Abstract

Over the last few centuries there has been a trend of early onset of menarche is associated with better nutrition. Several studies have found a decrease in age of menarche is accompanied by an increase in BMI. Rapid onset of menarche also found in children who are obese than lean. Low BMI show no fulfillment of nutrients that can affect the growth and development speed in children. The aim of this cross-sectional study is to determine the relationship between BMI with age at menarche. This research was conducted using 77 female students who were selected through proportional random sampling technique using questionnaires and interviews. The data were analyzed using SPSS with the Spearman correlation test. The results of this study are the average BMI is 19.93 (± 3.162) kg / m2, and the average age of menarche is 11.75 years with 9 years old as the youngest and the oldest 14 years. We find a correlation between BMI at the age at menarche, with p = 0.000 (p < 0.05) and r = -0.429. The higher the BMI, the more rapidly menarche occur. Keywords : BMI, age at menarche
