In this project we lay the scientific foundations of a health impact assessment (HIA) tool that will be readily applied to a wide variety of urban settings in Low or Middle Income Countries (LMICs) to estimate health impacts of transport choices.
Globally, transport is a major contributor to the determinants of population health. These impacts are at their starkest in LMICs with rapidly increasing urbanisation and motorisation. The burden of road traffic injuries (RTIs) is predicted to rise globally from the 9th to 7th leading cause of death. In India there are an estimated 200,000 deaths per year, while Africa has the highest per capita burden. Urban outdoor air pollution (AP) also poses a large burden, greatest in Asia. The contribution of road transport to AP concentrations varies considerably, both between and within countries, but even where the percentage is small impacts can be large. At the same time LMICs face a growing burden of chronic diseases associated with lack of physical activity (PA). For example around 30% of the adult population are inactive in Brazil.
TIGTHAT is funded by an MRC Global Challenge Foundation Award and runs from April 2017 to March 2019.
This study represents a sister study to METAHIT. In METAHIT we are investigating how far we can go with a setting with good data. In TIGTHAT we are laying the foundation for a globally applicable model that can cover settings with diverse and typically limited data.
