Correlation between lower-extremity functional status and obesity in type-II diabetic patients with and without peripheral arterial disease at Dr. Sardjito Central General Hospital, Yogyakarta

Abstract

Aim: To recognize the correlation between lower-extremity functional status and obesity in patients with type-2 DM with PAD complication (with and without peripheral arterial disease).

Methods: the study was a cross-sectional study conducted at Outpatients Clinic of Internal Medicine, Dr. Sardjito Central General Hospital in August-December 2006. Fifty-five subjects who were patients with type-2 DM aged more than 50 years agreed to participate and were eligible for the study; while the exclusion criteria included smoking, diabetic ulcer or gangrene, history of amputation due to diabetic ulcer or gangrene. The diagnosis of PAD was based on Ankle Brachial Index < 0.90.

Results: mean age was 62.53 +/- 6.82 years old and mean value of BMI was 24.26 +/- 3.57 kg/m2, 18 subjects (32.7%) were obese. The proportion of obese subjects with PAD was higher compared to the non-obese subjects (41% vs. 27%, p = 0.372). Lower-extremity functional status of type-2 diabetic patients either with or without PAD in obese subjects needs longer period of time (7.17 +/- 1.74 minute and 6.94 +/- 1.48 minute vs. 5.13 +/- 1.47 minute and 4.58 +/- 1.17 minute, p < 0.05 and p < 0.001).

Conclusion: the functional status of lower extremities in obese patients with DM is poorer than the non-obese subjects.
