There are few concise tools to evaluate dietary habits in men with prostate cancer in Canada.
The aim was to develop a short food-frequency questionnaire (SFFQ) in a cohort of prostate cancer patients.
A total of 130 men with prostate cancer completed the SFFQ and a validated comprehensive food-frequency questionnaire (CFFQ). Both questionnaires were administered at baseline and 6 mo later.
We found good correlation between the SFFQ and the CFFQ for seafood, dairy, egg, fruits, potatoes, grains, soft drinks, and processed meat (Spearman rank correlation >0.5). Moderate correlation was found for meat, sweets, vegetables, protein, and carbohydrates (Spearman rank correlation: 0.3-0.5). We found a weaker correlation for total fat measured by SFFQ and CFFQ (Spearman rank correlation <0.3). There was adequate reproducibility during the 6-mo follow-up among all food groups and nutrients, with the exception of meat.
Our SFFQ can be considered an appropriate tool to be used for measuring the habitual dietary intake of prostate cancer patients. This trial was registered at www.clinicaltrials.gov as NCT03127631.
在加拿大，用于评估前列腺癌男性饮食习惯的简洁工具很少。
旨在为一组前列腺癌患者开发一份简短食物频率问卷（SFFQ）。
共有130名前列腺癌男性完成了SFFQ和一份经过验证的综合食物频率问卷（CFFQ）。两份问卷均在基线时和6个月后进行发放。
我们发现SFFQ与CFFQ在海鲜、乳制品、蛋类、水果、土豆、谷物、软饮料和加工肉类方面具有良好的相关性（斯皮尔曼等级相关性>0.5）。在肉类、甜食、蔬菜、蛋白质和碳水化合物方面发现了中等相关性（斯皮尔曼等级相关性：0.3 - 0.5）。我们发现SFFQ和CFFQ测量的总脂肪相关性较弱（斯皮尔曼等级相关性<0.3）。除肉类外，所有食物组和营养素在6个月随访期间具有足够的可重复性。
我们的SFFQ可被视为用于测量前列腺癌患者习惯性饮食摄入量的合适工具。该试验已在www.clinicaltrials.gov上注册，注册号为NCT03127631。
