Abstract

Objective:

To investigate which features of eating disorders are associated with retinopathy and nephropathy in Type 1 diabetic females with clinical eating disorders.

Method:

Participants were 109 Type 1 diabetic females with clinical eating disorders diagnosed by the structured clinical interview for DSM-IV (bulimia nervosa [n = 70], binge-eating disorder [n = 28], anorexia nervosa [n = 7], and eating disorder not otherwise specified [n = 4]). Retinopathy and nephropathy were screened and demographic, medical, and eating disorder related factors were investigated. To identify the factors associated with each complication, logistic regression analysis was done.

Results:

Duration of severe insulin omission and duration of Type 1 diabetes were significantly associated with retinopathy (odds ratios = 1.35 and 1.23, respectively) and nephropathy (odds ratio = 1.35 and 1.21, respectively) in multivariate regression analyses.

Conclusion:

Of the various problematic behavioral factors related to eating disorders, the duration of severe insulin omission was the factor most closely associated with the retinopathy and nephropathy of Type 1 diabetic females with clinical eating disorders by multivariate analysis. This finding may help patients who deliberately omit insulin become aware of medical risk of insulin omission. © 2007 by Wiley Periodicals, Inc. Int J Eat Disord, 2008
