ABSTRACT

Objective To conduct the epidemiological investigation and analysis of cerebral palsy in Xinxiang of Henan Province and to investigate its risk factors in order to provid a basis for further study of etiology and prevention of cerebral palsy information.Methods Cluster sampling survey was carried out among children aged 1-6 years in XinXiang,Henan Province,and the data were analyzed by using SPSS 13.0 statistical analysis software.Results The morbidity of infantile cerebral palsy in Xinxiang of Henan Province was 2.82‰.The prevalence distribution in all age groups was 2.46 ‰-3.11‰(x2 =0.374,P =0.996),and the prevalence rate in male and female was significantly different(x2 =0.139,P =0.709) ; the sex ratio was 1.09 ∶ 1.00.Prevalence rate was slightly lower in urban areas than in rural areas (x2 =0.526,P =0.769).But no significant differences were observed in all of the data above.The incidence of cerebral palsy of children whose mothers did not established perinatal care manual and guidance during pregnancy was 5.86 times of the children whose mothers established perinatal care manual and guidance (x2 =116.806,P =0.000) ;the incidence of cerebral palsy in children whose mothers did not receive regular prenatal care during pregnancy was 5.37 times of the children whose mothers receive regular prenatal care during pregnancy (x2 =43.904,P =0.000);the incidence of cerebral palsy in children who had no neonatal follow-up after birth was 8.55times of the children with neonatal follow-up after birth (x2 =68.987,P =0.000).The incidence of cerebral palsy in children whose developmental disorders were not timely diagnosed and treated medically was 5.39 times the children whose developmental disorders were timely diagnosed and treated (x2 =56.003,P =0.000).The significant differences were observed in all of the data above.In the classification of cerebral palsy,the spastic type was the most (42.1％) ;followed by the dyskinetic (24.6％) ; the mixed (18.8％) ; and the ataxia(14.5％).Conclusions The survey results can reflect current prevalence of infantile cerebral palsy in children aged 1-6 years in XinXiang,and can be served as a basis for further prevention and treatment of cerebral palsy information.
