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.
研究结果表明，性成熟只有在达到必要的身体形态尺寸后才会开始，比如平均体重接近27千克、身高137厘米，而与年龄和社会经济地位无关。来自低社会经济地位（LSES）的女孩在整个青春期生长过程中按时间顺序年龄更大。然而，与高社会经济地位（USES）的女孩相比，她们在青春期中期生长达到后达到完全成熟所需的时间更短。月经初潮在达到约最低体重35千克、身高143厘米和双髂嵴间径24厘米后出现。它在达到身高速度峰值以及乳房和/或阴毛的第三个发育阶段之后出现。然而，它先于体重和双髂嵴间径峰值速度的达到。
