The influence of physical activity, body mass index and urinary levels of prostaglandin (PGF2α) with the incidence of primary dysmenorrhea in adolescents

Objective: This study aims to investigate the effect of physical activity, body mass index (BMI), and levels of prostaglandins (PGF2 alpha) urine on the occurrence of dysmenorrhea in adolescents. Methods: A total of 128 female students included in the study. The study was conducted from January to March 2023 using a cross-sectional design. This study utilized the Menstrual Symptom Questionnaire (MSQ) and gynecological examination with ultrasonography. The urinary prostaglandin (PGF2 alpha) was measured using the enzyme linked immuno sorbent assay (ELISA). Data were analyzed using the chi-square test and logistic regression test. Results: The age range of the participants included in the study was 14-17, with a mean age of 15.85 +/- 0.65. There was an correlation between physical activity, BMI, and urinary prostaglandin (PGF2 alpha) levels with the incidence of dysmenorrhea in adolescents (p < 0.001). In multivariate analysis, it revealed that underweight, and had a high urinary prostaglandin significant correlated to primary dysmenorrhea with odds ratio 4.78 (95% confidence interval [CI] 1.98-11.54) and 4.88 (95% CI 1.98-12.08), respectively. High physical activity and overweight was not associated with incidence of dysmenorrhea in adolescents. Conclusion: This study provides valuable insights into the correlation between physical activity, BMI, and levels of prostaglandins (PGF2 alpha) in urine. A high level of urinary prostaglandin was found to be the most influential factor in the incidence of primary dysmenorrhea in adolescents. By addressing factors associated with dysmenorrhea in adolescents, healthcare professionals can potentially enhance well-being by reducing menstrual pain and encouraging a healthy lifestyle to prevent dysmenorrhea.
