Awareness of Prediabetes and Diabetes among Persons with Clinical Depression

Abstract EN

Background.

Major depressive disorder (MDD) is highly comorbid with diabetes, a relationship underappreciated by clinicians.

Purpose.

Examine the proportion of nonpregnant individuals ≥20 years with MDD and elevated glucose and the demographic and clinical characteristics associated with unrecognized elevated glucose.

Methods.

14,373 subjects who participated in the National Health and Nutrition Examination Survey (2007–2012) completed the PHQ-9 depression screen and had hemoglobin A1C (HbA1c) measured.

PHQ-9 scores ≥10 and HbA1c scores ≥5.7% were defined as MDD and elevated HbA1c, respectively.

Data were analyzed using complex survey sampling software.

Results.

38.4% of the sample with MDD had elevated HbA1c readings.

Compared with nondepressed subjects, they were significantly more likely to have elevated glucose readings ( P = 0.003 ) and to be aware of their elevated glucose levels if they had a higher body mass index, family history of diabetes, more doctor visits in the past year, a usual care source, health insurance, or were taking hypertension or hypercholesterolemia medications.

Conclusions.

Many adults with MDD have elevated HbA1c levels, have never been advised of elevated HbA1c, have not received diabetes screening, and have minimal contact with a healthcare provider.

Additional opportunities for diabetes risk screening in people with MDD are needed.
