Abstract:Despite several decades of decline, cardiovascular diseases are still the most common causes of death in Western societies. Sedentary living and high fat diets contribute to the prevalence of cardiovascular diseases. This paper analyses the trade-offs between lifestyle choices defined in terms of diet, physical activity, cost, and risk of cardiovascular disease that a representative sample of the population of Northern Ireland aged 40-65 are willing to make. Using computer assisted personal interviews, we survey 493 individuals at their homes using a Discrete Choice Experiment (DCE) questionnaire administered between February and July 2011 in Northern Ireland. Unlike most DCE studies for valuing public health programmes, this questionnaire uses a tailored exercise, based on the individuals' baseline choices. A "fat screener" module in the questionnaire links personal cardiovascular disease risk to each specific choice set in terms of dietary constituents. Individuals are informed about their real status quo risk of a fatal cardiovascular event, based on an initial set of health questions. Thus, actual risks, real diet and exercise choices are the elements that constitute the choice task. Our results show that our respondents are willing to pay for reducing mortality risk and, more importantly, are willing to change physical exercise and dietary behaviours. In particular, we find that to improve their lifestyles, overweight and obese people would be more likely to do more physical activity than to change their diets. Therefore, public policies aimed to target obesity and its related illnesses in Northern Ireland should invest public money in promoting physical activity rather than healthier diets.

Abstract:Health Locus of Control (HLC) classifies our beliefs about the connection between our actions and health outcomes (Skinner, 1996) into three categories: "internal control", corresponding to health being the result of an individual's effort and habits; "control by powerful others", whereby health depends on others, such as doctors; and "chance control", according to which health depends on fate and chance. Using Choice Experiments we investigate the relationship between HLC and willingness to change lifestyle, in terms of eating habits, physical activity and associated cardiovascular disease risk, in a 384 person sample representative of the 40-65 aged population of Northern Ireland administered between February and July 2011. Using latent class analysis we identify three discrete classes of people based on their HLC: the first class is sceptical about their capacity to control their health and certain unhealthy habits. Despite being unsatisfied with their situation, they are reluctant to accept behaviour changes. The second is a group of individuals unhappy with their current situation but willing to change through exercise and diet. Finally, a group of healthy optimists is identified, who are satisfied with their current situation but happy to take more physical activity and improve their diet. Our findings show that any policy designed to modify people's health related behaviour should consider the needs of this sceptical class which represents a considerable proportion of the population in the region.

3. Increasing the acceptability of a congestion charging scheme

Abstract:Congestion charging is currently being considered as an important public policy in an increasing number of cities around the world, but evidence shows the importance of gaining public acceptability prior to its implementation. We analyse which factors should be considered to increase acceptability in the case of the Spanish city of Las Palmas de Gran Canaria. We applied a three-stage methodology: first a qualitative survey using focus groups, second Likert scales and exploratory factor analysis on a sample of 89 individuals, and finally, a stated choice (SC) experiment to a different sample of 206 respondents to value their preferences. The SC experiment was designed as a cordon-price scheme, including system features and considering three different uses for revenues: improving the current bus transport system, creating an underground line and increasing green areas in the city. Our qualitative analysis shows the previous resistance to accept any charging system, the lack of confidence on politicians and stresses the importance given to the use of revenues. On the other hand, values obtained from the SC experiment suggest that that public acceptability relies on the characteristics of the congestion charging scheme. In particular more than one third of the population would be willing to pay a daily fare of 2.22 if revenues from the system were used to increase the size of green areas instead of reinvesting this into the transport system.
