Final answer:
Sam has three major risk factors for type 2 diabetes: obesity, a family history of diabetes, and belonging to a demographic group with a higher prevalence of obesity.
Step-by-step explanation:
Sam, the individual in question, is recognized to have three of the major risk factors for type 2 diabetes. These include being obese, having a family history of diabetes, and being part of a demographic group that is more likely to have obesity, which in his case is African-American male. It is critical to acknowledge that obesity is a significant predictor of type 2 diabetes, influencing insulin resistance and potentially leading to the condition if paired with other risk factors, such as genetic predisposition, represented here by a family history of the disease.
Type 2 diabetes can be influenced by lifestyle factors, and in Sam's case, obesity and family history are clear risk factors. Lifestyle changes including weight management, healthy eating habits, and regular physical activity can help manage or even reverse type 2 diabetes in some cases.
