Objective:
To understand the perceptions of school adolescents about the menstrual cycle.
Method:
This was an exploratory mixed-methods study conducted at a State Technical School in the state of São Paulo. Descriptive statistical analysis was performed for the quantitative data, and Iramuteq software was used for the qualitative data. The findings were compared with the principles of Reproductive Justice.
Results:
Thirty-four adolescents participated in this study. It was found that 17% had difficulty purchasing sanitary pads, 88% felt insecure when menstruating, and 53% had missed school because they were menstruating. All stated that they had learned about menstruation at school. Five thematic categories emerged: 1) Challenges of Menstruation at School; 2) Education and Conversations about Menstruation in the Family Environment; 3) Support and Counseling; 4) Physical and Practical Difficulties of Menstruation; 5) Shame and Stigmatization.
Conclusion:
The research reveals that menstruation significantly impacts the lives of adolescents, causing insecurity and absenteeism. Schools play a significant role in disseminating information on the subject, and the data obtained point to the need to broaden the debate and reduce stigma.
