目的探讨住院T2DM患者能量供给量与静息能量消耗(REE)的关系,为临床营养治疗确立适宜能量供给量提供参考依据。方法选择内分泌科T2DM患者97例,根据BMI水平分为体重正常组(A组)、超重组(B组)和肥胖组(C组)。入院后即采用通用系数法为患者确立能量供给量,并通过能量调整使患者的空腹及3餐后2hPG水平稳定。用代谢车测定患者REE,比较3组患者能量供给量与REE的关系,并由此研究出供能系数。结果 3组患者治疗后空腹、3餐后2hPG较治疗前均降低(P<0.05),并基本达到血糖控制目标;A组患者能量供给量与消耗量基本达到平衡,B组和C组患者能量供给量低于消耗量;REE随BMI水平升高而升高;A、B和C组患者供能系数分别为1.02、0.93和0.85(P<0.05),供能系数随BMI水平升高而降低。结论住院T2DM患者REE随BMI水平升高而升高,其能量供给量依据REE进行确立时,应考虑不同BMI水平及其相对应的供能系数。
Objective To investigate the relationship between energy supply and resting energy expenditure (REE) in hospitalized patients with type 2 diabetes and to provide a reference for establishing appropriate energy supply for clinical nutrition therapy. Methods A total of 97 T2DM patients with endocrine disease were selected and divided into normal weight group (A group), overweight group (B group) and obesity group (C group) according to the level of BMI. After admission, the universal factor method was used to establish the energy supply for the patient and the patient’s fasting and 2-h PG level after 3 meals were stabilized through energy adjustment. Metabolic car was used to measure the patients’ REE. The relationship between energy supply and REE was compared between the three groups, and the power supply coefficient was studied. Results After treatment, fasting group and postprandial 2hPG were lower than those before treatment (P <0.05), and reached the goal of blood glucose control basically. The energy supply and consumption of group A were basically balanced, and the energy of group B and group C The supply of REE increased with the increase of BMI. The energy supply coefficients of patients in groups A, B and C were 1.02, 0.93 and 0.85, respectively (P <0.05). The energy supply coefficient decreased with the increase of BMI . Conclusions REE in hospitalized patients with T2DM increases with the increase of BMI. When the energy supply of REE is established according to REE, different levels of BMI and corresponding energy supply coefficients should be considered.
