Abstract

Background: Whether children with chromosomal disorders of growth and puberty are affected by secular trends (STs) as observed in the general population remains unanswered, but this question has relevance for expectations of spontaneous development and treatment responses. Objectives: To study STs in birth parameters, growth and pubertal development in girls with Turner syndrome (TS). Study design: Retrospective analysis of KIGS data (Pfizer International Growth Database). We included all TS patients who entered KIGS between 1987 and 2012 and were born 1975 to 2004, who were pre-pubertal and growth-treatment naïve at first entry (total number: 7219). Pre-treatment height and ages at treatment start were compared across 5-year birthyear groups, with sub-group analyses stratified by induced or spontaneous puberty start. Results: We observed significant STs across the birthyear groups for birth weight (+0.18 SDS, p<0.001), pre-treatment height at mean age 8 years (+0.73 SDS, p<0.001), height at start of GH-therapy (+0.38 SDS, p<0.001) and start of puberty (+0.42 SDS, p<0.001). Spontaneous puberty onset increased from 15% to 30% (p<0.001). Mean age at GH treatment start decreased from 10.8 to 7.4 years (-3.4 years; p<0.001), substantial declines were seen in ages at onset of spontaneous and induced puberty (-2.0 years; p<0.001) and menarche (-2.1 years; p<0.001). Conclusion: Environmental changes leading to increased height and earlier, and also more common, spontaneous puberty are applicable in TS as in normal girls. In addition, greater awareness for TS may underlie trends to earlier start of GH therapy and induction of puberty at a more physiological age.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
