Background and activities
Position: Professor emeritus of paediatrics (Perinatal and paediatric epidemiology)
Main field of research:
Perinatal and paediatric epidemiology.
Since 1985 I have studied various aspects of prematurity and intrauterine growth restriction (IUGR), with emphasis on growth and development. In a Scandinavian multicenter study on causes and consequences of IUGR sponsored by NIH, I studied the consequences of environment and growth patterns in utero and in early infancy for later health and development . I was among the first to report that smoking exposure in utero was a risk factor for overweight in early childhood. Moreover, I am senior member and co-founder of the perinatal injury group Center for early brain development CEBRA (https://www.ntnu.no/ikom/cebra#/view/about).
Around 2002 I founded the Norwegian cerebral palsy (CP) registry (CPRN). The registry is approved as national health quality register. Since 2006, after ending my period as academic dean, my main research has therefore been on CP etiology, clinical picture and co-morbidity, and this activity has had a steep increase, as reflected in the activity of our CP-research group: https://www.ntnu.no/ikom/cp#/view/about
At present, we are conducting a large multicenterstudy on the effects of Botulinum Toxin A- injections ("Botox") on walking in children with CP. The study is a placebo-controlled, double blinded ramdomized trial, involving four Norwegian University Clinics, and one center in Poland, as well as one in France. https://www.ncbi.nlm.nih.gov/pubmed/28166806 .
I have a special interest in educational issues: My main positions since 1986 have been as teacher in paediatrics. I was elected academic dean in 2002-2006. During this period I revised the medical curriculum and conducted educational projects aiming at improving specialist education in paediatrics, anaesthesiology, child- and adolescent psychiatry, general psychiatry and geriatrics. I have also published a couple of papers on medical education. Finally, I have participated in the assessment of Medical Schools in Sweden, and the medical curriculum at Oslo University.
