    Durante a pandemia de COVID-19, a prevenção, o diagnóstico e o processo de tratamento foram bastante discutidos, acelerando-se investigação que permitiu produzir vacinas para proteção contra o vírus SARS-CoV-2 e redução de complicações fatais em tempo record. Muitos aspectos da vida humana foram afectados, de entre os quais adquire importância para a saúde das mulheres compreender o impacto da COVID-19 no seu ciclo menstrual. Devido à novidade do tema e ao facto de o conhecimento sobre esta questão ser escasso, há necessidade de estudos sobre esta possível interação. Este estudo teve como objetivos identificar os efeitos da vacina e da infeção por COVID-19 no ciclo menstrual de raparigas portuguesas a frequentar o ensino superior; verificar a associação entre factores individuais e alterações no ciclo menstrual após o contacto com o vírus SARS-CoV-2, por infeção ou por vacina. Tratou-se de um estudo transversal e observacional, utilizando um questionário para a recolha de dados. A amostra incluiu 296 adolescentes com idades compreendidas entre os 18 e os 24 anos (M=20,80±1,69), sendo 98,6% do sexo feminino, 0,7% intersexo e 0,7% preferiu não se dizer. Mais de metade da amostra teve COVID-19 apenas uma vez (51,1%) e tomou duas doses da vacina (54,7%). Os resultados apontam para alterações nos ciclo menstrualmais notórias na redução do período menstrual, dimunição do fluxo e aumento de coágulos. Mais de 10% relatam ter piorado as dores abdominais, as dores de cabeça e o cansaço físico generalizado. Outros fatores precisam de ser estudados a fim de clarificar estes efeitos

  • Interests and curiosities about sexuality of children and adolescents from northern Portugal
    Publication . Anastácio, Zélia; Alves, Regina; Antão, Celeste; Gil-Llario, María Dolores; Ballester-Arnal, Rafael
    Sexuality education is a part of the health education process in schools. However, many programs of sexuality education do not consider the needs of children and adolescents. This study is based on an analysis of the interests of children and adolescents about sexuality. The sample covered 32 classes from primary school to higher education in the northern region of Portugal. The methodology was mixed, collecting data through open questions. It used an A5 white page, containing only options to indicate age, school grade, and sex. In the white space, students wrote their questions/doubts. A database was built in the program SPSS and categories were established a priori following the key concepts for sexuality education defined by UNESCO. A pattern of issues and interests was found depending on the age group and sex, noting that the children’s interests are related to conception, birth, and the well-being of the fetus/newborn. Adolescents’ interests are focused on contraception, sexually transmitted infections, and relationships. This study can help teachers to promote sexuality education which is appropriate to the developmental stage of their students, motivating them to better learn and leading to a reduction in risky sexual behaviors and conscious decision making for healthy sexuality.

  • Relation between covid-19 infection and vaccine and menstrual cycle changes of portuguese adolescents in higher education
    Publication . Anastácio, Zélia; Fernandes, Sara Cerejeira; Alves, Regina; Antão, Celeste; Carvalho, Paula; Ferreira, Silvana Margarida Benevides; Condessa, Maria Isabel Cabrita
    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.
