“…One previous study with girls in predominantly late pubertal stages 17 reported similar agreement rates with other studies examining children in early stages of puberty, 15,19 suggesting that pubertal stage may not influence agreement between self-assessment and clinical examination.…”

“…15,28 Some studies have reported similar or slightly higher agreement for pubic hair in boys, ranging from 58.0% to 78.0%. 15,19,28 A few studies found high agreement rates for breast stage (86.0%) and pubic hair for girls and boys (80.0% to 93.0%). 13,16 To our knowledge this study is the largest published to date, and evaluations by the child or parent and the examiner were blinded to pubertal assessment of the other party.…”

“…That may have introduced a systemic bias toward better agreement between ratings.

“…Only half of the boys in our study were able to assess their genital stage, which has also been shown previously. 15,28 One study using schematic drawings of Tanner stages similar to ours showed that 27% (n = 1150) of the boys reported a lower genital stage than they reported 1-1.5 years earlier when asked to repeat their selfassessments. 9 This finding indicates that self-assessment is unreliable.…”

“…[9][10][11][12] Previous investigations of the reliability of self-assessment have shown conflicting results. Some studies found reasonable agreement between self-assessment and examination by a physician, [13][14][15][16] whereas others found discrepancies. [17][18][19][20] Most studies include few children (girls, n = 37-182; boys, n = 23-172) in view of the broad age range of puberty.…”

BACKGROUND AND OBJECTIVES: Studies of adolescents often use self-assessment of pubertal maturation, the reliability of which has shown conflicting results. We aimed to examine the reliability of child and parent assessments of healthy boys and girls.METHODS: A total of 898 children (418 girls, 480 boys, age 7.4-14.9 years) and 1173 parents (550 daughters, 623 sons, age 5.6-14.7 years) assessed onset of puberty or development of breasts, genitals, and pubic hair according to Tanner stages by use of a questionnaire and drawings. Physicians' assessments were blinded and set as the gold standard. Percentage agreement, k, and Kendall's correlation were used to analyze the agreement rates.RESULTS: Breast stage was assessed correctly by 44.9% of the girls (k = 0.28, r = 0.74, P , .001) and genital stage by 54.7% of the boys (k = 0.33, r = 0.61, P , .001). For pubic hair stage 66.8% of girls (k = 0.55, r = 0.80, P , .001) and 66.1% of boys (k = 0.46, r = 0.70, P , .001) made correct assessments. Of the parents, 86.2% correctly assessed onset of puberty in girls (k = 0.70, r = 0.71, P , .001) and 68.4% in boys (k = 0.30, r = 0.37, P , .001). Children who underestimated were younger and children who overestimated older than their peers who made correct assessments. Girls and their parents tended to underestimate, whereas boys overestimated their pubertal stage.CONCLUSIONS: Pubertal assessment by the child or the parents is not a reliable measure of exact pubertal staging and should be augmented by a physical examination. However, for large epidemiologic studies self-assessment can be sufficiently accurate for a simple distinction between prepuberty and puberty.WHAT'S KNOWN ON THIS SUBJECT: Many population-based studies including pubertal children are based on self-assessment of pubertal maturation, the reliability of which is uncertain.WHAT THIS STUDY ADDS: Self-assessment is not reliable for precise pubertal staging. Simple distinctions between prepuberty and puberty showed moderate agreement with clinical examinations. Parents and girls tended to underestimate and boys to overestimate pubertal development by up to 50% and 30%, respectively.

Objective: The purpose of this study was to examine the longitudinal associations between cardiorespiratory fitness and health-related quality of life (HRQoL) in a sample of adolescents, and to determine whether changes in cardiorespiratory fitness were associated with HRQoL over a 2-year follow-up. Methods: This is a longitudinal analysis with 571 Portuguese adolescents (274 boys and 297 girls) aged 12-18 years. HRQoL was measured with the Kidscreen-10 questionnaire; the 20 m shuttle-run was used to estimate cardiorespiratory fitness; socioeconomic status was assessed with the Family Affluence Scale; and pubertal stage was assessed with Tanner stages. Linear regression and analysis of covariance (ANCOVAs) were used to examine the associations between cardiorespiratory fitness and HRQoL. Results: HRQoL decreased over a 2-year period both in boys and girls (P < .05).Moreover, girls at baseline and at follow-up reported significantly lower HRQoL values than boys (between subjects P < .001). After adjustments for potential confounders, regression analyses showed significant cross-sectional associations between cardiorespiratory fitness and HRQoL both at baseline (B = 0.095; P = .023) and at follow-up (B = 0.090; P = .012). ANCOVA showed that adolescents whose cardiorespiratory fitness decreased over time exhibited lower scores of HRQoL at follow-up, compared to those with persistent high cardiorespiratory fitness; this held after adjustments for age, sex, socioeconomic status, and pubertal stage. Conclusions: Changes in cardiorespiratory fitness during adolescence were associated with HRQoL over a 2-year period. This study suggests that improving cardiorespiratory fitness could be an important strategy in improving the HRQoL of adolescents.
