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 trialwas conducted among 127 individuals aged 28 to 70 with fasting
plasma glucose: 6.1–6.9 mmol/l and/or HbA1c: 6.0–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. Primary outcomes;
total-fat intake 15 g/1000 kcal; weight reduction >5%; changes in physical activity.
Results: 85% attended one-year follow-up. After adjusting for gender, age and education,
Odds ratio (OR) (95% CI) intervention vs control: total-fat intake 0.52 (0.22;1.20), saturated-fat intake ≥15 g/1000 kcal: 1.18 (0.48;2.92), weight reduction >5%: 2.47 (0.95;6.39). ˇ(95% CI) between
intervention vs control in changes from baseline: IPAQ, MET min/week: −236 (−2760; 2288),
waist circumference,cm: −2.5 (−4.5; −0.5); systolic blood pressure, mmHg: −4.6 (−8.8; −0.3).
Conclusion: A brief theory-based health promotion intervention delivered in the community
indicated effect on weight, waist circumference and systolic blood pressure at one year
among Danish adults at high risk of diabetes. No effect was shown on diets or physical
activity.
