Some mental and physical health concerns women face may be related to gender. A study from the Centers for Disease Control and Prevention (CDC) found that not only are women more likely to experience mental health concerns such as depression or anxiety, women also experience mental distress at higher rates than men do in all age brackets. Researchers continue to explore the various biological, environmental, and psychosocial factors potentially contributing to these differences. Dr. Richard Nakamura, a key contributor at the 2005 Surgeon General’s Workshop on Women’s Mental Health, states a focus on women’s health is vital, as “important biological differences related to hormones and brain structure may affect mental health risks, rates of disorders, and the course of those disorders.”
