饮食质量是影响糖尿病前期的重要因素，但很少有研究应用中国膳食平衡指数(DBI-16)来评价糖尿病前期个体的饮食质量，探讨饮食质量与糖尿病前期的关系。在我们的研究中，分别计算下限分数、上限分数和饮食质量距离，以评估基于每个食物组的饮食质量。用Logistic回归计算各亚组不良饮食质量导致糖尿病前期的优势比(OR)和95%可信区间(95%CI)。结果显示，与非糖尿病前期患者相比，糖尿病前期患者在谷类、盐类摄入过多，蔬菜、鱼类和饮食种类摄入不足(均P<；0.01)。不良的饮食质量与糖尿病前期风险的增加显著相关(OR：1.45，95%CI：1.29-1.63)，特别是在生活在农村地区的受试者(OR：1.63，95%CI：1.25-1.76)、腹型肥胖者(OR：1.58，95%CI：1.36-1.85)、吸烟者(OR：1.58，95%CI：1.30-1.93)、饮酒者(OR：1.57，95%CI：1.28~1.93)和不饮茶者(OR：1.64，95%CI：1.42~1.88)。总而言之，不良的饮食质量与糖尿病前期风险的增加显著相关。
Dietary quality is an important factor influencing prediabetes, but few studies have applied the Chinese Diet Balance Index (DBI-16) to evaluate the dietary quality of individuals with prediabetes and explore the associations between dietary quality and prediabetes. In our study, the lower-bound score, higher-bound score and diet quality distance, were respectively calculated to assess dietary quality based on each food group. Logistic regression was used to calculate the odds ratio (OR) and 95% confidence interval (95%CI) of unfavorable dietary quality leading to prediabetes in every subgroup. The results were shown that individuals with prediabetes had excessive intake in the categories of cereals, salt and inadequate intake in vegetables, fish and diet variety than participants without prediabetes (all P.< 0.01). Unfavourable dietary quality was significantly associated with an increased risk of prediabetes (OR: 1.45, 95%CI: 1.29-1.63), especially among the subjects who lived in rural areas (OR: 1.63, 95%CI: 1.25-1.76), those who had abdominal obesity (OR: 1.58, 95%CI: 1.36-1.85), those who smoked (OR: 1.58, 95%CI: 1.30-1.93), those who consumed alcohol (OR: 1.57, 95%CI: 1.28-1.93) and those who did not drink tea (OR: 1.64, 95%CI: 1.42-1.88). In Conclusion, unfavourable dietary quality was significantly associated with an increased risk of prediabetes.
