Final answer:
Older African-Americans experience a higher incidence of Type 2 diabetes and Cardiovascular disease, with contributing factors such as obesity, poor diet, and inactivity leading to metabolic syndrome, which increases these health risks.
Step-by-step explanation:
Among the health issues observed at an above-average rate in older African-Americans, Type 2 diabetes and Cardiovascular disease are notably prevalent. African Americans have a higher incidence of several diseases, including Type 2 diabetes, which is often associated with obesity. This demographic group has been found to have higher rates of obesity and eating disorders compared to other ethnic groups. Contributing factors to these health disparities include behaviors such as smoking, unhealthy diet, and physical inactivity, all of which are risk factors that potentially lead to metabolic syndrome, a major risk factor for cardiovascular diseases and Type 2 diabetes.
