ABSTRACT

Objetivo: El objetivo de este estudio es analizar la secuencia de la pubertad en los niños y las niñas de nuestra área sanitaria. Métodología: Trescientos diez niños y niñas sanos de raza caucásica participaron en este estudio prospectivo. Se recogieron las siguientes variables: peso de recién nacido (PRN), peso (kg), talla (cm) e índice de masa corporal (IMC) (%) en los diferentes estadios puberales, edad ósea al inicio y final de la pubertad el tiempo de duración de la pubertad y el crecimiento durante el mismo. Resultados: Media (DE): la pubertad se inicia en los niños a los 12,4 años (1,5) con edad ósea de 11,9 años (1,3) y se alcanza el Tanner V a los 15,6 años (1,5) con edad ósea de 14,5 años. En las niñas la pubertad empieza a los 10,1 años (1,4) con edad ósea de 10,3 años (1,1), y la menarquia a los 12,0 años (1,3) con edad ósea: de 13,2 años (0,9). El tiempo de crecimiento hasta el Tanner V en los niños es de 3 años (1,2) con un crecimiento total de 19,5cm (7,6) En las niñas el tiempo de pubertad hasta la menarquia es de 2,5 años (1,1) con un crecimiento total de 15,7cm (5,0). Los niños que comenzaron la pubertad antes de los 11 años mostraron un crecimiento mayor durante la misma 27,3cm (7,9) que los que lo iniciaron después 17,4cm (5,9) (p<0,0001) y crecieron durante más tiempo 3,9 años (1,2) versus 2,7 (1,1) (p<0,001). De igual forma las niñas que comenzaron la pubertad antes de los 9 años crecieron más 19,7cm (4,3) que las que lo hicieron después 14,4cm (4,5) (p<0,0001) y más tiempo 3,1 años (0,8) versus 2,3(0,9) (p<0,0001). Conclusión: Los niños inician la pubertad a edades similares que otras poblaciones españolas, sin embargo en las niñas se adelanta, así como la menarquia. La edad ósea es acorde a la edad cronológica en ambos sexos al inicio de la pubertad pero no al final, adelantándose en las niñas. La duración de la pubertad y el crecimiento durante la misma es mayor en aquellos que inician la pubertad antes, para ambos sexos. No se encontró ninguna relación entre el IMC y el PRN con el inicio de la pubertad (AU)


Objective: Changes in the onset of puberty have been reported in the last few years. The aim of this study is to determine pubertal trends in boys and girls. Method: Longitudinal study was conducted on 310 caucasian children. We analysed birth weight (BW), weight (kg), height (cm) and body mass index (BMI) (%), bone age, duration of puberty growth and pubertal height spurt. Results: For boys the mean age at stage 2 was 12.4 (1.5) years with a bone age of 11.9 (1.3) years, and stage 5: 15.6 (1.5) with a bone age of 14.5. Mean age (years) (SD) for girls stage 2 was 10.1 (1.4), with a bone age of 10.3 (1.1). Age at menarche was 12.0 (1.3), with a bone age of 13.2 (0.9). Duration of puberty growth for boys was 3 years (1.2), and for girls 2.5 years (1.1). Pubertal height spurt in boys was 19.5cm (7.6) and for girls was 15.7cm (5.0). Girls with puberty onset<9 years of age show a greater pubertal height gain (19.7cm (4.3)) than girls >9 years of age [14.4 (4.5) (P<0.0001)] and a longer period of pubertal growth 3.1 years (0.8) versus 2.3 (0.9) (P<0.0001). Boys with puberty onset <11 years of age had a greater pubertal height gain [27.3cm (7.9)] than boys > 11 years of age [17.4 (5.9) (P<0.0001)] and a longer period of puberty growth of 3.9 years (1.2) versus 2.7 (1.1) (P<0.001). Conclusions: Boys presented secondary sex characteristics at the same age as other studies, but the girls reached puberty and menarche at a younger age than previous studies in the Mediterranean area. Bone age correlates with chronological age for both sexes at the beginning of puberty but not at the end. Early onset of puberty was associated with a greater pubertal height gain and a longer period of pubertal growth. There was no correlation between BW or BMI with onset of puberty (AU)
