NCT01947595

Brief Summary

The purpose of this prospective randomized multicenter intervention study is to determine whether in the prevention of Diabetes an intensified lifestyle intervention is superior to a conventional lifestyle intervention in high risk non-Responder subjects. Further, the intensive phenotyping to determine subgroups with an increased risk for diabetes enables an individualized prevention and therapy of type 2 diabetes mellitus.

Outcome Measures

Primary Outcomes (1)

  • postprandial glycaemia (2h plasma glucose level of the 75 g oral glucose tolerance test (OGTT))

    one year

Secondary Outcomes (3)

  • insulin sensitivity confirmed by 75 g oral glucose tolerance test (OGTT)

    one year

  • insulin secretion confirmed by 75 g oral glucose tolerance test (OGTT)

    one year

  • distribution of body fat confirmed by MR-Imaging and proton magnetic resonance spectroscopy by 3 T whole body imager

    one year

Other Outcomes (2)

  • metabolic and genetic characterization to determine the risk of type 2 diabetes confirmed by case history, clinical examination, venous blood sampling, DNA isolation, standardised questionnaires, bio-electric impedance analysis (BIA)and ergospirometry

    one year

  • metabolic and genetic characterization to determine the non-response to lifestyle intervention confirmed by case history, clinical examination, venous blood sampling, DNA isolation, standardised questionnaires,BIA, ergospirometry

    one year

Study Arms (4)

high risk non-responder, intensified lifestyle intervention

ACTIVE COMPARATOR

high risk non-responder: * A) reduced Insulin secretion (disposition index: (IGI \* ISI-Matsuda)\< 760) * B) insulin resistance (ISI-Matsuda \< 9,2) * C) elevated liver fat ( MRT \> 5,56%) * A+B or A+C or B+C or A+B+C

Behavioral: intensified lifestyle intervention

hight risk non responder, normal lifestyle intervention

ACTIVE COMPARATOR

high risk non-responder: * A) reduced Insulin secretion (disposition index: (IGI \* ISI-Matsuda)\< 760) * B) insulin resistance (ISI-Matsuda \< 9,2) * C) elevated liver fat ( MRT \> 5,56%) * A+B or A+C or B+C or A+B+C

Behavioral: normal lifestyle intervention

Behavioral: Single lifestyle advice

Interventions

* physical activity 6 hours per week, 50% guided activity * recorded by an accelerometer (Aipermotion 440) * 16 sessions per year with a lifestyle advisor * nutritional advice (target weight: 5% less, if BMI \> 25kg/m², less than 30% fat per caloric intake, less than 10% fatty acids per caloric intake, more than 15 g fibre per 1000 kcl)

high risk non-responder, intensified lifestyle intervention

* physical activity 3 hours per week * recorded by an accelerometer (Aipermotion 440) * 8 sessions per year with a lifestyle advisor * nutritional advice (target weight: 5% less, if BMI \> 25kg/m², less than 30% fat per caloric intake, less than 10% fatty acids per caloric intake, more than 15 g fibre per 1000 kcl)

Responder, normal lifestyle interventionhight risk non responder, normal lifestyle intervention

\- Single Health care advice and lifestyle advice (30 minutes) at the beginning * recommend the individual target weight (5% less, if BMI 25\> kg/m²)

Responder, single lifestyle advice (control group)
