Cardiovascular (CV) diseases are the first cause of death in the EU. Given the treatment costs and the high prevalence of risk factors (smoking, physical inactivity, diabetes and hypertension), they account for the largest social and economic burden amongst all diseases. ERC grantee Manuel Franco proposes to measure the food, physical activity, alcohol and tobacco environments of hundreds of neighbourhoods in Madrid, a city with similar historical and demographic profile as many other European cities, and to correlate the results with cardiovascular primary care health records.
