Photo-based dietary assessment tools There is a growing number of dietary assessment tools. More and more classical approaches are digitalized and available as online tools or mobile apps. With smart phones as permanent companion through everyday life, photo-based dietary assessment becomes increasingly important. The aim of this project is to compile a market overview of photo-based dietary assessment tools and evaluate the strengths and limitations of such approaches.
Integration of Behaviour Change Techniques within nutrition-related mobile apps The number of mobile apps exploded within the last years. Putting the quantify-yourself movement into focus, especially apps focusing on health outcomes are booming. Yet, most of these apps are used rather at short term. Keeping users motivated to use the apps on a long term, some apps integrate behavioural change techniques like goal setting and monitoring within their features. The aim of this project is to perform a literature research and content analysis focusing on the integration of behavioural change techniques into nutrition related apps.
Trends in energy intakes over the previous decades Researchers claim that the current obesity pandemic has been caused by increasing energy intakes in many populations over the previous decades. But representative and reliable data are scarce, and the comparability of results from respective epidemiological studies is limited. The aim of this project is to perform a literature research and some kind of meta analysis in order to shed light into the issue of (global) trends in energy intakes.
Comparison of the nutritional situation in EC Member States based on FAO's Food Balance Sheets Worldwide dietary data for nutrition monitoring and surveillance are commonly derived from food balance sheets (FBS), which provide valuable yearly information on food availability on a national level. Therefore, these data are well suitable for comparisons either across countries or over time, or even both. The aim of this project is to compare the nutritional situation in EC member states and respective time trends since the year 2000.
