title: [Puberty in Icelandic girls.].
abstract: In a crosssectional study, 2775 healthy Icelandic girls, aged 6-16 years, were examined for physical signs of puberty. The study was performed in 1983-1987 and was a part of a larger crosssectional study of growth and development of 5526 Icelandic children all of whom were examined by the authors. Breast development stage 2 according to Tanner (B 2) was considered the first sign of puberty in girls. The mean age of Icelandic girls reaching B 2 was 10.84 years (SD 1.43). The mean time interval between B 2 and menarche was 2.42 years. The first signs of pubic hair growth, Tanner stage 2 (PH 2) were found at 11.46 years (SD 1.25). The mean time interval between PH 2 and PH 5 was 3.40 years. Comparison with studies from other countries is difficult because of different methods and different study designs, but the timing and tempo of puberty in Icelandic girls seems to be similar to what has been reported from other Nordic countries and countries in Western-Europe.
