The development of anxiety in women could be related to biological as well as adverse life experiences. Hormonal fluctuations that women experience during puberty, the menstrual cycle, and menopause could be contributing factors. However, not all women will develop anxiety disorders in response to these fluctuations. It is important to consider other biological contributors and environmental experiences. Women may be more likely than men to experience stressors contributing to anxiety disorders. For example, childhood sexual abuse occurs twice as often to girls as to boys and, in adulthood, women may experience sexual assault at 10 times the rate of men.
