Randomized controlled trial of prevention of diabetes

为了预防糖尿病，我们在糖耐量受损的参与者中进行了随机对照试验。本研究邀请了一个社区的年度健康检查参与者。共有102名参与者被纳入研究。参与者被随机分为干预组和对照组。在接受过该健康教育方法标准方案培训的社区卫生专业人员，在6个月健康教育计划标准方案的基础上，对干预组参与者进行自我血糖监测健康教育。六个月后，我们进行了健康相关行为的调查，以及血糖水平、糖化血红蛋白和体重指数的调查。我们观察到干预组参与者在日常生活中提醒的健康相关行为的数量发生了显著变化。干预组应限制的健康行为数量也显著增加。而干预组与对照组的差异无显著性差异。本研究表明，自我管理血糖监测有利于激励参与者保持其改善的生活方式。

For prevention of diabetes, we conducted randomized controlled trial among participants with impaired glucose tolerance. Participants of annual health check-up in a community were invited to this study. A total of 102 participants were enrolled. Participants were randomly divided into a intervention group and a control group. Health professionals in a community, who had been trained standard protocol of this health education method, conducted the health education to participants in the intervention group using self-administered blood sugar monitoring in addition to standard protocol of 6 month health education program.After six month, we conducted the survey of health related behaviors as well as blood sugar levels, hemoglobin A1c and body mass index.We observed significant change among the intervention group in the number of health related behaviors which participants reminded of in daily life. Number of health behaviors, which should be restricted, were also significantly increased among the intervention group. However these differences were not significantly different between the intervention group and the control group.This study suggests that self-administered blood sugar monitoring is favorable to motivate participants to maintain their improved life styles.
