The study is based on interviews with more than 24 000 women from rural and urban areas in 10 countries: Bangladesh, Brazil, Ethiopia, Japan, Namibia, Peru, Samoa, Serbia and Montenegro, Thailand, and the United Republic of Tanzania.
The study finds that one quarter to one half of all women who had been physically assaulted by their partners said that they had suffered physical injuries as a direct result. The abused women were also twice as likely as non-abused women to have poor health and physical and mental problems, even if the violence occurred years before.
Although pregnancy is often thought of as a time when women should be protected, in most study locations, between 4% and 12% of women who had been pregnant reported being beaten during pregnancy. More than 90% of these women had been abused by the father of the unborn child and between one quarter and one half of them had been kicked or punched in the abdomen.
For policy makers, the greatest challenge is that abuse remains hidden. At least 20% of women reporting physical violence in the study had never told anyone before being interviewed. Despite the health consequences, very few women reported seeking help from formal services like health and police, or from individuals in positions of authority, preferring instead to reach out to friends, neighbours and family members. Those who did seek formal support tended to be the most severely abused.
