[摘要] 目的 探讨中国中老年人糖尿病足与体重指数(BMI)、高密度脂蛋白胆固醇(HDL-C)、三酰甘油(TG)之间的关系。 方法 计算机检索PubMed、中国期刊全文数据库(CNKI)、万方科技期刊全文数据库,检索关于中国中老年人群糖尿病足相关危险因素的病例对照研究,检索时限2007年1月~2016年4月。采用RevMan5.3软件进行Meta分析,用固定效应模型或随机效应模型合并平均差值(MD值)及其95%可信区间(95%CI)分析各个相关因素,采用敏感性分析评估结果的稳定性,用漏斗图评估文献的发表偏倚。 结果 共纳入17篇文献,Meta分析显示,糖尿病足组与非糖尿病足组BMI(MD = -0.93,95%CI:-1.67~-0.18,P = 0.01)、HDL-C(MD = -0.20,95%CI:-0.33~-0.07,P = 0.004)差异有统计学意义,而两组TG(MD = 0.01,95%CI:-0.36~0.37,P = 0.98)比较差异无统计学意义。 结论 低BMI、低HDL-C可能是糖尿病足发生的危险因素。

[Abstract] Objective To evaluate the relationship between body mass index (BMI), high density lipoprotein cholesterol (HDL-C), triglyceride (TG) and diabetic foot in Chinese middle aged and elderly people. Methods The following database such as PubMed, China national knowledge infrastructure (CNKI), Wanfang database were searched to collect case-control study on related risk factors of diabetic foot in China. The retrieval time was from January 2007 to April 2016. The Meta analysis was performed by RevMan5.3 software. The risk factors were analyzed by fixed effect model or random effect model, count pooled mean difference (MD) and 95% confidence interval (95%CI), with stability evaluated by sensitivity analysis. Moreover, the funnel plot was to assess the published bias of articles. Results A total of 17 articles were included, Meta analysis showed that BMI (MD = -0.93, 95%CI: -1.67 - -0.18, P = 0.01), HDL-C (MD = -0.20, 95%CI: -0.33 - -0.07, P = 0.004) had significant difference between the diabetic foot group and the non-diabetic foot group; there was no obvious difference in TG (MD = 0.01, 95%CI: -0.36 - 0.37, P = 0.98) between diabetic foot group and the non-diabetic foot group. Conclusion Lower BMI and lower HDL-C may be the risk factors of diabetic foot.

糖尿病足是由糖尿病发展而来,严重者甚至造成足部坏疽、截趾、截肢并致死[1],给糖尿病患者带来极大痛苦和社会、经济负担[2]。我国糖尿病患者中约1/3并发糖尿病足[3],而中老年糖尿病患者病程长,极易发展成糖尿病足,因此對我国中老年糖尿病患者进行糖尿病足的预防有重要意义。在糖尿病足危险因素研究的结果中,对体重指数(BMI)、高密度脂蛋白胆固醇(HDL-C)、三酰甘油(TG)争议较多,为此我们通过Meta分析寻找糖尿病足与BMI、HDL-C、TG的相关性,为糖尿病足的早期预防提供依据。
