Objective: To evaluate the impact of different modes of administration (face-to-face v. telephone), recall days (first v. second), clays of the week (weekday v. weekend) and interview clays (1 d later v. 2 d later) on bias in protein and K intakes collected with 24 h dietary recalls (24-HDR). %26lt;br%26gt;Design: Two non-consecutive 24-HDR (collected with standardised EPIC-Soft software) were used to estimate protein and K intakes by a face-to-face interview at the research centres and a telephone interview, and included all days of the week. Two 24 h urine collections were used to determine biomarkers of protein and K intake. The bias in intake was defined as the ratio between the 24-HDR estimate and the biomarker. %26lt;br%26gt;Setting: Five centres in Belgium, Czech Republic, France, the Netherlands and Norway in the European Food Consumption Validation (EFCOVAL) study. %26lt;br%26gt;Subjects: About 120 adults (aged 45-65 years) per centre. %26lt;br%26gt;Results: The bias in protein intake in the Czech Republic and Norway was smaller for telephone than face-to-face interviews (P=0.01). The second 24-HDR estimates of protein intake in France and K intake in Belgium had a larger bias than the first 24-HDR (P = 0.01 and 0.04, respectively). In the Czech Republic, protein intake estimated during weekends and K intake estimated during weekdays had a larger bias than during other days of the week (P = 0.01). In addition, K intake collected 2 d later in the Czech Republic was likely to be overestimated. %26lt;br%26gt;Conclusions: The biases in protein and K intakes were comparable between modes of administration, recall days, days of the week and interview days in some, but not all, study centres.
