  1. 1. Childhood Body Mass Index and Pubertal Timing - Changes over time and associations with adult cardiovascular mortality

    Författare :Maria Bygdell; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childhood BMI; Puberty; BMI change during puberty; Cardiovascular mortality;

    Sammanfattning : Puberty in boys has long been an under-investigated area of research mainly due to the lack of an easily available pubertal marker, corresponding to menarche for girls. Using a unique, large, population-based cohort, this thesis targets some of the knowledge gaps regarding puberty and BMI change during puberty in boys. LÄS MER

  3. 2. Human growth patterns - with focus on pubertal growth and secular changes

    Författare :Anton Holmgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth; height; QEPS model; puberty; growth pattern; BMI; secular change; growth phases infancy childhood puberty ;

    Sammanfattning : Introduction: Human growth is a dynamic process, an indicator of health and disease. Previous used growth models have been limited in describing the pubertal growth spurt. Aim: The overall aim of this thesis is to increase knowledge regarding human growth. LÄS MER

  4. 3. Testosterone and 17beta-oestradiol secretions in children and adolescents. Assay development, levels for comparison and clinical applications

    Författare :Carina Ankarberg-Lindgren; Göteborgs universitet; []
    Nyckelord :17beta-oestradiol; testosterone; sensitive assay; data for comparison; prepuberty; puberty; children; pubertal induction.;

    Sammanfattning : Accurate measurements of 17beta-oestradiol and testosterone are important in clinical settings of pubertal disorders and hormone replacement therapy among children. Most assays for measurement of these steroids are optimised for fertility investigations in adults and are not sensitive enough for quantification in children. LÄS MER

  5. 4. On the developmental significance of female pubertal timing

    Författare :Therése Skoog; Håkan Stattin; Margaret Kerr; Judith Dubas; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; female; puberty; pubertal timing; development; adjustment; longitudinal; sexuality; peer relations; weight status; mechanisms; conditions; Psychology; Psykologi; Psykologi; Psychology;

    Sammanfattning : Puberty is the process of becoming sexually mature and it has fundamental somatic and psychosocial implications. The focus of this dissertation was the short and long term developmental significance, concerning both soma et psyche, of female pubertal timing. Four studies were designed to accomplish these aims.

  7. 5. Growth hormone responsiveness in children : results from Swedish multicenter clinical trials of growth hormone treatment

    Författare :Elena Lundberg; Berit Kriström; Kerstin Albertsson-Wikland; Roland Pfäffle; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gain in height; puberty; IGHD; non-GHD; IGF-I; bioavailability;

    Sammanfattning : The general aims of the thesis were to study GH responsiveness by estimation of pharmacokinetics and bioavailability of injected recombinant human GH (rhGH), of growth response as gain in heightSDS during childhood and puberty, and IGF-I response as change in circulating IGF-ISDS and IGFBP3SDS. Methods Short children were recruited during 1988–1999 into two national randomized multicentre clinical trials on growth until adult height. LÄS MER
