Mortality in Europe in 2015: the effects of optimistic attitude
This thesis aims to investigate factors related to mortality; a crucial point to assess is the impact of optimism and positive attitude. In the 1st chapter, the definition of mortality is provided and further analyzed through listing the main causes of death and the relevant risk factors. At the same time, the concept of optimism and ways to measure it are presented. In the next chapters, data from the 5th and the 6th wave of the Survey of Health, Ageing and Retirement in Europe is used in order to perform statistical analysis. More specifically, in the 2nd chapter, descriptive analysis of the most important variables included in the database is carried out as a first approach. Subsequently, in the 3rd chapter the findings of bivariate analysis, performed through use of descriptive statistical methods, are presented. In particular, graphs, frequency tables, test of independence and contingency measures are used. Furthermore, in the 4th chapter logistic regression models are developed in order to investigate the effect of sociodemographic variables, behavioral risk factors, morbidity and optimism on mortality. To conclude, in the 5th chapter the main conclusions extracted through data analysis are summarized. In fact, it is worth noting that the effect of demographic factors such as gender, age, country of residence and factors regarding morbidity has been confirmed. To sum up, it should be emphasized that optimism, happiness and life satisfaction play a pivotal role in reducing the probability of dying.
