Standard dietary questionnaires may have some limitations in cases with stroke, particularly in those suffering from language and communication difficulties. The present study aimed to develop a dietary questionnaire appropriate for patients with acute ischemic stroke (AIS). Major food groups ( = 19) were first identified using the dietary questionnaire of the INTERHEART study. Using the Food Frequency Questionnaire (FFQ), an expert dietitian and a vascular neurologist then selected a total number of 68 corresponding food items from 168 available FFQ items. In the next phase, a panel of expert dietitians ( = 10) assessed the face validity and the content validity of these 68 items and approved a total number of 62 items for the final questionnaire, namely, the Simple Stroke FFQ (SS-FFQ). Employing test-retest method, the intraclass correlation (ICC) of the SS-FFQ was subsequently calculated in 30 randomly selected cases affected with AIS. Ultimately, principal component analysis (PCA) was utilized for 153 cases with AIS to assess the construct validity of the questionnaire concerned. The SPSS Statistics software (version 18: SPSS Inc., Chicago, Illinois, United States) as well as descriptive tests including mean and percentage were additionally used to account for the baseline characteristics of the study participants. The results revealed that the reliability of the newly developed form of the SS-FFQ was perfect (ICC = 0.86). Dietary conditions were further assessed administering the SS-FFQ on 153 cases of AIS with the mean age of 63.76 ± 15.93 years. The PCA results also showed that 15 extracted items of the given questionnaire could explain 73.10% of total item variance. It was concluded that the SS-FFQ was a valid and reliable questionnaire to assess nutrient intakes among patients with AIS.
标准饮食调查问卷在中风病例中可能存在一些局限性,尤其是在那些存在语言和沟通障碍的患者中。本研究旨在开发一种适用于急性缺血性中风(AIS)患者的饮食调查问卷。首先,使用INTERHEART研究的饮食调查问卷确定主要食物组(n = 19)。然后,一位专业营养师和一位血管神经科医生使用食物频率问卷(FFQ),从168个可用的FFQ项目中总共选择了68个相应的食物项目。在下一阶段,一组专业营养师(n = 10)评估了这68个项目的表面效度和内容效度,并批准了最终问卷中总共62个项目,即简易中风FFQ(SS - FFQ)。采用重测法,随后在30例随机选择的AIS患者中计算了SS - FFQ的组内相关性(ICC)。最终,对153例AIS患者进行主成分分析(PCA),以评估相关问卷的结构效度。此外,还使用了SPSS统计软件(版本18:SPSS公司,美国伊利诺伊州芝加哥)以及包括均值和百分比在内的描述性测试来描述研究参与者的基线特征。结果显示,新开发的SS - FFQ形式的信度极佳(ICC = 0.86)。对153例平均年龄为63.76 ± 15.93岁的AIS患者进行SS - FFQ评估,进一步分析饮食状况。PCA结果还表明,给定问卷中提取的15个项目可以解释总项目方差的73.10%。得出的结论是,SS - FFQ是一种有效且可靠的问卷,可用于评估AIS患者的营养摄入量。
