Global burden and trends in female premenstrual syndrome study during 1990-2019.

Purpose: Premenstrual syndrome (PMS) is prevalent worldwide and considered a crucial issue regarding women's health. In the present study, the Global Burden of Disease (GBD) Study 2019 dataset was utilized to assess the distributional trends in PMS burden and prevalence in regional, national, and sociodemographic index (SDI) categories.

Methods: The analytical methods and approaches used in the 2019 GBD study were adopted to investigate the incidence rates and disability-adjusted life years (DALY) related to PMS in 204 countries or regions. Age-standardized incidence rates (ASIR), 95% uncertainty intervals (95% UI), and annual percentage changes (EAPC) were calculated from the data.

Results: The global incidence and disability-adjusted life years of PMS exhibited a declining trend in the year 2019. Regions with medium-low SDI had the greatest burden of PMS, with the regions of South Asia (ASR = 7337.9 per 10,000) exhibiting the greatest Age-standardized incidence rates, while the high-income North American states presented the fastest upward trends in Age-standardized disability-adjusted life year rates. At the national level, 107 nations exhibited a decreasing trend in PMS incidence ASR, while 97 nations exhibited an increasing trend, with the United States presenting the greatest increase.

Conclusions: The present study highlighted that even though the global PMS incidence and disability-adjusted life years have decreased from the year 1990 to 2019, PMS remains a prevalent health concern for women worldwide. While addressing preventive measures and treatment, it is also important to consider the regional and national differences in PMS to develop further effective and targeted health policies.
