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

   Författare :Petra Otterblad Olausson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :maternal age; pregnancy in adolescence; pregnancy outcome; infant mortality; infant; premature; risk factors; socioeconomic factors; educational status; single parent; twins; cause of death;

   Sammanfattning : 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. LÄS MER

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

   Författare :Emma Nilsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Adverse pregnancy outcomes; pre-eclampsia; gestational hypertension; fetal growth restriction; low birth weight; infant death; schizophrenia; genetic and environmental components; epidemiology; twins; families;

   Sammanfattning : 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. LÄS MER

4. 3. Gender differences in perinatal morbidity and long term consequences of preterm birth

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; morbidity; neonatal; gender; IL-1ra; salivary cortisol; blood pressure; circulatory; mortality; obstetrical complications; ventilatory twins;

   Sammanfattning : Newborn male infants have higher morbidity and mortality than female infants. Male fetal gender is associated with an overall increased risk of preterm birth and complications related to pregnancy are overrepresented in women carrying male fetuses. LÄS MER

5. 4. Does cancer originate in utero?

   Författare :Magnus Kaijser; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Epidemiology; prenatal exposure delayed effects; breast neoplasms; testicular neoplasms; lung neoplasms; pregnancy; estrogens; estriol; low birth weight body weight; height; twins; matemal exposure; smoking; infant premature; small for gestational age.;

   Sammanfattning : The purpose of the present thesis was to evaluate Trichopoulos' hypothesis that breast cancer can originate in utero, and to examine the role of antenatal estrogen exposure in the etiology of testicular cancer. First, we used data from a Swedish-Norwegian cohort study on risk factors for small-for-gestational-age births to identify markers for antenatal estrogen exposure. LÄS MER

7. 5. Prenatal influences on health outcomes over the lifespan : effects of smoking, socio-economic status and foetal growth

   Författare :Lovisa Högberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The most remarkable development during a person‟s life takes place in utero. Through about 280 days of proliferation and differentiation one single cell is developed into a human being. As this is the time when the whole body is formed, it is easy to imagine that exposures during this time can have health consequences over the lifespan. LÄS MER
