Data on pubertal development in Greek boys. A longitudinal study

Abstract

ObJEctIVE: Longitudinal data on boys' puberty evolution are not available in Greece and very few such studies have been reported world-wide. We present data from a longitudinal study on height, weight, bMI and age at the different pubertal stages in Greek boys. DEsIGN: At the start of the study 204 prepubertal boys aged 8-10 years, were enrolled. Measurements were carried out every 3-6 months for 7.5 years. rEsULts: At pubertal stage G2 the mean age and sD was 10.3 (1.0), the height 143.4 cm or 82.3% of final height and the bMI 18.6 kg/m 2 . Mean age at peak height velocity was 13.2 (1.0) years and at final height 17.1 (0.9) years. At peak height velocity, the height accounted for 91.5% of the final height. the time elapsed from the beginning to the end of puberty (duration of pubertal process) was 6.2 (0.6) years. the height gain during puberty was 31.0 (4.0) cm and the weight gain 36.3 (8.1)kg. cONcLUsIONs: Longitudinal data on pubertal development are rather sparse, especially for males. Although the present study was carried out in an urban population of the Athens region, the data could be useful in delineating prognosis of puberty evolution and final height in boys.

Later puberty onset among chronically undernourished adolescents living in a Karachi slum, Pakistan

“…The current study assessed puberty onset as Tanner Stage G2, limiting comparable puberty assessment studies. A longitudinal study in Greece reported a mean AAG2 of 10.3 years which is similar to the AAG2 currently observed . The only contemporary Pakistan data on puberty onset in boys come from a cross‐sectional study in Lahore which reported a mean AAG2 at 11.3 ± 0.1 years .…”

Longitudinal investigation of training status and cardiopulmonary responses in pre- and early-pubertal children

“…Thus a limitation of the present study is the absence of a post-pubertal group. While the onset of puberty is reported to precede the age at PHV (Al Alwan et al 2010;Pantsiotou 2007), future research should seek to extend the present study design to incorporate measurements that span the maturational period.…”

“…The anthropometric characteristics of the children changed significantly over time, but there was no significant difference between groups (trained and untrained; Table 1). Participants were classified as pre-pubertal and pubertal according to previous studies cross-referencing age at PHV with invasive or intrusive measures of maturation (Al Alwan et al 2010;Pantsiotou 2007). .…”

Puberty Onset among Boys in Riyadh, Saudi Arabia

“…Defining the age of pubertal onset based on pubic hair development, Kanbur-Öksüz et al found Turkish boys entered puberty (P2) by a mean age of 11.53 years. 27 More appropriately defining the age of pubertal onset by G2, Pantsiotou et al 28 carried out a prospective study to evaluate pubertal development in Greek boys. They included 204 pre-pubertal boys between the age of 8 and 10 years who were followed over an average of 7.5 years in duration.…”
