Although it is now well established that socioeconomic inequalities in health and mortality prevail into very old age, the patterns and etiologies of these health inequalities are still largely unexplored. In recent studies based on population data from Sweden and Finland, we have shown that education is significantly associated with physical and cognitive functioning as well as with rheumatoid arthritis. Individuals with lower education are more likely to have all of these conditions than individuals with a higher education1,2. Health inequalities during old age are likely shaped by lifelong processes. Thus, in order to understand these inequalities, it is necessary to apply a life-course perspective. Using datasets comprising longitudinal survey and registry data, we have explored the association between socioeconomic conditions during different stages of the life course and mortality. The results showed that social class in childhood and adulthood were both independently associated with premature mortality (i.e., before the age of 70)3. Similarly, income in midlife and income during retirement were both independently associated with mortality during retirement4. The mechanisms generating late-life health inequalities are opaque. However, in a new study we have shown that socioeconomic differences in smoking and obesity could partly explain the socioeconomic inequalities in mobility and cognitive impairments observed among elderly Swedes5. Yet another study found that older individuals with higher education were more likely to participate in health-enhancing exercise than individuals with lower education6.
