====== Menstruation ======

Adult and young female [[start|Lifelines]] participants were asked about menstruation and menstrual pain ([[sections|section]]: [[reproduction & development]]).\\
A large subcohort of adult female participants answered more detailed questions on this topic in the context of an [[additional assessments|additional questionnaire]] on women's reproductive health ([[ROAQ]]).\\ 
Some of these questions were also asked in the context of our birth cohort, [[NEXT]].
