“…Few studies have reported the agreement between youth-assessed puberty using the PDS and clinicianassessed puberty [13,14,27,28]. Furthermore, comparing the current study to those in the literature is problematic owing to the use of different agreement statistics and to the use of five-point over three-point puberty development scales.…”

“…Two recent studies reported agreement between youth-assessed puberty using the PDS and clinicianassessed puberty use a three-point scale for puberty similar to the current study. One study conducted in the USA reported a moderate strength of agreement (κ = 0.57; 95% CI: 0.49-0.66), but this kappa coefficient was unweighted and not stratified by sex thereby limiting the sex-wise comparison to the current study [27]. Conversely, a Brazilian study reported high levels of agreement but used intraclass correlation coefficients of 0.82 for boys (95% CI: 0.70-0.90) and of 0.81 for girls (95% CI: 0.70-0.89) [13].…”

ObjectivesStaging sexual maturation is an integral component of adolescent research. The Pubertal Development Scale (PDS) is commonly used as a puberty self-assessment tool because it avoids the use of images. Among the youth living in rural Pakistan, we determined the accuracy of self-reported pubertal assessments using a modified PDS compared to the ‘gold standard’ of physically assessed Tanner stages by a physician.MethodsThe strength of agreement between self-assessed puberty using a modified PDS and the ‘gold’ standard of physician-assessed Tanner stages was reported using weighted kappa (κw) for girls (n = 723) of 9.0–14.9 years of age or boys (n = 662) of 10.0–15.9 years of age living in the rural District of Matiari.ResultsAgreement between the gold standard and self-assessment for puberty was substantial, with a κw of 0.73 (95% confidence interval [CI]: 0.67; 0.79) for girls and a κw of 0.61 (95% CI: 0.55; 0.66) for boys. Substantial agreement was observed for both boys and girls classified as thinness but only for girls with a normal body mass index. Those who were classified as severely thin had moderate agreement. The prevalence of overestimation was 18.5% (95% CI: 15.9–21.5) for girls and 2.7% (95% CI: 1.7–4.3) for boys, while the prevalence of underestimation estimation was 8.0% (95% CI: 6.2–10.2) for girls and 29.0% (95% CI: 25.8–32.6) for boys.ConclusionsMost girls and boys assessed their pubertal development with substantial agreement with physician assessment. Girls were better able to assess their puberty, but they were more likely to overestimate. Agreement for boys was also substantial, but they were more likely to underestimate their pubertal development. In this rural Pakistan population, the PDS seems to be a promising tool for self-assessed puberty.

“…The Puberty development scale (PDS) was used to evaluate the puberty development at each investigation. Puberty category scores (PCS) were calculated according to the total scores of three items including menarche (score 0 or 1, namely “without or with”), breast development (score 1 to 5), and body hair growth (score 1 to 4) ( 23 ).…”

BackgroundThyroid volume (Tvol) is associated with many factors, but the current reference values for Tvol in children with sufficient iodine intake are inappropriate and need to be updated. Moderate changes in thyroid morphology and accentuated increases in body fat percentage occur during puberty as an adaption of the body and sexual development occurs. This study aimed to evaluate the influences of physical growth on Tvol and propose an easily applicable method for conducting Tvol assessments in pubertal girls with sufficient iodine intake.MethodsA cohort study was conducted on 481 pubertal girls in East China from 2017 to 2019. B-ultrasound was used to assess Tvol. Multiple linear regression models were used to estimate the associations of Tvol enlargement (dTvol) with changes in height (dH), weight (dW), waist circumference (dW), body mass index (dBMI), and body surface area (dBSA). Thyroid volume indexes (TVIs), including height thyroid volume index (HVI), weight and height thyroid volume index (WHVI), body mass index thyroid index (BMIV), and body surface area thyroid index (BSAV), were calculated to explore an appropriate method for Tvol assessments by Spearman correlation analyses.ResultsTvol, height, weight, BMI, and BSA increased significantly from baseline to follow-up (P<0.001). The associations between dTvol and physical growth were only observed in the 13 to 14-year-old group. dH, dW,dBMI, and dBSA were positively related to dTvol, with the maximum β of 5.74 (95%CI: 2.54 to 8.94) on dBSA, while dWC was negatively related to dTvol (β= -0.05, 95%CI: -0.08 to -0.03). Both dHVI and dBSAV were not associated with dH, dW, dBMI, or dBSA in both age groups (P>0.05).ConclusionsThyroid volume was associated with physical growth in pubertal girls in East China, both age and anthropometric measurements must be comprehensively considered to establish the reference values for Tvol. HVI, and BSAV may be better indicators for Tvol assessments in pubertal girls.

“…The PBS has adequate validity and reliability. The internal consistency ranges between 0.91 and 0.96 and the test–retest reliability was 0.81–0.92 (Koopman‐Verhoeff et al., 2020). The PBS was used for classifying each subject from MA and CA in two groups: pre‐, early‐, and midpuberty (for boys—PBS = 3–8; for girls—PBS = 2–3 and no menarche) versus late‐ and postpuberty (for boys—PBS: 9–12; for girls—PBS = 7–8 and menarche).…”
