目的探讨饮食控制对中老年糖耐量低减(IGT)者丙二醛、总抗氧化能力的影响。方法对46例中老年糖耐量低减(IGT)者进行为期3个月的饮食干预,并在饮食干预前后测定其丙二醛、总抗氧化能力的变化。结果糖耐量低减(IGT)者丙二醛在干预前后分别为2.17±1.50与0.29±0.33;(P<0.01)差异有显著性;总抗氧化能力在干预前后分别为11.55±1.14与18.41±.83;(P<0.01)差异有显著性。结论饮食干预能有效降低IGT者丙二醛含量,提高总抗氧化能力。
Objective To investigate the effects of dietary control on malondialdehyde (MDA) and total antioxidant capacity in middle-aged and elderly patients with impaired glucose tolerance (IGT). Methods A total of 46 middle-aged and elderly patients with impaired glucose tolerance (IGT) were given diet intervention for 3 months, and their malondialdehyde and total antioxidant capacity were measured before and after diet intervention. Results Before and after intervention, malondialdehyde (IGT) was 2.17 ± 1.50 and 0.29 ± 0.33 respectively (P <0.01), and the total antioxidant capacity was 11.55 ± 1.14 and 18.41 ± .83; (P <0.01), the difference was significant. Conclusion Diet intervention can effectively reduce the malondialdehyde content of IGT and increase the total antioxidant capacity.
