Abstract

People living with and beyond cancer (LWBC) are advised to follow World Cancer Research Fund (WCRF) dietary guidelines. However, there is no established methodology to assess adherence. This study aimed to: (i) develop methodology to process dietary recalls into a format comparable to WCRF guidelines and (ii) evaluate the impact of additional data processing on estimates of dietary intake, in people LWBC. Advancing Survivorship Cancer Outcomes Trial (ASCOT) participants completed two 24-h dietary recalls at four timepoints using myfood24. Five WCRF recommendations (limiting consumption of energy dense foods, red meat and processed meat, and increasing consumption of fruit and vegetables and wholegrains and pulses) were operationalized (e.g. ≤ 500 g red meat per week). Quality control checks indicated the need for additional processing, including changing portion sizes and choosing alternative items from myfood24 to improve accuracy. Compared to myfood24 output, the processed dietary data indicated lower intake of fruit and vegetables, and higher intake of NSP and AOAC fiber (all ps < 0.001). Developing methodology to allow assessment of 24-h dietary recall data against WCRF guidelines was possible and necessary but resource intensive. Additional data processing impacted estimates of the key foods and nutrients consumed by trial participants in a meaningful way.

使用24小时回顾来评估癌症特定饮食指南的依从性:来自癌症预后进展试验(ASCOT)的经验
建议癌症患者遵循世界癌症研究基金会(WCRF)的饮食指南。然而,没有确定的方法来评估依从性。本研究旨在:(i)开发一种方法,将饮食召回处理成与WCRF指南相当的格式;(ii)评估额外数据处理对低体重人群饮食摄入量估计的影响。推进癌症生存结局试验(ASCOT)的参与者使用myfood24在四个时间点完成了两次24小时饮食回顾。WCRF的五项建议(限制能量密集食物、红肉和加工肉的消费,增加水果和蔬菜、全谷物和豆类的消费)被实施(例如每周≤500克红肉)。质量控制检查表明需要额外的处理,包括改变份量和从myfood24中选择替代项目以提高准确性。与myfood24的结果相比,经过处理的膳食数据表明,水果和蔬菜的摄入量较低,而NSP和AOAC纤维的摄入量较高(均ps < 0.001)。根据WCRF指南制定方法评估24小时饮食召回数据是可能的,也是必要的,但需要大量资源。额外的数据处理以一种有意义的方式影响了试验参与者消耗的关键食物和营养素的估计。

期刊介绍: This timely publication reports and reviews current findings on the effects of nutrition on the etiology, therapy, and prevention of cancer. Etiological issues include clinical and experimental research in nutrition, carcinogenesis, epidemiology, biochemistry, and molecular biology. Coverage of therapy focuses on research in clinical nutrition and oncology, dietetics, and bioengineering. Prevention approaches include public health recommendations, preventative medicine, behavior modification, education, functional foods, and agricultural and food production policies.
