Menarcheal age in University of Warwick young women.

Data from the final 16 years of a 28-year ongoing survey of menarcheal age are reported. From 1971 onwards, recalled aged at menarche was recorded for all young women entering the University of Warwick. These data show that mean menarcheal age is increasing, a trend which is independent of father's occupation, family size, position of girl in the family, and physique. This continues a similar upward tendency noted in a preceding study in Swansea. It appears that the downward trend to earlier age at menarche of the earlier decades of this century has been replaced by one in the opposite direction.

Social class and diachronic trends in physique in young university women.

In a large sample of female students admitted to the University of Warwick in the period 1971-86, physique as measured by height, weight and ponderal index was examined in relation to family variables and socioeconomic class. Stature and weight both show a secular tendency to increase, and there is no indication of any slowing of rate. The different social classes do not participate equally in these trends, in a way that is difficult to reconcile with the attribution of the diachronic changes to simple improvement in environmental conditions. Maternal competence is suggested as a possible factor in the pattern of class difference.

A 12-year study of menarcheal age.

Data on menarcheal age were collected on girls admitted to the University College of Swansea over a 12-year period. It appears that the downward trend in menarcheal age ceased in girls born about 1946 (the 1965 student intake) and that an upward swing may have since occurred. This change in the secular trend is not due to the association of menarcheal age with family size or of position in sibship, or to changes in the regional composition of the student intake. The well established effect of physique remains, but there is no effect of socio-economic status as assessed by the Registrar-General's classification of the father's occupation.

End of the trend? A 12-year study of age at menarche.

A 12-year study of menarchial age in all girls entering the University College of Swansea (1959-70) suggests that the downward trend in age at menarche has ceased in Britain. The turning point appears to have occurred in girls born about 1946.
