This project has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no In Brief Health Impact Model Background Conceptual Framework 4-year project in 7 European cities Key objectives: Improving our understanding of active transportation behavior, its relationship to physical activity, and associated risks Translating these findings into improved health impact modeling Physical Activity through Sustainable Transport Approaches (PASTA) a pan-European project on determinants and impacts of active transportation The promotion of active transportation (AT), i.e. walking and bicycling for day-to-day travel, is a promising approach to increase overall physical activity (PA). Health impact models (HIM) show substantial net benefits of AT. However, a number of uncertainties affect these models. PASTA Survey The core study is designed as a longitudinal web-based survey which consists of a substantial baseline questionnaire (30min) and bi-weekly short follow-ups (5min). Every 3 rd FU-Q is somewhat longer (10min). Baseline and long FUQ assess travel and PA behavior through a 1-day travel diary and an adapted version of the global physical activity questionnaire (GPAQ).

It brings together perspectives from transport planning, travel behavior and health research as well as policy and practice. Within the project a cohort study across seven European cities is investigating (a)the key determinants of AT behavior (b)how AT relates to PA (c)effectiveness of measures to promote AT A main aim of this empirical study is to contribute to the improvement of HIM of AT. A comprehensive conceptual framework was developed building on previously published frameworks and underlying theories. The framework ingrates aspects relevant to both AT and PA behavior, distinguishes data hierarchies and guides PASTA survey contents, data collection and analysis. Your text goes here.

A recruitment monitoring dashboard is used to track progress and target recruitment to reach a balanced sample. The goal is to recruit at least 2000 participants in each of the seven cities (so far 3500). Subsamples are invited to participate in add-on modules using objective measurements of trips, activity and air pollution.

Previously published HIM have been reviewed systematically (Mueller N. et al. forthcoming. Presentation Tuesday 10:30AM). The survey will provide insights in AT/PA substitution and produce exposure adjusted crash rates for minor crashes. Selected elements of the PASTA HIM will be fed into the further development of WHO‘s Health Economic Assessment Tools for walking and cycling (HEAT) (Workshop Tuesday 10:30AM).
