She directs the Southeastern San Diego Cardiac Disparities Project, which aims to reduce
the incidence of heart disease among African - Americans, who are at greater risk for developing the disease, according to the American Heart Association.
As in prior studies
among older adults, we found that obesity was associated with a decreased risk
of dementia, consistent with the hypothesis that, while obesity in mid-life may increase risk for later - life cognitive decline and dementia, obesity at older ages may be associated with cognitive and other health advantages.25 - 27 The trend toward a declining risk for dementia in the face
of a large increase in the prevalence
of diabetes suggests that improvements in treatments between 2000 and 2012 may have decreased dementia risk, along with the documented declines in the
incidence of common diabetes - related complications, such as
heart attack, stroke, and amputations.11 Our finding
of a significant decline between 2000 and 2012
of the
heart disease - related OR for dementia would also be consistent with improved cardiovascular treatments leading to a decline in dementia risk.
