The objective of this paper is to present the growth patterns of school children in Osijek--the city which was exposed to severe attacks during the aggression on Croatia. The mean height and weight of Osijek schoolchildren aged 7 to 18 and the menarcheal age in girls in academic year 1995/96 were compared to the analogous data collected in 1980/81. The secular changes in height were heterogeneo...

Early onset of menarche has been shown to be associated with breast cancer and ischaemic heart disease. Studies on age at menarche of the Malaysian population are poorly documented. This study aimed to determine the influence of anthropometric and socio-demographic factors on the age at menarche of university students in Malaysia. Data were obtained in 2010-11 from 961 students between the ages...

This study of secular trend in Portugal has shown that a positive increment in height occurred in Portuguese 18year-old males between 1904 and 2000, and a secular trend in the age at menarche, towards an earliest age, also took place. Mean height increased 8.93 cm, from 1904 to 2000, when reached 172,13 cm. Besides that, in 2000, statistically significant differences (p ≤ 0.001) among the distr...

Since the 19th century there have been clearly documented secular trends to increasing adult height in most European countries, with current rates of 10-30 mm/decade. Over the same period menarcheal age has also fallen steeply, but has now stabilized at approximately 13 years and may be rising again. Height trends tend to be greater in childhood than in adulthood due to the associated advance i...

BACKGROUND The ratio between the lengths of the second and fourth fingers (digit ratio: 2D : 4D), a purported negative correlate of prenatal androgen exposure, has been inversely related to age at menarche. However, a recent study found high digit ratios in carriers of a single variant in the LIN28B gene, which has been linked to delayed menarche. METHODS We investigated the association of di...
