Pdf Reproducibility And Validity Of A Food Frequency Questionnaire Food frequency questionnaire (ffq) designed to conduct qualitative or semi quantitative dietary assessment, obtains retrospective information on the pattern of foods used during a longer, less precisely defined time period (e.g. daily, weekly, monthly or year) and is used to assess habitual intake of foods or specific classes of foods [7] . We assessed the reproducibility and validity of a food frequency questionnaire (ffq) among middle aged and older adults in semarang, indonesia. a total of 259 subjects aged 40–80 years.
Pdf Validity And Reproducibility Of A Food Frequency Questionnaire We evaluated the validity and reproducibility of the ffq used in the shanghai men’s health study (smhs). the study included 195 randomly selected participants of the smhs who completed one ffq at baseline, twelve 24 hour dietary recalls (24 hdr) (once a month for twelve con secutive months) and a second ffq at the end of the study. Since no questionnaires have been validated to assess the consumption of foods with different levels of processing in the general adult population, we tested the reliability and validity of a 94 item food frequency questionnaire (nffq) designed to estimate the intake (g day) and the weight ratio (%) of the nova food groups in italian adults. We evaluated the validity and reproducibility of the ffq used in the shanghai men's health study (smhs). the study included 195 randomly selected participants of the smhs who completed one ffq at baseline, twelve 24 hour dietary recalls (24 hdr) (once a month for twelve consecutive months) and a second ffq at the end of the study. The reproducibility of the ffq was estimated with correlation coefficients, cross classification, and weighted kappa statistic. the validity was assessed by comparing the data obtained from ffq and 24 hrs. results the median nutrient intakes assessed with ffqs were higher than the average of four 24 hrs.
