百岁老人被用作健康老龄化和长寿的典范。饮食是影响中年人和老年人死亡率的已知因素。然而，目前尚不清楚饮食是否对100多岁的生存有影响。本系统性综述的目的是总结以下方面的证据：（i）成年晚期饮食模式与100岁以上生存率之间的相关性，以及（ii）与100岁以上生存率呈正相关的饮食模式的共同特征。我们在MEDLINE和EMBASE中进行了系统性文献检索，并在截至2021年6月4日的四个长寿项目主页上进行了手动检索。我们检索了队列研究和病例对照研究，这些研究调查了在招募时年龄≥ 65岁的个体中，无论其健康状况和居住地如何，饮食模式与全因死亡率之间的关系。如果随访进行得太早，无法使人群或其中的亚组达到100岁以上，则排除研究。在3 685份已确定的记录中，检索了108份报告并进行了全文筛选。没有研究符合我们的纳入标准，因此审查过程中没有发现合格的研究，因此没有进行偏倚风险评估和数据综合。没有研究调查成年晚期的饮食模式与活到100岁以上的关系。我们观察到，截至2021年6月，已发表的队列研究调查了年龄最大的老年人不同饮食模式的全因死亡风险，但在队列可能达到100岁之前进行了随访。然而，确实存在这样的队列，即几十年前收集了成年人饮食习惯的数据，并且在2022年的随访中，参与者将达到100岁以上。审查方案发表在南丹麦大学的研究门户网站（Poulsen et al. Dietary Patterns and Survival to 100 + Years：Protocol for a Systematic Review of cohort and case-control studies南丹麦大学的研究门户网站：南丹麦大学，2021），可在www.example.com上查阅。与方案相比，我们在本报告中明确了研究问题的目的（i），在"成年期"中增加了"晚期"。在线版本包含补充材料，可通过10.1186/s13690 - 022 - 00914 - 2获得。
Centenarians are used as a model of healthy ageing and longevity. Diet is a factor known to affect mortality in middle aged adults and elderly. However, it is unknown whether diet has an impact on survival to 100 + years. The aims of this systematic review were to summarize the evidence on (i) the association between dietary patterns in late adult life and survival to 100 + years and (ii) the common characteristics across dietary patterns that are shown to be positively associated with survival to 100 + years. We performed a systematic literature search in MEDLINE and EMBASE, and a hand search at four longevity projects homepages up to 4 June 2021. We searched for cohort and case–control studies investigating the association between dietary patterns and all-cause mortality among individuals aged ≥ 65 years at enrolment regardless of their health status and residence. Studies were excluded if follow-up was performed too soon to allow the population or a subgroup of it to have become 100 + years of age. Of 3,685 identified records 108 reports were retrieved and full text screened. No studies met our inclusion criteria, thus the review process resulted in no eligible studies found. Hence, no risk of bias assessment and no synthesis of data was performed. No studies have investigated dietary patterns in late adult life in relation to survival to 100 + years of age. We have observed that as of June 2021 published cohort studies exist investigating all-cause mortality risk from different dietary patterns among the oldest old, but follow-up has been performed before the cohort could have reached 100 years of age. However, cohorts do exist where data on dietary habits in adult life has been collected decades ago and where follow-up in 2022 will allow the participants to have become 100 + years old. The review protocol is published at University of Southern Denmark’s Research Portal (Poulsen et al. Dietary Patterns and Survival to 100 + Years: Protocol for a Systematic Review of cohort and case–control studies University of Southern Denmark's Research Portal: University of Southern Denmark, 2021) available at https://portal.findresearcher.sdu.dk/en/publications/kostm%C3%B8nstre-og-overlevelse-til-100-%C3%A5r-protokol-for-en-systematisk. We have specified aim (i) of our research question in this report compared to the protocol, by adding “late” to “adult life”.
