Quality of life in a US national sample of adults with diabetes and motility-related upper gastrointestinal symptoms.

Our objective was to describe the health-related quality of life (HRQoL) of individuals with diabetes with and without motility-related upper gastrointestinal symptoms compared to individuals without diabetes. A total of 483 individuals with diabetes and 422 age- and gender-matched nondiabetic controls were recruited from a prior US national health survey for a telephone interview on upper gastrointestinal symptoms. Individuals with diabetes self-reported a physician's diagnosis of diabetes and provided confirming information on clinical management measures. Subjects were asked about upper gastrointestinal symptoms in the month before interview using an instrument with demonstrated high reliability. HRQoL was measured using the SF-12 Health Survey. Individuals with diabetes reporting upper gastrointestinal symptoms scored significantly lower in HRQoL measures of physical health and mental health than either individuals with diabetes who did not report upper gastrointestinal symptoms or individuals without diabetes (P < 0.0001). Individuals with diabetes and no upper gastrointestinal symptoms had physical and mental health summary scores similar to those of individuals without diabetes. Early satiety was the strongest predictor (P < 0.0001) of differences in physical health scores between individuals with and without diabetes. Nausea was the strongest predictor (P < 0.0001) of differences in mental health scores between individuals with and without diabetes. In conclusion, this is the first US national survey to demonstrate that motility-related upper gastrointestinal symptoms are associated with a significantly lower quality of life in individuals with diabetes.
