  2. 2. Genetic factors affecting pregnancy duration in humans

    University dissertation from Gothenburg : University of Gothenburg

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; genomics; GWAS; Mendelian randomization; causal inference; preterm birth; pregnancy; gestation; height; text mining;

    Abstract : This thesis investigates the mechanisms behind human pregnancy duration. Too short gestation is a direct cause of perinatal, neonatal, and infant mortality. Deviation from normal pregnancy length is also associated with a child's morbidity, even in the adulthood. READ MORE

  4. 4. Teenage childbearing : pregnancy outcomes and long-term consequences for the mothers

    University dissertation from Stockholm : Karolinska Institutet, Department of Medical Epidemiology and Biostatistics

    Author : Petra Otterblad Olausson; Karolinska Institutet.; Karolinska Institutet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; maternal age; pregnancy in adolescence; pregnancy outcome; infant mortality; infant; premature; risk factors; socioeconomic factors; educational status; single parent; twins; cause of death;

    Abstract : The purposes of the thesis were to study effects of low maternal age on adverse pregnancy outcomes, predictors of teenage childbearing, and long-term effects of teenage motherhood on the women's social situation later in life and risk of premature death. The effects of low maternal age at first birth on risks of adverse pregnancy outcomes, primarily preterm birth and infant mortality, were studied in three population-based cohort studies. READ MORE

  5. 5. Genetic epidemiological studies of adverse pregnancy outcomes and the role of schizophrenia

    University dissertation from Stockholm : Karolinska Institutet, Department of Medical Epidemiology and Biostatistics

    Author : Emma Nilsson; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adverse pregnancy outcomes; pre-eclampsia; gestational hypertension; fetal growth restriction; low birth weight; infant death; schizophrenia; genetic and environmental components; epidemiology; twins; families;

    Abstract : The purposes of this thesis were to investigate the importance of genetic and environmental factors in the development of adverse pregnancy outcomes and to investigate the role of schizophrenia as a risk factor for and a consequence of adverse pregnancy outcomes. In the first study we investigated the importance of genetic and environmental factors for pre-eclampsia and gestational hypertension and whether the diseases share genetic etiology. READ MORE
