OBJECTIVE To evaluate the correlation between neck circumference and insulin resistance and components of metabolic syndrome in adolescents with different adiposity levels and pubertal stages, as well as to determine the usefulness of neck circumference to predict insulin resistance in adolescents. METHODS Cross-sectional study with 388 adolescents of both genders from ten to 19 years old. Th...
BACKGROUND Treatment effects of removable functional appliances in Class II malocclusion patients according to the pre-pubertal or pubertal growth phase has yet to be clarified. OBJECTIVES To assess and compare skeletal and dentoalveolar effects of removable functional appliances in Class II malocclusion treatment between pre-pubertal and pubertal patients. SEARCH METHODS Literature survey ...
BACKGROUND Previous research suggests that genetic influences on disordered eating may be greater in pubertal than pre-pubertal girls. Although these findings are consistent with pubertal activation of genetic influences on disordered eating, earlier studies were unable to directly test this hypothesis. The purpose of the present study therefore was to directly examine this possibility by inves...
BACKGROUND An estimated 11% of births occur preterm, and survival is improving. Early studies suggested an association between preterm birth and earlier puberty. Given the adverse outcomes associated with early puberty this could have significant public health implications. The objective of this review was to assess the timing of puberty after preterm birth. METHODS Pubmed, Embase, Popline, G...
Little is known about genes regulating male puberty. Further, while many identified pubertal timing variants associate with age at menarche, a late manifestation of puberty, and body mass, little is known about these variants' relationship to pubertal initiation or tempo. To address these questions, we performed genome-wide association meta-analysis in over 11 000 European samples with data on ...
Background and purpose: Stressful events in early-life induce metabolic disorders in adolescence. The aim of this study was to investigate the effect of early-life stress on number or area of Langerhans islets in exposure to foot-shock and psychological stress in male rats. Materials and methods: The rats were divided into six groups: control (without stress), early-stress (stress at 2 weeks o...
An aim of this paper was to discover whether athletes of different pubertal status, chronological age, and gender reported distinct coping strategies in response to stress during a competitive event in their sport. A secondary aim was to examine pubertal status group, chronological age, and gender differences in coping effectiveness. Participants were adolescent athletes (n = 527), classified a...
Background This study tested links between pubertal development and screen time among South Korean adolescent boys and girls. Methods Secondary analysis was conducted on data from the Korean Children and Youth Panel Study (KCYPS) involving 2071 adolescents (age M = 13.14 years). Body mass index (BMI) at Grade 8 (baseline), self-esteem and depression at Grade 9 were examined as mediators of th...
INTRODUCTION Pubertal growth pattern differs according to age at pubertal growth spurt onset which occurs over a five years period (girls: 8-13 years, boys: 10-15 years). The need for more than one pubertal reference pattern has been proposed. We aimed to obtain five 1-year-age-interval pubertal patterns. SUBJECTS AND METHODS Longitudinal (6 years of age-adult height) growth study of 1,453 he...
BACKGROUND Measurement of testicular artery blood flow is used in several species to evaluate reproductive function and testicular and scrotal pathology. In dogs there are inconsistent reports about normal flow in post-pubertal dogs and no information concerning pre-pubertal dogs. The aim of this study was to describe regional differences in testicular artery blood flow in clinically normal pos...
