To address questions about sex assignment in children with ambiguous genitalia, we studied gender identity in girls with congenital adrenal hyperplasia (CAH) in relation to characteristics of the disease and treatment, particularly genital appearance and surgery. A 9-item gender identity interview was administered to 43 girls with classical CAH ranging in age from 3-18 yr, 7 tomboys, and 29 sis...

In this study, we examined oxidative stress after a swimming session, the responses of the antioxidant defences, and the influence of gender on these responses. Fifteen boys and eight girls participated voluntarily in the study. Plasma concentrations of 17-beta-estradiol, vitamin E, retinol, carotenes, ascorbate, malondialdehyde, and the carbonyl index were determined. Creatine kinase, gamma gl...

This research analyzed the iron status, clinical symptoms and physical characteristics between normal and anemic group of middle school girls in the Ulsan metropolitan area. It was carried out with 237 subjects (normal 190, anemic subject 47). They were evaluated with a questionnaire and measurement of hematological indices. BMI (kg/m(2)) of the two groups were 19.54 +/- 2.44 (normal girls) and...

The aim of this study was to examine executive function (EF) skills in girls with fragile X or Turner syndrome, using the Contingency Naming Test (CNT). The CNT is a Stroop-like task involving a 1- or 2-attribute contingency rule. We predicted that girls with fragile X would make errors reflecting poor cognitive flexibility and working memory limitations. We predicted that girls with Turner syn...

In many low-income countries, girls marry early and have children very soon after marriage. Although conveying infant and young child nutrition (IYCN) knowledge to adolescent girls in time is important to ensure the well-being of their children, little is known about the best ways to convey these messages. This study examines the extent of, and sources from which adolescent girls derive IYCN kn...

OBJECTIVE To determine the etiologies and clinical characteristics of children presenting with PP. SUBJECTS AND METHOD The medical records of 307 children (292 girls, 15 boys) with PP (1995-2009) were reviewed. RES...

Menarche, the onset of menstruation is a fundamental part of a girl's transition from childhood to adolescence. Studies show that girls in many countries experience menarche with insufficient information and support. Girls from around the world report feeling ashamed and afraid. The potential health effects of such experiences include a weakening of girls' sense of self-confidence and competenc...

Children ages 6, 8, and 10 years were given tasks designed to assess their beliefs about risk of injury from activities. Children were asked to appraise the risk of injury for boys and girls engaging in various play behaviors and to judge the sex of the character in stories about children engaging in activities that result in injuries. Results revealed gender biases in children's appraisals of ...

people's, particularly girls', images of scientists, technologists, engineers and mathematicians (STEM) are constructed. Studies have examined how children's views of science and scientists develop as they grow up and why girls' (and boys') participation in school science declines with age. Key factors include a decline in many girls' self-belief in their abilities in science, particularly the ...

The aim of this paper is to understand how peers can influence adolescent girls’ dieting behaviour and their body image. Departing from imitation and social learning theories, we study whether adolescent girls tend to model their peer group dieting behaviours, thus influencing their body image construction. Our study was conducted through an enquiry applied to a cluster sample of 466 adolescent...
