ABSTRACT

Purpose

Evaluate the prevalence and risk factors of depression in diabetic retinopathy (DR). Compare subjective and objective measures of visual function predictivity of depression.

Methods

National Health and Nutrition Examination Survey 2005–2008 participants aged ≥40 who underwent fundus photography, Patient Health Questionnaire (PHQ)-9, and Visual Function Questionnaire (VFQ-25) were included in the study. Multivariable logistic regression was used to evaluate whether DR was a significant risk factor for depression and to evaluate the risk factors for depression in those with DR.

Results

A total of 5704 participants, 47% male, and mean age 56.5 years were included in this study. Persons with moderate, severe non-proliferative diabetic retinopathy (NPDR), or proliferative retinopathy (PDR) had higher prevalence of depression than participants with mild retinopathy or no retinopathy (14.3%, 6.9%, 7.0%). Moderate-to-severe NPDR or PDR (OR: 2.36, p = .04) was associated with depression. Among persons with DR, best-corrected visual acuity and HbA1c were not associated with depression. However, self-reported measures of vision were associated with depression: some of the time spent worrying about eyesight (OR: 4.59, p = .010), vision limit activities some of the time (OR: 8.52, p < .001), vision limits activities most/all of the time (OR: 6.99, p < .001).

Conclusions

A significant proportion of patients with DR in the NHANES population had co-morbid major depression. Best corrected visual acuity was not associated with depression in those with DR, while subjective, self-reported measures were associated with depression, suggesting subjective measures are a better determinant of poor mood and low functional status.
