Children of the 90s is what’s known as a longitudinal study – research that follows the same group of people over time. So, while you share a common experience with everyone else in the study (being born in the Bristol area between April 1991 and December 1992), how your life has unfolded since you were born is unique to you. This makes you irreplaceable, and any data and information you share with us now is as valuable to researchers as it was at the start of our study. The study’s data and samples are helping us to learn about COVID-19, cancer, obesity, heart disease and mental health and more. Put simply, it’s never too late for participants of all ages to get involved again, however long you’ve been away!

We understand how busy life can be, so how much time you commit is entirely up to you – you can choose to do as much or as little as you like. Whether it's completing questionnaires, visiting a clinic, or keeping a food/fitness diary for months at a time, just let us know how and when you’d like to take part and we’ll make sure we only contact you with relevant information.

You will be offered an incentive (for example, a shopping voucher) every time you complete a questionnaire or come to clinic, though it’s up to you whether you choose to receive these. We’ll also reimburse your travel costs and even pay for your accommodation if you've travelled a long way to attend a clinic. 

We are currently running the @30 clinic, as we celebrate our 30th year of Children of the 90s. This is our biggest clinic in participant numbers as everyone enrolled in the study has been invited to take part. Whether you are an original mum or dad, a Child of the 90s (aged around 30) or a child of a Child of the 90s, you are invited to attend. We also have our regular questionnaires, which are available to complete either on paper or online. You can find out how you can get involved by emailing info@childrenofthe90s.ac.uk or follow our social media channels.

As well as the information you give us via questionnaires and at clinic, we also collect data from your digital records (for example, your NHS records and information about any benefits you may receive). This is called data linkage and it is extrememly valuable for research. Data linkage gives us information that is otherwise difficult to obtain, and information that you may not even know yourself (for example, exact doses of medicine you have been prescribed). Read more about the ways in which we use and safeguard this data (and how to tell us if you do not want us to use these records).

Absolutely! In recent years, we have been following a growing number of Children of the Children of the 90s (COCO90s), making us the only project we know of to provide scientists with information on three generations. Whatever age your children are, we’d love them to get involved too. Likewise, if you or your partner are pregnant, then please do let us know. 

Of course, we’d love to hear from you. Please text 07772 909090 with your full name and date of birth or drop us a line (info@childrenofthe90s.ac.uk). We look forward to hearing from you.
