Menarcheal was recorded by recall method who menstruating at beginning study prospectively whose onset after initiation study. Body fat (%) estimated using TSFT. Results: The LSE not only had lower attained height, but also significant difference (p < 0.05) menarcheal (15.4 yr) as compared HSE (12.1yr). Although social differences delayed occurrence event chronological age, time between peak (PHV) remained similar (1.5 irrespective class. mean weight menarche, level (but individual level), around 38 kg both classes, onset. Further represented point maximum deceleration acceleration classes. Conclusion: Our data indicated partial support critical hypothesis suggested these limits vary community community. analysis revealed rather than absolute values fat, are significance with regard menarche.
