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. The DEDIPAC KH is a multidisciplinary consortium of scientists from 46 research centres in 12 countries across Europe.

The work in DEDIPAC is divided into three Thematic Areas (TAs):

TA 1: Assessment and harmonisation of methods for future research, surveillance and monitoring, and evaluation of interventions and policies

TA 2: Determinants of dietary, physical activity and sedentary behaviours across the life course and in vulnerable groups

TA 3: Evaluation and benchmarking of public health and policy interventions aimed at improving dietary, physical activity and sedentary behaviours

Our work is part of TA 1 of which prof. Pieter van ‘t Veer is thematic area leader. We contribute to two specific tasks:

Task 1.1.2: Describe the variation in dietary intake and dietary behaviour by demographic variables across Europe.

Here we will focus on sugar-sweetened beverage (SSB) intake in the NQplus study. We plan to compare frequencies of intake based on repeated 24-hour recalls and FFQ. Also, we will identify demographic determinants of intake and assess whether these are similarly important between the two methods. Finally, we will identify SSB consumption patterns and explore whether determinants of SSB intake differ between people with different patterns.

Task 1.1.3: Develop an innovative integrated method to assess dietary intake, dietary behaviour, physical activity, sedentary behaviour and their determinants for application in future.

We contribute to the development and feasibility pilot of the DEDIPAC innovative integrated smartphone-based assessment method to concurrently assess diet, physical activity, and their determinants. The pilot study will take place in Germany, Norway and the Netherlands in the second half of 2015. We will include at least 20 students (m/f) from Wageningen University who will use the innovative method for one week.
