More than 14,500 young people born in the greater Bristol area between April 1991 and December 1992 have been involved in Children of the 90s since before they were even born. If you are one of the Children of the 90s, we’d like you to take part in Focus@24+ our first Focus visit for seven years. 

Focus@24+ started in June 2015 and will run until autumn 2017. If you've received your invitation, you can book your appointment online by clicking the button below (you will need the username and password included in your invitation pack):

What's involved

Informed consent: a fieldworker 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 withdraw from 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. 

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.

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

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

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

Lung function: blowing into a mouthpiece for as long and as hard as you can, once before and once after inhaling an asthma drug called salbutamol (Ventolin). You can choose not to have the salbutamol in which case we will just ask you to blow into the mouthpiece once.

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.

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.

Once you have completed your visit, which should take about four and a half hours, we will reimburse you for your travel expenses and give you a £30 shopping voucher to compensate you for your time.
