WHO: Third of women suffer domestic violence

For domestic violence figures, scientists analyzed information from 86 countries focusing on women and teens over the age of 15. They also assessed studies from 56 countries on sexual violence by someone other than a partner, though they had no data from the Middle East. WHO experts then used modeling techniques to come up with global estimates for the percentage of women who are victims of violence.

Accurate numbers on women and violence are notoriously hard to pin down. A US government survey reported almost two years ago that 1 in 4 American women said they were violently attacked by their husbands or boyfriends, and 1 in 5 said they were victims of rape or attempted rape, with about half those cases involving intimate partners.

Some experts thought the rape estimate was extremely high but said it may have to do with the definition of assault. The results were from a survey that did not document the claims, which were made anonymously.

In a related paper published Thursday online in the journal Lancet, researchers found more than 38 percent of slain women are killed by a former or current partner, six times higher than the rate of men killed by their partners.

Heidi Stoeckl, one of the authors at the London School of Hygiene and Tropical Medicine, said the figures were probably an underestimate. She and colleagues found that worldwide, a woman's highest risk of murder was from a current or ex-partner.

In countries like India, Stoeckl said "honor killings," where women are sometimes murdered over dowry disputes or perceived offenses like infidelity to protect the family's reputation, add to the problem.

She also noted that women and men are often slain by their partners for different reasons.

"When a woman kills her male partner, it's usually out of self-defense because she has been abused," she said. "But when a woman is killed, it's often after she has left the relationship and the man is killing her out of jealousy or rage."

Stoeckl said criminal justice authorities should intervene sooner.

"When a woman is killed by a partner, she has often already had contact with the police," she said.

Stoeckl said there should be more protection for women from their partners, particularly in cases where there is a history of violence.

"There are enough signs that we should be watching out for that," she said. "We certainly should know if someone is potentially lethal and be able to do something about it."
