      BACKGROUND: Congenital anomalies of the kidney and the urinary tract (CAKUTs) are relatively common birth defects. The combined prevalence in Europe was 3.3 per 1000 in 2012. The risk factors for these anomalies are not clearly identified. The aims of our study were to calculate the birth prevalences of urinary malformations in Murmansk County during 2006 to 2011 and to investigate related prenatal ...

    • Epidemiology and new opportunities of investigating risk factors for congenital malformations in Northwest Russia: a registry-based linkage study

      <p>Birth defects constitute an important public health issue as they are the main causes of perinatal and infant mortality. To address incomplete data coverage in Russia, the studies described in this thesis all have a registry-based study design, and were based on the linkage of the Murmansk County Birth Registry (MCBR) and the Murmansk Regional Congenital Defects Registry (MRCDR) to investigate ...

    • Risk Factors for Ventricular Septal Defects in Murmansk County, Russia: A Registry-Based Study 

      Kovalenko, Anton Alexandrovich; Anda, Erik Eik; Odland, Jon Øyvind; Nieboer, Evert; Brenn, Tormod; Krettek, Alexandra (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-24)
      Cardiovascular malformations are one of the most common birth defects among newborns and constitute a leading cause of perinatal and infant mortality. Although some risk factors are recognized, the causes of cardiovascular malformations (CVMs) remain largely unknown. In this study, we aim to identify risk factors for ventricular septal defects (VSDs) in Northwest Russia. The study population ...

      Kovalenko, Anton Alexandrovich; Brenn, Tormod; Odland, Jon Øyvind; Nieboer, Evert; Krettek, Alexandra; Anda, Erik Eik (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-30)
      The objective was to assess the prevalence of selected major birth defects, based on data from two medical registries in Murmansk County, and compare the observed rates with those available for Norway and Arkhangelsk County, Northwest Russia. It included all newborns (≥22 completed weeks of gestation) registered in the Murmansk County Birth Registry (MCBR) and born between 1 January 2006 and 31 ...
