      Background: Mental disorders often have onset early in life, contribute substantially to the global disease burden, and may interfere with young people’s ability to complete age-relevant tasks in important developmental ...
    • Risk of attention‐deficit hyperactivity disorder in offspring of mothers with infections during pregnancy 

      Walle, Kjersti Mæhlum; Askeland, Ragna Bugge; Gustavson, Kristin; Mjaaland, Siri; Ystrøm, Eivind; Lipkin, W. Ian; Magnus, Per Minor; Stoltenberg, Camilla; Susser, Ezra; Bresnahan, Michaeline; Hornig, Mady; Reichborn-Kjennerud, Ted; Ask, Helga (Journal article; Peer reviewed, 2022)
      Background Maternal infections during pregnancy are common events that have been suggested to be risk factors for Attention-deficit hyperactivity disorder (ADHD) in offspring. Only a few studies have been conducted to ...
    • Sensitivity and specificity of early screening for autism 

      Suren, Pål; Havdahl, Alexandra; Bresnahan, Michaeline; Hirtz, Deborah; Hornig, Mady; Lord, Catherine; Reichborn-Kjennerud, Ted; Schjølberg, Synnve; Øyen, Anne-Siri; Magnus, Per; Susser, Ezra; Lipkin, W. Ian; Stoltenberg, Camilla (Peer reviewed; Journal article, 2019)
      Background: Early identification and diagnosis is beneficial for children with autism spectrum disorder (ASD). Universal early screening is recommended by many experts, but disputed because evidence is limited, and sensitivity ...
    • Sleep Duration and Nocturnal Awakenings in Infants Born with Gestational Risk 

      Hysing, Mari; Reichborn-Kjennerud, Ted; Markestad, Trond; Elgen, Irene Bircow; Sivertsen, Børge (Peer reviewed; Journal article, 2019)
      Objective: Infants born with gestation-related risks (low birth weight (LBW), small for gestational age (SGA), and prematurely born infants) are faced with a cascade of developmental issues. The aim of this study was to ...
    • Sleep problems and depressive symptoms in toddlers and 8-year-old children: A longitudinal study 

      Sivertsen, Børge; Harvey, Allison G.; Reichborn-Kjennerud, Ted; Ystrøm, Eivind; Hysing, Mari (Journal article; Peer reviewed, 2021)
      Sleep and depression are interlinked throughout the lifespan, but very few studies have examined the directionality of the sleep–depression link in children. The aim of the current study was to prospectively examine the ...
    • Statistical and functional convergence of common and rare genetic influences on autism at chromosome 16p
