Abstract

Spontaneous growth hormone secretion rates and secretory patterns were studied in a group of normal prepubertal children, adolescents and young and older adults by determining the concentration of growth hormone in plasma samples obtained at 20-min intervals over a 24-hr period. Prepubertal children secreted growth hormone only during sleep and not while awake and had a mean secretion rate of 91 μg/24 hr (range 54–122 μg/24 hr). Mean duration of secretion was 110 min/24 hr (range 60–180 min/24 hr). Adolescents secreted growth hormone during both awake and sleep periods and had a mean secretion rate of 690 μg/24 hr (range 391–1406 μg/24 hr). Mean duration of secretion was 226 min/24 hr (range 100–300 min/24 hr). Secretion rates in young adults (21–41 yr) averaged 385 μg/24 hr (range 215–769 μg/24 hr). Average duration of secretion was 133 min/24 hr (range 100–300 min/24 hr). Growth hormone was secreted during both awake and asleep periods but the number of secretory episodes was less than in adolescents. In older adults (42–62 yr) the total 24-hr secretion of growth hormone decreased and approached zero in three of five studies. These data clearly demonstrate an age related change in the spontaneous secretory rate and secretory pattern of growth hormone.

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.
