Abstract
Objectives: This study aims to evaluate the prevalence of premenstrual syndrome (PMS) among Polish adolescents and explore its associations with mental health outcomes, lifestyle factors, and risk behaviours. Additionally, it seeks to examine the impact of PMS on quality of life, contributing to the foundation for initiatives that enhance adolescent menstrual health. Methods: This research is part of the POLKA 18 study, a youth-led cross-sectional survey conducted between April and December 2019. Final-year high school students were surveyed using paper-based, self-reported questionnaires. Statistical analysis was performed using the R programming language in RStudio, with a significance threshold of p-value < 0.05. Results: A total of 1545 valid responses were analysed. PMS was reported by 33.9% of respondents, with over 80% experiencing premenstrual symptoms. Adolescents with negative mental health outcomes, such as self-harm or suicidal ideation, were significantly more likely to report PMS (p ≤ 0.001). PMS was also strongly associated with anxiety and panic attacks (p < 0.001). Risk behaviours, including smoking (p = 0.006), illicit substance use (p < 0.01), and increased alcohol consumption in the past 30 days (p < 0.001), were more prevalent among adolescents with PMS. Furthermore, respondents with PMS reported poorer school performance (p = 0.002), higher stress levels (p < 0.001), and a more negative perception of their overall health (p < 0.001) compared to peers without PMS. Conclusions: PMS is significantly associated with mental health issues, engagement in risky behaviours, higher stress, and diminished self-perceived health and academic performance. These findings highlight the need for further research and the development of targeted interventions to improve adolescent menstrual health.
