (30%) were preterm. The mean prevalence was 0.53 per 1,000, with a slightly increasing trend from 0.48 in 1967-70 to 0.63 in 1979-82. The increase was entirely referable to the preterm group, in which the prevalence rose from 0.13 per 1,000 in 1967-70 to 0.30 in 1979-82. There was no tendency to an increase in the term group. In 12 of 23 children born very preterm the origin of the IH was a diagnosed cerebral haemorrhage. This is compatible with the increased risk of the latter condition that has been found in very preterm newborns. The mortality among children with IH was highest before the age of one year (15%), after which it was 1.2% per year.
在一项基于瑞典人群的调查中，对婴儿单纯性脑积水（IH）的活产患病率进行了研究。该研究纳入了1967年至1982年在研究区域出生、一岁前出现明显IH的所有活产婴儿。共有202名婴儿符合这些标准；其中，141名（70%）为足月儿，61名（30%）为早产儿。平均患病率为每1000人中有0.53例，从1967年至1970年的0.48略有上升至1979年至1982年的0.63。这种上升完全归因于早产组，其患病率从1967年至1970年的每1000人中有0.13例升至1979年至1982年的0.30例。足月儿组没有上升趋势。在23名极早产儿中，有12名的IH病因是诊断出的脑出血。这与在极早产儿中发现的后者患病风险增加是一致的。IH患儿的死亡率在一岁前最高（15%），之后每年为1.2%。
