Final answer:
Ethnic groups such as African Americans, Mexican Americans, and Native Americans have a higher incidence of diabetes. Hispanics and African Americans with type 2 diabetes have a higher propensity for ketoacidosis. Obesity is a major risk factor for type 2 diabetes, particularly in high-income countries like the United States.
Step-by-step explanation:
The question seeks information about which ethnic or cultural groups have a high incidence of diabetes. Data indicate that several ethnic minorities including African Americans, Mexican Americans, and Native Americans have higher rates of diabetes compared to White individuals.
Additionally, it has been observed that among those with type 2 diabetes, Hispanics, and African Americans are more likely to go into ketoacidosis if an insulin dose is missed. Obesity is a significant risk factor for type 2 diabetes, which affects 90% of all diabetes cases. High-income nations, such as the United States, also see a correlation between rising obesity rates and diseases like diabetes.
