Background and study aims Obesity is a growing major threat to public health, but there is limited evidence for interventions that could easily be applied, with relatively little training, in primary care, where most obesity is managed. The internet could potentially provide an ideal way to give patients interactive advice based on their personal situation and progress, with the support of a nurse to oversee, encourage, advise patients as necessary. Among obese patients in primary care, we aim to estimate the effectiveness and cost-effectiveness of a) an internet based behavioural intervention with face to face support as needed and b) an internet behavioural intervention with minimal face to face support. Who can participate? If you are registered with one of the recruiting GP practices you may be written to, or your general practitioner (GP) or Practice Nurse may ask you if you would like to take part if you attend an appointment with them. You must have a Body Mass Index (BMI) of over 30 or 28 with high blood pressure or high cholesterol, to take part in the study. What does the study involve? In order to take part in this study you must have regular access to the internet at home, at work or possibly a public place such as a library. First of all you will attend a screening appointment with your practice nurse, where some measurements will be made and a blood sample taken. All patients in the study will have these same measurements made again 6 months and 12 months after this first appointment. There are three possible groups that you could be randomly allocated to: Web Intervention with nurse support- if in this group you will use the POWeR2 website and also visit the practice nurse at 2 weeks, 6 weeks and 3 months after the first visit. You may have four extra visits if needed. Web intervention with minimal nurse support – if in this group you will use the POWeR2 website and have a brief visit with the practice nurse at 2 weeks and then have three online contacts from the nurse at 1, 2, and 3 months and up to 2 telephone calls. Very brief advice and follow up – if you are in this group the practice nurse will give you some brief advice about a healthy diet and physical activity. You will only visit the practice nurse at 6 and 12 months for weight measurement and a blood sample. What are the possible benefits and risks of participating? By taking part in this study there is a chance that you will lose weight. Making gradual changes to your diet or physical activity levels should not present any risks to you, although if you are diabetic you may need to alter your medications, your practice nurse will advise you if this is necessary. If you have any questions or concerns about your health or your medications while on the programme, the practice nurse will be available to advise you. Where is the study run from? The study is co-ordinated from the Dept. of Primary Medical Care, University of Southampton. Patients will be recruited from about 44 practices within Southern England. When is the study starting and how long is it expected to run for? The study will begin recruiting patients from February 2013, for 6 months. Patients recruited into the study will be in the study for 12 months. Who is funding the study? National Institute for Health Research (NIHR) Health Technology Assessment Programme (UK) Who is the main contact? Jo Kelly [email protected]
