    • Hormone references for ultrasound breast staging and endocrine profiling to detect female onset of puberty 

      Madsen, Andre; Bruserud, Ingvild Særvold; Bertelsen, Bjørn-Erik; Roelants, Mathieu; Oehme, Ninnie; Viste, Kristin; Bjerknes, Robert; Almås, Bjørg; Rosendahl, Karen; Mellgren, Gunnar; Sagen, Jørn V.; Juliusson, Petur Benedikt (Journal article; Peer reviewed, 2020)
      Context Application of ultrasound (US) to evaluate attainment and morphology of glandular tissue provides a new rationale for evaluating onset and progression of female puberty, but currently no hormone references complement ...

    • Low BMI, but not high BMI, influences the timing of puberty in boys 

      Oehme, Ninnie Helen Bakken; Roelants, Mathieu; Bruserud, Ingvild Særvold; Madsen, Andre; Bjerknes, Robert; Rosendahl, Karen; Juliusson, Pétur Benedikt (Journal article; Peer reviewed, 2021)
      Background Previous studies investigating the association between weight status and onset of puberty in boys have been equivocal. It is currently unclear to what extent weight class influences puberty onset and ...

    • Perceived barriers in family-based behavioural treatment of paediatric obesity – Results from the FABO study 

      Skjåkødegård, Hanna Flækøy; Hystad, Sigurd William; Bruserud, Ingvild Særvold; Conlon, Rachel P. K.; Wilfley, Denise; Frisk, Bente; Roelants, Mathieu; Juliusson, Pétur Benedikt; Danielsen, Yngvild Sørebø (Journal article; Peer reviewed, 2023)
      Background: To date, few studies have investigated perceived barriers among those who participate in and drop out of family-based behavioural treatment (FBT) for paediatric obesity. Examining experienced barriers during ...

    • Pubertal development in Norwegian girls 

      Bruserud, Ingvild Særvold (Doctoral thesis, 2020-10-23)
      Background: Evidence suggests that girls worldwide are experiencing a decrease in age at pubertal onset, but data from Norwegian girls have not been available. Early pubertal timing is associated with adverse health ...

    • Reference curves for pediatric endocrinology: leveraging biomarker z-scores for clinical classifications 

      Madsen, Andre; Almås, Bjørg; Bruserud, Ingvild Særvold; Oehme, Ninnie Helen Bakken; Nielsen, Christopher Sivert; Roelants, Mathieu; Hundhausen, Thomas Eckhard; Ljubicic, Marie Lindhardt; Bjerknes, Robert; Mellgren, Gunnar; Sagen, Jørn V.; Juliusson, Pétur Benedikt; Viste, Kristin (Journal article; Peer reviewed, 2022)
      Context Hormone reference intervals in pediatric endocrinology are traditionally partitioned by age and lack the framework for benchmarking individual blood test results as normalized z-scores and plotting sequential ...

    • Reference data for testicular volume measured with ultrasound and pubic hair in Norwegian boys are comparable with Northern European populations 

      Oehme, Ninnie; Roelants, Mathieu; Bruserud, Ingvild Særvold; Madsen, Andre; Eide, Geir Egil; Bjerknes, Robert; Rosendahl, Karen; Juliusson, Petur Benedikt (Peer reviewed; Journal article, 2020)
      Aim: To estimate references for testicular volume measured with ultrasound and Tanner stages of pubic hair in Norwegian boys, and to compare the timing of puberty with data from similar populations. Methods: Testicular ...

    • References for ultrasound staging of breast maturation, tanner breast staging, pubic hair, and menarche in Norwegian girls 

      Bruserud, Ingvild Særvold; Roelants, Mathieu; Oehme, Ninnie; Madsen, Andre; Eide, Geir Egil; Bjerknes, Robert; Rosendahl, Karen; Juliusson, Petur Benedikt (Journal article; Peer reviewed, 2020)
      Context: Discriminating adipose and glandular tissue is challenging when clinically assessing breast development. Ultrasound facilitates staging of pubertal breast maturation (US B), but has not been systematically compared ...

    • Testicular ultrasound to stratify hormone references in a cross-sectional Norwegian study of male puberty 

      Madsen, Andre; Oehme, Ninnie; Roelants, Mathieu; Bruserud, Ingvild Særvold; Eide, Geir Egil; Viste, Kristin; Bjerknes, Robert; Almås, Bjørg; Rosendahl, Karen; Sagen, Jørn V.; Mellgren, Gunnar; Juliusson, Petur Benedikt (Peer reviewed; Journal article, 2020)
      Context: Testicular growth represents the best clinical variable to evaluate male puberty, but current pediatric hormone references are based on chronological age and subjective assessments of discrete puberty development ...

    • Timing of menarche in Norwegian girls: Associations with body mass index, waist circumference and skinfold thickness 

      Bratke, Heiko; Bruserud, Ingvild Særvold; Brannsether-Ellingsen, Bente; Assmus, Jörg; Bjerknes, Robert; Roelants, Mathieu; Juliusson, Petur Benedikt (Peer reviewed; Journal article, 2017-06-06)
      Background: Research studies show conflicting results regarding the association between menarche and body weight. The purpose of the present study was to investigate if anthropometric indicators of body composition, body ...
