Obesity: identification, assessment and management

Measurements for assessing health risks in adults: What are the most accurate and suitable measurements and boundary values to assess the health risks associated with overweight, obesity and central adiposity in adults of different ethnicities, particularly those from Black, Asian and minority ethnic family backgrounds?

Measurements for assessing health risks in children and young people: What are the most accurate and suitable measurements and boundary values to assess the health risk associated with overweight, obesity and central adiposity in children and young people of different ethnicities, particularly those from Black, Asian and minority ethnic family backgrounds?

Follow-up care after bariatric surgery: Do post-operative lifestyle intervention programmes (exercise, behavioural or dietary) improve weight loss and weight-loss maintenance following bariatric surgery?

What is the effectiveness and cost effectiveness of bariatric surgery in achieving weight loss and improving treatment outcomes in people who are unable to receive treatment for other health conditions (such as joint replacement surgery or fertility treatment) because they are living with obesity? 

Long-term outcomes of bariatric surgery on people with type 2 diabetes: What is the long-term effect of bariatric surgery on diabetes-related complications and quality of life in people with type 2 diabetes compared with optimal medical treatment?

What is the effectiveness and cost effectiveness of bariatric surgery in achieving weight loss and maintaining a healthier weight in adults from minority ethnic family backgrounds who are living with obesity? 

Bariatric surgery in children and young people: What are the long-term outcomes of bariatric surgery in children and young people living with obesity?

Obesity management for people with a condition associated with an increased risk of obesity: What is the best way to deliver obesity management interventions to people with particular conditions associated with increased risk of obesity (such as people with a physical disability that limits mobility, a learning disability or enduring mental health difficulties)?

Long-term effect of very-low-calorie diets on people with a BMI of 40 kg/m2 or more: What are the long-term effects of using very-low-calorie diets (VLCDs) versus low-calorie diets (LCDs) on weight and quality of life in patients with a body mass index (BMI) of 40 kg/m2 or more, including the impact on weight cycling?

Comparative risks for different generations of immigrants: Is the risk of ill health the same for first-, second- and third-generation immigrants from black, Asian and other minority ethnic groups at the same BMI and waist-to-height ratio thresholds?

Single cut-off points: What are the risks and benefits of developing single-figure cut-off points on BMI and waist-to-height ratio for black, Asian and other minority ethnic groups to help prevent diabetes and other conditions?

Awareness of risk among black, Asian and other minority ethnic groups: Are black, Asian and other minority ethnic groups aware that they are at the same risk of type 2 diabetes and mortality at a lower BMI, compared with the white population?

Practitioners and providers' awareness of risk in black, Asian and other minority ethnic groups: Are clinicians, practitioners and weight management service providers aware that black, Asian and other minority ethnic groups are at the same risk of type 2 diabetes and mortality at a lower BMI compared with the white population. If so, do they intervene at lower BMI and waist-to-height ratio thresholds?

Lifestyle interventions for black, Asian and other minority ethnic groups: How effective and cost effective are lifestyle interventions for people from black, Asian and other minority ethnic groups at different BMI and waist-to-height ratio thresholds, compared with the general population?
