Background and study aims
This study is part of a large multi-national diabetes prevention project which aims to identify the best lifestyle for the prevention of type 2 diabetes in a population of pre-diabetic overweight or obese individuals. The focus will be on diet (specifically protein and glycemic index) and physical activity, as well as their interaction with the lifestyle factors, habitual stress and sleeping patterns as well as behavioural, environmental, cultural, and socioeconomic factors.

Who can participate?
People of all age ranges and genders who participated in five studies: Lifelines (the Netherlands), the Nutrition Questionnaires plus (NQplus) study (the Netherlands), the Cardiovascular Risk in Young Finns Study (YFS; Finland), the New Zealand Adult Nutrition Survey 2008/09 (NZANS), and the Quebec Family Study (QFS; Canada).

What does the study involve?
Data is collected from the five studies, including dietary intake, in particular protein intake and glycemic index and load, physical activity and sleep duration, along with the prevalence and incidence of pre-diabetes, diabetes, and fasting blood sugar levels.

What are the possible benefits and risks of participating?
This study will increase knowledge on how specific lifestyle factors can help prevent type 2 diabetes. This study uses existing data from previous studies so there are no additional risks involved.

Where is the study run from?
Wageningen University (Netherlands)

When is the study starting and how long is it expected to run for?
January 2013 to December 2018

Scientific titlePREVIEW Population studies (PREVention of diabetes through lifestyle Intervention and population studies in Europe and around the World; Population studies)
Study objectivesThe primary goal of PREVIEW is to identify the most efficient lifestyle pattern for the prevention of type-2 diabetes in a population of pre-diabetic overweight or obese individuals. The focus will be on diet (specifically protein and glycemic index) and intensity of physical activity, as well as their interaction with the lifestyle factors, habitual stress and sleeping pattern as well as behavioural, environmental, cultural, and socioeconomic variables.
Ethics approval(s)Ethical approval was not necessary. The researchers did not have any access to personal information regarding the participants and all data that will be analyzed are based on harmonized variables and are completely anonymized. For the individual observational studies, all participants signed informed consent for the original study.
Health condition(s) or problem(s) studiedPre-diabetes (for the prevention of type 2 diabetes)
Intervention'PREVIEW Population studies' describes cross-sectional and longitudinal analyses from the five population studies included in PREVIEW: Lifelines (the Netherlands), the Nutrition Questionnaires plus (NQplus) study (the Netherlands), the Cardiovascular Risk in Young Finns Study (YFS; Finland), the New Zealand Adult Nutrition Survey 2008/09 (NZANS), and the Quebec Family Study (QFS; Canada). For Lifelines and NQplus baseline data and data from the first follow-up measurement will be used. For YFS, the 27-year follow-up from 2007-2008 was used as baseline and the 30-year follow-up in 2010-2012 as follow-up. NZANS was a cross-sectional survey and thus included in the cross-sectional analyses only. For QFS, phase 2 data acted as baseline and phase 3 data as follow-up, based on the quality of the dietary and physical activity assessment. Additionally, ca. 300 newly recruited participants in Phase 3 were included in the cross-sectional analyses.

Data in the PREVIEW study have been collected within the framework of independent population studies, with different protocols for data collection and distinct original research foci. Therefore, data harmonization was a major task of the study. Harmonized variables were created for all parameters of interest for the PREVIEW data-analysis.

Baseline dietary intake, in particular protein intake and glycemic index and glycemic load, physical activity data, and sleep duration will be related to the prevalence and incidence of pre-diabetes, diabetes, and levels of fasting plasma glucose or HbA1c.

Results and Publications

Intention to publish date30/10/2017
Individual participant data (IPD) Intention to shareNo
IPD sharing plan summaryNot expected to be made available
Publication and dissemination planMain results will be published in peer-reviewed journals and presented at scientific conferences or symposia.
IPD sharing planAs the ‘PREVIEW Population studies’ makes use of existing data from different cohort studies the participant level data will be the property of and stored at the local study sites. Moreover, recruitment and analyses will continue for some cohort studies outside the scope of the ‘PREVIEW Population studies’ and so data cannot be made publicly available right now.
