PhD thesis summary

PhD thesis title: “Development of causal models in investigating the relationship of social, psychological and nutritional parameters to the incidence of cardiovascular disease. 10-year follow-up of the ATTICA study (2002-2012)”

The aim of the doctoral dissertation is to investigate the relationship between social, psychological, behavioral and nutritional parameters in the 10-year incidence of cardiovascular disease in the ATTIKA study (2002-2012). As socio-economic factors, education and financial status are studied and as behavioral factors, smoking, physical activity and, above all, the psychological profile (depression, feeling of hostility, anxiety, hypochondriasis, unreasonable beliefs). All above, in the light of the adopted nutritional habits. Additionally, data from the ELSA study (English Longitudinal Study of Aging) are also used in order to explore the association of social determinants with healthy aging and mortality.

Although the literature on the individual relationship between dietary factors and the development of cardiovascular disease is particularly rich including valuable studies, data are comparatively less for the relationship between psychological and socio-economic factors and cardiovascular disease. However, the mechanism of cross-correlation between diet, psychology and socio-economic status in cardiovascular disease development has not been fully elucidated. Moreover, the attribution of causal relationships in this field is characterized as «cloudy landscape» in contemporary research.
