The BIG challenge


A spotlight campaign on obesity research

With over 60 percent of the adult population either overweight or obese and more than 2.7 million people diagnosed with type 2 diabetes, the health burden and economic impact of obesity in the UK are increasing.

The National Institute for Health Research (NIHR) is currently supporting research into the condition across 43 obesity-related studies. We’ve selected four of these studies to give an insight into the experiences of patients and the work of researchers and health professionals across England.

This diverse set of studies will also help you better understand the range of ways the BIG challenge is being addressed by the research community. It’s also a sign of what’s to come.

The NIHR has just issued a national call for new research to address UK obesity levels. We’re asking the research community for innovative research for the prevention and treatment of obesity in adults and children. Find out more about the call.

Surgery

The By-Band-Sleeve study

Around 6,000 operations take place each year in the UK that are designed to help people lose weight. This is known as bariatric surgery. There are three types of bariatric operations, but it is unknown which one is the most effective option for patients in the long term because of a lack of good evidence. As a result, the choice of surgery in most hospitals is based on a combination of the patient’s and surgeon’s preference. But which operation is really most beneficial to long-term health, and which offers the most cost effective option for the NHS? By-Band-Sleeve is the biggest study of its type in the world addressing these questions. By taking part in the study, over 300 patients across England approved for bariatric surgery are already helping the research team work out which is the best choice: the gastric bypass, the gastric band, or the gastric sleeve…

Lifestyle

The ACUTE study

Over 2.7 million people are diagnosed with type 2 diabetes in the UK. It’s a condition that leads to a number of other health problems, for example if you’re affected you’re up to five times more likely to develop heart disease or have a stroke.

Currently, people at risk of developing type 2 diabetes are advised to take part in moderate-to-vigorous physical activity for at least 150 minutes a week. So that could be a brisk walk, or a fast bike ride. ACUTE is a study that explored a new way of addressing prevention of this condition amongst inactive, overweight or obese women.

The study found that breaking up prolonged bouts of sitting with just five minutes of standing or walking every 30 minutes significantly reduced blood sugar and insulin levels. Importantly, the effect of the activity lasted until the following day.

Mental Health

The STEPWISE study

People with schizophrenia are two to three times more likely to be overweight or obese than the general public. Weight gain can affect their lives in a range of negative ways. For example, it can lead to long-term health conditions such as diabetes and heart disease and it is thought obesity may also play an important role in stopping people taking their antipsychotic medication. The aim of the STEPWISE study is to find out if a lifestyle education programme can help people with schizophrenia manage their weight more effectively. It is also designed for people who have recently experienced their first psychotic episode, so the study team can look at the prevention of obesity, not just its treatment.

The programme is based on a lifestyle intervention originally developed by the University of Leicester DESMOND team, to reduce the risk of type 2 diabetes. It includes four weekly sessions with clinicians and follow up sessions after three, six and nine months all focussing on diet and exercise.

Brain Imaging

Brain imaging studies

People’s brains respond to food in different ways, and it is this relationship that provides the foundation for Dr Tony Goldstone’s brain imaging research. Dr.Goldstone uses magnetic resonance imaging (MRI) of the brain to see how it is affected by obesity, gut hormones and weight-loss treatments. Studies examine:

  • Effects of being hungry – for example when fasted compared to having eaten a meal;
  • Gut hormones – for example when given an injection of a hormone that alters appetite;
  • Different diets or surgical treatments for obesity (e.g. gastric bypass and gastric banding).
