Background: Previous results on growth patterns of children from centralsouthern Italy (Abruzzo region) showed an increasing tendency to obesity and suggested that the secular trend was still in progress in this region. However, data on pubertal development was lacking. Objective: The objective of the study was to provide population data on pubertal development in a sample of 535 boys aged 6–14 years as a contribution to the ongoing debate on earlier onset of pubertal traits and on the slowing down of the secular trend. Methods: A cross-sectional survey was used. Data for genital and pubic hair development (GD and PHD) were analysed by probit analysis. Results: The boys start developing sexual characteristics at age 9: 13.3% had entered stage 2 of GD and 8.9% showed PHD. At 13 years of age, 5% and 7.4% were still in stage 1 of GD and PHD, respectively, whereas almost one-third had attained stage 5 for both sexual characteristics. The median age for attainment of stage 2 was 11.2 years for GD, 11.5 years for PHD and 11 years for one or both of them. Conclusions: These results are in line with those for several European and industrialized countries and do not show a significantly earlier onset of sexual maturation.

Abstract

Background: Previous results on growth patterns of children from centralsouthern Italy (Abruzzo region) showed an increasing tendency to obesity and suggested that the secular trend was still in progress in this region. However, data on pubertal development was lacking. Objective: The objective of the study was to provide population data on pubertal development in a sample of 535 boys aged 6–14 years as a contribution to the ongoing debate on earlier onset of pubertal traits and on the slowing down of the secular trend. Methods: A cross-sectional survey was used. Data for genital and pubic hair development (GD and PHD) were analysed by probit analysis. Results: The boys start developing sexual characteristics at age 9: 13.3% had entered stage 2 of GD and 8.9% showed PHD. At 13 years of age, 5% and 7.4% were still in stage 1 of GD and PHD, respectively, whereas almost one-third had attained stage 5 for both sexual characteristics. The median age for attainment of stage 2 was 11.2 years for GD, 11.5 years for PHD and 11 years for one or both of them. Conclusions: These results are in line with those for several European and industrialized countries and do not show a significantly earlier onset of sexual maturation.
