To determine the association between body mass index and abdominal circumference and the age of onset of menarche in schoolchildren between 8 and 16 years of age. MATERIAL AND METHODS: Using a cross-sectional analytical design, we reviewed 120 schoolchildren divided into two groups; Postmenarche G1 and premenarche G2 comparing BMI and abdominal circumference. RESULTS: A total of 120 female schoolchildren between 8 and 16.99 years of age were studied, with an average of 12.14 SD 2.35 years of age, mean BMI 19.94 kg/m2, SD 4.06. Menarche occurred between 9 and 15 years the mean age of menarche was 11,206 SD 1.03 years: The mean BMI was lower in the premenarche group 18.4902kg/m2 ± 3.98 vs 20.9917 ± 2.97 post bmenarche respectively, a significant p=0.00. The mean abdominal circumference was 66.383 ± .20 vs 72.4667 ± 6.39 in the pre- and post-menarche group, difference 6.1cms p=0.00. There is a low indirect correlation, Pearson's correlation coefficient of -0.087 for BMI (p=0.510) and -0.038 for abdominal circumference (p=0.771 Table No4: 66.95% of schoolchildren with obesity (BMI>P95) had early menarche, compared to 46.15% of non-obese students. The risk of early menarche due to obesity is non-significant: OR=1.429 (0.767-2.662), p=0.164; OR=2.429 (1.767-2.662) p=0.016. The risk of early menarche due to central obesity is significant OR=2.429 (1.767-2.662) p=0.016 and OR ajustado 1.36 (1.08-2.18) p=0.033 y el peso con OR=1.89 (1.78-2.04) p=0.043. CONCLUSIONS: There is a low correlation between BMI and abdominal circumference with age at menarche; schoolchildren who had menarche have higher levels of BMI and abdominal circumference, central obesity is a risk factor for early menarche.
