Topical review: a comprehensive risk model for disordered eating in youth with type 1 diabetes

J Pediatr Psychol. 2015 May;40(4):385-90. doi: 10.1093/jpepsy/jsu106. Epub 2014 Dec 10.


Objectives: Provide an updated literature review on prevalence, measurement, and correlates of disordered eating in youth with Type 1 diabetes (T1D), present a novel theoretical risk model (i.e., The Modified Dual Pathway Model) for disordered eating in youth with T1D incorporating psychosocial and physiological risk factors, and discuss clinical implications.

Methods: Literature review of prevalence, correlates, risk factors, and outcomes of disordered eating behavior (DEB) in youth with T1D.

Results: Insulin treatment, subsequent weight gain, and disruptions to hunger and satiety regulation are hypothesized disease-related mechanisms through which the treatment of T1D may increase vulnerability to development of behavior characterized as DEB. The Modified Dual Pathway Model integrates these factors with a validated psychosocial risk (body dissatisfaction, depression, and abstinence violation) model for DEB in nondiabetic youth.

Conclusions: The Modified Dual Pathway model of DEB in youth with T1D is a comprehensive representation of both psychosocial and T1D-related risk factors with the potential to inform future interventions for this population.

Keywords: Modified Dual Pathway; Type 1 diabetes; eating disorders; risk for disordered eating in T1D.
