Resumo: | Objective: To characterize the menstrual cycle (regularity and menstrual flow length), the prevalence of dysmenorrhea and selfmonitoring of the cycle in students from Lisbon region, and explore the effect of chronological age, age at menarche and body mass index (BMI) on menstrual disorders. Methods: This is a cross-sectional study with 848 girls aged 12–18 years. A questionnaire about the sociodemographic context and characteristics of the menstrual cycle, and weight and height measures were assessed. BMI was classified according to International Obesity Taskforce criteria. A descriptive analysis of the variables was made, and Odds Ratios (ORs) and 95% confidence intervals (95%CIs) were determined. Results: Mean age at menarche was 12.4 years and mean BMI was 22.0kg/m2. Among adolescents, 59% have regular menstrual cycle, 83% have menstrual flow length of ≤6 days. 88% suffered from dysmenorrhea, among which 8,7% declare absenteeism from school and 49% took pain medication, and 65% self-monitor their menstrual cycle. Higher maternal education was associated with a higher self-monitoring of menstrual cycle among the sample (OR 1.60; 95%CI 1.15–2.17). Girls with menarche <12 years-of-age are more likely to have menstrual flow length of >6 days (OR 1.73; 95%CI 1.19–2.51) and dysmenorrhea (OR 1.87; 95%CI 1.11–3.16) than those with menarche ≥12 years-of-age. No significant association between BMI and menstrual cycle variables was observed. Conclusions: The results suggest that menstrual disorders are frequent and may be associated with early menarche, but not with BMI. It is important to encourage self-monitoring of the menstrual cycle to detect menstrual disorders timely and promote health and well-being. |

Métodos: Este é um estudo transversal com 848 meninas entre 12 e 18 anos. Foi aplicado um questionário sobre contexto sociodemográfico e características menstruais e feita a medição do peso e altura. O IMC foi classificado pelos critérios da International Obesity Taskforce. Fez-se uma análise descritiva das variáveis e determinaram-se Odds Ratio (p<0,005; IC95%). Resultados: A média da idade de menarca foi 12.4 anos e do IMC foi de 22.0kg/m2. Entre as jovens, 59% afirmaram ter ciclo menstrual regular, 83% menstruação com duração ≤6 dias, 88% sofrem de dismenorreia, entre as quais 8,7% faltaram à escola e 49% consumiram analgésicos, e 65% automonitoram o ciclo menstrual. Uma educação materna elevada está associada a maior monitorização do ciclo menstrual entre as jovens (OR 1,60; IC95% 1,15–2,17). Meninas com idade de menarca <12 anos têm maior chance de ter menstruação com duração >6 dias (OR 1,73; IC95% 1,19–2,51) e dismenorreia (OR 1,87; IC95% 1,11–3,16) do que aquelas com menarca ≥12 anos. Não se observou associação entre o IMC e as características menstruais. Conclusões: Os resultados sugerem que os distúrbios menstruais são frequentes nas adolescentes e podem estar associados com a menarca precoce, mas não com o IMC. É importante incentivar a automonitoramento do ciclo menstrual para detectar adequadamente as perturbações menstruais e promover a saúde e bem-estar.Sao Paulo Pediatric Society2022info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://hdl.handle.net/10316/103477http://hdl.handle.net/10316/103477https://doi.org/10.1590/1984-0462/2022/40/2020494eng1984-04620103-0582Marques, PatriciaMadeira, TiagoGama, Augustainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-11-15T21:35:58Zoai:estudogeral.uc.pt:10316/103477Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:20:18.392467Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
