BACKGROUND: The aim of this study was to examine the association between early menarche (<12 years) and non-alcoholic fatty liver disease (NAFLD) in premenopausal women and to explore whether it is mediated by adult obesity and insulin resistance. METHODS: We analyzed data of premenopausal women, aged 15 or older, from the Korea National Health and Nutrition Examination Survey (2007-2009). We divided the women into 3 groups: early menarche, reference (12.00-15...

It has been suggested that successful young gymnasts are a highly select group in terms of the physique. This review summarizes the available literature on elite female gymnasts' anthropometric characteristics, somatotype, body composition and biological maturation. The main aims were to identify: (i) a common physique and (ii) the differences, if any, among competitive/performance levels. A systematic search was conducted online using five different databases. Of 407 putative papers, 17 fulfilled all criteria and were included in the review...

BACKGROUND: Earlier age of pubertal maturation in females is associated with increased risk for mental health problems in adolescence, compared with on-time or later maturation. However, most investigations of pubertal timing and mental health consider risk for individual disorders and fail to account for comorbidity. A latent-modeling approach using a large, nationally representative sample could better explain the transdiagnostic nature of the consequences of early-onset puberty. METHODS: Data on age of menarche and mental disorders were drawn from a population-representative sample of adolescents (n=4925), ages 13-17...

BACKGROUND: Animal studies suggest that bisphenol A (BPA) may perturb pubertal development in females. However, evidence from human studies is limited. METHODS: This was a cross-sectional study to investigate the association between BPA exposure and pubertal development in school-aged girls. A total of 655 girls aged 9-18 years were selected from three schools in Shanghai, from May to June 2011. We collected one single spot urine sample from each girl. Urine BPA concentrations were measured by modified high-performance liquid chromatography and categorized according to LOD and the median of those above LOD...

Though still a topic of debate, the position that skeletal health is compromised with obesity has received support in the pediatric and adult literature. The limited data relating specifically to trabecular bone microarchitecture, however, have been relatively inconsistent. The aim of this pilot cross-sectional case-control study was to compare trabecular bone microarchitecture between obese (OB) and normal-weight (NW) late-adolescent females. A secondary aim was to compare diaphyseal cortical bone outcomes between these two groups...

REVIEW
Genevieve Victoria Dall, Kara Louise Britt
A woman has an increased risk of breast cancer if her lifelong estrogen exposure is increased due to an early menarche, a late menopause, and/or an absence of childbearing. For decades, it was presumed that the number of years of exposure drove the increased risk, however, recent epidemiological data have shown that early life exposure (young menarche) has a more significant effect on cancer risk than late menopause. Thus, rather than the overall exposure it seems that the timing of hormone exposure plays a major role in defining breast cancer risk...

BACKGROUND: The prevalence of iron deficiency (ID) among non-pregnant, reproductive-age US women significantly exceeds rates among males. In clinical practice ID screening relies on hemoglobin, a late-stage indicator of ID. As a single, low-cost laboratory test to diagnose ID before anemia develops is lacking, the study objective was to improve ID screening by identifying risk factors among non-anemic, iron-deficient reproductive age women. METHODS: Cross-sectional data were from the National Health and Nutrition Examination Survey (NHANES) 2003-2010...

BACKGROUND: Age at menarche is a reproductive trait, which is largely influenced by environmental factors. Each population has a set of lifestyle factors that may shift age at menarche in different direction. Populations of Eastern Slavs, particularly Ukrainians, are underrepresented in studies of reproductive health. The objective of the present research was to determine important non-genetic risk factors, which may contribute to menarcheal onset in Eastern Ukrainians. METHODS: In total 620 females aged 17-25 years participated in the cross-sectional survey...

Imperforate hymen - an often missed diagnosis Imperforate hymen is the most common congenital malformation in the female reproduction system that give rise to obstructive symptoms. If the diagnosis is not made in the newborn girl, symptoms often first arise at menarche. The diagnosis is easy to make but has to be suspected. This case reports describes the typical clinical picture of a late diagnosed imperforate hymen. As shown in this case and from a review of the literature, these girls often have symptoms for a long time before the diagnosis is made...
