Association between the physical activity level and the quality of life of patients with type 2 diabetes mellitus.

[Purpose] Physical activity and regular exercise play an important role in glycemic control, which is considered an important part of the treatment of type 2 diabetes mellitus. This study evaluated physical activity level and its relationship with quality of life in patients with type 2 diabetes mellitus. [Subjects and Methods] We evaluated 129 subjects with type 2 diabetes mellitus through a face-to-face interview using the short version of the International Physical Activity Questionnaire and Diabetes-39. Demographic data, diabetes symptoms, time of initial diagnosis, and treatment procedure/approaches were recorded. [Results] Of the study subjects, 51 (39.5%) had low, 67 had moderate (51.9%), and 11 (8.5%) had high activity levels. The mean weekly sitting duration was 302 minutes. The mean weekly walking time was 231.7 minutes. Except for the "diabetes control" domain, scores for all the subgroups and the total score in the quality-of-life assessment had a statistically significant negative correlation with physical activity level. [Discussion] Physical inactivity negatively affects the quality of life of diabetic patients. A planned exercise education program and incorporation of exercise into the lifestyle can improve the quality of life of patients with type 2 diabetes mellitus.
