目的了解广州地区初诊T2DM人群膳食营养素的摄入现状并分析其与T2DM发生的关系。方法在体检人群中选取初诊T2DM病例和对照人群,采用半定量食物消耗频度表(FFQ)进行膳食问卷调查,同时进行TC、TG、HDL、LDL及一般体格检查,分析两组间营养素及生化指标的差异。结果病例组每日能量、脂肪、蛋白质、膳食胆固醇摄入量,血清TG,收缩压和舒张压均高于对照组(P<0.05),膳食纤维每日摄入量则明显低于对照组(P=0.011),碳水化合物每日摄入量、血清TC、HDL-C和LDL-C在两组间差异无统计学意义(P>0.05)。结论控制能量摄入,降低脂肪供能比,有利于降低本地区T2DM的发病风险。本地区人群T2DM患病现状及膳食不合理现象严竣,需加强防治。
Objective To understand the status of dietary intake of newly diagnosed T2DM population in Guangzhou and to analyze its relationship with T2DM. Methods The newly diagnosed T2DM patients and control subjects were selected from the physical examination population. The food quality questionnaire was used to measure the food intake, and the levels of TC, TG, HDL, LDL and general physical examination were also analyzed. The effects of nutrients and biochemistry Differences in indicators. Results Daily energy, fat, protein, dietary cholesterol intake, serum TG, systolic blood pressure and diastolic blood pressure were higher in the case group than those in the control group (P <0.05). The daily dietary fiber intake was significantly lower than that in the control group P = 0.011). There was no significant difference in daily carbohydrate intake, serum TC, HDL-C and LDL-C between the two groups (P> 0.05). Conclusions Control of energy intake and reduction of fat to energy ratio is conducive to reducing the incidence of T2DM in this area. The prevalence of T2DM in the population of this region and the unhealthy dietary conditions need to be strengthened.
