Background: Overweight Hispanic women are at high risk for type 2 diabetes. A clinical diagnosis of hyperglycemia is often necessary to access interventions. We examined the prevalence of undiagnosed hyperglycemia among a group of low-income overweight or obese Hispanic women, who were receiving care at a Federally Qualified Health Center (FQHC). Methods: Among 196 overweight or obese Hispanic women (mean age 44 ± 10 years, mean weight 86.8 ± 16.5 kg, mean body mass index [BMI] 36.5 ± 6.4 kg/m 2 ) enrolled in a randomized clinical weight-loss trial, we compared A1C and fasting blood glucose (FBG) obtained at baseline with women’s existing diabetes and prediabetes diagnoses in the medical record. Results: According to the information in participants’ medical records, 36% (70/196) had diagnosed diabetes, 20% (39/196) had a diagnosis of prediabetes, and the remaining 44% (87/196) had neither diagnosis. Among participants without a diagnosis of diabetes or prediabetes during the baseline screening for our study, 63% (55/87) had at least one test in the prediabetes range (baseline A1C and FBG were in prediabetes range for 39 and 55 participants, respectively), and 13% (11/87) had at least one test in the diabetic range (baseline A1C and FBG values in diabetes range for 3 and 11 participants, respectively). Discussion: We found substantial prevalence of undiagnosed hyperglycemia among a sample of overweight and obese Hispanic women. It is possible that limited awareness of diabetes risk may be a barrier to patient compliance with screening recommendations.
