Methodological studies should be conducted to address how well a given assessment method captures dietary intake and to highlight the extent and direction of the measurement error. Within a subgroup of the Hordaland Health Study (HUSK3), we examined the relative validity of a web-based food frequency questionnaire (WebFFQ) by comparing its estimates of mean daily intake of nutrients and foods with estimated mean daily intakes from repeated administrations of 24-hour dietary recall interviews (24-HDRs). Men and women born between 1950 and 1951 were recruited from HUSK3. The participants (\n                    <jats:italic>n =<\/jats:italic>\n                    67) completed a WebFFQ and three non-consecutive 24-HDRs over the course of a year. Relative validity was assessed using Spearman's rank correlation, crosstab analysis and Bland\u2013Altman plots. Linear regression models were used to compute the calibration coefficients. The estimated correlation coefficients were acceptable or strong for all nutrients and foods except iodine (\n                    <jats:italic>\n                      r\n                      <jats:sub>s<\/jats:sub>\n                    <\/jats:italic>\n                    = 0\u22c519). The highest correlation coefficient was found for juice (\n                    <jats:italic>\n                      r\n                      <jats:sub>s<\/jats:sub>\n                    <\/jats:italic>\n                    = 0\u22c571), whereas the lowest correlation coefficient was found for iodine (\n                    <jats:italic>\n                      r\n                      <jats:sub>s<\/jats:sub>\n                    <\/jats:italic>\n                    = 0\u22c519). Cross-classification by quartiles categorised more than 72 % of the participants into the same or adjacent quartiles using the two methods. Few data points fell outside the limits of agreement in the Bland\u2013Altman plots. Calibration coefficients ranged from 0\u22c510 (wholegrain) to 0\u22c581 (alcohol). Our findings suggest that the WebFFQ has reasonable ranking abilities for all the included nutrients and foods, except for iodine.\n                  <\/jats:p>","DOI":"10.1017\/jns.2022.97","type":"journal-article","created":{"date-parts":[[2022,11,4]],"date-time":"2022-11-04T03:42:29Z","timestamp":1667533349000},"source":"Crossref","is-referenced-by-count":19,"title":["Comparison of dietary intake measured by a web-based FFQ and repeated 24-hour dietary recalls: the Hordaland Health Study"],"prefix":"10.1017","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0744-5611","authenticated-orcid":false,"given":"Zoya","family":"Sabir","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanne","family":"Rosendahl-Riise","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jutta","family":"Dierkes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helene","family":"Dahl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anette","family":"Hjart\u00e5ker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2022,11,4]]},"reference":[{"key":"S2048679022000970_ref32","doi-asserted-by":"publisher","DOI":"10.1186\/s12937-018-0368-4"},{"key":"S2048679022000970_ref15","doi-asserted-by":"publisher","DOI":"10.1079\/NRR200370"},{"key":"S2048679022000970_ref3","doi-asserted-by":"publisher","DOI":"10.1017\/S0007114517003178"},{"key":"S2048679022000970_ref1","doi-asserted-by":"publisher","DOI":"10.12688\/f1000research.10703.1"},{"key":"S2048679022000970_ref11","doi-asserted-by":"publisher","DOI":"10.3389\/fnut.2019.00145"},{"key":"S2048679022000970_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jand.2019.06.010"},{"key":"S2048679022000970_ref22","doi-asserted-by":"publisher","DOI":"10.1017\/S1368980013000268"},{"key":"S2048679022000970_ref33","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph16234722"},{"key":"S2048679022000970_ref39","doi-asserted-by":"publisher","DOI":"10.1186\/1475-2891-12-75"},{"key":"S2048679022000970_ref17","volume-title":"M\u00e5l, Vekt og Porsjonsst\u00f8rrelser for Matvarer","author":"Dalane","year":"2015"},{"key":"S2048679022000970_ref45","doi-asserted-by":"publisher","DOI":"10.1186\/s12937-019-0489-4"},{"key":"S2048679022000970_ref20","volume-title":"Norkost 3, National Dietary Survey in Men and Women in Norway Aged 18\u201370 Years","author":"Totland","year":"2012"},{"key":"S2048679022000970_ref16","doi-asserted-by":"publisher","DOI":"10.1093\/acprof:oso\/9780199754038.001.0001"},{"key":"S2048679022000970_ref44","doi-asserted-by":"publisher","DOI":"10.29219\/fnr.v62.1291"},{"key":"S2048679022000970_ref10","doi-asserted-by":"publisher","DOI":"10.1079\/PHN2002383"},{"key":"S2048679022000970_ref29","doi-asserted-by":"publisher","DOI":"10.1186\/s12937-015-0121-1"},{"key":"S2048679022000970_ref38","first-page":"1","article-title":"Validity of the food frequency questionnaire for adults in nutritional epidemiological studies: a systematic review and meta-analysis","author":"Cui","year":"2021","journal-title":"Crit Rev Food Sci Nutr"},{"key":"S2048679022000970_ref9","doi-asserted-by":"publisher","DOI":"10.1080\/16546628.2017.1305193"},{"key":"S2048679022000970_ref23","unstructured":"23.
