Reproducibility And Construct Validity Of A Food Frequency Results: reproducibility as measured by icc was 0.50 0.77 for saturated fatty acids (sfa) and energy in urban and 0.61 0.72 for protein and sfa in rural areas. the icc for food groups was. Limited information is avail able to assess the validity of ffq used among malaysian adolescents. objective: to construct the validity and re producibility of a newly developed ffq in assessing habitual nutrients intake over the past year of 170 malay ad olescent boys and girls in kelantan, malaysia.
Pdf Reproducibility And Validity Of A Food Frequency Questionnaire To Reproducibility was assessed using intra cluster correlation coefficients (icc). construct validity of carbohydrate and fat intake was assessed using baseline serum lipids by regression analysis. results: reproducibility as measured by icc was 0.50 0.77 for saturated fatty acids (sfa) and energy in urban and 0.61 0.72 for protein and sfa in. Construct validity of carbohydrate and fat intake was assessed using baseline serum lipids by regression analysis. results reproducibility as measured by icc was 0.50 0.77 for saturated fatty acids (sfa) and energy in urban and 0.61 0.72 for protein and sfa in rural areas. The reproducibility of ffq in this study was evaluated at three levels between ffq1 and ffq2, i.e. comparison of the mean intake of foods and nutrients; correlation analysis of their intake; and cross classification and agreement on their corresponding intake. the results showed a high degree of reproducibility for both foods and nutrients. The results demonstrated that the ffq had reasonable reproducibility (correlation coefficients ≥0.58 and weighted κ statistic > 0.45) for all selected food and nutrients and fair to moderate validity (correlation coefficients > 0.40 and weighted κ coefficients > 0.3) for most of the food and nutrients.
Pdf Reproducibility And Relative Validity Of The Food Frequency The reproducibility of ffq in this study was evaluated at three levels between ffq1 and ffq2, i.e. comparison of the mean intake of foods and nutrients; correlation analysis of their intake; and cross classification and agreement on their corresponding intake. the results showed a high degree of reproducibility for both foods and nutrients. The results demonstrated that the ffq had reasonable reproducibility (correlation coefficients ≥0.58 and weighted κ statistic > 0.45) for all selected food and nutrients and fair to moderate validity (correlation coefficients > 0.40 and weighted κ coefficients > 0.3) for most of the food and nutrients. The purpose of the present study was to evaluate the reproducibility and relative validity and calibrate the dietary intake assessment of a food frequency questionnaire (ffq) using a random. Results reproducibility as measured by icc was 0.50 0.77 for saturated fatty acids (sfa) and energy in urban and 0.61 0.72 for protein and sfa in rural areas. the icc for food groups was 0.53 0.77 for whole grains, fruits and vegetables in urban and 0.50 0.89 for animal foods and whole grains in rural areas. Objective: to evaluate the validity and reproducibility of a food frequency questionnaire (ffq) developed for assessing the association between dietary factors and breast cancer risk among chinese women in guangdong. methods: 61 women (24 64 years) were recruited from the community in guangzhou city. Reproducibility was assessed using intra cluster correlation coefficients (icc). construct validity of carbohydrate and fat intake was assessed using baseline serum lipids by regression analysis.
