BACKGROUND To evaluate the neonatal outcome and the prevalence of congenital malformations in children born after IVF in northern Finland we carried out a population-based study with matched controls. METHODS Firstly, 304 IVF children born in 1990-1995 were compared with 569 controls, representing the general population in proportion of multiple births,(More)
In 1993, in Finland at least 0.7% of all pregnancies ending in birth were assisted by in-vitro fertilization (IVF). The purpose of this study was to compare IVF mothers with other mothers, and the perinatal health and health care costs of IVF infants to those of other infants. The main source of information was the Medical Birth Register for 1991-1993 (n =(More)
OBJECTIVE To study the occurrence of major congenital anomalies (CAs) among children born after IVF (IVF, microinjections, and frozen embryo transfers) and after ovulation inductions with or without insemination (other assisted reproductive technologies [ART]). DESIGN Register-based study. SETTING Data regarding CAs were obtained from the Register of(More)
OBJECTIVE The purpose of this study was to use nationwide registries to examine the health of children up to 4 years of age who were born as a result of in vitro fertilization. METHODS Children born after in vitro fertilization (N = 4559) from 1996 to 1999 were monitored until 2003. Two control groups were selected from the Finnish Medical Birth Register(More)
OBJECTIVE To determine rates of suicide associated with pregnancy by the type of pregnancy. DESIGN Register linkage study. Information on suicides in women of reproductive age was linked with the Finnish birth, abortion, and hospital discharge registers to find out how many women who committed suicide had had a completed pregnancy during her last year of(More)
BACKGROUND The frequency and importance of complications of IVF and other ovulation induction (OI) are poorly known. We examined the occurrence of serious complications and miscarriages leading to hospitalization or operation after IVF (including microinjections and frozen embryo transfers) and OI treatment (with or without insemination). METHODS Women(More)
With serum screening (MS-AFP and hCG testing for Down's syndrome) women have to make several decisions in a limited time: whether to participate in the screening in the first place; then, if increased risk for fetal abnormality is detected, whether to have a diagnostic test, and finally, what to do if fetal abnormality is detected. The aim of this study was(More)
STUDY OBJECTIVE Several studies on differences in infant outcome by socioeconomic position have been done, but these have usually been based on ad hoc data linkages. The aim of this paper was to investigate whether socioeconomic differences in perinatal health in Finland could be regularly monitored using routinely collected data from one single register.(More)
BACKGROUND The purpose of this study was to investigate whether perinatal health outcomes changed during the 1990s with the increasing use of IVF. METHODS Data were from the Finnish Medical Birth Register for periods 1991-1993 and 1998-1999. Outcomes of IVF infants and other infants were compared, both overall and separately for singleton and multiple(More)
BACKGROUND Results of earlier studies on cancer risk in infertile women are inconsistent for many cancer types. Our goal was to study cancer incidence among a cohort of women treated with IVF, including ICSI and frozen embryo transfer (FET), compared with that of a control population. METHODS A cohort of women who purchased drugs for IVF (including ICSI(More)
