Factors predicting sleep disruption in Type II diabetes.

This study investigated four correlates of diabetes as potential predictors of sleep disruption in people with Type II diabetes. A tentative causal model proposed obesity would lead to more severe diabetes, which would result in increased physical complications, which might in turn affect emotional adjustment, and all of these might combine to cause sleep disruption. It was found that within a diabetic sample, severity of diabetes was related to sleep disruption. Path analysis indicated that the relationship between Type II diabetes and sleep disruption was mediated by physical complications of the disease (pain and nocturia), and not by either obesity or emotional adjustment.
