Abstract
Background
Among people with diabetes, depression is more common and is associated with greater morbidity and mortality. A better understanding
of mechanisms underlying the link between poor health and depression is needed. Pain and functional impairment may account
for the effect of poor health on depression in diabetes.
of mechanisms underlying the link between poor health and depression is needed. Pain and functional impairment may account
for the effect of poor health on depression in diabetes.
Method
Adults diagnosed with type 2 diabetes (N = 77) completed the following measures: Patient Health Questionnaire (PHQ), Diabetes Symptom Checklist (DSC), and Medical
Outcomes Study 12-item Short-Form Health Survey (SF-12). Body mass index (BMI) was computed using height and weight data from
medical records. Mediation and linear regression analyses were conducted.

Conclusion
Pain and functional impairment appear to play important, independent roles in depression in type 2 diabetes. Mediation analyses
suggest the following: 1. diabetes-related medical problems increase functional impairment, which in turn leads to greater
depression; and 2. the burden of carrying greater body mass (higher BMI) increases pain, which leads to increased depression.
