Evidence between age at menarche and endometrial cancer risk have been controversial. Therefore, we conducted a meta-analysis of prospective studies to analyze the aforementioned association. Relevant studies were identified by searching PubMed and EMBASE databases until the end of June 2015. A random-effects model was used to estimate summary relative risks (RRs) and 95% confidence intervals (...

BACKGROUND Age at menarche is a significant indicator of growth and sexual maturation in girls. During adolescence, anthropometry provides a tool for monitoring and evaluating the hormone-mediated changes in growth and reproductive maturation. OBJECTIVES We aimed to examine the anthropometric status of pre- and post-menarcheal Nigerian adolescent girls attending senior secondary schools. MA...

OBJECTIVE This study aimed to evaluate the mean age of menarche, its secular trend in Korean women, and the relationship between malocclusion and the rate of skeletal maturation, as defined by menarcheal age. METHODS We retrospectively collected data on menarcheal age from 931 Korean women born during 1961 - 1997. Subjects were divided by the malocclusion type and birth-year decade into 3 and...

In a cross-sectional retrospective study of 2087 Ghanaian school girls in various educational institutions in the Kumasi district, Ashanti region, Ghana, the mean menarcheal age was found to be 13.98 +/- 1.42 years. Differences in the menarcheal age of the girls was found to be significantly correlated to social class, parents ethnic origin, educational institution and home living area (P = 0.0...

BACKGROUND Menarcheal age is a sensitive indicator of environmental conditions during childhood. The aim of study is to determine the age at menarche and growth status in adolescents in a rural area of Tarka, Wannune, Nigeria. METHODS Data on 722 female students (aged 12-18 years) were collected in February 2009. Height and weight were measured. Body mass index (BMI; kg m-2) was used as an in...

OBJECTIVE To assess secular trends in menarcheal age between 1973 and 1994 and to determine whether childhood levels of height, weight, and skinfold thicknesses can account for racial (white/black) differences in menarcheal age. METHODS Data from 7 cross-sectional examinations of school-aged children, with menarcheal age obtained through interviews, were used for both cross-sectional (11 218 ...

The subjects of the study were 85 Indian sportswomen from Delhi and the states of Uttar Pradesh, Punjab and Gujarat, and included outstanding players of cricket, hockey, kho-kho and table-tennis, who were winners of university, state or national championships. A sample of 77 subjects selected at random was used as the control. The recall procedures suggested by Damon and Bajema (1974) were used...

PRIMARY OBJECTIVE To show that socio-economically dependent cultural bias distorts results of the status quo method of estimating age at first menstruation. METHODS Questionnaires asking for menstrual status and the recalled age at menarche were distributed to approximately 1000 Javanese girls who attended junior and senior high schools in Malang. Age of participants ranged from 11.98 to 18.8...

Menarcheal age was estimated for 287 (188 Black; 99 White) urban South African girls born in Soweto-Johannesburg in 1990. The median menarcheal age for Blacks was 12.4 years (95% confidence interval (CI) 12.2, 12.6) and 12.5 years (95% CI 11.7, 13.3) for Whites. Data from six studies of menarcheal age, including the current study, were analyzed to examine the evidence for a secular trend betwee...
