Zetová, Eva-Marie ; Šťastná, Anna (advisor) ; Waldaufová, Eva (referee)
Fertility of women aged 35 and over in selected European countries ABSTRACT This bachelor's thesis deals with the issue of fertility postponement in Europe. It focuses on the fertility of woman aged 35 and over of age in the Czech Republic, the Netherlands, Spain and Norway between 2010 and 2020. It describes the postponement of fertility in a historical context, influencing factors, risks associated with women's fertility at the age of 35+, childlessness, and fertility differentiation by age. The method of analysis is fertility demographic analysis from a transversal perspective. The thesis examines fertility trends of women aged 35 and over, as well as the current similarities and differences in the fertility of older women in the studied countries. Data analysis showed that in all studied countries and years, the proportion of the fertility intensity of women aged 35 and over to the total fertility rate is increasing. Keywords: fertility, fertility postponement, late motherhood, demographic analysis

Assisted reproduction in Czechia: sociodemographic context of selected treatment methods
Waldaufová, Eva ; Šťastná, Anna (advisor) ; Fait, Tomáš (referee)
Assisted reproduction in Czechia: sociodemographic context of selected treatment methods Abstract In the context of reproductive ageing, which is one of the most important trends observed since the 1990s in Czechia, there is an increase in the use of assisted reproduction technologies (ART). This brings a number of aspects that can be the subject to a study in the field of demography. Mothers who have conceived by ART and mothers who have conceived without ART are different in terms of structure, and mothers with ART have the worse birth outcomes. The aim of the thesis is to analyze the use of ART methods in Czechia and to identify differences/similarities of mothers according to the way of conception. Not only to compare mothers with or without ART, but also the method of ART (in vitro fertilization, frozen embryo transfer, and oocyte reception). Three birth outcomes are analysed in more detail, and they are low birth weight, preterm births, and caesarean section births. The research is based on individualized anonymized data on mothers who gave birth in Czechia between 2013 and 2018. It turns out that there are differences in the structure of mothers according to the way of conception from the view of sociodemographic structure, health condition, and selected birth outcomes. Using the logistic regression...

Fertility postponement in the Czech Republic and selected European countries in the period 1990−2015
Tovarová, Lenka ; Kurtinová, Olga (advisor) ; Šťastná, Anna (referee)
Fertility postponement in the Czech republic and selected European countries in the period 1990−2015 Abstract We have been able to observe the trend of shifting of maternity to later periods of life in European countries since the second half of the 20th century. However crucial for this thesis is to determine whether there have been disparity in delaying of maternity between selected Eastern European (Czech Republic, Slovakia, Poland) and Western European (Germany and Austria) countries since 1990 till present. The goal of this work is to find the relationship among setting of family policies, fertility rate of older women and respondents' views. In the first part of this thesis are outlined basic theories explaining postponing of maternity. There are also listed consequences related to the late maternity. The thesis touches a topic of family policies which influence the phenomenon of late maternity. It presents several fundamental tools of family policies and compares them among selected countries. The second part focuses on a description of demographic indicators that demonstrate the shift in timing of maternity. The main analysis in this thesis is a logistic regression, which explains respondent's views on issues related to a harmonization of family and employment by selected explanatory variables from...

Assisted reproduction - influence on fertility and selected characteristics of newborns in Czechia
Martínková, Kateřina ; Šťastná, Anna (advisor) ; Kocourková, Jiřina (referee)
Assisted reproduction - influence on fertility and selected characteristics of newborns in Czechia Abstract The use of assisted reproductive technology (ART) has become very widespread in recent years, even in Czechia. The aim of this paper is to identify ART's influence on fertility rates and selected characteristics of newborns, especially in the context of demographics in Czechia. The first part of the thesis focuses on describing the process of fertility postponement and the related use of various ART methods. The second part deals with analyzing fertility level and timing and selected characteristics of newborns with emphasis on the comparison of children according to the method of conception. A data set is used for analysis, which was created by linking data on ART cycles from the National Register of Assisted Reproduction with data of children born collected by the Czech Statistical Office. A detailed analysis shows that the spread of assisted reproduction has a significant impact on the overall demographic situation in Czechia, especially in the ability of older women to realize their fertility. This analysis also suggests some differences between infants born via ART versus infants born without the use of ART in terms of birth outcomes. Binary logistic regression also confirms a certain effect of...

Reproductive ageing and multiple births
Kováříková, Eva ; Kocourková, Jiřina (advisor) ; Fait, Tomáš (referee)
Reproductive ageing and multiple births Abstract This diploma thesis is focused on the occurrence of double births in connection with the issue of postponing the fertility of women into old age. The aim of the work is to evaluate the influence of the increasing age of mothers at the birth of a child and the development of methods of assisted reproduction on the increase in the proportion of multiple births in the Czech Republic. Furthermore, to find out the differences or similarities between children born from single and multiple pregnancies in terms of socio-demographic characteristics of mothers. Based on publicly available data from the CZSO, the development of fertility was outlined, as well as the development of multiple births in the years 1950-2019. The extent to which maternal age contributes to the incidence of double pregnancies and the extent to which it is affected by the use of assisted reproduction methods was estimated using the method of direct standardization. Based on anonymized individual data from the NRROD in 2018, the chances of a double birth were estimated using the binary logistic regression method, depending on the age of the mothers and other characteristics. Multiple pregnancies are the greatest risk of assisted reproduction and can cause serious health complications, especially...

Reproductive ageing and its reflection in obstetrics in Czechia
Waldaufová, Eva ; Šťastná, Anna (advisor) ; Kocourková, Jiřina (referee)
Reproductive ageing and its reflection in obstetrics in Czechia Abstract The aim of this thesis is to explore trends in obstetrics in Czechia in the context of increasing maternal age. The key issue is the rise in the percentage of births performed by caesarean section. The first part of the work sums up the current knowledge of fertility development and describes the selected effects of fertility postponement, health risks, especially of caesarean sections. Subsequently, the evolution of fertility in Czechia between 1989 and 2018 and the development in the proportion of births by caesarean section from 1994 to 2018 are analysed. The incidence of caesarean section births is examined based on individual anonymous data from the National Health Information System in 2018. It considers the age of the mothers and other characteristics of the mothers and newborns in Czechia. The odds of giving birth by caesarean section are estimated using the binary logistical regression method. It turns out that in recent years the growth of births executed by caesarean section has stopped, although the age of mothers and the use of assisted reproduction methods continues to grow. Reproductive ageing is reflected in the increase in caesarean section births, but at the same time its occurrence is influenced by a number of other...
