Survey On Situation Of Diet Structure,Glycemic Load And Diet Knowledge Of Community Type2Diabetes Patients

Objective:To investigate diet knowledge and glycemic load (GL) situation of community type2diabetes patients, and analyze influence factor, to provide an available guidance of reasonable dietary for community type2diabetes patients, and finally improve patients life quality.Methods:Cluster sampling was used in this study,200cases of community type2diabetes patients were chosen as research object, and all of them would answer questionnaire, including patient’s general condition, present situation of diet knowledge, diet intake. The quality of questionnaire were controlled by preliminary investigations, repeated sampling, reliability test and other methods, and investigation quality was controlled via unified training investigators and auditors. Datas collected were analyzed by SPSS17.0statistical software package and nutrition calculator V2.4b, and patients’diets knowledge, dietary structure, glycemic load and influencing factors were assessed.Results:1. In general, most of these patients were partial lack of awareness of diet knowledge, and most lack of knowledge on glycemic index and glycemic load, followed by total energy control and food exchange rule.2. Diet knowledge level of200cases was positively correlated with their education and times that they had received diabetes education, and the analysis of conditioned Logistic regression showed the difference was statistically significant.3. Daily energy of200cases was1356.1±386.4kcal, and carbohydrate intake was163.4±45.8g, and fat intake was59.2±26.3g, and protein intake was40.8±14.1g, GL of average daily dietary was118.7±29.2, and GL of energy adjusted was90.9±22.7. GL of average daily dietary was significant positive correlated with daily energy and intake of carbohydrate, fat, and protein.4.16.0%of200cases had a normal diet intake, but75.5%of them had energy intake less than normal required amount.47.5%patients had50%less energy from carbohydrate than normal, and83.0%patients had30%more energy from fat than normal, and73.5%patients had normal energy from protein.5. The variability among daily energy, three nutritional substances for energy and GL of average daily diet of different economic levels family were statistically significant, and the variability among daily energy, three nutritional substances and GL of average daily dietary of different patients BMI were no statistically significant.6. The variability of dietary knowledge among daily energy, three nutritional substances and GL/1000were no statistically significant.Conclusion:1. Diet knowledge of most community type2diabetes patients was not comprehensive, especilly in glycemic index, glycemic load, total energy control and food exchange rule.2. Diet knowledge level of200cases was positively correlated with their education and times that they had received diabetes education, and patients who got a higher education and had received diabetes education more times had a better learning about diet knowledge.3. Daily intake energy, energy from carbohydrate and GL of average daily diet were lower than nomal, so it had proved that most of them could not have a reasonable diet structrue, and lower energy from carbohydrate but higher energy from fat, in that it seemed that these patients favor high-fat and low-carbohydrate diet.4. Fat intake was proved to be positively correlated with family economic level, and carbohydrate intake was negatively, so that daily dietary had not been individualized.5. Those patients in high score of diet knowledge might not have a healthy diet behavior.
