Anthropometric characteristics and pulsatile growth hormone secretion patterns in premenopausal and postmenopausal women from Austria.
The intercorrelations between 18 anthropometric variables, describing amount and distribution of subcutaneous fat tissue, and 12 growth hormone (GH) levels which had been obtained at intervals of 2 hours over a period of 24 hours, were tested in 25 premenopausal and 23 postmenopausal women from Austria. The 12 GH levels were included in the analyses because the GH shows typical pulsatile secretion patterns with peak values about midnight. Initially, premenopausal and postmenopausal women showed significantly different secretion patterns of GH; furthermore it became evident that the GH constantly correlated positively, however insignificantly, with stature height, but significantly negatively with all those measures describing amount and distribution of subcutaneous fat tissue. Beyond that the present paper indicates that age and menopausal status have a marked influence on GH secretion patterns. It became evident that, independent of menopausal status, typical association patterns between frequency of GH pulses per 24 hours, as well as the amplitude of the individual bursts and the amount of subcutaneous fat tissue, occur.
