Diabetes and psychological co-morbidity in children with a family history of early-onset type 2 diabetes.

The present study was conducted to evaluate for depressive symptoms and undiagnosed diabetes in children with familial history of early-onset type 2 diabetes. Studies have shown that diabetes doubles the risk for depression and that the duration of diabetes is related to the severity of the depression. Individuals with depression are also said to be at greater risk for developing diabetes. In many cases diabetes is detected whilst screening for depression. Fifty-three children aged between 6 and 17 years were screened for diabetes and assessed for depressive symptoms using the Children Depression Rating Scale, revised version (CDRS-R). Thirty-six (68.0 %) of the children with a family history of early-onset type 2 diabetes had CDRS-R scores consistent with likely or very likely major depressive disorders. Depressive symptoms score was predicted best by the number of generations of diabetes in the family, with an associated r = .65 and adjusted R(2) = .41. As the generations of diabetes increased, the more likely it was for a child to have diabetes (r = .38, p = .005). Four (7.5%) of the children were diagnosed with diabetes. The findings suggest that depressive symptoms are common in children with a family history of early onset type 2 diabetes and may co-exist with diabetes. The independent variable that reliably predicted the child depressive symptoms score was the number of generations of diabetes in the family.
