Background Walking is a popular, convenient and relatively safe form of exercise. However, there is few objective data for walking exercise. The aim of this study was to evaluate pedometer-determined physical activity defined as steps/day in type 2 diabetes mellitus. Therefore, it could be the basic data for programming walking exercise in diabetes mellitus. Methods Participants with type 2 diabetes who visited in 6 university hospitals on February, 2006 in Seoul and Kyung-gi area were recruited. The participants were asked their ambulatory activity with the given pedometer and calorimeter for 1 week. Total 240 (Male 122, Female 118) subjects who walked above 1000 steps/day were analyzed. We also collected their biochemical data from the medical records. Results Participants took 8532 ± 4130 steps for day (step/day) and energy expenditure were 320 ± 161 Cal/day. Steps/day was not significantly different between male and female, but energy expenditure was higher in male than female (P < 0.05). Steps/day was significantly lower in obese patients than non-obese patients (P < 0.001). BMI (r = -0.325, P < 0.001), waist circumference (r = -0.287, P < 0.001), triglyceride (r = 0.164, P < 0.018) showed significant inverse correlation with steps/day, but BUN (r = 0.165, P = 0.019) and HDL-cholesterol (r = 0.164, P = 0.018) were positive correlated with steps/day significantly. BMI (r = -0.14, P < 0.032) and cholesterol (r = -0.139, P < 0.041) showed significantly inverse correlation with energy expenditure and BUN (r = 0.187, P = 0.008) and HDL cholesterol (r = 0.145, P < 0.037) positively correlated with energy expenditure. Pedometer-determined steps/day was positively associated with energy expenditure (r2 = 0.824, P < 0.001). Conclusion This study showed the objective quantification of physical activity measured by simple and inexpensive pedometers. It could be used to recommend walking exercise since the practitioners can estimate steps/day for required energy expenditure.
