The Centers for Disease Control and Kaiser Permanente queried 17,000 men and women to determine how many endured abuse as children. The population studied was representative of the United States population as a whole. More than one out of four women (28%) and approximately one of six men (16%) said they were sexually abused during childhood. More than one out of four (28%) said they were physically abused as children which the researchers defined as being hit hard enough to receive injuries. More than one out ten adults said they were emotionally abused (11%) as children. Thirteen percent grew up in homes where their mothers were treated violently. With respect to neglect, 10% were denied the basic necessities of life (food, clothing, shelter, etc.) and 15% were emotionally neglected in that they grew up in homes where their parents or other caretakers never expressed affection to them.
