Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Cancer
  • Pregnancy

His primary scientific interests are in Pregnancy, Cohort study, Pediatrics, Obstetrics and Epidemiology. Jørn Olsen has included themes like Odds ratio, Gynecology, Confidence interval and Risk factor in his Pregnancy study. The study incorporates disciplines such as Offspring, Overweight, Hazard ratio, Prospective cohort study and Attention deficit hyperactivity disorder in addition to Cohort study.

His Pediatrics research is multidisciplinary, incorporating elements of Injury prevention, Prenatal stress, Retrospective cohort study and Epilepsy. His studies in Obstetrics integrate themes in fields like Body mass index, Birth weight, Gestational age, Preeclampsia and Low birth weight. His biological study spans a wide range of topics, including Surgery, Incidence, Psychiatry, Public health and Cohort.

His most cited work include:

  • Randomised study of screening for colorectal cancer with faecal-occult-blood test (2169 citations)
  • The Danish National Hospital Register. A valuable source of data for modern health sciences. (1840 citations)
  • Maternal age and fetal loss: population based register linkage study (1083 citations)

What are the main themes of his work throughout his whole career to date?

Jørn Olsen focuses on Pregnancy, Cohort study, Obstetrics, Pediatrics and Epidemiology. Jørn Olsen focuses mostly in the field of Pregnancy, narrowing it down to matters related to Odds ratio and, in some cases, Case-control study. He interconnects Young adult, Demography, Hazard ratio, Cohort and Risk factor in the investigation of issues within Cohort study.

The concepts of his Obstetrics study are interwoven with issues in Body mass index, Birth weight, Abortion, Gestational age and Low birth weight. His Pediatrics study combines topics from a wide range of disciplines, such as Prenatal stress and Epilepsy. His Epidemiology study incorporates themes from Cancer, Surgery, Public health and Environmental health.
