采用分层整群抽样方法，选取安徽省３ 个自然地理区域７ 个县所辖２０ 个乡镇的５０７１４ 名１ ～８ 岁儿童进行脑瘫调查。结果显示，安徽省农村地区１ ～８ 岁儿童脑瘫患病率为２－０７ ‰，不同性别和不同年龄组脑瘫患病率均无显著性差异，但３ 个地区儿童脑瘫患病率呈显著性差异，以淮北地区最低（１－２８ ‰） ，皖南地区最高（３－３４ ‰） ，江淮地区居中（２－０９ ‰） 。其地区差的原因尚待进一步研究
A stratified cluster sampling method was used to select 50714 children aged 1 ~ 8 years old from 20 townships in 7 counties in 3 natural geographical regions of Anhui Province for cerebral palsy investigation. The results showed that the prevalence of cerebral palsy in children aged 1 ~ 8 in rural areas of Anhui Province was 2 ~ 07 ‰, and there was no significant difference in the prevalence of cerebral palsy among different sexes and different age groups, but the prevalence of cerebral palsy in 3 districts was significantly The difference was lowest in Huaibei (1-28 ‰), highest in Southern Anhui (3-34 ‰), and moderate in Jianghuai (2-09 ‰). The reason for the poor area remains to be further studied
