When we analyzed the specific puberty milestones individually, we attempted to capture potential programming effects of specific features of pubertal development, such as the association between prenatal PFOS exposure and Tanner stages of breast development, but not the remaining markers.
Most studies that have investigated bone mineral parameters at different skeletal regions using DXA in RG (Maimoun et al., 2013a; 2013b; Vicente-Rodriguez et al., 2007; Vosoberg et al., 2016) and AG (Dowthwaite et al., 2006; 2011; Erlandson et al., 2012a; Greene et al., 2012; Lehtonen-Veromaa et al., 2000a; Maimoun et al., 2011; 2013a; Pikkarinen et al., 2009; Vicente-Rodriguez et al., 2007) have been performed in peri-pubertal girls with different maturation levels, where studied groups have been composed of gymnasts ranging from Tanner stages I-V.
Differences in the clinical measurements among the different Tanner stages were evaluated using Kruskal-Wallis one-way analysis of variance (ANOVA) on ranks coupled with Dunn's method as a multiple comparison procedure.
As per Table No.4, we found very strong correlation and statistically highly significant p-value (p < 0.001) between Reference age for Tanner stages of pubic hair taken from the UNICEF Manual for Medical Officer (2005), [7] Physical-Dental age, Radiological age and Final age, which shows that Tanner staging of pubic hairs is a good parameter for estimation of age between 10 to 16 years for both males and females.
Children with IR were primarily girls (P = 0.035); in addition, significantly more preterm birth and higher Tanner stages were observed in the IR group (Tables 1 and 2).
Although our study showed that E2 levels were not significantly different in normal-weight children and obese children in all Tanner stages, lower LH response to GnRH stimulation tests may partly reflect a negative feedback effect by estrogen.
