Published research based on the NIPH's health registries (2013/2014)

Published Updated


List of academic articles based on data from the Norwegian Institute of Public Health's health registries, published in 2013-2014.


Health registries

Health registries are an important tool to monitor the health status of the population. The Norwegian Institute of Public Health is responsible for several large health registries.

Researchers can apply for data from the Norwegian Institute of Public Health's health registries and health studies:

This is an overview of published articles (based on data from the registries) extracted from academic index databases. The search results rely on the registries being cited correctly in the summary. It may not be complete.
