摘 要:目的探讨低热量饮食对肥胖型2型糖尿病(T2DM)患者胰岛素水平及胰岛素抵抗(IR)的影响。方法选取2014年3月至2015年2月在石家庄市第三医院门诊初诊为肥胖型T2DM患者[体质量指数(BMI)≥25 kg/m2]150例,按随机数表法分为低热量饮食组75例和普通饮食组75例。低热量饮食组患者采用低热量饮食,每日总热量1 000 kcal;普通饮食组患者则采用普通饮食,两组均干预8周。检测饮食干预前后两组患者的体质量、BMI、空腹血糖(FBG)、空腹胰岛素(FINS)、三酰甘油(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)和高密度脂蛋白胆固醇(HDL-C)水平,计算胰岛素抵抗指数(HOMA-IR)。结果干预前,低热量饮食组患者的体质量、BMI、FBG、FINS、HOMA-IR、TG、TC、HDL-C、LDL-C分别为(73.0±13.2)kg、(26.8±6.4)kg/m2、(9.3±5.1)mmol/L、(18.3±7.1)m U/L、(3.9±1.1)、(3.7±1.2)mmol/L、(6.4±1.0)mmol/L、(1.5±0.5)mmol/L、(3.8±0.2)mmol/L,普通饮食组分别为(74.6±11.3)kg、(27.4±8.7)kg/m2、(9.5±4.3)mmol/L、(17.5±8.2)m U/L、(3.9±1.2)、(3.6±1.3)mmol/L、(6.3±1.5)mmol/L、(1.6±0.4)mmol/L、(3.7±0.8)mmol/L,两组比较差异均无统计学意义(P>0.05)。干预后,低热量饮食组患者的体质量、BMI、FBG、FINS、HOMAIR、TG、TC以及LDL-C水平分别为(67.5±12.4)kg、(22.3±3.1)kg/m2、(5.3±1.3)mmol/L、(13.2±1.4)m U/L、(2.5±1.1)、(2.5±0.8)mmol/L、(4.1±1.5)mmol/L、(3.0±0.4)mmol/L,明显低于干预前及普通饮食组同期的(72.8±12.4)kg、(26.1±6.6)kg/m2、(9.1±1.4)mmol/L、(16.9±1.8)m U/L、(3.5±1.2)、(3.6±1.5)mmol/L、(5.8±1.6)mmol/L、(3.9±0.3)mmol/L(P<0.05),HDL-C水平为(1.7±0.3)mmol/L,高于干预前及普通饮食组同期的(1.5±0.4)mmol/L,差异均有统计学意义(P<0.05)。普通饮食组在干预前后各观察指标之间比较差异均无统计学意义(P>0.05)。结论低热量饮食能有效降低肥胖型T2DM患者胰岛素水平,改善IR。Objective To study the effects of low caloric diet on the insulin level and insulin resistance (IR) inobese patients with type 2 diabetes mellitus (T2DM). Methods A total of 150 obese patients with T2DM (body mass in-dex [BMI]≥25 kg/m2) were selected from March 2014 to February 2015 in Shijiazhuang Third Hospital, and the pa-tients were randomly divided into the low caloric diet group (75 cases) and the normal diet group (75 cases) according torandom number table. The low caloric diet group underwent low calorie diet (1 000 kcal/d), and the normal diet group re-ceived normal diet. The two groups were intervened for 8 weeks. The levels of weight, BMI, fasting blood glucose(FBG), fasting insulin (FINS), triglyceride (TG), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C) andhigh density lipoprotein-cholesterol (HDL-C) were detected in the two groups before and after the diet intervention, and thenthe insulin resistance index (HOMA-IR) was calculated. Results The levels of weight, BMI, FBG, FINS, HOMA-IR,TG, TC, HDL-C and LDL-C were (73.0±13.2) kg, (26.8±6.4) kg/m2, (9.3±5.1) mmol/L, (18.3±7.1) mU/L, (3.9±1.1),(3.7±1.2) mmol/L, (6.4±1.0) mmol/L, (1.5±0.5) mmol/L, (3.8±0.2) mmol/L respectively in low calorie diet group be-fore the intervention, versus (74.6±11.3) kg, (27.4±8.7) kg/m2, (9.5±4.3) mmol/L, (17.5±8.2) mU/L, (3.9±1.2), (3.6±1.3) mmol/L, (6.3±1.5) mmol/L, (1.6±0.4) mmol/L, (3.7±0.8) mmol/L respectively in normal diet group (P〉0.05). Thelevels of weight, BMI, FBG, FINS, HOMA-IR, TG, TC and LDL-C in low calorie diet group after the intervention were(67.5±12.4) kg, (22.3±3.1) kg/m2, (5.3±1.3) mmol/L, (13.2±1.4) mU/L, (2.5±1.1), (2.5±0.8) mmol/L, (4.1±1.5) mmol/L,(3.0±0.4) mmol/L respectively, which were significantly lower than those before the intervention and the corresponding(72.8±12.4) kg, (26.1
