- Sought: genetic and environmental causes of birth defects.
Most birth defects cannot be prevented because their causes are not known. However, women can take a number of steps before and during pregnancy to reduce their risk [link to Birth Defects fact sheet]. These steps include taking a multivitamin containing 400 micrograms of folic acid daily starting before pregnancy and in early pregnancy. This helps to prevent serious birth defects of the brain and spinal cord, including spina bifida, and may also help prevent heart defects.
