A study of relation between physical growth and sexual maturity in girls--V.

The findings indicate that sexual maturity would be initiated only after the attainment of requisite morphological body size such as weight on an average nearly 27 kg and height of 137 cm, irrespective of age and SES. The girls from LSES were chronologically older throughout the span of pubertal growth. However, they took lesser time to reach full maturity after the attainment of mid-pubertal growth compared to USES. Menarche appeared after attaining about a minimum weight of 35 kg, height of 143 cm and bicristal breadth is 24 cm. Its appearance followed the attainment of peak height velocity and 3rd developmental stage of breast and/or pubic hair. It, however preceded the attainment of weight and bicristal breadth peak velocities.
