The social class variable may be the educational level, or a professional classification. Different aspects of mortality and morbidity are examined: cancer, cardio-vascular diseases, respiratory diseases, musculo-skeletal diseases, digestive diseases, obesity and diabetes, accidents, mental illnesses; acute and minor illnesses, and unusual illnesses, are no studied. For almost all the diseases in this review, the risk is greater in the lowest socioeconomic class.
