"Both society and the health-care sector need to be aware of the importance of exposure to violence and its impact, not only on social well-being, but also on women's long-term health," said Mario Flores, from the National Institute of Public Health in Mexico.
Worldwide, violence against women is a critical problem. It is established that experiencing violence can cause depression, substance abuse and other disorders in women, its possible effects on heart and blood vessel disease are a new area of study, researchers said.
This narrowing is an early sign of increased risk for stroke. A leading cause of death and disability, a stroke occurs when the blood vessels to the brain either become blocked by fatty substances or burst, preventing blood flow to the brain.
Study participants included 634 healthy women from Southern Mexico from the Mexican Teachers' Cohort, a national study of health and lifestyle among female teachers throughout Mexico. Their average age was 49 years, and almost one-fifth were natives.
All participants also underwent imaging tests with sound waves to measure the thickness of the blood vessels in the neck.
"Although our findings support the theory that exposure to certain types of violence may have an impact on women's health, further analysis and studies must be performed in order to generate solid data to be able to change clinical practice and guide public health interventions," Flores said.
