Lower IQ is associated with an increased risk of mortality and morbidity. One suggested explanation is that persons with lower IQ more often have behavioral risk factors. In this seminar, data on the association between IQ and smoking among young men is presented and discussed.

Tomas Hemmingsson has recently joined SoRAD and the Stockholm University to work as a Professor in social research on alcohol and drugs. Tomas had previously worked at the Department of Environmental Medicine at the Karolinska Institutet and his research interest has been mainly focused on associations between work and labour market related exposures and later health outcomes, e.g. alcoholism, all-cause mortality, coronary heart disease, stroke, suicide, and disability pension. Another important area of research has been to estimate how social and psychosocial factors measured in early life, before or at time of labour market entry, may have an impact on later health and social achievement, and to what extent such factors, by themselves or in combination with other factors (e.g. behavioral factors and psychosocial stress), may contribute to produce health differences between socioeconomic groups, occupations, educational groups, and persons with different psychosocial work environments. Mental health and cognitive ability have always been among the central themes in Tomas’s research on early life factors and later disease.
