The Christchurch Health and Development Study (CHDS) has been in existence for over 35 years.

During this time we have followed the health, education and life progress of a group of 1,265 children born in the Christchurch (New Zealand) urban region during mid-1977.

This cohort has now been studied from infancy into childhood, adolescence and adulthood.

The data gathered over the course of the study now comprises some 50 million characters of information, with which the study has published over 435 scientific papers, reports, books and book chapters describing the 35-year life history of the CHDS cohort.
