BACKGROUND Menarche is a milestone for adolescent girls. The timing of menarche is influenced by genetics, social status and nutritional status (e.g., height, weight and body mass index [BMI]) and impacts future health (e.g., obesity and breast cancer). There have been many studies on trends in age at menarche among adolescent girls in China, but few have investigated associations between growt...
OBJECTIVE To compare the age at menarche obtained by recall method according to the time elapsed since the event, in order to verify the importance of the recall bias. SUBJECTS AND METHODS Were evaluated 1,671 girls (7-18 years) at schools in Campinas-SP regarding the occurrence of menarche by the status quo method (menarche: yes or no) and the recall method (date of menarche, for those who m...
Menarche is the first period of menstruation in woman reproduction cycles. Several epidemiology study revealed the earlier onset of age of menarche. Better nutritional status, e.g. overweight-obese, is considered as one factor contributes to this condition. We want toknow the association between overweight-obese girls and age of menarche. A cross sectional study was performed in SDN 1 Kleco Sur...
AIM To present a visual representation of changes in body composition, leptin, insulin, estradiol and follicular stimulating hormone (FSH) levels in relation to menarche in girls. METHODS Participants were a subset of healthy girls (n = 108) enrolled in a longitudinal study of growth and development conducted at the General Clinical Research Center at the Massachusetts Institute of Technology...
BACKGROUND The age at menarche in the Thai population has not been determined since 1997. This study recruited adolescents in Bangkok Metropolis to determine the age at menarche and its associations with health and socioeconomic status. METHODS This cross-sectional study used a two-step stratified sampling strategy to recruit 1,020 female students, aged 10-16 years, from schools in Dusit dist...
OBJECTIVE Recent studies have demonstrated that earlier menarche is associated with increased risks of prediabetes and diabetes in white women; however, the associations have not been fully explored in Asian populations. We investigated the associations between age at menarche and prediabetes and/or diabetes in Korean middle-aged women. METHODS This was a cross-sectional study of 2,039 premen...

African-American (AA) women have earlier menarche on average than women of European ancestry (EA), and earlier menarche is a risk factor for obesity and type 2 diabetes among other chronic diseases. Identification of common genetic variants associated with age at menarche has a potential value in pointing to the genetic pathways underlying chronic disease risk, yet comprehensive genome-wide stu...
OBJECTIVE The attitudes of girls regarding menarche vary according to their cultural backgrounds. Asian girls may hesitate to discuss menarche. Computer-assisted self-administered interviewing (CASI) is considered a valid and effective tool for investigating the timing of menarche; however, the validity of self-reported menarche data from CASI in Chinese culture is currently unknown. We aimed t...
