One out of every five children don't live past the age of five in Afghanistan, and war isn't the only reason that the country has one of the world's highest child mortality rates. A new study has linked the problem to Afghan mothers' lack of autonomy and education: Afghan and Japanese researchers found that 79 percent of Afghan mothers need permission from the head of their household to bring a child to the doctor, and they may need a male relative to accompany them to the clinic. Seventy-one percent of the mothers surveyed have not attended at least a year of school, and 18 percent had their first child before they turned 16. In addition to a better health care system and the elimination of poverty, the study calls for formal education for women and changes in the behavior of Afghan men toward women. [Reuters]
