Abstract Background In China, many people are apt to participate in regular physical examination as a precaution. Some simplified food frequency questionnaire have been designed and used. However, the effectiveness of questionnaire is absent. This study was conducted to examine the reliability and validity of simplified food frequency questionnaire (SFFQ) used among physical examination adults in southwest region of China. Methods This study was a cross sectional study among physical health examination adults in Southwest region of China. A total of 239 participants aged 20-65 were conducted during February to June in 2019. The performance of the SFFQ was evaluated by the mean of three-day 24-hour dietary recalls (3R24). The relative validity and agreement was assessed by the Pearson`s correlation and intra-class correlation coefficients(ICC) respectively. Results The median energy-adjusted ICC of food groups between SFFQ2 and SFFQ1 was 0.59 (range: 0.49-0.73) and the ICC of nutrients was 0.47(range: 0.39-0.76). The Pearson correlation showed the validity between the SFFQ1 and 3R24, which ranged from -0.086 to 0.93 for food and and 0.21 to 0.71 for nutritions, respectively. Energy-adjustment slightly increased the correlation coefficients. Conclusions The reliability and validity of the SFFQ was acceptable. It could be an appropriate dietary assessment tool for future epidemiological studies in physical health examination adults among Chinese in southwest China.

AbstractObjectiveTo compare intra- and inter-method reliability of a semi-quantitative food frequency questionnaire (FFQ) designed specifically to measure beta carotene (BC) and retinol intake, using two methods – the limits of agreement (LOA) and the correlation coefficient.DesignA cross-sectional study of dietary intake.SettingA randomized trial of vitamin A supplements in 2769 subjects with past asbestos exposure.SubjectsData from 57 men and 26 women, aged 28–72 years, living in Western Australia.MethodsThe FFQ was administered at baseline (FFQ1) and repeated 1 year later (FFQ2). Four 1-week diet records (DRs) were completed during the year.ResultsMean agreement between FFQ2 and FFQ1 was 120% for BC and 98% for retinol. LOA were 47–306% and 21–459%, respectively. Mean agreement between FFQ2 and the DR was 149% for BC and 63% for retinol; LOA were 50–447% and 11–349%, respectively. Mean agreement and LOA varied across energy intakes. Between the DR and FFQ2, correlation coefficients were 0.36 for BC and 0.51 for retinol. These varied considerably across age, gender and energy intakes and were not in accordance with limits of agreement findings.ConclusionAlthough correlation coefficients were positive and significant, there was less than ideal intra-method and inter-method reliability shown by the limits of agreement method. Bias was uneven across the range of intakes, the LOA were wide and, compared with the DR, the FFQ significantly over-estimated BC and under-estimated retinol. This shows the limitations of calculating correlation coefficients alone, for assessing reliability and validity.

AbstractObjectives:(1) To determine the reliability and validity of a food-frequency questionnaire (FFQ) for use in epidemiological research in postmenopausal women; and (2) to compare the volume estimation (VE) and weight estimation (WE) method of administration of this questionnaire.Design:An initial list of foods was derived and modified after pre-testing in 22 subjects. Test-retest reliability was assessed in 21 subjects who had repeat administrations of the questionnaire 14 days apart (FFQ1, FFQ2). The validity of the FFQ was assessed by comparing nutrient intakes with those from a 4-day food record.Setting:Chengdu, People's Republic of China.Subjects:Twenty-two postmenopausal women (50–70 years) were recruited from The Second University Hospital, West China University of Medical Sciences, Chengdu and participated in the pre-test. Another 21 women (50–70 years) were randomly selected from the general population of all five districts of Chengdu and participated in the reliability and validity sub-studies.Results:Energy, protein, carbohydrate, magnesium and sodium intakes in this sample were less than the Recommended Dietary Allowances (RDAs) for 45–70-year-old women in China. Intake of non-cooking fat was higher than the Chinese RDA. Pearson correlation coefficients and intra-class correlation coefficients (ICCs) for reliability of the VE FFQ ranged from 0.51 to 0.85 and from 0.51 to 0.81, respectively; for the WE FFQ, they ranged from 0.22 to 0.86 and from 0.21 to 0.81. Correlation coefficients and ICCs for validity of the WE FFQ ranged from 0.36 to 0.69 and from 0.34 to 0.57, respectively; corresponding values for the VE FFQ were −0.30 to 0.65 and −0.14 to 0.65.Conclusions:Both the VE and WE FFQs were reliable and valid except for sodium intake. The VE FFQ provided more valid estimates of nutrient intakes than did the WE FFQ.
