Pregnancy complications in Sioux Indians.

The poor health status of Sioux Indians residing on reservations in South Dakota has been recognized for many years. The present report documents evidence of a high incidence of socioeconomic health-related disorders and pregnancy-related complications by comparing 342 pregnant white women and 405 pregnant Sioux Indian women. In collaboration with the Aberdeen Area Indian Health Service, beginning in 1976, a program was initiated to identify, assess risks, and provide patient management for pregnant Sioux Indians. This prenatal consultative program has proved effective in the reduction of fetal and infant mortality.
