Study details

S.O.C.A. is a cross-sectional study of age-related differences in cognitive function in middle age and older adult African Americans. The study aims to address the following research questions:

1) Do cardiovascular risk factors such as hypertension and obesity influence cognitive abilities such as memory and processing speed?
2) Do psychosocial influences such as depression and discrimination have a negative influence on cognitive function?
3) Do psychosocial influences such as social support and mindfulness have a protective role in cognitive function?
4) Are psychosocial factors predictive of blood pressure and weight outcomes?
