Using factor analysis, both Ellison and Elizondo found a relationship between age at menarche and height rather than weight velocity, supporting the more. The significant positive association was between age at menarche and height. Height of students with menarche at an earlier age was less (P<0. 05). There was . Second, the relation between age at menarche and height was estimated by linear regression models, adjusted for age at enrollment between.

It has been suggested that girls who undergo menarche early may have a longer period of a positive energy balance or many endo-neurocrine components affect the speed of sexual maturation and body fat accumulation Thus, early menarcheal age causes precocious shutdown of the plates, and girls who undergo menarche early have a shorter final adult height compared to late menarche groups The mean menarche age was found to gradually decline, while the age at beginning of regular menstrual cycle increased steadily 16 These tendency may be due to a change in diet consumption to thin figure and an increase in physical activities, psychological stress affecting menstrual cycles The most often demonstrated menstrual disorders are poly-menorrhea, oligomenorrhea, and dys-menorrhea These are more frequent among younger adolescents and reach to less frequent years after beginning of menarche There have been many studies on the impacts of height, weight, and body structure on the menarche age.

However, there is argument for the roles of those components. In this study, we focused on height, weight, body mass index BMImenstrual patterns, and menarche age in a large number of late adolescent girls in order to elucidate the influence of menarcheal age on anthropometric indices and menstrual irregularity in late adolescents. Materials and methods 1.

Subjects This study was performed from June to October at seven girl's high schools which approved the survey and including some female college students in Seoul, Korea. The inclusion criterion was adolescent girls who underwent menarche more than 2 years prior to the survey. A total of 4, females, aged years old, were enrolled in the study and categorized into three groups according to their menarcheal age: Methods The survey tool was a self-report questionnaire that included questions on anthropometric data height, weight, and waist circumferencemenarcheal age, menstrual irregularity, and frequency of menstruation per year.

Introduction Menarche age is an important indicator of reproductive health of a woman or a community.

In industrial societies, age at menarche has been declining over the last years with a secular trend, and similar trends have been reported in some developing countries [ 1 ]. Puberty is a natural developmental issue, common to nutrition, health and well-being as well as socioeconomic both man and woman [ 2 ].

Puberty is common to the adolescence and a minimum weight requirement for the development of secondary sexual characteristics is starting with the menstruation. On the other hand, studies lead to the total differentiation of male and female; also, show that the childhood malnutrition can delay the onset the final height and posture of the male and female of menstruation but does not prevent its occurrence. Adolescents are determined in this period.

Puberty is the complex process by which children develop secondary sexual characteristics and reproductive competence. Normal puberty is initiated centrally, with gonadal function being driven by increased gonadotropinreleasing hormone GnRH and gonadotropin secretion. Among other factors, adequate nutritional status appears to be requisite for the central initiation of puberty [ 3 ]. BMI are more likely to have thelarche between ages 8.

Body mass Index increased progressively from 13 years to 19 years of age where overall increase was 1.

Subjects are years adolescent girl. In the analysis of the growths among subjects in this study, we consider 2 time scales: After controlling the heterogeneity of individuals' birth heights and growth rates for the chronological age among girls, the average change in height for chronological age adjusting for menarcheal age was estimated based on all subjects.

The average increase in height per year of chronological age for those aged 11 years or older at menarche is 1 cm more than the increase for those aged younger than 11 years at menarche. Although changes in growth rates before and after menarche based on the relationship between height and chronological age is statistically significant, the magnitude of the slope changes before and after menarche are not more than 0.

In addition, growth patterns between those younger than 10 years at menarcheal onset and those with menarcheal onset between ages 10 and 11 years are not significantly different.

Growth in height with respect to the time from menarche adjusting for the same school based on subjects who had menarche during the study period is given in Table 2.

However, the results based on the mixed-effect model analysis for weights and BMIs did not show the significant pattern between the weight or BMI velocity and age at menarche as the patterns exhibited in heights. The results from the empirical smoothing analysis and the mixed-effects model analysis are consistent with each other.

Two time scales, chronological age and time from menarche, are considered in the analysis. According to the chronological age scale, the height velocity for subjects with later menarche is more rapid but there is no obvious growth spurt for height associated with menarche.

In the height analysis with the time from the onset of menarche scale, we found that the peak of height velocity was reached 1 year prior to menarche. This study did not find any effect of weight on the onset of menarche as suggested by Frisch and Revelle 12 and Frisch and MacArthur. It is possible that the nutritional status in Taiwan is generally good and there may be no differences in fat accumulation among school-aged girls in Taiwan. This study has the following strengths and contributions: Most previous studies 1521 - 24 were cross-sectional.

On the other hand, some longitudinal studies 12131718 suffered from small sample size.

The study subjects were selected from 3 elementary schools in Taipei City and 5 in Taipei County. Though the selection was not random because of administrative concerns, the socioeconomic status and geographic distribution of the schools were wide enough to represent elementary schools in the Taipei area. The effect of loss to follow-up was negligible. Second, the identification of the onset of menstruation is clear, was easy for each subject to identify, and was double-checked.

Height and weight records were measured by school nurses at school health centers through standard criteria and thus were reliable. Also, height and weight were measured independently, while neither the subjects nor their teachers had previous knowledge of height, weight, and the onset of menarche. There would be minimal possibility for information bias. In the statistical analysis, we made 3 contributions:
