Wales faces many health challenges.
People are living longer, but one in three adults say that their daily activities are limited by a health problem and one in two people over 65 are being treated for two or more health conditions.
There are many studies taking place to address these issues, but researchers find it difficult to recruit enough people.
Register online or by phone to say that you are willing to take part in research. This takes no more than 10 minutes.
Complete short questionnaires every 6 months, so that we get an ongoing picture of your lifestyle and health.
We'll let you know when there are new studies to join; you choose whether to take part or not.
