PROJECT SUMMARY / ABSTRACT Osteoarthritis (OA) is the most common form of arthritis and the major cause of activity limitation and physical disability in older people. In the absence of disease modifying therapy, there is an urgent need for effective, widely available approaches to aid in the prevention and management of this common condition. Dietary factors associated with inflammation, obesity and other metabolic risk factors appear to play a role in OA pathogenesis. However, few human studies have studied the association between dietary factors and risk of future knee OA development. We have preliminary data from the Osteoarthritis Initiative (OAI), a large cohort with repeated measures of OA symptoms and radiographic outcomes, demonstrating that the Western dietary pattern, characterized by high intakes of red/ processed meats, refined grains, desserts / sweets, was associated with increased risk of radiographic knee OA. In contrast, the Prudent dietary pattern characterized by high intakes of fruits/ vegetables, legumes, whole grains, poultry, and fish was associated with reduced risk of knee OA. Hence, adherence to a healthy diet may provide a potential strategy for the prevention of knee OA. However, self-report dietary assessment methods, such as food-frequency questionnaires (FFQs) and diet records, may be subject to recall bias and measurement error. Biomarkers of dietary intake taking into account the nutrient bioavailability and metabolism may better represent a long-term nutritional status. Recently, metabolomics, by measuring a large number of downstream components or metabolic products (metabolites), provides the most integrated profile of biological status reflecting environmental, dietary and genetic interactions, and therefore may more precisely define dietary exposures and provide better estimates of disease risk in epidemiologic studies. To date, intervention studies have identified a variety of metabolites related to the dietary intake of major foods. More than 50 of them have been validated by multiple studies. To date, no study has ever assessed the association between metabolites of dietary intake and future risk of knee OA. We propose a nested case-control study in OAI cohort including 261 incident knee OA cases and 261 matched controls to examine whether individual metabolites and metabolomic profiles of dietary intake predict subsequent risk of development of knee OA, and whether diet-related metabolites and metabolomic profiles influence imaging biomarkers of knee OA. Finally, we will examine whether imaging biomarkers of knee OA mediate the associations of diet-related metabolomic profiles with risk of knee OA. This study will help to identify dietary factors associated with knee OA development, and offer the potential for effective OA prevention strategies; therefore, it may have large public health and clinical implications.

项目总结/摘要 骨关节炎（OA）是关节炎的最常见形式，也是活动受限的主要原因， 老年人的身体残疾。在缺乏疾病修饰疗法的情况下，迫切需要 有效的，广泛可用的方法，以帮助预防和管理这种常见的条件。 与炎症、肥胖和其他代谢危险因素相关的饮食因素似乎在以下方面发挥作用： OA发病机制。然而，很少有人类研究研究饮食因素之间的联系， 和未来膝关节OA发展的风险。我们有来自骨关节炎倡议（OAI）的初步数据， 通过对OA症状和影像学结局进行重复测量的大型队列研究，证明 西方饮食模式，特点是大量摄入红肉/加工肉类、精制谷物、甜点/ 与放射学膝关节OA风险增加相关。相比之下， 以水果/蔬菜、豆类、全谷物、家禽和鱼类的高摄入量为特征， 降低膝关节OA的风险。因此，坚持健康的饮食可能会提供一个潜在的战略， 预防膝关节OA。然而，自我报告的饮食评估方法，如食物频率， 调查问卷（FFQ）和饮食记录，可能会受到回忆偏差和测量误差。的生物标志物 膳食摄入量考虑到营养素的生物利用度和代谢可能更好地代表了长期的 营养状况最近，代谢组学，通过测量大量的下游组分或 代谢产物（代谢物），提供了反映生物状态的最完整的概况 环境、饮食和遗传相互作用，因此可以更精确地定义饮食暴露 并在流行病学研究中提供更好的疾病风险评估。到目前为止，干预研究已经 确定了与主要食物的膳食摄入量有关的各种代谢物。其中有50多人被 经过多项研究验证。迄今为止，还没有研究评估代谢物之间的关联 饮食摄入量和膝关节OA的未来风险。我们建议在OAI队列中进行巢式病例对照研究 包括261例膝关节OA病例和261例匹配对照，以检查个体代谢物是否 饮食摄入的代谢组学特征可预测随后发生膝关节OA的风险， 饮食相关代谢物和代谢组学特征影响膝关节OA的成像生物标志物。最后我们将 检查膝关节OA的成像生物标志物是否介导饮食相关代谢组学特征的相关性 有膝关节OA的风险。这项研究将有助于确定与膝关节OA发展相关的饮食因素， 提供有效的OA预防策略的潜力;因此，它可能具有很大的公共卫生和临床意义。 影响
