“…Research has shown a higher incidence of infant morbidity in single mothers (Taffel, 1990), black mothers (Leland, Petersen, Braddock, & Alexander, 1995;Geronimus, 1987;Ingram, Makuc, & Kleinman, 1986;Kleinman, 1990;Taffel, 1990), low-income mothers (Brook, 1980;MacMahon, 1982;Stockwell, Swanson, & Wicks, 1988;Taffel, 1990), and high school dropouts (Kappelman, Khan, Washington, Stine, & Cornblath, 1974;Taffel, 1990). Maternal education has also been found to be related positively to MD prenatal care (Schaefer & Hughes, 1976;Taffel, 1990).…”
