Hypothesis
Diabetes preventive care would be less frequently received by non-Hispanic blacks than by whites in Missouri.
Conclusion
Non-Hispanic blacks in Missouri receive adequate screening for diabetic complications but not for glycemic control.
Supporting Evidence
- Non-Hispanic blacks were less likely to report having had glycosylated hemoglobin testing.
- Non-Hispanic blacks were more likely to report having received foot examinations.
- There was no significant difference in the probability of dilated eye examinations between blacks and whites.
Takeaway
The study found that black people with diabetes in Missouri get their feet checked more often than white people, but they are less likely to have important blood tests done.
Methodology
Data from the Missouri Behavioral Risk Factor Surveillance System from 1994 to 2002 was analyzed, focusing on diabetes-related preventive care among 842 diagnosed individuals.
Potential Biases
Potential recall bias in self-reported data and underrepresentation of rural black residents.
Limitations
The study may not represent all black residents in Missouri, as it does not include those without telephones, and self-reported data may be subject to recall bias.
Participant Demographics
16% of the sample were non-Hispanic blacks, who were younger and had slightly less income than whites.
