High Carbohydrate Diet and Total Daily Calories Induce Glucose Abnormalities in Korean Population.

Body: The aim of this study was to examine the association between dietary patterns and glucose abnormalities using Korean dietary evaluation program. This was a part of 2[sup nd] Incheon Chronic Disease Management System Study(2006). We surveyed 1,000 subjects in Hwasu-Dong by a cross-sectional observational study on September to December 2006. Among them, 178 subjects (55 male, 123 female) were evaluated about dietary patterns using CAN-Pro 3.0. CAN-Pro 3.0 is a dietary evaluation program authorized by the Korean Nutrition Association in 2005. Subjects diagnosed three groups (normal, prediabetes and diabetes) by American Diabetes Association criteria using 75g oral glucose tolerance test. Prediabetes includes impaired fasting glucose, impaired glucose tolerance and combined state. We also performed physical and laboratory examinations. Mean age is 49.7+12.7 years. Among 178 subjects, normal person was 21 (11.8%), IFG 41 (23.0%), IGT 37(20.8%) and combined 20(11.2%) and newly diagnosed diabetes was 39(21.9%). In IFG, IGT, combined and newly diagnosed diabetes group, intake of carbohydrate(g) were higher than normal group, respectively (303.9±96.8g, 294.8±77.1g, 266.3±64.0g and 309.6±100.9g vs 235.1±39.1g, p<0.01). In IFG, IGT, combined and newly diagnosed diabetes group, intake of total daily calories(kcal) were higher than normal group, respectively(1974.4±543.8kcal, 1880.5±480.9kcal, 1681.1±384.3kcal and 1843.7±429.7kcal vs 1564.3±238.6kcal, p<0.01). Among the groups, there were no differences with dietary total fatty acid, cholesterol, protein, fiber and vitamin. The high consumption of carbohydrate and over-dosed total daily calories were positively associated with glucose abnormalities or risk factors for diabetes in Korean population. [ABSTRACT FROM AUTHOR]
