The Christchurch Health and Development Study (CHDS) has been in existence for over 40 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 in mid-1977.

The cohort has been studied from infancy into childhood, adolescence and adulthood. Data gathered over the course of the study now comprises some 50 million characters of information, with which the study has published over 500 scientific papers, reports, books and book chapters describing the life history of the CHDS cohort.

In 2019, we completed our participant interviews for their 40-year assessment.
