Brief Summary:
The increasing prevalence of type 2 diabetes mellitus is a worldwide problem. In preventing risk factors and unhealthy lifestyle through improved health literacy, chances are seen to delay or even avoid type 2 diabetes mellitus. The aim of the DIMINI-project is to prevent type 2 diabetes mellitus and to strengthen the health literacy of people at increased risk of developing it. For this purpose, people at increased risk are first identified by using the standardized screening tool Finnish Diabetes Risk Score (FINDRISC) adapted for Germany. Identified risk persons then receive a needs-based, modular lifestyle intervention including nutrition tips and physical exercises either paper- or app-based.

Condition or disease Intervention/treatment Phase
Health Behavior Health Knowledge, Attitudes, Practice Literacy Diabetes Mellitus, Type 2 Diabetes Behavioral: DIMINI lifestyle intervention Not Applicable

Detailed Description:
DIMINI, a randomised controlled trial, will assess whether the implementation of a lifestyle intervention for people at increased risk of developing type 2 diabetes mellitus will result in an improvement in body weight (primary outcome) and participants health literacy (secondary outcome) or not. A three-month intervention in the intervention group is followed by a one-year follow-up. The control group receives standard care as provided by the German statutory health insurance for three months and a one-year follow-up as well.

Arm Intervention/treatment
No Intervention: Control Group
The control group will receive standard care as provided by the German statutory health insurance.
Experimental: Intervention group
The intervention group receives the DIMINI lifestyle intervention for a period of three months.
Behavioral: DIMINI lifestyle intervention
DIMINI lifestyle intervention consists of the DIMINI-kit which contains health information, a list of food recommendations with additional information on calories, serving size and weight (traffic light rating system), a nutrition and an exercise diary. Participants in the intervention group can choose between a paper-based version or an app-based version of the DIMINI-kit. In addition, the kit includes an elastic exercise band with exercise poster, a measuring tape for self-control of the waist size and a pedometer.

Primary Outcome Measures :
  1. Body weight reduction [ Time Frame: 15 Months ]
    Survey of weight general practitioners level

Secondary Outcome Measures :
  1. Health literacy (European Health Literacy Survey Questionnaire) [ Time Frame: 15 Months ]

    Summed scale:

    • Maximum: 16 (best health literacy)
    • Minimum: 0 (worst health literacy)
    • ≥ 13 = sufficient health literacy
    • 9-12 = problematic health literacy
    • ≤ 8 = inadequate health literacy Higher values represent a better outcome

  2. Eating behaviour (German questionnaire on eating behaviour) [ Time Frame: 15 Months ]

    Three summed subscales:

    Scale 1) cognitive control of eating behavior, restrained eating

    • Minimum score: 0 = no cognitive control
    • Maximum score: 21 = extreme cognitive control Scale 2) disturbance of eating behavior
    • Minimum score: 0 = no disturbance
    • Maximum score: 16 = extreme disturbance Scale 3) experienced feelings of hunger
    • Minimum score: 0 = no disturbing sensations of hunger
    • Maximum score: 14 = very strong disturbing sensations of hunger For each item it is determined individually, which response option is considered to get a value of 1 or a value of 0 (e.g. Scale 1 Item 12: "true" = 1, "not true" = 0, Item 18 "true" = 0, "not true" = 1)

  3. Physical activity (International Physical Activity Questionnaire) [ Time Frame: 15 Months ]

    Questionnaire designed for population surveillance of physical activity among adults including

    Total Score:

    • Maximum Score: 960 minutes
    • Minimum Score: 10 minutes

    Categorical Score:

    Category 1 - Low:

    • Individuals who not meet criteria for Categories 2 or 3

    Category 2 - Moderate:

    • 3 or more days of vigorous-intensity activity of at least 20 minutes per day
    • 5 or more days of moderate-intensity activity and/or walking of at least 30 minutes per day
    • 5 or more days of any combination of walking, moderate-intensity or vigorous intensity activities achieving a minimum total physical activity of at least 600 minutes/week.

    Category 3 High

    • vigorous-intensity activity on at least 3 days achieving a minimum total physical activity of at least 1500 minutes/week
    • 7 or more days of any combination of walking, moderate-intensity or vigorous-intensity activities achieving a minimum total physical activity of at least 3000 minutes/week.

  4. Quality of life [ Time Frame: 15 Months ]
    Short Form 12
