Study of the dietary risk factors in newly diagnosed T2DM patients in Guangzhou district

Objective To investigate the dietary risk factors in T2DM population in Guangzhou district. Method We selected newly-diagnosed T2DM cases(n=126) and healthy controls(n=126),applied the food frequency questionnaire investigation,and measured TC,TG,HDL,LDL and carried out physical examination,and analyzed the differences between the two groups.Results The daily intakes included: energy (2867.75±748.04)kcal,fat(95.99±19.85)g,protein(100.59±29.85)g,and dietary cholesterol(334.92±94.63)mg.Serum TG,systolic pressure and diastolic pressure were significantly higher in case group than in control group(P0.05),while the intake of dietary fiber was significantly lower in case group(P=0.011).The differences between the two groups in the aspects of the intakes of carbohydrate,serum TC,HDL-C and LDL-C were not significant(P=0.07).Conclusion The risk of T2DM decreases by controlling energy intake,depressing the ratio of fatty energy.The dietary pattern may contribute to the increasing prevalence of T2DM in this area.
