I lead the RHINESSA multi-generation study and an international transdisciplinary research network in this field.
Research

Biosketch: Cecilie Svanes is both a researcher and a practicing physician. Her daily clinical life inspires her research and she implements her research in her clinical work. She is driven both by a curiosity for the physiology of the human body, and by an urgency to contribute to improve health and prevent disease on a larger scale. Her PhD work became part of the established knowledge on peptic ulcer perforation and is referred to in the main textbooks and literature sources of surgery. Some of her research results led her into questioning the early life origins of health and disease, which became her focus when she made the move to respiratory medicine. In the European Community Respiratory Health Study and the linked Respiratory Health In Northern Europe study, she built up and led the research on early life origins of adult respiratory health and disease. New understanding in experimental research on epigenetic transfer of exposure effects through the male line, induced her to establish the multigeneration RHINESSA studies and build a world-leading trans-disciplinary environment on the preconception origins of respiratory health and disease, with particular focus on the fathers - the male line. For her pioneering work in these fields, she received in 2023 the great honor of being created Doctor Honoris Causa at Uppsala University. Her vision today is to disentangle the extent to which the environment and lifestyle of young boys and girls influence health and disease in their future offspring and subsequent generations – with the fantastic possibilities for efficient improvement in public health that such a paradigm would imply.

Some more detail: Cecilie Svanes, MD PhD is a Professor at the Centre for International Health (CIH), University of Bergen (UiB), and a Consultant in Pulmonary Medicine at the Department of Occupational Medicine, Haukeland University Hospital. She was created Honorary Doctor at Uppsala University in 2023 (Cecilie Svanes appointed to Honoray doctor at Uppsala University | Faculty of Medicine | UiB).

Her current research interests mainly focus on the fields of preconception and early life origins of respiratory health and disease. See description of selected reviews and original publications below.

Svanes conceived and currently leads the RHINESSA multi-generation study, which involves an international transdisciplinary research network on multi-generation research. She ileads the work on early life and multi-generation origins in the European Community Respiratory Health Study (ECRHS) and the affiliated Respiratory Health in Norther Europe (RHINE) study.

Currently Svanes is leading a project on pesticide and other environmental exposures in indigenous communities in Guatemala: Pesticides and exposures from traditional textile industry associated with own and offspring health in indigenous Guatemalan communities | Centre for International Health | UiB. See the descriptions of her projects for more information.

Svanes’ research results are disseminated widely, in scientific articles, textbooks of medicine and the media, and have contributed to scientific paradigm shifts, to impacting practice and guiding current health care policies (learn more: in English   in Norwegian). Svanes has published numerous much cited publications in high-impact journals. Her most important scientific contribution today concerns the preconception and transgenerational origins of allergies and lung health, while she has undertaken previous groundbreaking work regarding the early life origins of adult asthma, allergy and lung function.

A three-generation study on the association of tobacco smoking with asthma. Accordini S, Calciano  L, Johannessen  A, Portas  L, Benediktsdóttir  B, Bertelsen  RJ, Bråbäck  L,  Carsin  AE, Dharmage  SC, Dratva  J, Forsberg B, Gomez Real  F, Heinrich  J, Holloway  JW, Holm  M, Janson C, Jögi R, Leynaert B, Malinovschi A, Marcon A, Martínez-Moratalla Rovira J, Raherison C, Sánchez-Ramos JL, Schlünssen V, Bono R, Corsico  AG, Demoly  P, Dorado Arenas S, Nowak D, Pin  I, Weyler  J, Jarvis  D, Svanes C. Int J Epidemiol. 2018 Aug 1;47(4):1106-1117.

This paper, published with an editorial praising the methodology, demonstrated that fathers who started smoking before age 15 years were more likely to have children with asthma, confirming results from the paper described below on father’s preconception smoking and offspring asthma in a different cohort and using more advanced statistical methods..

Father's environment before conception and asthma risk in his children. Svanes C*, Koplin J*, Skulstad SM, Johannessen A, Bertelsen RJ, Benediktsdottir B, Bräback L, Carsin AE, Dharmage S, Dratva J, Forsberg B, Gislason T, Heinrich J, Holm M, Janson C, Jarvis D, Jögi R, Krauss-Etschmann S, Lindberg E, Macsali F, Malinovski A, Modig L, Norbäck D, Omenaas E, Saure EW, Sigsgaard T, Skorge TD, Svanes Ø, Torén K, Schlünssen V, Real FG.  Int J Epidemiol. 2017 Feb 1;46(1):235-245. Published with editorial.

This is a seminal paper. It was the first research to uncover that a father’s environment years and decades before the conception of his future children, was associated with much higher asthma risk in these future offspring. The paper also was a first to identify that a father’s puberty period is important for his offspring’s development of asthma. The paper identified 2 critical factors: fathers who started smoking before age 15 years, and fathers whose occupation involved welding. Cited: 35. This paper has also been presented more than 600 times is popular media around the world, including TIME magazine.

Birth characteristics and asthma symptoms in young adults: results from a population-based cohort study in Norway. Svanes C, Omenaas E, Heuch JM, Irgens LM, Gulsvik A. Eur Respir J. 1998 Dec;12(6):1366-70. doi: 10.1183/09031936.98.12061366. PMID: 9877492

The presentation of this paper at the American Thoracic Society congress in 1997 resulted in extensive press coverage. While today the early life origins of health and disease is generally accepted and implemented in mother and child care programs across the world, this seminal paper was the start of a major scientific effort to learn more about how adult lung health and disease originates early in life.

The “hygiene hypothesis” - early days

Childhood environment and adult atopy: results from the European Community Respiratory Health Survey.  Svanes C, Jarvis D, Chinn S, Burney P. J Allergy Clin Immunol. 1999 Mar;103(3 Pt 1):415-20. doi: 10.1016/s0091-6749(99)70465-3. PMID: 10069874. 

This paper contributed to a paradigm shift in the understanding of the relationship between pets and allergies. While pets had previously been considered to cause allergies in children, this paper found less atopic sensitization in those with childhood pets, in particular those with a dog. Later research supports these early results and suggests that pet keeping during childhood might protect against allergies by increasing microbial diversity. This paper has been widely cited and included in guidelines regarding pet keeping.
