This study was conducted to test the effect of a diabetic camp program on the fasting blood sugar in type 2 diabetic patients. The subjects of the study consisted of 33 diabetic patients who had participated with a diabetic camp program in the YangPung area from August 12 to August 15, 1998. Wilcoxon signed rank test was used for the significance of the differences between values before and after the diabetic camp program. The fasting blood glucose level, before of the closing day at the diabetic camp, was lower than that of the opening day. When comparing the blood glucose levels before meals, between the early and later part of the diabetic camp, fasting blood glucose levels before breakfast by the 4th day in the later part of the diabetic camp were lower than those of the 2nd day in the early part. Blood glucose level before lunch by the 4th day, in the later part of the diabetic camp, were lower than those of the 2nd day in the early part. Blood glucose levels before dinner by the 3rd day, in the later part of the diabetic camp, were lower than those of the 1st day in the early part. Blood glucose levels before sleep by the 3rd day, in the later part of the diabetic camp, were lower than those of the 1st day in the early part.
