Susanna ToivanenPresentation at ENSP/FiocruzAug 21st, 2013
Current research topics include
• working life and health among the self-employed
• foreign born persons' working conditions and health in
Sweden
• future workplaces (offices), working life and health
• social determinants of health and health inequalities in
working populations
• gender and health
Social Inequalities in Health
“Inequalities in health are systematic differences in health
between different socio-economic groups within a society.
As they are socially produced, they are potentially avoidable
and widely considered unacceptable in a civilized society.”
Margaret Whitehead, 2007

Social Determinants of Health
“The circumstances in which people grow, live, work, and age, and the systems put in place to deal with illness.
The conditions in which people live and die are, in turn, shaped by political, social, and economic forces”.

WHO Commission on Social Determinants of Health
“Reducing health inequities is an ethical imperative.
Social injustice is killing people on a grand scale”.

Gender discrimination in the labour market - Obesity, Unemployment, and Earnings
• Effects of obesity (BMI≥30) on unemployment• Obese women had a significantly higher risk of
unemployment than not obese women• Obese women’s weaker labour market attachment
translated to lower earnings • Similar results were not found among men
