Obesity before pregnancy is associated with an increased risk of several adverse outcomes pregnancy. The profiles among lean, normal, or mildly overweight women are not, however, well established.
A quality control study was made of the Swedish Medical Birth Registry. This registry used one mode data collection during 1973-1981 and another from 1982 onwards. The number errors in register checked by comparing information with a sample original medical records, variability use diagnoses between hospitals studied. Different types were identified quantified efficiency two methods evaluated.
Preterm birth is a leading cause of infant mortality, morbidity, and long-term disability, these risks increase with decreasing gestational age. Obesity increases the risk preterm delivery, but associations between overweight obesity subtypes delivery are not clear.To study early pregnancy body mass index (BMI) by age precursors delivery.Population-based cohort women live singleton births in Sweden from 1992 through 2010. Maternal characteristics were obtained nationwide Swedish Medical...
Background. Etiologic hypotheses in infantile autism suggest a strong genetic component, as well possible environmental risks linked to early fetal development. We evaluated the association of maternal, pregnancy, delivery, and infant characteristics risk autism. Methods. conducted case-control study nested within population-based cohort (all Swedish children born 1974–1993). used prospectively recorded data from Birth Register, which were individually Inpatient Register. Cases 408 (321 boys...
<b>Objective</b> To investigate whether pre-eclampsia is more common in first pregnancies solely because fewer affected women, who presumably have a higher risk of recurrence, go on to subsequent pregnancies. <b>Design</b> Prospective cohort study. <b>Setting</b> Swedish Medical Birth Register. <b>Participants</b> 763 795 primiparous mothers had their births Sweden, 1987-2004. <b>Main outcome measures</b> Pre-eclampsia. <b>Results</b> The was 4.1% the pregnancy and 1.7% later overall....
Maternal obesity is associated with increased risks of gestational diabetes, large-for-gestational-age infants, preterm birth, congenital malformations, and stillbirth. The these outcomes among women who have undergone bariatric surgery are unclear.We identified 627,693 singleton pregnancies in the Swedish Medical Birth Register from 2006 through 2011, which 670 occurred had previously for whom presurgery weight was documented. For each pregnancy after surgery, up to five control were...
Objective To determine whether customised birthweight standard improves the definition of small for gestational age and its association with adverse pregnancy outcomes such as stillbirth, neonatal death, or low Apgar score. Design Population based cohort study. Births in Sweden between 1992‐95 ( n =326,377). Methods Risks score under four at five minutes were calculated lowest 10% birthweights according to population‐based standards, compared data from group over this limit. attributable...
<h3>Context</h3>Preterm birth, intrauterine growth restriction, and delivery-related hypoxia have been associated with schizophrenia. It is unclear whether these associations pertain to other adult-onset psychiatric disorders perinatal events are independent.<h3>Objective</h3>To investigate the relationships among gestational age, nonoptimal fetal growth, Apgar score, various in young adult life.<h3>Design</h3>Historical population-based cohort study.<h3>Setting</h3>Identification of...
The objective of this study was to evaluate and compare risk factor patterns in association with preeclampsia gestational hypertension. data were collected from Swedish Medical Birth Register include all nulliparas aged 34 years or less who gave birth at the University Hospital Uppsala, Sweden, during 1987–1993. Of these 10,666 women, 4.4% developed hypertension, 5.2% preeclampsia. following factors significantly associated increased preeclampsia: type 1 diabetes (odds ratio = 5.58, 95%...
The Swedish Twin Registry was first established in the late 1950s. Today it includes more than 170,000 twins — principle all born Sweden since 1886. In this article we describe some ongoing and recently completed projects based on registry. particular, recent efforts to screen between 1959 1985, young twin pairs when they turn 9 12 years of age. For these studies, present initial frequencies common conditions exposures.
Background Postpartum depression (PPD) can result in negative personal and child developmental outcomes. Only a few large population-based studies of PPD have used clinical diagnoses no study has examined how maternal history interacts with known risk factors. The objective this was to examine the impact on pre- perinatal Methods A nationwide prospective cohort all women live singleton births Sweden from 1997 through 2008 conducted. Relative (RR) within first year postpartum two-sided 95%...

The Swedish Twin Registry (STR) today contains more than 194,000 twins and 75,000 pairs have zygosity determined by an intra-pair similarity algorithm, DNA, or being of opposite sex. Of these, approximately 20,000, 25,000, 30,000 are monozygotic, same-sex dizygotic, opposite-sex dizygotic pairs, respectively. Since its establishment in the late 1950s, STR has been important epidemiological resource for study genetic environmental influences on a multitude traits, behaviors, diseases....
