Pediatricians warn of long-term harms of spanking

The nation's leading pediatricians' group has strengthened its advice against spanking and other physical punishment because of the potential for long-term harm.

In an updated policy released Monday, the American Academy of Pediatrics says that can include aggression, brain changes, substance abuse and suicidal behavior in adulthood.

The academy says research since its 1998 discipline policy led to the update. It says spanking is falling out of favor among parents, especially those with young children. While some parents still believe it can lead to short-term improvements in behavior, studies show spanking is no more effective than non-physical punishment, including timeouts, setting firm limits and establishing unwanted consequences.

"The good news is, fewer parents support the use of spanking than they did in the past," Robert D. Sege, MD, PhD, and a past member of AAP Committee on Child Abuse and Neglect, an author of the policy statement, said in a statement. "Yet corporal punishment remains legal in many states, despite evidence that it harms kids – not only physically and mentally, but in how they perform at school and how they interact with other children."

The group also suggests putting favorite toys away or reducing screen time.

"Although many children who were spanked become happy, healthy adults, current evidence suggests that spanking is not necessary and may result in long-term harm" the academy advises.

Studies published in the past two decades have bolstered evidence that spanking can make young kids more aggressive and defiant.

Other studies have linked physical punishment in childhood with later brain changes in young adults including reduced gray matter and elevated levels of stress hormones. Suicidal behavior, substance abuse and anger are among other potential long-term consequences of spanking, studies have suggested.

The academy also warns against harsh verbal abuse including shaming kids, citing research linking it with depression and behavior problems in teens.

AAP's policy statement provides resources for both physicians and parents to learn healthy forms of discipline, including limit setting, redirecting, and setting expectations.

"There's no benefit to spanking," Sege said. "We know that children grow and develop better with positive role modeling and by setting healthy limits. We can do better."
