摘 要 目的:分析我国血糖指数与血糖负荷相关饮食的研究现状和发展趋势,为进一步的研究及护理人员的饮食教育提供参考。方法:以三大中文数据库为数据来源,检索2005—2015年血糖指数与血糖负荷相关饮食文献,分别从纳入文献的年代、文献类型、第一作者单位所在省市、发表文献的机构类型、研究的类型、研究对象、期刊分布、获得基金资助的情况等方面进行统计与分析。结果:共检出384篇有效文献,文献数量呈增长趋势,但速度较为缓慢,内容以相关饮食干预为主。其中《营养学报》载文量最多;研究成果多来自于医院;基金项目较少。结论:近10年来,血糖指数与血糖负荷相关饮食的研究取得了一定的进展,但仍有較大的发展空间,文献的地区分布和研究类型分布不均衡,同时文献质量也亟待提高,饮食干预研究将是该领域的研究重点和难点,同时应加强对描述性研究的关注。

ABSTRACT Objective: To analyze the research status and development trend of diet related to the glycemic index and glycemic load so as to provide reference for further researches and clinical diet education. Methods: Literatures about glycemic index and glycemic load were systematically searched in three Chinese databases from 2005 to 2015 and then the literatures found were analyzed in their annual distribution, literature type, province and city distribution, organization distribution, the type of research, the research object, journal distribution, funds distribution. Results: A total of 384 literatures were included in the analysis and the number of literatures was slowly increasing. Most of the contents were about dietary interventions and the largest number of literatures were published in Journal of Nutrition and from hospitals. However, only a small number of the literatures were funds-supported. Conclusion: Some progress has been made in diet research related to glycemic index and glycemic load since recent decade but there is still room for development. Region distribution of literature and research type distribution were not balanced. At the same time, the quality of papers is remained to be improved. The studies on diet intervention will be the focus and difficulties of research in this area and meanwhile great attention should be paid to descriptive studies.

糖尿病是现代社会的高发病。国际糖尿病联盟公布的数据显示:2013年全球20~79岁成年人的糖尿病患病率为8.3%,糖尿病总人数达到3.82亿[1]。同时,2013年美国医学会杂志报道[2],中国成人糖尿病的发病率已达11.6%,糖尿病已成为严重影响国人身心健康的公共卫生问题。饮食治疗是糖尿病自然病程中任何阶段都必不可少的措施,是糖尿病治疗的基础[3]。血糖指数和血糖负荷是评价膳食血糖效应的重要指标[4],其较好地弥补了食物交换份法在饮食控制与饮食教育中的不足,在指导糖尿病患者合理饮食方面发挥了较大的作用[5-8]。……
