OBJECTIVE: To evaluate the self-reported quality of life in individuals
with diabetes of long duration. RESEARCH DESIGN AND METHODS: An interview
was administered 14 years after baseline to two cohorts of individuals with
diabetes who have been followed in an epidemiological study periodically
since 1980. Responses to the Medical Outcomes Study Short Form 36 as
related to complications of diabetes, age, glycosylated hemoglobin level,
and other characteristics were assessed. RESULTS: Physical function,
physical role, general health scales, and a general question about health
were related to diabetes characteristics in older- and younger-onset
individuals. Symptoms of sensory neuropathy were associated with the four
measures in both younger- (n = 645) and older-onset (n = 292) individuals.
Other descriptive variables in the younger-onset group were the presence of
nephropathy, cardiovascular disease, smoking, peak expiratory flow,
physical activity, and glycosylated hemoglobin. Hypoglycemic reactions were
of only borderline significance and that for only one scale (physical
role). In older-onset individuals, cardiovascular disease, physical
activity, and sex were descriptive of responses to the quality-of-life
questions. CONCLUSIONS: Factors related to diabetes contribute to
self-assessed health. some of these factors may be modifiable, which, if
altered, may lead to improved quality of life.
