The Determinants of Diet and Physical Activity (DEDIPAC) Knowledge Hub (KH).
DEDIPAC KH is the first a joint action of the Joint Programming Initiative A Healthy Diet for a Healthy Life (JPI HDHL).
The main objective of DEDIPAC is to understand the determinants of dietary, physical activity and sedentary behaviours and to translate this knowledge into a more effective promotion of a healthy diet and physical activity.
Professor Lien is leading thematic area 2: Determinants of dietary, physical activity and sedentary behaviours across the life course and in vulnerable groups. The overall objective of TA 2 is to provide the Pan-European research community with trans-disciplinary frameworks of determinants of dietary physical activity, sedentary behaviours and social inequalities, including best-practice methods to analyse data based on such frameworks and identification of gaps in current research.

Early promotion of healthy dietary habits: Targeting kindergarten and home environments in a three-armed intervention study.
The overall objective is to develop, implement and evaluate a theory and evidence-based intervention targeting vegetable consumption of 3-5 year olds through environmental changes in the kindergarten and the home in a three-armed, group-randomized controlled study design.
The study has been named “BRA-studien” and will be conducted in 90 kindergartens in Vestfold in 2015-2017. There will be 30 kindergartens receiving the intervention, another 30 kindergarten receiving the intervention plus a family component and there will be 30 kindergartens serving as controls.

Social inequalities in adolescents' dietary behaviours and changes over time
Through three longitudinal datasets from Oslo (age 15-18, UngHubro/Ung2004), Hordaland county (age 13-30, the Norwegain Longitudinal Health Behaviour Study) and Eastern Norway (age 12-13, The HEIA-study) we aim to understand which factors influence the development of dietary behaviours and weight and whether these differ by socio-economic status (SES). In the EU-funded TEENAGE project the aim was to reanalyse dietary intervention studies to investigate if the effect differed by SES.

Healthy weight development among adolescence
European prevalences of overweight/obesity and factors influencing weight development was studied in the HOPE-project, whereas the projects HEIA and ENERGY aims to change energy balance related behaviours of 11-12 year olds through school-based and family oriented strategies.

Promoting fruit and vegetables among school children
A series of comprehensive school-based intervention studies aimed at 11-12 year olds has been conducted since 2001 starting with the Norwegian project Frukt og grønt i 6! (Fruit and Vegetables Makes the Mark (FVMM)) followed by the European projects Pro Children and Pro Greens. In the Pro Children study computer tailoring to provide personalized advise was used with children for the first time and it has later been studied as a strategy on it's own.

A culturally adapted intervention study to prevent type 2 diabetes/metabolic syndrome among Pakistani immigrant women with main focus on nutrition
The study is based on experience from the project above. It is focussed on the chain of potential changes after a culturally adapted intervention, from food perceptions and perceptions of risk factors for diabetes, intentions to make dietary changes, barriers to do so, and actual dietary changes, to changes in blood glucose and other components of the metabolic syndrome.

The PREPARE project
The main purpose of this EU funded research project is to develop interventions which are effective in reducing the spread of sexually transmitted diseases (including HIV) and unwanted pregnancies by changing sexual- and reproductive behaviours among adolescents in selected sites in Sub-Saharan Africa.

The LASH (Limpopo - Arusha School Health)
Project aims at improving the evidence base for school-based adolescent health programs in Sub-Saharan African settings (South Africa and Tanzania). The project is the first attempt to do a group radomized trial to investigate the potential for a comprehensive, school-based program in improving the general health of adolescents.
