According to a new study published in the Archives of Women′s Mental Health, more than 64% of women now experience premenstrual mood swings and anxiety, representing a "key public health issue globally." Most women in all age groups experience mood-related premenstrual symptoms every menstrual cycle. Dr. Jennifer L. Payne, director of the Reproductive Psychiatry Research Programme at the University of Virginia School of Medicine, stated that a majority of women reported that their premenstrual symptoms interfered with their everyday life some of the time.

In the study, more than 238,000 survey responses from women ages 18–55 from 140 countries on the Flo app were analyzed. The study results revealed that 85.28% of the women had food cravings, followed by mood swings or anxiety (64.18%) and fatigue (57.3%). The findings of the study also showed that 28.61% of women complained of premenstrual symptoms interfering with their everyday life during every menstrual cycle. On the other hand, 34.84% of women reported that their premenstrual symptoms interfered with their everyday life sometimes.

Dr. Payne stated that the incidence of reported premenstrual mood and anxiety symptoms varied significantly by country, indicating the differences in biology or culture as the factors leading to varied country-level rates. She further added that several treatment strategies are available to treat premenstrual symptoms that interfere with a womans everyday functioning, but only awareness of these symptoms will help women improve their quality of life.
