[Epidemiological study of cerebral palsy in Shiga Prefecture, Japan, during 1977-2000. Part 1: incidence pattern of cerebral palsy in Shiga Prefecture with reference to birth weight and gestational age].
The prevalences of cerebral palsy (CP) among 6-year-old children in Shiga Prefecture born during 1977-2000 were compared in eight successive 3-year periods (period I-VIII) with reference to birth weight and gestational age. During the 24-year surveillance period, among 349,514 children born in Shiga Prefecture, 569 children had CP at the age of 6 years, thus the prevalence was 1.63 per 1000 live births. The prevalence increased significantly in period V compared to previous periods. There were no significant differences among period V-VIII. The proportion of CP with low birth weight and lower gestational age increased progressively, and two-thirds of CP in the period VIII had a LBW and/or preterm gestation.
