The Adequacy of Prenatal Care Utilization Index (also known as the Kotelchuck Index) classifies prenatal care received by mothers into 1 of 4 categories: inadequate, intermediate, adequate, and adequate plus by combining information about the timing of prenatal care, the number of visits and the infant’s gestational age.  According to the Kotelchuck Index, the adequacy of prenatal care received varied by maternal race and ethnicity.  In 2000, 75.7 percent of white mothers received adequate or adequate plus prenatal care, compared to 67.1 percent of African-American mothers, 58.1 percent of Native American mothers, 73.9 percent of Asian or Pacific Islander mothers and 65.6 percent of Hispanic mothers.  In addition, African-American mothers were nearly twice as likely, and Native American mothers nearly 2 1/2 times as likely as white mothers to receive inadequate prenatal care (19.1 percent, 24.1 percent, and 10.4 percent, respectively).
