title: [CHIP Germany: Impact of a Lifestyle Coaching Intervention on Nutritional Behaviour Change in Primary and Secondary Prevention of Type 2 Diabetes and the Importance of Social-Cognitive Variables].
abstract: Background:A high fibre and moderate fat diet can reduce the metabolic risk in diabetics. This study is the first one to test which social-cognitive variables affect nutritional behaviour changes in an educational lifestyle intervention.Patients and Methods:Subjects with diabetes or at high risk (intervention: N=43; control: N=40) joined an initial and a final individual health-coaching, an 8-week comprehensive lifestyle programme und a 10-month follow-up-period. Beside anthropometric, vital und clinical parameters (e. g., weight, HbA1c, FINDRISK), behavioural stages (preintenders, intenders, actors), outcome-expectancies, action planning and self-efficacy were evaluated for a healthy diet in both groups.Results:Weight, nutritional behaviour, self-efficacy, action planning, and outcome expectancies improved in the intervention group. Improved self-efficacy after the lifestyle programme was linked to weight reduction.Discussion:The metabolic risk profile was reduced by the educational lifestyle programme. A highly developed self-efficacy seems to help to change nutritional behaviour and therefore prevent and deal with diabetes.Conclusion:Behavioural lifestyle-coachings should focus on the volitional phase and implicitly improve self-efficacy.
