Abstract

Objectives.: To assess the concordance between self-assessment of pubertal development with the Tanner scale performed by adolescents compared to the assessment performed by a trained physician.

Materials and methods.: As part of the SIMAC project, data was collected on 244 adolescents. At baseline, we included an anthropometric and pubertal development assessment, with a self-assessment by the participants.

Results.: We included 229 teenagers from 12 to 17 years old. The agreement between the self-assessment and the clinical evaluation with the Tanner scale presented an 88.3% agreement and a weighted kappa coefficient of 0.554. The self-assessment in women showed a good agreement ( kappaweighted=0.653) and in men a moderate agreement (kappaweighted=0.464). The only variable with a significant influence on the agreement ability was gender; the disagreement probability in males was 63% greater than in females, regardless of age, height, or weight (95% CI: 1,18-2, 26).

Conclusions: . Self-assessment was not accurate enough to replace medical examination, especially in males. More research is needed on this subject considering the impact that self-assessment of sexual development could have.

Objetivos.: Evaluar la concordancia entre la autoevaluación del desarrollo puberal mediante la escala de Tanner realizada por adolescentes, comparado con la evaluación efectuada por un médico entrenado.

Materiales y métodos.: Los datos de 244 adolescentes fueron recolectados como parte del proyecto SIMAC. En la línea de base incluimos una evaluación antropométrica y del desarrollo puberal, con una autoevaluación por parte de los participantes.

Resultados.: Incluimos 229 adolescentes de 12 a 17 años. La concordancia entre la autoevaluación y la evaluación clínica de la escala de Tanner presentó un acuerdo obtenido de 88,3% y un coeficiente kappa ponderado de 0,554. La autoevaluación en mujeres demostró una concordancia buena (kappapond=0,653), y en varones una concordancia moderada (kappapond=0,464). La única variable con una influencia significativa sobre la capacidad de acuerdo fue el sexo; la probabilidad de desacuerdo en los varones fue 63% mayor que en las mujeres, independiente de edad, talla y peso (IC 95%:1,18-2,26).

Conclusiones.: La autoevaluación no fue lo suficientemente precisa para reemplazar el examen médico, sobre todo en los varones. Se requieren más estudios en relación con este tema, reconociendo el impacto que podría llegar a tener la autoevaluación del desarrollo sexual.
