Researchers have made a connection between childhood abuse suffered by African-American women and asthma which develops later in their lives. As part of the Black Women’s Health Study at the Slone Epidemiology Center at Boston University, conducted from 1995 to 2011, a total of 28,456 women gave information on physical and sexual abuse suffered before age 11, as well as between the ages of 12 and 18. The study found that an African-American woman who suffered abuse as a child saw her chances of developing asthma later in life increase 20 percent. The link between physical abuse and asthma was stronger than that seen between sexual abuse and asthma, researchers said. Physical abuse includes actions intended to injure a child, while sexual abuse includes actions intended for the gratification of the abuser.
