This is a follow-up survey of women, 10-12 years after they were included in the population-based Stork Groruddalen study of pregnant women, primarily set up to study gestational diabetes and related health issues in pregnancy in a multiethnic population. The investigators will now update the information about the health status of these women to study the development of risk factors for type 2 diabetes and cardiovascular diseases.

The STORK-Groruddalen is a cohort study of 823 pregnant women. Participation rate was high due to facilitation for ethnic minorities and data collection at the local Health Centres, set up to study ethnic differences in health to inform prevention strategies to reduce these differences. The investigators have published many papers from this well charatertized cohort, about gestational diabetes and related health issues in pregnancy. Participants have agreed to be contacted for subsequent follow-up surveys.

The inivestigators are now planning a follow-up study of these woman during 2019-2022, to study trajectories for risk factors for type 2 diabetes and cardiovascular diseases such as BMI, blood pressure, lipids, behavioural factors, physical activity and mental health and other health issues. The investigators will collect selfreported information through questionnaires, perform clinical measurements and take blood samples and buccal swabs. Collecting updated information about a range of health outcomes for women in this cohort will, together with already collected data, enable us to study the development of risk factors for type 2 diabetes and cardiovascular diseases in a life course perspective.
