One-third of women around the world have experienced physical or sexual violence at the hands of their intimate partners with consequences from post-traumatic stress disorder, anxiety, and depression, to sexually transmitted diseases, including HIV. In a new study in 29 low-income and middle-income countries, researchers at Columbia University’s Mailman School of Public Health have identified yet another serious health risk associated with intimate partner violence (IPV): smoking. The findings were published online in Global Public Health.
