“…It must be added that the mixed population of Istanbul city is quite representative of the whole of Turkey [7,10,39]. Thus, the results of our study are in agreement with those from most of the studies from the Western world reporting no secular trend for boys [3,11,30,32]. Indeed, reported ages for onset of puberty in boys in different studies throughout the decades do not show a consistent pattern for a secular trend through these years among different populations.…”

“…While there is ample evidence that the onset of puberty is occurring at increasingly younger ages [31], this finding is primarily based on studies of menarcheal age or breast development of girls [18,31], and data on sexual maturation of boys analyzed together with the growth pattern throughout puberty are scarce [1,13,21,24] and open to discussion with respect to secular trends [3,11,23,30,32,41]. Some studies have reported that there is no notable earlier maturation of boys [3,11,30,32], while a positive secular change has been reported for Swedish [23] and Hong Kong boys [41].…”

Analysis of puberty and pubertal growth in healthy boys

et al. 2006

The aim of this study was to provide normative data for the onset and tempo of puberty in healthy boys. The analyses are based on data that were collected and evaluated biannually on 1112 Turkish school children aged from 8 to 18 years and a subsample of 30 boys who had reached final height (FH). The data were analyzed cross-sectionally in the total group and longitudinally in the subsample. Mean age and height (Ht) at onset of puberty were 11.6 +/- 1.2 years and 146.1 +/- 7.7 cm, respectively. Peak height velocity (HtV) was 10.1 +/- 1.6 cm. Total pubertal height gain was 26.4 +/- 4.3 cm. The duration of puberty was 4.9 +/- 0.6 years. Height at onset of puberty was positively correlated with FH (p < 0.0001) and with duration of puberty (p = 0.03). Body mass index at onset of puberty correlated negatively with age at onset of puberty (p < 0.009) and with the duration of puberty (p = 0.05) but not with FH. In conclusion, these results provide normative data for Ht and HtV for each testicular volume stage for boys in puberty. Height at onset of puberty is the most important determinant of FH. There is no secular trend for the onset of puberty. Weight does seem to affect the onset and tempo of puberty but not FH.

“…The mean age for PH2 in boys in the present study was 12.02 years, while it was 13.4 years in England, 12.7 years in Sweden, 12.2 years in Switzerland, 11.5 years in Greece, 12.4 years in Spain, and 11.8 years in Denmark 13 ' 19 ' 21 ' 32 · 35,36 . The median ages for attainment of PH2 were reported as approximately 11.2 years for non-Hispanic Black boys, 12 years for non-Hispanic White boys, and 12.3 years for Mexican-American boys 1 .…”

Aim: To investigate the pubertal development of Turkish school children, to look for possible secular trends in pubertal development. Methods: 1,562 girls and 1,749 boys (aged 6-16.5 years) from urban and rural schools were studied. Weight and height were measured and body mass index was calculated. Pubertal stages were assessed according to Tanner. Testicular volume was determined using an orchidometer. Menarcheal age was recorded. Results: In girls, mean ages at breast stage (B) were 7.74 ± 1.08 years for Bl, 10.16 ± 0.97 for B2, 11.72 ± 1.29 for B3, 12.97 ± 1.17 for B4, and 13.66 ± 0.89 for B5. Mean ages at pubic hair stage (PH) were 8.72 ± 1.50 years for PHI, 10.57 ± 1.39 for PH2, 12.12 ± 1.10 for PH3, 13.10 ± I.04 for PH4, and 13.87 ± 0.83 for PH5. Mean age at menarche was 12.41 years. Menarcheal age was earlier in overweight and obese children compared with that in normal children. In boys, mean ages at each maturity stage according to testis volume (G) were 8.70 ± 1.38 years for Gl, II.76 ± 1.28 for G2, 12.81 ± 1.0 for G3, 13.17 ± 0.87 for G4, and 13.87 ± 0.98 for G5. Mean ages at PH in boys were 9.39 ± 1.81 years for PHI, 12.02 ± 1.33 for PH2, 13.05 ± 0.88 for PH3, 13.42 ± 0.87 for PH4, and 14.02 ± 0.92 for PH5. Conclusions:The current study provides an upto-date reference of normal sexual maturation of Turkish children. While the mean age at onset of puberty in boys was comparable to that of other populations in the world, girls were found

“…9 It has recently been reported that in the 1990s the mean age at pubertal stage G2 of mainly middle class Athenian boys was 11.0 years. 10 All the aforementioned studies were cross-sectional and the ages could be at least 0.5 year earlier. The lower age at onset to puberty observed in the present study may be due to its longitudinal nature and possibly to the higher socioeconomic class of the boys, or both, 11,12 rather than to a secular trend.…”

Data on pubertal development in Greek boys. A longitudinal study

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.

Sexual maturation of Greek boys

Abstract: The age at which genital development occurs in Greek boys is no different from that of other Caucasian populations. However, pubic hair in Greek boys develops significantly earlier.
