All participants in the RADIEL-study (2008-2011) who delivered (n=535), will be invited to this follow-up study, with their children (age 3-5 years) and the father. The investigations are carried out during two separate visits. The father receives mail questionnaires


  1. To determine the long-term effectiveness of a lifestyle intervention in high risk women and their offspring

    1. in reducing the incidence of T2DM and cardiovascular disease and their risk factors
    2. in preventing obesity
    3. on biomarkers
    4. on genetic and epigenetics markers .
  2. To study the association between maternal diet during pregnancy and metabolic markers in the offspring at age 3-5 years.
  3. To study the association between maternal exercise habits during pregnancy and metabolic markers in the offspring at age 3-5 years.
  4. To study the association between maternal a) glucose-insulin metabolism b) lipid metabolism c) adipoinsulinar axis and d) inflammatory markers and birth size and later health outcomes in the mothers and their offspring.
  5. To study the association between gut microbiota and markers of offspring health
  6. To study the cost effectiveness of the intervention.


Maternal measurements

  1. Height, weight, waist and hip circumference
  2. Blood pressure, pulse
  3. Body fat percentage
  4. Blood tests e.g. markers of glucose metabolism and lipids, vitamin D, Calcium and bone markers, DNA sample and inflammation markers
  5. Fecal and hair samples
  6. Diurnal salivary cortisol assessment
  7. Background questionnaire: socioeconomic and health-related background
  8. Health-related quality of life (15-D).
  9. 3-day food diary and exercise diary
  10. ArmBand (acceleration sensor), assessment of physical activity and sleep for 7 days
  11. Psychological questionnaires
  12. Pulse wave velocity (PWV) will be assessed
  13. Advanced glycation endproducts - a marker of cardiovascular health will be assessed

Paternal measurements

  1. Background questionnaire (incl. height, weight, age)
  2. DNA-sample (buccal)
  3. 3-day food diary
  4. Psychological questionnaires

Measurements of children

  1. Body weight, height, blood pressure, pulse
  2. Body fat percentage
  3. Psychological questionnaires
  4. Food and physical activities diaries
  5. ActiGraph, assessment of physical activity and sleep for 7 days
  6. Blood samples e.g. glucose- and insulin metabolism, lipids, vitamin D and Calcium, DNA-sample and samples for inflammation markers
  7. Fecal, urine and hair samples
  8. A copy of child welfare center card (e.g. data on growth, immunizations, health)
  9. Endothelial function and pulse wave velocity (PWV)


Follow up starts in January 2014, and will continue until 2018. Data analysis starts in 2016 and results will be reported from 2016 onwards in international peer-reviewed journals.

Radiel Intervention group and their children
Participated the Radiel- intervention study (2008-2011) in the Intervention group: Lifestyle counselling during and after pregnancy (up to 1 year post partum)
Radiel Control Group with their children
Control group in the Radiel- intervention study.


Ages Eligible for Study:   3 Years to 50 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Women who participated the Radiel intervention study, and were originally randomly assigned to either active lifestyle intervention group or control group. They were all high risk women with BMI >30 or prior gestational GDM. To this follow up-study we invite also the children born during the intervention.
