Obesity affects both medical and surgical outcomes in renal transplant recipients (RTRs). Dietary diversity, an important component of a healthy diet, might be a useful nutritional strategy for monitoring patients with obesity. In this cross-sectional study, the data of 85 eligible RTRs were analyzed. Demographic data, routine laboratory data, and 3-day dietary data were collected. Participants were grouped into nonobesity and obesity groups based on body mass index (BMI) (for Asian adults, the cutoff point is 27 kg/m). Dietary diversity score (DDS) was computed by estimating scores for the six food groups emphasized in the Food Guide. The mean age and BMI of participants were 49.7 ± 12.6 years and 24.0 ± 3.8 kg/m, respectively. In the study population, 20.0% (n = 17) were obese. DDS was significantly lower in obese participants than in those who were not obese (1.53 ± 0.87 vs. 2.13 ± 0.98; = 0.029). In addition, DDS was correlated with nutrition adequacy of the diet. Multivariate analysis showed that the odds of obesity decreased with each unit increase in DDS (odds ratio, 0.278; 95% confidence interval, 0.101-0.766; = 0.013). We conclude that patients with higher dietary diversity have a lower prevalence of obesity.
肥胖会影响肾移植受者（RTR）的医疗和手术结果。饮食多样性是健康饮食的重要组成部分，对于监测肥胖患者可能是一种有用的营养策略。在这项横断面研究中，分析了 85 名符合条件的 RTR 的数据。收集了人口统计学数据、常规实验室数据和 3 天的饮食数据。根据体重指数（BMI）（对于亚洲成年人，临界点为 27kg/m）将参与者分为非肥胖组和肥胖组。通过估计食物指南中强调的六类食物的分数来计算饮食多样性得分（DDS）。参与者的平均年龄和 BMI 分别为 49.7±12.6 岁和 24.0±3.8kg/m。在研究人群中，20.0%（n=17）为肥胖。肥胖参与者的 DDS 明显低于非肥胖参与者（1.53±0.87 与 2.13±0.98；=0.029）。此外，DDS 与饮食营养充足度相关。多变量分析显示，DDS 每增加一个单位，肥胖的几率就会降低（比值比，0.278；95%置信区间，0.101-0.766；=0.013）。我们得出结论，饮食多样性较高的患者肥胖患病率较低。
