For mood and premenstrual tracking


Epidemiological data shows that 75% of women of reproductive age suffer from some premenstrual syndrome (PMS) symptoms, while 3% to 8% reported extremely severe PMS symptoms. A study on PMS prevalence among different countries worldwide found that 47.8% (95% CI: 32.6–62.9) of women have PMS. Symptoms include tender breasts, bloating, irritability and aggression, anxiety, tiredness, and food cravings.

Currently, there is no test for PMS and to be diagnosed, a woman must have physical symptoms and mood changes. These must occur before her menstrual period and disappear after the onset of the period.

Some researchers at McMaster University have developed a new app that can be used to track mood and premenstrual symptoms prospectively, daily. Users will be able to see if their symptoms are severe enough so that they will be able to use this information to bring to their health care providers to help with the management of mood and premenstrual symptoms.
