To our knowledge, the independent association between central obesity, defined by waist circumference (WC) or waist-to-hip ratio (WHR), and diabetic retinopathy (DR) remains unknown in Chinese individuals.
The study was conducted in two stages. First, the relationship between WC or WHR and DR was estimated in a case-control set (DR vs. non-DR) for the whole population before and after propensity score matching. Subsequently, a systematic review and meta-analysis was performed on evidence from the literature to validate the relationship.
Of 511 eligible patients, DR (N = 156) and non-DR (N = 156) patients with similar propensity scores were included in the propensity score matching analyses. Central obesity (defined by WC) was associated with risk of DR (odds ratio [OR] 1.07, 95% confidence interval [95% CI] (1.03–1.10). The meta-analysis showed that central obesity significantly increased the risk of DR by 12% (OR 1.12, 95% CI 1.02–1.22). Analysis of data from 18 studies showed a significant association between continuous body mass index and risk of proliferative DR (OR 0.95, 95% CI 0.93–0.98; I = 50%).
Central obesity, particularly as defined by WC, is associated with the risk of DR in the Chinese population.
据我们所知，在中国人群中，由腰围（WC）或腰臀比（WHR）定义的中心性肥胖与糖尿病视网膜病变（DR）之间的独立关联尚不清楚。
该研究分两个阶段进行。首先，在倾向得分匹配前后的全人群病例对照组（DR组与非DR组）中评估WC或WHR与DR之间的关系。随后，对文献证据进行系统评价和荟萃分析以验证这种关系。
在511例符合条件的患者中，倾向得分匹配分析纳入了倾向得分相似的DR患者（N = 156）和非DR患者（N = 156）。中心性肥胖（由WC定义）与DR风险相关（比值比[OR] 1.07，95%置信区间[95%CI]为(1.03 - 1.10)）。荟萃分析表明，中心性肥胖使DR风险显著增加12%（OR 1.12，95%CI 1.02 - 1.22）。对18项研究数据的分析显示，连续的体重指数与增殖性DR风险之间存在显著关联（OR 0.95，95%CI 0.93 - 0.98；I² = 50%）。
中心性肥胖，尤其是由WC定义的中心性肥胖，与中国人群的DR风险相关。
