Third of women worldwide 'have been physically or sexually assaulted' In conjunction with the report, WHO issued guidelines for authorities to spot problems earlier and said all health workers should be trained to recognise when women may be at risk and how to respond appropriately. Globally, the WHO review found 30 per cent of women are affected by domestic or sexual violence by a partner. The report was based largely on studies from 1983 to 2010. According to the United Nations, more than 600 million women live in countries where domestic violence is not considered a crime. The rate of domestic violence against women was highest in Africa, the Middle East and southeast Asia, where 37 per cent of women experienced physical or sexual violence from a partner at some point in their lifetime. The rate was 30 per cent in Latin and South America and 23 per cent in North America. In Europe and Asia, it was 25 per cent. Some experts said screening for domestic violence should be added to all levels of health care, such as obstetric clinics. "It's unlikely that someone would walk into an ER and disclose they've been assaulted," said Sheila Sprague of McMaster University in Canada, who has researched domestic violence in women at orthopaedic clinics. She was not connected to the WHO report. "Over time, if women are coming into a fracture clinic or a prenatal clinic, they may tell you they are suffering abuse if you ask," she said. For domestic violence figures, scientists analysed information from 86 countries focusing on women 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 modelling techniques to fill in the gaps and to come up with global estimates for the percentage of women who are victims of violence. In a related paper published online in the journal Lancet, researchers found more than 38 per cent of slain women were 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 likely to be an underestimate. She and colleagues found that globally, a woman's highest risk of murder was from a current or ex-partner. Stoeckl said criminal justice authorities should intervene at an earlier stage. "When a woman is killed by a partner, she has often already had contact with the police," she said. Stoeckl said more protective measures should be in place for women from their partners, particularly when he or she has a history of violence and owns a gun. "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.
