目的 探讨饮食疗法对早期2型糖尿病患者血糖的影响.方法 将120例早期2型糖尿病患者按随机数字表法分为两组,每组60例,均予以常规药物治疗及护理,观察组在此基础上实施饮食疗法,出院后随访半年.治疗前后及随访期间观察患者血糖变化及夜间低血糖发生率.结果 治疗后两组空腹血糖、餐后2 h血糖水平均较治疗前有显著改善(P<0.05或0.01),但观察组较对照组改善更显著(P<0.01).随访发现,观察组夜间低血糖发生率(6.7%)显著低于对照组(21.7%)(P<0.05).结论 对早期2型糖尿病患者在常规药物治疗及护理的基础上联合饮食疗法,能够有效控制患者的血糖水平及夜间低血糖的发生.“,”Objective To explore the effects of diet therapy on blood glucose of patients early type 2 diabetes mellitus (T2DM). Methods A total of 120 patients with early T2DM were assigned to two groups of 60 ones each according to random number table,both groups received routine medication and nursing,on this basis observation group was plus diet therapy,and they were followed up for 6 months after discharge. Changes of blood glucose and the incidence of night hypoglycemia were observed before and after treatment as well as during follow-up. Results After treatment fasting blood sugar (FAS) and postprandial 2h blood sugar (P2BS) levels of both groups improved more significantly compared with pretreatment (P<0.05 or 0.01) and so did those in observation than in control group (P<0.01). During follow-up the incidence of night hypoglycemia was significantly lower in observation than in control group (6.7% vs. 21.7%,P<0.05). Conclusion Diet therapy on the basis of routine medication and nursing could effectively control blood glucose levels and the development of night hypoglycemia.
