The mean and median age at menarche in 360 Khasi girls was found to be 13.22 ± 0.88 and 12.13 ± 0.79 years, respectively; socio-economic status was observed to be a strong predictor of age at menarche in this population.

BACKGROUND In recent studies a larger birth size has been shown to delay the timing of menarche. The mechanisms underlying this association are not clear, however, as birthweight is a predictor of body size in childhood, and a large body size is known to be associated with an early onset of menarche.

Data from a Finnish birth cohort followed to adulthood were analysed to determine whether there is any association between maternal age at menarche and the occurrence of atopy among oVspring. Methods—The study was conducted in 5188...

Tissue iron stores are commonly assessed by measuring serum ferritin. Adolescent girls are more prone to develop iron deficiency due to menstrual blood loss. Menstruation is an inflammatory process and we hypothesized that serum ferritin levels may be elevated during menstruation as it is an acute phase protein and hence serum ferritin measurement alone may not be truly reflective of iron statu...

This racially and ethnically diverse cohort (38% white, 40% Afr...

The hypothesis that the vacation-study-expectancy scholar regime produces most of the monthly rhythm of the age at menarche (AaM) was tested. Studies on monthly menarche incidence (MI) refuted climatic factors as a main factor in this rhythm, and indicated that the main factor of this rhythm is the succession of expectancies of study (Stu-months) or vacation (Vac-months) months within a year. T...
