Abstract
The objective of the paper is to evaluate the performance of the American Diabetes Association
Questionnaire for the risk/diagnosis of diabetes among subjects with systemic hypertension.
Between January and May 2004, screening for type 2 diabetes was conducted among people known to have, systemic hypertension and who were regular attendees of Cardiology and Nephrology clinic of the Lagos University Teaching Hospital. Screening was done using the American Diabetes Association Questionnaire (ADAQ): take the test known the risk. Oral glucose tolerance test was carried out on all the subjects as the standard for the diagnosis of diabetes. Subjects were classified based on their total score on the ADAQ into- No Risk (where score was 0-2), High Risk (where score was 5-9) and diabetes when score was >10.
Resalts: A total of 207 patients were recruited of whom l3lcompleted the study, giving a participation rate of 63.28 percent. Over thirty percent (30.53%) of the 131 subjects who completed the study were at high risk for diabetes while 69.46% were classified as Diabetes (>10) based on ADAQ. ADAQ yielded a sensitivity of 79.16%, a specificity of 32.71% a positive predictive value of 20.88% a negative predictive value of 87.5% and an efficiency of 41.22%. r = 0.04, y = 156.89+1.4 ADAQ with p value not significant (P value > 0.05)
Conclusion: The ADAQ performed poorly in our cohort of patients with systemic hypertension. Modification will need to be made to the ADAQ to enhance its performance in our study population.
