What is the LOLIPOP 100k study?

The London Life Sciences Prospective Population 100K study (abbreviated to the “LOLIPOP 100K study” or “LOLIPOP 100K”) is a major UK research study investigating the mechanisms underlying heart disease stroke, diabetes, obesity and other major medical problems, with a particular focus on the South Asian community. Through the detailed baseline assessment and long-term follow-up of our ~100,000 volunteers we aim to identify the environmental and genetic factors that contribute to heart disease, stroke and other diseases, and to develop new tools for the identification of people at increased risk of ill-health.

Who is eligible to participate in the LOLIPOP 100K study?

We are recruiting mostly healthy volunteers recruited through their General Practitioners. We intend to sample both men and women, aged 18-85 years, with a focus on South Asians. We cannot include participants who are known to be pregnant, or who have a current or recent acute illness.

How do I register?

You can contact us by phone on 0204 542 8494 or book a slot here.

How long will the health check take?

It will take approximately 40-60 minutes.

Can you take walk-ins?

We do not accept walk-ins as this will affect other participants’ appointments. To avoid disappointment and reduce waiting time, you are strongly encouraged to contact us or click here to book an appointment.

If I have a medical condition or had a recent major injury/illness/surgery or am a cancer survivor, can I participate?

Unfortunately, the study is unable to include participants who are known to have a current or recent acute illness.

I am already enrolled in a study; can I still take part in this study?

Yes, you can participate if you are enrolled in another observational study that does not involve drug treatment. If you are involved in a drug trial, you should wait at least one month after completing the trial before making an appointment with LOLIPOP 100K.

Can I accompany my friends/relatives for the scheduled visit?


If I am going to turn 85 years old next month, can I still join the study?

We are recruiting participants aged 18-85 years, thus please book your appointment early with us before you turn 86 years old. We count your age as at the appointment date.

For the study to gain the most value we need to collect as much data as possible and we would appreciate every participant completing all the listed tests.
