Childhood Abuse Linked to Diabetes Risk in Adult Women

Women who were victims of childhood abuse may be at increased risk of developing diabetes in adulthood, new findings suggest. Researchers surveyed 67,853 U.S. nurses and found that 54 percent reported physical abuse and 34 percent reported sexual abuse before age 18. Moderate and severe physical and sexual abuse were associated with a 26 percent to 69 percent increased risk of type 2 diabetes in adulthood. "Much, although not all, of this association is explained by the greater weight gain of girls with a history of abuse.

The weight gain seems to start in teenage years and continues into adulthood, increasing the risk of diabetes," lead author Janet Rich-Edwards, director of developmental epidemiology at Connors Center for Women's Health and Gender Biology, Brigham and Women's Hospital in Boston, said in a Center for Advancing Health news release. But she added that weight gain explained only 60 percent of the association, "implying that the experience of abuse gets incorporated into the body through other mechanisms, as well." Further research is needed to understand the link between childhood abuse and diabetes, the study author added.

"One theory is that abused women develop disordered eating habits as a compensatory stress behavior, leading to excess weight gain," Rich-Edwards said. "Another theory suggests that child abuse may increase levels of stress hormones that later cause weight gain and insulin resistance, characteristic of diabetes." The study appears online and in the December print issue of the American Journal of Preventive Medicine. "Child abuse can leave an enduring imprint on health in adulthood," Rich-Edwards said in the news release. "We hope to alert clinicians to the possible role of abuse in the histories of some patients that they see with pre-diabetes and diabetes. We also need to help families prevent child abuse, and we need to learn the best ways to reduce the long-term health burden that it imposes."

New CPR Guidelines Emphasize Compressions First

Don't fret about mouth-to-mouth. The average, untrained person can still save a life by focusing on chest compressions first, say new guidelines from the American Heart Association. The simplified form of cardiopulmonary resuscitation, or CPR, focuses on giving chest compressions to keep the blood and the oxygen in the blood flowing to the heart and brain. The group's advice comes on the heels of studies in the past year trumpeting that a compression-only approach is as good or better than compression plus mouth-to-mouth. It updates guidelines from 2005.

"For a variety of reasons, when someone suddenly collapses in cardiac arrest, people often don't start any type of CPR, and one of the barriers, we believe, is that people think it's fairly complicated to do CPR," explained Dr. Michael Sayre, co-author of the new guidelines and chairman of the American Heart Association's emergency cardiovascular care committee. "But chest compressions alone are easy, and anyone can do it," he said. "Chest compressions actually act like an artificial heart, pumping blood to the heart and brain," Sayre noted. "And, that blood often will have a reserve of oxygen."

The American Heart Association recommends that if an adult is unresponsive and not breathing or is having occasional unusual breaths that sound like gasping, any bystander should first call 911 and then begin chest compressions. If someone else is nearby, send that person in search of an automatic external defibrillator, a device that can shock the heart back into normal rhythm. "To give the victim the best chance of survival, three actions must occur within the first moments of a cardiac arrest: activation of the EMS system, provision of CPR and operation of a defibrillator," the new guidelines state.
