Jekal, Lee, Kim, Park, Lee, Han, Kang, Lee, Kim, and Jeon: Effects of Walking and Physical Activity on Glucose Regulation among Type 2 Diabetics

Abstract

Background

Physical activity, especially walking is strongly recommended to control blood glucose among type 2 diabetic patients. Furthermore, physical activity is one of the most important tools to prevent secondary diabetes complications among type 2 diabetic patients such as retinopathy, nephropathy, neuropathy etc. The purpose of the study was to examine the association between the level of walking and physical activity and glucose control among Korean adults with type 2 diabetes.

Methods

A total of 250 patients with type 2 diabetes (98 males and 152 females) were recruited (mean age = 62.1 ± 10.2 years) in the current study. The height, weight, waist and hip circumference were measured, and the level of physical activity and total walking hour were measured by physical activity scale for elderly (PASE). High density lipoprotein cholesterol (HDL-C), total cholesterol, triglyceride, fasting glucose and oral glucose tolerance test, creatinine, uric acid, total protein, albumin, hemoglobin A1c were measured.

Results

After adjusting for potential covariates such as age, education, occupation income, smoking, and drinking, male patients who spent least time in walking were more likely to have 2 hour serum glucose level in oral glucose tolerance above 200 mg/dL than counterparts who spent most time in walking with age adjusted (Relative Risk (RR) = 11.75, 95% Confidence Interval (CI) = 1.94-71.00). Male patients who were in the least active group were 5.92 time (95% CI = 1.39-25.28) more likely to have 2 hour serum glucose level in oral glucose tolerance over 200 mg/dL than counterparts in the most active group. However, there was no significant finding in females.

Conclusions

The current study showed that physical activity and walking are effective method to maintain glucose tolerance among type 2 diabetic male patients.
