In general, the study found that the prevalence of adult and pediatric type 1 diabetes was significantly lower in most black neighborhoods, while the prevalence of adult type 1 diabetes was significantly lower in most Hispanic neighborhoods. Higher-income neighborhoods showed a significantly higher prevalence of pediatric type 1 diabetes.
The prevalence of type 2 diabetes in adults was significantly higher in low-income neighborhoods and those with more elderly residents, while the highest rates of pediatric type 2 diabetes were found in black neighborhoods.
The authors commented that they were surprised that their data did not show a higher prevalence of adult type 2 diabetes in black neighborhoods.
“In our multivariate analysis, older age and lower income were the only demographic or socioeconomic factors associated with higher adult type 2 diabetes prevalence,” they wrote.
