Dr. Mendes de Leon is a social epidemiologist with a primary interest in the major health problems and health disparities in late life. His work focuses on a broad array of social and psychological determinants that affect the development and progression of disability, cognitive decline and other common, age-related health outcomes. Specific areas of interest include the life-course social conditions and biological processes that affect physical and cognitive decline in older age, the role of work-related experiences in retirement timing and process and post-retirement health trajectories, and health disparities in African American and Arab American populations. He is also involved in several international collaborations, including in the Middle East, South-East Asia, and the Netherlands. He is an active member in professional organizations in the fields of gerontology, population health science, and epidemiology, and serves on the editorial board of several scientific journals in these disciplines
A sudden loss of wealth in middle or older age is not only devastating economically, but it can also have dire consequences for one’s health, and even be deadly. We investigated the question whether a large, sudden loss of wealth in middle or older age increases a person’s risk of dying. We focused the study on adults who were at least 51 years old when they experienced a sudden loss of wealth, since they have limited years remaining to regain this loss. We used data from almost 9,000 participants who were followed for up to 20 years after joining the study. Every two years, participants answered a series of questions on assets and debts that were used to calculate total wealth. About a quarter of participants experienced a negative wealth shock, and we found that this was associated with a 50% higher risk of dying compared to those who did not have such a loss of wealth. We further noted that the risk of dying among those with a negative wealth shock was almost as high as that of participants who did not have any wealth at all. The higher risk of death associated with the sudden loss of wealth did not depend on a person’s initial wealth; it was about the same among the wealthiest participants as it was among the less wealthy. Our findings offer new evidence for an important social determinant of health that so far has not been recognized: sudden loss of wealth in later middle or older age. They enrich our understanding of the critical role other social determinants such as low education, poverty, unemployment and housing instability in population health and health inequities.
