Assisted reproductive technology (ART) is not an independent risk factor for breech presentation among singleton term births in Vienna, Austria
Assisted reproductive technologies (ARTs) such as in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) are still discussed critically, as there is no consensus on whether these treatments could be the cause of risk factors for obstetric problems such as breech presentation. The aim of this study was to test the association between ART and breech presentation among 11920 singleton term births taking place in Vienna from 2010 to…
The Impact of Higher Than Recommended Gestational Weight Gain on Fetal Growth and Perinatal Risk Factors—The IOM Criteria Reconsidered
A too-high gestational weight gain, in combination with steadily increasing obesity rates among women of reproductive age, represents an enormous obstetrical problem, as obesity and high gestational weight gain are associated with enhanced fetal growth, low vital parameters, and increased cesarean section rates. This medical record-based study investigates the association patterns between too-low as well as too-high gestational weight gain, accor…
Fetal size at the 32nd gestational week is associated with the risk of breech presentation at term birth
Fetuses who remain in a breech presentation until term birth (≥37 gestational weeks) differed significantly in head and abdominal dimensions from cephalic fetuses from the 32nd gestational week onwards
Maternal Prepregnancy Obesity Affects Foetal Growth, Birth Outcome, Mode of Delivery, and Miscarriage Rate in Austrian Women
The increasing obesity rates among women of reproductive age create a major obstetrical problem as obesity during pregnancy is associated with many complications, such as a higher rate of caesarean sections. This medical record-based study investigates the effects of maternal prepregnancy obesity on newborn parameters, birth mode, and miscarriage rate. The data of 15,404 singleton births that had taken place between 2009 and 2019 at the public Da…
Pregnancy Outcome during the First Covid 19 Lockdown in Vienna, Austria
The COVID 19 pandemic represents a major stress factor for non-infected pregnant women. Although maternal stress during pregnancy increases the risk of preterm birth and intrauterine growth restriction, an increasing number of studies yielded no negative effects of COVID 19 lockdowns on pregnancy outcome. The present study focused on pregnancy outcome during the first COVID 19 lockdown phase in Austria. In particular, it was hypothesized that the…
Caesarean sections are associated with sonographic determined fetal size from the second trimester onwards
Human birth represents a critical and life-threatening event in the life of mother and child and is therefore of special importance for anthropological as well as public health research

The association patterns between maternal age and foetal growth parameters as well as newborn size were analysed using a dataset of 4737 singleton term births taking place at the Viennese Danube hospital. Foetal growth patterns were reconstructed by the results of three ultrasound examinations carried out at the 11th/12th, 20th/21th and 32th/33thweek of gestation. In detail, crown-rump length, biparietal diameter, fronto-occipital diameter, head …
Recent Lifestyle Parameters Are Associated with Increasing Caesarean Section Rates among Singleton Term Births in Austria
Caesarean section (CS) rates are increasing in many parts of the world, recently reaching about 20% worldwide. The postmodern lifestyle characteristics, obesity and delayed childbirth, have been put forward as the main reasons for high CS rates. The present study tests the association patterns between lifestyle parameters and delivery mode on a data set of 3786 births in Vienna between 2005 and 2013. The focus is exclusively on singleton term bir…
Maternal Height and Pre-Pregnancy Weight Status Are Associated With Fetal Growth Patterns and Newborn Size
The impact of maternal height, pre-pregnancy weight status and gestational weight gain on fetal growth patterns and newborn size was analysed using a dataset of 4261 singleton term births taking place at the Viennese Danube Hospital between 2005 and 2013. Fetal growth patterns were reconstructed from three ultrasound examinations carried out at the 11 th /12 th , 20 th /21 th and 32 th /33 th weeks of gestation. Crown–rump length, biparietal diam…
Determinants of gestational weight gain with special respect to maternal stature height and its consequences for newborn vital parameters
An appropriate gestational weight gain is an essential factor of female reproductive success because gestational weight gain influences newborn size but also maternal and infant morbidity and mortality. This paper aims to analyze the impact of maternal somatic factors, first of all maternal stature height, on gestational weight gain. Additionally the effect of gestational weight gain and other maternal somatic factors on newborn size was tested. …
Nicotine Consumption Before and During Pregnancy Affects Not Only Newborn Size but Also Birth Modus
The associations between cigarette smoking before and during pregnancy and maternal body size (pre-pregnancy weight status, end of pregnancy weight status, weight gain during pregnancy) and newborn size (birth weight, length, head circumference, arcomial circumference), as well as birth modus, were tested in 7803 single full-term births in Vienna. Nicotine consumption before and during pregnancy was found to be associated with smaller and lighter…
Impact of maternal age and maternal somatic characteristics on newborn size
Pregnancies during early adolescence were commonly thought to represent special risks, such as preterm delivery or low‐weight newborns, resulting in increased mortality and morbidity of mother and child. An important biopsychosocial interaction can be assumed. In the present study the impact of maternal age and maternal somatic characteristics such as prepregnancy weight, stature, or pregnancy weight gain on newborn somatometric features (birth w…
Advanced maternal age is not only associated with newborn somatometrics but also with the mode of delivery
Special risks were found for mothers older than 35 years, so the lower rates of ovulatory cycles during this phase of life may be interpreted as an adaptation to increased risks for complications and poor pregnancy outcome
Association between maternal age at menarche and newborn size
The impact of maternal age at menarche on newborn size was tested using data from 4,996 single births taking place at Vienna, Austria, between 1985 and 1995--so-called teenager pregnancies were excluded from the present analyses. All women experienced pregnancies between the ages of 19 to 42 years. Maturational time was related significantly to infant weight and length independent of maternal age and behavioral variables such as smoking. Early ma…
Maternal prepregnancy weight status and pregnancy weight gain as major determinants for newborn weight and size
The impact of maternal anthropometric characteristics, above all prepregnancy weight status and pregnancy weight gain, on newborn size was tested using 10,240 single births in the University Hospital of Vienna, Austria. Highly significant relations between maternal prepregnancy weight status and newborn size were observed. With higher maternal prepregnancy body mass index, higher birthweight, length, head circumference, acromial circumference and…
