Spina bifida epidemiology and demographics

Introduction

Overview

Overview

The incidence of spina bifida is approximately 3.5 per 10,000 live births per year in the U.S. The prevalence of spina bifida is approximately 187 to 890 per 100,000 live births. Before 1960, the case-mortality rate of all forms of spina bifida was 90% to 88%. Now the mortality rate is approximately is 10.1%. The overall ventriculoperitoneal shunt requirement rate is 33.8%. The paraplegia rate is 30.7%. The neurogenic bladder rate is 51.6%. The infection rate is 6.4% after the surgical procedure. Spina bifida is more commonly observed among preterm newborns. Spina bifida usually affects individuals of the Malays and Chinese and Indians race. Female are more commonly affected by than male. The male\male+female ratio is approximately 42%.
