Objective. To evaluate changes in anthropometric and biochemical parameters in pregnancy and their dynamics during last two decades and to determine the association between anthropometric and biochemical parameters, their influence on fetal and neonatal development. Material and methods. In 1985–2005, anthropometric (height, body mass, weight gain during pregnancy, pelvic measurements, skinfold thicknesses, passive body mass) and biochemical (cholesterol, triglyceride, protein, and iron levels) parameters, their correlation, changes in pregnancy were examined; also the correlations between these parameters and neonatal body mass indices were evaluated. In 1986–1987, 383 pregnant women were examined, in 1998 – 130, and in 2003–2005 – 133. Results. During 20 years, the height of examined women increased on an average of 2.5 cm; they became thinner; body mass index decreased. The body composition became similar to “cylinder” shape due to decreased thickness of adipose tissue in the limbs. The dimensions of bony pelvis – external conjugate and bicristal diameters – decreased. Primiparous women became older (1995 – 22.5 years of age, 2004 – 27.6). At the beginning of investigation, the weight gain was on an average of 21.9% of body mass before pregnancy (13.3 kg) and at the end – 23.9% (14.2 kg). The values of anthropometric parameters vary in a consistent pattern during pregnancy: the lower body mass and body mass index at the beginning of pregnancy, the higher weight gain at the end of pregnancy. Blood serum levels of cholesterol, triglycerides, and especially iron were decreased during the study. Conclusions. An inverse correlation between body mass index and lipid metabolism in pregnancy was revealed: the higher body mass index was at the beginning of pregnancy, the lower increase in lipid concentration was during pregnancy. At the beginning of investigation as well as after 20 years, women with low body mass index showed...

Epidemiologiniais tyrimais nustatytos androgenų sąsajos su įvairiais metaboliniais veiksniais bei širdies ir kraujagyslių ligų rizika paskatino susidomėjimą naujais vyrų reprodukcinės sveikatos aspektais. Iki šiol Lietuvoje nebuvo nustatytos normalios vyrų androgenų koncen¬tracijos ribos, nebuvo atlikta reprodukcinės sveikatos, antropometrinių ir metabolinių rodiklių sąsajų analizės tyrimų. Pasaulyje iki šiol trūksta nuoseklios informacijos apie metabolinių ir antropometrinių rodiklių ryšius su lytiniais hormonais, ypač homogeniškose tiriamųjų imtyse. Trūksta informacijos apie androgenų sąsajas su pažintinėmis funkcijomis, emocine būkle ir gyvenimo kokybės vertinimu. Daugelis tyrimų, kuriais vertintas pakaitinio gydymo testosteronu efektyvumas – trumpalaikiai, juose dau¬giausiai dėmesio skirta struktūriniams, o ne funkciniams rodikliams. Šiuo tyrimu siekta aprašyti jaunų bei vidutinio amžiaus vyrų reprodukcinės sveikatos sąsajas su antro¬pometrijos, metabolinės bei psichologinės būklės rodikliais. Tai iki šiol didžiausia savo apimtimi Lietuvos vyrų androgenų sąsajų analizė. Šiuo darbu siekiama sistemingai atsakyti į iškeltus aktualius klau¬simus, nustatyti normalios ir optimalios androgenų koncentracijos ribas, homogeniškose amžiumi tiriamųjų grupėse įvertinti šių hormonų koncen¬tracijos grupių sąsajas su kūno sudėties ir medžiagų apykaitos rodikliais bei nustatyti, kokius sergančiųjų androgenų nepakankamumu funkcinius pokyčius sąlygoja ilgalaikis optimalus pakaitinis... [toliau žr. visą tekstą] Associations between androgens and various metabolic factors, as well as cardiovascular morbidity shown in recent epidemiological studies sparked interest in new aspects of male reproductive health. Reference values for normal androgen levels in Lithuanian population have not yet been established and no relationship studies on reproductive health and anthropometric, as well as metabolic parameters have been performed. Unequivocal information on associations among the aforementioned factors is lacking globally, especially those performed in homogenous populations. More information on androgen associations with cognitive function, emotional state and evaluation of quality of life is required. Most of the studies on effectiveness of testosterone replacement therapy were of short duration and mostly focused on structural, rather than functional parameters. The purpose of the study was to describe associations between reproductive health and anthropometric, metabolic, as well as psychological parameters in young and middle-aged men. This is the largest androgen association analysis in Lithuanian population. This work seeks for systematic responses to questions of interest: to establish reference values for normal and optimal androgen levels, to evaluate their relationship with anthropometric and metabolic factors in populations that are homogenous by age, and to assess the functional changes that long-term optimal testosterone replacement therapy may induce in patients with...
