dc.description.abstractThe purpose of this study is to analyse the influences of the degree of urba ni zation in the occurrence of the first menstruation, and to present the secul ar trend of this important indica tor of sexual maturation in Portugal, be tween 1880/90 and 1980. Menarcheal age was studied in 8261 school girls from th e nor th and centre of Portugal. The sample was collected, between 1981 and 1983, by status quo metho d and the median age at menarche, estimated by probits, wa s 13.18 (S.D.±1.20 years). Urban girls had always earlier median age at menarch e than rural ones. A secular trend towards earlier menarche was observed - age at menarche declined from 15 (girls born in 1880/1890) to 12.42 years (girls born between 1970 and 1980).This trend must be rela ted to the general improvem ent in the population's standard living conditions, as the striking drop of postneonatal mortality rate shows after the 1960s and 1970s.eng
dc.description.abstractNeste trabalho pretendemos analisar a influencia do grau de urbanizacao no aparecimento do primeiro fluxo menstrual e apresentar a evolucao da idade d a menarca, em Portugal, no perfodo de 1880/90 a 1980. Uma amostra de 8261 escolares do norte e centro de Portugal foi recolhida, entre 1980 e 1983, pelo metodo status quo. A idade de menarca estimada por analise probftica foi de 13.18 anos. As raparigas que viviam em meio urbano apresentaram sempre medi anas inferiores as das zonas rurais. A evolucao secular mostrou-nos qu e a idade da menarca diminuiu de 15 anos ( raparigas nascidas em 1880/90) para 12.42 anos (escolares nascidas entre 1970 e 1980). Esta evolucao foi, provavelmente, resultante de uma melhoria da s condicoes de vida em Portugal, como e sugerido pel a acentuada diminuicao da mortalidade inf antil ap es 1960 e 1970.por
