Objective: To investigate the prevalence and type distribution of childhood cerebral palsy (CP) in China.  

Method: A cross sectional survey was carried out among 1047327 children aged 1-6 years old in Heilongjiang, Hebei, Gansu, Jiangsu, Guangxi, and Sichuan provinces of China during May 1997 ¨C December 1998.

Results: The crude prevalence of CP for children aged 1-6 years old was 1.92 per thousand (95% CI£¬1.84¡ë-2.00¡ë); In addition, prevalence of CP were also reported for factors such as sex (2.24¡ë in male and 1.55¡ë in female), age (over 2.2¡ë among children younger than 3 years old and below 2.0¡ë among the olders), ethic group(1.95¡ë in Han and 1.32¡ë in the Minorities), birth weight, gestational age (35.1¡ë in premature ), and area. As the type distribution, the spasticity is the most (53.6%), then the atonia (13.4%), the ataxia (10.0%), the athetosis (4.6%), the tremor (0.9%),the rigidity (0.6%), and the mixed (12.4%).

Conclusion: Prevalence in China is at the low range among the world, which may be due to low prevalence and low survival rate of premature newborn in China. The prevalence and type distribution are associated with areas, sexes, ages, ethnic groups, birth weights, and gestational ages.
