Furthermore in relation to early age ofmenarche has been identified as a risk factor for breast and endometrial cancer due to the increased exposureto estrogen. Hence, it is important to give awareness in adopting healthy eating habits and involving in dailyphysical exercise.Aim: To measure the body mass index in adolescent girls and correlate between the age of menarche andbody mass index in adolescent girls.Methodology: This is cross-sectional study with a sample size of 200 female students between the age groupof 17 – 19 years attending different courses (MBBS, BDS, AHS and BPT) in Melmaruvathur AdhiparasakthiInstitute of Medical Sciences and Research, Melmaruvathur. An informed consent will be obtained fromthe participants. A dietary history will be taken by questionnaire. The anthropometric measurements forcalculating the BMI will be measured using calibrated instruments.Result: The results of this study the statistically significant were seen among the age of menarche andthe BMI, pearson chi-square is 21.876 and p value is 0.009 and also statistical significant was seen whencompared regularity of periods with BMI, pearson chi-square is 10.018 and p value is 0.01. There was nostatistical significant when compared waist-hip ratio with age of menarche and regularity of periods.Conclusion: The age of menarche had a tight connection with BMI. Increase in BMI causes early age ofmenarche. So having increased body fat, increased body weight, high intake of protein, high-calories foodsand sedentary life style causes early age of menarche in young healthy girls.
