12分钟步行试验对糖尿病运动干预效果的评价

Evaluation on 12 Minutes Walking Test of Activity Intervention for Diabetes Patients

[目的]探讨12分钟步行试验对社区老年糖尿病患者运动干预效果评价的有效性及意义。[方法]2006年5月～10月，在大连市选取城市社区108名老年2型糖尿病患者，指导干预组进行步行运动，其中干预A组27例（每周3次，每次步行30min）．干预B组27例（每周3次，每次步行60min），干预C组24例（每周5次，每次步行60min），对照组26例（不步行运动），各个干预组实施6个月的步行运动干预，进行12分钟步行试验测试。[结果]步行运动干预后，步数、步行运动消耗热能及i2分钟步行距离各干预组均有不同程度的增加（Pd0．01或Pd0．05）；对照组的差异无统计学意义（P〉0．05）。干预前后12分钟步行试验差值与空腹血糖、甘油三酯、胆固醇的差值间均存在负相关（r=-0．301、-0．418、-0．266）。[结论]12分钟步行试验可以作为对社区老年糖尿病患者运动干预效果进行客观评价的重要指标。

[Objective] To investigate and evaluate the method and effect of activity intervention for old diabetic patients. [Methods]The 108 elderly diabetes patients were randomly selected from Dalian city community and divided into four intervention groups, from May to October, 2006. Group A had 27 patients（3 times/week,30 rain/time）, group B had 27 patients（3 times/week, 60 rain/time）,group C had 24 patients（5 times/week,60 rain/time）, and the control group had 26 patients （non walking activity）, respectively. 12 minute test was detected for intervention groups after 6 months of walking activity intervention. ~Results] After walking activity intervention, the number of steps, the consumed energy of walk exercise and walking distances in 12 minutes of all the intervention exercise groups,except the control group, have increased to some extent（ P 〈0.01 or P〈0.05）. There was a negative correlativity between changes in distance among 12 minute and changes in FBG,TG,TC （ r =-0. 301 ,-0. 418,-0. 266）. [Conclusion]The 12 minute walking test can be taken as a key index to evaluate the effect of activity intervention for elderly diabetes patients.
