Abstract
ObjectiveThe characteristics of dietary structure in overweight/obese type 2 diabetic patients were investigated for providing individualized medical nutrition therapy for diabetes mellitus.
MethodsA total of 103 out-patients (58 males, 45 females, ≥25 years) from the 900 Hospital of the Joint Logistics Team between January and June in 2017 were recruited and divided into 3 groups according to body mass index (BMI) : normal group (18.5<BMI<24.0 kg/m2, n=31), overweight group (24.0≤BMI<28.0 kg/m2, n=38) and obese group (BMI≥28.0 kg/m2, n=34). 3×24 hours dietary records were collected by weighing method including height, weight and waist circumference measuring. Mean daily intakes of total calorie, energy supply ratio of three major nutrients, intake of three major nutrients and dietary fiber were calculated and analyzed by software of trophic analysis. One-way analysis of variance was used for comparison among multiple groups.
Results(1) Total calorie intake: the differences of total calorie intake among 3 groups were statistically significant (F=4.321, P<0.05); it was higher in the obese group than that in the normal group [(2 488±894) vs (2 094±346) kcal (1 kcal=4.18 kJ), P<0.05]; while there were no significant differences between the overweight group and the normal group or the obese group (both P>0.05). (2) Energy supply ratio: there were no significant differences in energy supply ratio of carbohydrate, protein and fat among 3 groups (all P>0.05) . (3) Intake: differences were significant in the carbohydrate intake among 3 groups (F=6.755, P<0.05), intake in the obese group was higher than those in the normal group or the overweight group [(332±114) vs (265±52) vs (276±60) g, all P<0.05]. There was no significant difference between the normal and the overweight group (P>0.05). There were no significant differences in protein, fat and dietary fiber intake among 3 groups (all P>0.05).
ConclusionCompared with normal weight patients with type 2 diabetics, obese type 2 diabetic patients have excessive daily energy intakes and excess energies, mainly due to excessive carbohydrate intake.
