To register the prevalence of cerebral palsy (CP) and determine etiological factors for the condition.
Population based study with registration of CP-cases in children born during the 30-year period 1970-99. Cases with postneonatal etiology were excluded.
166 CP-cases were registered among 70 824 children, a prevalence of 2.3 per 1000 live born infants. The prevalence did not change significantly during the period. 66 (40%) were low birthweight infants (LBWIs; <2500 g), and 100 (60%) normal birthweight infants (NBWIs; > or = 2500 g). The origin was classified as prenatal in 37 (22%), perinatal/neonatal in 78 (47%) and unclassifiable in 51 (31 %). In LBWIs 39/66 (59%) had a perinatal/neonatal etiology, most frequently intra- or periventricular hemorrhages (IVH/PVH) and/or periventricular leukomalacia (PVL) or cerebral infarctions (CI) (17; 44%). In NBWIs 39/100 (39%) had a perinatal etiology, most frequently hypoxic-ischemic encephalopathy (HIE) (31; 79%).
In a substantial percentage of CP-cases perinatal/neonatal brain injury was classified as the cause. Among these IVH/PVH/PVL/CI dominated in LBWIs, while HIE dominated in NBWIs. Our data may point to preventability of a larger part of CP than earlier suggested.
登记脑瘫(CP)的患病率并确定其病因。
基于人群的研究,登记1970 - 1999年30年间出生儿童中的CP病例。排除新生儿期后病因的病例。
在70824名儿童中登记了166例CP病例,每1000例活产婴儿中的患病率为2.3。在此期间患病率无显著变化。66例(40%)为低体重儿(LBWIs;<2500克),100例(60%)为正常体重儿(NBWIs;≥2500克)。病因分类为产前的有37例(22%),围产期/新生儿期的有78例(47%),无法分类的有51例(31%)。在低体重儿中,39/66例(59%)有围产期/新生儿期病因,最常见的是脑室内或脑室周围出血(IVH/PVH)和/或脑室周围白质软化(PVL)或脑梗死(CI)(17例;44%)。在正常体重儿中,39/100例(39%)有围产期病因,最常见的是缺氧缺血性脑病(HIE)(31例;79%)。
在相当比例的CP病例中,围产期/新生儿期脑损伤被归类为病因。其中,IVH/PVH/PVL/CI在低体重儿中占主导,而HIE在正常体重儿中占主导。我们的数据可能表明,CP的可预防性比之前认为的更大。
