Brief summary
Overweight and obesity is a growing problem in the world. Today more than 50 % of all people over 18 years in Sweden are overweight or obese. Main reasons for this are changes in lifestyle habits regarding diet and physical exercise. Overweight and obesity increases risk of different diseases such as type 2 diabetes, arthrosis and cancer; it also affects quality of life. Losing 5-10 % of your body weight improves metabolic health and quality of life. Lifestyle changes are very important in order to lose weight but it can be challenging to carry through with these changes on your own without support. In the primary care in Region Orebro län a group treatment, Step by step, has been in use since 2010. It comprises of six group sessions over 6-8 months with different themes such as diet, physical exercise and stress. Between the group sessions there are home assignments, such as writing a diet or exercise diary. This observational study will evaluate Step by step and the effect the group treatment has on the participants' weight, dietary habits, physical activity, quality of life, eating habits and metabolic health.
Interventions
BEHAVIORALA group-based treatment of overweight and obesity
The intervention is a group treatment of overweight and obesity in primary care inspired by cognitive behavioural therapy. The main goal of the group treatment is for the participants to obtain and maintain healthy lifestyle habits, with emphasis on diet and physical activity. Every group has 8-12 participants and is led by two persons; the main group leader is either a primary care nurse or a physiotherapist with special training. The groups meet six times (2 hours every time) once a month over a 6-8 month period. Every group session has a set agenda with different topics, for example a healthy diet, recommended physical activity or how to deal with setbacks. Between group sessions there are home assignments. The home assignments are followed-up at the next session and participants are encouraged to share experiences with each other in order to inspire, challenge and help fellow group participants. Data is collected prior to the start of group treatment, after 6-8 and 12 months.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Weight reduction in kg and % from baseline to 6-8 months and 12 months. | Change from baseline to follow-up at 6-8 months and 12 months. | Measured in kilograms |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Physical activity | Change from baseline to follow-up at 6-8 months and 12 months. | Measured by accelerometer. |
| Change in general Health-related Quality of Life | Change from baseline to follow-up at 6-8 months and 12 months. | Measured by Rand 36-item Health survey.

Subscale scores range from 0 to 100, where higher scores represent better health status. |
| Change in Obesity-specific Health-related Quality of Life | Change from baseline to follow-up at 6-8 months and 12 months. | Measured by the Obesity-Related Problems scale (OP V1.2). Comprises 8 items with a response choice from 1-4: 1 = Definitely bothered, 2 = Mostly bothered, 3 = Not so bothered and 4 = Definitely not bothered.

| Change in blood triglycerides | Change from baseline to follow-up at 6-8 months and 12 months. | Measured by blood test: triglycerides |
| Change in Systolic and Diastolic Blood pressure | Change from baseline to follow-up at 6-8 months and 12 months. | Measured by measuring the blood pressure. |
