Age of puberty in the Burmese male and female

ABSTRACT

A total of 1,510 school boys (ages ranging from 9 to 18 years) and 1,770 school girls (ages ranging from 10 to 19 years) were examined to determine the age of puberty in the Burmese. The median age of adolescence for Burmese boys was found to be 4.67 years. The mean age of menstruation in girls was found to be 12.4 years (S.D. 1.71). Results were compared with those obtained by researchers in other countries. That onset of puberty in tropical climate occurs two years later than in temperate climate, as popularly held by many medical authorities, is still open to criticism.
