Correlation between Body Mass Index and Age at Menarche
Althea Medical Journal, 2015
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.
Relationship of menarche age with anthropometric profiles
South Asian Journal of Food Technology and Environment, 2017
Menarche (first menstrual period) is the major component in the reproductive life of women. The beginning of the same determines the start up of natural reproduction process in the women's life. As this biological trait has an important cultural, social and epidemiological implication. Increasing attention has been recently devoted by scientists to understanding the causes of age variations in the timing of this event. The present cross-sectional study was designed to investigate the relation between anthropometric parameters among the adolescent girls and age at menarche. 120 school adolescent girls aged 11-14 years old were selected by purposive sampling. Anthropometric examination including height(cm), weight(kg), BMI(kg/m 2), percent body fat (%BF), body frame size (BFS), waisthip ratio (WHR) were measured and information on age of menarche were collected. The result showed the mean age of menarche was 12.58. There were a significant correlation between age at menarche and weight, height, BMI, %BF & BFS. The significant correlation showed that the higher the BMI, the lower the age of menarche. The menarche age is experiencing a decreasing trend. BMI can be considered as key factor for early menarche. However, it must be recognized that such developments will be followed by overweight, obesity, which all require a constant supervision.
Identifying menarcheal age and its association with body mass index in young Saudi females
Saudi Medical Journal
Objectives: To explore the relationship of menarcheal age with body mass index (BMI), to find mean menarcheal age in Saudi population and compare it with global data, and to create awareness in health science students on harmful effects of obesity. Methods: A cross-sectional study carried out between February 2015 and February 2016 on 744 health sciences students of Immam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia aged 18-21 years. Weight and height was measured, and subjects were categorized into 2 groups on the basis of BMI: normal and underweight (BMI ≤24.9), and over weight and obese (BMI ≥25). The data analyzed was preformed by Statistical Package for Social Sciences version 20.0 (IBM Corp, Armonk, NY, USA). Results: Mean menarcheal age of subjects was 13.1 years. Early menarche was observed in 35.6% of the students. Of the 21.7% overweight/obese group, 45.6% reported early menarche. The early menarcheal group had significantly higher BMI compared to late menarcheal group (p=0.021). Significant negative correlation was found between BMI and menarcheal age (p=0.0006). Conclusion: The present study indicates a downward secular trend in the menarcheal age of the Saudi population. Moreover, a negative correlation between BMI and menarcheal age was also documented.

Objectives: The age of menarche can be different among girls based on region, ethnic, and some individual factors such as body mass index (BMI). Little is known about the menarche age in Kurdish girls. This study was conducted to determine the menarche age and its association to BMI and socioeconomic status among Kurdish schoolgirls. Methods: This was a cross-sectional study conducted on 400 schoolgirls from different secondary and high schools in Sanandaj, northwest of Iran. Multi stage sampling was used to select the study samples. Data were collected using a checklist, which included demographic information and other variables under investigation. SPSS version 20 was used for data analysis. Independent sample t-test, one-way ANOVA, and logistic regression were used for data analysis. The significance level of the tests was considered to be 0.05. Results: The mean and standard deviation (SD) of menarche age was 12.87 ± 1.17 years. About 60.3% of girls had normal BMI and 31%, 6.8%, and 2% of them were underweight, overweight, and obese, respectively. There was a significant relationship between higher BMI (P = 0.02) and menarche age. Based on multivariate analysis, the chance of early menarche in children with higher BMI (≥ 25) was significantly 3.57 times higher than others (P = 0.004). There was no significant relationship between socioeconomic status, physical activity, and birth season, attitude towards menarche, nutritional status, and number of brothers with age of menarche. Conclusions: The results showed a significant relationship between menarche age and BMI. The age of menarche in our region was also different compared to other regions of the globe. The findings of the present study can be used by health policy makers for planning and conducting the interventional programs related to menarche in girls.
Association of age at menarche with body mass index and waist-hip ratio
International Journal of Medical Science and Public Health, 2016
Background: Menarche is the first onset of menstruation. Current trend shows decrease in age of menarche. There is strong evidence that the increasing rate of obesity can be attributed to decreasing menarche age. Objective: To analyze the relation between age at menarche and anthropometric parameters such as body mass index (BMI) and waist-hip ratio. Materials and Methods: This cross-sectional study was conducted on 170 adolescent girls aged between 18 and 25 years. The participants were given a questionnaire that included data on birth date, age of menarche, parent's education, ethnic background, and food habits. Height and weight were measured, and BMI and waist-hip ratio was calculated. The participants were divided into three different categories based on BMI values. Statistical analysis was carried out in SPSS software, version 16.0. The data were analyzed using descriptive statistics and one-way ANOVA. Pearson's correlation coefficient was used for correlation studies. Result: Majority of the participants showed a normal BMI, and no significant correlation could be drawn between age at menarche and BMI (p > 0.05). There was no significant relation between waist-hip ratio and menarche too. Conclusion: Relation between BMI and age at menarche was not significant in this study. The abovementioned findings suggest that there are other factors also that contribute to early puberty. Data were also required for amount of energy intake at the time of puberty, especially those foods that contain hormones such as estrogen and antiestrogens. Other important factors such as ethnic and cultural background, socioeconomic status, supportive family, and lifestyle factors also play a very important role in determining the age of menarche.

2017
Background Menarche is a substantial and important period in the health of adolescent girls’, and has a significant impact on their health in the upcoming years. Accordingly, in this study, we aimed to not only determine the average age of menarche among high school girls in Qom city, but also to examine the effect of some factors on onset age of menarche. Materials and Methods In this cross-sectional study, a researcher-made questionnaire was presented to 400 girl students from six high schools in Qom city-Iran, including questions about individual characteristics, onset age of menarche in the participant and her mother, and some other indicators related to menarche. Data were analysis using SPSS version 16.0 software. Results From 400 distributed questionnaires 370 (92.5%) were filled correctly and completely. The findings of this study showed that the average age of menarche in girls has been 12.3 ± 1 year and 90% of the subjects had experienced menarche before the age of thirtee...

Early onset of menarche has been shown to be associated with breast cancer and ischaemic heart disease. Studies on age at menarche of the Malaysian population are poorly documented. This study aimed to determine the influence of anthropometric and socio-demographic factors on the age at menarche of university students in Malaysia. Data were obtained in 2010–11 from 961 students between the ages of 18 and 25 years from the University of Malaya using stratified sampling, and multiple regression analysis was applied. Sixty-three per cent of students reached menarche at the age of 12 or 13 years, with the mean and median of age at menarche being 12.45±1.17 and 12.01 years, respectively. Menarcheal age was positively associated with height (p<0.05) and negatively associated with BMI (p<0.001). Students from urban areas attained menarche earlier than those from rural areas (p<0.05). Students from small-sized families attained menarche earlier than those from larger families (p<0.05). First-born students experienced menarche earlier than those who were seventh-born or later. Obese and overweight students reached menarche earlier than students who were underweight or of normal weight (p<0.01). The variations in age at menarche among the Malaysian ethnic groups were statistically insignificant. The results suggest that heavier and first-born students from small families are more likely to attain menarche earlier than their counterparts.

Collegium antropologicum, 2015
The aim of this paper is to analyse age at menarche in Tanzanian girls for associations with body composition and selected somatic indices. The study included 97 girls (71 post-menarche and 26 pre-menarche). Measurements were taken of body height, body weight, waist and hip circumferences. Body composition was analysed for percentages of body H2O, fat, and muscle. The girls' nutritional status and body fat distribution were assessed using the following somatic indices: BMI, WHR (Waist-to-Hip Ratio) and WHtR (Waist-to-Height Ratio). For the post-menarcheal group N=71, backward stepwise multiple regression analysis was performed. Average age at menarche calculated using the recall method for N=71 was X=14.29 years, calendar age X=15.92 years. More than half (57.69%) of the girls in the pre-menarche group had not reached the body weight of 48kg, whereas in the post-menarche group they accounted for 32.39%. As many as 97.18% of the post-menarche girls had body fat content of 22%, co...

Increase of childhood obesity prevalence and rapid changes in socioeconomic status resulted in a decline in age at menarche, which contributes, to a number of diseases affecting women's future health. The objective of this study is to assess the mean age at menarche in girls of ages 9-16 and observe its relationship with their body mass index and other covariates in Riyadh, Saudi Arabia. Materials and Methods: A cross-sectional study was conducted among 304 female students of both private and governmental schools in Riyadh, Saudi Arabia, during March-May 2013. Data on demographics, socioeconomic status, physical activity, diet, and age at menarche were collected from students and their mothers, using self-administered questionnaires. Physical examinations were conducted to collect the anthropometric measurements. Results: Out of 304 students with a mean age (SD) of 12.52 (2.08), 165 (54.3%) attained menarche. Mean menarcheal age (SD) for the girls was 12.08 (1.28). The mother's mean age at menarche was positively correlated with their daughters (r=0.411, P<0.001). There was no signifi cant correlation between BMI and age at menarche (P>0.05). Governmental school students attained menarche at a higher age (12.34) than private school students (11.59), and the difference between them was statistically signifi cant (P<0.001). Conclusion: Schoolgirls in our study attained menarche at an early age with a mean menarcheal age of 12.08 years. Our data follows the globally and regionally observed declining trends of age at menarche. When assessing BMI as an infl uencing factor of onset of menarche, our results showed no correlation. Further longitudinal studies are encouraged to monitor factors infl uencing the onset of menstruation, in order to prevent the potentially adverse consequences of early menarche.

Background: Evidence suggests that early menarche is positively associated with adiposity in adulthood. However, it is important to assess whether this association is due to early menarche or to the association of adiposity in late childhood with age at menarche. We evaluated the association between age at menarche and body composition in adolescence and adulthood, among subjects who have been prospectively followed in two Brazilian birth cohort studies. Methods: In 1982 and 1993, the hospitals births in Pelotas were identified, and these subjects have been followed for several times. Information on age at menarche was obtained from the women (1982 cohort) and their mothers (1993 cohort). At 30 and 18 years, the following body composition measures were evaluated: body mass index, waist circumference, fat-free mass index and fat mass index measured by dual-energy x-ray absorptiometry, and thickness of the abdominal visceral fat layer measured by ultrasound. The analyses were adjusted for: birth weight, maternal pregestational weight, gestational age, family income, household score index, maternal schooling, weight-for-height z-score at 4 years (1982), and body mass index at 11 years (1993). Results: At 30 and 18 years, 2045 and 2092 women were evaluated, respectively. The prevalence of early menarche (≤11 years of age) was 24.7 % in the 1982 and 27.6 % in the 1993 cohort. In the 1982 cohort, early menarche was positively associated with all body composition variables compared to those with late menarche (≥14 years of age) even after adjusting for confounders (fat mass index: 2.33 kg/m 2 , 95 % Confidence interval: 1.64; 3.02). However, in the 1993 cohort, after adjusting for body mass index at 11 years, the regression coefficient for the association with fat mass index decreased from 2.2 kg/m 2 (95 % Confidence interval: 1.7; 2.6) to 0.26 (95 % Confidence interval: −0.08; 0.60). Conclusions: The association between age at menarche and body composition in adulthood is strongly explained by pre-pubertal adiposity.
