| Résumé : | [BDSP. Notice produite par INIST KR0xkm2v. Diffusion soumise à autorisation]. Background A population-based study on prevalence of cerebral palsy in multiple births has not been carried out in China. The purpose of this paper was to determine the prevalence of cerebral palsy in multiple births and to explore the influence of multiple pregnancy on cerebral palsy after controlling for birthweight. Methods A cross-sectional study of cerebral palsy was carried out among 388 192 children aged<7 years in seven cities of Jiangsu province in China. Information about birthweight and plurality was obtained from routine health care records. Pediatricians at city level diagnosed all cases. All the doctors involved had taken part in a training programme held by Beijing Medical University. Stratified analysis by birthweight and its standard normal deviate was employed to compare the prevalence of cerebral palsy in multiples and singletons. Results The prevalence of cerebral palsy for children aged<7 years in multiples was 9.7 per 1000 children (95% confidence interval [CI] : 6.5-14.0), which was 6.5 times that in singletons (95% CI : 4.4-9.3). The overall neonatal mortality rate was 60.9 per 1000 liveborn multiples, being highest (944.4 per 1000) in the 500-999 g birthweight groups. Most liveborn multiples weighing<1500 g at birth probably died from diseases related to very low birthweight prior to this study. (...) |
