Abstract(s)
In a period globally known as long COVID, several post-acute infection sequelae
and vaccination effects have been discussed. Objectives: This study aimed to identify the
effects of COVID-19 infection and vaccines on the menstrual cycle of adolescents attending
higher education and to verify the association between personal health factors and changes
in their menstrual cycle after contact with the virus SARS-CoV-2 via infection or via the
vaccine. Methods: A cross-sectional study was conducted using a questionnaire for data
collection, applied online to Portuguese higher education adolescents aged between 18 and
24. The sample included 401 individuals. The statistical analysis of data was performed
using SPSS. Results: More than half of the sample had a COVID-19 infection only once
and took two doses of the vaccine. The mRNA Comirnaty 30 μg BioNTech vaccine was
administered to 73.1%. The most common menstrual changes were an increase in blood
clots, the blood becoming darker, shorter menstrual cycles, scarcer blood flow, and more
irregular cycles. Menstrual changes correlated significantly with vaccination but not with
infection. Conclusions: This study showed a lower percentage of women affected than
other studies carried out closer to the pandemic period, which could mean that the effects
are diminishing over time. Thus, adolescents’ menstrual health should be monitored.
