Multiple births in Czechia and international perspective Abstract The bachelor thesis deals with the development of multiple births between 1950 and 2019 in the Czech Republic and compares it with the development of multiple births in selected foreign countries, which are France, Japan, Germany, Greece and Sweden. The aim of the bachelor thesis is to analyse the probable causes of the changes in the frequency of multiple births, which has been increasing worldwide especially in the last decades. The bachelor thesis examines the basic characteristics of multiple births and at the same time presents the factors that influence the frequency of multiple births and also looks at the risks associated with multiple births. Keywords: multiple births, multiples, twins, triplets, maternal age, assisted reproduction, trend

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...

Dlouhá, Karolína ; Nývlt, Ondřej (advisor) ; Fabiánová, Jana (referee)
The main goal of this thesis is the analysis of multiple-births in Czech Republic between the years of 1950 and 2005 including the international comparison and assess of the influence of assisted reproduction on occurrence of multiple-births. The thesis is divided into five different parts. The first part is dedicated to the analysis of fertility according to a succession of births in Czech Republic while using the indicators of total fertility, the average age of mothers in the time of childbirth and the total number of new-born babies. The second part focuses on multiple-births considering both historical and contemporary point of view and on possible risks for both the mother and the foetus. Next part describes the assisted reproduction, its history, present and commonly used methods. The fourth part is dedicated to the influence of assisted reproduction on the occurrence of multiple-births and to the analysis of multiple-births with the use of absolute and relative number of mono-births and multiple-births indicators, indicators of total fertility, masculinity index, the rate of stillborn babies and the proportion of children born outside of marriage. The last part compares the development of multiple-births within the European countries according to NIDI 1999 classification.
