背景我们的目的是前瞻性地研究整体饮食质量（反映对饮食指南的遵守）和成功老龄化之间的关系，在一个以人群为基础的队列老年人。在这项基于人群的队列研究中，我们分析了1,609名49岁及以上成年人的10年随访数据，这些人在基线时没有癌症、冠状动脉疾病和中风，并且有完整的饮食数据。饮食数据收集使用半定量的食物频率问卷。根据国家膳食指南中的描述，为每位参与者分配了选定食物组和营养素的摄入量的总饮食评分（TDS）。分数越高，表明更密切地遵守饮食指南。成功的老龄化被定义为没有残疾、抑郁症状、认知障碍、呼吸系统症状和慢性疾病（癌症、冠状动脉疾病和中风）。在10年随访时，610名（37.9%）参与者死亡，249名（15.5%）参与者成功老化。多变量校正后，基线TDS每增加1个单位，10年后成功老化的几率增加8%，比值比1.08（95%置信区间1.00-1.15）。基线TDS最高（对饮食指南的依从性高）与最低四分位数（对指南的依从性差）的参与者10年后成功衰老的几率高58%，比值比为1.58（95%置信区间1.02-2.46）。通过多领域方法确定，更好地遵守推荐的国家饮食指南（更高的饮食质量）与成功衰老的可能性增加有关。
Background. We aimed to prospectively examine the relationship between overall diet quality (reflecting adherence to dietary guidelines) and successful aging in a population-based cohort of older adults.Methods. In this population-based cohort study, we analyzed 10-year follow-up data from 1,609 adults aged 49 years and older, who were free of cancer, coronary artery disease, and stroke at the baseline and who had complete dietary data. Dietary data were collected using a semiquantitative food frequency questionnaire. Total diet scores (TDS) were allocated for intake of selected food groups and nutrients for each participant as described in the national dietary guidelines. Higher scores indicated closer adherence to dietary guidelines. Successful aging was defined as the absence of disability, depressive symptoms, cognitive impairment, respiratory symptoms, and chronic diseases (cancer, coronary artery disease, and stroke).Results. At 10-year follow-up, 610 (37.9%) participants had died and 249 (15.5%) participants aged successfully. After multivariable adjustment, each 1-unit increase in TDS at baseline was associated with a 8% increased odds of successful aging 10 years later, odds ratio 1.08 (95% confidence interval 1.00-1.15). Participants in the highest (high adherence to dietary guidelines) versus lowest quartile (poor adherence to guidelines) of TDS at baseline had 58% higher odds of successful aging after 10 years, odds ratio 1.58 (95% confidence interval 1.02-2.46).Conclusions. Greater compliance with recommended national dietary guidelines (higher diet quality) was associated with an increased likelihood of successful aging, as determined through a multidomain approach.
