Socio-professional level and long-term mortality in three Belgian large-scale studies

Introduction: Psychosocial factors have been evidenced worldwide to influence mortality. But there are less studies that have shown longterm prediction of these psychosocial dimensions. Comprehensive multidimensional models (1) have been conceptualised and tested for health inequalities, mortality and morbidity but seldom for long-term mortality. Methods: Data from three Belgian large-scale studies were analysed, namely the “Belgian Heart Disease Prevention Project” (BHDPP), which started in 1972, the “Physical Fitness Study” (PFS) in 1977 and the “Belgian Interuniversity Research on Nutrition and Health” (BIRNH) which started in 1982 but was restricted to working males aged between 3559 years old.
