British Medical Association British Medical Journals’ Archives of Disease in Childhood published his paper on screen time as its Leading Article. His paper on screen dependency was published in Britain's Royal College of General Practitioners' British Journal of General Practice. An article on the role of play in paediatric outcomes and disease prevention is published in the specialty group of the Royal College of Paediatrics and Child Health's BACCH News: Annual Scientific Meeting Special Issue.
Summer 2018, the Public Council under the President of the Russian Federation recently invited Dr Sigman to lecture to them and to then speak to faculty at Moscow State University on child screen time and screen dependency disorders. He was also invited to speak to the President of State Academy of Science, Russian Academy of Education.
Dr Sigman’s biology paper A Source of Thinspiration?, on the biological aspects of media, body image and dieting, was published in The Biologist, the Journal of the Royal Society of Biology and selected as the '2012 Scientific Article' for the Biology A-level exam (Paper Ref: 6BI05/01).
The Royal College of Paediatrics and Child Health invited Dr Sigman to speak on Alcohol and Electronic Media at its Annual Conference in 2012, at a clinical and scientific session on Young Persons Health. On several occasions, he was invited to speak to scientists at the European Space Agency on screen time and other health education subjects.
He has written the Brain and Behaviour column for The Times Educational Supplement.
Scotland's national Violence Reduction Unit invited Dr Sigman to speak to the nation's police at their conference: Alcohol - fuel for violence? He was a keynote speaker at two Department of Health NHS conferences on alcohol: the North West Alcohol Conference 2011 and the North East Alcohol Office conference 'Calling Time on Second Hand Harm'. In 2012 he was invited by the Ministry of National Education to address the First International Congress of Technology Addiction in Istanbul.
He has acted as advisor to the Institute of Personnel Management on health and psychology issues and conducts seminars and public speaking.
Dr Sigman's books include Alcohol Nation, The Body Wars, The Spoilt Generation and Remotely Controlled: How Television is Damaging Our Lives. (see ‘books’ page)
He has published other papers. Well Connected?: The Biological Implications of 'Social Networking', is published in The Biologist, Vol 56(1), the journal of the Society of Biology.
(Note: This paper has been misrepresented by some news reports, websites and bloggers as claiming that social networking causes cancer or disease. This is not true. The paper addresses the extent to which time online may be displacing face-to-face contact, and that lack of social connection is associated with physiological changes, increased incidence of illness and higher premature mortality.)
His paper Visual
Voodoo, on the potential biological effects associated with excessive television viewing, also published in The Biologist, and his talk at the Houses of Parliament, caused widespread public debate.
Dr Sigman has also written and presented scientific documentaries for BBC1 and Radio 4 on the scientific basis of faith; the biology of 'hypnosis'; and on the effects of too much choice, and for Dispatches on Channel 4 on the potential hidden detrimental effects of moderate dieting. He was invited to speak at the Edinburgh International Festival and to debate at an event held by the Spectator at The Royal Institution.
Dr Sigman comes from a medical family of three generations of professors of surgery. His grandfather was a professor of urology and his father was Dean of the University of Connecticut School of Medicine. One of his brothers is Chairman of the Division of Urology at Brown University Medical School in Rhode Island, Professor of Surgery, Professor of Pathology and Laboratory Medicine and Chief of Urology at its teaching hospitals. Another brother is a professor at Columbia University in New York, where he is Director of the Center for Applied Probability and Director of Undergraduate Programs.
