Results: Recent epidemiologic studies have demonstrated relationships between lifestyle modification and prevention of diabetes itselt or its complications. However, despite of its importance, lifestyle modification including dietary intervention is known as the most difficult field to carry out. The aims of this study were to evaluate the eating behavior of Korean type 2 diabetic patients from the viewpoint of regularity and to provide the basis for proper management of patients with irregular lifestyle.
Total 1374 subjects were included (697 diabetes; 55.6 ± 13.4 years, male 46.1% vs. 677 controls; 55.4 ± 13.3 years, male 44.4%, P = ns) and their eating behavior such as meal skipping patterns or meal time intervals (4∼6 hour defined as regular one) were analyzed by chi-square test. Dietary patterns such as total daily intake (kcal/kg of ideal BWt.) and daily amount of micronutrients (per 1,000 kcal) were subanalyzed between 2 meal (n=123) and 3 meal (n=560) taking groups by independent t-test only in diabetic patients.
The proportions of skipping meal were significantly lower in diabetic patients and those of irregular meal time intervals for breakfast-lunch or lunch-supper were not significantly different in both groups (Table).
Irregular eating behavior of type 2 diabetic patients and normal controls.
|Meal skipping patterns per day, % ( n)||Total||19.6|
|Irregular meal time intervals per day, % (n)||Breakfast-Lunch||18.4|
|Breakfast-Lunch & Lunch-Supper||59.8|
In the subanalysis of diabetic patients, 2 meal taking group have significantly lower total daily intake (28 ± 9 vs. 33 ± 9 kcal/kg of ideal BWt., P < 0.01), but showed significantly higher serum triglyceride level than 3 meal group after adjusting age (1.96 ± 1.41 vs. 1.74 ± 0.97 mM/L, P < 0.01). Amount of micronutrients such as calcium (259 ± 127 vs. 310 ± 177 mg/1,000 kcal, P < 0.01) or iron (7.2 ± 3.7 vs. 8.0 ± 3.7 mg/1,000 kcal, P < 0.05) were significantly lower in 2 meal group than in 3 meal group, respectively.
Irrespective of diet recommendations, diabetic patients who had irregular eating behavior were 59.8%, causing nutritional imbalance in calorie, lipid or micronutrients. These results suggest the necessity of not only more intensive education program but also more practical approach to guarantee the flexible lifestyle in type 2 diabetic patients with irregular lifestyle.
