Scientific title | Effect of communicating genetic and phenotypic risk for type 2 diabetes in combination with lifestyle advice on objectively measured physical activity: a randomised controlled trial |
Study acronym | DRCT |
Study objectives | The primary objective of the DRCT is to assess the effects of providing: 1. A genetic risk estimate for type 2 diabetes in combination with standard lifestyle advice and 2. A phenotypic risk estimate for type 2 diabetes in combination with standard lifestyle advice on objectively measured physical activity |
Ethics approval(s) | Cambridgeshire 1 Research Ethics Committee, 21/10/2010, ref: 10/H0304/78 |
Health condition(s) or problem(s) studied | Type 2 diabetes/physical activity/risk communication |
Intervention | Participants are randomly allocated to one of three groups: Intervention Group A: Participants receive a genetic risk estimate for type 2 diabetes based on 23 single nucleotide polymorphisms Intervention Group B: Participants receive a phenotypic risk estimate based on age, sex, body mass index, family history of diabetes, smoking status, and prescription of steroid or anti-hypertensive medication Control Group: Participants do not receive either of the risk estimates until after they have completed follow-up Each group will receive standard lifestyle advice, which includes general information about type 2 diabetes as well as information about how to reduce the risk of developing the disease. |
Intervention type | Other |
Primary outcome measure | Objectively measured physical activity energy expenditure over 1 week (8 weeks post-intervention), assessed using an Actiheart® |
Secondary outcome measures | 1. Self-reported diet 2. Self-reported weight 3. Intentions to be physically active and to engage in a healthy diet 4. Anxiety 5. Diabetes-related worry 6. Self-rated health 7. Self-reported sedentary behaviour 8. Cognitive and emotional theory-based antecedents to health behaviour change |
Overall study start date | 11/02/2011 |

Target number of participants | We aim to collect outcome data on approximately 465 participants. Thus, assuming a 20% attrition rate, we will randomise approximately 580 participants in total. |
Key inclusion criteria | Residents of Cambridgeshire, in the east of England, born between 1950 and 1975, are potentially eligible to participate in the Fenland Study. Participants of the Fenland Study are invited to take part in the DRCT if they: 1. Agreed to be contacted regarding potential involvement in future studies 2. Provided sufficient data to calculate genetic and phenotypic risk estimates for type 2 diabetes 3. Wore an Actiheart® for 3 or more full days without experiencing a severe rash 4. Returned an Actiheart® that recorded 36 or more hours of total data |
Key exclusion criteria | Residents of Cambridgeshire are excluded from the Fenland Study by their GP if they: 1. Have diagnosed diabetes 2. Have a medical condition with a prognosis of less than 1 year 3. Suffer from psychotic illness 4. Are pregnant or lactating 5. Are unable to walk unaided After participating in the Fenland Study, participants are excluded from the DRCT if they: 1. Have diagnosed diabetes 2. Are actively participating in another study |
