Declining Fertility Rates and Advanced Parental Age at Childbirth

Fertility rates are declining across the world, and advanced parental age at childbirth is increasing. This has implications for pregnancy outcomes, parental and child health. Combining nationwide registries and other large data bases with linked information on demographics and health outcomes, allows for long term follow up of perinatal outcomes and birth characteristics. The availability of IDs from parents enables use of family designs and investigations of familial clustering of outcomes.

Siri Håberg will present examples and discuss:

  • Why are fertility rates declining?
  • Why is advanced parental age important for pregnancies and child health outcomes?
  • Health implications of Assisted Reproductive Technologies – new research plans
  • Are intervals between pregnancies important for outcomes?

Speaker Profile Siri E. Håberg is a MD PhD and the deputy director of the newly established Centre for Fertility and Health, a new Centre of Excellence granted the Norwegian Institute of Public Health. This research centre is an interdisciplinary research centre focusing on changes in fertility and family structures during the past decades, combining epidemiology, demography, genetics and medicine. Her main research interest is in perinatal epidemiology, and in particular fertility problems, assisted reproductive technologies and causes of unsuccessful pregnancies. The CHALLENGE platform invited Siri to Copenhagen as she is part of the Scientific Advisory Board due to her extensive experience with register based research, and in combining data from cohort studies, biological analyses and national registries.

Seminar Profile Welcome to the new Seminar Series in Life Course and Ageing. With these seminars we wish to nurture a common interest in life course and ageing across sections, identify potential partners for new collaborations, and to expand the breadth of our knowledge on life course and aging. The seminars will include speakers from Department of Public Health as well as a range of external speakers. These seminars are organized in collaboration between Section of Social Medicine, Section of Epidemiology, and Section of Environmental Health. We aim for four annual seminars. Always feel free to contact Charlotte Nilsson ( with ideas for topics or speakers.
