“…5 This decline could be due to improvement in nutritional status and environmental changes. 6 The mean age of menarche in this study was higher compared to studies in Kuwait15 (12.41 years old) and United States 2 (12.32 years old), but was lower than the study in South Korea 3 (13.1 years old). The differences might be due to sexual maturity variation by race, ethnicity and nutritional status.…”

Background: The decline of age at menarche has been reported in several countries, it occurred because of genetic, ethnic, and socioeconomic improvement in nutritional status and environment. The improvement of nutritional status has occurred globally all over the world including in Indonesia. One of the measuring tools in nutritional status is body mass index (BMI). The objective of the study was to assess the correlation between BMI and age at menarche. Methods: A cross-sectional study was carried out among girls aged 9-15 years old in Jatinangor, from May-November 2013. The sample of this study was chosen with cluster random sampling. Age at menarche information was collected through a questionnaire. Body mass index was calculated from measurement of body weight and height. Data was analyzed using Spearman correlation test. Results: Out of three hundred and sixty nine subjects participating in this study, sixty seven were included in the inclusive criteria. According to the classification of BMI of underweight, normal, overweight, and obese, there were 1, 55, 8, and 3 persons, respectively. Mean of BMI was 19.04 and mean age at menarche was 12.72 years, which showed a non significant result (r=-0.013; p= 0.458). Conclusions: Age at menarche was not correlated with BMI. [AMJ.2015;2(4):

The time of first menarche is an important milestone in female sexual maturation. Some studies have shown that menarche is occurring earlier in previous decades. The onset of menarche depends on many factors including genetic, social, and environmental and ethnicity. In recent years, obesity defined the factor in menarche age. The possible contribution of prenatal factors has not been adequately explored. Data on the timing of menarche among Armenian girls is not available. The present study examines the menarche age among adolescent girls in Yerevan city.Dates regarding gestational age, birth weight and height, chronological age of onset of menarche, anthropometric dates of menarche time were collected.Mean age of onset of menarche was 11.3 ± 0.8 years old for the total group of 450 girls. Age of menarche was negatively correlated with weight at menarche and positively correlated with height. There is a reversal relation between age of menarche and Body Mass Index (BMI) at menarche. All of the analyses show a consistent and significant relationship of infant size at birth to age at menarche. Girls who were relatively long and light at birth attain menarche earlier.

“…Examples of the environmental factors include nutritional status, adipose tissue composition, and socioeconomic status. 2 From 1950's to 20th century, the average age at menarche was 15 to 17 years old. However, in the current generation, the mean age at menarche can range from 13 to 16 years old.…”
