Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Previous research on menstrual complaints in adolescents has considered sample sizes of approximately 1,000 participants to be representative of the population. Since this prospective cohort study about adolescent's menstrual complaints involved repeated measurements, and the literature suggested that repeated measurements of outcome variables increase study power and reduce the required sample size, this study aimed to include a total of 900 adolescents and 900 adults.
The study results were reported using descriptive statistical analyses. To compare dichotomous outcomes the chi-square test or the Fishers' exact test was used. Depending on the data distribution, the Student's t-test or Mann-Whitney U test was used to compare continuous outcomes. Mixed effects logistic regression was used for the association between menstrual complaints and the impact on daily life activities. The statistical analysis was performed in IBM SPSS Statistics version 28 using a two-sided p-values. P-values under 0.05 were considered statistically significant.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Adolescents
postmenarchal adolescents between 12 and 18 years old, (according to the WHO's definition of adolescents) with monthly menstruation
Menstruatie Educatie Kalender (Menstrution Education Calendar) application (MEK-app)
The MEK-APP is a mHealth application to evaluate menstrual complaints like heavy menstrual blood loss and dysmenorrhea. The MEK-APP is a calendar and facilitates daily monitoring of pain intensity using a Visual Analogue Scale (VAS), the amount of blood loss through a pictorial blood loss assessment chart (PBAC), and the impact of these complaints on daily life. The MEK-APP followed the waterfall methodology for software development and the usability was evaluated by both adults and adolescents(4). Furthermore, the MEK app has been approved by the privacy and security officers of Amsterdam UMC
Questionnaires
After registration for this study via www.mijnmenstruatie.nl (which has also been approved by the privacy and security officers of Amsterdam UMC), participants received the first digital questionnaire. This questionnaire consisted of a baseline questionnaire, the electronic self bleeding assessment tool (e-self-BATH) and the Menstrual Health Literacy questionnaire.
After using the MEK-app for at least one month, participants received an e-mail with the second questionnaire. This questionnaire consisted of the Menstrual Bleeding Questionnaire; Period ImPact and Pain Assesment; Pelvic Pain Impact Questionnaire; ENDOPAIN-4D; Endometriosis Health Profile 5 and iMTA Productivity Cost Questionnaire.
Adults
Postmenarchal adults between 19 and 60 years with monthly menstruation
