Abstract: Objective To investigate the quality of life of elderly diabetic patients and its influencing factors. Methods By
randomized cluster sampling, we conducted a survey in 1450 elderly residents (over 60 years old) living in urban, suburban
and rural areas in south and north Anhui province. We evaluated the quality of life of the elderly diabetic patients using a
demographic information questionnaire and full items on Short Form (36) Health Survey (SF-36). Results The elderly diabetic
patients had lower scores in all dimensions of quality of life than the elderly without diabetes. Multiple linear regression
analysis showed a linear regression in the quality of life among the elderly diabetic patients in terms of geographic regions,
education, personality, sleep quality, and age. Conclusion Elderly diabetic patients have generally poor quality of life, which
was subjected to the influences by geographic regions, education, personality, sleep quality, and age, suggesting the necessity
of corresponding interventions to improve the quality of life of these patients.
