More than 14,500 young people born in the greater Bristol area between April 1991 and December 1992 have taken part in Children of the 90s since before they were even born. 

If you are one of them, we’d like you to come to our Focus@24+ clinic. You can book a short appointment (about two hours) or a longer appointment (about four and a half hours), and come in after work or at the weekend. We’d love to see you.

What's involved

If you book a two-hour clinic, we will ask you to complete a questionnaire online before your visit (this will take about an hour). We will then ask you to do the following sessions during your visit: 

Informed consent: a member of staff will explain all the sessions to you and answer any questions you may have. Then they will ask you to complete and sign a consent form. You choose how much or how little you'd like to do and you can stop doing any or all of the sessions at any time. 

Fasting blood sample: giving blood after not having eaten or drunk anything apart from water for at least six hours. 

Urine sample: giving a small urine (pee) sample (about 1/3 of a cup). 

Chlamydia screening: if you give us a urine sample, we will ask if you would like to have it tested for chlamydia and gonorrhoea by the National Chlamydia Screening Programme (NCSP).

Liver scan: having your liver scanned by ultrasound while you are lying on your back. 

Time for a break: after doing all or any combination of the above sessions it's time for a break and a light meal in our free cafe. 

DEXA scan: having first your whole body, then just your hip, measured while lying on your back on a scanning machine.

Body size and shape: having your weight, height (standing and seated), waist, arm and hip measured. 

Blood pressure and pulsehaving your blood pressure and pulse measured in different ways while you are sitting and standing.

Lung function: blowing into a mouthpiece for as long and as hard as you can.

Cognitive function tasks: completing two tasks (one paper-based and one face-to-face) to test your cognitive function.

Unusual experiences interview: answering some questions about any usual experiences or events.

Playing your part: consenting to us using your health and other official records if you are happy to and haven't already done so in the past.

Extra tests

If you choose to attend a longer clinic (about four and a half hours), you will be asked to complete the sessions listed as above, plus:

Questionnaire: completing a questionnaire on a computer during your visit (instead of doing it at home in advance).

3D whole-body scan: having your body's size, shape and posture measured while standing up in a three-dimensional (3D) machine that uses light scanners and computer software to produce the 3D image. There is no X-ray or radiation involved.

Lung function: after your initial lung function test, you will be asked to inhale an asthma drug called salbutamol (Ventolin). We will then ask you to blow into a mouthpiece again to test your lung function for a second time. 

Interviews and computer tasks: answering questions (some face-to-face, some on a computer) about a range of topics and completing tasks on a computer that look at your memory and how you make decisions and react emotionally to certain situations.
