| | Chicago Healthy Aging Study (CHAS) |  | | | Following-up formerly participants of the Chicago Heart Association Study (CHA) (baseline exam 1967-73) ages 65-84 in 2007-10, the Chicago Healthy Aging Study (CHAS) is aimed to demonstrate that, after 40 years of follow-up, compared to those not-low-risk (LR), persons LR at younger ages experience healthier aging in terms physical functioning, disease diagnoses, and comorbidities. Low-risk is defined as having favorable levels of all readily measurable major cardiovascular risk factors. | Under the direction of Dr. Martha L. Daviglus, Professor of Preventive Medicine, and her team, the study is recruiting 1,500 former CHA participants to attend a clinical examination to obtain current CVD risk factor data, non-invasively measure coronary artery calcium (an indicator of CHD/CVD), and assess healthy aging using a variety of performance based measures of physical functioning. Six hundred formerly LR participants and nine hundred formerly not-LR participants will be recruited. Medical conditions reported by participants on their medical history questionnaires will be verified and supplemented using Medicare billing data from the Centers for Medicare and Medicaid Services (CMS). The study is funded by a $2.9 million, 4 years grant from the National Institutes of Health (NIH).
Given that persons age 65 and older comprise approximately 13% of the U.S. population, but account for an estimated 33% of the nation’s health care expenditures and by the year 2030, older individuals will constitute 20 to 25% of the U.S. population, the results for this study may have important implications for public health policy and allocation of resources for CVD and non-CVD prevention for controlling risk factors starting early in life. |
