Importance of tangible physical changes for quality of life improvements of type 2 diabetic and at-risk individuals involved in exercise intervention a quasi-experimental design

Abstract FRE

Objectives: 1) To document quality of life (QOL) changes in type 2 diabetes (T2D) and at-risk individuals who took part in the DiabetAction program and 2) to determine if changes in the QOL were associated with program attendance.

Methods : QOL (SF-36 questionnaire), physical activity (PA) level, body weight, skinfold thickness, aerobic capacity and handgrip strength were measured before and after the 10-week intervention in 15 T2D and 14 at-risk individuals.

Results: Physical and mental components of QOL and 6 out of 8 domains of QOL were significantly improved in T2D and at-risk individuals after the intervention.

Four significant correlations were identified: physical functioning domain with skinfolds (r = – 0.56) and aerobic capacity (r = 0.49), social functioning domain with handgrip strength (r = 0.43) and the physical health summary measure with body weight (r = – 0.45).

Conclusion : QOL was significantly improved after the DiabetAction program.

Also, PA intervention appears to impact QOL to a larger extent when participants experience changes in body composition and fitness.
