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.
We've completed the first phase of our research into the effects of cannabis on the body!
With 50 participants from our cohort, we've been looking into how brain and heart activity, neuropsychological data, and biological markers are related to a history of cannabis use. We've been comparing people with a significant history of cannabis use with those who do not.
Participants have completed a short interview, a set of neuropsychological tests, blood tests for various biological markers and genetic data, and urine tests for the presence of cannabis and other drugs. They've also had MRI scans of the head and chest, looking at both the structure and function of these areas.
Thank you so much to everyone who's taken part. We're now about to start recruiting the next wave so will have some data to share soon! Please get in touch if you have any questions: email@example.com
