This thesis aims to examine the impact of certain demographic, economic and health-related characteristics on the body mass index (BMI) of European people aged fifty years or above. The analysis is based on data from the second wave of the Survey of Health, Ageing and Retirement in Europe (SHARE). To begin with, some basic information about the body mass index are cited (a review of the index and disadvantages), as well as some important information about the epidemic phenomenon of obesity, mainly focused on people aged fifty years or above and among countries (risk factors and health problems). Subsequently, the statistical processing and analysis of the data takes place which is structured in two parts. In the first part (Chapters 2 and 3) descriptive statistical methods are mainly used (frequency and contingency tables, graphs, tests of independence, contingency measures) while the second one (Chapter 4) contains the development of multinomial logistic regression models in order to investigate which exact factors affect weight and to what extent. The last chapter summarises the primary conclusions emerging by the analysis of the available data. A significant finding worth mentioning is the fact that the majority of the people in the sample are overweight whereas gender, country of residence as well as economic affluence are only some of the factors affecting weight.
