Menarche has occurred in 20.9% of Indonesian women under the age of 12 years. The study design was cross-sectional with a sample of 90 children in grades 5 and 6. The sampling technique used non-probability sampling, data analysis used the Chi-Square test (α=0.05). Variables related to the incidence of early menarche are lifestyle (P-value=0.004, OR=9.008), BMI status (P-value=0.007, OR=8.042), variables not related to early menarche, namely: level of religious knowledge related to menarche (P-value=1.000, OR=0.000).
