Brief summary
Aim: To examine the effect of a brief theory-based health promotion intervention delivered in the community on health behaviour and diabetes-related risk factors among Danish adults at high risk of diabetes. Methods: A randomised trial was conducted among 127 individuals aged 28 to 70 with fasting plasma glucose: 6.1-6.9 mmol/l and/or HbA1c : 6.0-\<6.5% (42- \< 48 mmol/mol) recruited from general practice in Holstebro, Denmark. Participants were randomised to a control group or to receive the intervention delivered over four 2 h group sessions during five weeks, and two further sessions after one and six months. Questionnaire data and clinical measures were collected at baseline, three months and one year after intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| weight | baseline to one-year follow-up | change in weight / the proportion with weight reduction \>5% of baseline weight at one-year |
| total-fat intake <30% of energy intake | change from baseline to one-year follow-up | Information on diet was obtained using a validated self-administrated 198-item food frequency questionnaire (FFQ), the Inter99 FFQ. Portion size was set according to gender. Daily nutrient intake was translated into energy intake and nutrient intake using the Danish Food Com- position Databank (version 7.01) and the software program FoodCalc version 1.3 |
| saturated-fat intake <10% of energy intake | change from baseline to one-year follow-up | Information on diet was obtained using a validated self-administrated 198-item food frequency questionnaire (FFQ), the Inter99 FFQ. Portion size was set according to gender. Daily nutrient intake was translated into energy intake and nutrient intake using the Danish Food Com- position Databank (version 7.01) and the software program FoodCalc version 1.3 |
| fibre-intake ≥15g/1000kcal changes in physical activity level. | change from baseline to one-year follow-up | Information on diet was obtained using a validated self-administrated 198-item food frequency questionnaire (FFQ), the Inter99 FFQ. Portion size was set according to gender. Daily nutrient intake was translated into energy intake and nutrient intake using the Danish Food Com- position Databank (version 7.01) and the software program FoodCalc version 1.3 |
| changes in physical activity. | change from baseline to one-year follow-up | Physical activity was measured using the International Physical Activity Questionnaire (IPAQ). Increased MET (min/week)=increased physical activity |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| patient activation | change from baseline to one-year follow-up | patient activation was measured using the Patient Activation Measure (PAM) |
| cholesterol | change from baseline to one-year follow-up | Total, LDL, HDL, Blood tests were analysed in a central laboratory. |
| waist circumference | change from baseline to one-year follow-up | Waist circumference was recorded as the average of two measurements of waist circumference using a tape measure halfway between the lowest point of the rib cage and the anterior supe- rior iliac crests when standing. |
| total energy intake | change from baseline to one-year follow-up | Information on diet was obtained using a validated self-administrated 198-item food frequency questionnaire (FFQ), the Inter99 FFQ. Portion size was set according to gender. Daily nutrient intake was translated into energy intake and nutrient intake using the Danish Food Com- position Databank (version 7.01) and the software program FoodCalc version 1.3 |
| blood pressure, systolic and diastolic | change from baseline to one-year follow-up | Systolic and diastolic blood pressure was calculated as the mean of three measurements performed after at least 10 min rest, while participants were seated with the cuff on the right arm at the level of the heart. |
| HbA1c | change from baseline to one-year follow-up | Blood tests were analysed in a central laboratory. |
