【摘要】 目的:探讨正念饮食意识训练对H型高血压患者的膳食结构、血同型半胱氨酸水平影响的机制。方法:选取2023年3月至4月青岛某三甲医院体检中心的H型高血压患者70例,按随机数字表法分为干预组35例、对照组35例,对照组予以常规健康教育,干预组在健康教育的基础上实施为期8周的正念饮食意识训练,以饮食质量指数(DQI)、五因素正念量表(FFMQ)、血同型半胱氨酸(Hcy)作为评估指标,对比两组干预末、干预后3个月各指标的差异。结果:干预组与对照组各失访3例,两因素重复测量方差分析结果示组别与时间的交互作用有统计学意义,干预末,两组膳食结构、血同型半胱氨酸水平、正念水平差异有统计学意义,干预后3个月,干预组与对照组各指标差异无统计学意义。干预组的干预末较干预前正念水平分数变化值能够通过膳食结构的变化值的中介作用预测同型半胱氨酸水平变化值,该直接效应(0.26)和中介效应(0.11)分别占总效应(0.37)的70.2%和29.8%。结论:正念饮食意识训练对H型高血压患者具有一定的疗效,可改善其膳食结构,降低血同型半胱氨酸水平,提高正念水平,但正念饮食意识训练的长期疗效不佳。膳食结构在正念水平与同型半胱氨酸水平的关系中起着中介作用,为正念饮食训练降低H型高血压患者的同型半胱氨酸水平提供理论支持。更多还原

【Abstract】 Objective:To explore the mechanism of the effect of Mindfulness-Based Eating Awareness Training on the dietary structure and blood homocysteine levels of patients with type H hypertension.Methods:A total of 70 patients with type H hypertension were randomly divided into an intervention group of 35 cases and a control group of 35 cases using a random number table.The control group received routine health education.The intervention group received 8 weeks of MB-EAT on the basis of the control group,using the Dietary Quality Index(DQI) and Five Factor Mindfulness Scale(FFMQ) Blood homocysteine(Hcy) was used as an evaluation indicator to compare the differences in various indicators between the two groups at the end of intervention and 3 months after intervention.Results:The results showed that 3 cases were lost in the intervention group and 3 cases in the control group.The analysis of variance for repeated measurements showed a statistically significant interaction between groups and time.At the end of the intervention,there were significant differences in dietary structure,blood homocysteine levels,and mindfulness levels between the two groups.After 3 months of intervention,there was no significant difference in all indicators between the intervention group and the control group.The changes in mindfulness at the end of intervention compared to before intervention in the intervention group can predict changes in homocysteine levels through the mediating effect of dietary structure scores.Th e direct effect(0.26) and mediating effect(0.11) account for 70.2% and 29.8% of the total effect(0.37),respectively.Conclusion:MB-EAT has a certain therapeutic effect on H-type hypertension patients with obesity,which can improve their dietary structure,reduce blood homocysteine levels,and increase mindfulness levels.However,the long-term efficacy of MB-EAT is not satisfactory.The dietary structure plays a mediating role in the relationship between mindfulness levels and homocysteine levels,providing theoretical support for mindfulness diet training to reduce homocysteine levels in patients with type H hypertension.更多还原
