摘　　要：目的编制适用于成都地区老年人群的简化膳食频率问卷（Simplified Food Frequency Questionnaire，SFFQ），并评价SFFQ的信度和效度。方法以2014年12月四川省人民医院健康体检中心老年人为研究对象，其中78人完成了两次SFFQ，92人完成了一次SFFQ和3天24小时膳食记录（3d24hDR）的调查。结果信度研究中，两次调查的能量及营养素摄入量由原始数据计算的Pearson相关系数为0．499—0．835，平均值为0．668，经对数转换、能量校正的相关系数平均值分别为0．701、0．592；效度研究中，以原始数据计算的Pearson相关系数均在0．443～0．644之间，平均值为0．539。经对数转换、能量校正所得Pearson相关系数平均值分别为0．578、0．473。结论SFFQ具有较好的信度和效度，可用于调查成都地区老年人群的慢性病与食物摄入之间的关系。Objective A 24 -item simplified food frequency questionnaire （SFFQ） is to be designed for Sichuan area, and to evaluate the reproducibility and validity of the SFFQ. Methods The SFFQ was administered among aging people who had come to Sichuan Provincial People＇s Hospital for physical examination,in which 78 interviewers accomplished twice at a short interval while 92 people completed the survey of SFFQ for once and a 3d 24h - dietary record employed as reference method was used to assess the relative validity. Results Crude Pearson correlation coefficient of the two SFFQ ranged from 0. 499 to 0. 835. Mean crude,log -transformed and energy - adjusted correlation coefficients were 0. 668,0. 701 and 0. 592, respectively. In validity evaluation, crude Pearson correlation coefficient ranged from O. 443 to 0. 644, with an average value of O. 539,0. 578,0. 473 for crude,log - transformed and energy - adjusted correlation coefficient,respectively. Conclusion The SFFQ showed a reasonable reproducibility and validity, and can be used to investigate the relationship between chronic diseases and food intake of the elderly in Chengdu.
