Abstract
This study considered the concordance of self‐assessment and physician assessment of sexual maturity status; breasts, and pubic hair in girls, and genitals and pubic hair in boys. The subjects were Brazilian children, youth and young adults, 174 females and 178 males, 6–26 years of age. Each subject evaluated his/her level of sexual maturation and then was examined by a physician. The sexual maturity ratings of the subjects and physicians were compared. Overall, the results showed moderate to high concordance (60.9–71.3%) for both assessments of secondary sex characteristics; better concordance was found for pubic hair (69.7–71.3%) than for the breasts or genitals (60%). Age did not appear to influence the accuracy of self‐evaluation; rather, accuracy was more dependent on stage of maturation of the subject. Correlations between self‐ and physician assessments, and replicate self‐ and physician assessments were relatively high.
